BACKGROUND: Alcohol has been implicated as a risk factor for idiopathic dilated cardiomyopathy (DCM), but a causal relation has not been established. The objective of this study was to determine the association between alcohol consumption and DCM.
METHODS: Questionnaires detailing average weekly intake of alcohol, total lifetime consumption, and alcohol abuse were administered in a cohort of well-defined patients with DCM and a randomly selected, population-based control group.
RESULTS: Significantly more of the 100 patients with DCM than the 211 members of the control group drank greater than the recommended weekly intake of alcohol (40% vs 24%; p<0.01) and were alcohol abusers according to the CAGE questionnaire (27% vs 16%; p<0.05). The average total lifetime consumption measured in units of alcohol was also significantly greater in cases than in the control group (31,200 vs 7,904; p<0.01). Patients with familial DCM were not significantly more likely to consume alcohol above recommended limits or to be alcohol abusers compared with nonfamilial cases.
CONCLUSIONS: This study confirms previous suspicion of a causal association between alcohol and DCM, with significantly more patients than members of the control group either abusing alcohol or drinking it in excess of recommended limits.
