In the second study, Gavazzi led a multicentre study in which, from 1986 to 1995, 79 patients with ACM and 259 patients with DCM were recruited10. Transplant-free survival after 7 years was worse among patients with ACM than among those with DCM (41% vs 53%). Among patients who continued drinking heavily, transplant-free survival was significantly worse than in non-drinkers (27% vs 45%). In this review, we evaluate the available evidence linking alcohol consumption with HF and DCM. A new test that looks at proteins in the blood could offer a more accurate diagnosis of heart failure.
- If diagnosed early and alcohol consumption stops completely, heart function can improve or even return to near normal.
- Electrocardiographic findings are frequently abnormal, and these findings may be the only indication of heart disease in asymptomatic patients.
- Some studies have shown that the combination of carvedilol and trimetazidine with other traditional heart failure medications is effective 1-3,7-11,16-20.
How does this condition affect my body?
In summary, recognizing these symptoms—fatigue, shortness of breath, swelling, irregular heartbeat, and chest pain—is crucial for early intervention in alcoholic cardiomyopathy. Each sign reflects the heart’s declining ability to function, with progression often tied to the duration and amount of alcohol consumption. While lifestyle changes like abstaining from alcohol and adopting a heart-healthy diet can slow deterioration, advanced cases may require medications (e.g., beta-blockers, diuretics) or even devices like pacemakers. The key is acting before irreversible damage occurs—because when it comes to the heart, time is muscle. Education and awareness play a significant role in preventing alcohol cardiomyopathy. Individuals should understand the direct link between excessive alcohol consumption and heart damage, as well as the long-term consequences of ignoring early warning signs.
Clinical manifestations and diagnosis of alcohol-induced cardiomyopathy
In patients with DC, if additional questions remain after a history is obtained and noninvasive testing is performed, cardiac catheterization may be used to help exclude other etiologies of heart failure. To identify the causative agent of AC, investigators administered ethanol to rats pretreated with inhibitors of ethanol metabolism. Use of ethanol alone or ethanol with an alcohol dehydrogenase inhibitor resulted in a 25% decrease in protein synthesis. When the rats were given an inhibitor of acetaldehyde dehydrogenase to increase levels of the ethanol metabolite acetaldehyde, an 80% decrease in protein synthesis occurred. Based on these data, acute ethanol-induced injury appears to be mediated by ethanol and acetaldehyde; the latter may play a more important https://designinrhythm.com/chrissy-teigen-shares-honest-insights-on-her-52/ role.
General Health
Cardiomyopathy is a heart condition that causes malfunctioning of the cardiac muscle called the myocardium, because of the stiffening and the expansion of the heart. The cardiovascular changes will eventually lead to a drastic reduction in the pumping mechanism of the heart, which in turn is a major cause of irregular heartbeats. Cardiomyopathy is a heart disease that intensifies in nature and when it is induced due to heavy alcohol use, it is referred to as alcoholic cardiomyopathy. The immediate aftermath of this is the weakening of the heart and related structures, reduced blood supply throughout the body, and failure to maintain a normal and steady electrical rhythm.
Prevention of Alcohol-Induced Cardiomyopathy
It often occurs due to the heart’s reduced ability to pump blood effectively, leading to inadequate oxygen supply to the heart muscle itself. This pain, known as angina, can feel like pressure, tightness, or squeezing in the chest and may radiate to the arms, neck, or back. Chest pain is a red flag that the heart is under significant stress and requires urgent evaluation to prevent further damage or life-threatening complications.
- The latest two papers to be published, unlike previous papers, reported worse outcomes for ACM patients compared to DCM patients.
- Other health problems you have can also affect your case, especially if those problems have any connection with alcohol use.
- This can cause you to develop an irregular heartbeat, called atrial fibrillation, which can increase your risk of stroke, heart attack and heart failure.
- Most people who develop alcohol-induced cardiomyopathy have a history of heavy drinking—especially those who have been drinking heavily for 5 to 15 years.
These habits can compound alcohol’s effects on the heart and increase the likelihood of developing heart disease. The focus of this review is on the effects of alcohol on the myocardium and its role as a cause of heart failure due to dilated cardiomyopathy (DC). The pathophysiology of AC involves a combination of direct toxic effects of alcohol on the myocardium, oxidative stress, mitochondrial dysfunction, and genetic susceptibility. Alcohol and the substances it changes into inside the body can harm the heart. At first, the heart’s ability to pump blood effectively can decrease because of alcohol, but this can get better if a person stops drinking.
