Evaluation of prescribing adherence to guideline-directed medical therapy in patients with chronic heart failure: a retrospective study at the National Heart Centre in Oman.

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
backgroundGuideline-directed medical therapy (GDMT) improves survival and quality of life in patients with heart failure with reduced ejection fraction (HFrEF). However, real-world adherence to these guidelines remains suboptimal. This study aimed to evaluate prescribing adherence to GDMT in HFrEF patients using a global guideline adherence scoring tool.
methodsThis retrospective study included adult patients with HFrEF (left ventricular ejection fraction ≤ 40%) attending the Heart Failure Clinic at the National Heart Centre in Oman between January and June 2022. GDMT adherence was assessed based on 2021 European Society of Cardiology guidelines. Adherence levels were categorized as good (all indicated GDMT at ≥ 50% of target dose), moderate (more than half at ≥ 50%), or poor (less than half or < 50%). Descriptive statistics and chi-square tests were used to identify associations.
resultsOf the 259 patients included (mean age 57 ± 13.6 years, 70% male), 71% had good adherence, 22% moderate, and 7% poor. Target dose attainment varied by drug class: 78% for beta-blockers, 63% for ACEI/ARB/ARNI, 96% for MRAs, and 100% for ivabradine. Suboptimal GDMT (< 50% target dose) was significantly associated with hypertension (P = 0.004), dilated cardiomyopathy (P = 0.015), chronic kidney disease (P = 0.001), and older age (P = 0.004).
conclusionPrescribing adherence to GDMT in Oman is consistent with international data. Suboptimal titration was significantly linked to older age and comorbidities, suggesting that perceived frailty and clinical complexity may influence physician prescribing patterns. Efforts to improve individualized, patient-centered GDMT titration are warranted.
