A novel prognostic index to determine the impact of cardiac conditions and co-morbidities on one-year outcome in patients with heart failure.

Prognostic stratification is relevant in clinical decision making in heart failure (HF). Predictors identified during hospitalization or in clinical trials may be unrepresentative of HF in the community. The aim of this study was to derive and validate, in different clinical settings, a risk stratification model for the prediction of stable HF outcomes. The study included 807 patients, 350 enrolled at discharge from the hospital (44%), 309 in the outpatient clinic (38%), and 148 in the home-care setting (18%). There were 292 patients in the derivation cohort and 515 in the validation cohort. A multivariate logistic analysis was performed to obtain the CardioVascular Medicine Heart Failure (CVM-HF) index. One-year mortality was 20.8% in the derivation cohort and 20.7% in the validation cohort. The CVM-HF index included cardiac conditions and co-morbidities and stratified the 1-year mortality risk as low (death rate 4%), average (32%), high (63%), and very high (96%). The area under the curve of the receiver-operating characteristic curve was 0.844 (95% confidence interval [CI] 0.779 to 0.89) for the derivation cohort and 0.812 (95% CI 0.76 to 0.86) for the validation cohort. Model performance was equally good in the 3 different HF settings. In a subgroup of 409 patients, the CVM-HF index (area under the curve 0.821, 95% CI 0.79 to 0.89) outperformed the most-used prognostic models (the Charlson index and the Heart Failure Risk Scoring System). In conclusion, the CVM-HF index, a novel prognostic model that is easy to derive and applicable to unselected patients, may represent a valuable tool for the prognostication of stable HF outcomes.

Secondary prevention of myocardial infarction: a survey in primary care.

OBJECTIVE: To collect information on the major risk factors and secondary prevention among patients with myocardial infarction in Italy. METHODS: Data were obtained from the database of the Italian College of General Practitioners; 3588 patients (mean age 68.7 +/- 11.3 years; 2698 men, 888 women; two unrecorded gender), with an average time from event of 6 +/- 5.7 years, were identified. RESULTS: Among the major risk factors, data entry ranged from 50.3% for physical activity to 74.9% for blood pressure. Inadequate blood pressure control was present in 49.2% and elevated plasma cholesterol levels (> 5.2 mmol/l) in 57.3%; among the latter group, 65% were on lipid-lowering therapy. Only 47.2% of the treated patients achieved a total cholesterol level of < 5.2 mmol/l. Antiplatelet or anticoagulant drugs, beta-blockers, and angiotensin-converting enzyme inhibitors were prescribed to 43%, 10.3%, and 57.9% of patients, respectively. CONCLUSIONS: The preventive attitude of Italian general practitioners is similar to that reported in other European countries with two noticeable exceptions: under-prescription of beta-blockers and of antiplatelet drugs. Clearly, secondary prevention requires major improvement.

[Assessment of the absolute global cardiovascular risk: comparison between the risk chart and the individual score of the CUORE Project].

BACKGROUND: To evaluate 10-year cardiovascular risk, the risk chart and the individual risk score from the CUORE Project were recently introduced in Italy. These tools differ as for age range and some risk factors. Therefore, the aim of this study is to evaluate the difference between the global absolute risk assessed by the risk chart and the individual risk score using the data collected through the Osservatorio Epidemiologico Cardiovascolare (OEC). METHODS: From the Osservatorio Epidemiologico Cardiovascolare sample, 6508 people aged 40-69 years without clinical manifestations of atherosclerosis were selected. Cardiovascular risk was assessed using risk chart and individual risk score and the 10-year risk was categorized in six classes (< 5%, 5-9%, 10-14%, 15-19%, 20-29%, > or = 30%). As coefficient of agreement between risk chart and individual risk score, Cohen kappa statistic was computed using the Cicchetti-Allison weights (k(w)). RESULTS: From contingency tables of the two methods distribution, k(w) was 0.71 (p < 0.0001 and 95% confidence interval 0.70-0.72). Using the 20% risk threshold reported in Nota 13 of Agenzia Italiana del Farmaco and excluding persons who were treated for hyperlipemia refunded regardless of their chart or individual score estimation of cardiovascular risk, the differences between the two tools classification resulted in the 2.6% of the sample (1.4% were assessed as at non-high risk [< 20%] using the risk chart and at high risk using the individual risk score, and the opposite for 1.2%). CONCLUSIONS: Classification difference between risk charts and the individual risk score is quite small. Updating of predictive functions of two tools could improve their concordance also for individual evaluation, including older people and better reflecting current Italian lifestyle.

