Transplantation of kidneys from uncontrolled donation after circulatory determination of death: comparison with brain death donors with or without extended criteria and impact of normothermic regional perfusion.

The aim of this study was to compare the outcomes of kidney transplants from uncontrolled DCD (uDCD) with kidney transplants from extended (ECD) and standard criteria donors (SCD). In this multicenter study, we included recipients from uDCD (n = 50), and from ECD (n = 57) and SCD (n = 102) who could be eligible for a uDCD program. We compared patient and graft survival, and kidney function between groups. To address the impact of preservation procedures in uDCD, we compared in situ cold perfusion (ICP) with normothermic regional perfusion (NRP). Patient and graft survival rates were similar between the uDCD and ECD groups, but were lower than the SCD group (P < 0.01). Although delayed graft function (DGF) was more frequent in the uDCD group (66%) than in the ECD (40%) and SCD (27%) groups (P = 0.08 and P < 0.001), graft function was comparable between the uDCD and ECD groups at 3 months onwards post-transplantation. The use of NRP in the uDCD group (n = 19) was associated with a lower risk of DGF, and with a better graft function at 2 years post-transplantation, compared to ICP-uDCD (n = 31) and ECD. In conclusion, the use of uDCD kidneys was associated with post-transplantation results comparable to those of ECD kidneys. NRP preservation may improve the results of uDCD transplantation.

Overcrowding in the Dispatching Centre During the COVID-19 Crisis: Are Medical Students a Resource?

INTRODUCTION: In February, the emergence of COronaVIrus Disease 2019 (COVID - 19) in France made it necessary to rapidly adapt emergency and SAMU services in order to take care of many infected patients. To respond to the increase in the number of calls in the dispatch centers, reinforcements were necessary on the fronts of the Medical Regulation Assistants (ARM). The aim of this study was to assess the relevance of medical students' responses to first calls exclusively concerning COVID-19. METHODS: This prospective, observational cohort study was carried out at the University Hospital Centre (CHU) in Angers. Twenty medical students mostly in the 5th year were voluntarily enrolled in the first line COVID-19 call taker team. Calls on the 1st, 3rd, and 5th starting day for each medical student, and randomly selected calls from the experienced first-line call taker were listened to by a medical expert to assess the adequate level of prioritization and orientation (emergency physician or general practitioner). The percentage of agreement between the expert, students, and experienced first-line call handlers were assessed. All participants gave their free consent to participate. The study was approved by the Ethics Committee of Angers (N° 2020-48). RESULTS: From March 18 to April 23, 2020, 302 calls from medical students (n = 20 students) and 40 calls from experienced first-line call handlers were analyzed. The average prioritization agreement rate between the expert and students was 76.16% (95% Confidence Interval: 71.04 to 80.62%) (n = 230/302) compared to 87.50% (95% CI: 73.9 to 94.5%) (n = 45/50) for the experienced first-line call handlers (P = 0.15). Medical students took more time per call with an absolute difference of 2 minutes 16 seconds (P < 0.001). CONCLUSION: The lessons to be observed from this COVID-19 crisis are that in the early days of increasing calls heralding a strain on the healthcare system, support by medical students must be considered.

Noninvasive ventilation use in French out-of-hospital settings: a preliminary national survey.

OBJECTIVE: The objective of our study was to describe noninvasive ventilation (NIV) practices (pressure support ventilation and continuous positive airway pressure) in French out-of-hospital mobile intensive care units (SMUR) and their compliance with national consensus guidelines. METHOD: Online inquiry into practices of NIV among managers of French SMUR. Analyzed data include types of NIV devices and use of NIV. RESULTS: Upon 218 SMUR referenced within the SAMU de France database, 118 questionnaires (54%) were processed. Noninvasive ventilation equipment: 91% of the SMUR with at least one type of NIV device (continuous positive airway pressure only=82%; pressure support ventilation only=59%; both=50%) but frequently not with recommended devices. Use of NIV: for acute cardiogenic pulmonary edema, practices were compliant with recommendations in 80% of cases, although there was still room for improvement. For other pathologies, practices were very heterogeneous, not always properly assessed, and frequently not compliant with recommendations. CONCLUSION: To conclude, NIV use in the out-of-hospital setting in France seems to meet current recommendations for acute cardiogenic pulmonary edema but not for other pathologies. This could be improved by the use of written procedures, conduction of further studies, and promotion of compliance through education.

