Objective
Our objective was to evaluate a triple-drug antihypertensive strategy for blood pressure control in patients with difficult-to-treat hypertension.
Design
The Perindopril-Indapamide plus AmlodipiNe in high rISk hyperTensive patients (PIANIST) trial was an observational, 4-month, open-label study.
Patients and interventions
A total of 4,731 patients at high or very high cardiovascular risk with hypertension that was not properly controlled despite antihypertensive therapy, and for whom study treatment (fixed-dose perindopril 10 mg/indapamide 2.5 mg + amlodipine 5 or 10 mg) was consistent with their existing therapeutic plan, were included.
Outcomes
One-sample t tests and Chi-squared tests were performed to evaluate changes in blood pressure.
Results
Mean baseline office blood pressure (OBP) was 160.5 ± 13.3/93.8 ± 8.7 mmHg. After 4 months of therapy, OBP decreased by 28.3 ± 13.5/13.8 ± 9.4 to 132.2 ± 8.6/80.0 ± 6.6 mmHg (p < 0.0001). Blood pressure targets were reached by 72.0 % of patients and by 81 and 91 % of patients previously treated with an angiotensin-converting enzyme inhibitor/hydrochlorothiazide or an angiotensin receptor blocker/hydrochlorothiazide, respectively. Changes in OBP were 18.7 ± 8.3/9.7 ± 7.2 mmHg for grade 1 (n = 1,679), 30.4 ± 10.1/14.7 ± 8.6 mmHg for grade 2 (n = 2,397), and 45.4 ± 15.1/20.7 ± 12.1 mmHg for grade 3 patients (n = 655; all p < 0.0001). In patients who underwent ambulatory blood pressure monitoring (n = 104), 24-h mean blood pressure decreased from 147.4 ± 13.8/82.1 ± 11.9 to 122.6 ± 9.1/72.8 ± 7.4 mmHg (p < 0.0001). Ankle edema was infrequent (0.2 % of patients).
Conclusion
Triple combination perindopril/indapamide/amlodipine was effectively and safely administered to a large population of high- and very high-risk hypertensive patients who had not reached target OBP values with previous treatment.
