BACKGROUND: Venous thromboembolism (VTE), encompassing both deep vein thrombosis (DVT) and pulmonary embolism (PE), is a leading cause of morbidity and mortality worldwide. METHODS: GARFIELD-VTE is a prospective, non-interventional observational study of real-world treatment practices. We aimed to capture the 36-month clinical outcomes of 10,679 patients with objectively confirmed VTE enrolled between May 2014 and January 2017 from 415 sites in 28 countries. FINDINGS: A total of 6582 (61.6 %) patients had DVT alone, 4097 (38.4 %) had PE ± DVT. At baseline, 98.1 % of patients received anticoagulation (AC) with or without other modalities of therapy. The proportion of patients on AC therapy decreased over time: 87.6 % at 3 months, 73.0 % at 6 months, 54.2 % at 12 months and 42.0 % at 36 months. At 12-months follow-up, the incidences (95 % confidence interval [CI]) of all-cause mortality, recurrent VTE and major bleeding were 6.5 (7.0-8.1), 5.4 (4.9-5.9) and 2.7 (2.4-3.0) per 100 person-years, respectively. At 36-months, these decreased to 4.4 (4.2-4.7), 3.5 (3.2-2.7) and 1.4 (1.3-1.6) per 100 person-years, respectively. Over 36-months, the rate of all-cause mortality and major bleeds were highest in patients treated with parenteral therapy (PAR) versus oral anti-coagulants (OAC) and no OAC, and the rate of recurrent VTE was highest in patients on no OAC versus those on PAR and OAC. The most frequent cause of death after 36-month follow-up was cancer (n = 565, 48.6 %), followed by cardiac (n = 94, 8.1 %), and VTE (n = 38, 3.2 %). Most recurrent VTE events were DVT alone (n = 564, 63.3 %), with the remainder PE, (n = 236, 27.3 %), or PE in combination with DVT (n = 63, 7.3 %). INTERPRETATION: GARFIELD-VTE provides a global perspective of anticoagulation patterns and highlights the accumulation of events within the first 12 months after diagnosis. These findings may help identify treatment gaps for subsequent interventions to improve patient outcomes in this patient population. ispartof: THROMBOSIS RESEARCH vol:222 pages:31-39 ispartof: location:United States status: published

Background: Oral activated factor XI (FXIa) inhibitors may modulate coagulation to prevent thromboembolic events without substantially increasing bleeding. We explored the pharmacodynamics, safety, and efficacy of the oral FXIa inhibitor asundexian for secondary prevention after acute myocardial infarction (MI). Methods: We randomized 1601 patients with recent acute MI to oral asundexian 10, 20, or 50 mg or placebo once daily for 6 to 12 months in a double-blind, placebo-controlled, phase 2, dose-ranging trial. Patients were randomized within 5 days of their qualifying MI and received dual antiplatelet therapy with aspirin plus a P2Y12 inhibitor. The effect of asundexian on FXIa inhibition was assessed at 4 weeks. The prespecified main safety outcome was Bleeding Academic Research Consortium type 2, 3, or 5 bleeding comparing all pooled asundexian doses with placebo. The prespecified efficacy outcome was a composite of cardiovascular death, MI, stroke, or stent thrombosis comparing pooled asundexian 20 and 50 mg doses with placebo. Results: The median age was 68 years, 23% of participants were women, 51% had ST-segment–elevation MI, 80% were treated with aspirin plus ticagrelor or prasugrel, and 99% underwent percutaneous coronary intervention before randomization. Asundexian caused dose-related inhibition of FXIa activity, with 50 mg resulting in >90% inhibition. Over a median follow-up of 368 days, the main safety outcome occurred in 30 (7.6%), 32 (8.1%), 42 (10.5%), and 36 (9.0%) patients receiving asundexian 10 mg, 20 mg, or 50 mg, or placebo, respectively (pooled asundexian versus placebo: hazard ratio, 0.98 [90% CI, 0.71–1.35]). The efficacy outcome occurred in 27 (6.8%), 24 (6.0%), 22 (5.5%), and 22 (5.5%) patients assigned asundexian 10 mg, 20 mg, or 50 mg, or placebo, respectively (pooled asundexian 20 and 50 mg versus placebo: hazard ratio, 1.05 [90% CI, 0.69–1.61]). Conclusions: In patients with recent acute MI, 3 doses of asundexian, when added to aspirin plus a P2Y12 inhibitor, resulted in dose-dependent, near-complete inhibition of FXIa activity without a significant increase in bleeding and a low rate of ischemic events. These data support the investigation of asundexian at a dose of 50 mg daily in an adequately powered clinical trial of patients who experienced acute MI.