Patterns of persistence with antihypertensive medications in newly diagnosed hypertensive patients in Italy: a retrospective cohort study in primary care.

OBJECTIVE: To describe patterns of persistence and related primary care costs associated with first antihypertensive treatment. DESIGN AND SETTING: Retrospective cohort study during 2000-2001, using information from 320 Italian general practitioners. PARTICIPANTS: We studied 13 303 patients with newly diagnosed hypertension, who received a first single antihypertensive prescription within 3 months after diagnosis. MAIN OUTCOME MEASURES: Persistence with first-line single treatment, categorized as follows: continuers: patients continuing the first-line medication for at least 1 year; combiners: patients receiving an additional antihypertensive drug and continuing the initial medication; switchers: patients changing from the first-line to another class of antihypertensive drug and discontinuing the initial treatment; discontinuers: patients stopping the first-line treatment without having another prescription until the end of the follow-up. Primary care costs were expressed as the cost of hypertension management per person-year of follow-up. RESULTS: In the study cohort, 19.8% were continuers, 22.1% were combiners, 15.4% were switchers, and 42.6% were discontinuers. Continuation was greatest with angiotensin II type 1 receptor blocking agents (25.2%), calcium channel blockers (23.9%) and angiotensin-converting enzyme inhibitors (23.3%). Severe hypertension [hazards ratio 1.30; 95% confidence interval (CI) 1.18 to 1.43] and severe health status (hazards ratio 1.22; 95% CI 1.15 to 1.30) increased the risk of discontinuation. The likelihood of needing an additional antihypertensive drug was associated with mild-to-severe baseline blood pressure, diabetes (hazards ratio 1.20; 95% CI 1.06 to 1.36), and familial history of cardiovascular disease (hazards ratio 1.24; 95% CI 1.10 to 1.39). Discontinuers accounted for 22.4% of the total primary care cost. Initial treatment with angiotensin II type 1 receptor blocking agents and beta-blockers resulted in incremental primary care costs of 145.2 and 144.2, respectively, compared with diuretics. Combiners and switchers increased the primary care cost by 140.1 and 11.7, compared with continuers. CONCLUSION: Persistence with first-line single antihypertensive drugs is extremely low during the first year of treatment. Potential cost saving should be possible by reducing the high frequency of discontinuation. Diuretics represent the least expensive therapeutic option, although further investigations in the long-term are needed to analyse the effects of persistence on therapeutic effectiveness and related costs.

Cholesterol control in stroke prevention in Italy: a cross-sectional study in family practice.

