You can eat chili peppers after heart stenting, but you should consume them in moderation to avoid aggravating gastrointestinal irritation. Usually, moderate consumption of chili peppers after cardiac stent implantation does not have much effect; however, excessive consumption should be avoided, as well as avoiding spicy chili peppers, as they may stimulate the heartbeat to accelerate, resulting in cardiac ischemia and arrhythmia, and also stimulate the gastrointestinal tract to cause gastrointestinal bleeding and constipation. Secondly, after cardiac stent implantation, it is recommended to have a light diet, consume some fresh vegetables and fruits, and avoid spicy and stimulating foods such as barbecue; meanwhile, moderate exercise is needed to improve the cardiovascular regulation and adaptability. If any discomfort occurs after cardiac stent implantation, one should consult a doctor immediately for treatment.
