Summary: The study shows that measures of aortic stiffness and pulsatile hemodynamics are independently associated with future thoracic aortic aneurysm growth, providing novel insights into disease activity. These findings highlight the role of central hemodynamic assessment in tailoring new risk assessment and therapeutic strategies for patients with thoracic aortic aneurysm.

Summary: In this non-invasive study, the estimation of central systolic blood pressure (cSBP) using the DCBP formula was compared with the estimation using radial tonometry. The results showed a linear relationship between cSBP estimated by DCBP and cSBP estimated by radial tonometry, and the DCBP method exhibited good sensitivity and specificity in discriminating high blood pressure threshold.

Summary: Central systolic blood pressure (cSBP) is more closely associated with hypertension-mediated organ damage and prognosis than brachial systolic blood pressure. This study investigated the 24-hour profiles of brachial and central SBP in untreated adults, providing reference values and analyzing daytime-nighttime variability. The findings have potential implications for refining hypertension diagnosis and management.

Summary: Continuous finger-cuff arterial pressure monitoring helps reduce hypotension within 15 min after starting induction of anesthesia and during noncardiac surgery compared to intermittent oscillometric arterial pressure monitoring.

Summary: This study found that the width of oscillometric waveform envelopes significantly increased with higher blood pressure and aging. The envelopes in high-pressure region were larger than in low-pressure region in normal and hypertensive categories, as well as in elderly patients aged over 60 years, and the envelope width ratios between them increased with increased BP and aging.

Summary: This study aimed to determine the impact of the differences between cuff and invasive systolic blood pressure (SBP) on cardiovascular disease (CVD) events and related costs. The study found that cuff SBP underestimation can result in missed CVD events and significant increases in health costs.

Summary: In older individuals, cuff blood pressure fails to correctly identify isolated systolic hypertension compared to invasive blood pressure, indicating a need for improvement in cuff blood pressure measurements.

Summary: This study aimed to compare the agreement between cuff-based and invasively measured SBP amplification. The results showed differences between the two methods, with cuff-based estimates demonstrating systematic bias and less individual variability.

Summary: This study aimed to evaluate the associations between non-invasive central aortic and peripheral blood pressure and hypertension-mediated organ damage (HMOD) and atherosclerotic cardiovascular disease (ASCVD) risk. The results showed that blood pressure obtained by 24-hour ambulatory blood pressure monitoring (ABPM) was better correlated with HMOD than office blood pressure. Additionally, 24-hour central blood pressure had a superior prognostic value for the 10-year ASCVD risk compared to 24-hour peripheral blood pressure.

Summary: This study investigated the relationship between cardiovascular risk and central and brachial systolic pressure and proposed thresholds to differentiate hypertension from normal blood pressure. Regardless of brachial blood pressure status, central hypertension was associated with increased cardiovascular and cerebrovascular risk, highlighting the importance of controlling central hypertension.

Summary: Non-invasive blood pressure measurements often underestimate systolic blood pressure and overestimate diastolic blood pressure. The study found that Korotkoff sounds accurately detect the onset of blood flow and closely coincide with diastolic blood pressure.

Summary: Automated cuff measured blood pressure is the global standard for diagnosing hypertension, but concerns exist regarding its accuracy. This study aimed to determine the relationship between individual variability in systolic blood pressure amplification and the accuracy of cuff blood pressure. It was found that cuff blood pressure significantly underestimated brachial blood pressure and that systolic blood pressure amplification correlated with cuff blood pressure accuracy.

Summary: This study evaluated the clinical significance of new non-invasive vascular indices through repeated measurements. The results showed that while diastolic blood pressure and arterial velocity pulse index did not significantly change, systolic blood pressure and arterial pressure volume index decreased significantly according to the measurement orders. Furthermore, there was a significant correlation between the changes in systolic blood pressure and arterial pressure volume index.

Summary: The study found that cSBP could be reliably estimated using only MBP and DBP, provided that blood pressure measurement errors are minimized. This method may have implications for assessing cardiovascular risk associated with cSBP on large BP databases, warranting further research.

Summary: This study aims to improve the understanding of arm volume pulsations in oscillometric signals and identify factors affecting the transfer function from arm volume to cuff pressure oscillations. Experimental and numerical modeling results show that typical cuffs exhibit complex behavior, indicating the need for hardware improvement in order to enhance blood pressure measurement accuracy.
