title: Sudden cardiac death in Japanese people aged 20-60 years--an autopsy study of 133 cases.
abstract: In order to elucidate the principal cause and actual circumstances of sudden cardiac death in Japan, especially among people in the prime of life, we investigated 133 out of 161 autopsied patients (82.6%) (106 men and 27 women, mean age 47.5 years). Coronary artery disease (CAD) was the most frequently detected disorder (50 cases, 37.6%), and included 15 cases of acute myocardial infarction (AMI) (11.3%). We found that CAD was less frequent among younger patients than in Western countries: 10.0% in subjects in their twenties and 22.2% among subjects in their thirties. The left anterior descending artery (LAD) was the vessel most often affected by infarction (47.0%), but the proportion of LAD lesions was not different from that in AMI patients who were survived for least 1 day after the attack. In conclusion, CAD was infrequent among patients aged 20-39 years in comparison with Western countries and LAD was the most commonly affected vessel, but the proportion was not different from that found among AMI patients who survived for at least 1 day after the attack.
