Serum cardiac troponin I concentrations in clinically normal and Dirofilaria immitis infected Korean Jindo dogs / 대한수의학회지

This study was conducted to determine the serum cardiac troponin I (cTnI) concentrations in clinically normal (uninfected) Korean Jindo dogs and those infected with Dirofilaria (D.) immitis. Forty Korean Jindo dogs (22 females, 18 males) were obtained from two kennels in the Boryeong area of Chungnam Province and the Daejeon area, Korea. Significantly higher cTnI concentrations were observed in D. immitis-infected dogs than clinically normal dogs. cTnI testing in addition to thoracic radiography, echocardiography, and electrocardiography shows promise as an additional method for diagnosis of heartworm infection.
