Study Summary
Hookah (water-pipe) tobacco smoking has quickly grown to become a major global tobacco epidemic among youth; with electronic (e-) hookahs more recently increasing in popularity especially among young female adults, who endorse marketing claims that these products are a safer alternative to traditional hookah, but scientific evidence is lacking. The study aims to elucidate the comparative effects of traditional hookah smoking vs. e-hookah vaping on human vascular and endothelial function; and examine the role of inflammation and oxidative stress, as likely mechanisms in hookah-related cardiovascular disease pathogenesis.
Primary Outcome
Using ultrasound, FMD of the brachial artery induced by reactive hyperemia, was used to measure endothelium-dependent vasodilator function. Baseline diameter and velocity were recorded for 45 seconds and resumed 30 seconds before cuff deflation and continuously for 2 minutes after deflation to obtain true peak vasodilatory response.
Interventions
- OTHER Traditional hookah smoking
- OTHER Electronic hookah vaping