BACKGROUND: Stroke represents worldwide the second and seventh cause of death and invalidity, respectively. Patients with ischaemic stroke or transitory ischaemic attack (TIA) are at high risk of recurrence, therefore requiring intensive treatment. Hypercholesterolaemia is a modifiable risk factor for stroke. The general practitioners attitude towards detection and treatment of dyslipidaemia among patients with stroke or TIA in Italy is unknown; we therefore aimed to address this issue taking advantage of the database of The Italian College of General Practitioners. METHODS: Prevalence of the monitored factors (lipid levels, statin prescription, and lipid level control with hypolipidaemic agents prescription) were analysed on a patient population of 465 061. RESULTS: A total of 2555 (49% women and 51% men) patients with a diagnosis of stroke and 2755 patients (52% women and 48% men) with a diagnosis of TIA were included in the study. Total plasma cholesterol (TC) was reported in more than 60% of the patients and low-density lipoprotein cholesterol (LDLc) and high-density lipoprotein cholesterol (HDLc) in less than half. Total plasma cholesterol and LDLc were controlled in 70.3 and 72.8% of the patients, respectively. The percentage of controlled patients decreased to 64% when both LDLc and TC were considered. Statins and fibrates were prescribed in a small proportion of patients (16.9 and 3.5%, respectively). An acceptable control of blood lipids was achieved in a majority of those patients (60.2%). However a relatively large number of patients (646) with high plasma lipids remained untreated. CONCLUSIONS: Monitoring and intervention strategies on plasma lipid levels in patients with a diagnosis of stroke or TIA need to be improved.

Computerized general practice databases provide quick and cost-effective information on the prevalence of angina pectoris.

BACKGROUND: The aim of this study was to compare the prevalence of angina pectoris (AP) using self-reported information and primary care databases. METHODS: A comparison between the prevalence of AP in 730,586 subjects from the Health Search Database (HSD) and 119,799 individuals from a Health Interview Survey (HIS) was performed. The age-specific prevalence was calculated by dividing the detected cases by the total number of individuals in each age group. The age-standardized prevalence was estimated by direct standardization performed using the Italian standard population. RESULTS: The HSD reported a higher crude prevalence of AP than the HIS, both in males (1374/100,000 vs 1006/100,000) and females (1449/100,000 vs 1007/100,000). In the HSD the age-specific prevalence was lower for patients aged <65 years, whilst higher estimates were reported for older patients. Age standardization slightly reduced the prevalence in both samples, although the HSD always reported higher estimates. CONCLUSIONS: Prescription data from general practice databases may be a valid, simple, and cost-effective method to evaluate and serially monitor the prevalence of AP.

The database of Italian general practitioners allows a reliable determination of the prevalence of myocardial infarction.

BACKGROUND: To plan preventive intervention after myocardial infarction (MI) the disease prevalence and the age and time from acute event of the index population should be known. METHODS: We identified all the living patients with MI coded diagnosis in the database of the Italian College of General Practitioners (Health Search Database-HSD). The years from the first acute MI were also determined. RESULTS: 3588 subjects with MI diagnosis were identified (2698 males and 888 females, for 2 gender not recorded). Based on the distribution of our population and on that reported by the Italian Institute of Statistics, stratified by gender and age (segments of 10 years), the estimated number of subjects with MI in Italy (age-standardized rates x 10000) was 309284 for men and 102343 for women. CONCLUSIONS: The prevalence of MI diagnosis in the HSD is very close to that obtained by other epidemiological methods. Querying the database can provide a simple and inexpensive way to estimate and monitor the prevalence of MI in Italy.

Homecare for patients with heart failure in Italy.

UNLABELLED: BACKGROUND; Heart failure (HF) represents an important health issue in western countries, especially for the elderly, frail population. A number of HF patients must usually be assisted at home. No information is available about the usual care of HF patients in Italy. The aim of this study was to describe the characteristics of HF patients receiving homecare in the Italian general practice. METHODS: A questionnaire was sent to 320 general practitioners (GPs) involved in the Health Search project. Among these, 148 (46.2%) answered and 376 home-ridden HF patients (60.3% women, median age 85 years) were identified. RESULTS: 257 (57%) patients were in NYHA class III or IV. Multiple relevant concomitant diseases occurred in 326 (86.7%) subjects. Only 140 (37.2%) patients were able to take their pills without any help; caregivers, mainly family members, were required 24 hours a day in 78.7% of cases. The length of homecare was > 1 year in 84.5% of cases. CONCLUSIONS: According to our data, thousands of HF patients are usually assisted at home for long periods in Italy. This is a very old group of subjects with heavy co-morbidity and a high need for continuous, prolonged assistance. Studies specifically aimed at the care of HF patients are needed.

