RÉSUMÉ

BACKGROUND: The benefit:risk profile of bivalirudin versus heparin anticoagulation in patients with non-ST-segment-elevation myocardial infarction undergoing percutaneous coronary intervention (PCI) is uncertain. Study-level meta-analyses lack granularity to provide conclusive answers. We sought to compare the outcomes of bivalirudin and heparin in patients with non-ST-segment-elevation myocardial infarction undergoing PCI. METHODS: We performed an individual patient data meta-analysis of patients with non-ST-segment-elevation myocardial infarction in all 5 trials that randomized ≥1000 patients with any myocardial infarction undergoing PCI to bivalirudin versus heparin (MATRIX [Minimizing Adverse Hemorrhagic Events by Transradial Access Site and Systemic Implementation of Angiox], VALIDATE-SWEDEHEART [Bivalirudin Versus Heparin in ST-Segment and Non-ST-Segment Elevation Myocardial Infarction in Patients on Modern Antiplatelet Therapy in the Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies Registry Trial], ISAR-REACT 4 [Intracoronary Stenting and Antithrombotic Regimen: Rapid Early Action for Coronary Treatment 4], ACUITY [Acute Catheterization and Urgent Intervention Triage Strategy], and BRIGHT [Bivalirudin in Acute Myocardial Infarction vs Heparin and GPI Plus Heparin Trial]). The primary effectiveness and safety end points were 30-day all-cause mortality and serious bleeding. RESULTS: A total of 12 155 patients were randomized: 6040 to bivalirudin (52.3% with a post-PCI bivalirudin infusion), and 6115 to heparin (53.2% with planned glycoprotein IIb/IIIa inhibitor use). Thirty-day mortality was not significantly different between bivalirudin and heparin (1.2% versus 1.1%; adjusted odds ratio, 1.24 [95% CI, 0.86-1.79]; P=0.25). Cardiac mortality, reinfarction, and stent thrombosis rates were also not significantly different. Bivalirudin reduced serious bleeding (both access site-related and non-access site-related) compared with heparin (3.3% versus 5.5%; adjusted odds ratio, 0.59; 95% CI, 0.48-0.72; P<0.0001). Outcomes were consistent regardless of use of a post-PCI bivalirudin infusion or routine lycoprotein IIb/IIIa inhibitor use with heparin and during 1-year follow-up. CONCLUSIONS: In patients with non-ST-segment-elevation myocardial infarction undergoing PCI, procedural anticoagulation with bivalirudin and heparin did not result in significantly different rates of mortality or ischemic events, including stent thrombosis and reinfarction. Bivalirudin reduced serious bleeding compared with heparin arising both from the access site and nonaccess sites.

RÉSUMÉ

BACKGROUND: ST-segment-elevation myocardial infarction (STEMI) guidelines recommend pharmaco-invasive treatment if timely primary percutaneous coronary intervention (PCI) is unavailable. Full-dose tenecteplase is associated with an increased risk of intracranial hemorrhage in older patients. Whether pharmaco-invasive treatment with half-dose tenecteplase is effective and safe in older patients with STEMI is unknown. METHODS: STREAM-2 (Strategic Reperfusion in Elderly Patients Early After Myocardial Infarction) was an investigator-initiated, open-label, randomized, multicenter study. Patients ≥60 years of age with ≥2 mm ST-segment elevation in 2 contiguous leads, unable to undergo primary PCI within 1 hour, were randomly assigned (2:1) to half-dose tenecteplase followed by coronary angiography and PCI (if indicated) 6 to 24 hours after randomization, or to primary PCI. Efficacy end points of primary interest were ST resolution and the 30-day composite of death, shock, heart failure, or reinfarction. Safety assessments included stroke and nonintracranial bleeding. RESULTS: Patients were assigned to pharmaco-invasive treatment (n=401) or primary PCI (n=203). Median times from randomization to tenecteplase or sheath insertion were 10 and 81 minutes, respectively. After last angiography, 85.2% of patients undergoing pharmaco-invasive treatment and 78.4% of patients undergoing primary PCI had ≥50% resolution of ST-segment elevation; their residual median sums of ST deviations were 4.5 versus 5.5 mm, respectively. Thrombolysis In Myocardial Infarction flow grade 3 at last angiography was ≈87% in both groups. The composite clinical end point occurred in 12.8% (51/400) of patients undergoing pharmaco-invasive treatment and 13.3% (27/203) of patients undergoing primary PCI (relative risk, 0.96 [95% CI, 0.62-1.48]). Six intracranial hemorrhages occurred in the pharmaco-invasive arm (1.5%): 3 were protocol violations (excess anticoagulation in 2 and uncontrolled hypertension in 1). No intracranial bleeding occurred in the primary PCI arm. The incidence of major nonintracranial bleeding was low in both groups (<1.5%). CONCLUSIONS: Halving the dose of tenecteplase in a pharmaco-invasive strategy in this early-presenting, older STEMI population was associated with electrocardiographic changes that were at least comparable to those after primary PCI. Similar clinical efficacy and angiographic end points occurred in both treatment groups. The risk of intracranial hemorrhage was higher with half-dose tenecteplase than with primary PCI. If timely PCI is unavailable, this pharmaco-invasive strategy is a reasonable alternative, provided that contraindications to fibrinolysis are observed and excess anticoagulation is avoided.

