The Bucharest multifactorial prevention trial. The changes of morbidity and of general and specific mortality

Abstract

The paper presents the results of the Bucharest multifactorial prevention trial of coronary heart disease, concerning changes in cardiovascular morbidity and mortality during the first 5-year-period of follow-up. The age adjusted 5-year-rates disclose important reductions in the intervention group in comparison with the control one: for hard events (myocardial infarction, stroke, acute coronary insufficiency)--by 41%; for myocardial infarction--by 35%; for coronary mortality--by 38%; for stroke--by 39%; for cardiovascular mortality--by 30%. The decrease of hard events, myocardial infarction and stroke incidences are statistical significant. The evolution curves of cardiovascular morbidity and mortality show that both groups (the intervention as well as the control one) began with near the same values, but on the way and especially after 5 years they are differently located, those of the control group being higher than those of the intervention group.
