Abstract：
Heart failure, a growing concern in the United States, significantly impacts both morbidity and mortality. Classified by ejection fraction, heart failure with preserved ejection fraction (HFpEF) now accounts for half of all cases and is steadily rising. Unlike its counterpart, heart failure with reduced ejection fraction (HFrEF), HFpEF lacks clear management guidelines. Recognizing this critical gap, we aim to review existing recommendations and formulate effective management strategies for HFpEF.
摘要：
心力衰竭,在美国日益受到关注，显着影响发病率和死亡率。按射血分数分类，射血分数保留的心力衰竭（HFpEF）现在占所有病例的一半，并且正在稳步上升。与它的对应物不同，射血分数降低的心力衰竭（HFrEF），HFpEF缺乏明确的管理指南。认识到这一关键差距，我们的目标是审查现有的建议，并制定有效的HFpEF管理策略。
