In chronic HF, reduced ppFVC associated with lower MIP, LVEF, VRes and VO2peak, but no distinct poorer prognosis over 2.2 years of follow-up. Distinctively, FEV1/FVC was associated only with VRes, and, in participants with LVEF ≤50%, FEV1/FVC reduction proportionally worsened prognosis. Therefore, FEV1/FVC and ppFVC add supplementary information regarding HF phenotyping.
