Bleeding and thrombotic risk of different antiplatelet regimens posttranscatheter edge-to-edge mitral valve repair in patients with an indication for oral anticoagulation: Results from an all-comers national registry.

BACKGROUND: Evidence-based recommendations for antithrombotic treatment in patients who have an indication for oral anticoagulation (OAC) after transcatheter edge-to-edge mitral valve repair (TEER) are lacking. AIMS: To compare bleeding and thrombotic risk for different antithrombotic regimens post-TEER with MitraClip in an unselected population with the need for OACs. METHODS: Bleeding and thrombotic complications (stroke and myocardial infarction) up to 3 months after TEER with mitraclip were evaluated in 322 consecutive pts with an indication for OACs. These endpoints were defined by the Mitral Valve Academic Research Consortium criteria and were compared between two antithrombotic regimens: single antithrombotic therapy with OAC (single ATT) and double/triple ATT with a combination of OAC and aspirin and/or clopidogrel (combined ATT). RESULTS: Collectively, 108 (34%) patients received single ATT, 203 (63%) received double ATT and 11 (3%) received triple ATT. Bleeding events occurred in 67 patients (20.9%), with access site related events being the most frequent cause (37%). Bleeding complications were observed more frequently in the combined ATT group than in the single ATT group: 24% versus 14% [p = 0.03, adjusted RR: 0.55 (0.3-0.98)]. Within the combined group, the bleeding risk was 23% in the double ATT and 45% in the triple ATT group. Thrombotic complications occurred in only three patients (0.9%), and all belonged to the combined ATT group. CONCLUSIONS: In patients with an indication for OACs, withholding of antiplatelet therapy post-TEER with Mitraclip was associated with a 45% reduction in bleeding and without a signal of increased thrombotic risk.

Reproducibility and predictive value of a simple novel method to measure atrial fibrillation cycle length in persistent atrial fibrillation - FARS-AF study.

INTRODUCTION: Different methods are used for atrial fibrillation (AF) cycle length (CL) measurement with variable results. Previous studies of pulmonary vein (PV) CL measurement showed contradictory results on predicting PV isolation (PVI) efficacy. A novel simple method of measuring the average of 10 consecutive Fastest Atrial Repetitive Similar morphology signal (FARS10 )-CL to characterize local atrial activity rate was evaluated prospectively. METHODS: The intra-observer reproducibility of FARS10 -CL and traditional AF-CL measurement of continuously fragmented coronary sinus (CS) signals were tested. We prospectively enrolled 100 consecutive patients (62 ± 10 years, 72% male) undergoing wide antral PVI only ablation for persistent AF, measured PV-FARS10 -CLs, and evaluated long-term outcome. RESULTS: The Kendall area correlation between repeated traditional AF-CL measurements was -0.006 and between repeated FARS10 -CL measurements in the right and left atrial appendages, CS and PVs were 0.944, 0.859, 0.882, 0.675-0.955, respectively. Patients with recurrent atrial tachyarrhythmia had significantly longer fastest PV-FARS10 -CL (172 ± 41 vs. 156 ± 41 ms, p = .047). Patients with high burden of spontaneous low-voltage zone (LVZ) had significantly longer fastest PV-FARS10 -CL. Freedom from recurrent tachyarrhythmia at 24 months was 85% versus 59% in patients with fastest PV-FARS10 -CL ≤ 140 versus >140 ms, p = .0018, respectively. In multivariable analysis fastest PV-FARS10 -CL ≤ 140 ms was the only significant predictor of freedom from recurrent tachyarrhythmia. CONCLUSIONS: FARS10 -CL measurements have a high reproducibility in contrast to traditional AF-CL measurement of continuously fragmented CS signals. Patients with high burden of LVZ have longer fastest PV-FARS10 -CLs. Fastest PV-FARS10 -CL ≤ 140 ms is associated with a high success of wide antral PVI-only ablation approach in persistent AF.

Regression of Q waves and clinical outcomes following primary PCI in anterior STEMI.