Impact of routine percutaneous coronary intervention after out-of-hospital cardiac arrest due to ventricular fibrillation.

INTRODUCTION: Since 2003, we have routinely used percutaneous coronary intervention (PCI) and mild therapeutic hypothermia (MTH) to treat patients < 80 years of age after out-of-hospital cardiac arrest (OHCA) related to ventricular fibrillation. The aim of our study was to evaluate the prognostic impact of routine PCI in association with MTH and the potential influence of age. METHODS: We studied 111 consecutive patients resuscitated successfully following OHCA related to shock-sensitive rhythm. They were divided into five groups according to age: < 45 years (n = 22, group 1), 45 to 54 years (n = 27, group 2), 55 to 64 years (n = 22, group 3), 65 to 74 years (n = 23, group 4) and ≥75 years (n = 17, group 5). Emergency coronary angiography was performed in hemodynamically stable patients < 80 years old, regardless of the electrocardiogram pattern. MTH was targeted to a core temperature of 32°C to 34°C for 24 hours. RESULTS: Most patients (73%) had coronary heart disease, although its incidence in group 1 was lower than in other groups (41% versus 81%; P = 0.01). In group 1, all patients but one underwent coronary angiography, and 33% of them underwent associated PCI. In group 5, only 53% of patients underwent a coronary angiography and 44% underwent PCI. Overall in-hospital survival was 54%, ranging between 52% and 64% in groups 1 to 4 and 24% in group 5. Time from collapse to return of spontaneous circulation was associated with mortality (odds ratio (OR) = 1.05 (25th to 75th percentile range, 1.03 to 1.08); P < 0.001), whereas PCI was associated with survival (OR = 0.30 (25th to 75th percentile range, 0.11 to 0.79); P = 0.01). CONCLUSIONS: We suggest that routine coronary angiography with potentially associated PCI may favorably alter the prognosis of resuscitated patients with stable hemodynamics who are treated with MTH after OHCA related to ventricular fibrillation. Although age was not an independent cause of death, the clinical relevance of this therapeutic strategy remains to be determined in older people.

Continuous positive airway pressure for respiratory support during COVID-19 pandemic: a frugal approach from bench to bedside.

BACKGROUND: We describe a frugal approach (focusing on needs, performance, and costs) to manage a massive influx of COVID-19 patients with acute hypoxemic respiratory failure (AHRF) using the Boussignac valve protected by a filter ("Filter Frugal CPAP", FF-CPAP) in and out the ICU. METHODS: (1) A bench study measured the impact of two filters with different mechanical properties on CPAP performances, and pressures were also measured in patients. (2) Non-ICU healthcare staff working in COVID-19 intermediate care units were trained with a video tutorial posted on a massive open online course. (3) A clinical study assessed the feasibility and safety of using FF-CPAP to maintain oxygenation and manage patients out of the ICU during a massive outbreak. RESULTS: Bench assessments showed that adding a filter did not affect the effective pressure delivered to the patient. The resistive load induced by the filter variably increased the simulated patient's work of breathing (6-34%) needed to sustain the tidal volume, depending on the filter's resistance, respiratory mechanics and basal inspiratory effort. In patients, FF-CPAP achieved pressures similar to those obtained on the bench. The massive training tool provided precious information on the use of Boussignac FF-CPAP on COVID-19 patients. Then 85 COVID-19 patients with ICU admission criteria over a 1-month period were studied upon FF-CPAP initiation for AHRF. FF-CPAP significantly decreased respiratory rate and increased SpO2. Thirty-six (43%) patients presented with respiratory indications for intubation prior to FF-CPAP initiation, and 13 (36%) of them improved without intubation. Overall, 31 patients (36%) improved with FF-CPAP alone and 17 patients (20%) did not require ICU admission. Patients with a respiratory rate > 32 breaths/min upon FF-CPAP initiation had a higher cumulative probability of intubation (p < 0.001 by log-rank test). CONCLUSION: Adding a filter to the Boussignac valve does not affect the delivered pressure but may variably increase the resistive load depending on the filter used. Clinical assessment suggests that FF-CPAP is a frugal solution to provide a ventilatory support and improve oxygenation to numerous patients suffering from AHRF in the context of a massive outbreak.

