Large animal models for diastolic dysfunction and diastolic heart failure-a review of the literature.
Diastolic heart failure (DHF) or heart failure with preserved systolic left ventricular function is estimated to account for approximately 40% of heart failure cases. Medical treatment of patients with DHF is limited and mainly empirical. Device-based therapy has an increasing role in the treatment of systolic heart failure and may have a future role in the treatment of DHF patients. Diastolic dysfunction and DHF are associated with anatomical and physiological characteristics, which need to be modeled in large animals in order to allow evaluation of device-based therapies, prior to clinical studies. In this article, we will review the large animal models for diastolic dysfunction and heart failure.
