Abstract: The present article reviews the epidemiological and statistical bases of the multivariate prediction of cardiovascular events and its transformation into practical tools for primary prediction. The problems with the use of tools derived from studies conducted in populations that are different from those in which the estimate is being made are documented. A description is made of a number of predictive tools produced in the past and recently included in risk manuals, charts and computer programs and their main characteristics are outlined. The problems in the origin, structure and use of the chart suggested by the Task Force of three European Scientific Societies, including the marked overestimate of the risk when this tool is applied to Italian data, are reviewed in detail. The need to use predictive tools derived from Italian population studies is stressed. Comments are made on the difficult choice between the use of the absolute and relative risks for the identification of high-risk subjects to be treated on an individual basis for primary prevention of major cardiovascular diseases.

Abstract: OBJECTIVE: Our aim was to compare the effect of lacidipine and chlorthalidone on cardiovascular outcome as a primary parameter and blood pressure as a secondary in elderly patients with isolated systolic hypertension in a prospective study with an open design. METHODS: 1882 males and females outpatients > or = 60 years were randomly assigned to the administration of chlorthalidone 12.5 mg o.d. or lacidipine 4 mg o.d. Patients were recruited if sitting systolic blood pressure was > or = 160 mmHg with a diastolic blood pressure equal or lower than 95 mmHg. Primary endpoint was a composite of cardiovascular and cerebrovascular events. RESULTS: At randomization mean systolic blood pressure was 178.1 mmHg in the lacidipine and 178.2 mmHg in the chlorthalidone group, the corresponding mean diastolic values being 86.9 and 86.8 mmHg. In both lacidipine and chlorthalidone groups treatment caused a significant (p < 0.001) and marked systolic blood pressure reduction which was maintained throughout the treatment period with a significant (p < 0.001) and steady although less marked reduction in diastolic blood pressure as well. At the end of treatment period (median 32 months), the reduction was 36.8/8.1 mmHg (systolic/diastolic) in the chlorthalidone and 38.4/7.9 mmHg in the lacidipine group, the final on treatment blood pressures being 142.0/79.2 and 143.2/79.5 mmHg, respectively. Treatments were similarly effective in males and females and in age groups between 60 and 69 years (n = 763), 70 and 79 years (n = 744) and > or = 80 years (n = 375). Similar reductions were obtained in a subgroup of patients (n = 209) followed in double-blind fashion for 1 year. The overall incidence of the primary endpoints was 9.3% with no significant between-group difference. Total mortality was also similar between groups. CONCLUSIONS: In elderly patients with isolated systolic hypertension, administration of lacidipine or chlorthalidone markedly reduced systolic blood pressure with no difference in the incidence of cardiovascular events and total mortality.

Abstract: BACKGROUND: Urinary albumin excretion (UAE) and estimated glomerular filtration rate (eGFR) have been used separately to provide information about cardiovascular risk. We analyzed whether UAE and eGFR used together provide complementary information. METHODS: We analyzed UAE, eGFR, cardiovascular risk factors, and incidence of cardiovascular disease in 1665 men and women of the Gubbio Population Study (aged 45-64 years). We designated UAE in the highest decile as high (>or= 18.6 microg/min in men and >or= 15.7 microg/min in women) and eGFR in the lowest decile as low (<64.20 mL/min/1.73 m(2) in men and <57.90 mL/min/1.73 m(2) in women). RESULTS: Kidney dysfunction defined using both markers was more frequent than using 1 marker (UAE alone or eGFR alone) (P< .001) because high UAE and low eGFR clustered in different individuals and were weakly associated with each other (P= .12). The hazard ratio (HR) for incident cardiovascular disease was elevated for both markers, independently of each other (HR for high UAE, 2.15; 95% confidence interval [CI], 1.33-3.49; HR for low eGFR, 2.14; 95% CI, 1.32-3.48). Kidney dysfunction defined by both markers predicted cardiovascular disease independently of sex, age, hypertension, hypercholesterolemia, smoking, diabetes mellitus, prior cardiovascular disease, left ventricular hypertrophy, and obesity (HR, 1.50; 95% CI, 1.05-2.14). The discriminant power of dysfunction defined by both markers was statistically significant (area under the receiver operating characteristic curve, 0.569 [P= .02]) and slightly higher than what was found with 1 marker of diabetes mellitus, prior cardiovascular disease, left ventricular hypertrophy, and obesity. CONCLUSIONS: High UAE and low eGFR provide complementary information in defining kidney dysfunction because they cluster in different individuals. Concomitant evaluation of both markers should be considered to adequately assess kidney dysfunction and cardiovascular risk.

