(HealthDay News) — Alcohol abuse increases the risk of atrial fibrillation (AF), myocardial infarction (MI), and congestive heart failure (CHF) as much as other well-established risk factors, according to a study published in the Journal of the American College of Cardiology.
Isaac R Whitman, MD, from University of California, San Francisco, and colleagues assessed the associations between alcohol abuse and AF, MI, and CHF using data from the Healthcare Cost and Utilization Project. A longitudinal analysis was conducted using California residents (≥21 years of age) who received ambulatory surgery, emergency, or inpatient medical care between 2005 and 2009.
Alcohol abuse was present in 1.8% of 14,727,591 patients. After multivariable adjustment, the researchers found that alcohol abuse was associated with an increased risk of incident AF (hazard ratio [HR], 2.14; P < 0.0001), MI (HR, 1.45; P < 0.0001), and CHF (HR, 2.34; P < 0.0001). For the 3 cardiovascular conditions, the population-attributable risk of alcohol abuse was of similar magnitude to other well-recognized modifiable risk factors.
“Those without traditional cardiovascular risk factors are disproportionately prone to these cardiac diseases in the setting of alcohol abuse,” the authors write.
