Cardiomyopathy, arterial thrombembolism and hypercoagulability in cats
Arterial thromboembolism (ATE) is a common complication of feline cardiomyopathy; however, the pathogenesis of ATE is unknown. Is there perhaps a systemic activation of the coagulation cascade (hypercoagulability) in affected cats, and endothelial injury promotes ATE? An interesting hypothesis...


Healthy cats (n = 30) and 3 groups of cardiomyopathic cats: Group (1) left atrial enlargement only (LAE [n = 11]), ie, left atrial to aortic ratio >1.4; Group (2) LAE with spontaneous echocardiographic contrast, atrial thrombi or both (SEC-T [n = 16]); and Group (3) acute ATE with LAE (n = 16).

Methods: Hypercoagulability was defined by 2 or more laboratory abnormalities reflecting coagulation factor excess (high fibrinogen concentration or Factor VIII coagulant activity), inhibitor deficiency (low antithrombin activity), or thrombin generation (high thrombin-antithrombin complex [TAT] and d-dimer concentrations).

High von Willebrand factor antigen concentration (vWF : Ag) was considered a marker of endothelial injury. Data were analyzed using nonparametric statistics.

Results: The 3 groups of cats with cardiac disease had higher median fibrinogen concentrations than did the healthy cats.

Criteria of hypercoagulability were found exclusively in cats with SEC-T (50%) and ATE (56%).

Hypercoagulability was not associated with left atrial size or congestive heart failure (CHF). ATE cats had significantly higher median vWF : Ag concentration than did the other groups.

Conclusions and Clinical Importance: Systemic hypercoagulability is evident in many cardiomyopathic cats, often without concurrent CHF or overt ATE.

Hypercoagulabilty may represent a risk factor for ATE.

High vWF : Ag in ATE cats was attributed to downstream endothelial injury from the occlusive thrombus.

Concentrations of a marker of type I collagen metabolism in ragdolls with HCMmembers
HCM (hypertrophic cardiomyopathy) is a common and life-threatening disease in many cat breeds, and the diagnosis especially in an early stage is extremely difficult. Human carriers of hypertrophic cardiomyopathy associated sarcomeric mutations have abnormal collagen metabolism before overt left ventricular hypertrophy is detectable. This fascinating new study investigated whether differences in collagen biomarkers were present in blood samples of ragdoll cats positive for the MYBPC3:R820W mutation compared with negative controls.
