Alcoholic Cardiomyopathy: Overview, Cardiac Effects of Alcohol, Quantity of Alcohol Intake in Cardiac Disease

Your healthcare provider is the best person to explain the risks and possible complications that you might face from this condition itself, related health concerns or any of the treatments that you will receive. As you reduce your alcohol intake, your provider will also treat your symptoms. This usually involves certain types of medications that treat heart rhythm problems or other symptoms of heart failure. Those who don’t fully recover are also likely to need this kind of treatment indefinitely.

Basic studies on molecular mechanisms of myocardial damage

The onset of symptoms is usually insidious, but acute decompensations are also observed, especially in patients with asymptomatic left ventricular dysfunction who develop atrial fibrillation or other tachyarrhythmia and, because of this, are unable to increase their cardiac output. Alcoholic cardiomyopathy (ACM) is a type of heart disease that can result from chronic alcohol consumption. Experts do not know what quantity of alcohol a person needs to consume to develop ACM. They also have not identified the minimum length of time someone needs to drink alcohol before developing the condition. Pharmacologic therapy should include goal-directed heart failure therapy as used in idiopathic dilated cardiomyopathy with reduced ejection fraction.

When to see a doctor

• Basic research studies have described an abundance of mechanisms that could underscore the functional and structural alterations found in ACM.
• In a subsequent study using electron microscopy, the authors found histological features that could be superimposed onto those found in hearts that had suffered hypoxia, anoxia or ischemia[43].
• Echocardiogram usually reveals left ventricular hypertrophy, depressed left ventricular ejection fraction, and dilation.

This may be explained by the fact that the increased catalase activity in those who have a long history of alcohol abuse may represent a protective and adoptive reaction to the persistent high ethanol levels [11]. For many people, abstaining from alcohol can lead to a full recovery, especially when your case is less severe. However, for others, the effects of alcohol-induced cardiomyopathy may be life-long. Even alcoholic cardiomyopathy in cases where people can undergo a heart transplant, individuals with a history of alcohol-induced cardiomyopathy are more likely to face other health problems down the road. A repeat echocardiogram revealed normal left ventricular function, with an ejection fraction of 62% by modified Simpson’s biplane method. The end-systolic dimension was 3.3 cm and the end-diastolic dimension was 4.8 cm (Figure 2).

How to Prevent Heart Failure

The patient’s delirium tremens was treated with benzodiazepines, and her congestive heart failure was treated with diuretics and an angiotensin-converting enzyme (ACE) inhibitor. The pancytopenia and elevated liver enzyme levels resolved within a few days of hospital admission, with abstinence from alcohol. A dipyridamole stress test performed seven days after admission revealed no myocardial ischemia. The patient’s ejection fraction was calculated at 58%, and she was discharged on a diuretic, an ACE inhibitor and a beta-blocker.

• Furthermore, there are conflicting data among studies regarding the prognosis of the condition, with some showing overall mortality near 60% and others showing a mortality rate of only 19% (Table ​(Table11).
• Kino et al[22] 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.
• She admitted to an eight-year history of the ingestion of more than 600 mL of vodka per day.
• Muscular weakness may also be present because of the effect of alcohol on muscles (alcoholic myopathy).
• In general, you should talk to your healthcare provider if you notice changes in your symptoms over time, especially if they are starting to affect your normal life and routine.
• Unfortunately Lazarević et al[23], as in most of these studies, systematically excluded patients with a history of heart disease or with HF symptoms.

Not only have medications in these four drug classes been shown to improve heart pump function, but they also reduce hospitalizations and can help reduce your risk of dying from heart failure. This article will discuss heart failure, how it can be prevented or reversed, and the outlook for people with the condition. Despite these features, the structural changes do not seem to be specific, furthermore, they are not qualitatively different from those found in idiopathic DCM and they do not allow us to differentiate between the two conditions[44].

• For patient education information, see the Mental Health Center, as well as Alcoholism, Alcohol Intoxication, Drug Dependence and Abuse, and Substance Abuse.
• However, several pitfalls in the pathophysiology, natural history, diagnosis and risk stratification of this disease still exist.
• Accordingly, a given amount of alcohol is administered to volunteers or alcoholics, followed by the measurement of a number of haemodynamic parameters and, in some cases, echocardiographic parameters.
• It is largely unknown which factors determine cardiac toxicity on exposure to alcohol.

Maintaining a stable cardiac status in the setting of a myopathy is challenging for both the patient and clinician. Adherence to a medication requires reminders from the patient and the practice. Smartphone apps designed to improve adherence are helpful, particularly those that have periodic voice communication. https://ecosoberhouse.com/ But any simple phone app that provides a reminder to the patient to take the medication is beneficial. A colleague working in the publishing industry asked if I’d see his 30-year-old son for a medical evaluation. A business executive in Philadelphia, the son was in good health with no prior illness.

We’re transforming healthcare

This includes a combination of beta-blockers, an angiotensin-converting enzyme inhibitor, diuretics, aldosterone receptor antagonist and angiotensin blocker-neprilysin inhibitor (if LVEF is less than or equal to 40%). The use of carvedilol, trimetazidine with other conventional heart failure drugs have been proven to be beneficial in some studies. Alcoholic cardiomyopathy can present with signs and symptoms of congestive heart failure. Symptoms include gradual onset worsening shortness of breath, orthopnea/paroxysmal nocturnal dyspnea. Palpitations and syncopal episodes can occur due to tachyarrhythmias seen in alcoholic cardiomyopathy. Long-term alcohol abuse weakens and thins the heart muscle, affecting its ability to pump blood.

It’s very important to stick with the treatment plan and to stop drinking alcohol during recovery. ARBs work similarly to ACE inhibitors and block angiotensin II from attaching to angiotensin II receptors. This helps lower blood pressure as well as the likelihood of damage occurring to the heart, blood vessels, and kidneys. The side effects of these drugs include dizziness, angioedema, and a rise in potassium blood levels (hyperkalemia). Heart failure is a chronic condition that, if untreated, typically gets progressively worse over time. With advances in medical technology and more knowledge about how heart failure develops, most people no longer receive one-size-fits-all treatment for heart failure.
