High risk hypertensives: pre-hospital management of acute myocardial infarction--results from the French nationwide registry USIC 2000.

OBJECTIVE: To assess the use of mobile coronary care units (MCU) in hypertensive patients previously treated for cardiovascular diseases in comparison with those with no history of cardiovascular disease and to estimate the influence of the use of MCU on cardiovascular outcome in this population. PATIENTS: We used a nationwide prospective registry of all patients admitted for AMI in French intensive care units in 2000. Patients without history of hypertension or patients admitted with pulmonary oedema or cardiogenic shock were excluded. Men (N = 514) and women (N = 291) were analysed separately. RESULTS: The proportion of patients with history of myocardial infarction, peripheral artery disease and stroke was not significantly higher in subjects who used physician-staffed MCU as compared with patients with no history of myocardial infarction, peripheral artery disease or stroke. In each sex, revascularization (pre hospital fibrinolysis, in hospital fibrinolysis or coronary angioplasty) were more frequent in patients who used MCU. Also, one year cardiovascular mortality was lower in men who used MCU. CONCLUSION: Known high risk hypertensive patients did not use physician-staffed MCU more than subjects free of such condition. Education of hypertensive patients at risk during routine visits is required to increase of the use of physician-staffed MCU in case of symptoms suggestive of AMI.

Major impact of admission glycaemia on 30 day and one year mortality in non-diabetic patients admitted for myocardial infarction: results from the nationwide French USIC 2000 study.

OBJECTIVE: To analyse the short and long term prognostic significance of admission glycaemia in a large registry of non-diabetic patients with acute myocardial infarction. METHODS: Assessment of short and long term prognostic significance of admission blood glucose in a consecutive population of 1604 non-diabetic patients admitted to intensive care units in France in November 2000 for a recent (<or= 48 hours) myocardial infarction. RESULTS: In-hospital mortality, compared with that of patients with admission glycaemia below the median value of 6.88 mmol/l (3.7%), rose gradually with each of the three upper sextiles of glycaemia: 6.5%, 12.5% and 15.2%. Conversely, one year survival decreased from 92.5% to 88%, 83% and 75% (p < 0.001). Admission glycaemia remained an independent predictor of in-hospital and one year mortality after multivariate analyses accounting for potential confounders. Increased admission glycaemia also was a predictor of poor outcome in all clinical subsets studied: patients without heart failure on admission, younger and older patients, patients with or without reperfusion therapy, and patients with or without ST segment elevation. CONCLUSION: In non-diabetic patients, raised admission blood glucose is a strong and independent predictor of both in-hospital and long term mortality.

[Management of patients admitted for acute myocardial infarction in France from 1995 to 2000: time to admission dependent improvement in outcome].

The in-hospital management and short- and long-term outcomes was assessed in 2 registries of consecutive patients admitted for acute myocardial infarction, 5 years apart, in France. The 2000 cohort was younger and with a less frequent history of cardiac diseases, but was more often diabetic and with anterior infarcts. Time to admission was actually longer in 2000 than in 1995 (median 5.25 hours vs 4.00 hours). Overall, reperfusion therapy was used in 43% of the patients in both registries. However, the use of reperfusion therapy increased from 1995 to 2000 in patients admitted within 6 hours of symptom onset (64 vs 58%), with an increasing use of primary angioplasty (from 12 to 30%). Five-day mortality significantly improved from 7.7 to 6.1% (p < 0.03) and one-year survival was also less in the most recent period (85 vs 81%, p < 0.01). Multivariate analyses showed that the period of inclusion (2000 vs 1995) was an independent predictor of both short- and long-term mortality in patients admitted within 6 hours of symptom onset. Thus, in the real world setting, a continued decline in one-year mortality was observed in patients admitted to intensive care units for recent acute myocardial infarction, especially for patients admitted early. This goes along with a shift in reperfusion therapy towards a broader use of primary angioplasty, and with an increased use of the early prescription of recognised secondary prevention medications.

[Evolution of the management and outcomes of patients admitted for acute myocardial infarction in France from 1995 to 2000: data from the USIK 1995 and USIC 2000 nationwide registries].

