Electronic cigarette (e-cigarettes) vaping may pose just as much or even higher risk as smoking tobacco for worsening a stroke, according to a preliminary study in mice presented at the American Heart Association's International Stroke Conference 2017.

Researchers found:

Mice exposed to e-cigarette vapor for 10 days or 30 days had worse stroke outcome and neurological deficits, than those exposed to tobacco smoke.

E-cigarette exposure decreased glucose uptake in the brain. Glucose fuels brain activity.

Both e-Cig and tobacco smoke exposure for 30 days decreased Thrombomodulin (anti-coagulant) levels.

From a brain health perspective, researchers said, electronic-cigarette vaping is not safer than tobacco smoking, and may pose a similar, if not higher risk for stroke severity.

Use of e-cigarettes is a growing health concern in both smoking and nonsmoking populations. Researchers said rigorous studies are needed to investigate the effects of the nicotine exposure via e-cigarettes on brain and stroke outcome.
