The 5-year survival rate for patients with heart failure grade III is less than 50%. The presence of heart failure grade III indicates that the patient’s physical activity is significantly limited by the heart’s function, and that less than average activity causes symptoms of heart failure such as fatigue and dyspnea. Patients with heart failure class III can be treated with adjunctive related devices. For patients with heart failure accompanied by reduced left ventricular ejection fraction, previous ventricular fibrillation, cardiac arrest, and hemodynamic instability, a ventricular reversal defibrillator can be implanted as a secondary prophylactic treatment to prolong life. Patients with heart failure who have indications for ventricular resynchronization therapy and are at high risk for sudden death, especially for patients with cardiac insufficiency after myocardial infarction, or ischemic cardiomyopathy, should try to undergo synchronization therapy after implantation of a ventricular defibrillator. Patients can live longer with regular oral medication as prescribed by a physician, close monitoring of intake and output, ensuring water and electrolyte balance, or heart transplantation.