BACKGROUND: Pathological Q waves are correlated with infarct size, and Q-wave regression is associated with left ventricular ejection fraction improvement. There are limited data regarding the association of Q-wave regression and clinical outcomes. Our main objective was to assess the association of pathological Q wave evolution after reperfusion with clinical outcomes after anterior STEMI. METHODS: Standard 12-lead electrocardiograms (ECGs) were recorded in 780 anterior STEMI patients treated with primary percutaneous coronary intervention (PCI) from the CIRCUS trial. ECGs were recorded before and 90 min following PCI, as well as at hospitalization discharge and 12 months of follow-up. The number of classic ECG criteria Q waves was scored for each ECG. Patients were classified in the Q wave regression group if they had regression of at least one Q wave between the post-PCI, the discharge and/or one year ECGs. Patients were classified in the Q wave persistent group if they had the same number or greater between the post-PCI, the discharge and/or 1 and one year ECGs. All-cause death and heart failure events were assessed for all patients at one year. RESULTS: There were 323(43%) patients with persistent Q waves (PQ group), 378(49%) patients with Q wave regression (RQ group) and 60(8%) patients with non-Q wave MI (NQ group). Infarct size as measured by the peak creatine kinase was significantly greater in the PQ group compared to the RQ and NQ groups (4633 ±â€¯2784 IU/l vs. 3814 ±â€¯2595 IU/l vs. 1733 ±â€¯1583 IU/l respectively, p < 0.0001). At one year, there were 22 deaths (7%) in the PQ-group, 15 (4%) in the RQ-group and none in the NQ-group (p = 0.04). There was a 4-fold increase in the risk of death or heart failure in the PQ compared to the NQ group (HR 4.7 [1.1; 19.3]; p = 0.03), but there was no significant difference between NQ and RQ groups (HR 3.3 [0.8; 13.8]; p = 0.09). CONCLUSION: In a population of anterior STEMI patients, persistent Q waves defined according to the classic ECG criteria after reperfusion was associated with a 4-fold increase in the risk of heart failure or death compared to non-Q-wave MI, while Q-wave regression was associated with significantly lower risk of events.

Importance of infarct size versus other variables for clinical outcomes after PPCI in STEMI patients.

Despite promising experimental studies and encouraging proof-of-concept clinical trials, interventions aimed at limiting infarct size have failed to improve clinical outcomes in patients with ST-elevation myocardial infarction (STEMI). Our objective was to examine whether variables (cardiovascular risk factors, comorbidities, post-procedural variables, cotreatments) might be associated with clinical outcomes in STEMI patients independently from infarct size reduction. The present study was based on a post hoc analysis of the CIRCUS trial database (Clinicaltrials.gov NCT01502774) that assessed the clinical benefit of a single intravenous bolus of cyclosporine in 969 patients with anterior STEMI. Since cyclosporine had no detectable effect on clinical outcomes as well as on any measured variable, we here considered the whole study population as one group. Multivariate analysis was performed to address the respective weight of infarct size and variables in clinical outcomes. Multivariate analysis revealed that several variables (including gender, hypertension, renal dysfunction, TIMI flow grade post-PCI < 3, and treatment administered after PCI with betablockers and angiotensin-converting enzyme inhibitors) had per se a significant influence on the occurrence of [death or hospitalization for heart failure] at 1 year. The relative weight of infarct size and variables on the composite endpoint of [death or hospitalization for heart failure] at 1 year was 18% and 82%, respectively. Several variables contribute strongly to the clinical outcomes of STEMI patients suggesting that cardioprotective strategy might not only focus on infarct size reduction.

Clinically significant bleeding with low-dose rivaroxaban versus aspirin, in addition to P2Y12 inhibition, in acute coronary syndromes (GEMINI-ACS-1): a double-blind, multicentre, randomised trial.

