Alcoholic cardiomyopathy: MedlinePlus Medical Encyclopedia Image

Many people know that long-term alcohol abuse canaffect the liverand cause it to fail. However, other organs, including the heart, are also at risk whenalcohol abuseis heavy and chronic. Alcohol consumption can lead to a heart condition calledalcoholic cardiomyopathy, which may progress to congestive heart failure if left untreated. Regional wall motion abnormalities are not uncommon, but they are usually less prominent than those observed in persons with ischemic heart disease. Hypertension due to alcohol may be a confounding comorbidity in that it may contribute to LV dysfunction; therefore, LV dysfunction due to hypertension must be differentiated from pure AC. We reviewed the effects of ethanol on the cardiovascular system in 1996 , including aspects of inflammation , rhythm disturbances , and hypertension . Chronic alcohol consumption can cause multi-organ damage including myocardial dysfunction.

  • Alcoholic cardiomyopathy is a condition where your heart changes shape because of long-term heavy alcohol use.
  • Hypertrophic obstructive cardiomyopathy a form of hypertrophic cardiomyopathy in which the location of the septal hypertrophy causes obstructive interference to left ventricular outflow.
  • Alcoholic cardiomyopathy can present with signs and symptoms of congestive heart failure.
  • Many changes can be observed including premature atrial or ventricular contractions, supraventricular tachycardias, atrioventricular blocks, bundle branch blocks, QT prolongation, non-specific ST and T wave changes and abnormal Q waves.
  • Guillo and colleagues evaluated 14 patients with AC over a 3-year period with serial examinations, electrocardiograms , stress tests, echocardiograms, and MUGA scans.
  • Though they aren’t causes of alcoholic cardiomyopathy, other lifestyle choices can make it worse.

In patients with chronic alcohol use disorders and severe heart failure prognosis is poor, since continued alcohol abuse results in refractory congestive heart failure. Death might also be sudden due to arrhythmias, heart conduction block, and systemic or pulmonary embolism. This was an excellent result long before ACE inhibitors or betablockers were available for heart failure treatment . Alcohol consumption is the third leading lifestyle-related cause of death for people in the US, behind tobacco and improper diet/lack of physical activity, and is responsible for 3.8% of all deaths globally .

Alcoholic cardiomyopathy: Cytotoxicity of alcohol on heart muscle

Specialized residential alcohol addiction rehab programs can provide a structured and stable environment where trained professionals can help to manage both alcoholism and medical illness complications and disorders. It is important to catch alcoholic cardiomyopathy as soon as possible, as a complete reversal of the disease may be possible if treatment and abstinence begin before fibrosis sets in. Treatment for alcoholic cardiomyopathy often includes programs designed to help a person withdraw from and stop drinking alcohol. Globally, Eastern Europe has been identified as the region with the highest levels of alcohol-related health damage and mortality [25–27]. More than 90% of countries in the region consumed more than two litres of anhydrous alcohol per capita per year . Despite the high burden of alcohol harm and mortality in Eastern Europe, very few policies had been implemented. Moreover, most countries did not advertise the dangers of excessive alcohol consumption and related laws and regulations on TV, radio or the Internet.

alcoholic cardiomyopathy

The outlook for people with alcoholic cardiomyopathy varies depending on how long alcohol was abused and how much alcohol was consumed during that time. In cases where the damage to the heart is severe, the chances of complete recovery are low. Once the damage is considered irreversible, it’s difficult for the heart and rest of the body to recover.

Alcohol Intake in Patients With Cardiomyopathy and Heart Failure: Consensus and Controversy

There are no specific targeted histological or immunological biomarkers for the diagnosis of alcohol-induced cardiomyopathy. The key diagnostic element is the absence of coronary artery disease.

Differences of disease progression in congestive heart failure due to alcoholic as compared to idiopathic dilated cardiomyopathy. Reported a series of 108 patients with congestive cardiomyopathy.

Coronary artery disease and atherosclerosis

Depending on the severity of cardiomyopathy, surgery might be a treatment option. Doctors may recommend open-heart surgery or even a heart transplant to replace the diseased heart. Surgically implanted devices like pacemakers, cardiac resynchronization therapy devices, left ventricular assist devices, and implantable cardioverter defibrillators, can aid in making the heart work better.

alcoholic cardiomyopathy

You may not have heard of this disease, as it isn’t as talked about as other diseases that alcoholism can cause, such as cirrhosis of the liver. However, it is very serious and can lead to life-threatening complications. Fortunately, the negative effects of alcoholic cardiomyopathy in the early stages can be reversed entirely when alcohol usage is stopped. Even in more advanced cases of alcoholic cardiomyopathy, the progression of the disease will likely stop when alcohol use is stopped.

Alcoholic Cardiomyopathy: Is it Time for Genetic Testing?∗

Those who drink alcohol excessively over time can lose the ability to successfully contract the ventricles of the heart. This weakening of heart muscles causes difficulties in pumping blood efficiently. Soon all parts of your heart—ventricles, atria—become affected by the thinning and enlargement of the heart. The Centers for Disease Control and Prevention reports that as many as one out of every 500 American adults likely suffers from cardiomyopathy.

Removal of the cobalt additive ended the epidemic in all locations. Cobalt poisoning and alcohol together acted synergistically in these patients. As the syndrome could be attributed to the toxicity of this trace element, the alcoholic cardiomyopathy additive was prohibited thereafter. LV end-diastolic dimension greater than 2 standard deviations above normal.Left ventricle ejection fraction less than 50%.Exclusion of hypertensive, valvular and ischemic heart diseases.


It is characterized by impaired ventricular dilation and contractility with normal or reduced ventricular wall thickness . Alcohol abuse is an important cause of non-ischemic cardiomyopathy, accounting for 10% cases of dilated cardiomyopathies . Extensive studies have proved the cardiotoxic effects of alcohol and its metabolite on cardiotoxicity . A lot of research has focused on the link between alcohol and heart health, with conflicting results. Some studies have shown that moderate drinking — one drink a day for women and two for men — leads to lower risks of dying from heart disease. One drink generally means a 12-ounce beer, a 6-ounce glass of wine, or a 1½-ounce shot of liquor.

  • In this type, the heart muscle becomes stiff and less flexible, so it can’t expand and fill with blood between heartbeats.
  • Those who don’t fully recover are also likely to need this kind of treatment indefinitely.
  • Overall, the annual absolute value of ASDR and age-standardized DALYs rate for males outnumbered that for females globally and in all SDI quintiles.
  • This refers to the finding in the last century that moderate alcohol consumption could be the reason for the relatively low cardiovascular disease incidence in wine-drinking regions .
  • Chronic plus binge ethanol feeding induces myocardial oxidative stress, mitochondrial and cardiovascular dysfunction, and steatosis.

However, research has shown that this almost certainly is not the case. In a study, Estruch et al found that persons who abused alcohol and had been hospitalized solely for cardiomyopathy had a higher incidence of cirrhosis than did alcohol abusers who did not have heart disease. This is believed to be due primarily to the fact that alcohol must be consumed excessively for at least 10 years to have a clinically relevant effect on the myocardium.
