[Are the 1999 World Health Organization-International Society of Hypertension recommendations applicable to clinical practice?].

UNLABELLED: The aim of the 1999 WHO-ISH guidelines is to help the physicians in the management of hypertensive patients. The institution of antihypertensive treatment represents an important stage of this management sometimes at the detriment of lifestyle measures (non pharmacological treatments). OBJECTIVES: To evaluate if the 1999 WHO-ISH guidelines concerning the initiation of antihypertensive treatment are applied in a hypertension clinic. METHODS: Seventy hypertensive subjects never treated by antihypertensive drugs, aged 51 +/- 13 years, managed in daily hospitalization, were included in the study. According to their level of cardiovascular risk, we evaluated the concordance between the 1999 WHO-ISH guidelines and the clinical practice in term of institution of treatment. RESULTS: A concordance of 70% between the 1999 WHO-ISH guidelines and the clinical practice was observed (50/70 subjects) and a discordance in 30% of cases (20/70). Among the discordant subjects, the treatment was instituted in 65% of cases although it was not recommended. In contrast, in the remaining 35% of cases, lifestyle measures have been proposed although an antihypertensive treatment was recommended. The principal determinants of the discordance were the grade 2 of hypertension, the presence of 1 or 2 risk factors and an enhanced cardiovascular risk (> or = 3 risk factors). Neither age, nor gender were an explicative parameter of the observed discordance. CONCLUSIONS: The 1999 WHO-ISH guidelines concerning the initiation of antihypertensive treatment are more often applied in clinical practice. However, in some cases of grade 2 hypertension drug treatment is more often prescribed than recommended by guidelines, and not enough in the presence of numerous cardiovascular risk factors.

[What tests should be conducted for secondary arterial hypertension in hypertensive patients resistant to treatment?].

UNLABELLED: The aim of this study was to determine the prevalence of secondary hypertension in a population of refractory hypertension without initial clinical or biological findings suggesting identifiable causes of hypertension. METHODS: A survey included 200 consecutive hypertensive patients referred to hypertension specialists for refractory hypertension (BP > 140/90 mmHg on at least two antihypertensive drugs). Prior inclusion, the permanent elevation of blood pressure was confirmed by ambulatory monitoring. In each subject an extensive work-up was performed to detect a secondary cause for hypertension. RESULTS: An essential hypertension was confirmed in 61% of this cohort. A secondary hypertension was detected in 20% of the patients; 8.5% with a primary hyperaldosteronism, 8% with a reno-vascular hypertension and 3% with a nephropathy. Moreover, 18.5% had a low renin hypertension. Thus, 27% of these patients had an abnormality of the renin-aldosterone axis. CONCLUSION: Patients with refractory hypertension should be explored to detect secondary hypertension even without findings suggesting such causes. This additional diagnostic procedure must include at least renovascular investigations and plasma renin/aldosterone level determinations in appropriate conditions.

[Validity of the clinical prediction rule for the diagnosis of renal arterial stenosis in hypertensive patients resistant to treatment].

PURPOSE: To perform an external validation of the clinical prediction rule established by Krijnen et al. (Ann Intern Med 1998; 129: 705-11) designed to identify renal artery stenoses (RAS) in hypertensive patients. METHODS: We included 102 patients with a refractory hypertension treated with at least two antihypertensive drugs. All subjects had the research of RAS by renal angiography, or angio-computed tomography, or doppler ultrasound. Probability to detect RAS was calculated with Krijnen's algorithm (Pre-test probability) from the following parameters: age, smoking status, diffuse atherosclerosis, recent hypertension (< 2 y), obesity (BMI > 25), abdominal bruit, hypercholesterolemia (> 6.5 mmol/L), creatinine. ROC curves were plotted for each pre-test probability value. A "post-test probability" was obtained from the likelihood ratio calculated at each pre-test probability level. RESULTS: RAS prevalence in this population was 49%. Area under the ROC curve was 0.79 and Youden index was maximal for a pre-test probability of 15%. Maximal likelihood ratio was obtained for a pre-test probability of 46%. Table shows post-test probability as a function of pre-test probability obtained with Krijnen's algorithm. [table: see text] CONCLUSION: Krijnen's algorithm is valid in a population of resistant hypertensives treated with a bi-therapy. This external validation obtained on a population with a high prevalence of RAS should also be tested on a population with a lower prevalence of SAR.

