Heart failure with preserved ejection fraction（HFpEF）was evaluated by echocardiography commonly. In this study, we try to use Cardiovascular Magnetic Resonance Tissue-Tracking (CMR-TT) to assess left atrial (LA) function in hypertension patients (HP) with left ventricular diastolic dysfunction (LVDD). The results demonstrated that LA myocardial function decreased in HP with LVDD. LA myocardial strain parameters could detect sensitively the myocardial deformation of LVDD in HP. Total strain(εs) parameter was an excellent parameter for diagnose HFpEF and evaluating the degree of LVDD.