Abstract: BACKGROUND: Blood pressure (BP) control is reported to be poor in hypertensive patients worldwide. OBJECTIVE: BP levels, the rate of BP control, prevalence of risk factors and total cardiovascular risk were assessed in a large cohort of hypertensive patients, derived from recent surveys performed in Italy. METHODS: Fifteen studies on hypertension, performed in different clinical settings (general population, general clinical practice, specialist outpatient clinics and hypertension centres) over the past decade were considered. RESULTS: The overall sample included 52 715 hypertensive patients (26 315 men and 26 410 women, mean age 57.3 +/- 6.9 years). Despite the high percentage of patients on stable antihypertensive treatment (n = 36 556, 69%), mean systolic and diastolic BP levels were 147.8 +/- 8.5 and 89.5 +/- 5.2 mmHg, respectively. On the basis of the nature of the study (population surveys or clinical referrals), systolic BP levels were consistently higher than the normality threshold in both settings (142.6 +/- 12.4/84.8 +/- 3.7 mmHg and 150.4 +/- 4.6/91.9 +/- 4.1 mmHg, respectively). The BP stratification could be assessed in 40 829 individuals: 4.5% had optimal, 9.2% normal and 8.3% high-normal BP levels, however, the large majority were in grade 1 (39%) or grades 2-3 (32.6%) hypertension. In the overall sample, 55.9% of hypertensive patients had hypercholesterolemia, 28.7% were smokers, 36.4% were overweight or obese and 15.0% had diabetes mellitus. Cardiovascular risk stratification was assessed in 37 813 hypertensives: 23.2% had low, 33.9% moderate, 30.2% high and 12.7% very high added risk. CONCLUSION: Our analysis demonstrates the persistence of poor BP control and high prevalence of risk factors, supporting the need for more effective, comprehensive and urgent actions to improve the clinical management of hypertension.

Abstract: BACKGROUND AND AIM: The need to update tools for the estimate of cardiovascular risk prompted the "Gruppo di Ricerca per la Stima del Rischio Cardiovascolare in Italia" to produce a new chart and new software called Riskard 2005. METHODS AND RESULTS: Data from 9 population studies in 8 Italian regions, for a grand total of 17,153 subjects (12,045 men and 5,108 women) aged 35-74 and for a total exposure of about 194,000 person/years were available. A chart for the estimate of cardiovascular risk (major coronary, cerebrovascular and peripheral artery disease events) in 10 years was produced for men and women aged 45-74 free from cardiovascular diseases. Risk factors employed in the estimate were sex, age (6 classes), systolic blood pressure (4 classes), serum cholesterol (5 classes), diabetes, and cigarette smoking (4 classes). Estimates were produced for absolute risk and for relative risk, the latter against levels expected in the general population that produced the risk functions. Software was produced for the separate estimate of major coronary, cerebrovascular and cardiovascular events (the latter made by coronary, cerebrovascular and peripheral artery disease of atherosclerotic origin) for follow-up at 5, 10 or 15 years, in men a women aged 35-74 years at entry and free from cardiovascular diseases. Risk factors employed here were sex, age, body mass index, mean physiological blood pressure, HDL cholesterol, non-HDL cholesterol, cigarette smoking, diabetes and heart rate. The output is based on several indicators: absolute risk, relative risk (as defined above), ideal risk (for a very favourable risk profile), biological age of risk, comparisons among the above indicators, the percent contribution of risk factors to the excess of estimated risk above the level of the ideal risk, and the description of trends in risk estimate in relation to repeated measurements. CONCLUSIONS: These tools represent progress compared to similar tools produced some years ago by the same Research Group.