We assessed the in-hospital management and short- and long-term outcomes of two series of patients admitted for acute myocardial infarction, 5 years apart, in France. The most recent cohort was younger and with a less frequent history of cardiac diseases, but was more often diabetic and with anterior infarcts. Five-day mortality significantly improved from 7.7% to 6.1% (P < 0.03) and 1-year survival was also less in the most recent period (15% versus 19%, P < 0.01). Multivariate analyses showed that the period of inclusion (2000 versus 1995) was an independent predictor of both short- and long-term mortality. In analyses restricted to the patients who were alive by day 5, initial treatment with statins was associated with a 38% decrease in the risk of death at 1 year. Likewise, in patients with left ventricular ejection fraction < or = 35%, the early prescription of ACE inhibitors was associated with a 41% reduction in the risk of 1-year mortality. Thus, in the real world setting, a continued decline in 1-year mortality is observed in patients admitted to intensive care units for recent acute myocardial infarction. This goes along with a shift in reperfusion therapy towards a broader use of coronary angioplasty and with an increased use of the early prescription of recognised secondary prevention medications.

Detection of masked hypertension by home blood pressure measurement: is the number of measurements an important issue?

BACKGROUND: Office blood pressure (OBP) and home blood pressure (HBP) enable the identification of patients with masked hypertension. Masked hypertension is defined by normal OBP and high HBP and is known as a pejorative cardiovascular risk factor. OBJECTIVE: The objective was to evaluate in the SHEAF study the influence of the number of office or home blood pressure measurements on the classification of patients as masked hypertensives. METHODS: Patients with OBP <140/90 mmHg (mean of six values: three measurements at two separate visits, V1 and V2) and HBP >135/85 mmHg (mean of all valid measurements performed over a 4-day period) were the masked hypertensive reference group. The consistency of the classification was evaluated by using five definitions of HBP values (mean of the 3, 6, 9, 12 and 15 first measurements) and two definitions of OBP values (mean of three measurements at V1 and mean of three measurements at V2). RESULTS: Among the 4939 treated hypertensives included in the SHEAF study, 463 (9.4%) were classified as masked hypertensives (reference group). By decreasing the number of office or home measurements, the prevalence of masked hypertension ranged from 8.9-12.1%. The sensitivity of the classification ranged from 94-69% therefore 6-31% of the masked hypertensives were not detected. The specificity ranged from 98-94% therefore 1-6% of patients were wrongly classified as masked hypertensives. CONCLUSION: A limited number of home and office BP measurements allowed the detection of masked hypertension with a high specificity and a low sensitivity. A sufficient number of measurements (three measurements at two visits for OBP and three measurements in the morning and in the evening over 2 days for HBP) are required to diagnose masked hypertension.

Management and in-hospital outcome of patients with acute myocardial infarction admitted to intensive care units at the turn of the century: results from the French nationwide USIC 2000 registry.

OBJECTIVE: To assess actual practices and in-hospital outcome of patients with acute myocardial infarction on a nationwide scale. METHODS: Of 443 intensive care units in France, 369 (83%) prospectively collected data on all cases of infarction (within < 48 hours of symptom onset) in November 2000. RESULTS: 2320 patients (median age 68 years, 73% men) were included, of whom 83% had ST segment elevation infarction (STEMI). Patients without STEMI were older and had a more frequent history of cardiovascular disease. Median time to admission was 5.0 hours for patients with and 6.5 hours for those without STEMI. Reperfusion therapy was used for 53% of patients with STEMI (thrombolysis 28%, primary angioplasty 25%). In-hospital mortality was 8.7% (5.5% of patients without and 9.3% of those with STEMI). Multivariate analysis found that age, Killip class, lower blood pressure, higher heart rate on admission, anterior location of infarct, STEMI, diabetes mellitus, previous stroke, and no current smoking independently predicted in-hospital mortality. At hospital discharge, 95% received antiplatelet agents, 75% received beta blockers, and over 60% received statins. Angiotensin converting enzyme inhibitors were prescribed for 40% of the patients without and 52% of those with ST elevation. CONCLUSIONS: This nationwide registry, including all types of centres irrespective of their size and experience, shows continued improvement in patient care and outcomes. Time from symptom onset to admission, however, has not improved in recent years and reperfusion therapy is used for just over 50% of patients with STEMI, with an increasing use of primary angioplasty.

