Myocardial microinfarction

Myocardial microinfarctions are small injuries to the heart muscle that can occur for a variety of reasons. These damages can impair heart function and cause symptoms such as chest pain, shortness of breath, weakness, and others.

Microinfarctions can be caused by a variety of factors, including stress, smoking, high blood pressure, diabetes, and other diseases. If a microinfarction occurs, it is not always accompanied by chest pain and shortness of breath.

According to research, microinfarctions are one of the key causes of chronic heart failure. They can contribute to the development of complications such as aritis

Myocardial microinfarctions are a consequence of myocardial ischemia, due to the presence of local disturbances of blood flow in the myocardium. In general, myocardial ischemia is a failure of normal, sustained cardiac activity that occurs when there is insufficient blood supply caused by decreased blood flow in the cardiac arteries during the existence of coronary heart disease. Often, microinfarctions occur at the site of small foci in diabetic cardiopathy, in the form of two-point red-blue spots during dissection of the aorta or fibrinous plaques during dissecting aortic aneurysm. Unfavorable signs of microinfarctions that require urgent intervention are weakness, vomiting, dizziness, and muscle weakness.
