Alcohol abstinence vs persistent alcohol consumption in alcoholic cardiomyopathy: impact on long-term prognosis European Heart Journal

In some cases, even just reducing alcohol intake to light or moderate levels can also lead to improvements. However, not drinking at all is still the best course of action whenever possible. Diastolic dysfunction is the earliest sign of ACM and is usually seen in approximately 30% of patients with a history of chronic alcohol abuse with no evidence of systolic dysfunction nor left ventricle hypertrophy. The postulated mechanism includes mitochondria damage, oxidative stress injury, apoptosis, modification of actin and myosin structure, and alteration of calcium homeostasis.

This observation led to the erroneous belief that alcohol is an immediate coronary vasodilator. Symptomatic relief of angina could be through the anesthetic effect of ethanol or through peripheral vasodilation, which could transiently reduce oxygen demand of the heart. Clinical observation confirmed that several days to weeks of drinking show higher and weeks of abstinence lower pressures. Alcohol intake may also interfere with the drug and dietary treatment of hypertension. This altogether supports a causal relationship between alcohol consumption and a hypertensive state.

What Is Alcoholic Cardiomyopathy?

Patients with ACM and who remain abstainers during follow-up exhibit better outcomes and higher LVEF improvement in comparison to non-abstainers. These findings should help to inform lifestyle modification for patients with ACM. Healthwise, Incorporated, disclaims any warranty or liability for your use of this information. Another puzzling aspect of the recent spike in DCM cases is that they have occurred just in the last few years.

A 1- and 4-year follow-up study of 55 men with alcoholism showed that abstinence and controlled drinking of up to 60 g/day (4 drinks) resulted in comparable improvement in left ventricular (LV) ejection fraction. Ten patients who continued to drink higher amounts of alcohol all died during the follow-up period. Alcoholic cardiomyopathy can present with signs and symptoms of congestive heart failure.

Recent Activity

Vet-LIRN is currently evaluating the heart histopathology for two of the deceased dogs. The initial and 1 to 2-month blood and urine samples for 14 and 10 dogs, respectively, have been tested and are being evaluated. The FDA is still gathering information to better understand if (and how) taurine metabolism (both absorption and excretion) may have a role in these reports of canine dilated cardiomyopathy. If a family member has dilated cardiomyopathy, talk to your health care provider.

Can I exercise with alcoholic cardiomyopathy?

Stay Active. Daily light exercise is safe for most people with cardiomyopathy and heart failure and can help them to manage symptoms. Over time, it can reduce heart rate and blood pressure.

As of April 30, 2019, CVCA and Vet-LIRN have collected initial samples from 14 dogs, and 1 to 2-month samples from 10 dogs. Though they aren’t causes of alcohol-induced cardiomyopathy, other lifestyle choices can make it worse. These include using recreational drugs (especially those that affect your heart, such as cocaine) and tobacco alcoholic cardiomyopathy is especially dangerous because (which has major negative effects on your heart, lungs and circulatory system). While alcohol-induced cardiomyopathy comes from long-term alcohol abuse, there’s no universal limit or number that means you’ll develop it. However, researchers have pinpointed certain behaviors that make it more likely you’ll develop this condition.

Cardiovascular Research

The number of years and amount of alcohol it takes to develop this disease is unclear, although some researchers estimate at least five years of daily drinking can significantly increase a person’s risk for ACM. Consecutive patients admitted to a HF clinic from 2001 to 2020 with ACM were included. The primary endpoint was the composite of all-cause death or HF hospitalization. Changes in LVEF at 1- and 3-years follow-up according to discontinuation of alcohol consumption was also analyzed. Multivariable Cox regression analyses were performed using the competing risk strategy for the secondary endpoint.

  • On ECG, unspecific abnormalities like complete or incomplete left bundle branch block, atrioventricular conduction disturbances, alterations in the ST segment, and P wave changes can be found comparable to those in idiopathic DCM [113].
  • Cardiomyopathy is a heart muscle disease that occurs when the heart muscle is thicker or stiffer than it is supposed to be.
  • Based on these data, acute ethanol-induced injury appears to be mediated by ethanol and acetaldehyde; the latter may play a more important role.
  • What you should expect with this condition depends strongly on several factors.
  • This usually involves certain types of medications that treat heart rhythm problems or other symptoms of heart failure.
  • Manhattan Cardiology is the premier facility for cardiac testing and preventive treatment in New York.

Chronic alcohol consumption can cause multi-organ damage including myocardial dysfunction. There are no specific targeted histological or immunological biomarkers for the diagnosis of alcohol-induced cardiomyopathy. Various pathophysiological mechanisms have been postulated in the development of cardiomyopathy however one key factor undergoing active research is the role of genetic mutation and susceptibility to develop cardiomyopathy. Cardiomyopathy itself is heart disease with several potential causes and risk factors that don’t involve alcohol but may be related to other heart conditions or health behaviors. The exact cause of cardiomyopathy, especially in younger adults and children, can be challenging to determine.

Nutritional causes of “alcoholic” cardiomyopathy

Pulmonary rales signify pulmonary congestion secondary to elevated left atrial and left ventricular end-diastolic pressures. Jugular venous distention, peripheral edema, and hepatomegaly are evidence of elevated right heart pressures and right ventricular dysfunction. Alcohol abuse has a toxic effect on many of your organs, including the heart. When it can’t pump out enough blood, the heart starts to expand to hold the extra blood. Eventually, the heart muscle and blood vessels may stop functioning properly due to the damage and strain.

To make a diagnosis, your doctor will perform a physical examination and ask you about your medical history. In general, you should talk to your healthcare provider if you notice changes in your symptoms over time, especially if they are starting to affect your normal life and routine. However, you should talk to your healthcare provider about symptoms that mean you should call their office because each case is different. You should also follow your doctor’s guidance and advice on any treatments you receive.

Instead, a proper diet and regular exercise are better ways to maintain good heart health. The AHA also reports that any potential benefits that red wine may create can be obtained from other non-alcoholic sources, such as grape juice. The pathologic and histologic findings of alcoholic cardiomyopathy (AC) are essentially indistinguishable from those of other forms of dilated cardiomyopathy (DC). Findings from gross examination include an enlarged heart with 4-chamber dilatation and overall increased cardiac mass. Histologically, light microscopy reveals interstitial fibrosis (a finding that has been shown to be prevented by zinc supplementation in the mouse model), myocyte necrosis with hypertrophy of other myocytes, and evidence of inflammation. Electron microscopy reveals mitochondrial enlargement and disorganization, dilatation of the sarcoplasmic reticulum, fat and glycogen deposition, and dilatation of the intercalating discs.
