Cardiac Magnetic Resonance Assessment for Heart Failure With Preserved Ejection Fraction

The University of Hong Kong172 enrolled

Overview

This is a prospective study that aims to define the utility of cardiac magnetic resonance feature tracking (CMR-FT) as a non-invasive quantification tool to assess diastolic functionality in patients with Heart Failure with preserved ejection fraction.

Despite the increasing prevalence and poor prognosis of HFpEF worldwide, it is facing diagnostic challenges due to its non-specific clinical manifestations. Currently, echocardiography serves as the main diagnostic tool, but alternatives are limited to less preferred invasive procedures in most clinical situations. It is therefore proposed to investigate HFpEF using cardiovascular magnetic resonance imaging (CMR), as an alternative non-invasive diagnostic tool which carries lower risk than invasive procedures. The study aims to: (1) access the utility of CMR-FT as a new indicator to diagnose diastolic dysfunction by differentiating HFpEF patients from non-HFpEF patient and normal volunteers. (2) Compare accuracy of CMR-FT to CMR tagging and phase contrast imaging.
