Arterial thromboembolism (ATE) is a common and fatal complication of hypertrophic cardiomyopathy(HCM) in cats. Therefore in this study, we evaluated the hypercoagulability (using plasma concentration of D-dimer)in HCM cats with different stage of heart failure and left atrial enlargement and also investigated the any correlationwith echocardiographic indices (including left free wall thickness at diastole, interventricular septal thickness at diastole,LA to Ao ratio, heart failure stage, existence of systolic anterior motion of mitral valve). The median plasma D-dimerconcentration in this study population was 0.51 ± 0.70 (range 0 to 2.50) ug/mL in the control group, 1.47 ± 1.29 (range0.3 to 5.79) ug/mL in the HCM group, 1.48 ± 1.65 (range 0.3 to 5.79) ug/mL in the ISACHC I group, 1.62 ± 0.4(range 1.31 to 2.07) ug/mL in the ISACHC II group, 1.36 ± 0.91 (range 0.3 to 2.31) ug/mL in the ISACHC III group,1.90 ± 1.60 (range 0.3 to 5.79) ug/mL in the cat with LA dilation, 1.72 ± 0.72 (range 0.6 to 2.31) ug/mL in cats withSEC-T, 1.19 ± 0.70 (range 0.3 to 2.31) ug/mL in the cats with SAM, and 1.63 ± 0.80 (range 0.6 to 2.31) ug/mL inthe cats with ATE. Our study found the median and mean concentration of plasma D-dimer was higher in cat withHCM, ATE, SECT and SAM and clearly provides evidence of hypercoagulability in cats with HCM, although theseverity was not correlated to the dilation of LA and the presence of heart failure. This is the first study evaluatingthe hypercoagulability in cats with HCM in Korea.
