What is the life expectancy of someone with alcoholic cardiomyopathy?
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. If you have severe symptoms or underlying heart conditions, your provider may recommend a procedure. Providers usually only recommend open-heart surgery or a heart transplant when all other treatments have failed to bring relief.
Among the ACM patients, no differences between the patients in the death and survival groups were observed at baseline with respect to age, disease duration, smoking status, presence of syncope, heart rate, gender, and blood test results. The frequencies of a high New York Heart Association (NYHA; class III/IV) classification, atrial fibrillation (AF) and atrioventricular block were higher in the death group than those in the survival group. Research shows that the prognosis for people with low or moderate consumption should be no different than those who do not drink alcohol at all. There are some diabetes and stroke prevention cures that indicate some benefits to social consumption.
Treatment / Management
If you suspect you at risk of or are suffering from the early stages of alcoholic cardiomyopathy, your doctor will run tests to make an accurate diagnosis. Your doctor will also ask you about your medical history and alcohol use behaviors. It is important to be honest with your doctor about your alcohol use, including the number and amount of drinks you have each day.
They’ll decide your treatment based on which type of cardiomyopathy you have and how advanced it is. In time, your heart can weaken and cardiomyopathy can lead to heart failure. Your doctor might prescribe ACE inhibitors and beta-blockers to help lower your blood pressure.
Conditions such as high blood pressure, valve disease, and arrhythmia (abnormal heart rhythm) can also trigger heart failure. Alcoholic cardiomyopathy may not cause any symptoms until the disease becomes advanced. Alcohol abuse coinciding with myocarditis was reported in 1902 by McKenzie . This review revisits our past and deals with our current thinking on the epidemiology, pathophysiology, clinical characteristics, and treatments available for alcoholic cardiomyopathy. Although anticoagulation may be of benefit to patients with profound LV dysfunction and atrial fibrillation, the risks must be weighed heavily in this patient population.
Cardiomyopathy ranges in severity from causing no symptoms at all to causing exercise intolerance, fatigue, and shortness of breath at rest. Alcoholic cardiomyopathy treatment focuses alcoholic cardiomyopathy on controlling the symptoms as well as preventing them from becoming worse. Now, this can be easier said than done, but doctors can help patients avoid alcohol withdrawal symptoms.
What is alcoholic cardiomyopathy?
It was only after the recent significant increase in alcohol intake that the myocardial dysfunction became apparent. It is unclear whether it was the cumulative dose or the increased daily dose of alcohol that precipitated the left ventricular dysfunction. We reviewed the effects of ethanol on the cardiovascular system in 1996 , including aspects of inflammation , rhythm disturbances , and hypertension . During the first half of the 20th century, the concept of beriberi heart disease (ie, thiamine deficiency) was present throughout the medical literature, and the idea that alcohol had any direct effect on the myocardium was doubted.
