oa Waterpipe smoking changes cardiovascular hemodynamics in adolescents: The Irbid-TRY

Introduction: Tobacco consumption contributes substantially to cardiovascular (CV) diseases (CVD), including hypertension. However, the effect of waterpipe (WP) smoking on CV hemodynamics in adolescents is unknown. Thus, the current study investigated the relationship of WP smoking with CV indices.

Methods: Indices including heart rate (HR), systolic (SBP), and diastolic (DBP) blood pressures, mean arterial blood pressure (MAP), pulse pressure (PP) and rate pressure product (RPP) were obtained from 7th–10th grade male students.

Results: After controlling for confounding factors, SBP, DBP, MAP, and RPP were significantly lower (p < 0.05) in WP smokers versus non-smokers.

Conclusion: The results indicate that WP smoking lowers CV hemodynamics, which is perplexing given that tobacco smoking is associated with an immediate increase in CV hemodynamics and CVDs in adulthood. Therefore, future studies are needed to determine the mechanism(s) for lowered CV hemodynamics and the pathway between WP smoking and heightened risk of developing CV diseases adulthood, namely hypertension.
