Patients with coronary heart disease can eat small amounts of chili peppers according to taste, but they must not eat too much spice. Chili peppers are a spicy, irritating diet, and too much of it may cause gastrointestinal discomfort, such as constipation and damage to the mucous membrane of the gastrointestinal tract. For coronary heart disease requires regular secondary prevention treatment of coronary heart disease, commonly used drugs such as aspirin, clopidogrel, tigretol and so on. Anti-platelet drugs also have the risk of causing mucosal damage to the gastrointestinal tract, and the possibility of gastrointestinal mucosal damage increases when anti-platelet drugs and chili peppers are taken together, so it is not easy for patients with coronary heart disease to consume too much chili peppers. In addition, for patients with coronary artery intervention, the consumption of chili peppers will often cause gastrointestinal discomfort, such as constipation, which will increase the burden of myocardial ischemia and hypoxia, and will have a negative impact on the surgery and the patient’s condition.
