Right ventricular (RV) function is an important predictor of prognosis in patients with heart failure. However, the relationship of the RV free wall longitudinal strain (RV FWS) and the degree of hepatic dysfunction during the acute worsening of heart failure (AWHF) is unknown. We sought to determine associations of RV FWS with laboratory liver function tests and parameters of RV function including tricuspid annular plane systolic excursion (TAPSE), RV fractional area change (RV FAC), maximal tricuspid jet velocity (TR Vmax), RV S′ velocity, and estimated RV systolic pressure (RVSP). A total of 42 AWHF patients from the CATSTAT-HF study were stratified in two groups by the RV FWS median (−16.5%). Patients < RV FWS median had significantly prolonged international normalized ratio (INR; p = 0.002), increased total bilirubin (p < 0.001) and alkaline phosphatase (ALP; p = 0.020), and decreased albumin (p = 0.005) and thrombocytes (p = 0.017) compared to patients > RV FWS median. RV FWS independently correlated to total bilirubin (β = 0.457, p = 0.004), ALP (β = 0.556, p = 0.002), INR (β = 0.392, p = 0.022), albumin (β = −0.437, p = 0.013), and thrombocytes (β = −404, p = 0.038). Similarly, TAPSE, RV FAC, and RV S′ significantly correlated with RV FWS. In conclusion, RV impairment, reflected in reduced RV FWS, is independently associated with a higher degree of hepatic dysfunction among patients with AWHF (CATSTAT-HF ClinicalTrials gov number, NCT03389386).

Abstract
Right ventricular (RV) function is an important predictor of prognosis in patients with heart failure. However, the relationship of the RV free wall longitudinal strain (RV FWS) and the degree of hepatic dysfunction during the acute worsening of heart failure (AWHF) is unknown. We sought to determine associations of RV FWS with laboratory liver function tests and parameters of RV function including tricuspid annular plane systolic excursion (TAPSE), RV fractional area change (RV FAC), maximal tricuspid jet velocity (TR Vmax), RV S′ velocity, and estimated RV systolic pressure (RVSP). A total of 42 AWHF patients from the CATSTAT-HF study were stratified in two groups by the RV FWS median (−16.5%). Patients < RV FWS median had significantly prolonged international normalized ratio (INR; p = 0.002), increased total bilirubin (p < 0.001) and alkaline phosphatase (ALP; p = 0.020), and decreased albumin (p = 0.005) and thrombocytes (p = 0.017) compared to patients > RV FWS median. RV FWS independently correlated to total bilirubin (β = 0.457, p = 0.004), ALP (β = 0.556, p = 0.002), INR (β = 0.392, p = 0.022), albumin (β = −0.437, p = 0.013), and thrombocytes (β = −404, p = 0.038). Similarly, TAPSE, RV FAC, and RV S′ significantly correlated with RV FWS. In conclusion, RV impairment, reflected in reduced RV FWS, is independently associated with a higher degree of hepatic dysfunction among patients with AWHF (CATSTAT-HF ClinicalTrials gov number, NCT03389386).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
