RESUMO
BACKGROUND: The use of myocardial reperfusion-mainly via angioplasty-has increased in our region to over 95%. We wondered whether old and very old patients have benefited from this development. METHODS: Setting: Greater Paris Area (Ile-de-France). DATA: Regional registry, prospective, including since 2003, data from 39 mobile intensive care units performing prehospital treatment of patients with ST segment elevation myocardial infarction (STEMI) (<24 h). PARAMETERS: Demographic, decision to perform reperfusion and outcome (in-hospital mortality). PRIMARY ENDPOINT: Reperfusion decision rate by decade over age 70. SECONDARY ENDPOINT: Outcome. RESULTS: We analysed the prehospital management of 27,294 patients. There were 21,311 (78%) men and 5,919 (22%) women with a median age of 61 (52-73 years). Among these patients, 8,138 (30%) were > 70 years, 3,784 (14%) > 80 years and 672 (2%) > 90 years.The reperfusion decision rate was 94%. It decreased significantly with age: 93, 90 and 76% in patients in their seventh, eighth and ninth decade, respectively. The reperfusion decision rate increased significantly over time. It increased in all age groups, especially the higher ones. Mortality was 6%. It increased significantly with age: 8, 16 and 25% in patients in their seventh, eighth and ninth decade, respectively. It significantly decreased over time in all age groups. The odds ratio of the impact of reperfusion decision on mortality reached 0.42 (0.26-0.68) in patients over 90 years. CONCLUSION: the increase in the reperfusion decision rate was the greatest in the oldest patients. It reduced mortality even in patients over 90 years of age.

BACKGROUND: In-hospital mortality of ST-segment-elevation myocardial infarction (STEMI) has decreased drastically. In contrast, prehospital mortality from sudden cardiac arrest (SCA) remains high and difficult to reduce. Identification of the patients with STEMI at higher risk for prehospital SCA could facilitate rapid triage and intervention in the field. METHODS: Using a prospective, population-based study evaluating all patients with STEMI managed by emergency medical services in the greater Paris area (11.7 million inhabitants) between 2006 and 2010, we identified characteristics associated with an increased risk of prehospital SCA and used these variables to build an SCA prediction score, which we validated internally and externally. RESULTS: In the overall STEMI population (n=8112; median age, 60 years; 78% male), SCA occurred in 452 patients (5.6%). In multivariate analysis, younger age, absence of obesity, absence of diabetes mellitus, shortness of breath, and a short delay between pain onset and call to emergency medical services were the main predictors of SCA. A score built from these variables predicted SCA, with the risk increasing 2-fold in patients with a score between 10 and 19, 4-fold in those with a score between 20 and 29, and >18-fold in patients with a score ≥30 compared with those with scores <10. The SCA rate was 28.9% in patients with a score ≥30 compared with 1.6% in patients with a score ≤9 (P for trend <0.001). The area under the curve values were 0.7033 in the internal validation sample and 0.6031 in the external validation sample. Sensitivity and specificity varied between 96.9% and 10.5% for scores ≥10 and between 18.0% and 97.6% for scores ≥30, with scores between 20 and 29 achieving the best sensitivity and specificity (65.4% and 62.6%, respectively). CONCLUSIONS: At the early phase of STEMI, the risk of prehospital SCA can be determined through a simple score of 5 routinely assessed predictors. This score might help optimize the dispatching and management of patients with STEMI by emergency medical services.

