Nearly half of all patients who have heart failure have preserved ejection fraction (HFpEF). Patients who have HFpEF tend to be older, female, and hypertensive, and characteristically display increased ventricular and arterial stiffening. In this article, we discuss the pathophysiology of abnormal ventriculoarterial stiffening and how it affects ventricular function, cardiovascular hemodynamics, reserve capacity, and symptoms. We conclude by exploring how novel treatment strategies targeting abnormal ventricular-arterial interaction might prove useful in the treatment of patients who have HFpEF.
大约一半的心衰患者射血分数保留(HFpEF)。HFpEF 患者往往年龄较大、女性、高血压,并表现出心室和动脉僵硬度增加。本文讨论了异常室-动脉僵硬度的病理生理学,以及它如何影响心室功能、心血管血流动力学、储备能力和症状。最后,我们探讨了针对异常室-动脉相互作用的新型治疗策略如何在 HFpEF 患者的治疗中证明有用。
