Heart failure is also called cardiac insufficiency, which is graded into four levels. Grade III is second only to the most severe cardiac insufficiency, and patients will have chest tightness, breathlessness, dyspnea, and enlargement of the liver and spleen, as well as fluid in the abdomen and edema in both lower extremities. Once Class III heart failure occurs, patients often live less than five years. Therefore, after the development of heart failure, it is important to go to the hospital to understand the causes of heart failure, such as heart valve disease, coronary artery disease, cardiomyopathy, etc., through specific examinations, and to give active treatment. In addition to treating these primary causes, cardiac strengthening, diuretic and myocardial nutrition drugs should be given to synergistically extend the patient’s life span.
