As shown in FigureC, compared with the S‐HFpEF group with recent ADHF admissions the AD‐HFpEF cohort had significantly higher levels of IL‐6 (4.14 pg/mL versus 2.00 pg/mL, P<0.001), hs‐CRP (11.90 mg/dL versus 5.36 mg/dL, P<0.001) and PTX3 (3.08 ng/mL versus 1.46 ng/mL, P<0.001), but there was no statistically significant difference in TNF‐α (11.54 pg/mL versus 9.92 pg/mL, P=0.202). Here, PTX3 is linked to Alzheimer disease.
