The incidence of cardiovascular spasm improves after smoking cessation and the incidence of spasm theoretically decreases. If cardiovascular spasm still occurs after cessation of smoking, it is necessary to pay attention to lifestyle and intensify medications to prevent coronary vasospasm. Cardiovascular spasm is an important cause of myocardial ischemia, which occurs when coronary vasospasm occurs and blood flow is interrupted, causing myocardial ischemia. Smoking and drinking alcohol, cold air stimulation, are easy to stimulate blood vessels spasm. The occurrence of vasospasm can be avoided by quitting smoking. If vasospasm still occurs after quitting smoking, it is recommended that patients avoid emotional excitement, reduce cold air stimulation and other aspects of control. Treatments such as oral aspirin for thrombosis prevention and oral statins for endothelial stabilization should be maintained. Oral calcium antagonists such as diltiazem prevent vasospasm. Severe vasospasm may lead to the occurrence of myocardial infarction, and it is important to visit the cardiology department for formal treatment.
