Cold sweating in a heart attack

In the case of myocardial infarction, the patient’s occurrence of a wet, cold sweat is most often associated with severe chest pain. The pain is usually pressing or burning and is localized to the back.

Another reason for the occurrence of cold sweats in a heart attack is the intense feeling of anxiety that arises in this situation. This is primarily a fear for your own life, a fear of death. Impaired blood supply to the heart also plays a role, reducing the amount of oxygen flowing to the heart.

Sweating during physical activity or in hot weather is healthy. But when individuals begin perspiring while experiencing discomfort in their chest, arm, neck or jaw – with little or no exertion – it could be the onset of a heart attack, according to a new study at the University of Illinois at Chicago.