BACKGROUND: Dual antiplatelet therapy (DAPT), aspirin plus a P2Y12 inhibitor, is the standard antithrombotic treatment following acute coronary syndromes. The factor Xa inhibitor rivaroxaban reduced mortality and ischaemic events when added to DAPT, but caused increased bleeding. The safety of a dual pathway antithrombotic therapy approach combining low-dose rivaroxaban (in place of aspirin) with a P2Y12 inhibitor has not been assesssed in acute coronary syndromes. We aimed to assess rivaroxaban 2·5 mg twice daily versus aspirin 100 mg daily, in addition to clopidogrel or ticagrelor (chosen at investigator discretion before randomisation), for patients with acute coronary syndromes started within 10 days after presentation and continued for 6-12 months. METHODS: In this double-blind, multicentre, randomised trial (GEMINI-ACS-1) done at 371 clinical centres in 21 countries, eligible patients were older than 18 years with unstable angina, non-ST segment elevation myocardial infarction (NSTEMI) or ST segment elevation myocardial infarction (STEMI), with positive cardiac biomarkers and either ischaemic electrocardiographic changes or an atherosclerotic culprit lesion identified during angiography. Participants were randomly assigned (1:1) within 10 days after admission for the index acute coronary syndromes event to either aspirin or rivaroxaban based on a computer-generated randomisation schedule. Randomisation was balanced by using randomly permuted blocks with size of four and was stratified based on the background P2Y12 inhibitor (clopidogrel or ticagrelor) intended to be used at the time of randomisation. Investigators and patients were masked to treatment assignment. Patients received a minimum of 180 days of double-blind treatment with rivaroxaban 2·5 mg twice daily or aspirin 100 mg daily. The choice of clopidogrel or ticagrelor during trial conduct was not randomised and was based on investigator preference. The primary endpoint was thrombolysis in myocardial infarction (TIMI) clinically significant bleeding not related to coronary artery bypass grafting (CABG; major, minor, or requiring medical attention) up to day 390. Primary analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT02293395. FINDINGS: Between April 22, 2015, and Oct 14, 2016, 3037 patients with acute coronary syndromes were randomly assigned; 1518 to receive aspirin and 1519 to receive rivaroxaban. 1704 patients (56%) were in the ticagrelor and 1333 (44%) in the clopidogrel strata. Median duration of treatment was 291 days (IQR 239-354). TIMI non-CABG clinically significant bleeding was similar with rivaroxaban versus aspirin therapy (total 154 patients [5%]; 80 participants [5%] of 1519 vs 74 participants [5%] of 1518; HR 1·09 [95% CI 0·80-1·50]; p=0·5840). INTERPRETATION: A dual pathway antithrombotic therapy approach combining low-dose rivaroxaban with a P2Y12 inhibitor for the treatment of patients with acute coronary syndromes had similar risk of clinically significant bleeding as aspirin and a P2Y12 inhibitor. A larger, adequately powered trial would be required to definitively assess the efficacy and safety of this approach. FUNDING: Janssen Research & Development and Bayer AG.

Cyclosporine before PCI in Patients with Acute Myocardial Infarction.

BACKGROUND: Experimental and clinical evidence suggests that cyclosporine may attenuate reperfusion injury and reduce myocardial infarct size. We aimed to test whether cyclosporine would improve clinical outcomes and prevent adverse left ventricular remodeling. METHODS: In a multicenter, double-blind, randomized trial, we assigned 970 patients with an acute anterior ST-segment elevation myocardial infarction (STEMI) who were undergoing percutaneous coronary intervention (PCI) within 12 hours after symptom onset and who had complete occlusion of the culprit coronary artery to receive a bolus injection of cyclosporine (administered intravenously at a dose of 2.5 mg per kilogram of body weight) or matching placebo before coronary recanalization. The primary outcome was a composite of death from any cause, worsening of heart failure during the initial hospitalization, rehospitalization for heart failure, or adverse left ventricular remodeling at 1 year. Adverse left ventricular remodeling was defined as an increase of 15% or more in the left ventricular end-diastolic volume. RESULTS: A total of 395 patients in the cyclosporine group and 396 in the placebo group received the assigned study drug and had data that could be evaluated for the primary outcome at 1 year. The rate of the primary outcome was 59.0% in the cyclosporine group and 58.1% in the control group (odds ratio, 1.04; 95% confidence interval [CI], 0.78 to 1.39; P=0.77). Cyclosporine did not reduce the incidence of the separate clinical components of the primary outcome or other events, including recurrent infarction, unstable angina, and stroke. No significant difference in the safety profile was observed between the two treatment groups. CONCLUSIONS: In patients with anterior STEMI who had been referred for primary PCI, intravenous cyclosporine did not result in better clinical outcomes than those with placebo and did not prevent adverse left ventricular remodeling at 1 year.

