Exercise-induced systolic BP reserve (mean rise 31.7 mmHg) and pulse rate reserve (mean rise 62.8 beats/min) were significantly associated with cardiac structure and diastolic function.

Do exercise-induced changes in blood pressure and pulse rate measured by a wearable device correlate with cardiac structure and function in mixed hypertensive and normotensive individuals?
Wearable oscillometric blood pressure monitors can effectively track dynamic hemodynamic responses during exercise, which correlate with echocardiographic measures of cardiac structure and function.
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. Design and method: 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, peak exercise and during recovery using HUAWEI WATCH D2, with reserves calculated as peak minus rest values. Cardiac structure and diastolic 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, systolic BP rose by 31.7 (± 17.5) mmHg (from 119.9 mmHg at basal to 151.7 mmHg at maximal), diastolic BP 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, systolic BP reserve were significantly associated with cardiac structural, but not with most functional measurements. Pulse rate reserve were negatively associated with cardiac structural measurements, and positively associated with diastolic function. These observed associations tended to be stronger in women. Conclusions: Wearable BP monitors can trace dynamic hemodynamic responses to exercise. The exercise-induced changes in pulse rate and systolic BP are associated with cardiac structure and function, especially in women.
Chen et al. (Fri,) conducted a observational in Hypertension and normotension (n=137). Exercise-induced changes in blood pressure and pulse rate was evaluated on Associations of exercise-induced changes in blood pressure and pulse rate with cardiac structure and diastolic function. Exercise-induced systolic BP reserve (mean rise 31.7 mmHg) and pulse rate reserve (mean rise 62.8 beats/min) were significantly associated with cardiac structure and diastolic function.
