How is a reversible dilated cardiomyopathy corrected?

Vasodilators. Generally, vasodilating medications, such as ace inhibitors or arb's, along with beta-blockers, are the most helpful in patients with dilated cardiomyopathy, with diuretics and nitrates also being of some use. These medications are used to reduce the workload on the heart muscle by reducing oxygen demand of the heart muscle and reducing pressure inside the heart chamber.
