Key result
Young adults with suboptimal blood pressure had a reduced left ventricular ejection fraction response to exercise (p=0.001), which was predicted by resting left atrial booster pump function (p=0.011).
Why the study?
To investigate the left ventricular response to exercise in young adults with hypertension, and identify whether this response can be predicted from resting left atrial function changes.
Does suboptimal blood pressure alter the left ventricular response to exercise, and can this response be predicted by resting left atrial function in young adults?
Cross-Sectional (n=127)

p-value: p=0.001
Resting left atrial booster pump function can predict a reduced left ventricular systolic response to exercise in young adults with suboptimal blood pressure, serving as an early marker of subclinical cardiac remodeling.

May flag early subclinical LV impairment in young adults with suboptimal BP; hypothesis-generating for LA booster pump as predictor.
Alsharqi et al. (2021) conducted a cross-sectional in suboptimal blood pressure (n=127). Suboptimal blood pressure (≥120/80 mm Hg) vs. Optimal blood pressure (<120/80 mm Hg) was evaluated on Rise in left ventricular ejection fraction during exercise (p=0.001). Young adults with suboptimal blood pressure had a reduced left ventricular ejection fraction response to exercise (p=0.001), which was predicted by resting left atrial booster pump function (p=0.011).
