Key result
Uncontrolled blood pressure in hypertensive patients was associated with significantly lower heart rate recovery at 1 minute post-exercise compared to controlled blood pressure (23.88 vs 27.13 bpm).
Why the study?
Is uncontrolled blood pressure associated with lower heart rate recovery in hypertensive patients taking antihypertensive medications?
Observational (n=279)
No

Absolute Event Rate: 23.88% vs 27.13%
p-value: p=0.018
Uncontrolled blood pressure in hypertensive patients is associated with delayed heart rate recovery, suggesting worse autonomic dysfunction compared to those with controlled blood pressure.
No takes yet. Share an insight, caveat, or question.
May indicate greater autonomic dysfunction with uncontrolled BP; leaves open causality and requires prospective confirmation.
Yu et al. (2016) conducted an observational in Essential hypertension (n=279). Uncontrolled blood pressure vs. Controlled blood pressure was evaluated on Heart rate recovery at 1 minute post-exercise (HRR1) (p=0.018). Uncontrolled blood pressure in hypertensive patients was associated with significantly lower heart rate recovery at 1 minute post-exercise compared to controlled blood pressure (23.88 vs 27.13 bpm).
