Alcoholic cardiomyopathy: a review

Alcohol-induced cardiomyopathy is a condition that can have major impacts on your life over time. While many people will recover from this condition if they abstain from alcohol, others will have symptoms and related problems for the rest of their life. If you are a heavy drinker, talking to a primary care provider can help keep this condition from becoming even more severe in the future, or even prevent it from happening. Your provider is the best source of information and guidance, and they can connect you to other resources that can help and experts who can assist. Alcohol-induced cardiomyopathy is a condition where consuming too much alcohol damages your heart.

In cardiomyocyte mitochondria as well as other mitochondrial types, such imbalances could lead to further decreases in cellular respiration and oxidative phosphorylation. Pathophysiologic schema for the development of alcoholic cardiomyopathy (ACM). As noted in the text, the exact amount and duration of alcohol consumption that results in ACM in human beings varies. Data from animal models and human beings with a history of long-term drinking suggest that oxidative stress may be an early and initiating mechanism. Many cellular events, such as intrinsic myocyte dysfunction, characterized by changes in calcium homeostasis and regulation and decreased myofilament sensitivity, can come about due to oxidative stress.

What is Alcoholic Cardiomyopathy

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 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 https://ecosoberhouse.com/ alcohol causing cardiomyopathy. Commonly seen cellular structural alterations include changes in the mitochondrial reticulum, cluster formation of mitochondria and disappearance of inter-mitochondrial junctions. Alcohol-related cardiomyopathy is a type of dilated cardiomyopathy, which is when your heart’s shape changes because its muscles are stretching too much.

Future studies in ACM should also address this topic, which has important economic consequences. Alterations caused by heavy alcohol intake have also been studied from the perspective of histopathology. Emmanuel Rubin analysed muscle biopsies from individuals who were previously non-drinkers and were submitted to a balanced diet with heavy alcohol intake during one month[41]. These changes, though subtle, were similar to those found by Ferrans and Hibbs in eight deceased individuals diagnosed with ACM[42,43]. On histological examination, various degrees of fibrosis, patchy areas of endocardial fibroelastosis, intramural blood clots and focal collections of swollen cells in both the epicardium and endocardium were found. Also, there were significant size variations in the myofibrils and they showed a relative decrease in the number of striations, in addition to swelling, vacuolisation and hyalinisation.

Histologic Findings

The Centers for Disease Control and Prevention (CDC) defines heavy alcohol use — also known as heavy drinking — as more than eight drinks per week for women and more than 15 drinks per week for men. One drink is equal to 14 grams of pure alcohol, which can take many different forms because some forms have a higher concentration https://ecosoberhouse.com/article/alcoholics-heart-problems-cardiomyopathy/ of alcohol than others. Another curious hypothesis from Germany suspected that some ethanol additives, such as anti-foam beer products with arsenic or cobalt content, produced cardiac toxicity and development of ACM [71]. Therefore, it is evident that ACM may develop with normal serum thiamine and electrolyte levels [38,66].

One is aware today that alcohol may cause an acute but transient vasodilation, which may lead to an initial fall in blood pressure probably mediated by the atrial natriuretic peptide (ANP) [46]. But also short- and long-term pressor effects mediated by the renin–aldosterone system and plasma vasopressin have been described [47, 48]. After myocyte apoptosis or necrosis, the heart tries to repair and regenerate this tissue damage [39,123], but the heart regenerative capacity is low as a result of the ethanol aggressive damage and develops ineffective repair mechanisms such as progressive fibrosis [124,125].

Signs and symptoms

Ethanol-induced disruption of ribosomal protein synthesis also contributes to non-contractile protein depletion [104]. Several aspects of mitochondrial function, including respiratory complex activities and mitochondrial-dependent oxidative damage and apoptosis, are also induced by ethanol [26,100]. Myocyte cytoskeletal structure [21], connexin channel communication, and desmosomal contacts are affected by ethanol, causing structural cell instability [105].

In cases where people don’t recover fully by abstaining from alcohol, most people will still see noticeable improvements in their symptoms. 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. The available research shows that if you limit your alcohol intake to a certain amount, you’re less likely to develop alcohol-related health problems, including alcohol-induced cardiomyopathy. The proportion of cardiomyopathy cases attributable to alcohol abuse has ranged from 23 to 40 percent (Piano and Phillips 2014). Recently, Guzzo-Merello and colleagues (2015) reported that, among 282 patients with a dilated cardiomyopathy phenotype, 33 percent had ACM.
