Association between HFpEF and Impaired Left Heart strain in Hypertensive Heart Disease: Evaluation by Cardiac MRI Feature Tracking

The application value of left atrial and left ventricular strain parameters to heart failure with preserved left ventricular ejection fraction in hypertensive heart disease was evaluated by cardiac magnetic resonance feature tracking technology. We found that the left atrial function, strain, and left ventricular strain parameters were impaired to varying degrees in the HFpEF-HHD group, and the left atrial ejection fraction was significantly correlated with some feature parameters of left atrial and left ventricular strain. However, NT-proBNP is only significantly correlated with LAεa. In the identification of the HFpEF-HHD population, the LASRe parameter has shown optimal diagnostic value.
