Diabetic patients with heart failure and renal failure have a relatively short life expectancy of less than 5 years, depending on the patient’s condition. Renal failure is a prominent complication of diabetic nephropathy, and more patients need dialysis to maintain basic life, but the dialysis process may also cause serious infections, heart and lung failure or gastrointestinal bleeding, cerebral hemorrhage and other cases of sudden death. In addition, the heart function of diabetic patients is also poor, because long-term diabetes affects the small arteries of the patient’s heart muscle more, which can cause ischemia and necrosis of heart muscle cells, resulting in heart infarction or post-infarction heart failure, which can also seriously affect the patient’s quality of life and lead to a significantly shorter life expectancy.
