Key result
Hypertension in the elderly was associated with decreased heart rate variability, including a lower SDNN (43.15 vs 58.35 ms, p=0.030) compared to healthy normotensive controls.
Why the study?
Does hypertension reduce heart rate variability and parasympathetic modulation in the elderly compared to normotensive controls?
Cross-Sectional (n=80)
Does hypertension reduce heart rate variability and parasympathetic modulation in the elderly compared to normotensive controls?
Absolute Event Rate: 43.15% vs 58.35%
p-value: p=0.030
Hypertension in the elderly is associated with reduced heart rate variability and decreased parasympathetic modulation, indicating impaired cardiac autonomic function.

HRV parameters were associated with blood pressure in elderly; leaves open predictive value or therapeutic role.
Andrade et al. (2017) conducted a cross-sectional in Hypertension (n=80). Hypertension vs. Healthy normotensive elderly was evaluated on Heart rate variability (SDNN) (p=0.030). Hypertension in the elderly was associated with decreased heart rate variability, including a lower SDNN (43.15 vs 58.35 ms, p=0.030) compared to healthy normotensive controls.
