More Heart Attacks Occur in Cooler Weather

As temperatures cool, the number of heart attacks rise, claim researchers from the London School of Hygiene and Tropical Medicine (LSHTM). "Older people between the ages of 75 and 84 and those with previous coronary heart disease seemed to be more vulnerable to the effects of temperature reductions," says lead researcher Krishnan Bhaskaran. He adds that those who take aspirin long term were less vulnerable to heart attacks in cooler weather. The study results, published in the British Medical Journal, also suggest that even in summer, heart attack risk is increased by temperature reductions. Researchers concluded that short term increase in heart attack risk is linked with lower ambient temperature, mainly in the two weeks after exposure.