Aim: To investigate the value of prospective in-hospital registry data and the impact of an infectious endocarditis heart team approach (IEHT) on improvement in quality of care and monitor outcomes in hospitalized patients with IE. Methods: Between December 2014 and the end of 2019, 160 patients were hospitalized in one centre with the definite diagnosis of infectious endocarditis (IE) and entered in a prospective registry. From 2017, an IEHT was introduced. Propensity score matching was used to assess the impact of an IEHT approach on clinical outcomes. Results: Median age was 72.5 y (62.75–80.00), diabetes was present in 33.1%, chronic kidney disease in 27.5%, COPD in 17.5%, and a history of ischaemic heart disease in 30.6%. Prosthetic valve IE was observed in 43.8% and device-related IE in 16.9% of patients. Staphylococcus (37.5%) was the most frequent pathogen followed by streptococcus (24.4%) and enterococcus (23.1%). Overall, 30-day and 1-year mortality were 19.4% and 37.5%, respectively. The introduction of prospective data collection and IE heart team was associated with a trend towards reduction of adjusted 1-year mortality (26.5% IEHT vs. 41.2% controls, p = 0.0699). An IEHT clinical decision-making approach was independently associated with a shorter length of stay (p = 0.04). Conclusions: Use of a prospective registry of IE coupled with a heart team approach was associated with more efficient patient management and a trend towards lower mortality. Prospective data collection and dedicated IEHT have the potential to improve patient care and clinical outcomes.

BACKGROUND: Compared to functional testing, coronary computed tomography angiography (CTA) improves clinical outcomes in patients with suspected coronary artery disease (CAD). This is thought to be the result of an increased prescription of preventive medical therapy (statins and aspirin) when relying on a CTA imaging strategy. We compared the rate of statins prescription in a patient cohort assessed either with coronary CTA or exercise testing, and evaluated the agreement on medication prescriptions. METHODS: Consecutive patients who underwent coronary CTA and exercise test for suspected CAD were included. Four clinical cardiologists independently analysed each case based on clinical information and the result of either coronary CTA or exercise test. For each case, treatment strategy and prescription were recorded while blinded to the results of the other cardiac test. Treatment strategy was reassessed using the alternative imaging modality three weeks after the first evaluation. RESULTS: A total of 113 patients were included. Mean age was 56.7±11.5 years, 52% were males and diabetes were present in 6%. Coronary CTA showed an obstructive epicardial stenosis in 21.4% and any type of atherosclerotic plaque in 54.2%. Functional testing identified ischemia in 9.1%. The use of coronary CTA resulted in higher number of statin (64.9% vs. 44.5%, P

Aims To assess the adherence to established quality indicators (QIs) for ST-elevation myocardial infarction (STEMI) at the hospital-network level and its relation to outcome. Methods and results The data of 7774 STEMI patients admitted to 32 STEMI networks during the period 2014–18 were extracted from the Belgian STEMI database. Five QIs [primary percutaneous coronary intervention use, diagnosis-to-balloon time (DiaTB) Conclusion Among established STEMI networks, the time delay between diagnosis and treatment was the most variable and the most relevant prognostic QI, underscoring the importance of assessing quality of care throughout the whole network.

