Age-standardized annual attack rates of MI per 100,000 population (age 35–64) were 510.4 for males and 99.3 for females. Age-standardized annual incidence rates (first ever MI) per 100,000 population (age 35–64) were 387.4 for males and 89.7 for females. 28-day case fatality was 33.3 % in males and 31.5 % in females. Of all deaths occurring within 28 days, 75.8 % in males and 69.2 % in females occurred during the first 24 hours.