[Treatment of arterial hypertension in the elderly].

The benefits of treating hypertension in the elderly have been demonstrated in therapeutic trials of patients over 60 years of age. In 1985, the EWPHE study, showing that thiazide diuretics decreased the risk of the main cardiovascular complications in elderly hypertensive patients, opened the field to the demonstration of the preventive efficacy of other classes of antihypertensive drugs. The high level of cardiovascular risk in the elderly explains why the prescription of antihypertensive agents provides a greater benefit in elderly rather than in young hypertensive patients. In the over 80 s', the benefits of lowering the blood pressure have been demonstrated in the prevention of non-fatal complications.

[Efficacy of and tolerance to prolonged release prazosin in patients with hypertension and non-insulin dependent diabetes].

UNLABELLED: The treatment of hypertension represents one of the major elements of the cardiovascular prognosis in type II diabetes. Among antihypertensive drugs, alpha blockers may be interesting because of the absence of unfavourable effects on plasma glucose and lipid levels. OBJECTIVE: The aim of this study was to evaluate the effectiveness and the safety of prazosin osmotic tablet treatment in non-insulin-dependent diabetic patients with mild to moderate arterial hypertension. METHODS: After an initial 4-week-single-blind placebo period, 81 hypertensive subjects (162 +/- 11/96 +/- 5 mmHg) with type II diabetes were included in the study to receive prazosin osmotic tablet (o.t) open-label therapy at the dose of 2.5 mg/day for 12 weeks. After 4 weeks of treatment the dosage of prazosin o.t was increased to 5 mg/day if the diastolic blood pressure remained > or = 90 mmHg. RESULTS: Both supine and standing systolic and diastolic blood pressures were significantly decreased (P < 0.001) with prazosin therapy from 162 +/- 10/96 +/- 5 mmHg in supine and 160 +/- 12/95 +/- 6 mmHg in the upright position, to 149 +/- 15/86 +/- 9 mmHg and 148 +/- 16/86 +/- 9 mmHg respectively at the end of the 12-week-treatment period. There were no significant changes in the glycemic parameters (glycemia, haemoglobin A1c) during the prazosin therapy compared with baseline values. A significant decrease of triglycerides (P = 0.005), total cholesterol (P < 0.001) and LDL cholesterol (P = 0.03) levels was observed during prazosin therapy compared with the baseline measurements, whereas HDL cholesterol remained stable. Only 6% of the patients reported adverse events in relation with the study drug during the active treatment period. CONCLUSION: This study showed a significant decrease of the blood pressure in hypertensive subjects with type II diabetes after prazosin o.t treatment, without any change of glycemic parameters. Moreover, there was a favourable evolution of the lipidic parameters during the study characterised by a significant decrease of triglycerides and total and LDL cholesterol.

[Management of patients with hypertension resistant to treatment].

A patient with a blood pressure greater than 140/90 mmHg under triple drug therapy, including a diuretic, has a resistant hypertension. Management mandates the following steps: to identify antihypertensive treatments previously prescribed (doses, efficacy, side effects); to evaluate blood pressure levels outside the medical office; to inquire about poor compliance; to search for secondary hypertension. In most cases, tailoring of treatments improves the care of such patients.

Validation of two devices for self-measurement of blood pressure by elderly patients according to the revised British Hypertension Society protocol: the Omron HEM-722C and HEM-735C.

