Chronic heart failure is a common and frequent disease in clinical practice, often caused by severe myocardial damage, which leads to insufficient myocardial contraction and results in inadequate peripheral blood supply. The primary principles of treatment are to reduce the heart's burden, enhance its contractile strength, decrease the heart's workload, and reduce the returning blood volume to alleviate the heart's burden. Treatment involves using vasodilators to decrease cardiac resistance, positive inotropic drugs to strengthen cardiac contraction, and diuretics and a low-salt diet to reduce cardiac volume and returning blood volume. By employing these methods, the symptoms of chronic heart failure can be improved.
