A new research report has been published in Taiwan that says people that have had heat strokes in the past have a 2.5 times higher risk of myocardial infarction than people that have never had a heat stroke. This is the first time in the world, that a high correlation has been found between heat strokes and myocardial infarction.
Researchers at Tri-General Service Hospital have found a link between heat stroke and myocardial infarction. The team compared the national health insurance records of 882 heat stroke patients and followed up with them over a period of 12 years. Of the 628 that had a heat stroke but no history of heart disease, 30 percent later developed ischemic heart disease.
The ischemic heart disease rate for patients that have had heat stroke is around 30 percent. For patients that haven't had heat stroke, it's around 14 percent.
The team believes heat stroke leads to inflammation in the body, damaging endothelial cells and causing atherosclerosis. This in turn raises the risk of ischemic heart disease. People that have had heat strokes should therefore get cardiac exams to lower the risk of heart disease.
Without early diagnosis, sudden acute myocardial infarction, heart failure or arrhythmia are possibilities. The fatality rate is very high.
Doctors say heart attacks are most common in the three to five days after temperatures suddenly drop over 10 degrees and anyone experiencing symptoms including tightness in the chest, cold sweats, and nausea that don't go away after resting for five minutes should seek immediate medical attention.
