Animals received different concentrations of ethanol in their drinking water (10%, 14%, 18% v/v) for variable weeks (12, 8, and 4, respectively). In all three ethanol groups, compared to control groups there was a significant increase in heart weight-to-body weight ratios. In terms of cardiac function and structure, significant decreases in fractional shortening and ejection fraction were found in all ethanol groups, but no other changes were found in other echocardiography-derived parameters between the alcohol alcoholic cardiomyopathy is especially dangerous because and control groups. Intra-myocardial lipid accumulation, which was direct contact with the mitochondria, was found in all ethanol-fed groups and was significantly correlated with increased myocardial triglyceride content. LCFA uptake was evaluated in isolated cardiomyocytes obtained from ethanol-fed rats and was increased in a dose-dependent manner (i.e., greatest in 18% ethanol group) (33). Among the LCFA transport genes examined in all ethanol groups, increases were found in Cd36 and Scd-1 expression.

1. The Natural Course of ACM

  • This was questioned by other authors, who pointed out that these conclusions could not be drawn, as alcohol itself also induces changes in the pre-load and after-load conditions, which influence cardiac contractility[35].
  • Other ethanol-induced changes may be related to enzymes that modulate protein synthesis and/or breakdown (e.g., ubiquitine-ligases).
  • Daily alcohol consumption of 80 g per day or more for more than 5 years significantly increases the risk, however not all chronic alcohol users will develop Alcohol-induced cardiomyopathy.
  • The beneficial heart wine as universal remedy in medieval ages by Hildegard von Bingen [11] found its later correlates in many observations at the beginning of modern medicine when coronary artery disease (CAD) and its risk factors and symptoms received more attention.
  • The relationship of alcohol with heart disease or dementia is complicated by the fact that moderate alcohol consumption was shown not only to be detrimental but to a certain degree also protective against cardiovascular disease [14] or to cognitive function in predementia.

Low-to-moderate alcohol use may mitigate certain mechanisms such as risk and hemostatic factors affecting atherosclerosis and inflammation, pathophysiologic processes integral to most CV disease. Both the negative and positive effects of alcohol use on particular CV conditions are presented here. The review concludes by suggesting several promising avenues for future research related to alcohol use and CV disease.

  • New strategies are addressed to decrease myocyte hypertrophy and interstitial fibrosis and try to improve myocyte regeneration, minimizing ethanol-related cardiac damage.
  • The source was identified to be the filter of choice for wine and beer, i.e., diatomaceous earth [36].
  • Alcohol use was protective against CHD for subjects in most countries, except for people of South Asian ethnicity living in South Asia (India, Bangladesh, Nepal, Pakistan, and Sri Lanka).
  • Decreases in mTOR activation may play a role in reduced myocardial protein synthesis, ventricular wall thinning, and dilation.
  • According to recent data, a genetic form of DCM could be present in up to 50% of idiopathic DCM cases, and other specific forms of DCM such as peripartum cardiomyopathy have been shown to have a genetic basis in a significant number of cases[68].
  • 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].
  • Absorption levels of Indium-111 were high in 75% of patients who continued drinking and in only 32% of those who had withdrawn from consuming alcohol.


At the experimental level, some gender differences also are evident in functional proteomic analysis, with sex-dependent differences in structural and energy-producing myocardial proteins in a rat model of alcoholic cardiomyopathy [96]. The biological reason for this gender difference is based on different ethanol absorption rates, distribution pattern, and metabolism in women compared to men [52]. Therefore, efforts to prevent ACM development in women should be specifically addressed [97]. During pregnancy, ethanol consumption should be clearly discouraged because of the possibility of fetal alcohol syndrome or the development of other congenital heart diseases [97]. Patients with alcoholic cardiomyopathy, therefore, usually present with symptoms of heart failure, i. Echocardiography may reveal a mild or severe depression of cardiac function and ejection fraction or even show hypertrophy in the beginning [109].


High levels of triglycerides in the blood have therefore been linked to atherosclerosis, heart disease, and stroke. Among these is the activation of mitogen-activated protein kinases (MAPK) signaling cascades. There also is desensitization of the mitochondrial permeability transition pore, which can mitigate ischemia–reperfusion injury (Walker et al. 2013). In addition, alcohol may attenuate ischemia–reperfusion injury by activating protein kinase C epsilon (PKCɛ) (Walker et al. 2013). Activation of PKCɛ may protect the myocardium against ischemia–reperfusion injury by stimulating the opening of mitochondrial ATP-sensitive potassium channels. This in turn prevents the opening of the mitochondrial permeability transition pore (Walker et al. 2013).
