Background: N-terminal pro B-type natriuretic peptide (NT-proBNP) and cardiac troponin-I (cTnI) are biomarkers commonly evaluated in cats with suspected heart disease. Many cats with hypertrophic cardiomyopathy (HCM) have systolic anterior motion of the mitral valve (SAM), but its influence on circulating NT-proBNP or cTnI concentrations is currently unknown.
Hypothesis/objectives: Cats with HCM and SAM (HCM ) have higher NT-proBNP and cTnI concentrations than do cats with HCM but without SAM (HCM ).
