Coronary atherosclerotic heart disease, or coronary heart disease, is a major killer of human health. If the coronary arteries are diseased, the part of the heart muscle that is responsible for the coronary arteries does not receive oxygen and nutrients, and this part of the heart muscle begins to gradually die, leading to myocardial infarction! How can we improve the coronary artery lesions? 1.Medication Patients can take aspirin or other lipid-lowering drugs to prevent thrombus formation; use thrombolytic drugs to dissolve the formed thrombus; use nitroglycerin, morphine, etc. to reduce coronary spasm and relieve pain; use beta-blockers to slow down the heart rate and reduce oxygen consumption. 2.Coronary intervention is to send the balloon catheter to the occluded part of the blood vessel, expand the balloon, and after the blood vessel is opened, the balloon is withdrawn and the stent is left in the blood vessel to maintain the blood vessel open. 3.Coronary artery bypass surgery is a surgical procedure to build a new channel by placing a vein or an artificial blood vessel at both ends of the narrowed coronary artery, so that the blood can flow smoothly again around the narrowed area. In case of coronary artery disease, the body may 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, as well as shortness of breath, dizziness, nausea and cold sweat. Experts remind that these signs that indicate coronary artery disease should not be ignored and should be promptly sought.
