1/6 While I’m on the “EF in amyloid” topic, to clarify: not useless but more important numbers: GLS ( LV and RV) , stroke volume index, MCF (not routinely calculated), cardiac index, RVSP. Non echo: cardiac biomarkers, GFR, 6 min walk, peak VO2, diuretic dose, # hospitalizations 2/6 EF: I tell patients: I care if it’s roughly <25, 25-40, or >40%. Small fluctuations don’t matter much and are not usually a true change in cardiac function even if they sound like it (“But doc, my EF went from 29 to 37%!). I spend a LOT of time explaining limitations of EF.