Management and Treatment
A well-functioning heart is essential for maintaining the overall health of virtually every system in the body. Therefore, when the heart’s efficiency is compromised due to alcohol-induced cardiomyopathy, the impacts are pervasive and consequential. Common symptoms of alcoholic cardiomyopathy, such as persistent shortness of breath, unrelenting fatigue, and noticeable swelling in the legs, serve as distress signals, indicating that the heart is crying out for help. Recognizing these signals and interpreting them as an urgent call to action is a critical step towards addressing the issue. Ballester specifically analysed the effects of alcohol withdrawal on the myocardium using antimyosin antibodies labelled with Indium-11172.
What are the treatment options for alcoholic cardiomyopathy?
- However, hypertensive heart disease is linked to long-term high blood pressure, while alcoholic cardiomyopathy is related to chronic alcohol use.
- Orthopnea, or difficulty breathing while lying flat, affects around 40-50% of patients with alcoholic cardiomyopathy.
- Treatment for this condition starts with helping you reduce your alcohol intake or stop drinking entirely.
Alcoholic cardiomyopathy is a form of dilative cardiomyopathy, in which the heart enlarges and weakens. Excessive alcohol consumption directly damages the heart cells, causing the walls to thin and reducing the heart’s ability to pump blood. As the disease progresses, the reduced blood flow affects the entire body, causing fatigue, difficulty breathing, and swelling in the legs or abdomen. The first and most critical step in treating alcohol-induced cardiomyopathy is complete abstinence from alcohol. Without this commitment, other interventions will be substantially less effective. Beyond abstinence, treatment strategies typically encompass a combination of medications designed to manage symptoms, improve heart function, and prevent further disease progression.

Studies show that complete cessation of alcohol can lead to partial or even full recovery of heart function in some cases, particularly if the condition is caught early. For individuals struggling with addiction, support systems such as counseling, support groups like Alcoholics Anonymous, or medically supervised detoxification programs are essential to ensure long-term sobriety. Alcoholic cardiomyopathy, a condition where chronic alcohol abuse weakens the heart muscle, often flies under the radar until symptoms become severe. Diagnosing it early is crucial, as timely intervention can slow progression and improve outcomes. The diagnostic process is multifaceted, blending medical history, physical exams, imaging tests, and blood work to paint a comprehensive picture of heart function.
Studies show that prolonged intake of more than 80 grams of alcohol per day (roughly equivalent to 5-6 standard drinks) significantly increases the risk of developing alcoholic cardiomyopathy. This condition is not an overnight phenomenon; it is the culmination of years of consistent overconsumption, where the heart’s ability to pump blood efficiently is compromised, leading to heart failure. Excessive alcohol consumption, particularly over a decade or more, directly weakens and thins the heart muscle, leading to alcoholic cardiomyopathy. This condition disrupts the heart’s ability to pump blood effectively, often resulting in symptoms like fatigue, shortness of breath, and swelling in the legs. For context, studies suggest that consuming more than 80 grams of alcohol daily (roughly 6–7 standard drinks) for men and 40 grams (3–4 drinks) for women significantly Twelve-step program increases the risk of developing this disease. The toxicity of alcohol and its byproducts damages heart cells, causing them to enlarge and lose functionality over time.
The first study, which specifically focused on the amount of alcohol necessary to cause ACM, was conducted by Koide et al20 in 1975. The authors examined the prevalence of cardiomegaly by means of chest x-rays and related it to alcohol consumption among a consecutive series of Japanese males of working age. They found that 2 of the 6 individuals (33%) whose alcohol consumption exceeded 125 mL/d had cardiomegaly.
One of the few papers analysing genetic susceptibility in ACM was published by Fernández-Solà et al64 in 2002. He compared the prevalence of different polymorphisms of the angiotensin-converting enzyme gene in 30 ACM patients and in 27 alcoholics with normal ventricular function. Furthermore, 89% of the alcoholics with a DD genotype developed ACM, whereas only 13% of those with an II or ID genotype alcoholic cardiomyopathy symptoms developed this condition.