Oral anticoagulant therapy in Italy: prescribing prevalence and clinical reasons.

BACKGROUND: Oral anticoagulants (OAs) are recommended for many clinical problems and their use requires organised and knowledgeable medical support. Up to our knowledge, there is no data about both the reasons of treatment among OAs' users and the number of patients prescribed with OAs in Italy. OBJECTIVES: To describe the OA use, and the reasons of prescribing among Italian General Practitioners. METHODS: We used the Health Search Database owned by the Italian College of General Practitioners to identify the clinical records of patients > or =20 years who had at least one prescription of OAs during the year 2002. RESULTS: Among a study population of 448,495 patients, 3,649 subjects (0.81%) had received at least one OAs prescription. Applying such a proportion to the overall Italian population, on the basis of data from Italian Office for National Statistics (ISTAT), we estimated that 376,882 patients would have used OAs during the year 2002 in Italy. The most frequent clinical problem related to the use of OAs was atrial fibrillation (45.6%), followed by cardiac valve disease (14.6%), deep vein thrombosis (12.2%) and peripheral artery embolism (7.7%). CONCLUSIONS: Approximately 370,000 patients are prescribed with OAs in Italy and for more than 50% of them life-long therapy is recommended. Atrial fibrillation is the most frequent reason for prescription.

Global cardiovascular risk evaluation in Italy: a cross-sectional survey in general practice.

BACKGROUND: The aim of our work was to evaluate, in a general practice setting, the attitude of general practitioners in determining the individual coronary risk. METHODS: The coronary risk was determined among patients aged 30 to 74 years using the following parameters: gender, age, smoking habits, diagnosis of diabetes mellitus, systolic blood pressure, and total cholesterol. We evaluated the records of 446,331 subjects collected by 481 general practitioners working throughout Italy. RESULTS: Except for age, gender and diabetes mellitus, risk factors were largely under-recorded: blood pressure in 37.0% of the total patients, total cholesterol in 34.3%, smoking habits in 21.9%. Recording was substantially low even in patients who were prescribed with antihypertensive drugs and/or lipid-lowering drugs: blood pressure in 80.6% of the patients, total cholesterol in 69.1%, smoking habits in 46.1%. Cardiovascular risk factors were more frequently recorded as age increased and slightly more among women as compared to men. Obviously, it is possible that risk factors had been assessed but not recorded. CONCLUSIONS: Cardiovascular risk factors are substantially under-recorded among Italian general practitioners thus impairing adequate preventive treatment. A systematic, well programmed approach may theoretically lead to evaluate the majority of the target population within a few years.

Management of patients with suspected angina, but without known myocardial infarction: a cross-sectional survey.

BACKGROUND: Although several studies describing the diagnostic and therapeutic management of patients with myocardial infarction (MI) by general practitioners have recently been published, little information exists about patients with angina without MI. AIM: To describe the management of patients with angina without known MI in general practice. DESIGN: A cross-sectional survey. SETTING: Italian general practitioners providing data to the Health Search Database. METHOD: Prevalent cases of angina, using the prescription of nitrates as a 'proxy' for disease status, in patients without known MI were selected from the Health Search Database. Data on patient demographics, clinical information, established therapies and cardiology visits were collected. A binomial logistic regression analysis was performed to test which variable made prescription more or less likely. RESULTS: There were 10 455 patients with angina. Blood pressure readings were available for 73.8% of patients; in this group 58.9% had inadequate (> or = 140/90 mmHg) blood pressure control. Total cholesterol was recorded in 61.6% of cases (mean value = 5.5 mmol/L). Antiplatelet or oral anticoagulant agents were used by 67.8% of the patients, while 24.1% of patients received lipid-lowering agents, 61% received ACE-inhibitors or angiotensin-II receptor antagonists, and 25.2% received beta-blockers. CONCLUSIONS: In patients treated with nitrates the monitoring of modifiable risk factors and the use of preventive drugs is lower than expected. New strategies aimed at improving secondary cardiovascular prevention among these easily identifiable high-risk subjects are needed.