RÉSUMÉ

BACKGROUND/OBJECTIVES: The present study aimed at evaluating the impact on the early outcome of patients with ruptured intracranial aneurysms. METHODS: Our study prospectively included 26 consecutive patients with ruptured intracranial aneurysm managed at our institution in context of COVID-19 pandemic between March 1st, 2020 and April, 26th, 2020 (2020 group). A group control included other 28 consecutive patients managed at the same institution for the same disease in 2019, during the same time frame (2019 group). On admission, poor neurological status was defined as WFNS score >3. Severe radiological status was defined by the presence of intracerebral hematoma, or/and acute hydrocephalus requiring further EVD or/and the presence of vasospasm on presentation. Statistical analysis was performed to compare the 2 distinct groups. RESULTS: Rates of poor neurological presentation and severe radiological presentation on hospital admission were higher in the 2020 group (p = 0.01 and p = 0.02, respectively). The delayed hospital admission was 2.7 days in 2020 group and 0.75 days in 2019 group (p = 0.005). Therefore, vasospasm's rate on presentation was also higher in the 2020 group (p = 0.04). CONCLUSION: To our knowledge, this is one of the first studies demonstrating influence of the COVID-19 pandemic on patients with urgent and severe intracranial aneurysmal disease. In case of recurrent COVID-19 pandemic, educating the population concerning specific symptoms such as sudden headache, neurological deficit or even sudden chest pain should be emphasized.

RÉSUMÉ

RATIONALE, AIMS, AND OBJECTIVES: The human body is regulated by intrinsic factors which follow a 24-hour biological clock. Implications of a circadian rhythm in the out-of-hospital cardiac arrest (OHCA) are studied but the literature is not consistent. The main objective of our study was to identify temporal cluster of high or low incidence of OHCA occurrence during a day. METHODS: Multicentre comparative study based on the French national OHCA registry data between 2013 and 2017. After describing the population, the detection of significant temporal clusters of OHCA incidence was achieved using temporal scan statistics based on a Poisson model adjusted for age and gender. Then, comparisons between identified patients clusters and the rest of the population were performed. RESULTS: During the study, 37 163 medical OHCA victims were included. The temporal scan revealed a significant 3-hour high incidence temporal cluster between 8:00 am and 10:59 am (Relative R = 1.76, P < .001). In the identified cluster, OHCA occurred more out of the home with fewer witnesses, and advanced life support was less attempted in the cluster. No difference was observed on the return of spontaneous circulation, survival at hospital admission, and survival 30 days after the OHCA or at hospital discharge. CONCLUSIONS: We observed a three-hour morning high incidence peak of OHCA. This high incidence could be explained by different physiological changes in the morning. These changes are well known and the evidence of a morning peak of cardiovascular disease should enable medical teams to adapt care strategy and hospital organization.