BACKGROUND: The validation of self-measurement devices for clinical use by elderly patients has been recommended. The Omron HEM-722C device has recently been validated according to the British Hypertension Society (BHS) protocol for use for general populations and the Omron HEM-735C is a new fully automatic device with a high capacity for storage of measurements that is integrated with a personal computer. OBJECTIVE: To perform a clinical validation for use by elderly people of the Omron HEM-722C and HEM-735C devices according to the revised protocol of the BHS and the criteria of the Association for the Advancement of Medical Instrumentation (AAMI). METHODS: We carried out a main validation test according to the revised BHS protocol for validation procedures for special groups on two groups of 30 subjects aged more than 65 years (29 men and 31 women), 11 of 30 with systolic blood pressures (SBP) <110mmHg, 10 of 30 with SBP >200 mmHg, 15 of 30 with diastolic blood pressures (DBP( <70 mmHg and 10 of 30 with DBP >110 mmHg. The results were graded according to the BHS system from A to D. RESULTS: The Omron HEM 722C achieved an overall A/A grading and satisfied the AAMI criteria for accuracy whereas the Omron HEM-735C achieved an overall B/A grading and satisfied the AAMI criteria for accuracy. The sphygmomanometer measurements were 147 +/- 31/79 +/- 15 and 144 +/- 30/78 +/- 15 mmHg (means+/-SD) respectively, for the models 722C and 735C. The average differences between mercury sphygmomanometer and HEM-722C readings for SBP and DBP were, respectively, 0.76+/-5 and 0.41+/-8 mmHg; those for HEM-735C were, respectively, 0.24+/-8 and 0.9+/-8 mmHg. Readings of the HEM-722C device differed by less than 5 mmHg for 76% of systolic readings and 96% of the readings differed by less than 10 mmHg. Diastolic measurements differed by less than 5 mmHg for 71% and less than 10 mmHg for 71 and 87% of all readings. Readings of the HEM-735C device differed by less than 5 mmHg for 68% of systolic readings and 74% of the readings differed by less than 10 mmHg. Diastolic measurements differed by less than 5 mmHg in 74% and less than 10 mmHg in 88 and 87% of all readings. CONCLUSIONS: On the basis of these results, for elderly subjects both self-measurement devices (Omron HEM-722C and HEM-735C) satisfied the validation criteria of the BHS and therefore can be recommended for the clinical measurement of blood pressure in elderly patients.

The aging process modifies the distensibility of elastic but not muscular arteries.

Aging decreases the distensibility of large elastic arteries; however, the effects of age on the functional parameters of muscular, medium-sized arteries are not well determined. This study evaluated the consequences of aging on the functional parameters of the carotid and radial arteries in normotensive men. A total of 62 elderly subjects (aged 74+/-2 years) were compared with 87 young subjects (aged 35+/-3 years). Internal diameter and intima-media thickness (IMT) were measured by a high-resolution echo-tracking system to calculate distensibility and incremental elastic modulus (Einc). Although in the normal range, systolic and diastolic blood pressure levels were statistically different in the 2 groups at 128+/-19 and 74+/-13 mm Hg versus 121+/-27 and 71+/-18 mm Hg in the young and elderly subjects, respectively (P<0.05). At the carotid artery level, elderly subjects exhibited a greater IMT (742+/-144 versus 469+/-132 microm; P<0.01) and internal diameter (7067+/-828 versus 6062+/-1026 microm; P<0.01) than young subjects; elderly subjects also had lower distensibility (12+/-2 versus 21+/-2 kPa(-1) x 10(-3); P<0.01) and higher Einc (0.9+/-0.2 versus 0.7+/-0.3 kPa x 10(3); P<0.01). At the radial artery level, both IMT (240+/-42 versus 218+/-51 microm; P<0.01) and internal diameter (2685+/-432 versus 2491+/-444 microm; P<0.01) were greater in elderly subjects, but no differences in distensibility and Einc were observed between the 2 groups. All differences remained significant, even after adjusting for mean blood pressure. These results indicate that the increase of the internal diameter and IMT observed during the aging process can have opposite effects on the functional parameters of large elastic or medium-sized muscular arteries.

