The Effects of Ethanol on the Heart: Alcoholic Cardiomyopathy

what is alcoholic cardiomyopathy

These include damaging factors such as acetaldehyde or ROS, cardiac fibrosis, or apoptosis. Furthermore, alcohol consumption has also been classified in the literature by ranges of consumption as mild, moderate, and heavy drinking.11 In this regard, these categories have the following consumption thresholds that also differ according to sex. In the course of ethanol-induced cardiac damage, one of the more relevant findings is that ethanol exerts its deleterious effects on cardiac myocytes at multiples sites (membrane, receptors, mitochondria, ribosomes, sarcolemma, DNA, or cytoskeleton) 18,19,98 (Table 1). 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. However, there is a clear personal susceptibility of this effect that creates a wide variability range and supposes significant inter-individual differences 50,66.

What is Alcoholic Cardiomyopathy?

Since myocardium requires a high energy supply to maintain persistent sarcomere contractions, it was supposed that alcohol could exert its damaging effect on the mitochondrial energy supply system, with the disruption of what is alcoholic cardiomyopathy oxidative control mechanisms 26,100. In fact, mitochondrial structural changes have been described in chronic alcohol consumers, with swollen megamitochondria and the distortion of inner cristae 107,108. Functionally high ethanol produces disruptions in the myocyte oxidative pattern and decreases in Complex I, II, and IV of the mitochondrial respiratory chain 100,109,110. As a reflection of this metabolic derangement, cytoplasmic lipid droplets and glycogen deposits appear. It has been said that ethanol is the “perfect drug” because of its pleasant effects but damaging long-term effect 1,6.

Is there an immediate risk of alcohol intake?

Chronic ethanol misuse clearly depresses protein synthesis and degradation, involving both structural and non-structural heart proteins 104,128. At a pathological level, sarcomere Z-line distortion and disruption of the sarcomere pattern Substance abuse leads to myocytolysis 107,129. Myocytolysis is evident through focal myofiber dissolution, cell vacuolization, and fiber disarray 19 (Figure 2). The sarcomere complex is early affected by ethanol, decreasing the titin content, a protein that is responsible for sarcomere relaxation and LV distensibility 130. This damage first induces diastolic dysfunction, which is initially subclinical and later clinically apparent 57. In addition, contractile sarcomere proteins such as Myosin, Actin, and Troponin are also affected by ethanol, causing the functional progressive depression of myocyte contractility, inducing progression to heart failure 56,104,131.

How can a Peripartum cardiomyopathy be diagnosed and what are treatment options?

The source was identified to be the filter of choice for wine and beer, i.e., diatomaceous earth 36. The German word for it is Kieselguhr, a beige powder made up of the skeletons of diatoms. The trace amounts of arsenic have not been comparable to the arsenic-in-beer endemic in Manchester but may still reach up to 10-times the amount admitted for arsenic in drinking water in the European Union and the US.

  • For example, the NIH reports that arrhythmogenic cardiomyopathy—caused by gene mutations—usually affects teens or young adults and is the most common cause of sudden death in young people and in athletes.
  • While some consider that this toxin alone is able to cause such a disease18,19, others contend that it is just a trigger or an agent favouring DCM3,21,22.
  • Variations in genes related to alcohol metabolism and cardiac function can influence the risk.
  • Research is ongoing to understand the genetic factors contributing to alcoholic cardiomyopathy.
  • However, if alcoholic cardiomyopathy is caught early and the damage isn’t severe, the condition can be treated.

This is typically reserved for patients who have not responded to other treatments and have a significantly reduced quality of life. Chronic alcoholics often suffer from nutritional deficiencies, particularly in essential vitamins and minerals like thiamine (Vitamin B1), which are crucial for heart health. In the 1989 study by Urbano-Marquez et al, a comparison of symptomatic to asymptomatic patients revealed more extensive fibrosis in patients with symptoms. 8 Other investigators have looked at immunohistologic markers and have suggested that the presence of these markers might suggest an inflammatory process such as myocarditis and that their absence may point more toward AC or an idiopathic etiology. Electrocardiographic findings https://ecosoberhouse.com/ are frequently abnormal, and these findings may be the only indication of heart disease in asymptomatic patients. Patients can expect a gradual reduction in cholesterol levels, which may help slow heart disease progression.

Markers such as ethyl sulphate, phosphatidyl ethanol, and fatty acid ethyl esters are not routinely done. As early as in 1915, Lian 45 reported in middle-aged French servicemen during the first world war that heavy drinking could lead to hypertension. It took almost 60 years before further attention was paid to the complex interaction between the heart and the peripheral vasculature in various cross-sectional and prospective epidemiologic studies, which have empirically confirmed this early report. 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. More than 1.8 million individuals in Germany with a total population of 81 million inhabitants are alcohol dependant.

What are differences between ischemic and dilated cardiomyopathy?

Most common age population for ACM is males from age with significant history of alcohol use for more than 10 years. Females constitute roughly 14 % of cases of alcohol induced cardiomyopathy however lifetime exposure required for women to develop alcohol induced cardiomyopathy is less compared to men. Abnormal heart sounds, murmurs, ECG abnormalities, and enlarged heart on chest x-ray may lead to the diagnosis. It’s important to be honest with your doctor about the extent of your alcohol use, including the number and amount of drinks you have each day. This will make it easier for them to make a diagnosis and develop a treatment plan. It’s important to note that alcoholic cardiomyopathy may not cause any symptoms until the disease is more advanced.
