Serial measurement of cardiac troponin I in hospitalised dogs with canine parvoviral enteritis: Association with outcome and canine pancreas-specific lipase concentration.

Abstract

The aim of this study was to serially evaluate serum cardiac troponin I (cTnI) concentrations in dogs with parvoviral enteritis (CPVE), and investigate the association with outcome and serum pancreas-specific lipase (Spec cPL) concentrations. Dogs with CPVE that were hospitalised for at least 5 days were included. cTnI and Spec cPL concentrations were measured on days 1, 3 and 5 of hospitalisation. Twenty-nine dogs (20 survivors, 9 non-survivors) were included. Spec cPL was indicative of pancreatitis (>400 μg/L) on at least one day in 10/29 (34.5%) dogs. Serum median (range) cTnI concentration was higher (P = 0.021) in non-survivors on day 5 [0.032 (0.001-0.395) ng/mL] compared to day 1 [0.012 (0.003-0.196) ng/mL]. Non-survivors had higher (P = 0.014) cTnI concentrations on day 5 [0.032 (0.001-0.395) ng/mL] compared to survivors [0.001 (0.001-0.042) ng/mL], but not at admission or on day 3 (P > 0.05). Serum cTnI concentrations were not significantly different (P = 0.465) between the three Spec cPL groups [group 1 (Spec cPL ≤ 200 μg/L): 0.007 (0.001-0.527) ng/mL; group 2 (Spec cPL: 201-399 μg/L): 0.0045 (0.001-0.196) ng/mL; group 3 (Spec cPL ≥ 400 μg/L): 0.011 (0.001-0.278) ng/mL]. cTnI and Spec cPL concentrations were not significantly correlated (rho = -0.043, P = 0.703). Serial measurement of cTnI had prognostic value in the examined cohort. However, cTnI was not correlated with spec cPL.
