It is estimated, approximately 21-36% of all non-ischemic cardiomyopathies are attributed to alcohol. The prevalance of alcoholic cardiomyopathy in addiction units is estimated around %. Overall data with regards to alcohol induced cardiomyopathy is insuffienct and does not illustrate significant available data. They commonly include fatigue, shortness of breath, and swelling of the legs and feet.
Complications/side effects of the treatment
Alternatively, studies have analysed its effect by combining ethanol with cyanamide. However, if alcoholic cardiomyopathy is caught early and the damage isn’t severe, the condition can be treated. It’s very important to stick with the treatment plan and drug addiction treatment to stop drinking alcohol during recovery. Completely abstaining from alcohol is the key recommendation if you have alcohol-induced cardiomyopathy. Your healthcare provider will likely recommend that you also focus on improving your diet in ways that help your heart.

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. 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 Valvular Heart Disease vs Alcoholic Cardiomyopathy
This will make it easier for them to make a diagnosis and develop a treatment plan. Alcohol-induced cardiomyopathy, especially when more severe, leads to deadly problems like heart attack, stroke or heart failure. Individuals with this condition who don’t stop drinking heavily are at the greatest risk. Between 40% to 80% of people who continue to drink heavily will not survive more than 10 years after receiving this diagnosis.
- These habits can compound alcohol’s effects on the heart and increase the likelihood of developing heart disease.
- In contrast, alcoholic cardiomyopathy typically shows a globally weakened heart muscle without inflammation.
- However, ischemic heart disease often causes chest pain during physical activity or stress (angina), which is less common in alcoholic cardiomyopathy.
- In recent years, basic and clinical research has shed light on its pathogenesis, which includes direct toxic effects of alcohol on the myocardium, oxidative stress, mitochondrial dysfunction, and genetic susceptibility.
This usually involves certain types of medications that treat heart rhythm problems or other symptoms of heart failure. Those who don’t fully recover are also likely to need this kind of treatment indefinitely. In some cases, a pacemaker or other implantable device might be necessary to treat more severe heart rhythm problems.
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. Alcoholic cardiomyopathy is a serious condition that can lead to heart failure if untreated.
In contrast, beta-blockers, similar to aldosterone inhibitors, however beneficial they may be, have thus far not yielded sufficient data on their efficacy in relation to this disease. The first paper to assess the natural history and long-term prognosis of ACM was published by McDonald et al69 in 1971. He recruited 48 patients admitted to hospital with cardiomegaly without a clear aetiology and severe alcoholism. The only factor to predict a poor outcome was the duration of symptoms before admission.
The Symptoms of Alcoholic Cardiomyopathy
However, valvular heart disease often presents with a heart murmur, an https://ecosoberhouse.com/ abnormal sound heard through a stethoscope, which is not typical in alcoholic cardiomyopathy. Unexplained weight gain occurs in approximately 30-40% of patients with alcoholic cardiomyopathy. This is typically due to fluid retention rather than an increase in body fat.
Additionally, echocardiographic data suggest that subjects who do not fully withdraw from alcohol consumption, but who reduce it to moderate amounts recover LVEF in a similar manner to strict non-drinkers. Thus, Nicolás et al73 studied the evolution of the ejection fraction in 55 patients with ACM according to their degree of withdrawal. The population was divided into 3 groups according to their intake volume during the follow-up period. At the end of the first year, no differences were found among the non-drinkers, who improved by 13.1%, and among those who reduced consumption to g/d (with an average improvement of 12.2%). Conversely, those whose consumption remained in excess of 80 g/d showed an average decline of 3.8% in their ejection fraction. Although some studies have detailed structural and functional damage in proportion to the amount of alcohol consumed during a patient’s lifetime24, a large majority of authors have discarded this theory21-23,25.
Both the absence of alcoholic cardiomyopathy is especially dangerous because a direct correlation and the theory of the existence of a threshold dose (above which some alcoholics develop ACM) require the presence of individual susceptibility to alcohol induced cardiac damage63. It is unknown whether individual susceptibility would be related to increased vulnerability at the myocardial level and/or to impaired alcohol metabolism. Myocardial impairment following chronic excessive alcohol intake has been evaluated using echocardiographic and haemodynamic measurements in a significant number of reports. In these studies, haemodynamic and echocardiographic parameters were measured in individuals starting an alcohol withdrawal program.
