Measurement of plasma cardiac troponin I concentration by use of a point-of-care analyzer in clinically normal horses and horses with experimentally induced cardiac disease.
Abstract: To compare cardiac troponin I (cTnI) concentrations determined by use of a point-of-care analyzer with values determined by use of a bench-top immunoassay in plasma samples obtained from clinically normal horses with and without experimentally induced cardiac disease, and to establish a reference range for plasma equine cTnI concentration determined by use of the point-of-care analyzer. Methods: 83 clinically normal horses, 6 of which were administered monensin to induce cardiac disease. Methods: A blood sample was collected from each of the 83 clinically normal horses to provide plasma for analysis by use of the point-of-care analyzer; some of the same samples were also analyzed by use of the immunoassay. All 83 samples were used to establish an analyzer-specific reference range for plasma cTnI concentration in clinically normal horses. In 6 horses, blood samples were also collected at various time points after administration of a single dose of monensin (1.0 to 1.5 mg/kg) via nasogastric intubation; plasma cTnI concentration in those samples was assessed by use of both methods. Results: The analyzer-specific reference range for plasma cTnI concentration in clinically normal horses was 0.0 to 0.06 ng/mL. Following monensin treatment in 5 horses, increases in plasma cTnI concentration determined by use of the 2 methods were highly correlated (Pearson correlation, 0.83). Peak analyzer-determined plasma cTnI concentrations in monensin-treated horses ranged from 0.08 to 3.68 ng/mL. Conclusions: In horses with and without experimentally induced cardiac disease, the point-of-care analyzer and bench-top immunoassay provided similar values of plasma cTnI concentration.

Summary
This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.
This research project attempted to establish a reference range for plasma equine cardiac troponin I (cTnI) concentration, using a point-of-care analyzer. The results were compared between healthy horses and those with induced cardiac disease. The results showed a high correlation between the point-of-care analyzer and a standard immunoassay.
Research Methodology
- The study involved 83 clinically healthy horses and 6 horses were administered with monensin to generate artificially induced cardiac disease.
- A blood sample was collected from all 83 horses. These samples were then used in the point-of-care analyzer. Some of these samples were also analyzed with a bench-top immunoassay for comparison.
- All 83 samples were used to create a specific reference range for healthy horse plasma cTnI concentration.
- In 6 horses, blood samples were also collected at various durations after the administration of a single dose of monensin (1.0 to 1.5 mg/kg) via nasogastric intubation. Both the point-of-care analyzer and the immunoassay were used to evaluate the plasma cTnI concentration in these samples.
Research Results
- The specific reference range for healthy horse plasma cTnI concentration, using the point-of-care analyzer, was established to be between 0.0 to 0.06 ng/mL.
- A significant correlation (Pearson correlation, 0.83) was noted between results obtained from the point-of-care analyzer and the immunoassay post administration of monensin.
- The cTnI concentrations in the blood of the horses subjected to monensin treatment ranged from 0.08 to 3.68 ng/mL, as per the point-of-care analyzer.
Research Conclusions
- The research concluded that the point-of-care analyzer and bench-top immunoassay provided similar values of plasma cTnI concentration in horses with both natural and experimentally induced cardiac diseases.
