Patients with coronary heart disease should eat light, easily digestible foods, opt for low-salt and low-fat options, and consume plenty of fresh vegetables and fruits. Foods rich in dietary fiber, such as wheat, oats, and buckwheat, can also be eaten in moderation. Avoid foods high in animal fats and cholesterol, as well as salt-rich preserved items. In addition to dietary adjustments, patients with coronary heart disease should engage in reasonable exercise, effectively control their weight, maintain a good psychological state, and avoid overwork and staying up late, ensuring ample sleep at night. It is important to actively control risk factors such as high blood pressure, diabetes, and high blood cholesterol, provide long-term standardized medication treatment for coronary heart disease, and maintain stability of the condition.
