What Is Alcoholic Cardiomyopathy? Symptoms, Causes, Diagnosis and Treatment

Electron microscopy reveals mitochondrial enlargement and disorganization, dilatation of the sarcoplasmic reticulum, fat and glycogen deposition, and dilatation of the intercalating discs. Physical examination findings in alcoholic cardiomyopathy are not unique compared with findings in dilated cardiomyopathy from other causes. Elevated systemic blood pressure may reflect excessive intake of alcohol, but not AC per se. Dilated cardiomyopathy secondary to alcohol use does not have a pre-defined exposure time.


Eventually, it is to be hoped that an exact metabolic lesion will be identified so that therapy can be directed toward correcting such a lesion. Alcoholic cardiomyopathy is most common in men between the ages of 35 and 50, but the condition can affect women as well. People with alcoholic cardiomyopathy often have a history of heavy, long-term drinking, usually between five and 15 years. Heavy drinking is alcohol consumption that exceeds the recommended daily limits. A 1- and 4-year follow-up study of 55 men with alcoholism showed that abstinence and controlled drinking of up to 60 g/day resulted in comparable improvement in left ventricular ejection fraction. Ten patients who continued to drink higher amounts of alcohol all died during the follow-up period. Binge drinking induces a systemic inflammatory reaction, which may lead to alcohol-induced myocardial inflammation.

Incidence of alcoholic cardiomyopathy ranges from 1-2% of all heavy alcohol users. It is estimated, approximately 21-36% of all non-ischemic cardiomyopathies are attributed to alcohol. The prevalance of alcoholic cardiomyopathy in addiction units is estimated around %. Overall data with regards to alcohol induced cardiomyopathy is insuffienct and does not illustrate significant available data. In many — if not most — cases, abstaining from alcohol can be enough to help people recover from alcohol-induced cardiomyopathy. In cases where people don’t recover fully by abstaining from alcohol, most people will still see noticeable improvements in their symptoms.


Chest radiographs usually show evidence of cardiac enlargement, pulmonary congestion, and pleural effusions. Other studies and reviews have also quoted quantities similar to those mentioned above, and the type of beverage consumed appeared to be irrelevant.

Alcoholic cardiomyopathy and cardiovascular events – an insight from the Liptov region. Some promising new treatments are targeting the pathways that are involved in the pathogenesis of ACM such as myocyte hypertrophy, cell necrosis and fibrosis, and oxidative stress; however, these are still under investigation. Other deficiencies including nutritional such as thiamine or other toxic materials ingested may lead to additional concomitant complications.

alcoholic cardiomyopathy recovery time-related cardiomyopathy is a type of dilated cardiomyopathy, which is when your heart’s shape changes because its muscles are stretching too much. The effect is much like how a rubber band or spring weakens when stretched too much. Cardiomyopathy is disease in which the heart muscle becomes weakened, stretched, or has another structural problem. The FDA is continuing to investigate and gather more information in an effort to identify whether there is a specific dietary link to development of DCM and will provide updates to the public as information develops.
