Heart failure after one year of dialysis, its probable that heart failure can be relieved if kidney transplantation is done, though it depends on the condition of the heart. Generally speaking, kidney transplantation can better promote the discharge of water and sodium and relieve heart failure, but if the heart has developed organic lesions, simple kidney transplantation may not be effective, and still need to cooperate with anti-heart failure treatment. Dialysis is mainly through small molecules through the semi-permeable membrane diffusion to the principle of water, the body to discharge the size of the molecules, toxins and other substances out of the body, mostly used in renal failure patients. And dialysis for one year leads to heart failure, the probability is because of sodium and water retention caused by kidney failure, leading to heart failure. Kidney replacement can be a better solution to kidney failure, thus promoting the discharge of water and sodium, reducing cardiac afterload and thus relieving heart failure. However, if the heart has developed organic lesions such as cardiac hypertrophy, coronary artery disease, etc., kidney transplantation alone may not be effective and still needs to be combined with anti-heart failure treatment. It is recommended that dialysis patients with heart failure should consult the hospital in time and follow the doctor’s instructions to avoid delaying their condition.
