Myocardial fibrosis, also known as myocardial calcification, is a chronic ischemic heart disease resulting from persistent myocardial fibers caused by moderate to severe atherosclerotic stenosis of the coronary arteries and/or recurrently exacerbated myocardial ischemia and hypoxia, leading to the gradual development of heart failure. When the myocardium is chronically or acutely ischemic and hypoxic for a long period of time, it will lead to necrosis of cardiomyocytes, and after the necrosis of cardiomyocytes, they will generally be replaced by fibrous tissues, and myocardial fibrosis will occur. Cardiomyocytes are non-renewable cells, and the loss of one is one less, so myocardial fibrosis cannot be reversed. Patients may experience arrhythmias, heart failure and other symptoms, and need to follow the doctor’s instructions for standardized treatment. Patients with myocardial fibrosis should consult a doctor in time and actively cooperate with the doctor for treatment.
