Overview
In patients who continue to abuse alcohol, 4 year survival rate is 50%. On the contrary, abstinence is associated with regression of symptoms and overall improvement.
Natural History
Natural course of alcoholic cardiomyopathy depends on the ability of the patient to abstain from alcohol after being diagnosed. Many case reports and small studies have shown that abstinence from alcohol lead to marked improvement in the clinical condition of the patient. Similarly, conditions of a few patients worsened with continued alcohol intake.[1][2][3][4] Estruch et al found that a positive correlation exists between alcoholic cardiomyopathy and cirrhosis. The study stated that alcoholics who were hospitalized solely for cardiomyopathy had a higher prevalence of cirrhosis than those without heart disease.[5]
Complications
Common cardiovascular complications of chronic alcohol abuse include:
- Congestive heart failure
- Arrhythmias (atrial fibrillation, atrial flutter, supraventricular tachycardias and premature ventricular complexes)
- Hypertension
- Stroke
- Sudden death
Prognosis
Prognosis of alcoholic cardiomyopathy (AC) is worse compared with that of dilated cardiomyopathy. Studies have shown that abstinence results in improvement in clinical condition in AC. In patients who continue to abuse alcohol clinical condition is tend to get worsened, eventually leading to death due to heart failure. 4 year survival rate in patients who continue to consume alcohol is 50%.
