Long Exposure to Heatwaves Can Lead to the Risk of a Deadly Heart Attack. Here’s How!

Managing Heart Failure, Diabetes, and Kidney Disease: A Comprehensive Approach

High temperatures during heatwaves can cause excessive perspiration, which can result in dehydration. Dehydration lowers blood volume, which can elevate blood pressure and put more strain on the heart. This increased cardiac strain, especially in those with pre-existing cardiac problems, can cause a heart attack.

Heat waves have the potential to worsen pre-existing cardiovascular diseases, including hypertension, congestive heart failure, and coronary artery disease. High temperatures have the potential to escalate the heart’s oxygen demand, perhaps straining already-weakened cardiovascular systems and resulting in a heart attack.

Extended exposure to high temperatures may result in an imbalance of electrolytes, particularly potassium and sodium, within the body. The heart and other organs need these electrolytes to continue functioning properly. An imbalance in electrolytes can disrupt the heart’s rhythm (arrhythmia) and increase the risk of a heart attack.

The body can experience heat stress from prolonged exposure to high temperatures. In order to remove heat and maintain a steady internal temperature, heat stress causes the body to activate its natural cooling processes, which include sweating and the dilatation of blood vessels close to the skin. Heart rate and cardiac output rise as a result of this reaction, which also makes the heart work harder to push blood to the skin’s surface for cooling. This increased cardiac strain can raise the risk of cardiovascular events, such as heart attacks, in people with underlying cardiac problems.

Poor air quality is frequently linked to heatwaves, particularly in urban areas where pollutants from industrial and vehicular emissions build up. Heatwave-related exposure to air pollution can aggravate oxidative stress and inflammation in the body, which can help in the onset and advancement of cardiovascular illnesses. Particularly in sensitive groups of people, inflammation and oxidative stress can harm blood vessels, raise the risk of blood clots, and compromise heart function, increasing the risk of heart attacks.

To conclude with, these heatwaves can lead to heart attack in number of ways. So, you should take extra care during heatwaves, especially if you have underlying cardiac issues. Precautions include drinking enough water, avoiding extended exposure to high temperatures and seeking medical attention if experiencing symptoms of heat-related illness or cardiovascular distress.
