Abstract
OBJECTIVE
To determine whether a normal cardiac troponin I (cTnI) concentration and normal ECG on entry rule out the development of a clinically significant cardiac arrhythmia (CSCA, defined as an arrhythmia requiring anti-arrhythmic treatment) in dogs that have sustained blunt trauma.
DESIGN
Prospective, observational study. Client-owned dogs were enrolled between January 2015 and November 2016.
SETTING
University teaching hospital.
ANIMALS
Forty-seven client-owned dogs with a history of witnessed or suspected blunt trauma within 24 hours prior to presentation to the hospital.
INTERVENTIONS
On admission to the emergency service, dogs had a standard 3-lead ECG and cTnI concentration (using a veterinary point-of-care device*) performed. Animal Trauma Triage (ATT) scores, Modified Glasgow Coma Scale (MGCS), and the details regarding the nature and timing of the injury were recorded. The patients were monitored in the ICU for a minimum of 24 hours on continuous ECG telemetry. Cardiac rhythm was monitored every hour, and any abnormalities were noted. The need for anti-arrhythmic therapy was recorded. There were no treatment interventions.
MEASUREMENTS AND MAIN RESULTS
Five of 47 dogs (10.6%) developed a CSCA during hospitalization after sustaining blunt trauma. A normal entry ECG and normal cardiac troponin concentration on entry had a 100% negative predictive value (NPV) for ruling out the development of a CSCA, although a normal cardiac troponin concentration alone also had an NPV of 100%. A normal entry ECG had an NPV of 95.3%. The prognosis for survival to discharge was 89.4% in this study population (42/47 dogs).
CONCLUSIONS
In dogs with blunt trauma, an entry cTnI concentration or a combination of cTnI and ECG on entry may be useful in determining which patients are at a higher risk for the development of CSCA during the first 12 to 24 hours after the trauma.
