Article Synopsis
- Despite advancements in stent technology, there's still a notable risk of in-stent restenosis (ISR) after procedures like PCI, and comprehensive data on this issue is limited.
- A study analyzed data from the France-PCI registry between 2014 and 2018, focusing on patients with ISR lesions, finding that 7.3% of the patients treated had ISR PCI, mostly involving older individuals with comorbidities like diabetes.
- The results revealed that those undergoing ISR PCI had higher rates of complications after one year compared to non-ISR patients, indicating a need for further research and improved techniques in managing ISR.
Early mortality post-ST-segment elevation myocardial infarction (STEMI) in France remains high. The multicentre France Percutaneous Coronary Intervention Registry includes every patient undergoing coronary angiography in France. We analyzed the prevalence and impact of unmodifiable and modifiable risk factors on 30-day survival in patients experiencing STEMI.

Background: FFR has become the invasive gold standard to quantify myocardial ischemia generated by a coronary stenosis in patients with chronic coronary syndrome, but in clinical practice it is still underutilised to guide PCI compared to angiography (angio).
Methods: We extracted from the FrancePCI database all chronic coronary syndrome patients treated with PCI for coronary stenosis <90% between 2014 and 2019.
Article Synopsis
- The study examines the relationship between first medical contact-to-balloon time and 1-year mortality in patients with ST-elevation myocardial infarction (STEMI), focusing on the effects of direct vs. indirect transfer to cardiac catheterization laboratories (CCLs).
- Out of 2,206 STEMI patients, those indirectly admitted to CCL had a higher mortality rate (14.6%) compared to direct admissions (7.7%), highlighting that indirect admissions correlate with worse outcomes despite similar FMC-to-balloon times.
- Key factors influencing indirect admission included older age and the type of initial medical contact (like paramedic response), indicating a need for better population education and care coordination, especially for elderly
Growing use of fractional flow reserve (FFR) and intracoronary imaging techniques by optical coherence tomography or intravascular ultrasound has raised concerns about additional exposure during coronary angiography and percutaneous coronary interventions (PCIs). Using data from the prospective CRAC-France PCI Prospective Multicentre registry, we sought to evaluate the effect of these new techniques on the radiation dose to patients undergoing coronary procedures. Data on Kerma Area Product (PKA), total air kerma (KAr) and fluoroscopy time from 42 182 coronary procedures were retrospectively compared, using multivariable linear regression, according to whether they included FFR and intracoronary imaging.
