Complex versus non-complex percutaneous coronary intervention in patients with atrial fibrillation: a real-world study.
Observational study in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundPatients with atrial fibrillation (AF) often underwent percutaneous coronary intervention (PCI), and the complexity of PCI has risen in recent years. However, there is limited data available on clinical outcomes in patients with AF who underwent complex PCI.
methodsThis was a prospective, observational study. Complex PCI was defined as PCI performed to ≥ 3 separate major coronary vessels; ≥3 stents implanted; ≥3 lesions treated; or total stented length > 60 mm. The primary outcome was defined as major adverse cardiovascular event (MACE) including all-cause death, spontaneous myocardial infarction (MI), stroke/ transient ischemic attack (TIA), systemic embolism or ischemia-driven revascularization. The secondary outcome was defined as net adverse clinical events (NACE), which included major adverse cardiovascular events (MACE) and major bleeding.
resultsA total of 1132 patients who underwent PCI with AF were enrolled consecutively. The mean age was 67 ± 9, and 75.1% were male. 320 participants (28.2%) underwent complex PCI. During a median follow-up of 1045 days (interquartile range: 666-1327), the primary outcome occurred in 52 out of 320 patients (16.2%), while the secondary outcome was observed in 55 out of 320 patients (17.2%) in the complex PCI group. MACE showed no differences between groups (hazard ratio [HR], 1.30; 95% confidence interval [CI], 0.93-1.82), nor did NACE (HR:1.34, 95%CI: 0.97-1.85). Patients with complex PCI still had a higher likelihood of experiencing spontaneous MI (HR, 2.17, 95%CI, 1.00-4.70) and ischemic driven revascularization (HR, 1.86, 95%CI, 1.01-3.45) after adjusted for confounders.
conclusionThe complexity of PCI was an independent risk factor for adverse clinical outcomes, particularly for myocardial infarction and revascularization events in patients with atrial fibrillation. However, it was not associated with major bleeding, all-cause mortality, or stroke/TIA. CLINICAL TRIAL NUMBER: Not applicable.
