“…4 ] or invasive CPET in the upright position) have higher sensitivity than fluid load and passive leg raising to detect HFpEF 12 100 and may provide additional pathophysiological information on exercise limitation and peculiar hemodynamic phenotypes. 6 32 103 104 Despite quite broad heterogeneity in methodology (supine vs. upright exercise; direct Fick vs. thermodilution CO), ways of pressure measurement (end-expiratory vs. respiratory-averaged; end-diastolic PAWP vs. PAWP averaged over the cardiac cycle), and interpretation of invasive exercise hemodynamic results, 62 it seems reasonable to accept, as indicative of HFpEF, an end-expiratory mean PAWP ≥25 mm Hg at peak exercise in the supine position 12 ( Fig. 4 ; which should roughly correspond to a respiratory-averaged PAWP >20 mm Hg in the supine position 13 and to an end-expiratory mean PAWP >20 mm Hg in the upright position 105 ) and/or a PAWP/CO slope >2 mm Hg/L/min, this latter irrespective of body position.…”

“…Zur Behandlung ausgewählter Fälle der HFpEF und zur Entlastung des linken Herzens unter der Annahme einer Senkung des LA-Druckes wurde die Implantation interatrialer Shunt-Devices untersucht 61 , die langfristigen Auswirkungen auf den pulmonalen Kreislauf sind jedoch bisher unbekannt. Die REDUCE-LAP-HF-II-Studie konnte nach der Platzierung eines interatrialen Shunt-Devices in einer Kohorte von HFpEF/HFmrEF-Patient*innen mit einer LVEF ≥ 40 % keine Reduktion von Herzinsuffizienzereignissen nachweisen, es zeigte sich hingegen ein schlechterer Verlauf bei Vorliegen einer latenten pulmonalvaskulären Erkrankung; diese wurde als ein PVR ≥ 1,74 WU unter Belastung definiert 62 63 . Ein anhaltender Anstieg der pulmonalen Durchblutung könnte sich zudem negativ auswirken, da er bei Patient*innen mit vorbestehender PH ein vaskuläres Remodelling auslösen kann.…”
