Why the study?
Does exercise arterial pressure waveform analysis provide additional clinical information beyond traditional upper arm cuff methods in predicting cardiovascular risk?
Does exercise arterial pressure waveform analysis provide additional clinical information beyond traditional upper arm cuff methods in predicting cardiovascular risk?
Exercise central arterial pressure waveform analysis may offer superior predictive value for cardiovascular risk compared to traditional cuff blood pressure measurements.
Answers are grounded in this paper and cite their sources.
May refine exercise BP assessment in clinics; leaves open whether waveform analysis improves risk prediction over cuff methods in trials.
Numerous studies in healthy individuals with normal office blood pressure (BP) have shown that a hypertensive response to exercise predicts the future onset of hypertension, as well as cardiovascular morbidity and mortality, independent of office BP. The mechanisms underlying the predictive value of exercise BP are incompletely understood. However, it has been proposed that the additional cardiovascular stress imposed by exercise may unmask the presence of concealed hypertension. A new non-invasive method of exercise arterial pressure waveform analysis (and central BP estimation) may provide additional clinical information, as well as insight into mechanisms, beyond the BP obtained by traditional upper arm cuff methods. 2008 Association for Research into Arterial Structure and Physiology.
