Alcoholic Cardiomyopathy: Overview, Cardiac Effects of Alcohol, Quantity of Alcohol Intake in Cardiac Disease

This article will discuss the risk factors, symptoms, diagnostic tests, medications, procedures, and lifestyle changes that can help manage the condition. The postulated mechanism includes mitochondria damage, oxidative stress injury, apoptosis, modification of actin and myosin structure, and alteration of calcium homeostasis. Studies have shown an increase in reactive oxygen species (ROS) level in myocytes following alcohol consumption and thus causes oxidation of lipids, proteins, and DNA leading to cardiac dysfunction. These changes are related to both direct alcohol toxicity on cardiac cells and the indirect toxicity of major alcohol metabolites such as acetaldehyde.

• This ethanol misuse at high consumption rates causes a variety of health problems, ethanol being the sixth most relevant factor of global burden of disease and responsible for 5.3% of all deaths 5.
• And while in some respect males, on the whole, may tolerate more alcohol because of generally larger body size, that’s not the whole story.
• Askanas et al21 found a significant increase in the myocardial mass and of the pre-ejection periods in drinkers of over 12 oz of whisky (approximately 120 g of alcohol) compared to a control group of non-drinkers.
• Once free from alcohol, substance abuse treatment and medical treatments for alcoholic cardiomyopathy can begin.

Laboratory tests

• Transplant-free survival after 7 years was worse among patients with ACM than among those with DCM (41% vs 53%).
• In another study on this topic, Lazarević et al23 divided a cohort of 89 asymptomatic individuals whose consumption exceeded 80 g/d (8 standard units) into 3 groups according to the duration of their alcohol abuse.
• Ethanol may induce changes in nuclear regulation of transcription with a dose-dependent translocation of NFkB into the nucleus 106.
• However, if alcoholic cardiomyopathy is caught early and the damage isn’t severe, the condition can be treated.

Structurally, hypertrophy of myocytes is seen in the early stages to avoid contractile depression 52,107,125. Myocytolysis progressively develops, disturbing the sarcomere contractile system. The heart output is progressively lower in a dose-dependent relationship with the lifetime accumulated total dose of alcohol consumed 38. Several alcoholic cardiomyopathy growth factors and cardiomyokines exert an autocrine or paracrine effect that tries to compensate for this heart damage 119,133. Antioxidant, anti-inflammatory, anti-apoptotic, and antifibrogenic mechanisms try to avoid myocyte necrosis and heart fibrosis 14,30,58. The final result is that achieved from the equilibrium between the degree of damage and the capacity of heart repair mechanisms in each specific individual 31,56.

Alcoholic Cardiomyopathy Treatment

In the 1950s, evidence began to emerge that supported the idea of a direct toxic myocardial effect of alcohol, and research during the last 35 years has been particularly productive in characterizing the disease entity of alcoholic cardiomyopathy (AC). Palpitations, or the sensation of a rapid or irregular heartbeat, affect around 30-40% of patients with alcoholic cardiomyopathy. These sensations are often caused by arrhythmias, which occur when alcohol-induced damage disrupts the heart’s electrical system. Palpitations can be alarming and may be accompanied by other symptoms such as dizziness, chest pain, or shortness of breath. While palpitations are not always dangerous, they should be evaluated by a healthcare provider to determine their underlying cause. The risk of developing alcoholic cardiomyopathy increases with age, particularly in individuals who have been drinking heavily for many years.

How to Know if You Might Have Ischemic Heart Disease vs Alcoholic Cardiomyopathy

Anticoagulants are typically prescribed for patients with irregular heartbeats or a history of blood clots. Regular blood tests are needed to ensure the medication is working safely and effectively. Anyone with concerns about alcohol consumption or heart health needs to consult a doctor for https://ecosoberhouse.com/ further advice and guidance. Around 40–80% of people with ACM who continue drinking alcohol die within 10 years of their diagnosis. Without an adequate supply of blood and oxygen, the body’s organs and tissues can no longer function properly.

Health & Wellness

Cardiac MRI may be helpful in the differential diagnosis to hypertrophic cardiomyopathy, storage diseases, and inflammatory alcoholism cardiomyopathy. An appointment with a medical professional will be needed to diagnose alcoholic cardiomyopathy, and you may be referred to a cardiology department. All of these symptoms contribute to the pathophysiology of alcoholic cardiomyopathy. The Centers for Disease Control and Prevention (CDC) expanded that definition to include alcohol use that is more than seven drinks per week for women and 14 per week for men. Although anticoagulation may be of benefit to patients with profound LV dysfunction and atrial fibrillation, the risks must be weighed heavily in this patient population. Electrocardiographic findings are frequently abnormal, and these findings may be the only indication of heart disease in asymptomatic patients.

They demonstrated a much higher catalase activity among rats suffering from ACM. This may be explained by the fact that the increased catalase activity in those who have a long history of alcohol abuse may represent a protective and adoptive reaction to the persistent high ethanol levels 11. Dizziness is reported in about 20-30% of patients with alcoholic cardiomyopathy. It can occur when the heart is unable to pump enough blood to the brain, leading to lightheadedness or a sensation of spinning. Dizziness may also be related to arrhythmias or low blood pressure, both common in patients with weakened heart function. In some cases, dizziness can lead to fainting, particularly during episodes of irregular heartbeat.