Abstract: OBJECTIVE: The first objective was to study the long-term association of a casual measurement of systolic blood pressure (SBP) with cardiovascular deaths (CVD) and all causes of death (ALL) occurring during 35 years of follow-up in different population samples of men aged 40-59 years in five European countries. The second objective was to study the predictive power of early change in SBP levels (years 0-10) in relation to late fatal events (years 10-35). DESIGN, SETTING AND PARTICIPANTS: A single measurement of SBP was considered in cohorts in Finland, The Netherlands, Italy, Serbia and Greece for a total of 6507 men. Three partitioned proportional hazards models were solved, one for each independent and subsequent time block of 10 years, after excluding data from the first 5 years, to predict the risk of cardiovascular disease deaths of atherosclerotic origin (CVD) and all cause mortality (ALL). Independently, the predictive power of SBP changes (Delta-SBP) occurred during the first 10 years of follow-up was explored as a possible additional risk factor in relation to CVD and ALL deaths occurring between year 10 and year 35 of follow-up. RESULTS: Partitioned hazard scores derived from the three partitioned functions were cumulated. The resulting curves showed a continuous and significant association of baseline SBP with CVD and ALL deaths during three decades, although the strength of association declined significantly from the first to the third decade. The relative risk for 20 mmHg of SBP (and its 95% confidence intervals) in predicting CVD deaths was 1.65 (1.54-1.77) for the first 10-year block; 1.33 (1.24-1.42) for the second block; and 1.22 (1.13-1.31) for the last 10-year block. The corresponding levels of ALL deaths were 1.41 (1.34-1.49), 1.26 (1.19-1.32) and 1.11 (1.05-1.17). Changes in SBP during 10 years (Delta-SBP) added predictive power to baseline measurements in a direct and significant way, with a relative risk for a change of 10 mmHg of 1.14 (1.10-1.17) for CVD deaths and 1.11 (1.09-1.13) for ALL deaths. CONCLUSION: A single measurement of systolic blood pressure in middle-aged men maintains a strong relationship with fatal CVD and ALL deaths during the next 35 years, although for late events the strength of the association definitely declines. Changes in systolic blood pressure levels during the first 10 years of follow-up add predictive power, while baseline measurements retain their predictive power.

Abstract: BACKGROUND: Awareness and treatment of hypertension have markedly increased in the last 30 years in most parts of the world, but a satisfactory control of blood pressure is still infrequent OBJECTIVES: To describe trends in community control of hypertension and blood pressure levels in the small town of Gubbio, Italy. METHODS: Large samples of the populations (aged 30-79 years) were examined 6 years apart for measurement of blood pressure, other cardiovascular risk factors and knowledge, attitude and practice towards control of hypertension. Data were available from a total of 1125 men and 1445 women with two examinations and 1566 men and 1658 women with at least one examination. Two different definitions of hypertension were used (old definition: systolic blood pressure (SBP) > or = 160 mmHg or diastolic blood pressure (DBP) > or = 95 mmHg or use of antihypertensive drugs; recent definition: SBP > or = 140 mmHg or DBP > or =90 mmHg or use of anti-hypertensive drugs). RESULTS: Awareness, treatment and control of hypertension increased from one survey to the other, whatever definition of hypertension was used. Control rose from 41 to 63% (old definition) and from 12 to 24% (recent definition). In a 6-year period, the average population SBP declined 2-8 mmHg and DBP declined 2-3 mmHg depending on type of analysis, against an expected rise of 9 mmHg for SBP and 2 mmHg for DBP. These trends are partly explained by a marked decline in alcohol consumption and by more common and intensive anti-hypertensive treatment, while change in body mass index, which showed a slight but systematic increase, cannot be considered as a contributor to this trend. CONCLUSIONS: An epidemiological study has motivated a population group and its medical profession towards a better control of hypertension.

Abstract: BACKGROUND: Hypertension is a dominant characteristic in the prediction of cardiovascular diseases (CVDs). We aimed to evaluate the association of blood pressure measurements with CVD mortality among different populations of the world. METHODS: A total of 12 763 men, aged 40 to 59 years, from 7 countries (United States, Japan, Italy, Greece, former Yugoslavia, Finland, and the Netherlands) were surveyed from 1958 to 1964. Follow-up for vital status and causes of death was carried out over 25 years. RESULTS: All baseline blood pressure measurements were the best predictors of CVD mortality, compared with age, physical activity, total serum cholesterol level, body mass index or height, and smoking. Moreover, pulse pressure and diastolic and systolic blood pressures were the best predictors for CVD death, followed by mean and mid blood pressures. The age-adjusted hazard ratio per 10-mm Hg increase in pulse pressure varied among cohorts from 1.19 in the United States (P = .04) to 1.29 in southern Europe (P = .01). Differences among cohorts were not significant. In the pooled cohorts, pulse pressure measurements were also a significant predictor for coronary heart disease (hazard ratio per 10-mm Hg increase, 1.15; P = .04) as well as stroke death (hazard ratio per 10-mm Hg increase, 1.32; P = .01). CONCLUSIONS: Pulse pressure followed by diastolic and systolic blood pressures were the best predictors for CVD mortality among other blood pressures, as well as age, physical activity, total serum cholesterol level, anthropometric indexes, and smoking habits. No significant differences were observed among the different populations studied.