[Antihypertensive treatment can normalize the geometry and the arterial function in the aged patient].

The aging process and the elevation of arterial blood pressure (BP) have synergistic effects on the modifications of the arterial system. The effects of the treatment on these modifications are unknown. Our objective was to study the consequences of anti-hypertensive treatment on the geometry and function of the arteries in men over 70 years old. In 89 men aged 74 +/- 2 years, we measured internal diameter and intima-media thickness (IMT) of carotid and radial arteries using high resolution echography (WALL TRACK SYSTEM and NIUS-02), and carotid-femoral pulse wave velocity (PWV) by COMPLIOR. The BP was measured in supine position by Dinamap. In 28 subjects the BP was more than 140/90 mmHg (poor controlled hypertensives-HTpc); in the subjects where BP < 140/90 mmHg, 44 were normotensives (NT) without treatment and 17 were well controlled hypertensives (HTwc) on use of at least one antihypertensive. [table: see text] The PWV was increased in HTpc (20.1 m/s) in comparison with NT (14.6 m/s) and HTwc (16.1 m/s) (p < 0.05). The operational distensibility of radial artery was similar in the three groups. In conclusion, in elderly men aged more than 70 years, the anti-hypertensive treatment can normalize the functional properties and the geometry of muscular and elastic arteries. These results indicate that the arterial modifications observed in elderly hypertensives are consequence of the high blood pressure per se and not only consequent the modifications due to the aging.

[Feasibility and importance of self-monitoring in patients over 75 years old].

The feasibility of self-measurement (SM) of the blood pressure (BP) is well demonstrated in hypertensive patients (pts) but, in elderly pts physical and intellectual limitations can restrict the use of SM. The aim was to evaluate the feasibility of SM as a function of autonomic psychomotricity in pts aged more than 75 years and to estimate the reproducibility of SM in comparison with office's measurements (OM). We initially proposed the use of SM devices of BP to 53 pts aged > 75 years. One-third of pts refused to participate in the study. In 32 pts we did a mini-mental-state score (MMS) and an evaluation of autonomic functions (IADL). Two patients with a MMS < 20 were excluded. The OM of BP was done in sitting position with a mercury sphygmomanometer (4 measures) and the SM by a Omron device during 5 consecutive days (3 measures morning and night). Eighteen (60%) pts did more or equal to 15 measures (good measurer) and 12 less than 15 (bad measurer). The pts of the group "good measurer" were significantly younger, were all hypertensive treated patients and had a higher MMS and a lower IADL than those of the group "bad measurer". Considering the differences (OM-SM), 55% of patients showed values superior to 10 mmHg for systolic blood pressure, and 64% of subjects had values superior to 5 mmHg for diastolic blood pressure. We conclude that the SM is acceptable by patients older than 75 years and that feasibility is optimal in those patients where the autonomic and cognitive functions are preserved and when the patient is hypertensive. Also, as the concordance between OM and SM of patients older than 75 years is below 50%, diagnostic and therapeutic decisions based on OM is hazardous in these patients.

[Benefits of hypertension treatment in the elderly].

The benefits of treatment of hypertension in the elderly have been demonstrated by the results of therapeutic trials conducted in subjects over the age of 60. In 1985, the EWPHE trial, which demonstrated that thiazide diuretics decreased the main cardiovascular complications observed in elderly hypertensives, opened the way to the demonstration of the preventive efficacy of other classes of antihypertensives. The high level of cardiovascular risk observed in the elderly explains why prescription of antihypertensives provides a greater benefit in elderly hypertensives than in younger hypertensives. In hypertensive patients over the age of 80, the benefits of drug-induced blood pressure reduction have been demonstrated in terms of prevention of nonfatal complications.

