The danger period is usually over 24 hours after cardiac stent surgery, and complications such as cardiac insufficiency, hypotension and shock should be closely monitored within 24 hours after surgery. Cardiac stent surgery is mainly applied to patients with asymptomatic myocardial ischemia, mild angina or acute heart attack, and they can usually be discharged from bed after 24 hours of surgery, and most patients can be discharged in a stable state 3 days after surgery. It is recommended to avoid exertion and strenuous exercise for 6 months after the operation, pay attention to regular work and rest, maintain a happy and relaxed mood, avoid insomnia, constipation or bad mood; take cardiovascular disease related drugs according to the doctor’s prescription on time and in the right amount to prevent the formation of thrombus in the stent and the progress of atherosclerosis.