[Trends in discharge prescriptions for patients hospitalized for acute coronary syndromes in France from 1995 to 2000. Data from the Usik 1995, Prevenir 1, Prevenir 2 and Usic 2000 surveys].

The use of cardiovascular secondary prevention medications in patients with acute coronary syndromes was compared in 4 sequential observational surveys carried out in France from 1995 to 2000. The Usik 1995 and Usic 2000 surveys included patients admitted for acute myocardial infarction, while the 2 Prevenir surveys (1998 and 1999) assessed the medications prescribed in patients with acute coronary syndromes. Antiplatelet agents were prescribed in 91% of the patients in 1995, 93% in 1998 and 1999 and 96% in 2000; for beta-blockers, the respective figures were: 64%, 68%, 75% and 76%. For ACE-Inhibitors, the figures were: 46%, 41%, 41% and 50%. For statins, the prescription increased from 10% to 36%, 59% and 64%. In 1995, 8% of the patients received both antiplatelet agents, beta-blockers and statins (4% of them also had an ACE-Inhibitor); in 2000, the respective figures were 53% and 27%. The results of the recent trials of secondary prevention medications have had a considerable impact on real-life practice in France during the late 1990s.

Control of diabetes and cardiovascular risk factors in patients with type 2 diabetes: a nationwide French survey.

OBJECTIVES: To evaluate in France in 2001 the therapeutic management and control of diabetes and of modifiable cardiovascular risk factors in patients with type 2 diabetes receiving specialist care. METHODS: The study was proposed to 575 diabetologists across France. The first 8 consecutive ambulatory patients with type 2 diabetes treated by oral antidiabetic drugs (OADs) and/or insulin attending for consultation with a diabetologist were eligible for inclusion in the survey. The following data were collected: demographics, diabetic and cardiovascular history, cardiovascular risk factors, blood pressure, last recorded measurements of HbA(1c) and LDL cholesterol, and details of diabetes medication and cardiovascular medication. RESULTS: 4, 930 patients (53% men) aged 62 +/- 11 years were recruited by 410 specialists in diabetes care. The mean duration of diabetes was 12 +/- 9 years. 71% of patients were treated with OADs, 18% with an OAD + insulin and 9% with insulin alone. Mean HbA(1c) was 7.6 +/- 1.6%; HbA(1c) was<=6.5% in 27% of patients, between 6.6% and 8% in 39% of patients, and > 8% in 34% of patients. Mean blood pressure was 140 +/- 16/80 +/- 9 mmHg. In the study population as a whole the target blood pressure (systolic BP<140 mmHg and diastolic BP<80 mmHg) was attained by 29% of patients. Among the 3, 085 patients (63%) treated for hypertension, this target was attained in only 23% of patients; 40% of patients treated for hypertension received one single antihypertensive treatment, 36% received 2 treatments and 24% received 3 treatments or more. Among the 1, 845 patients considered by the investigators as not having hypertension, the target blood pressure was attained by 39%. A measurement for LDL cholesterol was available in 4, 036 patients (82%). 58% of these patients had LDL cholesterol<1.3 g/l, 29% had values between 1.3 and 1.6 g/l, and 13% had values > 1.6 g/l. 52% of patients were not receiving any lipid-lowering agents, 28% were treated with statins, 19% with fibrates, and 1% with statins + fibrates. LDL cholesterol was<1.3 g/l in only 66% of the 646 patients with associated coronary heart disease. CONCLUSION: According to this large nationwide survey, the prevalence of cardiovascular risk factors remains high. Control of glycaemia, blood pressure and LDL cholesterol does not appear to be optimal. This is due in part to the severity of diabetes in these patients seen by specialists in diabetes care; however, both awareness and application of published recommendations need to be reinforced.

