Abstract Background Arterial stiffness and hypertension are strong predictors of cardiovascular disease and mortality. Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) are first-line antihypertensive agents in reducing blood pressure and arterial stiffness. Objective The objective of this study was to compare the effects of ACEI and ARB in reducing arterial stiffness and preventing target organ damage in patients with hypertension. Methods This observational study included 654 participants who attend routine consultations at an outpatient hypertension clinic in 2 university hospitals. Patients were interviewed, and they underwent central and peripheral blood pressure measurements. Doppler echocardiography, carotid ultrasound, biochemical tests, and anthropometric parameters were carried out. Shapiro-Wilk, chi-square, and Fisher's exact test were used. A significance level of 5% was adopted. Results A total of 659 participants were evaluated in the study (398 from the ARB group and 256 from the ACEI group). Age, body mass index (BMI), central and peripheral blood pressure measurements, pulse wave velocity (PWV), left ventricular mass index, and carotid intima-media thickness did not show differences between the groups (p > 0.05). After linear regression analysis, the ACEI group had lower values of total vascular resistance (TVR) (p = 0.003) and augmentation pressure (p = 0.008), when compared to the ARB group. Conclusion This study showed that the ACEI group had a greater reduction in augmentation pressure and PWV. There were no differences between the groups regarding the improvement of outcomes related to central arterial pressure, PWV, and cardiac and vascular target organ damage.
