Alcohol Intake in Patients With Cardiomyopathy and Heart Failure: Consensus and Controversy Circulation: Heart Failure

Aucune note

It is at this stage – when trying to quit – that many binge drinkers and chronic drinkers find that they cannot quit, or can’t stay sober for an extended period of time without relapsing. Alcoholic Cardiomyopathy is the most serious concerns of the effects of alcohol on the heart. Cardiomyopathy means “heart failure,” and alcoholic cardiomyopathy simply means that the heart failure is caused by alcohol. Alcoholic cardiomyopathy is a progressive disease, meaning that it worsens over time – especially with continued alcohol use. In the Caerphilly prospective heart disease study, platelet aggregation induced by adenosine diphosphate was also inhibited in subjects who drank alcohol . Assessing differences between various forms of alcoholic beverages it should be noted that resveratrol leads in vitro to platelet inhibition in a dose-dependent manner and has shown effects on all-cause mortality in a community-based study .

This imaging test uses computer processing to assemble X-ray images into a 3-D picture of the heart. Dilated cardiomyopathy makes your heart change in very specific ways, and doctors — especially cardiologists have training that helps them spot these changes. Though they aren’t causes of alcohol-induced cardiomyopathy, other lifestyle choices can make it worse.

The global ACM burden in both sexes and different age groups in 2019. ACM – alcoholic cardiomyopathy, DALY – disability-adjusted life year. Disability-adjusted life years equal the sum of years of life lost and years lived with disability .

Palpitations and syncopal episodes can occur due to tachyarrhythmias seen in alcoholic cardiomyopathy. Drinking habits and echocardiogram evaluation were studied in in 2368 adults in a long follow up. Increased alcohol intake had a direct inverse adverse association with ventricular structure. Increase alcohol consumption had greater indexed left ventricular mass and increased left ventricular end-diastolic volume after 20 years. Alcohol consumption did not show any association with systolic dysfunction. Alcohol-induced toxicity leads to non-ischemic dilated cardiomyopathy characterized by loss of contractile function and dilatation of myocardial ventricles. These findings are coupled with a clinical history of heavy alcohol use in the absence of coronary artery disease as a supportive etiology.

Do the Above Results Suggest it Is Time for Genetic Testing in ACM?

Initially a clinically silent condition that can be detected by echocardiographic and electrocardiographic abnormalities, alcoholic cardiomyopathy slowly progresses to overt low-output heart failure. Abstinence is beneficial and can determine the reversal of cardiac impairment with a positive impact on prognosis. Specific diagnostic criteria are not yet available and differentiating alcoholic cardiomyopathy from other forms of cardiovascular dysfunction such as cirrhotic cardiomyopathy is challenging. In our study population, subjects with moderate alcohol consumption showed similar Kmono values to healthy controls, but this measurement was significantly reduced in those with heavy alcohol consumption. It has been shown that alcohol can inhibit mitochondrial respiration and the activity of enzymes in the tricarboxylic acid cycle, and interfere with both mitochondrial calcium uptake and binding synchronously . The reduction of Kmono may therefore represent the inhibition of myocardial energy metabolism due to chronic alcohol consumption.

Treatment for alcoholic cardiomyopathy is directed towards source control. Many changes can be observed including premature atrial or ventricular contractions, supraventricular tachycardias, atrioventricular blocks, bundle branch blocks, QT prolongation, non-specific ST and T wave changes and abnormal Q waves. You should also follow your doctor’s guidance and advice on any treatments you receive. This includes taking your medication as instructed and eating a healthy diet. If you have any questions about how to do either of these, your healthcare provider can answer them and offer you help and resources along the way.

This activity highlights the role of the interprofessional team in caring for patients with this condition. Is a severe consequence of chronic alcohol abuse and is a form of dilated cardiomyopathy. Current research into the pathogenesis of this condition has refined our understanding of the direct and indirect toxic effects of alcohol on the heart. Epidemiological studies attribute a significant role to alcohol abuse as a cardiovascular risk factor while clinical reports have established that alcoholic cardiomyopathy results in increased morbidity and mortality.

In a world-wide setting, alcohol use disorders show similarities in developed countries, where alcohol is cheap and readily available . The many complications of alcohol use and abuse are both mental and physical—in particular, gastrointestinal , neurological , and cardiological . A lot of research has focused on the link between alcohol and heart health, with conflicting results. Some studies have shown that moderate drinking — one drink a day for women and two for men — leads to lower risks of dying from heart disease. One drink generally means a 12-ounce beer, a 6-ounce glass of wine, or a 1½-ounce shot of liquor. Alcoholic cardiomyopathy is caused by long-term heavy alcohol use.

Gender Differences in Alcohol Pathology

Use of ethanol alone or ethanol with an alcohol dehydrogenase inhibitor resulted in a 25% decrease in protein synthesis. When the rats were given an inhibitor of acetaldehyde dehydrogenase to increase levels of the ethanol metabolite acetaldehyde, an 80% decrease in protein synthesis occurred. Based on these data, acute ethanol-induced injury appears to be mediated by ethanol and acetaldehyde; the latter may play a more important role. When symptoms do occur, they’re often those of heart failure. They commonly include fatigue, shortness of breath, and swelling of the legs and feet.
