The alcohol-induced cardiomyopathy: A cardiovascular magnetic resonance characterization

S3 gallop sound along with apical pansystolic murmur due to mitral regurgitation is often heard. 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. Often, when a doctor suspects cardiomyopathy, they will order an echocardiogram. This test will assess the ejection fraction (EF), a measurement that expresses how much blood the LV pumps out with each contraction. Once doctors have found this, they will look for the cause of the weakened heart.

Hemostatic Factors

In that study, the daily co-administration of vitamin E (10 mg/kg) or another antioxidant, cyanidanol-3 (300 mg/kg), prevented these changes (40). The pathologic and histologic findings of alcoholic cardiomyopathy is especially dangerous because (AC) are essentially indistinguishable from those of other forms of dilated cardiomyopathy (DC). Findings from gross examination include an enlarged heart with 4-chamber dilatation and overall increased cardiac mass. Histologically, light microscopy reveals interstitial fibrosis (a finding that has been shown to be prevented by zinc supplementation in the mouse model), myocyte necrosis with hypertrophy of other myocytes, and evidence of inflammation. Electron microscopy reveals mitochondrial enlargement and disorganization, dilatation of the sarcoplasmic reticulum, fat and glycogen deposition, and dilatation of the intercalating discs. Hypertension due to alcohol may be a confounding comorbidity in that it may contribute to LV dysfunction; therefore, LV dysfunction due to hypertension must be differentiated from pure AC.

  • Finally, it is worth stressing that a large majority of studies on the physiopathology and prognosis of ACM were conducted some years ago, prior to the development of our current understanding regarding the role of genetics in DCM[67].
  • To diagnose this condition, healthcare providers will typically use several of the following methods.
  • Acute or chronic right heart failure leads to elevation of liver enzymes most likely due to liver congestion, whereas  cirrhosis due to cardiac disease is infrequent.
  • Alcoholic cardiomyopathy affects the heart’s ability to pump oxygen-rich blood around the body.

For many decades, ACM has been considered one of the main causes of left ventricular dysfunction in developed countries. Specifically in the United States, ACM was declared the leading cause of non-ischemic DCM[7]; a fact related to the high consumption of alcoholic beverages worldwide, which is particularly elevated in Western countries[26] . Unfortunately Lazarević et al[23], as in most of these studies, systematically excluded patients with a history of heart disease or with HF symptoms. It is therefore possible that most of these studies may have also consistently omitted most alcohol abusers in whom alcohol had already caused significant ventricular dysfunction.

How is this condition treated, and can it be cured?

Regional wall motion abnormalities are not uncommon, but they are usually less prominent than those observed in persons with ischemic heart disease. Despite the key clinical importance of alcohol as a cause of DCM, relatively few studies have investigated the effects of alcohol on the heart and the clinical characteristics of DCM caused by excessive alcohol consumption (known as https://ecosoberhouse.com/). Evidence of oxidative stress is found after short periods of alcohol consumption (2 to 18 weeks), at least in animal models.

  • Let your healthcare professional know if you have a family history of the condition.
  • Altered platelet responses (e.g., increased platelet activation/aggregation) leads to blood-clot formation (or thrombosis) in certain CV conditions.

The researchers found that the alcohol-drinking subjects (particularly those who were insulin sensitive) had higher insulin levels and a slower rise in glucose levels after a low-carb meal. They recommended confirming these results in younger women and in men, particularly since their subjects had been older women, who have more significant cardiovascular risk. For example, alcohol consumption typically has been measured through self-report.

Frequently, a relative decrease occurs in systolic blood pressure because of reduced cardiac output and increased diastolic blood pressure due to peripheral vasoconstriction, resulting in a decrease in the pulse pressure. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), AUD is a brain disorder that doctors characterize by the inability to stop or control alcohol consumption. This inability occurs despite adverse effects on the person’s health, occupation, or relationships. ACM is a type of heart disease that develops due to chronic alcohol consumption. One of the few papers analysing genetic susceptibility in ACM was published by Fernández-Solà et al[64] in 2002.

Finally, it is worth stressing that a large majority of studies on the physiopathology and prognosis of ACM were conducted some years ago, prior to the development of our current understanding regarding the role of genetics in DCM[67]. 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]. It is therefore possible that patients with ACM could also harbour a genetic substrate that predisposes them to this form of cardiomyopathy. In this respect, a higher prevalence of excessive alcohol consumption has been reported among individuals diagnosed with DCM than in the general population[8]. Epidemiological studies analysing the relationship between excessive alcohol consumption and the development of DCM have found the existence of a reciprocal link between both disorders.

Derangements in Fatty Acid Metabolism and Transport

In addition, people who receive early treatment for ACM, including medication and lifestyle modifications, have a better chance of improving their heart function and overall health. Studies of alcohol and stroke are complicated by the various contributing factors to stroke. Heavier drinkers are apparently at a higher risk of hemorrhagic stroke, whereas moderate drinking might be neutral or even result in a reduced risk of ischemic stroke. In the Caerphilly prospective heart disease study, platelet aggregation induced by adenosine diphosphate was also inhibited in subjects who drank alcohol [99].
