Causes of myocardial strain

Myocardial strain may be caused by hyperthyroidism, viral myocarditis, coronary atherosclerotic heart disease and other reasons.

1. Hyperthyroidism

patients suffering from hyperthyroidism, can cause increased thyroid hormone secretion, leading to increased systemic circulating blood volume, so that the heart overload, causing myocardial strain.

2. Viral myocarditis

virus infection can cause viral myocarditis, the virus directly destroys the patient's myocardial cells, can cause myocardial cell necrosis, at this time will also appear myocardial strain performance.

3. Coronary atherosclerotic heart disease

Coronary atherosclerotic heart disease may cause myocardial ischemia, hypoxia, resulting in myocardial cell damage, prone to myocardial strain.
