Gaps in Guideline-Directed Medical Therapy for Heart Failure: A Cross-Sectional Study in an Underserved Population.
Article in Cureus, 2026. 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
backgroundHeart failure (HF) remains a major clinical and public health challenge. Guideline-directed medical therapy (GDMT) has been shown to improve outcomes in patients with HF; however, gaps in the prescription and implementation of these therapies persist. These treatment gaps may contribute to suboptimal disease management and adverse clinical outcomes, highlighting the need to better understand patterns of GDMT utilization in diverse patient populations. In this study, we assessed and evaluated the prescribing patterns of GDMTs to an underserved population at an urban federally qualified health center (FQHC).
methodsWe conducted a retrospective chart review of patients diagnosed with HF from May 2022 to June 2024 to assess the prescription of GDMT. Patients were classified based on echocardiographic findings as HF with reduced ejection fraction (HFrEF) (< 50%) and HF with preserved ejection fraction (HFpEF) (≥ 50%). Baseline demographics and prescription of GDMTs were compared between the two HF diagnoses.
resultsFifty patients with HF were identified in the study period, including 41 with HFrEF and nine with HFpEF. There was a significant difference in the mean age between patients diagnosed with HFpEF (68 years) as compared to patients with HFrEF (58 years) (p=0.02). Among patients with HFrEF, 93% (n=38) were prescribed beta-blockers (BB), 83% (n=34) were prescribed angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers/angiotensin receptor-neprilysin inhibitors (ACEi/ARB/ARNi), 29% (n=12) were prescribed mineralocorticoid receptor antagonists (MRA), and 34% (n=14) were prescribed sodium-glucose cotransporter-2 inhibitors (SGLT2). Prescriptions for these medical therapies were similar among patients with HFpEF, except that 0% were prescribed an SGLT2 medication (p=0.05 for comparison with patients with HFrEF).
conclusionsGDMT is under-prescribed in underserved populations, underscoring the need for specific interventions to address financial, systemic, and educational barriers. Interventions such as patient education initiatives, financial counseling support, provider training programs, and policy changes to improve medication affordability and access should be prioritized to help close these treatment gaps.
