Heart bypass surgery, also known as coronary artery bypass grafting, is the most effective treatment for coronary heart disease. One year after surgery, patients should avoid alcohol and smoking.
Alcohol contains a large amount of ethanol, which acts as a vasodilator and excites the sympathetic nerves. It may also cause an increase in heart rate, induce arrhythmias, and aggravate myocardial oxygen consumption.
Drinking alcohol can also lead to varying degrees of spasm in the coronary arteries, aggravating myocardial ischemia and hypoxia. It induces coronary heart disease, angina pectoris and even acute myocardial infarction.
Therefore, patients one year after bypass surgery should not drink alcohol and put their health in danger. Patients should avoid exposure to risk factors that induce coronary heart disease and take responsibility for their own health to prevent disease recurrence and progression.