Background: Familial hypercholesterolaemia (FH) is underdiagnosed in most countries. We report our first experience from a national pilot project of cascade screening in relatives of FH patients. Methodology: Participating specialists recruited consecutive index patients (IP) with Dutch Lipid Clinic Network (DLCN) score ≥6. After informed consent, the relatives were visited by the nurses to collect relevant clinical data and perform blood sampling for lipid profile measurement. FH diagnosis in the relatives was based on the DLCN and/or MEDPED FH (Make-Early-Diagnosis-to-Prevent-Early-Deaths-in-FH) criteria. Results: In a period of 18 months, a total of 127 IP (90 with definite FH and 37 with probable FH) were enrolled in 15 centres. Out of the 270 relatives visited by the nurses, 105 were suspected of having FH: 31 with DCLN score >8, 33 with DLCN score 5-8 and 41 with MEDPED FH criteria. In a post-hoc analysis, another set of MEDPED FH criteria established in the Netherlands and adapted to Belgium allowed to detect FH in 51 additional relatives. Conclusion: In a country with no national FH screening program, our pilot project demonstrated that implementing a simple phenotypical FH cascade screening strategy using the collaboration of motivated specialists and two nurses, allowed to diagnose FH in 127 index patients and an additional 105 of their relatives over the two-year period. Newly developed MEDPED FH cut-offs, easily applicable by a nurse with a single blood sample, might further improve the sensitivity of detecting FH within families., SCOPUS: ar.j, info:eu-repo/semantics/published

Aim: Cardiac arrest is a common complication of ST elevation myocardial infarction and is associated with high mortality. We evaluated whether vulnerability to cardiac arrest follows a circadian rhythm and whether it is related to specific patient characteristics. Methods: A total of 24,164 ST elevation myocardial infarction patients who were admitted to 60 Belgian hospitals between 2008–2017 were analysed. The proportion of patients with cardiac arrest before initiation of reperfusion therapy was calculated for different time periods (hour of the day, months, seasons) and related to patient characteristics using stepwise logistic regression analysis. Results: Cardiac arrest occurred in 10.8% of the ST elevation myocardial infarction patients at a median of 65 min (interquartile range 33–138 min) after onset of pain. ST elevation myocardial infarction patients with cardiac arrest showed a biphasic pattern with one peak in the morning and one peak in the late afternoon. Multivariate analysis identified the following independent factors associated with cardiac arrest: cardiogenic shock (odds ratio=28), left bundle branch block (odds ratio=3.7), short ( Conclusion: In the present study population, cardiac arrest in ST elevation myocardial infarction showed an atypical circadian rhythm with not only a morning peak but also a second peak in the late afternoon, suggesting that cardiac arrest and ST elevation myocardial infarction triggers are, at least partially, different. In addition, specific patient characteristics, such as short ischaemic period, cardiogenic shock and left bundle branch block, increase the vulnerability to cardiac arrest.

Background Parenteral anticoagulants and vitamin K antagonists (VKAs) have constituted the cornerstone of venous thromboembolism (VTE) treatment. Meanwhile, direct oral anticoagulants (DOACs) provide physicians with an alternative. The Global Anticoagulant Registry in the FIELD (GARFIELD)-VTE observes real-world treatment practices. Objectives Describe initial anticoagulation (AC) treatment patterns in VTE patients who received parenteral AC, VKAs, and/or DOACs within ±30 days of diagnosis. Methods VTE patients were categorized into parenteral AC only, parenteral AC with transition to VKA, VKA only, parenteral AC with transition to DOAC, and DOAC only. Results A total of 9647 patients were initiated on AC treatment alone. 4781 (49.6%) patients received DOACs ± parenteral ACs; 3187 (33.0%), VKA ± parenteral ACs; and 1679 (17.4%) parenteral ACs alone. Rivaroxaban was the most frequently used DOAC (79.4%). DOACs were more frequently used in North America/Australia (58.1%), Europe (52.2%), and Asia (47.6%) than in Latin America (29.7%) and the Middle East/South Africa (32.5%). In patients with suspected VTE, most received parenteral AC monotherapy (67.7%). Patients with deep vein thrombosis were more likely to receive DOACs alone than those with pulmonary embolism with or without deep vein thrombosis (36.2% vs 25.9%). Active cancer patients received parenteral AC alone (58.9%), with 25.5% receiving DOAC ± parenteral AC and 12.8% parenteral AC and VKA. A total of 46.5% of pregnant patients received parenteral AC monotherapy, 34.0% were treated with VKA ± parenteral AC, and 19.5% received a DOAC (± parenteral AC). Conclusion AC treatment patterns vary by patient population, geographic region and site of VTE. Guidelines for AC therapy are not always adhered to.

