Summary of studies using pharmacologic inhibition or genetic manipulation to suppress ethanol-induced changes in cardiac structure and function. In Munich, the annual consumption of beer reached 245 l per capita and year in the last quarter of the 19th century. In 1884, the pathologist and veterinarian Otto von Bollinger (Fig.  2a) described the “Munich beer heart” with fibrosis, hypertrophy, and fatty degeneration in postmortem cardiac tissue of alcoholics who consumed an estimated average of 432 liters of beer per year (Fig. 2b; [23]). At that time every 10th necropsy in men at the Munich pathology institute named cardiac dilatation and fatty degeneration as “Bierherz” being its underlying cause.

How common is this condition?

Additionally, the accepted ACM definition does not take into account a patient’s sex or body mass index (BMI). As women typically have a lower BMI than men, a similar amount of alcohol would reach a woman’s heart after consuming smaller quantities of alcohol. Data on the amount of alcohol consumption required to cause ACM are limited and controversial.

3 Relationship between independent predictors and all-cause mortality

The main histological lesions in ACM include myocyte apoptosis and necrosis causing myocytolysis and cell loss, which repair mechanisms compensate for by inducing myocyte hypertrophy and interstitial fibrosis. This limited remodeling process is regulated by cardiomyokines and growth factors (myostatin, IGF-1, FGF21, Metrnl). The final process of ACM is the result of ethanol dosage and individual predisposition and the prognosis depends on the degree of persistence in ethanol intake and the equilibrium between damage vs repair mechanisms.

  • In a subsequent study using electron microscopy, the authors found histological features that could be superimposed onto those found in hearts that had suffered hypoxia, anoxia or ischemia[43].
  • Alcohol-induced cardiomyopathy primarily affects individuals who engage in chronic, excessive, and long-term alcohol consumption.
  • In this same study, investigators found increased markers of autophagy, such as LC3B and autophagy-related gene 7 proteins and tumor necrosis factor α, along with a reduction in mTOR activity.
  • To treat the alcohol problem, a combined approach comprising pharmacologic and psychosocial therapy involving self-help groups or Alcoholics Anonymous is essential.
  • They also have not established how long a person would need to consume alcohol before developing ACM.

Laboratory findings

  • Some studies have shown that the combination of carvedilol and trimetazidine with other traditional heart failure medications is effective [1-3,7-11,16-20].
  • Finally, we analyzed and presented the synthesized literature, along with relevant findings and conclusions from the included studies, in a coherent manner.
  • Alcoholic cardiomyopathy is a leading cause of non-ischemic dilated cardiomyopathy in United States.
  • The clinical features of ACM develop when the injury is irreversible and advanced.
  • Clinical Review BoardAll Healthwise education is reviewed by a team that includes physicians, nurses, advanced practitioners, registered dieticians, and other healthcare professionals.

He hopes the process will help researchers quantify the prevalence of such language in clinical notes and identify patterns that can inform interventions. The team will also analyze the association of stigmatizing language with patient outcomes. These portable devices record your heart’s electrical activity for 24 to 48 hours or longer. They can record any irregular heart rhythms that might not be detected with traditional EKG testing.

In this section, we briefly discuss the patterns of drinking, specifically binge, as well as genetic variants in certain proteins/enzymes and variability in nutrition or dietary nutrients that may influence the occurrence of ACM. In addition, also reviewed are potential ethnic or sex difference influences. Muscular weakness may also be present because of the effect of alcohol on muscles (alcoholic myopathy). The journey to managing ACM begins with comprehensive treatment for alcohol use disorder.

Alcoholic Cardiomyopathy and Your Health

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. Regional wall motion abnormalities are not uncommon, but they are usually less prominent than those observed in persons with ischemic heart disease. In summary, there appears to be a number of ways in which mitochondrial perturbations alcoholic cardiomyopathy is especially dangerous because could contribute to both the development and progression of ACM. However, it remains to be determined whether changes in mitochondrial function are cause or consequence. Because the cardiac myocyte relative to other cell types, including the hepatocyte, contains the highest volume of mitochondria, the critical mass of mitochondria negatively impacted by ethanol before significant mitochondrial dysfunction occurs may be higher than other tissues.

Is there an immediate risk of alcohol intake?

  • “The steps we are recommending should not only help to align clinical practice with sound language guidelines, but also foster a more empathetic and supportive healthcare environment for patients,” he said.
  • Women typically have a lower BMI than men, and therefore the same alcohol exposure can be achieved with lower alcohol intake.
  • In that study, zinc supplementation suppressed some of the ethanol-induced changes in both the metallothionein knock-out mouse model and wild-type; however, ethanol-induced mitochondrial swelling and disorganization remained in both mouse groups.
  • A 2023 article notes that ACM carries a more positive outlook than ischemic cardiomyopathy, which refers to heart damage that typically occurs due to CAD.

Supportive care for withdrawal is especially important because some of its symptoms can be severe or even life-threatening. A healthcare provider can also connect you with available resources and refer you to other specialists and experts who can help you reduce or stop your alcohol intake. The available research shows that if you https://ecosoberhouse.com/ limit your alcohol intake to a certain amount, you’re less likely to develop alcohol-related health problems, including alcohol-induced cardiomyopathy. Alcohol-induced cardiomyopathy is a condition where consuming too much alcohol damages your heart. That weakens your heart muscle, keeping it from pumping as well as it should.

We identified main themes and sub-themes to provide a comprehensive overview of the current state of knowledge regarding ACM. By following this methodology, we aim to contribute to the existing body of knowledge on ACM, providing a reliable and up-to-date understanding of its pathogenesis, clinical features, diagnostic approaches, treatment options, and potential preventive strategies. Thus, although there is a certain degree of consensus regarding the recommendation of full alcohol withdrawal in ACM, it is yet to be resolved whether moderate alcohol consumption is sufficient to achieve an improvement in the prognosis of these patients. The latest two papers to be published, unlike previous papers, reported worse outcomes for ACM patients compared to DCM patients. In the first of these studies, Fauchier et al[11] studied 50 patients with ACM and 84 patients with DCM between 1986 and 1997. Although up to 81% of ACM patients received an ACEI, none received beta-blockers and the use of spironolactone was not specified, although it was probably quite low.

You may need medication adjustments, and you’ll need to stay on top of lifestyle changes, such as getting regular exercise, to effectively manage symptoms. In advanced cases of heart failure, devices like implantable cardioverter defibrillators (ICDs) or cardiac resynchronization therapy devices may be implanted to regulate heart rhythms and improve cardiac performance. On occasion and in exceptional cases, cardiac muscle biopsies may be undertaken in order to directly examine a small tissue sample from the heart for signs of cardiomyopathy.
