Invasive aortic pulse pressure is not superior to cuff pulse pressure in cardiovascular risk prediction.

Objective: Aortic pulse pressure (PP) represents the hemodynamic cardiac and cerebral burden more directly than cuff PP. The objective of this study was to investigate whether invasively measured aortic PP confers additional prognostic value beyond cuff PP for cardiovascular events and death. With increasing age, cuff PP progressively underestimates aortic PP.

Influence of Age on Upper Arm Cuff Blood Pressure Measurement.

Blood pressure (BP) is a leading global risk factor. Increasing age is related to changes in cardiovascular physiology that could influence cuff BP measurement, but this has never been examined systematically and was the aim of this study. Cuff BP was compared with invasive aortic BP across decades of age (from 40 to 89 years) using individual-level data from 31 studies (1674 patients undergoing coronary angiography) and 22 different cuff BP devices (19 oscillometric, 1 automated auscultation, 2 mercury sphygmomanometry) from the Invasive Blood Pressure Consortium.

Accuracy of Cuff-Measured Blood Pressure: Systematic Reviews and Meta-Analyses.

Background: Hypertension (HTN) is the single greatest cardiovascular risk factor worldwide. HTN management is usually guided by brachial cuff blood pressure (BP), but questions have been raised regarding accuracy.

Objectives: This comprehensive analysis determined the accuracy of cuff BP and the consequent effect on BP classification compared with intra-arterial BP reference standards.

Evaluation of interarm blood pressure differences using the Microlife WatchBP Office in a clinical setting.

Objective: The aim of this study was to evaluate the usefulness of Microlife WatchBP Office and the effect of increasing the number of measurements in the clinical evaluation of systolic interarm difference (IAD).

Patients And Methods: Office blood pressure was measured simultaneously on both arms in 339 patients (85% diabetic) using the Microlife WatchBP Office, a fully automatic, oscillometric device. The patients included were all scheduled for ambulatory blood pressure measurement at the outpatient clinic of endocrinology at Silkeborg Regional Hospital, Denmark.

Invasively Measured Aortic Systolic Blood Pressure and Office Systolic Blood Pressure in Cardiovascular Risk Assessment: A Prospective Cohort Study.

Aortic systolic blood pressure (BP) represents the hemodynamic cardiac and cerebral burden more directly than office systolic BP. Whether invasively measured aortic systolic BP confers additional prognostic value beyond office BP remains debated. In this study, office systolic BP and invasively measured aortic systolic BP were recorded in 21 908 patients (mean age: 63 years; 58% men; 14% with diabetes mellitus) with stable angina pectoris undergoing elective coronary angiography during January 2001 to December 2012.

Preeclampsia and cardiovascular disease risk assessment - Do arterial stiffness and atherosclerosis uncover increased risk ten years after delivery?

Objectives: Epidemiological studies associate preeclampsia with increased risk of premature cardiovascular disease (CVD) later in life. This study aims to make a comprehensive CVD risk assessment comparing women with previous preeclamptic pregnancies to women with previous normotensive pregnancies 10years after index pregnancy.

Study Design: A nested, matched, observational cohort study.

Targeting nocturnal hypertension in type 2 diabetes mellitus.

Several studies in different populations have suggested that nighttime blood pressure (BP) is a stronger predictor of cardiovascular events than daytime BP. Consequently, treatment strategies to target nighttime BP have come into focus. The aim of the present study was to investigate the effect of change of administration time of antihypertensive drugs.

Assessment of central blood pressure in patients with type 2 diabetes: a comparison between SphygmoCor and invasively measured values.

Background: The SphygmoCor is used for noninvasive assessment of ascending aortic blood pressure (BP). However, the validity of the SphygmoCor transfer function has not been tested in an exclusively type 2 diabetic patient sample. Calibration with systolic (SBP) and diastolic (DBP) brachial BP has previously been associated with substantial imprecision of central BP estimates.

Invasive validation of arteriograph estimates of central blood pressure in patients with type 2 diabetes.

Background: Central blood pressure (BP) has attracted increasing interest because of a potential superiority over brachial BP in predicting cardiovascular morbidity and mortality. Several devices estimating central BP noninvasively are now available. The aim of our study was to determine the validity of the Arteriograph, a brachial cuff-based, oscillometric device, in patients with type 2 diabetes.

Reproducibility of pulse wave analysis and pulse wave velocity in patients with type 2 diabetes.

Aims: Patients with type 2 diabetes have increased arterial stiffness and a high incidence of cardiovascular disease compared with non-diabetics. Arterial stiffness and central waveforms can be assessed by carotid-femoral pulse wave velocity (PWV) and pulse wave analysis (PWA) using the SphygmoCor device. These methods can potentially improve cardiovascular risk stratification in the future.

A plea for consistent reliability in ambulatory blood pressure monitoring: an unusual case of software error in Spacelabs Report Management System 92506.

Objective: Ambulatory blood pressure monitors are subject to extensive validation protocols, but no international guidelines on the software processing the collected raw data exist. Hence, there seems to be little or no control of ambulatory blood pressure monitoring (ABPM) software with respect to errors. In this paper, we wish to point out an important error in Spacelabs Report Management System 92506 software.
