This study evaluated the levels of cardiac biomarkers in dogs with either pulmonic stenosis or aortic stenosis and the correlation between biomarkers and the severity of stenosis assessed by the echocardiography. To achieve this study goal, 38 dogs (10 healthy control dogs, 15 dogs with pulmonic stenosis and 13 dogs with aortic stenosis) were examined. The jet velocity and pressure gradient in this study population were measured by echocardiographic estimation, after which the study group was subdivided by the severity of stenosis. The plasma cardiac troponin I (cTnI) and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured in this study group. The median concentrations of cTnI and NT-proBNP of the disease group were significantly higher than those of the control group, and these increased gradually as stenosis worsened. The severity of stenosis and the concentrations of cTnI and NTporBNP were also found to be significantly correlated. Finally, the plasma cTnI and NT-proBNP tests were found to beneficial for differentiating clinical patients, predicting the progression of disease, and monitoring the outcome of interventional therapy for stenosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
