[Myocardial infarction and meteorology]

The authors have investigated retrospectively over two years (1977-1978) a possible relationship between daily admissions for myocardial infarction at the University Cantonal Hospital, Geneva, and the weather. Statistical analysis of 963 emergency patients (572 with patent myocardial infarction and 391 with possible infarction at the admission center) shows that this correlation exists. One weather feature, the warm front, has been identified during which there is a significant increase in the number of coronary cases admitted. This weather situation appears to be a contributory factor in triggering a coronary accident.