Background and aims: Familial hypercholesterolaemia (FH) is an autosomal dominant lipoprotein disorder characterized by significant elevation of low-density lipoprotein cholesterol (LDL-C) and markedly increased risk of premature cardiovascular disease (CVD). Because of the very high coronary artery disease risk associated with this condition, the prevalence of FH among patients admitted for CVD outmatches many times the prevalence in the general population. Awareness of this disease is crucial for recognizing FH in the aftermath of a hospitalization of a patient with CVD, and also represents a unique opportunity to identify relatives of the index patient, who are unaware they have FH. This article aims to describe a feasible strategy to facilitate the detection and management of FH among patients hospitalized for CVD. Methods: A multidisciplinary national panel of lipidologists, cardiologists, endocrinologists and cardio-geneticists developed a three-step diagnostic algorithm, each step including three key aspects of diagnosis, treatment and family care. Results: A sequence of tasks was generated, starting with the process of suspecting FH amongst affected patients admitted for CVD, treating them to LDL-C target, finally culminating in extensive cascade-screening for FH in their family. Conceptually, the pathway is broken down into 3 phases to provide the treating physicians with a time-efficient chain of priorities. Conclusions: We emphasize the need for optimal collaboration between the various actors, starting with a “vigilant doctor” who actively develops the capability or framework to recognize potential FH patients, continuing with an “FH specialist” and finally involving the patient himself as ”FH ambassador” to approach his/her family and facilitate cascade screening and subsequent treatment of relatives., SCOPUS: ar.j, info:eu-repo/semantics/published

Aims: The relationship between the predictive performance of the TIMI risk score for STEMI and gender has not been evaluated in the setting of primary PCI (pPCI). Here, we compared in-hospital mortality and predictive performance of the TIMI risk score between Belgian women and men undergoing pPCI. Methods and results: In-hospital mortality was analysed in 8,073 (1,920 [23.8%] female and 6,153 [76.2%] male patients) consecutive pPCI-treated STEMI patients, included in the prospective, observational Belgian STEMI registry (January 2007 to February 2011). A multivariable logistic regression model, including TIMI risk score variables and gender, evaluated differences in in-hospital mortality between men and women. The predictive performance of the TIMI risk score according to gender was evaluated in terms of discrimination and calibration. Mortality rates for TIMI scores in women and men were compared. Female patients were older, had more comorbidities and longer ischaemic times. Crude in-hospital mortality was 10.1% in women vs. 4.9% in men (OR 2.2; 95% CI: 1.82-2.66, p

Objectives: Emergency medical services play a key role in the recognition and treatment of ST-segment elevation myocardial infarction (STEMI). This study evaluates the effect of emergency medical services use on adherence to reperfusion therapy guidelines in Belgian STEMI patients and on in-hospital mortality. Methods: The mode of admission with against without emergency medical services was associated with baseline risk profile, reperfusion modalities and in-hospital mortality in 5692 consecutive STEMI patients from 2012 to 2014. Results: A total of 3896 STEMI patients (68%) were transported to the hospital by emergency medical services, and 1796 patients (32%) arrived at the hospital using their own transport (self-referral). Emergency medical services patients were older than self-referral patients (64 vs. 62 years) and more frequently presented with cardiac arrest (14% vs. 5%) and with cardiogenic shock (10% vs. 4%). Emergency medical services patients received primary percutaneous coronary intervention more often (95% vs. 91%, P

