Abstract/OtherAbstract:
|
Mean functional diastolic stiffness, an estimate of the left ventricular resistance to filling during diastole, was measured in 10 normal dogs, 7 dogs with diseases causing volume overload (patent ductus arteriosus and primary mitral valve insufficiency), and 4 dogs with idiopathic congestive cardiomyopathy. It was measured as the increase in pressure during diastole (deltaP), divided by the corresponding increase in volume (deltaV). The pressure was measured at cardiac catheterization, and the volume was derived by a cineangiocardiographic method. There was no increase in diastolic stiffness of the hearts with volume overload compared with the normal hearts, but those with cardiomyopathy had a large increase, although the end-diastolic volumes in cardiomyopathy were generally less than in volume overload. |
