Recently, Hu et al. found decreased myocardial ATP content levels along with decreased myocardial contractility (e.g., decreased ejection fraction and factional shortening) in mice receiving ethanol (18% v\/v ethanol in drinking water) for 4 weeks (33). Although speculative, this reduction in ATP synthesis may be just enough to depress intracellular functions such as sarcoplasmic reticulum uptake of calcium, myofibrillar ATPase activity, and changes in cross-bridge cycling. Oxidative phosphorylation is a key element of mitochondrial bioenergetics and reflects the mechanisms of energy transduction and respiratory control in the electron transport system.<\/p>\n

Therefore, because of its multiple actions, acetaldehyde may influence ACM pathogenesis in addition to ethanol effect itself 20,76,77. Occidental Berberi is the term used for the clinical scenario caused by thiamine deficit, a situation commonly present in chronic alcohol misuse, and was attributed as the cause of ACM 68,69. Similarly, electrolyte (Na, K, Ca, Mg, P) deficiencies or disturbances may play a major role in cardiac function, and ethanol misuse may be related to them 52. Selenium deficit (Keshan disease in China) could also induce ACM in specific areas 70. This ethanol misuse at high consumption rates causes a variety of health problems, ethanol being the sixth most relevant factor of global burden of disease and responsible for 5.3% of all deaths 5. Despite this clear epidemiological evidence of ethanol\u2019s unsafe consumption and increased health risk, results of consumption policies are not effective enough.<\/p>\n

6. The Effect of Low-dose Ethanol on ACM<\/h2>\n

• A repeat echocardiogram revealed normal left ventricular function, with an ejection fraction of 62% by modified Simpson\u2019s biplane method.<\/li>\n
• Basic research studies have described an abundance of mechanisms that could underscore the functional and structural alterations found in ACM.<\/li>\n
• But also short- and long-term pressor effects mediated by the renin\u2013aldosterone system and plasma vasopressin have been described 47, 48.<\/li>\n
• Furthermore, it is now evident that mitochondria function in networks and that when mitochondria become damaged their function can possibly restored by fusion with neighboring mitochondria (55).<\/li>\n
• Measuring blood alcohol concentration in an acute intoxication gives baseline information but does not permit deductions to chronic misuse.<\/li>\n<\/ul>\n

  In his 1906 textbook The Study of the Pulse, William MacKenzie described cases of heart failure attributed to alcohol and first used the term \u201calcoholic heart disease\u201d 26. 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 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.<\/p>\n

  • Because of this, their origin could be multifactorial and linked both to the alcohol molecule and to its main metabolite, acetaldehyde.<\/li>\n
  • The findings suggest a protective effect of overexpression of IGF-1 in the transgenic animals (Zhang et al. 2014).<\/li>\n
  • Additionally, the accepted ACM definition does not take into account a patient\u2019s sex or body mass index (BMI).<\/li>\n
  • For example, certain levels of alcohol consumption that lower risk for CHD may increase it for other CV conditions, such as stroke.<\/li>\n
  • Thiamine (200 mg once daily), multivitamins, vitamin B-12, folate, and mineral supplementation are beneficial for patients with AC because of the significant prevalence of concomitant nutritional or electrolyte deficiencies in these patients.<\/li>\n
  • Some adverse BP-related mechanisms that may be triggered by alcohol include changes in intracellular calcium levels, baroreflex control, and heart rate and activation of other neurohormonal systems besides the RAAS, such as the sympathetic nervous system (Marchi et al. 2014).<\/li>\n
  • The association between alcohol-induced cardiomyopathy and myocarditis is controversial.<\/li>\n<\/ul>\n
