Key result
In hypertensive patients with preserved ejection fraction, left atrial minimum volume was an independent predictor of high resting heart rate.
Why the study?
Does a resting heart rate >70 beats/min associate with worse global left ventricular longitudinal strain and left atrium structural/functional changes in hypertensive patients with normal LVEF?
Case-Control (n=153)
No
Does a resting heart rate >70 beats/min associate with worse global left ventricular longitudinal strain and left atrium structural/functional changes in hypertensive patients with normal LVEF?
In hypertensive patients with preserved LVEF, a resting heart rate >70 bpm is independently associated with structural and functional alterations in the left atrium.

LA minimum volume may flag elevated resting heart rate risk in preserved-EF hypertension; hypothesis-generating and should not yet change practice.

Yerlikaya et al. (2024) conducted a case-control in Hypertension with normal left ventricular ejection fraction (n=153). Resting heart rate > 70 beats/min vs. Resting heart rate ≤ 70 beats/min was evaluated on High resting heart rate (>70 beats/min) predicted by left atrial minimum volume (OR 0.870, 95% CI 0.809-0.938, p=<0.001). In hypertensive patients with preserved ejection fraction, left atrial minimum volume was an independent predictor of high resting heart rate.
