ABSTRACT:
Key Words: Acute myocardial Infarction season, cold, mortality
We studied 395 consecutive patients with acute myocardial infarction ,admitted to Poor -sina Hospital Rasht , Iran ,over two years(during the period 1-1-61 to 29-12-62), and correlated the incidence of the disease inhospital mortality and 10-year posthospital mortality and with seasons.
There was no seasonal variation in the incidence of acute myocardial infarction.
The frequency of inhospital mortality was significantly higher in cold seasons(Autumn and winter).compared with other seasons (spring and summer )(63 percent vs.37 percent , Pless than 0.05).
Inhospital mortality of patients from acute myocardial infarction that were admitted to hospital in cold seasons was higher than that in other seasons (24.2 percent vs.15.6 percent , Pless than 0.05).
The seasons had no influence on incidence of 10-year posthospital mortality of survivors of acute myocardial infarction but ,overall mortality (inhospital and posthospital ) was significantly higher in cold Seasons than that in other seasons ( 58.1 percent vs.41.9 percent ,Pless than 0.025 ).
This study indicates that inhospital and 10- year overall mortality of acute myocardial infarction is higher in cold seasons.