Secondary prevention of stroke in Italy: a cross-sectional survey in family practice.

BACKGROUND: Hypertension control and antiplatelet or oral anticoagulant drugs are the basis for secondary prevention of cerebrovascular events. Family physicians (FPs) are usually involved in both aspects of prevention, but no research has been carried out in Italy to evaluate the behavior of FPs in this field of prevention. METHODS: Data concerning 318 Italian FPs and 465,061 patients were extracted from the Health Search Database. Patients with coded diagnoses of stroke and transient ischemic attack (TIA) were selected. Demographic records and information regarding presence of concurrent disease and medical records were also obtained. Logistic regression analyses were carried out to assess whether conditions exist that make appropriate control of blood pressure (BP) and prescription of antiplatelet or anticoagulant drugs more likely. RESULTS: We selected 2555 patients with diagnosis of stroke and 2755 with TIA. Among all of the subjects, 32.6% had no BP recorded. Among the remaining subjects, 58.7% reported uncontrolled BP. Isolated systolic hypertension has been shown in 68.8% of patients with uncontrolled BP. Antiplatelet and anticoagulant drugs were prescribed in 72% of these cases. Factors that made the prescription significantly more unlikely were diagnosis of TIA (odds ratio [OR], 0.47; 95% confidence interval [CI], 0.41 to 0.54), total invalidity (OR, 0.66; 95% CI 0.56 to 0.78), and time from event of 5 years or more (OR, 0.81; 95% CI, 0.70 to 0.94). CONCLUSIONS: Italian FPs could improve secondary prevention of cerebrovascular accidents. The primary target of intervention should be the control of systolic BP, and the group of patients with unacceptably high BP should be given priority. All of these patients should have been prescribed antiplatelet drugs or anticoagulant agents, except in cases of extremely short life expectancy or substantial contraindications.

Effects of an automated electronic reminder in changing the antiplatelet drug-prescribing behavior among Italian general practitioners in diabetic patients: an intervention trial.

OBJECTIVE: To evaluate whether an electronic reminder integrated into a routine computer system increases the use of antiplatelet drugs for diabetic patients among Italian general practitioners (GPs). RESEARCH DESIGN AND METHODS: A randomized controlled trial was carried out among 300 GPs and their patients selected from the Health Search Database. Among these, 150 GPs (intervention group) received instructions to activate an electronic reminder plus a letter summarizing the beneficial effects of antiplatelet drugs in diabetic patients with at least one additional cardiovascular risk factor ("high risk"), whereas the other 150 GPs (control group) received only the letter. The electronic reminder, integrated into a standard software system for the management of the daily clinical practice, was displayed when every participating GP opened the medical record of diabetic patients aged > or =30 years. Only high-risk diabetic patients were included in the analysis. Patients were considered under antiplatelet treatment if they received two or more prescriptions at baseline and during the follow-up. RESULTS: We selected 15,343 high-risk diabetic patients, 7,313 belonging to GPs of the control group and 8,030 belonging to GPs of the intervention group. Overall, 1,672 patients (22.9%) of the control group and 1,886 (23.5%) patients of the intervention group received antiplatelet drugs at baseline (P = N.S.). At the end of the follow-up, the number of treated patients was significantly increased in the intervention group (odds ratio 1.99, 95% CI 1.79-2.22) versus the control group. The effect of the electronic reminder was more relevant among those patients with one or more cardiovascular risk factors but without previous cardiovascular diseases (CVDs), compared with those with CVDs. CONCLUSIONS: These findings provide evidence for the effect of an electronic reminder in affecting the prescriptive behavior of GPs.
