Does alcohol dependence reduce short-term resting-state heart rate variability in individuals without cardiovascular disease?
Alcohol dependence is associated with a medium effect size reduction in short-term resting-state heart rate variability, suggesting a potential mechanism for increased cardiovascular risk.
Quintana et al. (2012) studied this question.