BACKGROUND: Heart failure is associated with reduced quality of life, hospitalizations, death and high healthcare costs. Despite care improvements, the rehospitalization rate after an acute heart failure episode, especially for acute heart failure, remains high. METHODS: The Education Strategy for patients with acute Heart Failure (EduStra-HF; ClinicalTrials.gov Identifier NCT03035123) study will randomize patients admitted for acute heart failure in six French hospitals to usual care (control) or therapeutic education (intervention). All patients will be evaluated at baseline and will meet with a therapeutic education nurse before discharge. Those in the usual care arm will have standard appointments with their cardiologist and general practitioner. Those in the intervention arm will have an intensive follow-up schedule of phone calls, home visits and text messages from the therapeutic education nurses, plus cardiologist visits. Patients will be stratified by discharge location (home or cardiac rehabilitation centre) before randomization, and will be followed up for 1 year. The primary outcome will be the readmission rates for acute heart failure during 1 year in the two groups. Secondary outcomes will include: quality of life; time from inclusion to first readmission for acute heart failure; non-heart failure cardiovascular rehospitalization rates; length of stay for heart failure; cardiovascular and all-cause death; rates of patients receiving optimal medical therapies; evolution of knowledge about heart failure; and cost-effectiveness. CONCLUSIONS: This study will assess the efficacy and feasibility of a standardized management strategy for the care and follow-up of patients discharged after hospitalization for acute heart failure. The EduStra-HF strategy will combine various nurse care methods to help prevent rehospitalization.
RESUMO
The e-MUST registry has continuously and comprehensively documented ST-segment elevation myocardial infarctions (STEMIs) managed in the prehospital setting by the 39 Mobile Emergency and Resuscitation Services (SMUR) of the 8 Emergency Medical Assistance System (SAMU) and subsequently managed in the 36 interventional cardiology services in Île-de-France since 2000. This encompasses a population of over 12 million residents. To date, nearly 44,000 patients have been enrolled. The analysis of these findings reflects the real-world management of these patients and the evolution of their care. The results are shared annually with the investigators' teams and have led to around twenty publications. The latest acquired results have demonstrated, in a series of over 630 patients aged over 90, that nonagenarians particularly benefit from prehospital coronary reperfusion decisions, resulting in a nearly 60% reduction in mortality.

The CARDIO-ARSIF registry has been continuously collecting comprehensive data on coronary angiography and percutaneous coronary interventions (PCI) performed in the 36 catheterization laboratories across the Île-de-France region since 2000. Over the period from 2003 to 2022, this registry has recorded information from more than 330,000 patients, encompassing more than one million procedures. Among these procedures, 58% consisted of coronary angiography, 13% were percutaneous coronary interventions (PCI), and the remaining 28% were PCI performed on an ad-hoc basis. This extensive dataset serves as a valuable resource for both qualitative and quantitative assessments of practices and the relevance of procedures in the field of coronary invasive cardiology. The results of these analyses undergo annual validation by a dedicated scientific committee and are shared with the teams of investigators. The exploitation of this data has led to scientific publications, with one notable finding being a consistent reduction in the radiation doses received by patients, regardless of the type of procedure.