Is "isolated home" hypertension as opposed to "isolated office" hypertension a sign of greater cardiovascular risk?

BACKGROUND: The SHEAF (Self-Measurement of Blood Pressure at Home in the Elderly: Assessment and Follow-up) study is an observational study (from February 1998 to early 2002) designed to determine whether home blood pressure (BP) measurement has a greater cardiovascular prognostic value than office BP measurement among elderly (> or =60 years) French patients with hypertension. The objective of this present work is to describe the baseline characteristics of the treated patients in the SHEAF study from February 1998 to March 1999, placing special emphasis on "isolated office" and "isolated home" hypertension. METHODS: Baseline office BP measurement was assessed using a mercury sphygmomanometer. Home BP measurement was performed over a 4-day period. A 140/90-mm Hg threshold was chosen to define office hypertension, and a 135/85-mm Hg threshold to define home hypertension. RESULTS: Of the 5211 hypertensive patients in the SHEAF study with a valid home BP measurement, 4939 received treatment with at least 1 antihypertensive drug. Patients with isolated office hypertension represented 12.5% of this population, while patients with isolated home hypertension represented 10.8%. The characteristics of the patients with isolated office hypertension were similar to those of patients with controlled hypertension. However, patients with isolated office hypertension had fewer previous cardiovascular complications. In contrast, rates of cardiovascular risk factors and history of cardiovascular disease in patients with isolated home hypertension resembled those in patients with uncontrolled hypertension. CONCLUSIONS: This retrospective analysis suggests that patients with isolated home hypertension belong to a high-risk subgroup. The 3-year follow-up of these patients will provide prospective data about the cardiovascular prognosis of these subgroups.

Blood pressure levels, risk factors and antihypertensive treatments: lessons from the SHEAF study.

OBJECTIVES: The SHEAF study (Self measurement of blood pressure at Home in the Elderly: Assessment and Follow-up) is a 3-year prospective cohort study of French elderly (> or =60 years) hypertensive patients designed to assess whether home blood pressure (HBP) measurement provides additional prognostic information over office blood pressure (OBP) in terms of cardiovascular mortality and morbidity. The objective of the present work is to describe the baseline data of the population enrolled in the SHEAF study with special emphasis on blood pressure control in treated hypertensives. METHODS: During the 2-week initial inclusion phase, baseline demographics, cardiovascular risk factors, antihypertensive treatments as well as office and home blood pressure were recorded. Baseline OBP was assessed using a mercury sphygmomanometer (three consecutive measurements during two visits performed 2 weeks apart). HBP was performed over a 4-day period (three consecutive measurements in the morning and in the evening). RESULTS: A total of 4939 (95%) of the 5211 patients included in the SHEAF study were treated with at least one antihypertensive drug. Their ages ranged from 60 to 99 years (mean age 70 +/- 7 years); 49% were men, 12% had a previous history of coronary artery disease, 14% diabetes and 43% a treated dyslipidaemia. A total of 45% of the treated patients received a single antihypertensive drug, 34% two drugs, 21% three drugs or more. Overall 23% of treated hypertensives were normalised at the doctor's office (systolic BP <140 mm Hg and diastolic BP <90 mm Hg) and 27% at home (home systolic BP <135 mm Hg and home diastolic BP <85 mm Hg). Poor blood pressure control was associated with age, an increasing presence of diabetes and prescription of several antihypertensives. The proportion of subjects with controlled blood pressure decrease with age from 26% (60-69 years) to 21% (> or =80 years). Blood pressure control of diabetic patients was particularly poor as only 19% had an OBP <140/90 mm Hg and 6% a blood pressure <130/85 mm Hg. The percentage of patients with controlled OBP decreased from 26% when receiving a single antihypertensive drug to 11% when receiving four antihypertensives or more. CONCLUSION: In the SHEAF study, less than one-third of the patients had an OBP adequately controlled thus confirming previous studies performed in younger populations. Presence of associated cardiovascular risk factors including diabetes did not give rise to a better blood pressure control. When blood pressure control was assessed using HBP measurement similar results were found. As the beneficial effect of antihypertensive treatment has been particularly well established in the elderly, the data of this study underlines the need for a closer and more rigorous management of elderly hypertensives.

