- W4312291338 abstract "Pulmonary vascular resistance (PVR) and compliance (C) both significantly contribute to right ventricular (RV) afterload. PVR are most often used as the parameter of RV afterload, despite C has been shown a strong independent predictor of mortality. The two parameters have been showed to be inversely related according to a hyperbolic function, and their relative variations in two consecutive right heart catheterizations are described by the vector lambda (λ=±√((ΔR)<sup>2</sup>+(ΔC)<sup>2</sup>)), which is positive in case of improvement in R (ΔR negative) and otherwise negative (Lankaar et al, EHJ 2008). The potential value of lambda as a combined outcome predictor was tested in 85 consecutive patients with an established diagnosis of PH (classification group I and IV). Lambda was positive in 57 patients (67%). The vector length is related with the variations in cardiac index (R=0.52, p<0.01); also, patients with a positive λ had a significant higher number of clinical low-risk criteria at second catheterization (82% of patients with 3-4 low-risk criteria vs 48% in patients with negative λ, p<0.05), and their mortality rate was significantly lower (8 patients, or 14% vs 11 patients or 39% of patients with negative λ, p<0.01). According to these preliminary data, the vector λ can provide a more comprehensive, reliable outcome predictor in patients with PH." @default.