RÉSUMÉ

BACKGROUND: The STREAM study demonstrated that a pharmaco-invasive strategy was at least as effective as primary PCI (pPCI) in patients presenting early with ST-elevation myocardial infarction (STEMI). The current trial is a response to the finding that reduced intracranial hemorrhage (ICH) in patients ≥75 years occurred after halving the dose of tenecteplase. Additionally, a subsequent analysis of full dose tenecteplase or alteplase in the Assessment of the Safety and Efficacy of a New Thrombolytic (ASSENT) trials demonstrated a steep increase in bleeding events beginning around the age of 60 years. METHODS: STREAM-2 will compare the efficacy and safety of a novel pharmaco-invasive strategy as compared to routine pPCI in STEMI patients ≥60 years presenting within 3 hours from symptom onset. In the pharmaco-invasive arm patients will receive half-dose tenecteplase, as soon as possible before transport to a PCI center. In the pPCI arm, patients will be treated according to optimal standard of care defined by local practice. The key criteria for efficacy will be the number of patients achieving ≥50% ST-segment resolution before and after PCI in lead with maximal ST elevation at baseline and the clinical endpoints of death, congestive heart failure, shock or re-infarction, rescue PCI and aborted myocardial infarction, both singularly and as a composite at 30 days. Key safety criteria are total stroke, ICH and major non-intracranial bleeds. Approximately 600 patients will be randomized (400 to pharmaco-invasive treatment and 200 to pPCI). An interim analysis is planned after 300 patients are enrolled to consider adapting the trial to include a larger sample size aimed at undertaking a formal confirmatory trial. DISCUSSION: The study will provide new insights aimed at establishing an effective and safer pharmaco-invasive treatment for the growing population of older STEMI patients who cannot undergo timely pPCI.

RÉSUMÉ

Hospitals play a critical role in providing communities with essential medical care during all types of disaster. Depending on their scope and nature, disasters can lead to a rapidly increasing service demand that can overwhelm the functional capacity and safety of hospitals and the healthcare system at large. Planning during the community outbreak of coronavirus disease 2019 (Covid-19) is critical for maintaining healthcare services during our response. This paper describes, besides general measures in times of a pandemic, also the necessary changes in the invasive diagnosis and treatment of patients presenting with different entities of acute coronary syndromes including structural adaptations (networks, spokes and hub centres) and therapeutic adjustments.

RÉSUMÉ

AIMS: ST-segment elevation myocardial infarction (STEMI) guidelines recommend primary percutaneous coronary intervention (pPCI) as the default reperfusion strategy when feasible ≤120 min of diagnostic ECG, and a pharmaco-invasive strategy otherwise. There is, however, a lack of direct evidence to support the guidelines, and in real-world situations, pPCI is often performed beyond recommended timelines. To assess 5-year outcomes according to timing of pPCI (timely vs. late) compared with a pharmaco-invasive strategy (fibrinolysis with referral to PCI centre). METHODS AND RESULTS: The French registry of Acute ST-elevation and non-ST-elevation Myocardial Infarction (FAST-MI) programme consists of nationwide observational surveys consecutively recruiting patients admitted for acute myocardial infarction every 5 years. Among the 4250 STEMI patients in the 2005 and 2010 cohorts, those with reperfusion therapy and onset-to-first call time <12 h (n = 2942) were included. Outcomes at 5 years were compared according to type of reperfusion strategy and timing of pPCI, using Cox multivariable analyses and propensity score matching. Among those, 1288 (54%) patients had timely pPCI (≤120 min from ECG), 830 (28%) late pPCI (>120 min), and 824 (28%) intravenous fibrinolysis. Five-year survival was higher with a pharmaco-invasive strategy (89.8%) compared with late pPCI [79.5%; adjusted hazard ratio (HR) 1.51; 1.13-2.02] and similar to timely pPCI (88.2%, adjusted HR 1.02; 0.75-1.38). Concordant results were observed in propensity score-matched cohorts and for event-free survival. CONCLUSION: A substantial proportion of patients have pPCI beyond recommended timelines. As foreseen by the guidelines, these patients have poorer 5-year outcomes, compared with a pharmaco-invasive strategy.

RÉSUMÉ

Chest pain and acute dyspnoea are frequent causes of emergency medical services activation. The pre-hospital management of these conditions is heterogeneous across different regions of the world and Europe, as a consequence of the variety of emergency medical services and absence of specific practical guidelines. This position paper focuses on the practical aspects of the pre-hospital treatment on board and transfer of patients taken in charge by emergency medical services for chest pain and dyspnoea of suspected cardiac aetiology after the initial assessment and diagnostic work-up. The objective of the paper is to provide guidance, based on evidence, where available, or on experts' opinions, for all emergency medical services' health providers involved in the pre-hospital management of acute cardiovascular care.

