Both heart failure and kidney failure are serious conditions. Heart failure, also known as heart failure, is a metabolic syndrome in which various factors lead to impaired pump function of the heart and the heart cannot discharge enough blood to meet the basic needs of the peripheral tissues, and patients can suffer kidney failure as a direct result of heart failure. In patients with chronic renal failure, there is also an increased anterior and posterior load on the heart, which can lead to further heart failure. Therefore, if a patient presents with both renal failure and heart failure and has right heart failure or total heart failure, it is a fairly serious condition with a mortality rate of up to 50% within five years and 50% within one year in severe cases. In patients with renal failure combined with heart failure, there is often severe renal insufficiency accompanied by severe total heart insufficiency, and systemic therapy must be administered systemically at this time.