Incidence and Significance of Spontaneous ST Segment Re-elevation After Reperfused Anterior Acute Myocardial Infarction　- Relationship With Infarct Size, Adverse Remodeling, and Events at 1 Year.

BACKGROUND: Up to 25% of patients with ST elevation myocardial infarction (STEMI) have ST segment re-elevation after initial regression post-reperfusion and there are few data regarding its prognostic significance.Methods and Results:A standard 12-lead electrocardiogram (ECG) was recorded in 662 patients with anterior STEMI referred for primary percutaneous coronary intervention (PPCI). ECGs were recorded 60-90 min after PPCI and at discharge. ST segment re-elevation was defined as a ≥0.1-mV increase in STMax between the post-PPCI and discharge ECGs. Infarct size (assessed as creatine kinase [CK] peak), echocardiography at baseline and follow-up, and all-cause death and heart failure events at 1 year were assessed. In all, 128 patients (19%) had ST segment re-elevation. There was no difference between patients with and without re-elevation in infarct size (CK peak [mean±SD] 4,231±2,656 vs. 3,993±2,819 IU/L; P=0.402), left ventricular (LV) ejection fraction (50.7±11.6% vs. 52.2±10.8%; P=0.186), LV adverse remodeling (20.1±38.9% vs. 18.3±30.9%; P=0.631), or all-cause mortality and heart failure events (22 [19.8%] vs. 106 [19.2%]; P=0.887) at 1 year. CONCLUSIONS: Among anterior STEMI patients treated by PPCI, ST segment re-elevation was present in 19% and was not associated with increased infarct size or major adverse events at 1 year.

Care Pathway Effect on In-Hospital Care for ST-Elevation Myocardial Infarction.

OBJECTIVES: To study the care pathway effect on the percentage of patients with ST-elevation myocardial infarction -(STEMI) receiving timely coronary reperfusion and the percentage of STEMI patients receiving optimal secondary prevention. METHODS: A care pathway was implemented by the Collaborative Model for Achieving Breakthrough Improvement. One pre-intervention and 2 post-intervention audits included all adult STEMI patients admitted within 24 h after onset and eligible for reperfusion. Adjusted (hospital random intercepts and controls for transfer and out-of-office admission) differences in composite outcomes were analyzed by a multilevel logistic regression. RESULTS: Significant improvements in intervals between the first medical contact (FMC) to percutaneous coronary intervention (PCI) and between the door to PCI were shown between post-intervention audit II and post-intervention audit I. Secondary prevention significantly deteriorated at post-intervention audit I but improved significantly between both post-intervention audits. Six out of nine outcomes were significantly poorer in the case of transfer. The interval from FMC to PCI was significantly poorer for patients admitted during out-of-office hours. CONCLUSIONS: After care pathway implementation, composite outcomes improved for in-hospital STEMI care. Collaborative efforts exploited heterogeneity in performance between hospitals. Iterative and incremental care pathway implementation maximized performance improvement.

Climate and environmental triggers of acute myocardial infarction.

Over the past few decades, a growing body of epidemiological and clinical evidence has led to heightened concerns about the potential short- and long-term deleterious effects of the environment on cardiovascular health, including the risk for acute myocardial infarction (AMI). This review highlights the increased risk of AMI caused by exposure to air pollution and cold temperatures. These factors should be considered modifiable risk factors in the prevention of cardiovascular disease. The current body of knowledge about the biological mechanisms linking environmental changes to atherothrombotic events and the impact of climate change on cardiovascular health are discussed. Finally, recommendations for prevention and public policy are presented.

Quality assessment in percutaneous coronary interventions: the QERMID Belgian PCI registry.

