They target specific processes that contribute to the development of alcoholic cardiomyopathy. These include myocyte hypertrophy (abnormal enlargement of heart cells), cell death, fibrosis (the formation of excess fibrous connective tissue), and oxidative stress. However, these promising treatments are still being researched and aren’t available yet. The condition’s death rates are higher in males than in females and are more prevalent among black individuals compared to the white population.
The importance of addressing social isolation in recovery
Alcoholic cardiomyopathy is a type of dilated cardiomyopathy where chronic alcohol abuse leads to the dilation and weakening of the heart chambers, particularly the ventricles. The condition manifests with symptoms such as shortness of breath, fatigue, swelling in the legs and abdomen, and irregular heartbeats. The primary cause is the toxic effects of alcohol on the heart muscle cells, leading to their degeneration and impaired function. Excessive alcohol intake may result in increased systemic blood pressure in a dose-response relationship, and this may contribute to chronic myocardial dysfunction. Patients who consume more than two drinks per day have a 1.5- to 2-fold increase in hypertension compared with persons who do not drink alcohol, and this effect is most prominent when the daily intake of alcohol exceeds five drinks. Because hypertension may directly contribute to LV dysfunction, this may be a confounding comorbidity in persons who abuse alcohol, and it should be differentiated from pure forms of alcoholic cardiomyopathy.
How Does Alcohol Cause an Enlarged Heart? The Pathophysiology Explained

The pathophysiology of AC involves a combination of direct toxic effects of alcohol on the myocardium, oxidative stress, mitochondrial dysfunction, and genetic susceptibility. Alcoholic cardiomyopathy is most common in men between the ages alcoholic cardiomyopathy symptoms 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. In many — if not most — cases, abstaining from alcohol can be enough to help people recover from alcohol-induced cardiomyopathy.
Prognosis of alcoholic cardiomyopathy
- These biological nuances underscore the need for gender-sensitive approaches to alcohol education and cardiovascular screening.
- To assess the quality and validity of the included studies, we performed a critical appraisal using appropriate tools such as the Newcastle-Ottawa Scale for observational studies or the Cochrane Risk of Bias tool for clinical trials.
- They aim to control oxidative damage, myocyte hypertrophy, interstitial fibrosis, and persistent apoptosis.
- Abstaining from alcohol may help some people recover, but others will need medication or even surgery.
The prognosis for individuals diagnosed with alcoholic cardiomyopathy varies significantly based on several factors, including the duration and severity of alcohol use. If diagnosed early and coupled with alcohol abstinence, individuals can see marked improvements in their health. Evidence indicates that stopping alcohol consumption leads to improved outcomes, including reduced hospital admissions and heart size as seen through echocardiograms 1. Alcohol-induced cardiomyopathy is a heart muscle disease caused by chronic alcohol consumption since no other origin is known. This heart disease is characterized by impaired contraction and dilation of one or both ventricles of the heart.
Cardiotoxic Effects of Alcohol
Regular physical activity is also beneficial for maintaining cardiovascular health. Doctors at NYU Langone recommend these lifestyle changes to help manage symptoms and prevent further deterioration of heart function 5. The relationship between alcohol and heart failure has been extensively studied. According to clinical research, most of the symptoms of alcoholic-induced cardiomyopathy occur when the disease is irreversible and advanced and may start with signs of congestive heart failure. Supplements are typically used alongside other treatments to support overall health and improve heart function, especially in patients who have been malnourished due to alcohol use. Patients may notice improvements in energy levels and well-being within a few weeks.
What are signs and symptoms of Alcoholic Cardiomyopathy (Alcohol-related Heart Damage)?
Nutritional deficiencies are a critical, yet often overlooked, component in the development of alcoholic cardiomyopathy. Chronic alcohol use impairs the absorption of essential vitamins and minerals like thiamine, magnesium, selenium, and coenzyme Q10, all of which are vital for cardiac energy metabolism. Deficiencies in these nutrients can exacerbate mitochondrial dysfunction and oxidative stress in heart cells, hastening myocardial weakening and dilation.
- Dizziness is reported in about 20-30% of patients with alcoholic cardiomyopathy.
- This heightened vulnerability is partly due to differences in body fat composition, alcohol dehydrogenase activity, and hormonal interactions with ethanol.
- The heart muscle weakens and becomes thinner over time due to alcohol abuse, adversely affecting its capacity to efficiently pump blood.
- You will receive the first heart failure and transplantation email in your inbox shortly.
- Alcohol-induced cardiomyopathy is a condition that can have major impacts on your life over time.
Alcoholic cardiomyopathy is a condition that weakens your heart and its ability to pump blood. People who suffer from alcohol dependence or alcohol use disorder (AUD) are at risk of developing this condition. To avoid alcoholic cardiomyopathy, abstain from alcohol or drink in moderation. Because alcoholic cardiomyopathy is influenced by how much alcohol you drink, lessening your alcohol intake can reduce the likelihood of developing the condition. You can experience heart failure if alcohol-induced cardiomyopathy is left untreated or worsens.

The left ventricular end-diastolic diameters show a significant increase in such patients compared to healthy individuals in the same age and weight. Moreover, there is a decrease in the left ventricular mass index and ejection fraction, falling below the normal range. Diastolic dysfunction, characterized by impaired left ventricular relaxation and reduced diastolic filling capacity, serves as an early indicator of ACM. Ventricular dilatation is the first echocardiographic change seen in alcohol use disorder patients, coming before diastolic dysfunction and hypertrophy.
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. Subjects with a shorter period of alcohol abuse, from 5 to 10 years, had a significant increase in left ventricular diameter and volume compared to the control group. However, a systolic impairment was not found as the years of alcoholic abuse continued. Experts know that alcohol’s effects on the heart are that excessive drinking can weaken the heart over time, affecting its muscle and ability to pump blood. When the heart struggles to pump blood as normal, it can begin expanding and become enlarged, causing significant strain marijuana addiction and damage and leading to heart failure. Alcoholic cardiomyopathy is one type of dilated cardiomyopathy (DCM), the most common type.
