  1. Left atrial (LA) reservoir strain was the best cardiac magnetic resonance (CMR) strain parameter for diagnosing heart failure with preserved ejection fraction (HFpEF) in clinically suspected patients, with the area under the curve (AUC) of 0.804.
  2. Two other CMR parameters with high diagnostic accuracy were LA area indexed and LA volume indexed, with AUCs of 0.815 and 0.776, respectively.
  3. Tagging, CMR-feature tracking in the left ventricle, and CMR-feature tracking in the right ventricle parameters may be less useful than expected in the diagnosis of HFpEF.
