Studies suggest that hot weather extremes may increase the risk of heart attacks or death related to heart attacks.

Very hot weather is dangerous for those with heart disease, the elderly, and persons taking many cardiovascular medications that limit a person’s ability to cope with heat.

Diurnal temperature or temperature change on successive days also increased myocardial infarction risk.

Higher ambient temperatures above a threshold of 68°F (20 °C) seem to be associated with a transiently increased risk of myocardial infarction 1-6 hours after exposure. Reductions in risk at longer lags are consistent with heat triggering myocardial infarctions early in highly vulnerable people who would otherwise have had a myocardial infarction some time later (“short term displacement”). Policies aimed at reducing the health effects of hot weather should include consideration of effects operating at sub-daily timescales.

The risk of acute myocardial infarction death in women was greater than in men during the heat wave period.

The risk of acute myocardial infarction death among those older than 64 age group was greater than the under 65 year olds.

The impact of heat wave to the elderly female was greater. See more news…
