RESUMEN
BACKGROUND: Despite the evolution of stent technology, there is a non-negligible risk of in-stent restenosis (ISR) after Percutaneous coronary intervention (PCI). Large-scale registry data on the prevalence and clinical management of ISR is lacking. METHODS: The aim was to describe the epidemiology and management of patients with ≥1 ISR lesions treated with PCI (ISR PCI). Data on characteristics, management and clinical outcomes were analyzed for patients undergoing ISR PCI in the France-PCI all-comers registry. RESULTS: Between January 2014 and December 2018, 31,892 lesions were treated in 22,592 patients, 7.3 % of whom underwent ISR PCI. Patients undergoing ISR PCI were older (68.5 vs 67.8; p < 0.001), and more likely to have diabetes (32.7 % vs 25.4 %, p < 0.001), chronic coronary syndrome or multivessel disease. ISR PCI concerned drug eluting stents (DES) ISR in 48.8 % of cases. Patients with ISR lesions were more frequently treated with DES than drug eluting balloon or balloon angioplasty (74.2 %, 11.6 % and 12.9 %, respectively). Intravascular imaging was rarely used. At 1 year, patients with ISR had higher target lesion revascularization rates (4.3 % vs. 1.6 %; HR 2.24 [1.64-3.06]; p < 0.001). CONCLUSIONS: In a large all-comers registry, ISR PCI was not infrequent and associated with worse prognosis than non-ISR PCI. Further studies and technical improvements are warranted to improve the outcomes of ISR PCI.

OBJECTIVES: We sought to compare, in a national French registry (FrancePCI), the clinical impact of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared with angio-guided PCI at 1 year. 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. Our composite clinical endpoint was the rate of major adverse clinical events (MACE). RESULTS: Fourteen thousand three hundred eighty-four patients with 1-year clinical follow-up were included. Among them, 13,125 had angio-guided PCI (91%) and 1259 (9%) had FFR-guided PCI. We observed a significantly higher rate of MACE in the angio-guided group versus the FFR-guided group: 1478 (11.3%) versus 100 (7.9%) (p < 0.0001), respectively, with hazard ratio (HR) of 1.440, 95% confidence interval (CI) [1.211-1.713] (p = 0.0004). This result was driven by the higher occurrence of death in the angio-guided group versus the FFR-guided-group: 506 (3.9%) versus 17 (1.4%) (p < 0.0001), respectively, with HR of 2.845, 95% CI [2.099-3.856] (p < 0.0001). After adjustment for potential confounding factors, HRs were 1.287, 95% CI [1.028-1.613] (p = 0.028) for MACE and 2.527, 95% CI [1.452-4.399] (p = 0.001) for death. No significant differences between angio-guided PCI and FFR-guided PCI were observed for other clinical endpoints. CONCLUSIONS: FFR-guided PCI improves outcome at 1 year compared to angio-guided PCI with a reduction of 64% of death.

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. In coronary angiography, FFR was associated with longer fluoroscopy time and higher PKA (21.0 vs. 18.9 Gy.cm2) and KAr (372 vs. 299 mGy) (all p < 0.001). Intracoronary imaging was associated with longer fluoroscopy time, higher contrast volume (both p < 0.001), lower PKA (18.3 vs. 19.0 Gy.cm2, p = 0.02) and similar KAr. In PCI, FFR was associated with a moderate increase in KAr (682 vs. 626 mGy, p < 0.01) but not PKA (35.9 vs. 33.7 Gy.cm2, p = 0.34). For intracoronary imaging, there were no differences between groups, except for contrast volume. Increased patient exposure associated with FFR and intracoronary imaging is moderate in diagnostic coronary angiography and minimal or none in PCI, provided optimization techniques are used. It should not be a limitation on the use of these techniques given the important additional information they provide.

BACKGROUND: ST-elevation myocardial infarction (STEMI) patients with multivessel disease (MVD) are associated with a worse prognosis. However, few comparisons are available according to coronary status in the era of modern reperfusion and optimized secondary prevention. HYPOTHESIS: We hypothesized that the difference in prognosis according to number of vessel disease in STEMI patients has reduced. METHODS: All consecutive STEMI patients undergoing primary percutaneous coronary intervention (PCI) within 24 h of symptoms onset between January 1, 2014 and June 30, 2016 enrolled in the CRAC (Club Régional des Angioplasticiens de la région Centre) France PCI registry were analyzed. Baseline characteristics, management, and outcomes at 1-year were analyzed according to coronary status (one-, two-, and three-VD). RESULTS: A total of 1886 patients (mean age 62.2 ± 14.0 year; 74% of male) were included. Patients with MVD (two or three-VD) represented 53.7%. They were older with higher cardiovascular risk factor profile. At 1 year, the rate of major adverse cardiovascular events (MACE, defined as all-cause death, stroke or re-MI) was 10%, 12%, and 12% in one-, two, and three-VD respectively (p = .28). In multivariable adjusted Cox proportional hazard regression model, two- and three-VD were not associated with higher rate of MACE compared to patients with single VD (HR, 1.09; 95%CI 0.76-1.56 for two-VD; HR, 0.74; 95%CI 0.48-1.14 for three-VD). CONCLUSIONS: MVD still represents an important proportion of STEMI patients but their prognoses were not associated with worse clinical outcomes at 1-year compared with one-VD patients in a modern reperfusion area and secondary medication prevention.

Objectives: The aim of this study was to assess the impact of the coronavirus disease 2019 (COVID-19) outbreak on incidence, delays, and outcomes of ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI) in France. Methods: We analyzed all patients undergoing PPCI <24 hours STEMI included in the prospective France PCI registry. The 2 groups were compared on mean monthly number of patients, delays in the pathway care, and in-hospital major adverse cardiac events (MACE: death, stent thrombosis, myocardial infarction, unplanned coronary revascularization, stroke, and major bleeding). Results: From January 15, 2019 to April 14, 2020, 2064 STEMI patients undergoing PPCI were included: 1942 in the prelockdown group and 122 in the lockdown group. Only 2 cases in the lockdown group were positive for COVID-19. A significant drop (12%) in mean number of STEMI/month was observed in the lockdown group compared with prelockdown (139 vs 122, P < 0.04). A significant increase in "symptom onset to first medical contact" delay was found for patients who presented directly to the emergency department (ED) (238 minutes vs 450 minutes; P = 0.04). There were higher rates of in-hospital MACE (7.7% vs 12.3%; P = 0.06) and mortality (4.9% vs 8.2%; P = 0.11) in the lockdown group but the differences were not significant. Conclusion: According to the multicenter France PCI registry, the COVID-19 outbreak in France was associated with a significant decline in STEMI undergoing PPCI and longer transfer time for patients who presented directly to the ED. Mortality rates doubled, but the difference was not statistically significant.
