ABSTRACT
BACKGROUND:
This study evaluated the novel index pulmonary arterial proportional pulse pressure (PAPP) in the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) trial. METHODS ANDRESULTS:
Multivariable Cox proportional hazards and logistical regression were used to model 6-month death; death, transplantation, or left ventricular assist device (DTLVAD); and DTLVAD or heart failure rehospitalization (DTLVADHF) with respect to PAPP. Among 175 patients with final hemodynamic data, 15.5% and 33.9%, respectively, died in optimal PAPP (PAPP >0.50) and nonoptimal PAPP (PAPP ≤0.50) groups (P = .008), and PAPP was independently associated with death, DTLVAD, and DTLVADHF (P < .01 for all outcomes). The hypothesized logistic regression model with pulmonary capillary wedge pressure, creatinine, and nonoptimal PAPP had an area under the curve of 0.818 (P < .0001) for death. Furthermore, PAPP as a continuous variable was the most powerful predictor of DTLVADHF (hazard ratio 0.793 per 0.1 increase in PAPP [95% confidence interval 0.659-0.955], chi square 8.80; P = .01) in the Cox model, with no other clinical, laboratory, or hemodynamic parameters significant after adjustment for PAPP.CONCLUSIONS:
PAPP, a novel parameter for right-sided proportional pulse pressure, is an independent and powerful predictor of adverse clinical outcomes in advanced HF. Increased PAPP promises to be a useful therapeutic target in patients with pulmonary arterial pressure assessment.Palabras clave