BACKGROUND: The recent increase in the number of interventional cathlabs that followed a moratorium of several years has resulted in an abrupt increase in the number of PCI and a dilution of the experience per centre and per operator. METHODS: Based on data extracted from the national "Quality Oriented Electronic Registration of Medical Implant Devices" (QERMID) database, we compared the characteristics and outcome of patients treated in 2015 in the 21 newly (<3 years) approved PCI centres with those of patients treated in the 28 historical PCI centres. RESULTS: The proportion of acute coronary syndromes was slightly higher in new than in historical centres (48% vs. 44%; p < 0.01) but few differences in co-morbidities were observed. Considering separately the patients treated for an acute coronary syndrome or for stable ischaemia, no significant difference in the overall in-hospital or 30-days mortality and in the proportion of same week bypass surgery was observed between newly approved and historical centres. In a substantial proportion (39%) of patients treated for stable angina or silent ischaemia, no test confirming the presence of ischaemia before PCI is reported, without significant difference between new and historical centres. CONCLUSIONS: Pending the limitations of the QERMID database, including a limited dataset and the absence of systematic on-site monitoring, no significant difference in the rate of major complications was identified between new and historical Belgian PCI centres.

Cardiac sarcoidosis: a diagnostic and therapeutic challenge.

OBJECTIVE: Cardiac involvement in sarcoidosis can present in various ways, with atrioventricular (AV) block and ventricular arrhythmias being the most common signs. Because of initial non-specific findings, diagnosis can be a challenge. Very few data can support treatment decisions as cardiac manifestations of this systemic disorder are rare. METHODS AND RESULTS: We reviewed current guidelines, cohort studies, and expert opinions concerning diagnosis and treatment of cardiac sarcoidosis. CONCLUSIONS: Longitudinal follow-up studies are necessary to improve the diagnostic process and risk stratification of cardiac sarcoidosis. The optimal dose of steroids, indications for internal cardioverter-defibrillator (ICD), and technique and optimal timing of ablation are still under debate.

Comparison of radial access versus femoral access with the use of a vascular closure device for the prevention of vascular complications and mortality after percutaneous coronary intervention.

BACKGROUND: Radial access (RA) and vascular closure devices (VCD) have been shown to be superior to transfemoral access (TFA) with regard to the prevention of vascular complications after percutaneous coronary intervention (PCI). OBJECTIVE: The present study evaluates whether RA is associated with less vascular complications and a lower mortality than VCD. METHODS: A total of 6999 consecutive PCI patients were studied through a single-centre prospective registry from January 2011 to August 2015. RA was applied in 1385 patients (20%), VCDs with Angio-Seal were implanted in 2145 patients (30%) and manual compression of TFA was performed in 3468 patients (50%). RESULTS: RA and VCD patients had comparable baseline risk profiles. The overall vascular complication rate was 2.0% (n = 137) and was composed of false aneurysms (n = 85), clinically relevant haematomas (n = 27), arteriovenous fistulas (n = 12), arterial occlusions (n = 11) and local infections (n = 2). Vascular complications occurred in 0.6% of RA patients, 1.8% of VCD patients and 2.6% of TFA patients (p < .01). In-hospital mortality was 0.8% in RA patients, 0.8% in VCD patients and 3.8% in TFA patients (p < .01). In a multivariate logistic regression model, RA, compared to VCD, was found to be independently associated with a lower rate of vascular complications (OR: 0.34, 95% CI: 0.16-0.75), but not with lower mortality rates (OR: 1.20, 95% CI: 0.51-2.85). CONCLUSION: In this large all-comers PCI population, the radial approach, compared to the femoral approach with VCD use (Angio-Seal), was independently associated with a reduction of vascular complications, but not with lower mortality rates.

Failed Downregulation of Circulating MicroRNA-155 in the Early Phase after ST Elevation Myocardial Infarction Is Associated with Adverse Left Ventricular Remodeling.