Background: While much progress has been accomplished in the understanding of radiation-induced immune effects in tumors, little is known regarding the mechanisms involved at the tumor draining lymph node (TDLN) level. The objective of this retrospective study was to assess the immune and biological changes arising in non-involved TDLNs upon node sparing concurrent chemoradiotherapy (CRT) of non-small cell lung cancer (NSCLC) tumors. Methods: Patients with proven localized (cN0M0) NSCLC, treated by radical surgery plus lymph node dissection with (CRT+) or without (CRT-) neoadjuvant chemoradiotherapy, whereby radiotherapy was targeted on the primary tumor with no significant incidental irradiation of the non-involved TDLN station (stations XI), were identified. Bulk RNA sequencing of TDLNs was performed and data were analyzed based on differential gene expression (DGE) and gene sets enrichment. Results: Sixteen patients were included and 25 TDLNs were analyzed: 6 patients in the CRT+ group (12 samples) and 10 patients in the CRT- group (13 samples). Overall, 1001 genes were differentially expressed between the two groups (CRT+ and CRT-). Analysis with g-profiler revealed that gene sets associated with antitumor immune response, inflammatory response, hypoxia, angiogenesis, epithelial mesenchymal transition and extra-cellular matrix remodeling were enriched in the CRT+ group, whereas only gene sets associated with B cells and B-cell receptor signaling were enriched in the CRT- group. Unsupervised dimensionality reduction identified two clusters of TDLNs from CRT+ patients, of which one cluster (cluster 1) exhibited higher expression of pathways identified as enriched in the overall CRT+ group in comparison to the CRT- group. In CRT+ cluster 1, 3 out of 3 patients had pathological complete response (pCR) or major pathological response (MPR) to neoadjuvant CRT, whereas only 1 out of 3 patients in the other CRT+ cluster (cluster 2) experienced MPR and none exhibited pCR. Conclusion: Neoadjuvant node sparing concurrent CRT of NSCLC patients is associated with distinct microenvironment and immunological patterns in non-involved TDLNs as compared to non-involved TDLNs from patients with non-irradiated tumors. Our data are in line with studies showing superiority of lymph node sparing irradiation of the primary tumor in the induction of antitumor immunity.
RESUMO
BACKGROUND: The time lapse between onset of symptoms and a call to an emergency dispatch center (pain-to-call time) is a critical prognostic factor in patients with chest pain. It is therefore important to identify factors related to delays in calling for help. OBJECTIVES: To analyze whether age, gender, or time of day influence the pain-to-call delay in patients with acute STsegment elevation myocardial infarction (STEMI). MATERIAL AND METHODS: Data were extracted from a prospective registry of STEMI cases managed by 39 mobile intensive care ambulance teams before hospital arrival within 24 hours of onset in our region, the greater metropolitan area of Paris, France. We analyzed the relation between pain-to-call time and the following factors: age, gender, and the time of day when symptoms appeared. We also assessed the influence of pain-to-call time on the rate of prehospital decisions to implement reperfusion therapy. RESULTS: A total of 24 662 consecutive patients were included; 19 291 (78%) were men and 4371 (22%) were women. The median age was 61 (interquartile range, 52-73) years (men, 59 [51-69] years; women, 73 [59-83] years; P .0001). The median pain-to-call time was 60 (24-164) minutes (men, 55 [23-150] minutes; women, 79 [31-220] minutes; P .0001). The delay varied by time of day from a median of 40 (17-101) minutes in men between 5 pm and 6 pm to 149 (43-377) minutes in women between 2 am and 3 am. The delay was longer in women regardless of time of day and increased significantly with age in both men and women (P .001). A longer pain-to-call time was significantly associated with a lower rate of implementation of myocardial reperfusion (P .001). CONCLUSION: Pain-to-call delays were longer in women and older patients, especially at night. These age and gender differences identify groups that would benefit most from health education interventions.
INTRODUCCION: En el dolor torácico, el tiempo desde el inicio de los síntomas hasta el aviso al sistema de emergencias (TAE) es un factor pronóstico decisivo. Es necesario conocer los factores que pueden influir en su duración. OBJETIVO: Analizar el efecto de la edad, el sexo y el momento del día en el TAE en pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMEST). METODO: Se analizaron los datos de un registro regional prospectivo que incluye a todos los pacientes con IAMEST y 24 horas de evolución atendidos por 39 equipos de ambulancias de soporte vital avanzado en un entorno prehospitalario en el área metropolitana de París, Francia. Se analizó el TAE en relación con la edad, el sexo y el momento de aparición de los síntomas. Se valoró la influencia del TAE en la decisión prehospitalaria de tratamiento de reperfusión. RESULTADOS: Se incluyeron 24.662 pacientes consecutivos, de los cuales 19.291 (78%) eran hombres; la edad mediana fue de 61 años (RIC 52-73); 59 (51-69) en hombres y 73 (59-83) en mujeres (p 0,0001). El TAE fue de 60 minutos (24-164); 55 (23-150) minutos en hombres y 79 (31-220) minutos en mujeres (p 0,0001), y oscilaba entre 40 (17-101) minutos en hombres entre las 17:00 y las 18:00 y 149 (43-377) en mujeres entre las 02:00 y las 03:00. Independientemente de la hora de aparición del dolor, el TAE fue mayor en mujeres, y aumentó con la edad, tanto en hombres como en mujeres (p 0,001). El TAE prolongado se asoció con un descenso significativo en la decisión prehospitalaria de tratamiento de reperfusión (p 0,001). CONCLUSIONES: El intervalo de TAE fue más largo en mujeres y pacientes mayores, especialmente por la noche. Estos resultados permiten identificar los grupos de pacientes que más se beneficiarían de medidas de educación sanitaria.

