Abstract :
Background: First‑degree relatives (FDRs) of hypertensive (HT) are predisposed to hypertension (HTN) which accelerates
cardiovascular aging. Same can be studied noninvasively by pulse wave analysis (PWA), encompassing central hemodynamics
such as central blood pressure (cBP), cardiac output, and stroke work (SW) and vascular stiffness parameters such as pulse wave
velocity (PWV) and augmentation index at HR 75 (AIx@75). We studied PWA‑derived cardiovascular parameters in FDRs of HT
compared to controls. Materials and Methods: We conducted a case–control study in 119 FDRs of HT and 119 matched controls.
Oscillometric PWA was performed by Mobil‑o‑Graph (IEM, Germany) and cardiovascular parameters were compared. P < 0.05
was considered statistically significant. Results: Groups were comparable with gender, age, height, weight, body mass index, and
physical activity. FDRs of HT had significantly higher brachial and cBPs, SW (101.41 ± 25.44 vs. 88.31 ± 20.25, P = 0.001), rate pressure
product‑119.40 ± 25.34 vs. 108.34 ± 18.17, P < 0.0001), PWV (5.22 ± 0.46, P < 0.0001), and AIx@75 (31.48 ± 9.01 vs. 27.95 ± 9.4,
P = 0.002) than control. Dependent study variables correlated with brachial blood pressure more in magnitude and significance level
than age or anthropometric variables. PWA results of FDR with maternal inheritance did not differ significantly from those with
paternal inheritance. Conclusion: PWA reveals early cardiovascular aging in young FDRs of HTs. It clues to future cardiovascular
disease including HTN itself, need for primary prevention, and further study for consolidation of these results.
