Most myocardial ischemia is caused by atherosclerosis leading to narrowing of the coronary arteries, which triggers insufficient blood and oxygen supply to the heart. Once symptoms of myocardial ischemia appear, one should actively seek medical attention and be actively treated under the guidance of a doctor. There are no specific requirements for patients in terms of fruits, and there are more than three kinds of fruits suitable for eating. Prolonged myocardial ischemia affects the function of the heart, when it leads to low levels of potassium ions in the blood. Therefore, it is recommended that during and after treatment, you can choose to eat fruits rich in potassium ions and vitamins in moderation, including kiwi, apple, banana, mango, hawthorn, cherry, etc. In addition, selenium supplementation can, to a certain extent, resist atherosclerosis, reduce blood viscosity, increase coronary blood flow and reduce the degree of myocardial damage. A class of foods with high selenium content include oysters, fresh shellfish, shrimp skin, sea shrimp, etc. Patients are advised to eat less and more meals and avoid overfeeding at one time to avoid increasing the load on the heart and aggravating the myocardial ischemia. If patients with myocardial ischemia are combined with diabetes, they need to avoid fruits with high sugar content, such as persimmon, cinnamon and honeydew melon, in order not to promote atherosclerosis and lead to the development of arterial stenosis. Patients should pay attention to maintain a balanced diet with low sodium, low sugar and low fat. Animal liver, doughnuts, pickles, fried cakes and fatty meat should be avoided to avoid aggravating coronary artery atherosclerosis and inducing myocardial ischemia.
