Seasonal incidence of myocardial infarction

ABSTRACT

100 cases of coronary thrombosis seen in a consulting practice in Port-of-Spain have been analysed with regards to the monthly incidence of the disease. The figures show a significantly higher number in January and July and a significantly lower number in December. There is no apparent relation between the incidence of the disease and average monthly temperature or humidity. A psychological explanation is put forward for the highest incidence in January and the lowest in December. (AU)
