  Overall (N = 134) RTF (N = 40) No FTR (N = 94) Mild FTR (N = 8) Moderate FTR (N = 25) Severe FTR (N = 7) p value for Trend 95% CI range

LVEF, % 46 ± 9.4 37 ± 6.4 50 ± 7.3 43 ± 3.2 37 ± 5.2 28 ± 2.7  < 0.0001 [− 0.02–0.00]
RV FAC, % 28 ± 5.4 22.2 ± 4.3 30 ± 3.6 23 ± 5.0 21 ± 4.4 22 ± 3.8  < 0.0001 [− 0.06–0.01]

  1. Overall and by FTR development grade
  2. R = .395, R2 = .874. The Highest Beta coefficient was observed in LVEF (.396) and RV dysfunction > 2 (.206). No multicollinearity was observed
  3. LVIDD indicates left ventricular internal diameter at end-diastolic phase; LVEF left ventricular ejection fraction; RV FAC, Right ventricular fractional area change; sPAP, systolic pulmonary artery pressure; PHT, Pulmonary Hypertension; MR, mitral regurgitation
