Objective:
The aim of this study was to investigate the acute effects of Shisha Smoking (ShS) on the arterial stiffness, pulse wave velocity (PWV) and other hemodynamic parameters.
Methods:
Ten healthy men (age 31±8 years; mean±SD) were enrolled into this study. Arterial stiffness measurements were investigated by non-invasive Applanation tonometry (Sphygmo-Cor) over the right radial and carotid arteries, while in seated position, after 15 minutes rest, during optimal conditions and at the same durnal time. The measurments for the pulse wave analyses for radial (-ra) and aortic (-ao) blood pressure in mmHg (systolic: SBP, diastolic: DBP, pulse: PP and mean: MBP), heart rate (HR), augmentation pressure (AP), augmentation index (AIx), ejection duration (ED%), subendocardial viability ratio (SEVR%), time of reflection (Tr) and pulse wave velocity (PWV) were taken before (ShS) (after more than 12 hours of smoking cessation with a complete stopping of alcohol, coffee or tea drinking) and repeated after the (ShS) session, which lasted 30 min. for smoking 5 grams of fruit-flavoured tobacco.
Results:
Significant increases in the results after (ShS) were found in HR (p=0.00067), carotid-radial pulse wave velocity (brachial-PWV) (p=0.041), in DBP-ra (p=0.023) but non-significant increases in SBP-ra (p=0.082), MBP-ra (p=0.082), SBP-ao, DBP-ao (p=0.064) and MBP-ao. Significant decreases after (ShS) were found in AP (p=0.0412), AIx (p=0.0257), SEVR% (p=0.00579) and non-significant decrease in (Tr), but an increase in ED% (p=0.00579) was found also.
Conclusions:
The results confirm that Shisha smoking (ShS) has a significant effect on arterial tone and acutly increases arterial blood pressure, heart rate and arterial stiffnes.
