Due to lifestyle changes and other reasons, the incidence of cardiovascular diseases, including coronary heart disease, has been increasing year by year in China since the 1980s, which requires attention, early prevention, and the establishment of good habits and a healthy lifestyle. However, if you already have coronary heart disease, you should actively treat it in order to control the symptoms and to minimize the adverse consequences such as heart attack and heart failure. The treatment of coronary heart disease includes medication, interventional therapy and surgery, and the treatment should be chosen scientifically according to the condition. Generally speaking, people with mild coronary stenosis can use medication to control symptoms; if medication is not effective, they should receive stent surgery or bypass surgery in time, which can eliminate angina and enable patients to live and work normally, and more importantly, prevent heart attack and sudden death. Patients with heavy coronary stenosis and limited scope can use interventional treatment; those with multi-vessel lesions and left main stem lesions should choose surgical treatment (coronary artery bypass); patients with post-infarction complications such as ventricular rupture, ventricular septal perforation, mitral valve insufficiency and ventricular wall aneurysm must choose surgical bypass surgery.