The aim of this study was to provide contemporary data on chronic total occlusion (CTO) prevalence and management in a large unselected population representing the daily activity of cathlabs, in the greater Paris area, and to compare percutaneous coronary intervention (PCI) features in patients with and without CTO. Procedures were collected from the CARDIO-ARSIF (Agence Régionale de Santé Ile de France) registry from 2012 to 2015. Patients with acute coronary syndrome or previous coronary artery bypass grafting were excluded. CTO features were assessed and PCIs with and without CTO were compared. Among 128,739 included patients, 10,468 (8.1%) had at least 1 CTO. Cardiovascular risk-factor burden was higher in the CTO group, which had more patients with multivessel disease (74% vs 24%) and with referral for interventional management (59% vs 33%). Of all PCIs during the study period, 5.7% involved a CTO; this proportion increased significantly over the study period. PCI success rate was 75.9% in the CTO group. CTO-PCI volume per center did not correlate with CTO-PCI success rate. In conclusion, CTO is common in patients who underwent scheduled coronary angiography. Invasive management is done more often in patients with than without CTO. The success rate of PCI in CTO is not associated with case volume per center.

OBJECTIVE: Mortality in patients with ST-segment elevation myocardial infarction (STEMI) has been associated with the volume of activity of percutaneous coronary intervention (PCI) facilities. This observational study investigated whether the coronary reperfusion-decision rate is associated with the volume of activity in a prehospital emergency setting. METHODS: Prospectively collected data for the period 2003-2013 were extracted from a regional registry of all STEMI patients handled by eight dispatch centers (SAMUs) in and around Paris [41 mobile ICU (MICUs)]. A possible association between volume of activity (number of STEMIs) and coronary reperfusion-decision rate, and subsidiarily between volume of activity and choice of technique (fibrinolysis vs. primary PCI), were investigated. Explanatory factors (patient age, sex, delay between pain onset and first medical contact, and access to a PCI facility) were analyzed in a multivariate analysis. RESULTS: Overall, 18 162 patients; male/female 3.5/1; median age 62 (52-72) years were included in the analysis. The median number of STEMIs per MICU was 339 (IQ 220-508) and that of reperfusion-decisions was 94% (91-95). There was no association between the decision rate and the number of STEMIs (P = 0.1). However, the decision rate was associated with age, sex, delay, and access to a PCI facility (P < 0.0001) in a highly significant way. Fibrinolysis was a more frequent option for low-volume (remoter PCI facilities) than high-volume MICUs (30 vs. 16%). CONCLUSION: The decision of coronary reperfusion in a prehospital emergency setting depended on patient characteristics, delay between pain onset and first medical contact, and access to a PCI facility, but not on volume of activity. Promoting fibrinolysis use in underserved areas might help increase the reperfusion-decision rate.

BACKGROUND: Mortality of ST-segment-elevation myocardial infarction (STEMI) decreased drastically, mainly through reduction in inhospital mortality. Prehospital sudden cardiac arrest (SCA) became one of the most feared complications. We assessed the incidence, outcome, and prognosis' predictors of prehospital SCA occurring after emergency medical services (EMS) arrival. METHODS AND RESULTS: Data were taken between 2006 and 2014 from the e-MUST study (Evaluation en Médecine d'Urgence des Strategies Thérapeutiques des infarctus du myocarde) that enrolls all STEMI managed by EMS in the Greater Paris Area, including those dead before hospital admission. Among 13 253 STEMI patients analyzed, 749 (5.6%) presented EMS-witnessed prehospital SCA. Younger age, absence of cardiovascular risk factors, symptoms of heart failure, extensive STEMI, and short pain onset-to-call and call-to-EMS arrival delays were independently associated with increased SCA risk. Mortality rate at hospital discharge was 4.0% in the nonSCA group versus 37.7% in the SCA group ( P<0.001); 26.8% of deaths occurred before hospital admission. Factors associated with increased mortality after SCA were age, heart failure, and extensive STEMI, while male sex and cardiovascular risk factors were associated with decreased mortality. Among patients admitted alive, PCI was the most important mortality-reduction predictor (odds ratio, 0.40; 95% CI, 0.25-0.63; P<0.0001). CONCLUSIONS: More than 1 of 20 STEMI presents prehospital SCA after EMS arrival. SCA occurrence is associated with a 10-fold higher mortality at hospital discharge compared with STEMI without SCA. PCI is the strongest survival predictor, leading to a twice-lower mortality. This highlights the persistently dramatic impact of SCA on STEMI and the major importance of PCI in this setting.

