Abstract
The objectives of this study were to investigate the usefulness of mitral flow propagation velocity (Vp) in cats by evaluating the effect of the flow pattern summation and evaluation of Vp variables in cats with hypertrophic cardiomyopathy (HCM). Healthy cats were categorized into summation (Sum) and separation (Sepa) groups to evaluate the effects of the flow pattern summation on Vp. Cats with HCM were categorized into HCM left atrial (LA) (-), LA (+), and LA (++) groups according to the degree of LA enlargement to investigate the feasibility of Vp. There were no significant differences noted in Vp between the Sum and Sepa groups and no significant correlation between Vp and heart rate. Decline of Vp was associated with the degree of LA enlargement. Mitral flow propagation velocity appeared to be clinically feasible in cats and could possibly be useful in the detection of diastolic dysfunctions in cats with HCM.
摘要
本研究旨在通过评估肥厚型心肌病（HCM）猫的血流模式总和和 Vp 变量的评估，探讨二尖瓣血流传播速度（Vp）在猫中的应用价值。将健康猫分为总和（Sum）和分离（Sepa）组，以评估血流模式总和对 Vp 的影响。根据左心房（LA）增大程度，将 HCM 猫分为 HCM 左心房（LA）（-）、LA（+）和 LA（++）组，以探讨 Vp 的可行性。Sum 组和 Sepa 组之间的 Vp 没有显著差异，Vp 与心率之间也没有显著相关性。Vp 的下降与 LA 增大的程度相关。二尖瓣血流传播速度在猫中具有临床可行性，可能对检测 HCM 猫的舒张功能障碍有用。