Aim To define the long-term outcome of patients presenting with acute coronary syndrome [ST-segment elevation myocardial infarction (STEMI), and non-STEMI and unstable angina acute coronary syndrome (ACS) without biomarker elevation] and to test the hypothesis that the GRACE (Global Registry of Acute Coronary Events) risk score predicts mortality and death/MI at 5 years. Methods and results In the GRACE long-term study, UK and Belgian centres prospectively recruited and followed ACS patients for a median of 5 years (1797 days). Primary outcome events: deaths, cardiovascular deaths (CVDs) and MIs. Secondary events: stroke and re-hospitalization for ACS. There were 736 deaths, 19.8% (482 CVDs, 13%) and 347 (9.3%) MIs (>24 h), 261 strokes (7.7%), and 452 (17%) subsequent revascularizations. Rehospitalization was common: average 1.6 per patient; 31.2% had >1 admission, 9.2% had 5+ admissions. These events were despite high rates of guideline indicated therapies. The GRACE score was highly predictive of all-cause death, CVD, and CVD/MI at 5 years (death: χ2 likelihood ratio 632; Wald 709.9, P < 0.0001, C -statistic 0.77; for CVD C -statistic 0.75, P < 0.0001; CVD/MI C -statistic 0.70, P < 0.0001). Compared with the low-risk GRACE stratum (ESC Guideline criteria), those with intermediate [hazard ratio (HR) 2.14, 95% CI 1.63, 2.81] and those with high-risk (HR 6.36, 95% CI 4.95, 8.16) had two- and six-fold higher risk of later death (Cox proportional hazard). A landmark analysis after 6 months confirmed that the GRACE score predicted long-term death (χ2 likelihood ratio 265.4; Wald 289.5, P < 0.0001). Although in-hospital rates of death and MI are higher following STEMI, the cumulative rates of death (and CVD) were not different, by class of ACS, over the duration of follow-up (Wilcoxon = 1.5597, df = 1, P = 0.21). At 5 years after STEMI 269/1403 (19%) died; after non-STEMI 262/1170 (22%) after unstable angina (UA) 149/850 (17%). Two-thirds (68%) of STEMI deaths occurred after initial hospital discharge, but this was 86% for non-STEMI and 97% for UA. Conclusion The GRACE risk score predicts early and 5 year death and CVD/MI. Five year morbidity and mortality are as high in patients following non-ST MI and UA as seen following STEMI. Their morbidity burden is high (MI, stroke, readmissions) and the substantial late mortality in non-STE ACS is under-recognized. The findings highlight the importance of pursuing novel approaches to diminish long-term risk.

Acute heart attacks are a major healthcare problem with continuing high mortality and morbidity rates. The major goal in the treatment of acute myocardial infarction (AMI) is the rapid restoration of blood flow and myocardial perfusion in the infarct zone. This can be achieved by either a pharmacological approach (fibrinolysis) or by a mechanical approach (immediate coronary angiography and coronary dilatation of the occluded infarct artery, the so-called primary percutaneous coronary intervention or PCI). A timely application of reperfusion therapy has been shown to influence favourably shortand long-term patient outcome. Data from several large registries have, however, shown that reperfusion therapy is insufficiently implemented in many countries1. A considerable number of patients with ST-segment elevation myocardial infarction (STEMI) do not receive any reperfusion therapy, for a wide variety of reasons, despite its availability and the absence of any contra-indication. In addition, for patients who do have access to reperfusion, preor in-hospital delays can adversely influence the outcome. In this context, a policy conference was organised in Brussels on 30 September 2006 to review the status quo of reperfusion strategies, taking into account existing guidelines and data from registries. In addition, strategies to optimize reperfusion therapy were discussed in regional meetings during 2007. This policy statement presents a summary of the topics discussed at the policy conference and subsequent regional meetings and also refers to the recently published European Society of Cardiology (ESC) guidelines on the management of acute myocardial infarction in patients presenting with persistent ST-segment elevation. This document has been reviewed and approved by the board members of the Belgian Society of Cardiology and its working groups on acute cardiology and interventional cardiology.

