Reference intervals for transthoracic echocardiography in the American Staffordshire Terrier

[摘要] This study reports the echocardiographic reference intervals in the American Staffordshire Terrier (AST). The echocardiographic variables obtained in 57 healthy adult AST were compared with published data from the general canine population and other breeds. In the AST, the left ventricular volumes were lower than values reported in Boxers and Dobermans ( P <0.0001), but higher than in small breeds ( P <0.0001). The left ventricular ejection fraction was higher than Boxers and Dobermans ( P <0.0001), but lower than small breed dogs ( P =0.027). The aortic peak velocity values were similar to Boxers ( P =0.55) but higher than the general canine population ( P <0.0001). The reference intervals presented in this study are clinically useful for an accurate echocardiographic interpretation and screening in the AST.
