Inadequate blood supply to the coronary arteries is the main cause of coronary heart disease, and the causative factors are age, postmenopausal women and smokers, hypertension, hyperlipidemia, and hyperglycemia. Common risk factors for coronary heart disease include age, which may increase the risk of coronary artery damage. Postmenopausal women and smokers are more likely to develop coronary heart disease. High blood pressure leads to hardening of the arteries and thickening of the blood vessel walls, increasing the incidence of coronary heart disease. High levels of lipoproteins in the blood also increase the risk of atherosclerosis, of which LDL is often a measure. Diabetes is also associated with an increased risk of coronary heart disease. The pathomechanism of coronary heart disease is due to the formation of plaque buildup on the walls of the coronary arteries. Plaque buildup narrows the coronary arteries continuously, which may lead to partial or complete blockage of the coronary arteries, resulting in atherosclerosis. Eventually, there is insufficient supply of blood to the coronary arteries, and the heart muscle is unable to receive enough blood. Necrosis of the heart muscle may cause pain called angina pectoris, which is a common symptom of coronary heart disease. If you are already suffering from coronary heart disease, you need to go to the hospital regularly for follow-up and treatment according to the doctor’s instructions to avoid delays.
