alcoholic cardiomyopathy

Alcoholic cardiomyopathy (ACM) is a type of heart disease that arises from chronic alcohol consumption. It is characterized by the weakening and thinning of the heart muscle, affecting its ability to pump blood efficiently.

Causes and Risk Factors:

• Long-term excessive alcohol consumption (>80 g/day over 5 years)
• Direct toxic effect of alcohol on the myocardium
• Physical changes to the heart caused by chronic, long-term abuse of alcohol

Symptoms and Effects:

• Impaired contraction and dilation of one or both ventricles of the heart
• Heart failure, which can affect other parts of the body if severe
• Most common in males between the ages of 45-59 years old

Prevalence and Statistics:

• Estimated incidence of ACM ranges from 1-2% of all heavy alcohol users
• Approximately 21-36% of all non-ischemic cardiomyopathies are attributed to alcohol
• Higher disease burden in males, with a sex ratio of hospital admission at almost 9:1

Classification and Definition:

• Considered a specific disease by the European Society of Cardiology (ESC) and the American Heart Association (AHA)
• Classified among the acquired forms of dilated cardiomyopathy (DCM)

Alcoholic cardiomyopathy, a condition caused by long-term excessive alcohol consumption, can manifest in various ways. The signs and symptoms of this disease are often similar to those seen in other forms of cardiomyopathy.

Common Signs and Symptoms:

• Shortness of breath during physical activity or at rest [6]
• Fatigue or weakness [5][7]
• Swelling in the legs, ankles, and feet due to fluid buildup [3]
• Dizziness or fainting [3]
• Irregular heartbeat or palpitations [2][8]
• Chest discomfort or pain [8]

Additional Symptoms:

• Waking up at night with shortness of breath [5]
• Extreme fatigue, even after resting [5]
• Rapid or irregular pulse [2]
• Ankle swelling and edema [2]

It's essential to note that these symptoms can be similar to those experienced in other heart conditions. A proper diagnosis by a medical professional is necessary for an accurate assessment of alcoholic cardiomyopathy.

Diagnostic Tests for Alcoholic Cardiomyopathy

Alcoholic cardiomyopathy, a type of heart disease caused by excessive alcohol consumption, can be challenging to diagnose due to its non-specific symptoms. However, various diagnostic tests can help confirm the condition.

• Blood tests: Blood tests can provide hints suggesting chronic alcohol abuse and raise suspicion of alcoholic cardiomyopathy in patients with systolic dysfunction. These include:
  • Elevated liver enzymes (alanine aminotransferase and aspartate aminotransferase) [3][11]
  • Increased gamma-glutamyl-transpeptidase (GGT) [10][11]
  • Mean corpuscular volume (MCV) abnormalities [2][10]
• Other diagnostic tests: In addition to blood tests, other diagnostic tests may be used to rule out other causes of heart failure and confirm the diagnosis of alcoholic cardiomyopathy. These include:
  • Echocardiogram: To assess left ventricular function and identify any structural changes in the heart [9]
  • Electrocardiogram (ECG): To evaluate the electrical activity of the heart and detect any abnormalities [9]
  • Cardiac catheterization: To measure blood pressure and flow within the coronary arteries and diagnose any blockages or other issues [9]

Important Note: No laboratory test or finding is diagnostic of alcoholic cardiomyopathy on its own. A combination of medical history, physical examination, and diagnostic tests is typically used to confirm the diagnosis.

Treatment Options for Alcoholic Cardiomyopathy

Alcoholic cardiomyopathy, a condition caused by excessive long-term alcohol use, can be effectively managed with a combination of lifestyle modifications and pharmacological treatment.

• Source control: The primary goal of treatment is to stop or reduce alcohol consumption. This can be achieved through counseling, support groups, and medication-assisted therapy (MAT) [11].
• Trimetazidine: Studies have shown that trimetazidine, a metabolic modulator, can improve heart function in patients with alcoholic cardiomyopathy when used in combination with other conventional heart failure drugs [11].
• Pharmacological treatment for alcohol use disorder: Medications such as disulfiram (ALDH inhibitor) and acamprosate can

Alcoholic cardiomyopathy (AC) is a specific form of dilated cardiomyopathy caused by prolonged and heavy alcohol intake in the absence of other causes [3]. When diagnosing AC, it's essential to consider differential diagnoses that can mimic its symptoms. Here are some conditions that should be ruled out:

• Cirrhotic cardiomyopathy: This condition is associated with liver cirrhosis and can present with similar symptoms to AC [2].
• Other causes of atrial fibrillation: Atrial fibrillation can be a symptom of various conditions, including heart failure, which can be caused by AC. However, it's crucial to rule out other potential causes [2].
• Beriberi: This is a disease caused by thiamine (vitamin B1) deficiency, which can lead to cardiac symptoms similar to those seen in AC [8].

To accurately diagnose AC, healthcare professionals must consider these differential diagnoses and use exclusion criteria. For instance, excessive alcohol consumption can be evidenced through patient history or laboratory tests [4].

In some cases, additional diagnostic tools like cardiac MRI may be helpful in ruling out other conditions such as hypertrophic cardiomyopathy, storage diseases, or inflammatory cardiomyopathy [9].