Comparison of three blood pressure measurement methods for the evaluation of two antihypertensive drugs: feasibility, agreement, and reproducibility of blood pressure response.

Our objective was to compare three different methods of blood pressure measurement through the results of a controlled study aimed at comparing the antihypertensive effects of trandolapril and losartan. Two hundred and twenty-nine hypertensive patients were randomized in a double-blind parallel group study. After a 3-week placebo period, they received either 2 mg trandolapril or 50 mg losartan once daily for 6 weeks. At the end of both placebo and active treatment periods, three methods of blood pressure measurement were used: a) office blood pressure (three consecutive measurements); b) home self blood pressure measurements (SBPM), consisting of three consecutive measurements performed at home in the morning and in the evening for 7 consecutive days; and c) ambulatory blood pressure measurements (ABPM), 24-h BP recordings with three measurements per hour. Of the 229 patients, 199 (87%) performed at least 12 valid SBPM measurements during both placebo and treatment periods, whereas only 160 (70%) performed good quality 24-h ABPM recordings during both periods (P < .0001). One hundred-forty patients performed the three methods of measurement well. At baseline and with treatment, agreement between office measurements and ABPM or SBPM was weak. Conversely, there was a good agreement between ABPM and SBPM. The mean difference (SBP/DBP) between ABPM and SBPM was 4.6 +/- 10.4/3.5 +/- 7.1 at baseline and 3.5 +/- 10.0/4.0 +/- 7.0 at the end of the treatment period. The correlation between SBPM and ABPM expressed by the r coefficient and the P values were the following: at baseline 0.79/0.70 (< 0.001/< .0001), with active treatment 0.74/0.69 (0.0001/.0001). Hourly and 24-h reproducibility of blood pressure response was quantified by the standard deviation of BP response. Compared with office blood pressure, both global and hourly SBPM responses exhibited a lower standard deviation. Hourly reproducibility of SBPM response (10.8 mm Hg/6.9 mm Hg) was lower than hourly reproducibility of ABPM response (15.6 mm Hg/11.9 mm Hg). In conclusion, SBPM was easier to perform than ABPM. There was a good agreement between these two methods whereas concordance between SBPM or ABPM and office measurements was weak. As hourly reproducibility of SBPM response is better than reproducibility of both hourly ABPM and office BP response, SBPM seems to be the most appropriate method for evaluating residual antihypertensive effect.

Treatment of acute myocardial infarction by primary coronary angioplasty or intravenous thrombolysis in the "real world": one-year results from a nationwide French survey.

BACKGROUND: Recent randomized trials comparing primary coronary angioplasty and intravenous thrombolysis at the acute stage of myocardial infarction have shown a limited but definite advantage for primary angioplasty. The aim of this study was to document 1-year outcome in patients receiving either thrombolysis or primary angioplasty for acute myocardial infarction in the "real world." METHODS AND RESULTS: We used a nationwide prospective registry of all patients admitted for acute myocardial infarction in French intensive care units in November 1995. Of the 721 patients who received reperfusion therapy, 152 were treated with primary angioplasty and 569 received intravenous thrombolysis. The two groups were remarkably similar with respect to all baseline descriptors, except that a higher proportion of patients in the angioplasty group had a history of cerebrovascular accident (10% versus 2%, P<0.01). In-hospital outcome was not different in the 2 groups. One-year survival was 85.5% in the angioplasty group and 89. 5% in the thrombolysis group (P=0.18). Multivariate analysis showed that older age, anterior location of infarction, female sex, and history of heart failure were related to 1-year mortality. In patients alive on day 5, the use of primary angioplasty and higher Killip class were additional adverse prognostic indicators. CONCLUSIONS: The results of this large registry of real-world practice indicate no survival benefit for patients treated with primary angioplasty compared with those who received thrombolytic therapy.

