CHD in Sweden: Mortality, Incidence and Risk Factors over 20 Years in Gothenburg

Abstract

Mortality from coronary heart disease (CHD) increased among Swedish men between 1968 and 1981, but after that, began to decline. CHD mortality in women decreased slightly, mostly among older women. From 1980, the incidence of non-fatal myocardial infarction (MI) started to decrease among men. Among middle-aged women, however, there was a significantly increased incidence. Mortality during the two years following hospital discharge decreased both in men and women between 1968 and 1985 in Gothenburg. Between one-sixth and one-fifth of major CHD events occur among patients with previous MI or angina pectoris. Serum cholesterol and smoking habits increased among middle-aged men from 1963 to 1973, but decreased thereafter. Blood pressure decreased, and the percentage of people on treatment increased. Blood pressure and serum cholesterol decreased among middle-aged women, but smoking and triglycerides increased. These different trends might explain an increasing CHD incidence among younger women but decreasing incidence and mortality among older women.
