Previous studies were conducted on rats that are fed alcohol for about eight months. They found that there is about 14% loss of myocardial cells in the left ventricle of those rats. It showed a significant increase in both acute and alcoholic cardiomyopathy symptoms chronic alcohol intoxication.
General Health
- Over time, this damage can lead to the enlargement of the heart and the development of heart failure.
- Around 40–80% of people with ACM who continue drinking alcohol die within 10 years of their diagnosis.
- This holistic approach extends beyond medical treatment to encompass ongoing support for those dealing with substance abuse and addiction.
- These changes, though subtle, were similar to those found by Ferrans and Hibbs in eight deceased individuals diagnosed with ACM42,43.
Palpitations, dizziness, and syncope are common complaints and are frequently caused by arrhythmias (eg, atrial fibrillation, flutter) and premature contractions. In the setting of acute alcohol use or intoxication, this is called holiday heart syndrome, because the incidence is increased following weekends and during holiday seasons. 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. Ask any patient presenting with new heart failure of unclear etiology about their alcohol history, with attention to daily, maximal, and lifetime intake and the duration of that intake. Between 40% and 80% of individuals who continue to drink heavily post-diagnosis may not survive more than 10 years. Unfavorable prognostic factors include the presence of atrial fibrillation, significant widening of QRS complexes (exceeding 120 ms), and the absence of beta-blocker therapy.
Your outlook may also improve depending on other treatments you receive, such as medication or surgery. While alcohol-induced cardiomyopathy comes from long-term alcohol abuse, there’s no universal limit or number that means you’ll develop it. However, researchers have pinpointed certain behaviors that make it more likely you’ll develop this condition. Changes in your heart’s shape can also disrupt that organ’s electrical system. An electrical current travels through your entire heart with every heartbeat, causing each part of the heart to squeeze in a specific sequence.
Some conditions that can worsen outcomes include heart rhythm issue known as atrial fibrillation, a prolonged QRS waveform on a heart monitor, and not taking medication called beta-blockers. The primary treatment for ACM involves complete abstinence from alcohol or other drugs. However, some studies show that moderating alcohol consumption may lead to similar health outcomes. Your doctor might prescribe ACE inhibitors and beta-blockers to help lower your blood pressure. If your heart is severely damaged, your doctor may recommend an implantable defibrillator or pacemaker to help your heart work. They commonly include fatigue, shortness of breath, and swelling of the legs and feet.

Alcohol-induced toxicity can result in non-ischemic dilated cardiomyopathy characterized by the loss of contractile function and the dilatation of myocardial ventricles. These pathophysiological changes are typically observed in individuals with a history of heavy alcohol consumption in the absence of coronary artery disease as an underlying cause. Askanas et al21 found a significant increase in the myocardial mass and of the pre-ejection periods in drinkers of over 12 oz of whisky (approximately 120 g of alcohol) compared to a control group of non-drinkers. However, no differences were found in these parameters between the sub-group of individuals who had been drinking for 5 to 14 years and the sub-group of individuals who had a drinking history of over 15 years. In another study on this topic, Lazarević et al23 divided a cohort of 89 asymptomatic individuals whose consumption exceeded 80 g/d (8 standard units) into 3 groups according to the duration of their alcohol abuse.
- Alcoholic cardiomyopathy is much less common among females who account for only 14% of cases, although it should be said that the amount of alcohol that can cause alcoholic cardiomyopathy appears to be less.
- Next, we established inclusion and exclusion criteria to determine the eligibility of articles.
- Our bodies, our hearts, tell us when it’s absolutely time for a lifestyle change.
- In more severe or complicated cases, especially ones involving surgery, some symptoms may not improve for even longer.

Furthermore, in many of these reports, comorbid conditions, especially myocarditis and other addictions such as cocaine and nicotine, were not reported. Ballester specifically analysed the effects of alcohol withdrawal on the myocardium using antimyosin antibodies labelled with Indium-11172. This radiotracer has been acknowledged as an indicator of irreversible myocardial damage. Of the 56 patients included in the study, 28 were former drinkers and 28 continued consuming alcohol during the study.
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.
- Individuals with a history of high blood pressure (hypertension) are at higher risk because the heart has to work harder to pump blood, worsening alcohol-induced damage.
- It’s important to note that alcoholic cardiomyopathy may not cause any symptoms until the disease is more advanced.
Echocardiographic and haemodynamic studies in alcoholics
If a person stops drinking, the damage to the heart muscle can be reversed. It is important to note, however, that the damage can be irreversible in some cases. In addition to abstaining from alcohol, making lifestyle changes such as eating a healthy diet, exercising, and avoiding stress can help improve heart health and reverse ACM.

Her most recent admission with pancreatitis had occurred four months before the present admission. If you notice any of these symptoms, contact your doctor as soon as possible. The sooner you can get treatment for this condition, the lower your risk of heart damage and loss of function. Even if cardiomyopathy isn’t part of your family history, it’s still important to take steps to make sure you don’t develop a heart condition or disease that could put you at an increased risk of cardiomyopathy. Other than destroying the liver and gut, alcohol also can have adverse effects on the heart.
But, daily drinking of around 80 grams of alcohol or more for over 5 years can significantly increase the risk. Despite this, not everyone who drinks heavily and regularly will develop this alcohol-induced heart condition. The exact biochemical and physiological mechanisms underlying the symptoms of alcoholic cardiomyopathy remain a subject of ongoing research.
In general, most people who stop drinking alcohol will feel better over the next three to six months. However, certain symptoms may start to improve even sooner, depending on treatments and the severity of your case. In more severe or complicated cases, especially ones involving surgery, some symptoms may not improve for even longer. Overall, your healthcare provider is the best source of information and answers when it comes to your recovery.
The Sobriety only way to cure alcohol-induced cardiomyopathy is with a heart transplant. 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.
