The relation of variables obtained from a baseline examination to death from ischemic heart disease (IHD), cerebro-vascular disease (CVD) and sudden death (SUD) was analyzed in a case-control study. From questionnaire survey of approximately 180,000 subjects who underwent baseline health examinations in 1971-1986 at Aichi prefectural center of health care, 148 deaths were selected for this study. The number of cases on IHD, CVD and SUD was 36, 60, and 52, respectively. Mean age of cases was 54.8 years old and the mean follow up interval between baseline examination and death was 3.7 years. Four controls matched according to year of baseline examination, age and sex were chosen arbitrarily for each case, and odds ratios for the three diseases were estimated. In some of the matched sets, odds ratios at a follow up examination were compared with that at the first examination. The results were as follows: 1) Variables showing positive relationships to death from each of the three diseases were hypertension, high fasting blood sugar, abnormality of cardio-thoracic ratio, ST-T abnormality in ECG, left ventricular hypertrophy in ECG. The odds ratio for ST-T abnormality in ECG was significant for all three causes of death. 2) High total cholesterol showed a significant positive relation only to death from IHD. As to death from CVD and SUD, albuminuria and sclerotic changes in fundus oculi were positively and significantly related. Risk factors differed for deaths from the three diseases. 3) In death from IHD and CVD, odds ratio at the second examination was apt to be higher than that at baseline examination. In death from SUD, however, odds ratios at the first and the second examination showed no significant difference.