RÉSUMÉ

BACKGROUND: Individual randomized controlled trials (RCTs) of periprocedural anticoagulation with bivalirudin versus heparin during percutaneous coronary intervention (PCI) have reported conflicting results. Study-level meta-analyses lack granularity to adjust for confounders, explore heterogeneity, or identify subgroups that may particularly benefit or be harmed. OBJECTIVE: To overcome these limitations, we sought to develop an individual patient-data pooled database of RCTs comparing bivalirudin versus heparin. METHODS: We conducted a systematic review to identify RCTs in which ≥1,000 patients with acute myocardial infarction (AMI) undergoing PCI were randomized to bivalirudin versus heparin. RESULTS: From 738 identified studies, 8 RCTs met the prespecified criteria. The principal investigators of each study agreed to provide patient-level data. The data were pooled and checked for accuracy against trial publications, with discrepancies addressed by consulting with the trialists. Consensus-based definitions were created to resolve differing antithrombotic, procedural, and outcome definitions. The project required 3.5 years to complete, and the final database includes 27,409 patients (13,346 randomized to bivalirudin and 14,063 randomized to heparin). CONCLUSION: We have created a large individual patient database of bivalirudin versus heparin RCTs in patients with AMI undergoing PCI. This endeavor may help identify the optimal periprocedural anticoagulation regimen for patient groups with different relative risks of adverse ischemic versus bleeding events, including those with ST-segment and non-ST-segment elevation MI, radial versus femoral access, use of a prolonged bivalirudin infusion or glycoprotein inhibitors, and others. Adherence to standardized techniques and rigorous validation processes should increase confidence in the accuracy and robustness of the results.

RÉSUMÉ

Comprehensive stroke care is an interdisciplinary challenge. Close collaboration of cardiologists and stroke physicians is critical to ensure optimum utilisation of short- and long-term care and preventive measures in patients with stroke. Risk factor management is an important strategy that requires cardiologic involvement for primary and secondary stroke prevention. Treatment of stroke generally is led by stroke physicians, yet cardiologists need to be integrated care providers in stroke units to address all cardiovascular aspects of acute stroke care, including arrhythmia management, blood pressure control, elevated levels of cardiac troponins, valvular disease/endocarditis, and the general management of cardiovascular comorbidities. Despite substantial progress in stroke research and clinical care has been achieved, relevant gaps in clinical evidence remain and cause uncertainties in best practice for treatment and prevention of stroke. The Cardiovascular Round Table of the European Society of Cardiology together with the European Society of Cardiology Council on Stroke in cooperation with the European Stroke Organisation and partners from related scientific societies, regulatory authorities and industry conveyed a two-day workshop to discuss current and emerging concepts and apparent gaps in stroke care, including risk factor management, acute diagnostics, treatments and complications, and operational/logistic issues for health care systems and integrated networks. Joint initiatives of cardiologists and stroke physicians are needed in research and clinical care to target unresolved interdisciplinary problems and to promote the best possible outcomes for patients with stroke.

RÉSUMÉ

Importance: Therapeutic hypothermia may increase survival with good neurologic outcome after cardiac arrest. Trans-nasal evaporative cooling is a method used to induce cooling, primarily of the brain, during cardiopulmonary resuscitation (ie, intra-arrest). Objective: To determine whether prehospital trans-nasal evaporative intra-arrest cooling improves survival with good neurologic outcome compared with cooling initiated after hospital arrival. Design, Setting, and Participants: The PRINCESS trial was an investigator-initiated, randomized, clinical, international multicenter study with blinded assessment of the outcome, performed by emergency medical services in 7 European countries from July 2010 to January 2018, with final follow-up on April 29, 2018. In total, 677 patients with bystander-witnessed out-of-hospital cardiac arrest were enrolled. Interventions: Patients were randomly assigned to receive trans-nasal evaporative intra-arrest cooling (n = 343) or standard care (n = 334). Patients admitted to the hospital in both groups received systemic therapeutic hypothermia at 32°C to 34°C for 24 hours. Main Outcomes and Measures: The primary outcome was survival with good neurologic outcome, defined as Cerebral Performance Category (CPC) 1-2, at 90 days. Secondary outcomes were survival at 90 days and time to reach core body temperature less than 34°C. Results: Among the 677 randomized patients (median age, 65 years; 172 [25%] women), 671 completed the trial. Median time to core temperature less than 34°C was 105 minutes in the intervention group vs 182 minutes in the control group (P < .001). The number of patients with CPC 1-2 at 90 days was 56 of 337 (16.6%) in the intervention cooling group vs 45 of 334 (13.5%) in the control group (difference, 3.1% [95% CI, -2.3% to 8.5%]; relative risk [RR], 1.23 [95% CI, 0.86-1.72]; P = .25). In the intervention group, 60 of 337 patients (17.8%) were alive at 90 days vs 52 of 334 (15.6%) in the control group (difference, 2.2% [95% CI, -3.4% to 7.9%]; RR, 1.14 [95% CI, 0.81-1.57]; P = .44). Minor nosebleed was the most common device-related adverse event, reported in 45 of 337 patients (13%) in the intervention group. The adverse event rate within 7 days was similar between groups. Conclusions and Relevance: Among patients with out-of-hospital cardiac arrest, trans-nasal evaporative intra-arrest cooling compared with usual care did not result in a statistically significant improvement in survival with good neurologic outcome at 90 days.

