Risk of Cardiovascular Morbidity and Mortality in Relation to Temperature

Extreme temperatures are consistently shown to have an effect on CVD-related mortality. The association between weather and CVD-related morbidity is less clear. We analyzed daily weather, ED visits classified as CVD-related based on chief complaint text, hospitalizations, and natural cause deaths that occurred in New York City. We observed lower risk of CVD-related ED visits and hospitalizations during cold and hot temperatures. The effects of extreme temperatures on CVD-related morbidity may be explained by behavioral patterns, as people are more likely to stay indoors on the coldest and hottest days
