Diastolic Dysfunction and Heart Failure With Preserved Ejection Fraction: Understanding Mechanisms by Using Noninvasive Methods

Masaru Obokata, Yogesh N.V. Reddy, and Barry A. Borlaug J Am Coll Cardiol Img. 2020 Jan, 13 (1_Part_2) 245–257 Abstract Research in the last decade has substantially advanced our understanding of the pathophysiology of heart failure with preserved ejection fraction (HFpEF). However, treatment options remain limited as clinical trials have largely failed to identify effective therapies. PartContinue reading “Diastolic Dysfunction and Heart Failure With Preserved Ejection Fraction: Understanding Mechanisms by Using Noninvasive Methods”
