Coffee is not recommended one year after a heart attack. Even though it has been one year after myocardial infarction, the function of the heart has been affected and cannot be restored to a healthy state, it is still not recommended to drink coffee. Such patients need to eat a light diet, quit smoking and drinking, and pay attention to controlling blood pressure, blood sugar and blood lipids on a daily basis, and should try to avoid eating stimulating foods. As the main ingredient of coffee is caffeine, it can stimulate the sympathetic nerves of the human body and make it excited, leading to faster heart rate and increased myocardial oxygen consumption, further aggravating the burden on the heart, which is not conducive to the recovery of patients with heart attack. Therefore, one year after the occurrence of heart attack also needs to strictly control the diet and carefully observe the body changes. If discomfort occurs immediately consult a doctor and treat according to medical advice.
