For patients with myocardial ischemia, it is not recommended to cite alcoholic beverages, including red wine, after drinking alcoholic induced patients will experience sympathetic overexcitation, increased myocardial contraction, accelerated heart rate, increased myocardial oxygen consumption, and arrhythmia. Patients will also have insufficient blood supply and oxygen supply to the heart, and at this time, for patients with myocardial ischemia, a series of clinical symptoms and clinical manifestations such as obvious chest tightness, shortness of breath and palpitations will occur. In addition, after drinking a large amount of red wine, the ethanol in alcohol will decompose and release acetaldehyde, which will open the permeability of capillaries and cause fluctuations in blood pressure, leading to a drop in blood pressure and then an increase, which will further increase the load on the heart and cause a significant increase in the symptoms of myocardial ischemia. In addition, if you drink red wine for too long or drink a lot of red wine for a long time, it can lead to alcoholic myocardial injury.
