Plain-English summary
A group of dogs with immune-mediated hemolytic anemia (a condition where the body destroys its own red blood cells) were found to have higher levels of cardiac troponin I, a marker of heart muscle damage, compared to healthy dogs and those with other illnesses. Out of 27 dogs with this anemia, 20 showed elevated troponin levels, indicating potential heart issues. This suggests that dogs suffering from this condition may have underlying heart damage that isn't immediately obvious. Further research is needed to understand the full impact of these findings on their health and treatment options.

Abstract
OBJECTIVES: The assessment of serum cardiac troponin I concentrations in dogs with a range of nonprimary cardiac illnesses has revealed that cardiac myocyte damage is commonplace in many canine diseases. Whilst it is well established that dogs with fatal immune-mediated haemolytic anaemia frequently have cardiac pathology based on post-mortem examinations, there is limited information on the incidence of cardiac myocyte damage in this population of dogs. METHODS: Serum cardiac troponin I concentrations were measured in 11 healthy dogs, 27 dogs with primary haemolytic anaemia and 49 hospitalised dogs without primary cardiac or haematological disorders. RESULTS: Dogs with primary haemolytic anaemia have higher serum concentrations of cardiac troponin I than hospitalised ill dogs (P<0.005) and healthy dogs (P<0.01). Using a cut-off of less than 0.1 ng/mL, 20 of 27 dogs with primary haemolytic anaemia had increased serum cardiac troponin I concentrations, which was a significantly higher proportion compared to the hospitalised ill dogs (P<0.001, 16 out of 49 dogs) and healthy dogs (P<0.05, 3 out of 11 dogs). CLINICAL SIGNIFICANCE: Dogs with primary haemolytic anaemia have a higher incidence of subclinical myocyte damage than healthy dogs or dogs with non-haematological or primary cardiac illnesses. The prognostic significance of increased serum cardiac troponin I concentrations in dogs with primary haemolytic anaemia merits further investigation.
