175
patients who died suddenly and underwent autopsy.
Among men 20-39 years the age corrected incidence was
0.16 cases per 1,000 men per year during the years
1980-1984. Between January lst 1980 and December
3lst 1984 43 individuals aged 40 years and younger
suffered acute myocardial infarction in Iceland. Three
were foreigners and among the Icelandic patients two
were 17 years old, one had hypertrophic
cardiomyopathy and the other suffered chest trauma
but neither of those had any signs of coronary
atherosclerosis on coronary angiography. During the
study period 38 Icelanders in the age group 25-40 years
suffered myocardial infarction. Of those 9 (23.7%) died
before they reached hospital and 2 patients (6.9%) died
during the hospital stay. This accounts for 6.1% of the
total mortality in the age group 25-39 years during the
years 1980-1983. Risk factors were examined among the
29 patients who were admitted to hospital. Only one
patient was defined as a non smoker and 28 patients
(96.6%) smoked daily. Of the 29 hospitalized patients
there were 15 who had a first degree relative with known
coronary heart disease. Hypercholesterolemia,
hypertension and obesity were not found to be
significant risk factors. One vessel disease was most
common (59.4%) and most frequently involved the left
anterior descending artery.
