ObjectiveTo assess the prevalence of high central aortic pressure (CAP) in Indian patients with uncontrolled essential hypertension while on anti-hypertensive monotherapy. Also, to determine correlation between brachial blood pressure (BBP) and CAP, and ascertain if it is impacted by anti-hypertensive drug class and patients’ age.MethodsIn this real-world, observational, prospective study, patients (30–70 years) with uncontrolled BBP (systolic BP [SBP] ≥140 mmHg or diastolic BP [DBP] ≥90 mmHg) were enrolled. Treatment was adjusted at Visit 1 (baseline), based on BBP and at treating physicians’ discretion. Primary endpoint was proportion of patients with uncontrolled central aortic SBP (>125 mmHg) at baseline. Secondary endpoints were comparison of BBP and CAP across drugs classes and age groups at baseline and Visit 2 (End-of-study, ∼8 weeks post-baseline), and proportion of patients with uncontrolled central SBP at end-of-study.ResultsOf 2030 patients screened, 1949 patients reported at baseline and 1740 patients completed end-of-study visit. Central SBP was >125 mmHg for 84.3% patients at baseline, and 48% patients at end-of-study. Interestingly, at end-of-study, 6.6% patients still had uncontrolled brachial SBP and controlled central SBP, while 13.6% patients had uncontrolled central SBP and controlled brachial SBP. At both visits, brachial SBP and central SBP showed positive correlation across most drug classes and age groups. At baseline, ACE inhibitors showed better efficacy than other drug classes. At end-of-study, BP control was better with fixed-dose combinations, though free–drug combinations were more frequently prescribed.ConclusionMeasurement of CAP along with BBP can be vital in management of hypertension.Ctri registration numberCTRI/2015/10/006302.
