BACKGROUND: Coronary artery disease (CAD) represents the most common cause of morbidity and mortality in the Czech Republic. The aim of this study is to analyze long-term cardiovascular diseases (CVD) mortality, identify predictors of outcome and to validate the Framingham risk function in men from the Czech Republic. DESIGN AND METHODS: A 20-year primary prevention study of atherosclerosis risk factors in 1417 men from Prague aged 38-53 years was launched in 1975 (STULONG). RESULTS: When analyzing CVD mortality, heavy smokers had hazard higher than non-smokers and light smokers (p < 0.0001); hypertensives higher than normotensives (p < 0.0001); men with hypercholesterolemia higher than those with normal cholesterol (p = 0.0432), and university-educated men lower than elementary-educated men (p = 0.0006). In 1980-1984, the age specific mortality from CVD in men from STULONG was higher (p = 0.0132) than in the Czech Republic, in 1985-1994 insignificantly lower. The Framingham risk function underestimated the absolute 10-year risk of CAD across the quintile of the risk (p < 0.0001), with 63% discrimination. CONCLUSION: In STULONG, the mortality from CVD was significantly associated with known risk factors (hypertension, smoking, hypercholesterolemia, education); the Framingham risk function underestimated the absolute 10-year risk of CAD.
