Management of Antithrombotic Therapy in Patients With Coexisting Atrial Fibrillation and Coronary Artery Disease Who Underwent Percutaneous Coronary Intervention Within the Last Year.
Article in Clinical cardiology, 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
backgroundCoronary artery disease (CAD) is a common comorbidity in patients with atrial fibrillation (AF), and optimal antithrombotic medication improves clinical outcomes in this high-risk population. The aim of our study was to describe antithrombotic drug regimens in different patient cohorts.
methodsWe investigated data from the prospective Helios Heart registry (H2) and the Heart Center Leipzig routine clinical database (HZL). We included inpatient cases with AF and CAD (hospitalized from March 2021 to July 2024 [H2] or January 2017 to December 2021 [HZL]), who underwent percutaneous coronary intervention (PCI) within the last 12 months. Information on clinical characteristics, coronary interventions, and medication prescribed was obtained from electronic case report forms and/or administrative data based on ICD-10, OPS, and ATC codes.
resultsWe included 3481 (HZL), and 205 (H2) index cases with comparable baseline characteristics. Overall, 92.5% (HZL) and 87.6% (H2) of patients were on any anticoagulation, and 93.0% (HZL) and 80.2% (H2) were prescribed ≥ 1 antiplatelet agent. There were relevant differences in antithrombotic therapy when stratifying for PCI timing. Factors associated with higher (older age) or lower (comorbidity burden, antiplatelet treatment, prior left atrial appendage occlusion) prescription rates of OAC were identified. OAC therapy without adjunctive antiplatelet therapy was associated with an increased rate of rehospitalization for major adverse cardiovascular events at 12 months (HZL).
conclusionWe presented current data on antithrombotic drug utilization in patients with AF and CAD and found comorbidity burden, concomitant antiplatelet treatment and other factors to be associated with lower anticoagulant prescription rates.
