What is the use of vasodilators in heart failure?

The main application of vasodilators in heart failure is sodium nitroprusside, nitroglycerin, isosorbide mononitrate, etc.

Heart failure is a syndrome formed by impaired cardiac pumping function and inability to meet the metabolic needs of the body. Vasodilators can dilate blood vessels, reduce vascular resistance, help reduce ventricular pre-and (or) afterload, and then improve cardiac output. Clinically, vasodilators commonly used in patients with heart failure are sodium nitroprusside, nitroglycerin, isosorbide mononitrate, etc., which can help relieve symptoms such as dyspnea and angina pectoris after using drugs. Vasodilators are also used in the long-term treatment of heart failure to help slow the progression of the disease. It is

important to note that patients should take them under the guidance of their doctor.