INTRODUCTION: Recent studies reported a decrease in the incidence of acute myocardial infarction. This favorable evolution does not extend to young women. The interaction between gender, risk factors and myocardial infarction incidence remains controversial. OBJECTIVE: To compare the evolution of the age pyramid of patients with ST-elevation myocardial infarction (STEMI) according to gender. METHODS: Data from patients with STEMI managed in pre-hospital settings prospectively collected in the greater Paris area. Evolution of patient demographics and risk factors was investigated. RESULTS: 28,249 patients with STEMI were included in the registry between 2002 and 2014, 21,883 (77%) males and 6,366 (23%) females. The sex ratio did not significantly vary over the study period (p = 0.4). Median patient age was 60.1 years (51.1â»73.0) and was significantly different between males and females, respectively 57.9 (50.0â»68.3) vs. 72.9 years (58.3â»82.2) (p = 0.0004). The median age of males significantly (p = 0.0044) increased from 57.6 (50.1â»70.0) in 2002 to 58.1 years (50.5â»67.8) in 2014. The median age of females significantly (p = 0.0006) decreased from 73.7 (57.9â»81.8) to 69.6 years (57.0â»82.4). The median gap between the age of men and women significantly (p = 0.0002) decreased, from 16.1 to 11.5 years. Prevalence of risk factors was unchanged or decreased except for hypertension which significantly increased in males. The rate of STEMI without reported risk factors increased in both males and females. CONCLUSION: The age of STEMI onset significantly decreased in females, whereas it significantly increased in males. The prevalence of risk factors decreased in males, whereas no significant variation was found in females.
RESUMO
BACKGROUND: The frequency of complex percutaneous coronary interventions (PCIs) has increased in the last few years, with a growing concern on the radiation dose received by the patients. Multicenter data from large unselected populations on patients' radiation doses during coronary angiography (CA) and PCI and temporal trends are lacking. This study sought to evaluate the temporal trends in patients' exposure to radiation from CA and PCI. METHODS AND RESULTS: Data were taken from the CARDIO-ARSIF registry that prospectively collects data on all CAs and PCIs performed in the 36 catheterization laboratories in the Greater Paris Area, the most populated regions in France with about 12 million inhabitants. Kerma area product and Fluoroscopy time from 152 684 consecutive CAs and 103 177 PCIs performed between 2009 and 2013 were analyzed. A continuous trend for a decrease in median [interquartile range] Kerma area product was observed, from 33 [19-55] Gy cm2 in 2009 to 27 [16-44] Gy cm2 in 2013 for CA (P<0.0001), and from 73 [41-125] to 55 [31-91] Gy cm2 for PCI (P<0.0001). Time-course differences in Kerma area product remained highly significant after adjustment on Fluoroscopy time, PCI procedure complexity, change of x-ray equipment, and other patient- and procedure-related covariates. CONCLUSIONS: In a large patient population, a steady temporal decrease in patient radiation exposure during CA and PCI was noted between 2009 and 2013. Kerma area product reduction was consistent in all types of procedure and was independent of patient-related factors and PCI procedure complexity.

AIMS: The mortality rate in patients with STEMI is higher in women than in men. This higher mortality rate is partly accounted for by certain known characteristics inherent in the female population (age, diabetes). Using data from the e-MUST registry on STEMI patients in the Greater Paris area, we assessed the differences between men and women treated with reperfusion strategies. METHODS AND RESULTS: Patients presenting within 24 hours of pain onset between 2006 and 2010 were included in the study. The male and female subpopulations were compared according to their baseline characteristics, their management delays and their early outcomes. Five thousand eight hundred and forty males (78.9%) and 1,557 females (21.1%) were included in the study. In-hospital mortality was significantly higher in women than in men, 143 (9.4%) vs. 254 (4.4%), p<0.0001, with a longer time to treatment initiation, symptoms to call (2.7±3.6 vs. 2.2±3.4 hours, p<0.0001), symptoms to first medical contact (FMC) (3.1±3.7 vs. 2.6±3.4 hours, p<0.0001), and call to FMC (25.6±23.5 vs. 23.6±18.3 min, p=0.02). After adjustment for clinical factors, severity criteria, myocardial infarction (MI) location and delays, mortality remained higher in women than in men with an odds ratio of 1.40 [1.06-1.84], p=0.017. CONCLUSIONS: We demonstrated longer pre-hospital delays and higher in-hospital mortality in women. The increase in the time to treatment alone does not completely explain the persistent increase in mortality. Further studies, public awareness programmes and physician education are necessary to reduce delays and improve the prognosis of STEMI in women.

