Study objective: To identify Change in Systemic Arterial Pulsatitlity index (∆SAPi) as a novel hemodynamic marker associated with outcomes in heart failure (HF). Design: The ESCAPE trial was a randomized controlled trial. Setting: The ESCAPE trial was conducted at 26 sites. Participants: 134 patients were analyzed (mean age 56.8 ± 13.4 years, 29 % female). Interventions: We evaluated the change in SAPi, (systemic pulse pressure/pulmonary artery wedge pressure) obtained at baseline and at the final hemodynamic measurement in the ESCAPE trial. Main outcome measures: Change in SAPi, (∆SAPi), was analyzed for the primary outcomes of death, heart transplant, left ventricular assist device (DTxLVAD) or hospitalization, (DTxLVADHF) and secondary outcome of DTxLVAD using Cox proportional hazards regression. Results: Median change in SAPi was 0.81 (IQR 0.20–1.68). ∆SAPi in uppermost quartile was associated with reductions in DTxLVADHF (HR 0.55 [95 % CI 0.32, 0.93]). ∆SAPi in the uppermost and lowermost quartiles combined was similarly associated with significant reductions in DTxLVADHF (HR 0.62 [95 % CI 0.41, 0.94]). ∆SAPi higher than 1.17 was associated with improved DTxLVADHF. ∆SAPi was also associated with troponin levels at discharge (regression coefficient p = 0.001) and trended with 6-minute walk at discharge (Spearman correlation r = 0.179, p = 0.058). Conclusion: ∆SAPi was strongly associated with improved HF clinical profile and adverse outcomes. These findings support further exploration of ∆ SAPi in the risk stratification of HF. |