Opposite effects of plasma homocysteine and the methylenetetrahydrofolate reductase C677T mutation on carotid artery geometry in asymptomatic adults.

Studies of symptomatic patients have identified hyperhomocysteinemia as an independent risk factor for vascular disease. In case-control studies, a point mutation (C677T) in the gene encoding 5,10-methylenetetrahydrofolate reductase (MTHFR) has also been linked to an increased risk of vascular disease through its effect on homocysteinemia. Our aim was to extend these observations to asymptomatic subjects by studying the influence of both homocysteinemia and its mutation on carotid artery geometry. We examined 144 subjects free of atherosclerotic lesions. Fasting homocysteinemia was measured by high-performance liquid chromatography with fluorometric detection. MTHFR genotype was analyzed by polymerase chain reaction followed by HinfI digestion. Carotid artery geometry was characterized by internal diameter and intima-media thickness, as assessed by a high-resolution echo-tracking system. Subjects in the upper homocysteine tertile had a greater carotid internal diameter than did subjects in the middle and lower tertiles (6516+/-770 versus 6206+/-641 and 5985+/-558 microm, respectively; P<0.001). Subjects homozygous for the mutation had a smaller carotid artery internal diameter than did subjects heterozygous or homozygous for the wild-type allele (5846+/-785 versus 6345+/-673 and 6199+/-671 microm, respectively; P<0.05). Homocysteinemia was not significantly increased in subjects homozygous for the mutation. In multivariate regression analysis, homocysteinemia was independently and positively associated with lumen diameter (P=0.0008) and wall thickness (P=0.020). Conversely, homozygosity for the mutation was negatively associated with internal diameter (P=0.009). These preliminary data suggest that mildly elevated homocysteinemia and homozygosity for the MTHFR C677T mutation are associated with opposite preclinical modifications of carotid artery geometry. If confirmed, these results may have important implications for new treatment strategies for vascular disease before the onset of clinical manifestations.

Lack of association between renin-angiotensin system, gene polymorphisms, and wall thickness of the radial and carotid arteries.

To investigate the relationship between polymorphisms of the angiotensin-converting enzyme (ACE) and the angiotensin II type 1 receptor (AT1R) genes and structural phenotypes of arteries, we studied a cohort of 340 subjects (aged 49+/-12 years) without evidence of cardiovascular disease and who had never been treated previously with any cardiovascular treatments. Structural phenotypes (wall thickness and internal diameter) were evaluated for the common carotid and the radial arteries using high-resolution echo-tracking devices (NIUS-02 and Wall Track System). The influence of ACE insertion/deletion (I/D) and AT1R A/C1166 polymorphism genotypes on structural parameters was tested by ANOVA and logistic regression analysis. For the radial artery, mean wall thickness among subjects according to the ACE I/D or AT1R A/C1166 genotypes was not different. This lack of association persisted in a logistic regression analysis or when the comparison was restricted to a subgroup of subjects potentially at high genetic risk (DD and CC or AC) compared with subjects at low genetic risk (AA and II or ID). Also, no association was observed between the carotid artery intima-media thickness and the 2 polymorphisms. In conclusion, the ACE I/D and the AT1R A/C1166 gene polymorphisms are not markers of vascular hypertrophy in subjects with no evidence of cardiovascular disease. These results suggest that these gene polymorphisms have an undetectable role in the geometry of the radial and carotid arteries compared with usual determinants such as blood pressure and age.

[Assessment of antihypertensive compliance using a self-administered questionnaire: development and use in a hypertension clinic].

