Validation of inflationary noninvasive blood pressure monitoring in the emergency room.
The aim of this study was to compare the values of a noninvasive blood pressure (NIBP) measurement during cuff inflation (inflationary NIBP) and deflationary NIBP measurements and to verify whether inflationary NIBP is equivalent to conventional deflationary NIBP and is acceptable for clinical use in the emergency room (ER). ⋯ Inflationary NIBP measurements have a reasonable accuracy and a sufficient rapidity, compared with deflationary NIBP measurements, in ER patients.

Comparative StudyFeasibility of oscillometric aortic pressure and stiffness assessment using the VaSera VS-1500: comparison with a common tonometric method.
A number of operator-independent oscillometric devices to measure hemodynamics and arterial stiffness became available recently, but some and in particular VaSera VS-1500 do not provide estimates of aortic pressures and aortic pulse wave velocity (aPWV). The aim of this work was the retrospective application of the ARCSolver algorithm to pulse wave signals acquired with the VaSera VS-1500 device to estimate central systolic blood pressure (cSBP) and aPWV. ⋯ These results show that the combined application of the ARCSolver method with the VaSera VS-1500 device is feasible and the results are comparable with tonometric determination of cSBP and aPWV. This successful application of the ARCSolver may potentially help to improve cardiovascular risk stratification and prevention at an early stage in a community setting.

Review Meta AnalysisPrevalence of simultaneously measured interarm systolic blood pressure difference and its clinical and demographic predictors: a systemic review and meta-analysis.
Prevalence of interarm systolic blood pressure difference and clinical and demographic characteristics associated with interarm systolic blood pressure difference (IASBPD) have been a matter of debate. We aimed to ascertain the prevalence of IASBPD and clinical and demographic characteristics associated with it. We searched PubMed, EMBASE, and CINAHL, Ovid and Cochrane Library, and Google Scholar. ⋯ After BMI, hypertension and dyslipidemia had strongest association with IASBPD, but results were not statistically significant. IASBPD is relatively prevalent, but prevalence is lower than that previously reported. Prevalence is higher when blood pressure is measured in hospital setting compared with outpatient and community setting.

Randomized Controlled Trial Comparative Study Clinical TrialNoninvasive assessment of hemodynamics: a comparative analysis of fingertip pulse contour analysis and impedance cardiography.
Systemic hemodynamic assessment is useful for characterizing the underlying physiology of hypertension, selecting individualized treatment approaches, and understanding the underlying mechanisms of action of interventions. Invasive methods are not suitable for routine clinic or research use, and noninvasive methods such as impedance cardiography have technical and practical limitations. Fingertip pulse contour analysis using the Nexfin device is a novel alternative to noninvasive assessment of blood pressure and hemodynamics. Although both impedance cardiography and the Nexfin have been validated against invasive methods, the extent to which they are correlated with each other is unknown. This study is a comparative analysis of data simultaneously obtained by impedance cardiography and using the Nexfin device. ⋯ We conclude that Nexfin is not an appropriate alternative to impedance cardiography for measurement of underlying hemodynamics in psychophysiological research, but may be useful for beat-to-beat monitoring of blood pressure and heart rate variability.

Clinical TrialRole of catecholamines in acute hypertensive response: subarachnoid hemorrhage versus spontaneous intracerebral hemorrhage.
Acute hypertensive response, defined as systolic blood pressure (SBP) 140 mmHg or more within 24 h of onset, is frequently observed in hemorrhagic stroke patients. Although catecholamine surge is pivotal in its pathogenesis, few studies have evaluated the relationship between admission SBP and plasma catecholamine levels. ⋯ An acute hypertensive response may be more complex, multifactorial, and less catecholamine dependent in SICH patients compared with SAH patients.
