Objective: To evaluate the effects of noncardiac disease on c-terminal brain natriuretic peptide (cBNP) concentrations in dogs.
Design: Prospective observational study.
Setting: Urban university veterinary hospital.
Objective: To determine whether plasma cardiac troponin I (cTnI) concentrations can be used to discriminate cardiac from noncardiac causes of dyspnea in cats.
Design: Prospective, multicenter study.
Animals: Client-owned cats with dyspnea attributable to congestive heart failure (D-CHF; n=31) or to noncardiac causes (D-NCC; n=12).
Measurement of plasma cardiac troponin I concentration ([cTnI]) is a sensitive and specific means for detecting myocardial damage in many mammalian species. Studies have shown that [cTnI] increases rapidly after cardiomyocyte injury. The molecular structure of cTnl is highly conserved across species, and current assays developed for its detection in humans have been validated in many species.
