Dr. Gregory Lewis and Dr. C. Michael Gibson discuss the IRONMET-HFpEF trial: Single-dose ferric derisomaltose infusion improved the primary endpoint of peak oxygen uptake at 12 weeks in patients with HFpEF and iron deficiency, showing benefits of enhanced functional capacity.

Just published in Circulation- a multi-institution collaborative team effort that leverages insights from invasive cardiopulmonary exercise testing to further understand HFpEF. lnkd.in/eVuF7SkF

To be published in Circulation tomorrow and featured on Circ on the Run today, we describe easily-derived cardio-specific VO2 recovery measures in #HFpEF and their modifiability w/aficamten in oHCM. @CampainJoseph @MGHMedicine @MGHHeartHealth

Our just-published meta-anal of 60 observ studies shows CPET measures (pVO2, VE/VCO2) potently predict outcomes in HCM, complementing trials showing modifiability of CPET measures w/CMIs in oHCM. More to come from #MAPLE-HCM @ #HFSA LBCTs doi.org/10.1161/JAHA.1…
