射血分数保留型心力衰竭是最具挑战性的临床综合征之一，并逐渐在心力衰竭中占主导地位，其发病率和病死率已与射血分数减少型心力衰竭相当，因此，急需对其临床特点与发病机理等进行系统的研究。然而，目前有关的研究仍无明确且统一的结论。在此，对近几年射血分数保留型心力衰竭的临床特征、病理生理机制、诊断以及治疗方法进行综述，将有助于临床医生对射血分数保留型心力衰竭的诊断与治疗。“,”Heart failure with preserved ejection fraction(HFpEF) is one of the most challenging clinical syndromes ,and has been the main form of heart failure.Importantly,its morbidity and mortality were comparative with the heart failure with reduced ejection fraction ,so HFpEF is greatly in need of the systematic research on its clinical feature ,pathophysiology ,and more.However,there is still no clear and con-sistent conclusion .Here we reviewed the research progress of HFpEF in terms of the clinical feature ,pathophysiology ,diagnosis ,and treatment in recent years ,which will be beneficial to the clinical diagnosis and treatment of HFpEF for the clinician .