BACKGROUND: MicroRNA are noncoding RNA that have a significant role in both inflammatory and cardiovascular diseases. AIMS: We aimed to assess whether the inflammation-related microRNA-155 is associated with the development of adverse left ventricular (LV) remodeling following ST elevation myocardial infarction (STEMI). METHODS: Peripheral blood samples were collected in the inflammatory (day 2), proliferative (day 5), and maturation phases (6 months) after STEMI (n = 20). Granulocytes, monocytes, and lymphocytes were enumerated with flow cytometry. The changes in LV volumes were assessed with 3-D echocardiography on day 1 and after 6 months. Adverse remodeling was defined as a >20% increase in end-diastolic volume. Healthy subjects were recruited as controls. RESULTS: MicroRNA-155 measured on day 5 correlated positively with the relative change in end-diastolic volume (ρ = 0.490, p = 0.028). MicroRNA-155 (day 5) was significantly higher in patients with compared to patients without adverse LV remodeling. The expression level was similar in healthy subjects (n = 8) and in patients with LV remodeling. There was a positive correlation between microRNA-155 and the amount of monocytes (day 5, ρ = 0.463, p = 0.046). CONCLUSION: Impaired downregulation of microRNA-155 during the second phase of the post- STEMI inflammatory response is a determinant of the development of adverse LV remodeling.

Summary of 2016 ESC guidelines on heart failure, atrial fibrillation, dyslipidaemia and cardiovascular prevention.

During the ESC congress in September 2016 in Rome, the new ESC guidelines were presented and are now available on the ESC website ( http://www.escardio.org/guidelines ). The new guidelines cover management recommendations on following cardiovascular items: Heart failure, atrial fibrillation, dyslipidemia and cardiovascular prevention. The present document gives a summary of these guidelines and highlights the most important recommendations and changes in the management of these diseases. It will help to increase awareness about the new guidelines and may stimulate to consult the full document for specific items. Ultimately, the authors hope that this document will enhance implementation of new ESC guidelines in daily clinical practice.

Quality assessment in Belgian ST elevation myocardial infarction patients: results from the Belgian STEMI database.

The present report describes the quality of care, including in hospital mortality for more than 22.000 STEMI patients admitted in 60 Belgian hospitals for the period 2008-2016. We found a strong increase in the use of primary PCI over time, particularly for patients that were admitted first in a non-PCI capable hospital, reaching a penetration rate of >95%. The transition of thrombolysis to transfer for pPCI in the setting of a STEMI network was, however, associated with an increase of the proportion of patients with prolonged (>120 min) diagnosis-to-balloon time (from 16 to 22%), suggesting still suboptimal interhospital transfer. The in-hospital mortality of the total study population was 6.5%. For non-cardiac arrest patients in-hospital mortality decreased from 5.1% to 3.7%, while it increased for cardiac arrest patients from 29 to 37%. The observation that quality indicators (QI's), such as modalities and timing of reperfusion therapy, were associated with lower levels of mortality, underscores the potential of QIs for STEMI to improve care and reduce unwarranted variation and premature death from STEMI.

Key interventions and quality indicators for quality improvement of STEMI care: a RAND Delphi survey.

OBJECTIVE: Identification, selection and validation of key interventions and quality indicators for improvement of in hospital quality of care for ST-elevated myocardial infarction (STEMI) patients. METHODS AND RESULTS: A structured literature review was followed by a RAND Delphi Survey. A purposively selected multidisciplinary expert panel of cardiologists, nurse managers and quality managers selected and validated key interventions and quality indicators prior for quality improvement for STEMI. First, 34 experts (76% response rate) individually assessed the appropriateness of items to quality improvement on a nine point Likert scale. Twenty-seven key interventions, 16 quality indicators at patient level and 27 quality indicators at STEMI care programme level were selected. Eighteen additional items were suggested. Experts received personal feedback, benchmarking their score with group results (response rate, mean, median and content validity index). Consequently, 32 experts (71% response rate) openly discussed items with an item-content validity index above 75%. By consensus, the expert panel validated a final set of 25 key interventions, 13 quality indicators at patient level and 20 quality indicators at care programme level prior for improvement of in hospital care for STEMI. CONCLUSIONS: A structured literature review and multidisciplinary expertise was combined to validate a set of key interventions and quality indicators prior for improvement of care for STEMI. The results allow researchers and hospital staff to evaluate and support quality improvement interventions in a large cohort within the context of a health care system.

One-year and longer dual antiplatelet therapy after an acute coronary syndrome: a Belgian position paper.

