Cigarette smoking and hypertension are significant cardiovascular risk factors. The effect of
cigarettes on blood pressure and the development of hypertension are unclear. Studies on the
subject report contradictory results. The purpose of this study was to investigate the effect of
cigarette smoking on blood pressure and hypertension. Our study population consisted of 712
patients with a mean age of 51.2±15.1 years, 44% of them were male and 56% of them were
female. Thirty-six percent of patients were smokers, 9% of them were ever smoked and stopped
smoking or ex-smoker and 55% of them were nonsmoker. Systolic and diastolic blood pressures
were lowest in the smokers, higher among ex-smokers compared to smokers and highest in the
non-smokers (P<0.001). The mean systolic and diastolic blood pressures were 119/74 mmHg in
the smokers, 134/81 mmHg in the ex-smokers and 150/88 mmHg in the non-smokers.
Prevalence of hypertension did not change by smoking status. A significant variation was
determined, at 15% in smokers, 33% in ex-smokers and 55% in non-smokers (P<0.001). In
conclusion, blood pressures and prevalence of hypertension were significantly low in smokers in
this study. Despite the limitless harm it has, cigarette smoking exhibits a lowering effect in blood
pressure, although the mechanism involved is unclear.
