Which Measurement of Blood Pressure Is More Associated With Albuminuria in Patients With Type 2 Diabetes: Central Blood Pressure or Peripheral Blood Pressure?

Comparison of brachial-ankle pulse wave velocity and carotid-femoral pulse wave velocity in association with albuminuria in a community of Beijing: a cross-sectional study

This study was performed to investigate and compare the association of albuminuria with the brachial-ankle pulse wave velocity (baPWV) and carotid-femoral pulse wave velocity (cfPWV) in a community-based population in Beijing. Subjects were enrolled from a follow-up survey conducted in 2018 from an atherosclerosis cohort in Shijingshan district, Beijing, China. The baPWV and cfPWV were measured using a BP-203 RPE III arteriosclerosis detection device and PulsePen, respectively. Albuminuria was defined as a urinary albumin-creatinine ratio of ≥30 mg/g. A multivariate logistic regression model was used to evaluate the impacts of different PWV measurements on the prevalence of albuminuria. In total, 5605 subjects were included in the analyses. Their mean age was 62.22 ± 7.55 years, and the prevalence of albuminuria was 8.22%. In the multivariate logistic regression model adjusted for potential covariates, both baPWV (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.03-1.10; P < 0.001) and cfPWV (OR, 1.07; 95% CI, 1.01-1.14; P = 0.018) were significantly associated with albuminuria. Furthermore, when baPWV and cfPWV were entered into the logistic regression model simultaneously, only baPWV was significantly associated with albuminuria using either continuous value (OR, 1.05; 95% CI, 1.01-1.10; P = 0.007) or classified into quartiles (highest vs. lowest value group: OR, 1.55; 95% CI, 1.01-2.37; P for trend = 0.019). Both cfPWV and baPWV were positively associated with albuminuria, while baPWV had a stronger relationship than cfPWV. Thus, baPWV measurement could be considered for the purpose of community health screening.

Central blood pressure for the management of hypertension: Is it a practical clinical tool in current practice?

Since noninvasive central blood pressure (BP) measuring devices are readily available, central BP has gained growing attention regarding its clinical application in the management of hypertension. The disagreement between central and peripheral BP has long been recognized. Some previous studies showed that noninvasive central BP may be better than the conventional brachial BP in association with target organ damages and long-term cardiovascular outcomes. Recent studies further suggest that the central BP strategy for confirming a diagnosis of hypertension may be more cost-effective than the conventional strategy, and guidance of hypertension management with central BP may result in less use of medications to achieve BP control. Despite the use of central BP being promising, more randomized controlled studies comparing central BP-guided therapeutic strategies with conventional care for cardiovascular events reduction are required because noninvasive central and brachial BP measures are conveniently available. In this brief review, the rationale supporting the utility of central BP in clinical practice and relating challenges are summarized.

BP Measurement Techniques: What They Mean for Patients with Kidney Disease

Patients with CKD typically have hypertension. Manual BP measurement in the office setting was used to define hypertension, establish eligibility, and assess BP targets in the epidemiologic studies and early randomized, controlled trials that inform current management of hypertension. Use of automated oscillometric devices has largely replaced manual BP measurement in the office and clinical trials. These newer devices may reduce the white coat effect and facilitate guideline-adherent measurement protocols. Obtaining BP measurements outside of the office with home and ambulatory BP monitoring is now more common. Out of office BPs are especially important in patients with CKD, because reduced GFR and proteinuria are associated with masked hypertension (normal office BP and elevated BP outside of the office), elevated nighttime BP, and abnormal diurnal variation in BP, all of which are associated with higher risk for target organ damage and adverse outcomes. Also, it is now feasible to routinely measure central BP and central hemodynamics. These measures are of greater importance to patients with CKD given the higher prevalence of increased sympathetic tone, arteriosclerosis, and inflammation as well as impaired sodium excretion and endothelial dysfunction, which lead to alterations in central BPs in this population. In this review, we describe various BP measurement techniques and how they apply to the care of patients with CKD.