Acute coronary syndrome patients receive DAPT up to one year after their initial event. Exceptions to the guideline-recommended one-year rule, however, are not uncommon. The reasoning behind shorter treatments, such as unacceptable bleeding risk or urgent surgery, should be well documented in the patient's charts and discharge letter. Based on recent evidence, patients at high risk for repetitive events should continue on low-dose ticagrelor without a significant interruption at one year and indefinitely in the absence of excess bleeding risk. As there is currently no reimbursement, policy makers and insurers should be made aware of the continuing risk and unmet clinical need in this patient population. Nevertheless, many unsolved questions need to be answered, both through additional analyses from recent trials such as PEGASUS-TIMI 54 or DAPT, as well as new carefully designed clinical studies.

Pre-hospital management of acute coronary syndrome patients in Belgium and Luxembourg and other Western European countries.

OBJECTIVES: This sub-analysis of the EPICOR study describes pre-hospital care (PHC) patterns in Belgium, Luxembourg (Belux) and Western European (WEU) countries (Finland, Norway, Denmark, the Netherlands, UK, Belgium, Luxembourg, Spain, France, Italy, Greece and Germany. METHODS AND RESULTS: EPICOR (NCT01171404) is multinational, observational study comprising patients with acute coronary syndrome hospitalized within 24h of symptoms onset, diagnosed with ST-segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI) or unstable angina (UA). Of the 325 WEU centres, 37 were in Belgium and 1 in Luxembourg. PHC was defined as pre-hospital ECG and/or pre-hospital medication (PHM). 504 Belux and 6,119 WEU patients were enrolled. Of the WEU patients 51.5% received PHC and 28.1% PHM, compared to 27.6% and 11.3% of the Belux patients. These differences were observed in both STEMI and UA/NSTEMI patients. In Belux, the most frequent PHM was acetylsalicylic acid (53 patients); only 1 patient received thrombolytics. The median time from symptoms onset to ECG was longer for Belux (2.8 h) than for WEU patients (2.4 h). PHC shortened this time by almost 1.5h. Belux patients with PHC had a shorter median time between symptoms onset and first medical attention (FMA) than WEU patients (1.0 vs 1.3 h). Only 34.7% of Belux patients with pre-hospital ECG and with time from FMA to ECG available had ECG within 10 minutes of FMA, as recommended by the European Society of Cardiology. CONCLUSIONS: In Belux, diagnostic ECG is delayed compared to WEU, despite the short time to FMA. Few patients undergo ECG within the recommended period, indicating room for improvement.

Reperfusion therapy for ST elevation acute myocardial infarction 2010/2011: current status in 37 ESC countries.

AIMS: Primary percutaneous coronary intervention (PPCI) is the preferred reperfusion therapy in ST-elevation myocardial infarction (STEMI). We conducted this study to evaluate the contemporary status on the use and type of reperfusion therapy in patients admitted with STEMI in the European Society of Cardiology (ESC) member countries. METHODS AND RESULTS: A cross-sectional descriptive study based on aggregated country-level data on the use of reperfusion therapy in patients admitted with STEMI during 2010 or 2011. Thirty-seven ESC countries were able to provide data from existing national or regional registries. In countries where no such registries exist, data were based on best expert estimates. Data were collected on the use of STEMI reperfusion treatment and mortality, the numbers of cardiologists, and the availability of PPCI facilities in each country. Our survey provides a brief data summary of the degree of variation in reperfusion therapy across Europe. The number of PPCI procedures varied between countries, ranging from 23 to 884 per million inhabitants. Primary percutaneous coronary intervention and thrombolysis were the dominant reperfusion strategy in 33 and 4 countries, respectively. The mean population served by a single PPCI centre with a 24-h service 7 days a week ranged from 31 300 inhabitants per centre to 6 533 000 inhabitants per centre. Twenty-seven of the total 37 countries participated in a former survey from 2007, and major increases in PPCI utilization were observed in 13 of these countries. CONCLUSION: Large variations in reperfusion treatment are still present across Europe. Countries in Eastern and Southern Europe reported that a substantial number of STEMI patients are not receiving any reperfusion therapy. Implementation of the best reperfusion therapy as recommended in the guidelines should be encouraged.
