Abstract
BACKGROUND: Inadequate blood pressure (BP) control remains a serious concern worldwide. Recent evidence suggests that the combination of a calcium channel blocker (CCB) with an angiotensin-converting enzyme inhibitor (ACEi) in patients with essential hypertension provides effective BP control with decreased adverse cardiac and renal events. OBJECTIVES: This study was designed to quantitatively evaluate the efficacy and tolerability of a fixed dose combination of perindopril and amlodipine in the Kingdom of Saudi Arabia on a population of patients with essential hypertension, as well as to identify the predictors of BP control in this population. METHODS: This was an observational, multicenter, open-label cohort study of patients with essential hypertension with or without diabetes mellitus, treated with a fixed dose combination of perindopril and amlodipine. Patients were followed up in four-week intervals for a total of 12 weeks. They were initially started on the lowest dose of the ACEi/CCB combination and up-titrated at each follow-up according to their response to treatment. The primary end-point of the study was the percentage of patients with controlled BP at study termination (week 12). RESULTS: A total of 1996 patients completed the study. Both systolic blood pressure (SBP) and diastolic blood pressure (DBP) control was observed in 93.3% of patients at week 12. As for the predictors of BP control, it was found that female gender was associated with more BP control [odds ratio (OR) = 1.76, 95% CI: 1.14-2.70, p value = 0.01], whereas older age was associated with less BP control (OR = 0.98, 95% CI: 0.96-1.00, p value = 0.02). Similarly, having type I and type II diabetes mellitus was also associated with less BP control (OR = 0.19, 95% CI: 0.08-0.45, p < 0.0001 and OR = 0.33, 95% CI: 0.22-0.48, p < 0.0001, respectively). In a qualitative assessment, both investigators and patients perceived efficacy and tolerability of perindopril/amlodipine to be excellent. CONCLUSION: We found that a fixed combination of perindopril/amlodipine is effective in controlling BP in patients with essential hypertension, with older age, male gender, and diabetes mellitus being independent risk factors for less BP control.
