In the years 1985, 1986 and 1987, the MONICA Augsburg Coronary Event Register recorded 1488 coronary events (1214 men and 274 women) occurring in 35-64 year old residents of the study region (population: 102,000 men and 105,000 women). The rates presented include all coronary events with a definite acute myocardial infarct (AMI), possible AMI, resuscitated cardiac arrest, and insufficient data. The age-standardized attack rates in men are 390 (1985) to 372 (1987) and in women 51 (1985) to 72 (1987) per 100,000 population. The age-standardized 28-day case fatalities in men are 44 (1985) to 44 (1987) and in women 67 (1985) to 55 (1987) per 100 coronary events. With the exception of the attack rates in women, no statistically significant differences between yearly rates could be established.