Reliability and limits of transport-ventilators to safely ventilate severe patients in special surge situations.

BACKGROUND: Intensive Care Units (ICU) have sometimes been overwhelmed by the surge of COVID-19 patients. Extending ICU capacity can be limited by the lack of air and oxygen pressure sources available. Transport ventilators requiring only one O2 source may be used in such places. OBJECTIVE: To evaluate the performances of four transport ventilators and an ICU ventilator in simulated severe respiratory conditions. MATERIALS AND METHODS: Two pneumatic transport ventilators, (Oxylog 3000, Draeger; Osiris 3, Air Liquide Medical Systems), two turbine transport ventilators (Elisee 350, ResMed; Monnal T60, Air Liquide Medical Systems) and an ICU ventilator (Engström Carestation-GE Healthcare) were evaluated on a Michigan test lung. We tested each ventilator with different set volumes (Vtset = 350, 450, 550 ml) and compliances (20 or 50 ml/cmH2O) and a resistance of 15 cmH2O/l/s based on values described in COVID-19 Acute Respiratory Distress Syndrome. Volume error (percentage of Vtset) with P0.1 of 4 cmH2O and trigger delay during assist-control ventilation simulating spontaneous breathing activity with P0.1 of 4 cmH2O and 8 cmH2O were measured. RESULTS: Grouping all conditions, the volume error was 2.9 ± 2.2% for Engström Carestation; 3.6 ± 3.9% for Osiris 3; 2.5 ± 2.1% for Oxylog 3000; 5.4 ± 2.7% for Monnal T60 and 8.8 ± 4.8% for Elisee 350. Grouping all conditions (P0.1 of 4 cmH2O and 8 cmH2O), trigger delay was 50 ± 11 ms, 71 ± 8 ms, 132 ± 22 ms, 60 ± 12 and 67 ± 6 ms for Engström Carestation, Osiris 3, Oxylog 3000, Monnal T60 and Elisee 350, respectively. CONCLUSIONS: In surge situations such as COVID-19 pandemic, transport ventilators may be used to accurately control delivered volumes in locations, where only oxygen pressure supply is available. Performances regarding triggering function are acceptable for three out of the four transport ventilators tested.

Assessment of rewarming methods in unplanned out-of-hospital births from a prospective cohort.

BACKGROUND: Mobile intensive care units frequently manage unplanned out-of-hospital births (UOHB). Rewarming methods during pre-hospital management of UOHB have not yet been compared. The aim was to compare rewarming methods used during pre-hospital management in a large prospective cohort of UOHB in France. METHODS: We analysed UOHB from the prospective AIE cohort from 25 prehospital emergency medical services in France. The primary outcome was the change in body temperature from arrival at scene to arrival at hospital. RESULTS: From 2011 to 2018, 1854 UOHB were recorded, of whom 520 were analysed. We found that using incubator care was the most effective rewarming method (+ 0.8 °C during transport), followed by the combination of plastic bag, skin-to-skin and cap (+ 0.2 °C). The associations plastic bag + cap and skin-to-skin + cap did not allow the newborn to be warmed up but rather to maintain initial temperature (+ 0.0 °C). The results of the multivariate model were consistent with these observations, with better rewarming with the use of an incubator. We also identified circumstances of increased risk of hypothermia according to classification and regression tree, like premature birth (< 37 weeks of gestation) and/or low outside temperature (< 8.4 °C). CONCLUSIONS: Using an incubator was the most effective rewarming method during pre-hospital management of UOHB in our French prospective cohort. Based on our model, in cases of term less than 37 weeks of gestation or between 37 and 40 weeks with a low outside temperature or initial hypothermia, using such a method would be preferred.

Unplanned out-of-hospital birth and risk factors of adverse perinatal outcome: findings from a prospective cohort.

