Although the severity of histological alterations on endomyocardial biopsy correlates with the degree of heart failure in one of our studies, biopsy is not in common use for prognostic purposes 117. Even the recovery after abstinence of alcohol is hard to predict based on morphometric evaluation of endomyocardial biopsies 118. 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. One is aware alcoholic cardiomyopathy symptoms 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.

To identify the causative agent of AC, investigators administered ethanol to rats pretreated with inhibitors of ethanol metabolism. 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.
How to Know if You Might Have Heart Failure vs Alcoholic Cardiomyopathy
Prognosis in individuals with low or moderate consumption up to one or two drinks per day in men and one drink in women is not different from people who do not drink at all. In CAD, diabetes, and stroke prevention the J‑type mortality curves even indicate some benefit apart from the social ”well-being“. In patients with chronic alcohol use disorders and severe heart failure prognosis is poor, since continued alcohol abuse results in refractory congestive heart failure. Death might also be sudden due to arrhythmias, heart conduction block, and systemic or pulmonary embolism. This was an excellent result long before ACE inhibitors or betablockers were available for heart failure treatment 57.
Clinical manifestations and diagnosis of alcohol-induced cardiomyopathy
- Alcoholic cardiomyopathy (ACM) is a type of heart disease that can result from chronic alcohol consumption.
- Moreover, there is a decrease in the left ventricular mass index and ejection fraction, falling below the normal range.
- It is therefore possible that patients with ACM could also harbour a genetic substrate that predisposes them to this form of cardiomyopathy.
This heart dysfunction causes faints, shortness of breath, fluid retention, and overall decreased quality of life. Read on to learn about alcohol-induced cardiomyopathy diagnosis, treatment and prevention. To avoid alcoholic cardiomyopathy, abstain from alcohol or drink in moderation. Because alcoholic cardiomyopathy is influenced by how much alcohol you drink, lessening your alcohol intake can reduce the likelihood of developing the condition. By being more susceptible to the damaging effects of alcohol, you’re more likely to develop alcoholic cardiomyopathy.
It is crucial to recognize that excessive alcohol consumption can lead to alcohol-induced cardiotoxicity, characterized by acute and chronic effects on the heart. Mechanisms such as mitochondria damage, oxidative stress injury, and alteration of calcium homeostasis contribute to the pathogenesis of alcoholic cardiomyopathy. Therefore, moderation and responsible alcohol consumption play a pivotal role in protecting cardiac health and reducing the risk of developing this serious condition.
Others who are beginning to struggle with breathlessness or chest pain may need to make some lifestyle changes or take medications. Sarcomere gene mutations are the primary genetic cause of hypertrophic cardiomyopathy. Normally, sarcomere genes work to encode proteins that are responsible for helping the heart muscle contract and relax properly. An intervention typically ends with family members arguing with both the alcoholic cardiomyopathy to admit their illness and seek help right away. The patient may become violent, angry, angry, angry, unhappy, uncommunicative, and otherwise adversely affected by an action.
Alcoholic cardiomyopathy is a serious heart condition caused by long-term, excessive alcohol consumption. It weakens the heart muscle, making it harder for the heart to pump blood effectively. Over time, this can lead to heart failure and other life-threatening complications. Recognized as a significant health issue, particularly in individuals with chronic alcohol use, alcoholic cardiomyopathy has been a concern for decades. This article provides a clear and compassionate overview of alcoholic cardiomyopathy, covering its risk factors, symptoms, diagnostic tests, treatments, and lifestyle changes that can help manage the condition. By understanding this condition better, patients can take steps to improve their heart health and overall well-being.
- This inefficient pumping of blood can impact all your body’s vital functions and lead to life-threatening heart issues.
- The heart muscle, once structurally altered, remains vulnerable to subsequent insults.
- When this happens, the symptoms often become similar to those of heart disease.
- Very often your physician will ask you questions regarding your alcohol consumption history to ascertain the level of alcohol abuse.
- Not everyone who binge drinks has an AUD, but they are at higher risk for getting one.
Specifically, among alcoholics they found a prevalence of DCM of 0.43% in women and 0.25% in men, whereas the described prevalence of DCM in the general population is 0.03% to 0.05%18,19. Recovery is highly individualized and may or may not include medication-assisted treatment (MAT). Amy Scanlon, MD, FACC, is a practicing private practice cardiologist at Consultants in Cardiology and the current team cardiologist for Seton Hall University. Dr. Scanlon has authored several published articles including the American College of Cardiology’s Preparticipation Cardiovascular Screening for Adolescent alcohol rehab and Young Adult Athletes module.

Several pathophysiological mechanisms have been proposed at the basis of alcohol-induced damage, most of which are still object of research. Unfortunately, symptoms of alcoholic cardiomyopathy are not specific and common to other forms of heart failure and appear when dilatation and systolic dysfunction are consolidated. Thus, early diagnosis is mandatory to prevent the development and progression to heart failure. Although physicians are aware of this disease, several pitfalls in the diagnosis, natural history, prognosis and treatment are still present. The aim of this narrative review is to describe clinical characteristics of alcoholic cardiomyopathy, highlighting the areas of uncertainty.
