Chronic myocardial ischemia is associated with stenosis in the coronary arteries and branch vessels of the heart, causing atherosclerotic changes.
Long-term chronic myocardial ischemia, resulting in increasing stenosis, blood supply abnormalities, triggering myocardial injury, when the coronary artery stenosis are a certain degree of blockage and can not be relieved, it will cause myocardial necrosis, that is, myocardial infarction.
Therefore, when chronic myocardial ischemia occurs, it is necessary to consult a doctor in time, under the guidance of the doctor to improve the electrocardiogram, myocardial enzymes, coronary angiography and other related laboratory tests and inspections to assess the situation of myocardial ischemia, and if necessary, rational drug therapy, coronary intervention and cardiac bypass grafting treatment, to prevent and control the further progression of chronic myocardial ischemia triggered by myocardial necrosis.
