Alcohol-Induced Cardiomyopathy: Causes, Symptoms and Treatment

Virtual consultations allow you to receive personalized care, discuss symptoms, and adjust treatments without in-person visits, especially beneficial for those with mobility issues or living in remote areas. Patients may notice improved heart function and reduced swelling within a few weeks, though regular blood tests are required to monitor potassium levels and kidney function. To our knowledge, our study determined prognostic factors for ACM outcome in the largest cohort of ACM patients described to date. Our data show that the variables most closely predicting a poor outcome in ACM are QRS duration, SBP and NYHA classification at admission.
How should I change my diet if I have this condition?
- To diagnose this condition, healthcare providers will typically use several of the following methods.
- However, dilated cardiomyopathy can occur without heavy alcohol use, while alcoholic cardiomyopathy is directly linked to chronic alcohol consumption.
- This disruption partly explains why heavy drinkers experience more frequent fractures and slower healing.
- The liver plays a critical role in producing immune-related proteins and removing toxins from the body.
However, this is usually not an option because there are so few hearts available from organ donors. For that reason, transplant programs have very strict list requirements to qualify for a transplant and abstaining from alcohol is almost always on those lists. Electrolyte abnormalities, including hypokalemia, https://ecosoberhouse.com/ hypomagnesemia, and hypophosphatemia, should be corrected promptly because of the risk of arrhythmia and sudden death.

- Other lifestyle changes a person will likely need to make include reducing the amount of fluid they drink or salt they eat.
- Ten patients who continued to drink higher amounts of alcohol all died during the follow-up period.
- These conditions can manifest as difficulties with learning new information, impaired decision-making, and reduced problem-solving abilities.
- Alcohol-induced hypertension creates additional kidney strain, as these organs experience the full force of elevated blood pressure.
New therapeutic strategies for AC are being developed with the support of animal models. As the pathogenesis of AC is complex, specific treatments focus on different targets. These include damaging factors such as acetaldehyde or ROS, cardiac fibrosis, or apoptosis. Genetic, psychological, social and environmental factors can impact how drinking alcohol affects your body and behavior. Theories suggest that for certain people drinking has a different and stronger impact that can lead to alcohol use disorder.
Histologic Findings
In fact, it contributes to about 178,000 deaths annually in the U.S., making alcohol one of the leading preventable causes of death in the United States. Beyond dehydration effects, alcohol and its breakdown products directly damage sensitive kidney structures, particularly with regular heavy consumption. The proximal tubules, responsible for reabsorbing nutrients from filtered blood, show particular vulnerability to this toxic exposure.
Alcoholic Cardiomyopathy and Your Health
One of the few papers analysing genetic susceptibility in ACM was published by Fernández-Solà et al64 in 2002. He compared the prevalence of different polymorphisms of the angiotensin-converting enzyme gene in 30 ACM patients and in 27 alcoholics with normal ventricular function. Furthermore, 89% of the alcoholics with a DD genotype developed ACM, whereas only 13% of those with an II or ID genotype developed this condition.

In fact, both molecules are directly cardiotoxic, decreasing structural protein synthesis and heart contractility and increasing oxidative and metabolic damage, leading to autophagy 20,75. In experimental studies, acetaldehyde directly impairs cardiac contractile function 76, disrupts cardiac excitation–contraction coupling, and promotes oxidative damage and lipid peroxidation 20. Acetaldehyde is produced at a lower quantity in the heart as compared to the liver, and systemic acetaldehyde does not achieve toxic heart concentrations 77. In addition, acetaldehyde is Substance abuse able to interact with proteins and produce protein-adduct compounds that are highly reactive and may induce additional inflammatory and immunologic heart damage 78. Therefore, because of its multiple actions, acetaldehyde may influence ACM pathogenesis in addition to ethanol effect itself 20,76,77. A diverse variety of arrhythmias appear early and may worsen the course of ACM, atrial fibrillation being the most frequent 60 and ventricular tachycardia the most deleterious 61.

Alcohol-induced sleep is often shallow and less restorative, leading to feelings of fatigue and reduced alertness during the day. Alcohol’s impact on the body extends to the immune system, compromising its ability to defend against infections and diseases. The immune system is a complex network of cells and proteins that work together to protect the body from alcoholic cardiomyopathy harmful pathogens.

Khanna et al. demonstrated that inducible nitric oxide synthase (iNOS) is increased in cardiomyocytes isolated from rats exposed to 1 month of ethanol (13 g/day, Lieber-DeCarli diet) (42). Increased cardiac tissue iNOS levels can lead to the formation of superoxide and peroxynitrite (16). Ethanol-fed animals had reduced systolic contractility and responses to adrenergic stimuli (isoproterenol) compared to control animals (42). Pharmacological inhibition of iNOS with NG –monomethyl-L-arginine reversed this depression in systolic function and adrenergic signaling. Zhang et al. found significant increases in myocardial protein carbonyl and superoxide levels in mice fed an ethanol (4% v/v) diet for 6 weeks (22). These oxidative stress biomarkers corresponded to myocardial fibrosis development and decreases in fractional shortening and cardiac output.
- Kino et al22 found increased ventricular thickness when consumption exceeded 75 mL/d (60 g) of ethanol, and the increase was higher among those subjects who consumed over 125 mL/d (100 g), without specifying the duration of consumption.
- In experimental studies, acetaldehyde directly impairs cardiac contractile function 76, disrupts cardiac excitation–contraction coupling, and promotes oxidative damage and lipid peroxidation 20.
- It can occur when the heart is unable to pump enough blood to the brain, leading to lightheadedness or a sensation of spinning.
- Chronic, long-term drinking can contribute to malnutrition by replacing foods needed for essential nutrients and by interfering with absorption, storage, or metabolism of the essential nutrients.
Those who struggle with an alcohol use disorder are at significant risk for developing alcoholic cardiomyopathy. Without the ability to maintain proper blood flow, the function of all major organ systems in the body is interrupted. The toxic effects of alcohol abuse can be heart failure, organ failure, or a multitude of other health issues, some more dangerous than others. Alcoholic cardiomyopathy (ACM) is a disease in which the long-term consumption of alcohol leads to heart failure.1 ACM is a type of dilated cardiomyopathy. Alcoholic cardiomyopathy is most common in men between the ages of 35 and 50, but the condition can affect women as well.
