Cigarette smoke, alcohol damage hearts worse as combo
Date:11/21/2007

h, said Shannon Bailey, Ph.D., an associate professor in the UAB Department of Environmental Health Sciences and a co-investigator on the study.

The mice experiments were performed over a five-week period. Blood-alcohol concentrations reached the equivalent of a 150-pound adult consuming 2 drinks per hour. Cigarette smoke exposure was similar to being in an automobile with a chain smoker with the windows closed.

In addition to measuring artery lesions in the study mice, the UAB team looked at other signs of advancing cardiovascular disease like DNA damage and oxidative stress in key heart tissues.

Like the artery lesions, these added measurements showed that taking in both smoky air and ethanol had the effect of basically nullifying any potential heart benefit from drinking alcohol by itself.
