Coronary risk factors and silent ischemic heart disease. The ECCIS Project.
An epidemiological study was conducted on 5163 men aged 40-59 years, made by occupational samples, from Florence and Rome to identify, by a three-stage procedure, subjects with asymptomatic silent ischemic heart disease (SIHD). This report describes some coronary risk factors. Men who are free from heart disease were compared with: (1) those having a low probability of SIHD (ECG signs only; n = 439); (2) those having a high probability of SIHD (ECG signs plus echographic signs, or positive markers of deficient perfusion, or altered radionuclide ventriculography; n = 104); (3) those having a definite SIHD (signs of the first two groups plus evidence from coronary angiography; n = 25). A clearcut increasing trend in the levels of major coronary risk factors, and in the multivariate estimated coronary risk for major events was found. The difference was not significant between highly probabile and definite cases of SIHD, due to the small numbers involved. Three multiple logistic models, with the three probability levels of silent ischemia as end-points, showed that four of 10 tested factors were associated with the presence of SIHD: age, systolic blood pressure, cigarette smoking and non-HDL serum cholesterol.
