Epidemiological study of myocardial infarction and cerebral apoplexy in survival and deceased subjects.

The risk factors for myocardial infarction and cerebral apoplexy were retrospectively studies on residents in a city with the population of 100,000. The average age of the deceased subjects was relatively high in myocardial infarction compared with other diseases studied in this report. Hypercholesterolemia was also found in case of the deceased myocardial infarction. The most important risk factor for cerebral hemorrhage and subarachnoid hemorrhage was hypertension. Serum cholesterol in the deceased subjects with cerebral hemorrhage and cerebral thrombosis was elevated 10% during the last decade of the study whereas in myocardial infarction it remained unchanged.
