Cardiac stenting is a new technique that has been developed in the last 20 years or so to improve the insufficient blood supply to the heart muscle and blockage of the heart arteries caused by coronary artery disease. Simply put, the process of cardiac stent surgery treatment is to puncture the peripheral blood vessels, such as the radial artery, femoral artery, so that the catheter travels forward in the blood vessels to reach the opening of the coronary artery, using a special delivery system to deliver the stent to the lesion site where it needs to be placed, releasing the stent, withdrawing the catheter, and concluding the procedure, so as to restore the normal blood supply to the original severely narrowed arteries. This is extremely important for improving the quality of life of heart patients. Stent surgery is a small operation, but requires a high level of technology, after the operation is not once and for all, there are still some issues that need attention: First, regular review work should be done, 1 month after discharge, 3 months and half a year time to review, if there are special circumstances at any time to follow-up, mainly because patients with coronary heart disease to oral statin, the need to detect myocardial enzymes, liver and kidney function and lipid profile, in addition to oral antiplatelet agents Need to test the blood routine. Every six months need to improve the heart ultrasound examination. Second, on time medication: coronary heart disease patients life-long medication, not because of the stent, stent surgery may be more than one or two kinds of drugs, time will also gradually stop part of the drug, according to the condition and time. But the drugs to prevent stenosis in the stent must be eaten well, to prevent further narrowing. C. Adopt good living habits, quit smoking and drinking, test blood pressure and heart rate every day, keep a good record and show it to the doctor when you follow up. Quit smoking and alcohol, low-salt, low-sugar, low-fat diet, ensure adequate sleep, avoid sedentary, moderate exercise, weight loss or weight control, maintain a comfortable mood, etc.. If it is because of angina pectoris without myocardial necrosis, then most of the patients can move around freely, playing ball games, swimming and running are all fine.