[Current aspects of arterial hypertension. Prognostic value of self-monitoring blood pressure measurements in aged hypertensive patients: a SHEAF study protocol].

HOW TO MEASURE BLOOD PRESSURE: Studies conducted in large series have established the prognostic value of blood pressure measured by conventional methods. This measurement technique has however a certain number of limitations and alternative systems have been proposed, including self-monitoring methods. A preliminary study suggested that the prognostic value of self-monitoring blood pressure measurements would be superior to those obtained with conventional methods. These findings require confirmation. A LARGE SCALE STUDY: The primary objective of the SHEAF study is to determine the prognostic value of self-monitoring blood pressure measurements in terms of cardiovascular mortality in a population of hypertensive elderly subjects living in France. The study protocol projects to include 5,000 hypertensive patients, whether treated or not, aged 60 and over. Baseline pressures are to be measured by a physician using a mercury sphygmomanometer (3 successive measurements at 2 visits) and by the participants using a self-monitoring device in their home (3 measurements in the morning and evening for 4 consecutive days). The patients will be followed for 3 years and all cardiovascular events will be recorded, including: death, myocardial infarction, cerebral vascular events, transitory ischemic events, hospitalization for angina, episodes of angina, heart failure, angioplasy or coronary bypass. The results of this large-scale epidemiology study should be available in 2002. METHODOLOGICAL PRECAUTIONS: The SHEAF study will analyze the patient's usual blood pressures, whatever the treatment at study inclusion, rather than blood pressures observed after treatment withdrawal. Efforts will be made to limit the number of drop-outs.

Epidemiology of myocardial infarction in France: therapeutic and prognostic implications of heart failure during the acute phase.

BACKGROUND: The aim of this study was to assess the 1-year outcome of acute myocardial infarction, in current practice, according to the presence or absence of heart failure. This was an epidemiologic, prospective survey involving 2152 patients recruited in November 1995 from 312 French coronary care units. METHODS AND RESULTS: All consecutive patients admitted within 48 hours for confirmed acute myocardial infarction to the participating centers in November 1995 were included. For each patient, baseline parameters, as well as clinical course and therapeutic treatment during the first 5 days, were collected. For the purpose of this study, the diagnosis of heart failure required a left ventricular ejection fraction </=35% and/or a Killip class >1. During the 1-year follow-up, date and cause of death were recorded. Kaplan-Meier survival curves were analyzed with the log rank test. Cox multivariate analyses were used to assess the independent prognostic factors among 5-day survivors. Eight hundred twenty-one (38%) patients exhibited heart failure during the first 5 days after myocardial infarction. Patients with heart failure were 10 years older and were more likely to be hypertensive or diabetic; use of primary revascularization (33% vs 47%, P <.001) and beta-blockers (40% vs 79%, P <.001) was less frequent, whereas prescription of angiotensin-converting enzyme (ACE) inhibitors was enhanced (56% vs 41%, P <.001). Mortality rate was strongly related to both left ventricular ejection fraction (P <. 001) and Killip class (P <.001). One-year mortality rate was 39.7% in patients with heart failure compared with 7.1% in patients without heart failure (P <.001). A significant reduction in mortality rates was observed with beta-blockers (risk ratio 0.63 [0. 45 to 0.89], P =.01) and ACE inhibitors (risk ratio 0.73 [0.54 to 0. 99], P =.04). It was more pronounced in patients with heart failure. CONCLUSIONS: Results of this French observational survey are in line with previous epidemiologic studies and with major therapeutic trials. Patients with heart failure after acute myocardial infarction constitute a high-risk group. They appear to derive a greater benefit from treatment with both beta-blockers and ACE inhibitors than from each class on its own.

[Prognosis after myocardial infarct in a diabetic patient: results of coronary intensive care unit epidemiological study].