RÉSUMÉ

BACKGROUND: In the ACCOAST (A Comparison of Prasugrel at PCI or Time of Diagnosis of Non-ST Elevation Myocardial Infarction) trial, the prasugrel pre-treatment strategy versus placebo was associated with excess bleeding complications and no improved ischemic outcome in non-ST-segment elevation myocardial infarction (MI). Whether patients with the longest pre-treatment duration had an ischemic benefit is unknown. OBJECTIVES: This pre-specified analysis of the ACCOAST trial aimed to assess the effect of pre-treatment duration with prasugrel (time from randomization to angiography) on outcomes. METHODS: Within the 4,033 patients randomized in the ACCOAST trial, pre-treatment duration was available in 4,001 patients (99.2%). The population of the trial was divided into quartiles of pre-treatment duration (0.1 to 2.5 h, 2.5 to 3.9 h, 3.9 to 13.6 h, and >13.6 h) with an evaluation of the primary efficacy endpoint of cardiovascular death, MI, stroke, urgent revascularization or glycoprotein IIb/IIIa inhibitor bailout use. Secondary efficacy outcomes including cardiovascular death, MI, or stroke; all-cause death; stent thrombosis and safety outcomes (all coronary artery bypass graft [CABG] or non-CABG TIMI [Thrombolysis In Myocardial Infarction] major bleeding) were also evaluated at 7 days. RESULTS: The primary efficacy outcome of cardiovascular death, MI, stroke, urgent revascularization or glycoprotein IIb/IIIa inhibitor bailout use did not differ between the quartiles of pre-treatment duration in the trial population (p = 0.17 for interaction). None of the secondary efficacy outcomes were found to be dependent on pre-treatment duration. The safety outcome of all CABG or non-CABG TIMI major bleeding did not differ between the quartiles of pre-treatment duration (p = 0.37 for interaction). CONCLUSIONS: In non-ST-segment elevation MI patients, the excess risk of bleeding and the absence of ischemic benefit were consistent across the quartiles of increasing duration of prasugrel pre-treatment. (A Comparison of Prasugrel at PCI or Time of Diagnosis of Non-ST Elevation Myocardial Infarction [ACCOAST]; NCT01015287).

