BACKGROUND: Passive leg lifting (PLL) may serve as a simple alternative to simulate exercise stress.
METHODS AND RESULTS: We evaluated 33 patients with PH who underwent PLL-RHC and exercise right heart catheterization (RHC); 25 patients were classified as having PLL-induced PH (LIPH), demonstrating significant increases in mean pulmonary arterial pressure (mPAP) and mPAP-cardiac output slopes. Strong correlations were observed between PLL-RHC and exercise RHC measurements.
CONCLUSIONS: PLL-RHC may represent a simple method for detecting EIPH.