BACKGROUND: Environmental parameters have been reported to be triggers of acute myocardial infarction (MI). However, the individual role of each parameter is unknown. We quantified the respective association of climate parameters, influenza epidemics and air pollutants with the onset of ST elevation MI (STEMI) in Paris and the surrounding small ring. METHODS: Data from the CARDIO-ARSIF registry (Paris and small ring STEMI population), Météo France (Climate), GROG (Influenza epidemic) and AIRPARIF (Air Pollution) were analyzed. The association between short-term exposure (1 day lag time) to environmental parameters and STEMI occurrence was quantified by time series modeling of daily STEMI count data, using Poisson regression with generalized additive models. RESULTS: Between 2003 and 2008, 11,987 <24H STEMI confirmed by angiography were adjudicated. There was a 5.0% excess relative risk (ERR) of STEMI per 10°C decrease in maximal temperature (95% CI 2.1% to 7.8%: p=0.001) and an 8.9% ERR (95% CI 3.2% to 14.9%: p=0.002) during an influenza epidemic after adjustment on week-days and holidays. Associations were consistent when short-term exposure varied from 2 to 7 days. Associations between lower temperatures and STEMI were stronger in magnitude when influenza epidemic was present. Short-term exposure to climatic parameters or pollutants was not associated with STEMI. CONCLUSIONS: The present population based registry of STEMI suggests that short-term exposure to lower temperature and influenza epidemic is associated with a significant excess relative risk of STEMI. Subjects at risk for MI may benefit from specific protections against cold temperature and influenza infection.

INTRODUCTION: ST-segment-elevation acute myocardial infarction (STEMI) is a therapeutic emergency. Early reperfusion is the key to successful reperfusion. Guidelines recommend organizing regional networks. In France, this starts with a call to a medical dispatch center, the SAMU-centre 15. The aim of this study was to evaluate regional STEMI management using data collected from 2002 to 2010. METHODS: Observational, prospective, multicenter survey. STEMI patient with chest pain lasting for less than 24hours managed by 40 mobile emergency and resuscitation service (SMUR) and 8 emergency medical system (SAMU) from the Greater Paris Area (Île-de-France) were analyzed. Demographic data, cardiovascular risk factors, infarction location, decision of reperfusion and delays were collected. The rate of coronary reperfusion was chosen as the primary endpoint. RESULTS: Eleven thousand five hundred and eighty-eight patients enrolled from 2002 to 2010 were analyzed. Median age was 59.9 (51.0 to 72.9) years; 9080 (78.5%) were men. The number of patients included decreased from 1376 in 2002 to 1119 in 2010. Reperfusion was achieved by fibrinolysis in 2644 (23%) cases and primary angioplasty in 7999 (69%) cases. The rate of decision of coronary reperfusion significantly increased from 86.7% in 2002 to 94.8% in 2010 (P<0.0001). Interaction between the increasing decision of reperfusion and all factors studied (demographics, cardiovascular risk factors, infarct location and delays) was significant only for family history of coronary artery disease (P=0.03). In-hospital mortality was 2.8% (321 cases). CONCLUSION: The number of patients with STEMI managed by the SAMU declined slightly over the past decade. The rate of decision of reperfusion progressively increased up to 95%. Entrance into the network by the SAMU-centre 15 is a guarantee of a wide and early access to the coronary reperfusion.