OBJECTIVE: The most practical method of assessing medication compliance is to ask the patient for a self-report; but the interview question has to be selected and validated. The aim of this work was to select and validate interview questions to be used in a self-administered questionnaire for measurement of medication compliance in hypertensive patients. PATIENTS AND METHODS: In 117 treated hypertensive patients, we compared an interview question to a clinical evaluation of medication compliance. Kappa indices were calculated to test the concordance between interview question and medication compliance. In 184 patients treated for hypertension since at least a year, the validated self-report was compared to a clinical evaluation of medication compliance. RESULTS: Interview questions were not equally sensitive for detection of medication compliance and 6 questions were included in the Compliance Evaluation Test (CET). In 184 patients, we compared the results obtained with CET to clinical evaluation of medication compliance. Values of kappa indices were above 0.5 in "good compliance" when "No" was answered to the 6 items, in "minor noncompliance" when 1 or 2 "Yes" were given, in "noncompliance" when 3 or more "Yes" were given. In this population of hypertensive patients followed in a hypertension clinic, we observed 10% "noncompliance", 24% "minor noncompliance", and 66% "good compliance". CONCLUSION: In clinical practice, interview may be the most useful method of measuring medication compliance. We demonstrated that the compliance evaluation test is validated and may help physicians to face the problem of nonadherence among their hypertensive patients.

[Sexual dysfunction in treated hypertensive patients. Results of a national survey].

OBJECTIVES: To evaluate, using an self-administered questionnaire, the characteristics of sexual function in treated hypertensives. METHODS: In 459 hypertensive subjects, aged of 59 +/- 12 years, living in France and referred to hypertension specialists, a self-administered questionnaire evaluating quality of life and antihypertensive treatment was given before the consultation. Several questions focused on the quality of sexual function since the last 12 months (interest for sexuality, sexual pleasure, quality of erection). Details on antihypertensive treatments and cardiovascular characteristics were obtained from medical records. Antihypertensive treatments were prescribed since more than 10 years for 39% of subjects, since 5-10 years for 25%, since 1-5 years for 26%, and since less than 1 year for 10%. RESULTS: In this population of treated hypertensives, blood pressure level was higher in men than in women (145 +/- 22/86 +/- 13 vs 135 +/- 25/76 +/- 15; p < 0.01). In the questionnaire, the section with sexual function questions was filled out extensively in 92% of men (248/268), but only in 74% of women (142/191). Sexual disturbance was declared by 38% of cases (148/390), but rate was significantly higher in men as compared to women (49% vs 18%; p < 0.01). In men, these modifications were characterised by an interest for sexuality decreased for 58%, unchanged for 41% and increased for 1%. Sexual pleasure was decreased for 49%, unchanged for 50%, and increased for 1%. Quality of erection was modified in 45%. The erections were less frequent for 31%, less durable for 19% and impossible for 11%. In women, interest for sexuality was decreased for 41% and unchanged for 59%, sexual pleasure was decreased for 34% and unchanged for 66%. Logistic regression analysis indicates that gender (p < 0.001), greater number of antihypertensive tablets (p < 0.01), prescription of diuretics (p = 0.03) and presence of coronaropathy (p = 0.01) were independent determinants for sexual disturbance in treated hypertensives. CONCLUSION: This study indicates that sexual disturbance is declared by 38% of patients treated for hypertension. Because complaints are more frequent in men, treated with multiple medications including a diuretic, a specific interrogation should be proposed more regularly in these patients in order to detect and to deal with, if possible, sexual disability.

[Study of the effect of season on the frequency of side effects or antihypertensive agents].

OBJECTIVES: To evaluate the influence of season on side effects of antihypertensive treatments in hypertensive patients followed by cardiologists. METHODS: In 12,071 hypertensive subjects, referred to cardiologists, a questionnaire with 14 possible side effects due to antihypertensive treatment was administered during the consultation. Details on antihypertensive treatment and cardiovascular characteristics were obtained from medical records. This evaluation was obtained in patients recruited during summer (7,438 patients) and during winter (4,633 patients). RESULTS: In this population of treated hypertensives, blood pressure level was < 140/90 mmHg in 28%, and 50% were treated with a monotherapy. At least one side effect was declared by 40% of cases, and it was observed dyspnea (10%), dizziness (8%), fatigue (8%), palpitations (6%), ankle oedema (5%), headaches (5%). The higher rate was observed in patients on monotherapy, most frequent side effects were fatigue (9%) on beta-blockers, cough (9%) on ACEI, oedema (18%) on calcium antagonists, dyspnea (9%) on diuretics, dizziness on ARB (8%) and central acting agents (18%). Regression analysis indicates that female patient, uncontrolled BP, age less than 50, and greater number of antihypertensive tablets were independent determinants for at least one side effects under antihypertensive treatments. Season was not a significant determinant of side effect appearance. CONCLUSION: This study indicates that during hypertensive treatments, at least one side effect is declared by 40% of patients. A female patient, uncontrolled for BP, aged less of 50 and treated with a multiple therapy is more prone to complain of side effects, but season was not a significant determinant of its appearance.

