Using an in-office passive leg raise to identify older adults with suboptimal blood pressure control

Summary: | Passive leg raise (PLR) is a simple, dynamic maneuver that has been used to increase preload to the heart. We hypothesize that PLR may offer a new and efficient office-based tool for assessing blood pressure (BP) control in older adults.
One hundred and three veterans (≥60 years old) without known cardiovascular disease and varying degrees of blood pressure control were included in this cross-sectional cohort study. Twenty-four hour ambulatory BP monitoring identified Veterans with optimal and suboptimal BP control (≥125/75 mmHg). Bioimpedance electrodes (Baxter Medical, Deerfield, Illinois, USA) and brachial BP were used to calculate hemodynamic parameter changes across PLR states [pre-PLR, active PLR (3 min), and post-PLR]. Multiple linear regression was used to assess associations between BP control status with changes in hemodynamic parameters between PLR states.
The 24-h ambulatory BP monitoring identified 43 (42%) older Veterans with optimal BP control (mean age of 70.5 ± 7.0 years) and 55 (54%) with suboptimal BP (mean age of 71.3 ± 8.7 years). Veterans with suboptimal BP control had significantly reduced change in total peripheral resistance (ΔTPR) (7.0 ± 156.0 vs. 127.3 ± 145.6 dynes s/cm5; P = 0.002) following PLR compared with Veterans with optimal BP control. Suboptimal BP control (β = -0.35, P = 0.004) had a significant association with reduced ΔTPR, even after adjusting for demographic variables.
Measuring PLR-induced hemodynamic changes in the office setting may represent an alternative way to identify older adults with suboptimal BP control when 24-h ambulatory BP monitoring is not available. |
