Troponin I as a biomarker of cardiac injury in sepsis, and other hematological parameters in female dogs with pyometra were evaluated. The groups did not differ in the assessment of serum cardiac troponin I. The total amount of leukocytes (mm3) and percentage of band cells was significantly higher in the sepsis group (23,221.74±16,848.80mm3 and 5.91±10.18%) compared to the non-sepsis group (14,492.86±6,828.26mm3 and 1.93±1.64%) and the control group (10,320.00±3,999.02mm3 and 1.65±2.05% respectively). There were significant differences in serum concentrations of C-reactive protein (mg / dL) in the sepsis group (19.57±41.69md / dL) compared to the non-sepsis group (10.29±12.02mg / dL) and control group (3.60±3.53mg / dL). In the evaluation of serum lactate concentration, there was a significant difference between dogs with pyometra and healthy dogs, but there was no significant difference between the sepsis and non-sepsis groups. The results of this study indicate that troponin I could not be considered an early biomarker of myocardial injury in cases of dogs with pyometra, because the results of the measurements were similar between groups, inferring that there may not have been an cardiomyocytes injury at this stage. C-reactive protein and lactate are potential markers for systemic inflammation, as demonstrated by significantly higher serum concentrations in dogs with pyometra.
