Abstract
Heart failure with preserved ejection fraction (HFpEF) has progressively emerged as the predominant form of heart failure. Thus, studies on the underlying mechanisms of HFpEF have shifted from pathophysiological to molecular factors. Meanwhile, previous studies have primarily focused on inflammation, oxidative stress, metabolic dysregulation, and impaired cardiac compliance (manifesting as ventricular hypertrophy and interstitial fibrosis). In addition to conventional guideline-directed medical therapies, novel therapeutic strategies targeting these aforementioned pathogenic pathways have been investigated. This review aimed to summarize recent progress in HFpEF pathogenesis and emerging treatment approaches, offering insights for developing novel diagnostic and management strategies.
