Red wine is not recommended for patients with myocardial ischemia. Red wine will have a certain effect on the nervous system and blood vessels, and is not conducive to the recovery of patients with myocardial ischemia. After drinking red wine, patients will experience sympathetic over-excitement, which will increase myocardial contractility, accelerate heart rate, increase myocardial oxygen consumption, and have the possibility of arrhythmia. Patients may also also experience insufficient blood and oxygen supply to the heart. At this time, patients with myocardial ischemia will experience a series of clinical symptoms and manifestations such as obvious chest tightness, shortness of breath, palpitations (accelerated heartbeat, often accompanied by panic). In addition, after drinking a large amount of red wine, ethanol in alcohol will release acetaldehyde, which will open the permeability of capillaries and cause fluctuations in patients’ blood pressure, causing it to first fall and then rise, further increasing the load on the heart and further aggravating the symptoms of myocardial ischemia significantly. Long-term consumption of red wine or long-term large amounts of red wine will lead to patients with alcoholic myocardial injury. It is recommended that patients with myocardial ischemia go to the hospital in time and follow the doctor’s instructions to cooperate with the treatment.