ObjectivesThis study was designed to investigate: 1) relationships between serum ST2 levels and hemodynamic/neurohormonal variables; 2) myocardial ST2 production; and the 3) expression of ST2, membrane-anchored ST2L, and its ligand, interleukin (IL)-33, in myocardium, endothelium, and leukocytes from patients with left ventricular (LV) pressure overload and congestive cardiomyopathy.BackgroundSerum levels of ST2 are elevated in heart failure. The relationship of ST2 to hemodynamic variables, source of ST2, and expression of ST2L and IL-33 in the cardiovascular system are unknown.MethodsSerum ST2 (pg/ml; median [25th, 75th percentile]) was measured in patients with LV hypertrophy (aortic stenosis) (n = 45), congestive cardiomyopathy (n = 53), and controls (n = 23). ST2 was correlated to N-terminal pro-brain natriuretic peptide, C-reactive protein, and hemodynamic variables. Coronary sinus and arterial blood sampling determined myocardial gradient (production) of ST2. The levels of ST2, ST2L, and IL-33 were measured (reverse transcriptase-polymerase chain reaction) in myocardial biopsies and leukocytes. The ST2 protein production was evaluated in human endothelial cells. The IL-33 protein expression was determined (immunohistochemistry) in coronary artery endothelium.ResultsThe ST2 protein was elevated in aortic stenosis (103 [65, 165] pg/ml, p < 0.05) and congestive cardiomyopathy (194 [69, 551] pg/ml, p < 0.01) versus controls (49 [4, 89] pg/ml) and correlated with B-type natriuretic peptide (r = 0.5, p < 0.05), C-reactive protein (r = 0.6, p < 0.01), and LV end-diastolic pressure (r = 0.38, p < 0.03). The LV ST2 messenger ribonucleic acid was similar in aortic stenosis and congestive cardiomyopathy versus control (p = NS). No myocardial ST2 protein gradient was observed. Endothelial cells secreted ST2. The IL-33 protein was expressed in coronary artery endothelium. Leukocyte ST2L and IL-33 levels were highly correlated (r = 0.97, p < 0.001).ConclusionsIn human hypertrophy and failure, serum ST2 correlates with the diastolic load. Though the heart, endothelium, and leukocytes express components of ST2/ST2L/IL-33 pathway, the source of circulating serum ST2 is extra-myocardial.

Treatment strategies and outcome of ST-elevation myocardial infarction (STEMI) have been mainly studied in middle-aged patients. With increasing lifetime expectancy, the proportion of octogenarians will substantially increase. We aimed to evaluate whether the benefit of currently recommended reperfusion strategies is maintained in octogenarians. Reperfusion therapy and in-hospital mortality were evaluated in 1,092 octogenarians and compared with 7,984 STEMI patients < 80 years old based on data from the prospective Belgian STEMI registry. The octogenarian STEMI group had more cardiovascular comorbidities, contained more female patients and presented more frequently with cardiac failure (Killip class > 1, 40 vs. 20 %) compared with their younger counterparts (all p < 0.05). Although the rate of thrombolysis was similar (9.2 vs. 9.9 %) between both groups, a conservative approach was chosen more frequently (13.8 vs. 4.7 %), while PCI was performed less frequently (76.9 vs. 85.4 %) in octogenarians (p < 0.001). Moreover, ischemic time and door-to-needle/balloon time were longer for octogenarians. In-hospital mortality for octogenarians was 17.8 vs. 5.5 % in the younger group [adjusted OR 2.43(1.92-3.08)]. In haemodynamically stable octogenarians, PCI seemed to improve outcome compared with thrombolysis or conservative treatment (5.7 vs. 12.7 vs. 8.5 %, p = 0.09). In octogenarians with cardiac failure, in-hospital mortality was extremely high independent of the chosen reperfusion therapy (34.6 vs. 31.6 vs. 36.3 %, p = 0.88). In-hospital mortality in octogenarian STEMI patients was high and related to a high prevalence of cardiac failure. Less PCI was performed in the octogenarian group compared with the younger patients, although mortality benefit of PCI was maintained in haemodynamically stable octogenarians.

