Use of Antihypertensive Drugs and Arterial Stiffness in the Longitudinal Study of Adult Health (ELSA-Brasil).

Objective: Evaluate the longitudinal association between BP control and the use of antihypertensive classes with arterial stiffness (AS) in Brazilian adults.

Methods: This study included 1830 participants with arterial hypertension (1092 participants with controlled BP and 738 participants with uncontrolled BP) from the Longitudinal Study of Adult Health (ELSA-Brasil). AS was assessed by pulse wave velocity (PWV) and pulse pressure (PP) at baseline and repeated after approximately 9 years. Associations between AS and BP control and the use of antihypertensives, diuretics, angiotensin-converting enzyme inhibitors (ACEI), AT1 receptor blockers (ARB), calcium channel blockers (CCB), and beta blockers (in the population with controlled BP), at baseline were investigated using linear mixed-effects models.

Results: Uncontrolled BP was associated with worse PWV and PP trajectory, respectively (β = 0.026 [0.008 to 0.036] / β = 0.273 [0.216 to 0.330]). Among the participants with controlled BP, using CCB (β = 0.031 [0.011 to 0.051]) was associated with a worse PWV trajectory, compared to not using this class and this combination, respectively.

Conclusion: BP control, regardless of the class of antihypertensive used is associated with a better AS trajectory, as assessed by PWV and PP. Among participants with controlled BP, the use of BCC, compared to not using this class, seems to be worse for the trajectory of PWV in individuals with arterial hypertension without cardiovascular disease. Further studies are needed to assess whether this effect results in a better prognosis for patients with arterial hypertension.
