Coronary calcification is generally more difficult to recover from. Coronary artery calcification is caused by the deposition of calcium salts on the coronary arteries, which often indicates the possibility of coronary stenosis. For patients with chest tightness, chest pain, hypertension, hyperlipidemia and hyperglycemia, it is recommended to perform electrocardiogram, ambulatory electrocardiogram, cardiac enzymes, cardiac ultrasound and, if necessary, coronary artery imaging to clarify the presence of coronary artery stenosis, the degree and location of stenosis and to give If necessary, coronary intervention or surgical coronary artery bypass grafting will be performed. The stenosis of coronary arteries can be removed by surgery, but in the case of coronary calcification, it is often irreversible and requires comprehensive treatment.
