Preload recruitable stroke work (SW) (PRSW) as SBMw in patients with nonischemic dilated cardiomyopathy. Comparison of SBMw and SW/EDV before (A) and after adding mineralocorticoid receptor antagonist (MRA) (B). Comparison of SBMw and SW/EDV adjusted for peripheral vascular elastance (Ea) (TCP) before (C) and after adding MRA (D). PRSW increased markedly after adding MRA (Panel A vs. B). Increased slope of the [(SW/EDV)/Ea]‐SBMw relation after MRA demonstrated both increase in PRSW and sensitivity to Ea (Panel B vs. D). Please refer to the text for details. EDV, end diastolic volume; SBM, single‐beat method.
