Article Abstract
Objective: This study was designed to identify why the central blood pressure (cSBP) values obtained using the catheter method tend to be higher than brachial systolic blood pressure (bSBP) values obtained using the cuff method.
Methods: This study enrolled 20 patients who underwent coronary angiography (CAG) (mean age, 68.9 years; 13 men). Using the catheter method, a pressure guide wire was inserted via the radial artery at the time of CAG to measure the cSBP. The guide wire was then removed and the bSBP was obtained using two methods (the pressure guide wire method and the cuff method). The cSBP obtained with the catheter and the bSBP obtained with the cuff were compared, as were the bSBP obtained with the cuff and the bSBP obtained with the catheter.
Results: The cSBP obtained with the catheter was 4.6 mmHg higher than the bSBP obtained with the cuff. The bSBP obtained with the cuff was 8.3 mmHg lower than the bSBP obtained with the catheter. The cSBP obtained with the catheter was 1.7 mmHg lower than the bSBP obtained with the catheter.
Conclusion: In elderly patients with evident or suspected coronary heart disease, the finding of a higher cSBP measured using the catheter method than the bSBP obtained using the cuff method is attributable to bSBP underestimation (by 8.3 mmHg) using the cuff method compared to the bSBP directly obtained using the catheter method.

Inaccuracy of brachial blood pressure and its potential impact on treatment and aortic blood pressure estimation.

Objective: Although brachial cuff SBP is universally used to guide hypertension management, it can differ significantly from intraarterial SBP. We examine the potential impacts of cuff-to-intraarterial brachial SBP (bSBP) mismatch on hypertension treatment and accuracy towards central SBP.
Methods: In 303 individuals, cuff bSBP (CUFF-bSBP) and central SBP were measured using a Mobil-o-Graph simultaneously to intraarterial bSBP (IA-bSBP) and aortic SBP.

Purpose: To examine the acute influence of caffeine on post-exercise central blood pressures, arterial stiffness, and wave reflection properties.
Methods: In a double-blind randomized placebo-controlled crossover study design, ten middle-aged males (55 ± 5 year) completed two exercise trials after ingestion of caffeine (400 mg) or placebo. Measurements were taken before and 30 min post-ingestion via cuff-based pulse wave analysis (PWA) and carotid-femoral pulse wave velocity (PWV).

Unlabelled: The influence of time, manifested in the oscillatory nature of physiology, has been documented in many processes. Within blood flow restriction literature, the restrictive stimulus is often applied based on a single arterial occlusion measurement, which is closely related to brachial systolic blood pressure (bSBP). Considering the oscillatory nature of bSBP, it is likely that time also influences arterial occlusion measurements.

Purpose: The main aim of this study was to examine differences in upper arm arterial occlusion pressure (AOP) between three different cuff widths and how individual characteristics influence this. Additional aims of the study were to investigate differences in AOP due to sex and race and to create regression equations that estimate AOP for each cuff width.
Methods: Two hundred and forty nine participants (males n = 102; females n = 147) visited the laboratory once for measurement of arm length, arm circumference, and resting brachial systolic (bSBP) and diastolic blood pressure (bDBP).
