Impact of multiple stent implantation on periprocedural myocardial infarction in patients undergoing planned pci in a clinically stable setting: insights from a single-centre cohort study.
Article in BMC cardiovascular disorders, 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
introductionAcute coronary syndrome (ACS) is a critical cardiovascular emergency frequently treated with percutaneous coronary intervention (PCI). Despite its benefits, PCI is associated with a substantial risk of periprocedural myocardial infarction (PMI), particularly among patients receiving multiple stents. This study aims to explore the incidence and determinants of PMI in ACS patients undergoing planned PCI in a clinically stable setting.
methodsThis retrospective single-center study enrolled ACS patients undergoing planned PCI in a clinically stable setting between June 2018 and August 2022. Patients were classified into single-stent (SSG) and multi-stent (MSG) groups. PMI was defined by Academic Research Consortium-2 criteria, and multivariable logistic regression was used to identify factors associated with PMI.
resultsA total of 330 patients with ACS were initially screened, and 222 were ultimately included, comprising 126 in the single-stent group (SSG) and 96 in the multi-stent group (MSG). PMI occurred more frequently in the MSG than in the SSG (16.7% vs. 7.9%, p = 0.045). Compared with the SSG, the MSG had fewer single-vessel lesions, more left circumflex artery involvement, and larger stent diameters, indicating greater lesion and procedural complexity. Multivariable logistic regression showed that both AMI (OR = 2.804, 95% CI: 1.122-7.010; p = 0.027) and a higher number of implanted stents (OR = 2.533, 95% CI: 1.012-6.340; p = 0.047) were associated with PMI.
conclusionMultiple stent implantation during planned PCI is associated with a higher risk of PMI. Careful procedural planning may help reduce PMI incidence in patients with complex coronary anatomy.
