TNNI3 and heart disorder: The median cTnI concentration in AP dogs (0.384 ng/mL, range: 0.041‐2.966 ng/mL) was greater than that of dogs classified as having mild‐to‐moderate cardiac disease (median: 0.113 ng/mL, range: 0.026‐0.291 ng/mL) and just below those classified as having severe cardiac disease requiring immediate intervention (median: 0.394 ng/mL, range: 0.155‐4246 ng/mL) in a recent study.33