RÉSUMÉ

Background The optimal timing of administration of dual antiplatelet therapy (DAPT) in acute ST-segment-elevation myocardial infarction patients is debated. Clinical trials have failed to demonstrate the superiority of pretreatment with P2Y12 inhibitors in ST-segment-elevation myocardial infarction, but they were not designed to assess hard clinical end points. We used data from the FAST-MI (French Registry on Acute ST-Segment-Elevation or Non-ST-Segment-Elevation Myocardial Infarction) cohorts to determine 1-year survival and in-hospital outcomes in patients receiving DAPT, comparing prehospital versus in-hospital administration. Methods and Results The FAST-MI program collects extensive data on patients admitted in France for acute myocardial infarction over a 1-month period every 5 years since 2005. For the present analysis, 3548 patients with ST-segment-elevation myocardial infarction ≤12 hours from symptom onset, transported by physician-staffed emergency medical system ambulances, not treated with intravenous fibrinolysis, and receiving DAPT were included, of whom 44% received DAPT in the ambulance. The primary end point was 1-year survival as assessed by multivariate Cox analysis and propensity score analysis. In-hospital bleeding and ischemic complications were also analyzed. Adjusted in-hospital mortality was numerically but not significantly lower in patients with prehospital DAPT. There were no differences in in-hospital bleeding complications. Fully-adjusted hazard ratio for 1-year death in patients with prehospital versus in-hospital DAPT was 0.69 (95% CI, 0.51-0.92; P=0.011), and propensity score-adjusted hazard ratio was 0.55 (95% CI, 0.41-0.73; P=0.001) in the whole population. In the propensity score-matched cohorts (360 patients each), 1-year survival was 93.9% in patients with prehospital versus 90.3% in those with in-hospital DAPT (hazard ratio, 0.62; 95% CI, 0.36-1.05; P=0.077). Results were consistent in subgroups, including by year of survey, age, presence of out-of-hospital cardiac arrest, morphine use, and type of P2Y12 inhibitor used. Conclusions In these cohorts of ST-segment-elevation myocardial infarction patients considered for primary percutaneous coronary intervention, prehospital administration of DAPT was associated with higher 1-year survival and no increase in in-hospital bleeding complications. The magnitude of the decrease in 1-year mortality, however, may suggest the persistence of some degree of residual confounding. Clinical Trial Registration: URL: https://www.clinicaltrials.gov .

RÉSUMÉ

BACKGROUND: There is growing evidence in the literature that brief contact interventions (BCIs) might be reliable suicide prevention strategies. OBJECTIVE: To assess the effectiveness of a decision-making algorithm for suicide prevention (ALGOS) combining existing BCIs in reducing suicide reattempts in patients discharged after a suicide attempt. METHODS: A randomized, multicenter, controlled, parallel trial was conducted in 23 hospitals. The study was conducted from January 26, 2010, to February 28, 2013. People who had made a suicide attempt were randomly assigned to either the intervention group (ALGOS) or the control group. The primary outcome was the rate of participants who reattempted suicide (fatal or not) within the 6-month study period. RESULTS: 1,040 patients were recruited. After 6 months, 58 participants in the intervention group (12.8%) reattempted suicide compared with 77 (17.2%) in the control group. The difference between groups (4.4%; 95% CI, -0.7% to 9.0%) was not significant (complete-case analysis, P = .059). CONCLUSIONS: These results may help researchers better integrate BCIs into routine health care and provide new insights concerning personalized suicide prevention strategies.

RÉSUMÉ

AIMS: The STREAM study randomly assigned ST-elevation myocardial infarction (STEMI) patients to receive a pharmacoinvasive versus primary percutaneous coronary intervention reperfusion strategy. We assessed whether there was an association between outcomes based on randomisation at a community hospital versus a prehospital location. METHODS/RESULTS: Community hospital patients (358/1866 (19.2%)) were compared to prehospital patients and their outcomes categorised into pharmacoinvasive according to their treatment assignment. Compared to prehospital patients, community hospital patients had more diabetes (17.8% vs. 11.5%, P=0.001), higher Killip Class >1 (9.4% vs. 5.0%, P=0.002) and thrombolysis in myocardial infarction risk scores ⩾5 (18.2% vs. 12.4%, P=0.005). The 30-day primary endpoint (death, shock, congestive heart failure and re-infarction) for community hospital patients was 14.9% versus 13.2% for prehospital patients ( P=0.403). Community hospital pharmacoinvasive patients tended to receive less rescue (35.1% vs. 42.8%, P=0.062); when deployed their rescue was delayed 43 minutes. Community hospital patients undergoing primary percutaneous coronary intervention experienced a delay of 31 minutes versus prehospital patients. Pharmacoinvasive patients receiving scheduled angiography from a community hospital and prehospital patients had comparable times to angiography (17.7 vs. 18.7 hours) and low event rates (6.2% vs. 8.0%). Although the interaction between randomisation location and treatment received on the primary endpoint was not significant ( Pinteraction=0.065) those pharmacoinvasive patients requiring rescue from community hospitals had worse outcomes than prehospital rescue patients (odds ratio 2.28, 95% confidence interval 1.16-4.49). CONCLUSION: Within STREAM, STEMI patients randomly assigned at community hospitals had a higher baseline risk but similar outcomes compared to those studied prehospital patients irrespective of successful pharmacoinvasive therapy or primary percutaneous coronary intervention. However, worse outcomes in the pharmacoinvasive patients requiring rescue in community hospitals emphasises their need for immediate transfer to a percutaneous coronary intervention-capable hospital.

