Percutaneous coronary intervention, coronary artery bypass grafting and mortality from acute myocardial infarction in EU15+ countries, 2006-2020: a secondary analysis of the OECD database.
Observational study in BMJ open, 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
objectiveCoronary revascularisation practices have evolved over the last three decades. This study sought to examine the variations in percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) rates, alongside mortality from acute myocardial infarction (AMI) across a group of 16 high-income countries between 2006 and 2020.
designRetrospective observational analysis using data from the Organisation for Economic Co-operation and Development (OECD) database between 2006 and 2020. Estimated annual percent change in revascularisation was analysed using Joinpoint regression model, and mortality rates were evaluated using the locally weighted scatterplot smoothing model.
settingPublicly available data on PCI and CABG procedure rates alongside AMI mortality rate from 2006 to 2020.
participants16 countries from the OECD database.
interventionsNot applicable.
main outcome measuresStandardised PCI and CABG procedure rates and AMI age-standardised mortality rate (ASMR) from 2006 to 2020.
resultsOver the 15 year period, 14.0 million PCI and 2.8 million CABG procedures were collectively recorded across 16 countries. PCI rates varied among nations, but from 2006 to 2020 increased in 11 of the 16 nations overall, led by Finland (+36.0%), Ireland (+34.5%) and France (+31.5%). Meanwhile, CABG rates declined in 14 out of the 16 countries, with Luxembourg (-71.3%), the UK (-62.6%) and Finland (-60.6%) experiencing the most substantial decreases. Throughout the study period, the PCI-to-CABG ratio increased, while AMI ASMR decreased consistently across all countries.
conclusionsDespite evidence supporting CABG over PCI in specific scenarios, CABG rates have declined, and PCI rates have increased. Possible factors for this trend may include patient preference and advancement in interventional techniques. The varied use of PCI among these nations, alongside a sustained decline in AMI mortality rates, may be expected given the importance of optimal medical therapy in the management of ischaemic heart disease. The results further suggest the significance of factors beyond revascularisation in driving improved outcomes.