BACKGROUND: In France, while most babies are delivered at hospital, emergency medical services (EMS) weekly manage calls for unplanned out-of-hospital births. The objective of our study was to describe neonatal morbidity and mortality, defined as death or neonatal intensive care unit hospitalization at Day 7, in a prospective multicentric cohort of unplanned out-of-hospital births. METHODS: We prospectively analyzed out-of-hospital births from 25 prehospital EMS units in France. The primary outcome was neonatal morbidity and mortality, and the secondary outcome was risk factors associated with neonatal morbidity and mortality. A univariate logistic regression was first made, followed by a multivariate logistic regression with backward selection. RESULTS: From October 2011 to August 2018, a total of 1670 unplanned out-of-hospital births were included. Of these, 1652 (99.2%) were singleton and 1537 (93.5%) had prenatal care. Maternal mean age of the study population was 30 ± 5.5 (range 15 to 48). The majority of women were multiparous, but 13% were nulliparous. Overall, 45.3% of these unplanned out-of-hospital births were medically-driven, either by phone during medical regulation (12.5%) or on scene by the prehospital emergency medical service units (32.9%). The prevalence of neonatal morbidity and mortality was 6.3% (n = 106) after an unplanned out-of-hospital birth (death before Day 7: n = 20; 1.2%). The multivariate logistic regression found that multiparity (adjusted Odds Ratio = 70.7 [4.7-1062]), prematurity (adjusted Odds Ratio = 6.7 [2.1-21.4]), maternal pathology (adjusted Odds Ratio = 2.8 [1.0-7.5]) and hypothermia (adjusted Odds Ratio = 2.8 [1.1-7.6]) were independent predictive factors of neonatal morbidity and mortality. CONCLUSIONS: Our study assessed for the first time risk factors for adverse perinatal outcome in a large and multicenter cohort of unplanned out-of-hospital births. We have to improve temperature management in the out-of-hospital field and future trials are required to investigate strategies to optimize newborns management in the prehospital area.

Fatal Myopericarditis Following an Influenza A (H3N2) Infection.

BACKGROUND Influenza viruses induce uncomplicated infections in most cases in individuals with no known predisposing factors. Acute febrile illness is generally limited to upper respiratory symptoms and several constitutional symptoms, including headache, lethargy, and myalgia. However, influenza A virus is a cause of severe morbidity and mortality worldwide. Some patients are at risk for serious and fatal complications. Cardiac involvement is a well-known condition, but, clinically apparent influenza myocarditis is not common. Few reports exist regarding recurrent fulminant influenza myocarditis. CASE REPORT We report here a fatal case of heart failure following myocarditis in a 14-year-old female who had seasonal flu symptoms but was otherwise healthy. H3N2 influenza virus infection was detected by molecular analyses of throat and nasal swabs, suggesting damage to myocardial cells caused directly by the virus. CONCLUSIONS Pericardial effusion myopericarditis may occur during influenza virus infection in young individuals, even those with no known predisposing factors. Physicians need to be aware that acute myopericarditis can be a fatal complication of recent influenza virus infection in all patients with instable hemodynamics. Early diagnosis and treatment could reduce, in some cases, the risk of severe cardiac events. However, this sudden and fatal outcome was difficult to predict in a healthy young female with no known risk factors.

How Ventilation Is Delivered During Cardiopulmonary Resuscitation: An International Survey.

BACKGROUND: Recommendations regarding ventilation during cardiopulmonary resuscitation (CPR) are based on a low level of scientific evidence. We hypothesized that practices about ventilation during CPR might be heterogeneous and may differ worldwide. To address this question, we surveyed physicians from several countries on their practices during CPR. METHODS: We used a Web-based opinion survey. Links to the survey were sent by e-mail newsletters and displayed on the Web sites of medical societies involved in CPR practice from December 2013 to March 2014. RESULTS: 1,328 surveys were opened, and 548 were completed (41%). Responses came from 54 countries, but 64% came from 6 countries. Responders were mostly physicians (89%). From this group, 97% declared following specific CPR guidelines. Regarding practices, 28% declared always or frequently adopting only continuous chest compressions without additional ventilation. With regard to mechanical chest compression devices, 38% responded that such devices were available to them; when used, 28% declared always or frequently experiencing problems with ventilation such as frequent alarms. During bag-mask ventilation in intubated patients, 18% declared stopping chest compression during insufflation, and 39% applied > 10 breaths/min, which conflicts with international CPR guidelines. When a ventilator was used, the volume controlled mode was the most common strategy cited, but there was heterogeneity regarding ventilator settings for PEEP, trigger, FIO2 , and breathing frequency. SpO2 and end-tidal CO2 were the 2 most monitored variables cited. CONCLUSIONS: Physicians indicated heterogeneous practices that often differ significantly from international CPR guidelines. This may reflect the low level of evidence and a lack of detailed recommendations concerning ventilation during CPR.

