Prevention of renal dysfunction in patients with heart failure: new understanding and research progress

A close relationship exists between renal dysfunction and heart failure (HF) and 25% of patients with chronic HF are complicated by renal dysfunction. Among the patients with acute HF, 64% are complicated by acute renal damage and these patients often have a history of renal dysfunction. How to prevent renal dysfunction in HF patients is of great research interest for cardiologists. In recent years, cardiologists have offered a variety of measures to prevent renal dysfunction in patients with HF and some progress has been achieved. In this article some new understanding and research progress in the prevention of renal dysfunction in patients with heart failure were reviewed.
