Key result
Wearable-measured exercise SBP and HR changes link to cardiac structure and function, especially in women.
Why the study?
This study investigated exercise-induced changes in blood pressure and pulse rate measured with a wearable oscillometric monitor and their associations with echocardiographic cardiac structure and function.
Are exercise-induced changes in blood pressure and pulse rate measured by a wearable monitor associated with cardiac structure and function?

Are exercise-induced changes in blood pressure and pulse rate measured by a wearable monitor associated with cardiac structure and function?
Wearable wrist-type oscillometric blood pressure monitors can effectively trace hemodynamic responses to exercise, which correlate with echocardiographic measures of cardiac structure and function.
May support wearable exercise BP monitoring for cardiac insights; leaves open prospective validation before clinical use.
Objective: This study investigated the exercise-induced changes in blood pressure (BP) and pulse rate using a wearable oscillometric BP monitor and their associations with cardiac structure and function. Methods: The study included 137 participants (mixed hypertensive and normotensive) who underwent standardized symptom-limited cycle ergometer testing. BP and pulse rate were measured at rest, at peak exercise, and during recovery using HUAWEI WATCH D2, with reserves calculated as the peak minus rest values. Cardiac structure and function were assessed by echocardiography. Results: The study participants had a mean age of 36.7 years, and included 63 women (46.0%) and 69 patients with hypertension (50.4%). During exercise, SBP rose by 31.7 (± 17.5) mmHg (from 119.9 mmHg at basal to 151.7 mmHg at maximal), DBP by 4.9 (± 9.4) mmHg (from 79.0 to 84.0 mmHg), and pulse rate by 62.8 (± 18.6) beats/min (from 81.4 to 149.6 beats/min). After adjustment, SBP reserve was significantly associated with cardiac structure ( P ≤ 0.024), but only with stroke volume ( P =0.048) among the functional measurements ( P ≥ 0.443). Pulse rate reserve were negatively associated with cardiac structural measurements ( P ≤ 0.046), and positively with diastolic function ( P ≤ 0.048). These observed associations tended to be stronger in women. Conclusion: Wearable BP monitors can trace hemodynamic responses to exercise. The exercise-induced changes in pulse rate and SBP are associated with cardiac structure and function, especially in women.

Zhou et al. (2026) conducted an observational in mixed hypertensive and normotensive (n=137). Exercise-induced changes in blood pressure and pulse rate was evaluated on Association of systolic blood pressure reserve with cardiac structure (p=≤0.024). Exercise-induced changes in systolic blood pressure and pulse rate measured by a wearable monitor were significantly associated with cardiac structure (P≤0.024) and function, especially in women.