RÉSUMÉ

BACKGROUND: ST-segment-elevation myocardial infarction (STEMI) and non-ST-segment-elevation myocardial infarction (NSTEMI) management has evolved considerably over the past 2 decades. Little information on mortality trends in the most recent years is available. We assessed trends in characteristics, treatments, and outcomes for acute myocardial infarction in France between 1995 and 2015. METHODS: We used data from 5 one-month registries, conducted 5 years apart, from 1995 to 2015, including 14 423 patients with acute myocardial infarction (59% STEMI) admitted to cardiac intensive care units in metropolitan France. RESULTS: From 1995 to 2015, mean age decreased from 66±14 to 63±14 years in patients with STEMI; it remained stable (68±14 years) in patients with NSTEMI, whereas diabetes mellitus, obesity, and hypertension increased. At the acute stage, intended primary percutaneous coronary intervention increased from 12% (1995) to 76% (2015) in patients with STEMI. In patients with NSTEMI, percutaneous coronary intervention ≤72 hours from admission increased from 9% (1995) to 60% (2015). Six-month mortality consistently decreased in patients with STEMI from 17.2% in 1995 to 6.9% in 2010 and 5.3% in 2015; it decreased from 17.2% to 6.9% in 2010 and 6.3% in 2015 in patients with NSTEMI. Mortality still decreased after 2010 in patients with STEMI without reperfusion therapy, whereas no further mortality gain was found in patients with STEMI with reperfusion therapy or in patients with NSTEMI, whether or not they were treated with percutaneous coronary intervention. CONCLUSIONS: Over the past 20 years, 6-month mortality after acute myocardial infarction has decreased considerably for patients with STEMI and NSTEMI. Mortality figures continued to decline in patients with STEMI until 2015, whereas mortality in patients with NSTEMI appears stable since 2010.

RÉSUMÉ

BACKGROUND: The FAST-MI programme, consisting of 1-month surveys of patients admitted to hospital for acute myocardial infarction (AMI) in France, has run since 2005. AIM: To gather data on the characteristics, management and outcomes of patients hospitalized for AMI at the end of 2015 in France and to provide comparisons with the previous surveys. METHODS: Consecutive adults with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment-elevation myocardial infarction (NSTEMI) with symptom onset≤48hours were included over a 1-month period, with a possible extension of recruitment for 1 additional month. Patients with AMI following cardiovascular procedures were excluded. In all, 204 centres participated in the survey (114 community hospitals, 40 academic, 48 private clinics, 2 army hospitals), representing 78% of French centres managing AMI patients. Inclusion started from 5 October 2015. Data were collected on-site from source files by external research technicians, using an electronic case record form with automatic quality checks. Centralized biology was organized in voluntary centres to collect RNA and DNA samples, serum and stools. Long-term follow-up was organized centrally with interrogation of municipal registry offices, physicians and by direct contact with the patients or their families. RESULTS: A total of 5291 patients were included over the entire recruitment period, with 3813 included during the first month (STEMI: 49%, NSTEMI: 51%). Mean age was 66±14 years, 29% were≥75 years of age, 28% were women; 80% presented with typical chest pain. In STEMI patients, 6% received intravenous fibrinolysis and 71% underwent primary PCI. The hospital death rate was 2.7% (STEMI: 2.8%, NSTEMI: 2.5%). CONCLUSIONS: Recruitment was in line with expectations and the first data show that management has continued to evolve since the 2010 survey, with continued improvement in hospital outcomes.

RÉSUMÉ

Chest pain units are defined as organizational short stay units with specific management protocols designed to facilitate and optimize the diagnosis of patients presenting with chest pain in the emergency department. The present document is intended to standardize and facilitate the installation of chest pain units nearby to the emergency department or as an integral part of the emergency department. Recommendations on organizational structure, physical and technical requirements and on disease management are presented. More standardized installation and implementation of chest pain units will enhance the quality of chest pain units and improve the quality of care of our chest pain patients.
