[2] Chronic alcohol consumption leads to the accumulation of toxic metabolites, such as acetaldehyde and reactive oxygen species, in the heart muscle cells.

[3] Additionally, chronic alcohol consumption can lead to deficiencies in essential vitamins and minerals, such as thiamine, magnesium, and selenium, which are important for the proper functioning of the heart.

[7] Chronic consumption of alcohol (defined as greater than 80 g per day for at least 5 years) can lead to multi-organ failure, including myocardial dysfunction.

[7] The exact pathophysiologic mechanism by which chronic consumption of alcohol causes DCM is not well understood, however it's believed that genetic mutation, and mitochondrial damage due to oxidative stress injury may play a role.

Echocardiogram abnormalities and cardiac catheterization or angiogram to rule out coronary artery blockages, along with a history of alcohol abuse can confirm the diagnosis.

The diagnosis of alcoholic cardiomyopathy is typically made based on a combination of the patient's medical history, physical examination, and diagnostic tests.

[8] In addition to the patient's medical history and physical exam, the diagnosis of alcoholic cardiomyopathy is often confirmed with various diagnostic tests.

[8] The prognosis is influenced by several factors, including the amount of alcohol and the time period over which it has been consumed, the presence or absence of dysrhythmias such as atrial fibrillation, and the width of the QRS complex.

Indicators of good prognosis include the following: successfully quitting the consumption of alcohol (associated with decreased hospital admissions), and patient compliance with beta blockers.

[9] The prognosis of alcoholic cardiomyopathy (ACM) varies depending on the severity of the condition, the extent of heart muscle damage, and the response to treatment.

[10] However, with proper treatment, including cessation of alcohol consumption and management of heart failure symptoms, the prognosis can improve significantly.

In addition, people who receive early treatment for ACM, including medication and lifestyle modifications, have a better chance of improving their heart function and overall health.

For instance, individuals with this condition may be at a higher risk of developing blood clots, which can lead to heart attacks, strokes, or other serious cardiovascular events.

Medications may include ACE inhibitors, beta blockers, and diuretics which are commonly used in other forms of cardiomyopathy to reduce the strain on the heart.
