Heart and Stroke Foundation warns of heat risk for people with cardiovascular conditions

The Heart and Stroke Foundation is warning that the current heat wave in Central Canada may be especially dangerous for people with cardiovascular conditions, including those taking certain heart and blood pressure medications. The organization says extreme heat increases strain on the heart because the body has to move more blood to the skin to help cool itself. It also says dehydration can raise the risk of heatrelated illness, and recommends drinking water regularly, avoiding the hottest part of the day, and using cooling spaces such as libraries or malls when needed. The foundation says people should watch for signs of dehydration and be alert for heat stroke, which it describes as a medical emergency. Symptoms can include confusion, fainting, a rapid heart rate, vomiting, headache, and skin that is hot and dry. Anyone suspected of having heat stroke should be moved to a cool place and emergency help should be called.
