. Due to the direct toxic effects of alcohol on heart muscle, the heart is unable to pump blood efficiently, leading to heart failure. It can affect other parts of the body if the heart failure is severe. It is most common in males between the ages of 35 and 50.

Signs and symptoms

Signs and symptoms presented by the occurrence of alcoholic cardiomyopathy are the result of the heart failing and usually occur after the disease has progressed to an advanced stage. Therefore, the symptoms have a lot in common with other forms of cardiomyopathy. These symptoms can include the following: * Ankle, feet, and leg swelling ( edema) * Overall swelling *

Treatment

Treatment for alcoholic cardiomyopathy involves lifestyle changes, including complete abstinence from alcohol use, a low sodium diet, and fluid restriction, as well as medications. Medications may include

ACE inhibitors Angiotensin-converting-enzyme inhibitors (ACE inhibitors) are a class of medication used primarily for the treatment of high blood pressure and heart failure. They work by causing relaxation of blood vessels as well as a decrease in blood volume ...

beta blockers Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms, and to protect the heart from a second heart attack after a first heart attack ( secondary prevention). They are ...