OBJECTIVE: Determine early and mid-term mortality in diabetic patients with myocardial infarction and ascertain whether diabetes is an independent prognosis factor. PATIENTS AND METHODS: All patients admitted to an intensive care unit within 48 hours of the first signs of myocardial infarction were included in the study. Diabetic status was recorded at admission. Early mortality (5 day) and 1-year mortality was compared between diabetic and non-diabetic patients. Multivariate analysis was used to determine the predictive value of diabetic status as an independent factor. RESULTS: 2527 patients, including 440 diabetics (17%) and 2087 non-diabetics (83%) were followed at 5 days; 2125 patients, including 364 diabetics (17%) and 1761 non-diabetics (83%) were followed to 1 year. Diabetes was more frequent in older patients and in women. Mortality in diabetic patients was higher than in non-diabetics. At 5 days, mortality was 10.4% versus 17.6% (p < 0.001). Multivariate analysis did not confirm diabetic status as an independent risk factor for death at 5 days. Inversely, at 1 year, diabetic status was an independent risk factor (RR = 1.4; 95% CI = 1.1 -1.8; p = 0.004). CONCLUSION: Diabetes is associated with poor prognosis after myocardial infarction. After correction for other risk factors, diabetes is an independent risk factor which must be taken into account when managien after myocardial infarction.

Ambulatory blood pressure and urinary albumin excretion in diabetic (non-insulin-dependent and insulin-dependent) hypertensive patients: relationships at baseline and after treatment by the angiotensin converting enzyme inhibitor trandolapril.

The aim of the present study was to examine the relationships between ambulatory blood pressure (ABPM) and urinary albumin excretion (UAE) in diabetic (non-insulin dependent [NIDDM] and insulin-dependent [IDDM]) hypertensives at baseline and after treatment by an angiotensin converting enzyme (ACE) inhibitor. After a 3-week placebo period, patients were treated for 16 weeks with trandolapril, 2 to 4 mg/day. The UAE and blood pressure (mercury sphygmomanometer and 24-h ABPM) were measured at baseline and repeated on trandolapril. Predictive factors of abnormal UAE (24-h UAE > or = 30 mg) were determined using univariate and multivariate analysis (logistic regression). Predictors of UAE decrease were also searched. One hundred seventy-one patients entered the analysis. Baseline office BP was 164+/-14 / 97+/-6 mm Hg and 24-h BP was 142+/-17 / 83+/-10 mm Hg. Seventy-four patients (43%) had UAE > or = 30 mg. Independent risk factors for abnormal UAE were nighttime diastolic BP (odds ratio [OR] = 4.1, confidence interval [CI] = 2.0 to 8.6, P = .0001), diabetes duration (OR = 2.4, CI = 1.1 to 5.0, P = .025), and presence of retinopathy (OR = 3.2, CI = 1.0 to 10.0, P = .047). Conversely, office BP level was not significantly related to UAE. On treatment, office BP levels decreased to 143+/-13 / 82+/-8 mm Hg (P < .0001) and 24-h BP levels to 134+/-17 / 78+/-9 mm Hg (P < .0001). In the abnormal UAE group, UAE significantly decreased from 76 to 50 mg/day (P = .006). After treatment, independent predictive factors of abnormal UAE were: on-drug fasting plasma glucose (OR = 3.5, CI = 1.7 to 7.4, P = .0009) and on-drug nighttime diastolic BP (OR = 3.5, CI = 1.7 to 7.4, P = .001). The only predictor of UAE decrease was a 24-h systolic BP decrease (OR = 2.3, CI = 1.3 to 4.3, P = .007). We conclude that in diabetic hypertensives with abnormal UAE, trandolapril exhibited a sustained 24-h antihypertensive effect and provided a consistent reduction of microalbuminuria. This study confirmed the superiority of ABPM over clinical BP to predict target organ damage.

Superiority of home blood pressure measurements over office measurements for testing antihypertensive drugs.

