A group of 514 males between the ages of 35 and 44, whose occupation involved strained mental work, were examined. Ischemic heart disease was diagnosed in 56 of them (10.7%); 191 formed a group with doubtful signs of ischemic heart disease, and 267 composed a group of practically healthy persons. Hypertensive disease was revealed in 18.4% and hyperlipoproteinemia in 20% of persons examined. There was a statistically significant difference between the group of healthy individuals and that of patients with ischemic heart disease in the frequency of hypertensive disease and hyperlipoproteinemia. Smoking, adiposity, low physical activity, and aggravated heredity were encountered at a practically equal rate in both groups. In half of the patients with ischemic heart disease hypertensive disease and hyperlipoproteinemia were not found, while other risk factors of ischemic heart disease were encountered no more frequently than in the group of healthy persons. Thus, just like most other epidemiologic studies, our investigation showed hypertensive disease and hyperlipoproteinemia to be of highest significance as ischemic heart disease risk factor. |
