The key to diagnosis is a personal history of chronic heavy alcohol use and the absence of other etiologies. Certain microscopic features may suggest damage secondary to alcohol causing cardiomyopathy. Commonly seen cellular structural alterations include changes in the mitochondrial reticulum, cluster formation of mitochondria and disappearance of inter-mitochondrial junctions. Patients can expect a gradual reduction in cholesterol levels, which may help slow heart disease progression. The consequences of advanced cases of ACM are unlikely to reverse with treatment but may be managed with some standard treatments for heart failure. Not everyone who uses alcohol develops serious heart problems like ACM, but when someone does, it can be very serious.
- Ethyl alcohol, also known as “ethanol” or usually just as “alcohol”, is the most consumed drug in human history 1.
- Along with signs of heart failure such as increased N-terminal pro-B-type natriuretic peptide, blood tests can provide hints suggesting chronic alcohol abuse.
- Alcohol can have a toxic effect on many of your organs, such as the liver and heart.

Depression of LV ejection fraction (EF) is the hallmark of this period that also occurs with a reduction in LV shortening fraction, increase in LV diameter, and mass indices that may be measured by echocardiography or cardiac MR spectroscopy 40,52. Congestive symptoms, such as the expression of right ventricular failure, with peripheral edema or anasarca, are characteristic of advanced cases of ACM 42,56. Despite the key clinical importance of alcohol as a cause of DCM, relatively few studies have investigated the alcoholic cardiomyopathy is especially dangerous because effects of alcohol on the heart and the clinical characteristics of DCM caused by excessive alcohol consumption (known as alcoholic cardiomyopathy). Recently, apoptosis and necrosis have been also attributed to autophagy in ACM 18. In order to maintain cardiac homeostasis, the removal of defective organelles and cell debris by autophagy is essential both in physiological and pathological conditions 115. Dysregulated excessive autophagy, together with other factors such as oxidative stress, neurohormonal activation, and altered fatty acid metabolism, contributes to cardiac structural and functional damage following alcoholism.
Irregular Heartbeat (Arrhythmia)
Markers such as ethyl sulphate, phosphatidyl ethanol, and fatty acid ethyl esters are not routinely done. In all ACM studies, inclusion of patients is based on patients’ self-reported alcohol drinking habits, which may lead to an underestimation of the prevalence of ACM together with problematic identification of patients who abstain and those who continue drinking. Furthermore, in many of these reports, comorbid conditions, especially myocarditis and other addictions such as cocaine and nicotine, were not reported. Ballester specifically analysed the effects of alcohol withdrawal on the myocardium using antimyosin antibodies labelled with Indium-11172. This radiotracer has been acknowledged as an indicator of irreversible myocardial damage. Of the 56 patients included in the study, 28 were former drinkers and 28 continued consuming alcohol during the study.
How to Know if You Might Have Hypertensive Heart Disease vs Alcoholic Cardiomyopathy
The ryanodine L-type Ca2+ receptor at the sarcoplasmic reticulum (SR) is also significantly affected by ethanol in a dose-dependent manner 86,102. This causes a decrease in sarcolemmal contraction and also disturbance in other intercellular organelles dependent of i.c. As an adaptive process, chronic alcohol consumption induces up-regulation of myocardial L-type Ca 2+ channel receptors, whose activity decreases in the presence of cardiomyopathy 103. In fact, the particular effects that ethanol produces in a specific organ depend on several factors 18,19. One is the physical characteristics of ethanol itself, with a low molecular size, high distribution capacity, and high tissue reactivity. In addition, there is a relevant role on each organ, particularly on defense and adaptive mechanisms, with a clear induction of anti-oxidant, metabolic, and anti-inflammatory protective responses as a result of ethanol aggression 18,25,26.
Alcoholic cardiomyopathy is diagnosed when the heart muscle and surrounding blood vessels stop functioning correctly. 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. However, cardiac https://ecosoberhouse.com/ apoptosis may also develop independently of the mitochondrial pathway 115 through the extrinsic pathway, which involves cell surface death receptors 116. In addition to inducing apoptosis, ethanol inhibits the effect of anti-apoptotic molecules such as BCL-2 101.
- Commonly seen cellular structural alterations include changes in the mitochondrial reticulum, cluster formation of mitochondria and disappearance of inter-mitochondrial junctions.
- Data suggests patients with successful quitting of alcohol have improved overall outcomes with a reduced number of inpatient admissions and improvement in diameter size on echocardiogram.
- These changes, though subtle, were similar to those found by Ferrans and Hibbs in eight deceased individuals diagnosed with ACM42,43.
- The signs and symptoms of alcoholic cardiomyopathy (ACM) can vary depending on the severity of the condition.6 In the early stages, people with ACM may not experience any symptoms.
Alcoholic Cardiomyopathy Treatment
- Until the second part of the 20th century, there was no scientific evidence on the direct and dose-dependent effect of ethanol on the heart as cause of ACM 6,38.
- In all ACM studies, inclusion of patients is based on patients’ self-reported alcohol drinking habits, which may lead to an underestimation of the prevalence of ACM together with problematic identification of patients who abstain and those who continue drinking.
- One of the most relevant targets of ethanol in the membrane is the disruption of membrane receptor composition and activities 86.
- In addition to inducing apoptosis, ethanol inhibits the effect of anti-apoptotic molecules such as BCL-2 101.
- Virtual consultations allow you to receive personalized care, discuss symptoms, and adjust treatments without in-person visits, especially beneficial for those with mobility issues or living in remote areas.
- Alcoholic cardiomyopathy (ACM) is a disease in which the long-term consumption of alcohol leads to heart failure.1 ACM is a type of dilated cardiomyopathy.
This article will discuss the risk factors, symptoms, diagnostic tests, medications, procedures, and lifestyle changes that can help manage the condition. Alcohol-induced cardiomyopathy remains a relevant health problem, for which the mainstay of treatment is alcohol abstinence. 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.
Direct toxic effect of ethanol
Consumption of other drugs such as cocaine or tobacco may interact with ethanol and potentiate the final ethanol-related cardiac damage 22,72. In patients exhibiting chronic alcohol use, other causes of dilated cardiomyopathy need workup. Investigative work up such as mean corpuscular volume (MCV), gamma-glutamyl-transpeptidase (GGT), elevated transaminases (AST, ALT) and elevated INR usually are seen in liver injury can be helpful as supportive evidence of alcohol use.1415. 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 alcoholism symptoms and well-being within a few weeks.
