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. Improvement in cardiac function evident from echocardiographic findings can also be noted.
Natural History, Complications and Prognosis
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
The prognosis of alcoholic cardiomyopathy is better compared with that of idiopathic dilated cardiomyopathy; approximately 2/3 of the patients are stable. Poor prognostic factors include atrial fibrillation, wide QRS, and lack of beta blocker therapy.[6]
Studies have shown conflicting results regarding the effect of abstinence or reduction in alcohol intake on clinical outcomes in alcoholic cardiomyopathy.[6][7] According to one study, the four-year survival rate in patients who continue to consume alcohol was reported to be 50%.[7]
