Coronary atherosclerotic heart disease, or coronary heart disease for short, is a major killer of human health. If the coronary arteries become diseased, the part of the heart muscle responsible for the coronary arteries will not be able to receive oxygen and nutrient supply, so this part of the heart muscle begins to gradually die, resulting in myocardial infarction! Why do coronary arteries become diseased? There are three causes of coronary artery lesions: 1, coronary artery occlusion Atherosclerosis is one of the important reasons for the reduction of blood flow, by fat and other substances composed of plaque will lead to coronary artery stenosis, plaque once rupture, will form a thrombus, so that through the coronary artery of the blood flow is seriously reduced or completely interrupted, so the thrombus is the direct cause of the occlusion of the coronary arteries. 2, the coronary artery spasm situation Drugs, smoking, cold weather, great pressure or emotional fluctuations will induce coronary artery spasm, so that the supply of blood flow to the heart muscle is suddenly interrupted, and then induced angina pectoris. The main performance in shortness of breath, dizziness, nausea, cold sweat. 3.Coronary artery entrapment Coronary artery entrapment is due to the separation of the arterial lining leading to the obstruction of blood flow. After aortic dissection, the branch vessels on the aorta form a false lumen and squeeze the normal blood vessels, interrupting the blood flow and thus affecting the blood supply to the heart muscle. What is the best way to improve coronary artery disease? Patients can take aspirin or other lipid-lowering medications to prevent blood clots from forming; thrombolytic drugs to dissolve clots that have formed; nitroglycerin, morphine, etc. to reduce coronary artery spasm and relieve pain; and beta-blockers to slow down the heart rate and reduce oxygen consumption. Coronary intervention involves delivering a balloon catheter to the occluded area of a blood vessel, expanding the balloon, and withdrawing the balloon after the vessel opens, leaving the stent in the vessel to keep it open. Coronary artery bypass surgery A surgical procedure in which a venous blood vessel or an artificial blood vessel is attached to the narrowed ends of the coronary arteries to form a new channel, allowing blood to flow freely around the narrowed area. If the coronary arteries are diseased, the body will experience sudden chest pain, tightness in the chest, burning sensation in the chest, pain radiating to the upper abdomen, shoulders, upper arms, neck and jaw, and other discomforts, including shortness of breath, dizziness, nausea, and cold sweat. Experts remind that these signs of coronary artery disease should not be ignored, and should be promptly sought medical attention.
