The most common sequelae of cardiac interventions are arrhythmias, abnormal coagulation, hyperlipidemia and hypertension, coronary artery disease, and localized bruising and petechiae of the skin. Interventional cardiac surgery is an emerging means of combining diagnosis and treatment for patients with coronary artery disease, angina pectoris, and myocardial infarction can be used both to diagnose the disease and as the main method of treating the disease, and the residual sequelae are relatively rare. The advantages of interventional cardiac surgery outweigh the disadvantages, and for most heart diseases, interventional cardiac surgery can be used to treat the disease and greatly reduce the pain of heart disease patients. It is less traumatic, safer and more effective for patients of all ages and plays a leading role in cardiovascular medicine and surgery, with fewer adverse effects and fewer sequelae.
