“…This result is in agreement with the reported values previously [20] in which auscultatory diastolic blood pressure was higher 4 mmHg than that measured by the intra-arterial method. Aerobic exercise dilates muscular arteries and reduces arterial pressure augmentation [21], an effect that will ultimately enhance ventricular-vascular coupling and reduce the pressure load on the left ventricle.…”

Objectives: This study tested whether the systolic and diastolic blood pressures measured simultaneously by direct and indirect methods provide similar readings for blood pressure response during symptom-limited exercise on a treadmill and bicycle, and if it can be used to monitor blood pressure in hypertensive patients treated with β-blockers. Method:Comparisons were made with simultaneously determined intra-arterial catheter and auscultation measurements on a treadmill and bicycle. Eight hypertensive patients (41.9 ± 2.0 years) active participants in supervised aerobic programs (12.1 ± 1.2 METs work capacity) for at least 12 months were recruited to the study.Results: At rest, indirect systolic pressure was highly correlated with the direct method (r=0.85), with mean of 139 ± 7 and 134 ± 6 mmHg, respectively, at peak treadmill exercise (r=0.90), with mean of 198 ± 11 and 189 ± 9 and bicycle (r=0.92) with mean of 204 ± 10 196±9 mmHg respectively. Indirect diastolic blood pressure correlates well with intra-arterial at rest (r=0.82), with mean of 96 ± 11 and 88 ± 9 mmHg, respectively. However, at peak treadmill exercise, the correlation coefficient between the direct and the indirect methods was low (r=0.40), with mean of 105 ± 9 and 112 ± 12 mmHg, respectively. At peak bicycle exercise correlation was (r=0.58) with mean of 107 ± 9 and 112 ± 12 mmHg. Conclusions:These results suggest that at peak treadmill exercise and bicycle, the indirect method tends to bias low compared with direct therefore it is not valid for the assessment of diastolic pressure in hypertensive patients. Intensity should be considered when using cardiovascular variables as outcome measures.

“…There are different systems able to look at the reflected waves and estimate the tone of the arterial tree, i.e. Pulsecor and SphygmoCor [23][24][25]. The device used by the authors was the SphygmoCor, which enables PP to be measured non-invasively at the radial site.…”

“…The BP+ device incorporates an oscillometric BP module, which complies with the Association for the Advancement of Medical Instrumentation (AAMI SP10) requirements and receives an A/A rating from the British Hypertension Society evaluation protocol. 31 Following 20 minutes of undisturbed supine rest, oscillometric pressure waveforms were recorded in patients by a single operator on the left upper arm, following standard manufacturer guidelines. 32 Each measurement cycle was %40 seconds, consisting of a brachial BP recording and then a 10-second suprasystolic recording.…”

Background--Atherosclerosis begins during preadolescence and is occurring at an accelerated rate. This acceleration has been linked to poor lifestyle behaviors and subsequent cardiometabolic complications. Although the clustering of cardiometabolic risk factors has been recognized for over 2 decades, previous studies in children have predominantly examined the relationships between atherosclerosis and individual cardiometabolic risk factors or have grouped together preadolescent and adolescent children. Further, no known studies have included glycated hemoglobin or central hemodynamic measures such as central systolic blood pressure and augmentation index.