Management of severe acute pain in emergency settings: ketamine reduces morphine consumption.

OBJECTIVE: The aim of the study was to compare in emergency settings 2 analgesic regimens, morphine with ketamine (K group) or morphine with placebo (P group), for severe acute pain in trauma patients. METHODS: This was a prospective, multicenter, randomized, double-blind, clinical trial. Seventy-three trauma patients with a severe acute pain defined as a visual analog scale (VAS) score of at least 60/100 were enrolled. Patients in the K group received 0.2 mg x kg(-1) of intravenous ketamine over 10 minutes, and patients in the P group received isotonic sodium chloride solution. In both groups, patients were given an initial intravenous morphine injection of 0.1 mg x kg(-1), followed by 3 mg every 5 minutes. Efficient analgesia was defined as a VAS score not exceeding 30/100. The primary end points were morphine consumption and VAS at 30 minutes (T30). RESULTS: At T30, morphine consumption was significantly lower in the K group vs the P group, with 0.149 mg x kg(-1) (0.132-0.165) and 0.202 mg x kg(-1) (0.181-0.223), respectively (P < .001). The VAS score at T30 did not differ significantly between the 2 groups, with 34.1 (25.6-42.6) in the K group and 39.5 (32.4-46.6) in the P group (P = not significant). CONCLUSION: Ketamine was able to provide a morphine-sparing effect.

Evaluation of the ventilator-user interface of 2 new advanced compact transport ventilators.

BACKGROUND: Mechanical ventilation during patient transport frequently utilizes compact portable pneumatic ventilators that have limited ventilator-settings options. New advanced transport ventilators should yield quality improvements, but their user-friendliness needs to be tested. OBJECTIVE: To evaluate the ventilator-user interface of 2 new transport ventilators. METHODS: This was a 2-center descriptive study in which the ventilator-user interfaces of the Oxylog 3000 and Elisée 250 were compared by 20 French senior emergency physicians who were initially unfamiliar with these ventilators. Each physician carried out 15 tasks with each ventilator and then assigned each ventilator a satisfaction score. RESULTS: With the Elisée 250 the task success rate was significantly higher (85.6% vs 66.6% with the Oxylog 3000, p < 0.0001), and the total number of errors was lower (46 vs 113). The main errors were related to inspiratory flow settings with the Oxylog 3000 (31 errors), inspiratory-expiratory ratio settings with the Elisée 250 (11 errors), ventilation mode choice with the Oxylog 3000 (17 errors), trigger sensitivity setting with the Elisée 250 (16 errors) and the Oxylog 3000 (11 errors), and alarm range setting with the Oxylog 3000 (10 errors). The mean satisfaction score was significantly better with the Elisée 250 (81% +/- 7, range 64-92%) than with the Oxylog 3000 (66% +/- 10, range 49-87%) (p < 0.0001). CONCLUSIONS: The Elisée 250 ventilator-user interface was easier to use than that of the Oxylog 3000. The applicability of these results to other types of users will require further studies, but the types of errors found in our study might help future users.

Paradoxical reaction to epinephrine induced by beta-blockers in an anaphylactic shock induced by penicillin.

Increased risk of severe and resistant anaphylactic shock is a rare and not widely known adverse effect of beta-blocker treatment. It is illustrated in a case of refractory anaphylactic shock occurring in a 47-year-old woman who received beta-blockers. Actually, beta-blockers increase the release of anaphylactic mediators, decrease the cardiovascular compensatory changes to the anaphylactic shock and promote paradoxical reflex vagotonic effects when using epinephrine.

Details of the initial management of cardiac arrest occurring in the workplace in a French urban area.