OBJECTIVE: To compare the effects on office blood pressure and home blood pressure of placebo and active drug administration. DESIGN: After a 2-week wash-out period, patients with mild-to-moderate hypertension entered a 2-week single-blind placebo period and then a 4-week double-blind period. Patients were randomly assigned to be administered either 2 mg trandolapril once daily or its placebo in a 2:1 proportion. Office blood pressure was measured by a physician at the end of each period, using a mercury sphygmomanometer (mean of three consecutive measurements). Home blood pressure was measured during the last week of each period according to standard procedure carefully taught to each patient by the physician. Compliance was checked by using electronic pill boxes. RESULTS: Data for 34 of the 44 patients who entered the study were eligible for analysis. Baseline systolic blood pressure/diastolic blood pressure were significantly (P = 0.0001/P = 0.0001) higher for office blood pressure (161/101 mmHg) than they were for home blood pressure (145/93 mmHg). There was no statistically significant difference between the placebo and active-treatment groups at baseline. During the single-blind period, blood pressures measured at the office and at home did not change significantly. Office blood pressure decreased by 2.7 +/- 10 mmHg for systolic blood pressure and by 0.5 +/- 4 mmHg for diastolic blood pressure whereas home blood pressure increased by 0.8 +/- 6 mmHg for systolic blood pressure and by 0.7 +/- 4 mmHg for diastolic blood pressure. During the double-blind period, office blood pressure fell significantly with trandolapril treatment (systolic by 10.2 +/- 12 mmHg, diastolic by 8.3 +/- 6 mmHg; P = 0.0005/0.0001, versus single-blind placebo period) but this decrease was not significantly different (P = 0.45/0.92) from the fall in members of the placebo group (systolic by 6.9 +/- 9 mmHg, diastolic by 8.0 +/-6 mmHg; P = 0.04/0.002, versus single-blind placebo period). Thus, no antihypertensive effect of trandolapril was demonstrated. The fall lin home blood pressure with trandolapril treatment was significant (systolic by 10.7 +/- 8 mmHg, diastolic by 5.8 +/- 5 mmHg; both P = 0.0001, versus single-blind placebo period) and was significantly greater (P = 0.0004/0.004) than the minimal change observed with placebo (systolic fell by 0.2 +/- 5mmHg, diastolic fell by 0.6 +/- 4 mmHg; P = 0.90/0.62, respectively, versus single-blind placebo period). The evening decrease in home blood pressure was similar to the morning decrease in home blood pressure in members of the trandolapril-treated group. The resulting morning:evening decrease in blood pressure ratio was 0.83 for diastolic blood pressure and 0.95 for systolic blood pressure. For the subgroup of responders, mean of individual ratios was 0.77 +/- 0.43 for diastolic blood pressure and 0.70 +/- 0.39 for systolic blood pressure. CONCLUSION: The placebo effect observed with office blood pressure measurements does not occur with home blood pressure measurements. Expected treatment effect can alter a physician's blood pressure readings. The precision of measurements is greater with home blood pressure (there is a lower SD). Use of home blood pressure measurements increases the power of comparative trials, allowing one either to study fewer subjects or to detect a smaller difference in blood pressure.

[Epidemiology of myocardial infarction in France. One-year survival in the Usik study].

The initial phase of the epidemiological USIK study has recensed data concerning 2,563 patients admitted to hospital for acute myocardial infarction. The second phase of this study has documented the 1 year survival of 2,152 patients (84%). The population comprised 1,533 men and 619 women with a mean age of 67 years. Severe left ventricular dysfunction (LVEF < 35%) was observed in 18% of patients and clinical signs of cardiac failure were present in 35% of patients in the first 5 days of infarction. The mortality was 8.2% at 5 days, 13.2% at 28 days and 19.5% at one year. In multivariate analysis, the principal predictive factor of mortality at 1 year was age (RR = 1.06, p = 0.0001): the mortality increased by 6% per year of age. In survivors 5 days after the onset of infarction, the 1 year prognosis was significantly correlated with age (RR = 1.05, p = 0.0001) and with cardiac failure (LVEF: RR = 1.57, p = 0.0001) and Killip class (RR = 1.66, p = 0.0001). The prescription of an ACE inhibitor or a betablocker in the first 5 days of infarction was associated with a reduction in 1 year mortality of 27% (p = 0.04) and 37% (p = 0.01) respectively. In conclusion, this study has determined the features of patients admitted to the Intensive Care Unit for acute myocardial infarction in France and to identify the factors influencing 1 year survival.