BACKGROUND: Few data are available on primary percutaneous coronary intervention (pPCI) in nonagenarians. In a large prospective registry on pPCI for STEMI we compared the demographics, procedural and in-hospital outcomes between nonagenarians (age ≥ 90 years) and patients aged < 90 years. METHODS AND RESULTS: We included 26,157 consecutive patients with pPCI in the Greater Paris Area region between 2003 and 2011. Of these, 418 (1.6%) were ≥ 90 years old. Nonagenarians (versus patients < 90 years) were more likely to be female (62.3% versus 22.5%, p < 0.0001), nonsmokers (81.6% versus 36.7%, p < 0.0001), in cardiogenic shock (Killip IV) upon admission (10.5% versus 4.8%, p < 0.001), and had significant co-morbidities. Over two-thirds of patients underwent procedures via the radial artery (61% versus 72.1%, p = 0.007). Both groups had high and similar angiographic success rates (98.1% versus 98.7%, p = 0.33). Drug-eluting stents were used less often in nonagenarians (4.4% versus 16.7%, p < 0.0001). Hospital mortality was significantly much higher in patients over 90 years old (24.9% versus 5.1%, p < 0.001) in univariate analysis. After adjustment for sex, cardiogenic shock, diabetes, triple vessel disease, drug-eluting stent use and glycoprotein IIb/IIIa inhibitors use, mortality remains higher in nonagenarian patients (OR: 4.31; 95% CI: 3.26-5.71, p < 0.0001). CONCLUSIONS: In a real-world setting, we found important demographic differences in nonagenarian compared to younger patients. Despite achieving a high rate of reperfusion with pPCI using mainly radial access, similar to that achieved in younger patients, hospital mortality was higher in nonagenarians.

BACKGROUND: Tako-Tsubo cardiomyopathy (TTC) is a recently described medical entity and the incidence of TTC in a global population is still uncertain. We sought to prospectively assess the incidence of TTC in a large urban area. METHODS AND RESULTS: We included all consecutive patients referred for coronary angiography in three hospitals located in Paris and its suburbs. We prospectively estimated the percentage of TTC among patients referred for coronary angiography and extrapolated the number of cases of TTC in the greater Paris area (11,598,866 inhabitants) according to the CARDIO-ARHIF registry (government agency). Among 2547 patients (2972 coronary angiographies) including 815 acute coronary syndromes, 20 patients presented with TTC (19 women, mean age 66 ± 13 years). The percentage of TTC among suspected acute coronary syndromes was 2.5% (8.2% in women versus 0.2% in men, p<0.001). In the CARDIO-ARHIF registry, we individualized 51,403 coronary angiographies performed in all catheterization laboratories in one year (13,820 women and 10,246 women ≥ 60 years). In this region, the yearly number of TTC cases is estimated to be 346 (95% CI: 216-520). The annual incidence of TTC is estimated to be 29.8 per 1,000,000 inhabitants (95% CI: 18.6-44.9), 48.2 per 1,000,000 inhabitants (95% CI: 29.7-73.0) among women and 187.4 per 1,000,000 inhabitants (95% CI: 103.3-307.2) among women ≥ 60 years. CONCLUSIONS: Within a large urban agglomeration, the incidence of TTC is high in women ≥ 60 years. The current rate of this recently described cardiomyopathy has been underestimated in previous retrospective studies and will probably rise with the increase of life expectancy.

BACKGROUND: ESC guidelines recommend a shorter (90 min) delay for the use of primary percutaneous intervention (pPCI) in patients presenting within the first 2h of pain onset. Using registry data on STEMI patients in the Greater Paris Area, we assessed changes between 2003 and 2008 in the rates of pPCI, pre-hospital fibrinolytic therapy (PHF) and time delays in patients presenting within 2h of STEMI pain onset. METHODS: The Greater Paris Area was divided in 3 regions: Paris, the small and large rings. Patients were divided in three groups according to their reperfusion strategy: a) PHF, b) timely pPCI (FMC to balloon inflation time < 90 min), and c) late pPCI (FMC to balloon inflation time > 90 min). RESULTS: Among the 5592 patients included, 1695 (39%) had PHF, 1266 (29%) had timely pPCI, and 1415 (32%) had late pPCI. Over the 6 years, there was a sharp increase in timely pPCI in all regions, balanced by a decrease in PHF. The rate of late pPCI remained globally stable, with a decrease in Paris, stabilization in the small ring, and an increase in the large ring, where the density of catheterization laboratories was the lowest. By multivariate analysis, using on-time pPCI as a reference group, mortality was higher in the PHF and late pPCI groups. CONCLUSIONS: In areas with a low density of pPCI centers, efforts should be made to improve the timeliness of pPCI. Otherwise, PHF followed by an immediate transfer to a pPCI capable hospital may be considered.