Aims: Reports examining local ST elevation myocardial infarction (STEMI) networks focused mainly on percutaneous coronary intervention (PCI)-related time issues and outcomes. To validate the concept of STEMI networks in a real-world context, more data are needed on management and outcome of an unselected community based STEMI population. Methods and results: The current study evaluated reperfusion strategies and in-hospital mortality in 8500 unselected STEMI patients admitted to 47 community hospitals (n=3053) and 25 PCI-capable hospitals (n=5447) in the context of a nationwide STEMI network programme that started in 2007 in Belgium. The distance between the hub and spoke hospitals ranged from 2.2 to 47 km (median 15 km). A propensity score was used to adjust for differences in baseline characteristics. Reperfusion strategy was significantly different with a predominant use of primary PCI (pPCI) in PCI-capable hospitals (93%), compared to a mixed use of pPCI (71%) and thrombolysis (20%) in community hospitals. A door-to-balloon time 70% use of pPCI, in-hospital mortality was comparable between community hospitals and PCI-capable hospitals. Participation in the STEMI network programme was associated with an increased adherence to reperfusion guidelines over time.

Background Current ST-segment elevation myocardial infarction guidelines regarding reperfusion strategy are based on trials conducted before the application of routine invasive evaluation after thrombolysis. Modern thrombolysis may affect the previously observed mortality difference between primary percutaneous coronary intervention (PPCI) and thrombolysis. Methods In-hospital mortality was prospectively assessed in 5295 patients with ST-segment elevation myocardial infarction admitted to 73 Belgian hospitals from July 1, 2007, through December 31, 2009. A total of 4574 patients (86.4%) were treated with PPCI and 721 (13.6%) received thrombolysis; of these thrombolysis patients, 603 (83.6%) underwent subsequent invasive evaluation. The Thrombolysis in Myocardial Infarction risk score was used to stratify the study population by low (n = 1934), intermediate (n = 2382), and high (n = 979) risk. Results In-hospital mortality in the PPCI patients was 5.9% vs 6.6% in the thrombolysis patients. After adjustment for differences in baseline risk profile, a significant mortality benefit was only present in the high-risk groups: 23.7% in the PPCI patients vs 30.6% in the thrombolysis patients. For patients not at high risk, the mortality difference was marginal. For low-risk patients, mortality was 0.3% in the PPCI patients vs 0.4% in the thrombolysis patients. For intermediate-risk patients, mortality was 2.9% in the PPCI patients vs 3.1% in the thrombolysis patients. Subgroup analysis revealed that the mortality benefit of PPCI compared with early thrombolysis (door-to-needle time

We present a patient with acute retrosternal pain and dyspnoea. Clinical examination revealed a woman in shock with a loud holosystolic murmur and congested jugular veins. Echocardiography showed severe mitral insufficiency. At transoesophageal echocardiography a large mass was seen in the right atrium,The differential diagnosis was a thrombus or an intracardiac tumour. Subsequent histology revealed a non-Hodgkin lymphoma in the right atrium, the wall of the left atrium extending to the mitral valve and further location in the pelvis and duodenum,The discussion incorporates a brief overview of the literature.

In the Belgian STEMI-registry, women -are older and have more comorbidities -are more severely ill at presentation -have higher crude in-hospital mortality rates After adjustment for appropriate covariates sex-related differences in choice of reperfusion therapy and in-hospital mortality do not remain significant. Primary PCI is not associated with higher mortality in women and should be advocated in this high risk population The authors report that there are no disclosures relevant to this poster presentation protected eCRF via www.biwacstemi.be Introduction

Objectives: To determine the value of the TIMI risk score in the individual risk stratification of patients with unstable angina/non‐ST segment elevation myocardial infarction (UA/NSTEMI). Background: TIMI risk score is a validated tool to identify groups of patients at high risk for major cardiac events. Its prognostic value in individual patients with current diagnostic tools and therapy is unknown. Methods: TIMI risk score was assessed in patients with UA/NSTEMI admitted to six Belgian hospitals and related to clinical outcome at 30 days. Results: Of the 500 patients enrolled, 49.4% were placed in the low TIMI risk group (score = 03) and 50.6% in the high‐risk group (score = 47). Multivariate analysis identified raised cardiac markers and invasive strategy, but not high TIMI risk score as independent predictors of death and new myocardial infarction (MI). Moreover, the incidence of death and MI in the low TIMI risk group with positive cardiac markers was not lower than in the high TIMI risk group with positive markers: 15.1% versus 17.8% (P = 0.7). Conclusions: TIMI risk score is of limited value for individual risk stratification. The presence of positive cardiac markers (troponin) appears to be a more powerful prognostic marker.

