Plain-English summary
A group of dogs undergoing heart procedures, like balloon valvuloplasty and pacemaker implantation, had their blood tested for a protein called cardiac troponin I (cTnI) to check for heart damage. The tests showed that cTnI levels increased shortly after these procedures but returned to normal within a few days. Interestingly, dogs that had longer procedures showed higher cTnI levels, indicating a potential risk for heart injury. However, the increase in cTnI didn't seem to affect their short-term recovery.

Abstract
OBJECTIVE: To determine changes in cardiac troponin I concentration (cTnI) associated with cardiovascular catheterization in dogs. ANIMALS, MATERIALS AND METHODS: cTnI was measured after transarterial coil embolization of patent ductus arteriosus (PDA), balloon valvuloplasty (BV), and pacemaker implantation (PACE). Dogs undergoing ovariohysterectomy (OHE) were used as a control, with 15 animals in each group. Blood for the cTnI assay was collected at baseline (T0), at 5h (T5), 24h (T24) and 10 days (T240) post-procedure. The effects of age, duration and difficulty of the procedure were evaluated. RESULTS: There was no difference in cTnI concentration at T0 for any of the groups. There was a significant increase in cTnI concentration for BV and PACE, but not PDA at T5 and T24. PACE at T24 and T240 also had higher cTnI than control. Dogs with longer procedure times had significantly higher concentration of cTnI. There was no correlation between the difficulty of the procedure or peri-procedure complications and cTnI. CONCLUSION: cTnI increased during some cardiovascular catheterization procedures, but returned to normal values at 24-240 h. Patients undergoing long catheterization procedures have increased risk for myocardial injury, but this was not related to short-term prognosis.
