summary

Myocardial strain refers to the long-term excessive work of the myocardium under high load. For example, excessive obesity, high blood pressure, work stress, mental pressure and other factors can lead to myocardial damage. At this time, the new machine may also be ischemic, or the blood supply may be normal. If myocardial ischemia is confirmed, the long-term development may lead to coronary heart disease, myocardial infarction and dilated heart disease Myopathy, cardiac insufficiency, heart failure and so on. How is myocardial strain caused? Let me talk about it.

How is myocardial strain caused

First, the most common reason is because of various virus infections. So far, more than 30 kinds of viruses have been found to cause myocarditis, among which Coxsackie virus, Aike virus, coronavirus, etc. are the most common, followed by other viruses, such as influenza virus, mumps virus, varicella virus and herpes virus.

Second: in recent years, it has been found that hepatitis B virus can also lead to myocarditis. Myocarditis can occur in all kinds of bacterial infections, such as severe sepsis caused by Staphylococcus aureus, Escherichia coli and other bacteria, shock and long sores and suppurations commonly seen in surgery, etc. after these bacterial infections reach the human body, they grow and reproduce in the blood, and then release various toxins, Toxins are highly toxic and can damage the brain.

Third: the general elderly engaged in occupation need high mental tension, less exercise crowd, obesity and hyperlipidemia in patients with T wave changes, should be suspected of myocardial ischemia lesions, especially in patients with angina pectoris attack in the past, should be more vigilant.

matters needing attention

In daily life, first of all to change the way of life, to appropriate physical exercise, diet control, blood lipid control, when necessary, a hospital examination, myocardial strain, itself does not have any symptoms, if it is caused by coronary heart disease or angina pectoris, appropriate application of nitroglycerin and other vasodilator drugs.
