Chronic heart failure is one of the most common complications of various organic heart diseases, and there are many causes of chronic heart failure. The main reason is due to primary diseases that have not been effectively treated. Long-term myocardial ischemia, hypoxia, excessive fatigue, emotional excitement, overeating, too full, constipation, and other reasons increase the cardiac burden, leading to chronic heart failure. People with organic heart disease must treat the primary disease under the guidance of a doctor. At the same time, pay attention to rest, avoid emotional excitement, eat easily digestible food, maintain a low-salt, low-fat diet, and ensure smooth bowel movements to prevent increasing the cardiac burden and causing heart failure.
