Objective: To study the effect of different classes and combinations of antihypertensive agents on arterial stiffness and central hemodynamic parameters. Materials and Methods: A cross-sectional study was conducted in 446 treated apparently healthy hypertensives. Oscillometric PWA was performed by Mobil-o-Graph (IEM, Germany) to derive cardiovascular parameters that were further analyzed in groups stratified by antihypertensive used. Study parameters were brachial hemodynamics (blood pressure (BP), heart rate, and rate pressure product); arterial stiffness (augmentation pressure, augmentation index, pulse wave velocity, total arterial stiffness, and pulse pressure amplification); and central hemodynamics (central BP, cardiac output, and stroke work). Statistical significance was kept at P < 0.05. Results: All groups were selected by matching of age, gender, and body mass index. They were comparable with major confounding factors. There was no difference between study parameters in hypertensives taking exclusive angiotensin-converting enzyme inhibitor (ACEI), calcium channel blocker (CCB), or angiotensin II receptor blocker. Multitherapy showed better hemodynamics and monotherapy showed better stiffness parameters. Addition of CCB to ACEI did not make a difference except with diastolic BP. For most comparisons, most of the results lacked statistical significance. Conclusion: Discrete PWA parameters showed no class difference in hypertensives, treated by conventional monotherapy or combination, ACEI appears to be the best drug. This also indicates that early diagnosis and blood pressure control are more important than antihypertensive used.