INTRODUCTION: Our goal was to evaluate the details and management of cardiac arrest (CA) occurring in the working environment. MATERIALS AND METHODS: We conducted a 10-year retrospective study based on the medical records of the Garches mobile intensive care unit. CA occurring in the workplace ("Inside W." group) was matched with two CA outside the workplace ("Outside W." group), with regard to sex, age and year of occurrence. The Chain of Survival and prognosis factors were analysed in a bi-multivariate analysis. RESULTS: From 1993 to 2002, 72 CA were included in the "Inside W." group, with 79% arising from suspected cardiac aetiology (there was a similar proportion in the "Outside W." group). Some variables in the cardiac aetiology patients were higher in the "Inside W." group compared to the "Outside W." group (P < 0.05): early external chest compression [(ECC), 37%, n = 20 versus 16%, n = 16)] and ventricular fibrillation as initial recorded rhythm (40%, n = 33 versus 16%, n = 16). The proportion of use of automated external defibrillator (AED) was similar in the two groups. The workplace was not associated with a better outcome, with 9% patients discharged alive compared to 4% n = 6, P > 0.05. Early ECC and defibrillation attempted with an AED were associated with patients discharged alive from the intensive care unit in a multivariate analysis (P < 0.05), but not the workplace and cardiac aetiology. CONCLUSION: Although our study did not support that concept that the workplace was a safer place, there was a better chain of survival for CA applied within workplace settings. Basic Life Support teaching and installation of AEDs could be helpful, though further cost-effectiveness studies are needed.

Difficulties encountered by physicians in interpreting focused echocardiography using a pocket ultrasound machine in prehospital emergencies.

OBJECTIVE: Pocket ultrasound devices (PUDs) increase the scope of transthoracic echocardiography. We assessed the ability of emergency physicians (EPs) to obtain and interpret views using PUDs in prehospital emergencies. MATERIALS AND METHODS: Nine EPs underwent a 2-day training program focused on acquisition of four views and on evaluation of left ventricular function, right ventricular size, the inferior vena cava, and detection of pericardial effusion. Then, EPs used a PUD to perform transthoracic echocardiography in patients with shock or acute respiratory failure. The quality and interpretation of views were graded by an expert as not obtained/inadequate, adequate, or optimal. Agreement between the expert and the physicians was evaluated using Cohen's κ test. RESULTS: One hundred consecutive exams were evaluated in patients with shock or acute respiratory failure. Parasternal long-axis and short-axis views, and a subcostal view were not obtained or inadequate in 56, 54, and 54 patients, respectively. An apical four-chamber view was not obtained or inadequate in 33 patients. One, two, or three views were graded as adequate or optimal in 86, 65, and 35 patients. Agreement between physicians and experts for left ventricular systolic function, right ventricular size, and pericardial effusion was weak [κ 0.37 (0.17; 0.59), 0.27 (0.023; 0.53), and 0.33 (-0.008; 0.67)]. Agreement for inferior vena cava evaluation was very weak [0.13 (-0.17; 0.43)]. CONCLUSION: After a very short training program, echocardiography using a PUD in prehospital emergencies was feasible in half of patients. Acquisition of technical skills is reasonable, but accurate evaluation of cardiac function may require more extensive training.

'Boussignac' continuous positive airway pressure system: practical use in a prehospital medical care unit.

Continuous positive airway pressure in acute cardiogenic pulmonary edema is rarely used by prehospital emergency care units, because of the particular technical drawbacks of existing equipment. The aim of this one year prospective descriptive open study without a control group was to assess the technical feasibility of using the Boussignac continuous positive airway pressure system (Vygon) in a prehospital medical care service. Statistical comparisons were performed using Student's t-test or a Wilcoxon T-test. There were 57 decisions to use continuous positive airway pressure. Seven records were excluded. Four patients were intubated on the scene and six within one hour after hospital admission. The respiratory rate and transcutaneous oxygen saturation improved significantly for all of the other patients (Student's t-test P < 0.001). The Boussignac continuous positive airway pressure system has many advantages, including flexibility and pressure monitoring, lower oxygen consumption, and ease of use. These should allow this technique to be used more widely by prehospital teams.

Changes in reperfusion strategy over time for ST segment elevation myocardial infarction in the Greater Paris Area: results from the e-MUST Registry.

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.
