What are the causes of extensive myocardial necrosis?

summary

Myocardial necrosis should be medical myocardial infarction, which refers to the rapid reduction or interruption of coronary artery blood supply, resulting in local necrosis of the corresponding part of the myocardium due to severe persistent ischemia. Myocardial infarction refers to the death of myocardial cells caused by prolonged ischemia, which is the result of the imbalance between supply and demand of myocardial perfusion. Myocardial ischemia can often be found through the patient's medical history, ECG and myocardial enzyme changes. Pain was the earliest and most prominent symptom, with severe degree. The blood supply of the tubular artery is sharply reduced or interrupted, which makes the corresponding part of the myocardium suffer from severe persistent ischemia. Let's share my experience with you.

What are the causes of extensive myocardial necrosis?

Coronary artery atherosclerosis unstable plaque rupture and erosion, and then bleeding and intraluminal thrombosis, resulting in partial or complete acute occlusion of coronary artery, and collateral circulation is not fully established, the corresponding coronary blood supply site myocardial serious and persistent acute ischemia for more than 20 minutes, myocardial infarction can occur.

Lack of blood supply to the heart leads to myocardial hypoxia. The main manifestations were palpitation, discomfort in the heart area, sometimes pain in the heart area or angina pectoris; Shortness of breath, exercise, satiety or excitement are more serious, and the whole body is weak; In severe cases, shock may occur for a short time. Myocardial edema is one of the main clinical symptoms of dilated cardiomyopathy.

It is a kind of myocardial damage, which may be related to the immune myocardial damage after virus infection. It is generally seen in the ultrasonic examination of dilated cardiomyopathy. It can be used as a differential diagnosis with other cardiomyopathy. This is a slow but effective compensatory function, which mainly occurs in the case of long-term pressure overload.

matters needing attention

Health publicity and education for patients and their families, so that patients and their families have a knowledge of the disease, understand the significance of various prevention and control measures, so as to reduce their worries about the disease, and actively cooperate in the prevention and treatment. Arrange a reasonable diet to reduce the intake of total fat, saturated fatty acids and cholesterol.