[Rational choice for second antihypertensive agent after failure of the first monotherapy: therapeutic strategy].

This study evaluated a strategy to treat naive hypertensive patients, based on a single monotherapy followed, in uncontrolled patients, by a rationale choice for the second antihypertensive treatment. Subjects with essential hypertension, entered into the study if their BP measured with an OMRON 705CP was > 140/90 mmHg on two separate visits. Patients were allocated to single treatment in a balanced randomized design to receive either a "group 1" treatment (ACE inhibitor, beta-blocking drug or ARB) or a "group 2" treatment (calcium channel-blocking drug or thiazide diuretic). After one month of treatment at a standard dose, if BP was > 140/90 mmHg, first adaptation was a fixed combination therapy with one drug from "group 1" and one drug from "group 2". At 3 months, patients with BP < 140/90 mmHg were considered to have reached BP goal. Forty-eight patients entered the study with a mean age of 53 +/- 11 years. Initial SBP/DBP (mmHg) was 164 +/- 16/97 +/- 8. After 1 month, 40% achieved the target BP, 52% were uncontrolled with no side effects and 8% were uncontrolled and had side effects. After 3 months, 84% achieved BP goal and a fixed combination therapy was prescribed in 52% of the controlled patients. The initial monotherapy was maintained alone or in combination in 70% of the controlled patients. A strategy based on a single monotherapy followed, if necessary, by a rational choice for the second treatment in a fixed combination therapy is effective to achieve BP control in 84% of naive hypertensive patients.

[Application of French guidelines in newly diagnosed hypertensive patients managed by general practitioners].

UNLABELLED: The French guidelines of the 2000 ANAES indicate that the management of patients with hypertension should not be based only on the level of blood pressure, but also on the presence of other risk factors and/or concomitant diseases such as diabetes or target organ damage. OBJECTIVES: To evaluate if the 2000 ANAES Guidelines concerning the initiation of antihypertensive treatment are applied by general practitioners. METHODS: Seventy new diagnosed hypertensive subjects, never treated by antihypertensive drugs, managed by 13 general practitioners were included in the study. From the data of the general practitioners medical report, the cardiovascular risk have been retrospectively recalculated for all the subjects. The concordance between the Guidelines and the clinical practice in term of institution of treatment have been evaluated. RESULTS: In this population of mean age 58 +/- 15 years, a concordance of 64% between the 2000 ANAES Guidelines and the clinical practice was observed (45/70 subjects). Among the discordant subjects (36%, [25/70]), the treatment was instituted by excess in 88% of cases (22/25) although it was not recommended. In contrast, in the remaining 12% of cases, only lifestyle measures have been proposed although an antihypertensive treatment was recommended. The discordance concerns essentially subjects with medium cardiovascular risk (84%). The principal determinants of this discordance were the grade 2 of hypertension and the presence of few risk factors (1 or 2), where the cardiovascular risk have been overestimated. CONCLUSIONS: Guidelines concerning the initiation of antihypertensive treatment in new diagnosed hypertensive subjects are more often applied by general practitioners. It is particularly in subjects with medium cardiovascular risk that the decision of the initiation of treatment is taken by excess in comparison to guidelines.
