Some Weather Conditions Associated With Heart Attack Risk

Bottom Line: Some weather conditions are associated with risk of heart attack. This observational study examined data for more than 274,000 patients who had heart attacks reported in Sweden from 1998 to 2013 and for which weather data were available over the same period of time. Days with low air temperature, low atmospheric air pressure, high wind velocity and shorter periods of sunshine were associated with risk of heart attack. The strongest association appeared to be for air temperature, with a higher risk of heart attack on days when air temperatures were less than 32°F. Although results observed in the study were statistically significant, the differences were modest.
