Some patients, due to angina symptoms, come to the clinic after coronary angiography, through a comprehensive analysis of the placement of stents, at this time, in general, the heart does not occur ischemic necrosis, so after placing a cardiac stent, after observing for 1~2 days, the vital signs are stable, and there is no bleeding from surgical incisions can be discharged from the hospital. Some patients may be in the early stage of acute myocardial infarction, the placement of cardiac stents, myocardial blood supply is restored in a timely manner, the hospitalization period is stable, there is no cardiac insufficiency, myocardial enzymology is normal, usually about 5~7 days can be discharged. Some patients with more extensive coronary artery lesions and unstable condition after stenting need longer hospitalization, and there is no specific statistical data on the time of discharge, and malignant arrhythmia and sudden death may also occur during hospitalization.
