A clinico-epidemiological study of the patients who developed stroke or myocardial infarction from April 1989 to March 1991 was done in Saku District, Nagano Prefacture. Four hundred fifty cases of stroke were registered during the two years. Annual incidence rate of stroke stood at 205.2 per 100, 000 population . The distribution of stroke types was 66.2% in cerebral infarction, 24.0% in cerebral hemorrhage and 9 .8% in subarachnoid hemorrhage and male/female ratio was 1.2. Two hundred fifty seven cases of stroke in the first year were followed up during one year after the onset. Case-fatality rate within 28 days after onset of stroke was 15.5%. After one year 132 cases (51.4%) did not need help for activities of daily living and 53 cases (20.6%) need it. Seventy cases (27.2%) were fatal. Two cases (0.8%) were unknown. Eighty cases of myocardial infarction were registered during the two years. Annual incidence rate of myocardial infarction stood at 36 . 5 per 10 0.000 population and male/female ratio was 2.5. Thirty eight cases of myocardial infarction in the first year were followed up during one year after onset. The case-fatality rate within 28 days after onset of myocardial infarction was 10.5%. Seven cases (18.4%) were fatal within one year. The incidence rate of stroke was 5.6 times higher than that of myocardial infarction.
