Coronary heart disease in the end put stent

Coronary

heart disease is caused by coronary artery atherosclerosis leading to stenosis or occlusion of the lumen, forming myocardial ischemia, hypoxia. For patients, if the degree of coronary atherosclerosis is relatively light, does not cause significant myocardial ischemia, angina pectoris, generally can be controlled by following the doctor's advice to use nitroglycerin, warfarin sodium, nifedipine and other drugs. However, if the degree of coronary atherosclerosis in patients is more serious and the degree of local stenosis is>70%, it will cause obvious myocardial ischemia, and stent placement is generally considered to dilate coronary arteries and improve myocardial ischemia.
