SUMMARY
This is a study of 306 patients with 330
episodes of myocardiai infarction admitted to
Reykjavik City Hospital during 1972-1975. The
overall ratio of maies to females was 3.3:1 or
253 males and 77 females. The mean age for
the males was 61.8 years and for the females
66.9 years.
The mortality rate was 21.8% which repre-
sents a decrease of 8.1% compared to a retro-
spective study done at the same hospital dur-
ing 1956-1968. This decrease in mortality is
ascribed to the coronary care unit which was
established in 1971. The mortality was similar
in anterior and inferior infarctions but was
greater if the infarction extended to the later-
al part of the heart.
58.5 patients had arrhythmias of which
ventricular estrasystoles were most common.
20% of the patients are admitted through
the emergency room.
Compared to the former study, the median
time from the onset of symptoms to admission
decreased from 13 hours to 4 hours and 20
minutes. Thirty patients were successfully re-
suscitated. Of those 14 patients were dis-
charged alive.
