Abstract
Introduction: Tobacco causes acute rise in blood pressure, but long-term effects are not well established. Non dipper pattern and nocturnal arterial hypertension are associated with higher cardiovascular risk.
Aim: Evaluate the association between intensity of tobacco consumption and arterial hypertension control.
Methods: Descriptive, analytical study. Sample: adults, smokers and hypertensive patients with ambulatory blood pressure monitoring. Variables: number or cigarettes consumed/day, pack-year index, blood pressure variability patterns and nocturnal arterial hypertension. Median and range were used. Variable correlation study, Spearman’s test. Significance level 0.05.
Results: Total hypertensive patients (391). Current smokers and hypertensive (56): female sex 64,9% (37); patterns: dipper (27), non dipper (14), extreme dipper (10), riser (5).
Patients with non dipper pattern had a median consumption of 15 cigarretes/day, being statistically higher than patients with dipper pattern, median of 3 (p 0.017). An association was found between higher pack-year index and non dipper pattern, median 33, in relation to a dipper pattern, median of 10 (p 0.017).
42.9% (24) had nocturnal arterial hypertension. A trend is observed between higher pack-year index and greater intensity of cigarette consumption/day, with the presence of nocturnal hypertension (p value-0.106 and p-0.401, respectively). Limitations: low number of smokers included.
Conclusions: The intensity of tobacco use could be associated with blood pressure variability patterns with a higher cardiovascular risk. This suggests that smoking cessation could be important for the control of arterial hypertension.
