Is there a link between cold weather and the risk of heart attacks?

<p style=";text-align:left;direction:ltr">ArabiaWeather - According to a large-scale study of nearly 300,000 people, low temperatures, strong winds, and the short days that come with the winter weather can increase the risk of a heart attack.</p><p style=";text-align:left;direction:ltr"> By combining data collected from the Swedish Institute of Meteorology and Hydrology with the national registry of all patients admitted to any coronary care unit in Sweden due to a heart attack between 1998 and 2013, the researchers found that the number of myocardial infarction (MI) cases increased in days.
