Evaluating the Clinical Outcomes of Empagliflozin in Heart Failure Patients With Preserved Ejection Fraction: A Systematic Review.
Review in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Heart failure with preserved ejection fraction (HFpEF) represents a significant clinical challenge due to its complex pathophysiology and limited therapeutic options. This systematic review evaluates the efficacy and safety of empagliflozin, a sodium-glucose co-transporter 2 (SGLT2) inhibitor, in patients with HFpEF. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we analyzed 11 studies, predominantly from the EMPEROR-Preserved trial and its sub-analyses, investigating empagliflozin in HFpEF patients. Our findings consistently demonstrate that empagliflozin significantly reduces heart failure hospitalizations (HR 0.71, 95% CI 0.60-0.83) across diverse patient populations. This benefit was observed regardless of sex, age, diabetes status, blood pressure, and frailty levels, although effects were attenuated in patients with higher ejection fractions and in severely frail individuals. Notably, empagliflozin did not significantly reduce cardiovascular mortality, although a non-significant trend toward benefit was observed in certain subgroups. Additional benefits included slowed decline in renal function and improved quality of life measures. The safety profile was favorable across all studies, with good tolerability even in elderly and frail populations. These findings position empagliflozin as a valuable addition to the limited therapeutic armamentarium for HFpEF, particularly for reducing hospitalizations and improving symptoms, though its impact on mortality appears limited. Future research should focus on identifying specific HFpEF phenotypes that derive maximal benefit from empagliflozin and evaluating its long-term efficacy, optimal combination strategies, and real-world effectiveness across diverse populations.