Clinical signs of cardiac involvement can be the first presentation of systemic sarcoidosis. In young or middle-aged patients presenting with conduction abnormalities cardiac sarcoidosis should always be included in the differential diagnosis. If the diagnosis is made before severe systolic dysfunction has occurred, treatment with steroids can render excellent results.

Right-to-left shunting through a foramen ovale complicating acute right ventricular infarction and resulting in severe arterial hypoxemia has been described eight times before. Treatment strategies have often aimed at reducing the shunt. Four patients died. Less attention has been paid to attempts at revascularization and, despite a high incidence of atrioventricular conduction disturbances, to temporary dual-chamber pacing. We describe herein two patients with postcardiac surgical right ventricular infarction complicated by severe right-to-left interatrial shunting. Treatment strategy was aimed at improving right ventricular function, and right-to-left shunting ceased. All efforts should be directed at treating right ventricular dysfunction, which is the cause of the clinical picture, and not at reducing the shunt, which is a secondary phenomenon.

Background —Despite early recanalization of an occluded infarct artery, reperfusion at the level of the microcirculation may remain impaired owing to a process of microvascular reperfusion injury. Methods and Results —Microvascular reperfusion injury was studied in 91 patients with acute myocardial infarction (AMI) by evaluation of the resolution of ST-segment elevation after successful PTCA. Impaired microvascular reperfusion, defined as the presence of persistent (≥50% of initial value) ST-segment elevation (ST ≥50%) at the end of coronary intervention, was observed in 33 patients (36%) and was independently correlated with low systolic pressure on admission and high age. Patients ≥55 years of age with systolic pressures ≤120 mm Hg were at high risk for development of impaired reperfusion compared with patients not meeting these criteria (72% versus 14%, P P =0.01); nonfatal MI rate, 9% versus 2% ( P =0.1); and total major adverse cardiac event (MACE) rate, 45% versus 15% ( P Conclusions —Impaired microvascular reperfusion, as evidenced by ST ≥50% after successful recanalization, occurs in more than one third of our AMI patients, especially in older patients with low systolic pressure. Its detrimental implications on clinical outcome reinforce the need to develop adjunctive agents that attenuate the process of reperfusion injury.

Background: Mortality in female patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary angioplasty (pPCI) is higher than in men. We examined gender differences in the prevalence and prognostic performance of renal dysfunction at admission in this setting. Methods. A multicenter retrospective sub-analysis of the Belgian STEMI-registry identified 1,638 patients (20.6% women, 79.4% men) treated with pPCI in 8 tertiary care hospitals (January 2007-February 2011). The estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI equation. Main outcome measure was in-hospital mortality. Results: More women than men suffered from renal dysfunction at admission (42.3% vs. 25.3%, p < 0.001). Mortality in women was doubled as compared to men (9.5 vs. 4.7%, OR (95% CI) = 2.12 (1.36-3.32), p, SCOPUS: ar.j, info:eu-repo/semantics/published

Severe heart failure in acute rheumatic myocarditis is rare. It may be rapidly reversible with treatment, so maximal medical treatment and, if necessary, mechanical support should be given before heart transplantation is considered.

OBJECTIVES: We tested the hypothesis that the tissue Doppler imaging (TDI)-derived positive preejection velocity (+VIC) can predict the recovery of contractile function after revascularization in patients with a recent myocardial infarction. BACKGROUND: In experimental studies, the presence and extent of TDI-derived +VIC correlated with the extent of viable myocardium. METHODS: Forty-three patients with a large myocardial infarction and an occluded left anterior descending (n = 38) or dominant right coronary (n = 5) artery were selected. The median duration of occlusion was 24 h. Longitudinal myocardial velocities were recorded at rest by pulsed-wave TDI echocardiography 6 ± 2 h after revascularization. Functional recovery was defined as an increase in segmental chordal shortening ≥10% at three-month follow-up left ventricular angiogram as compared with baseline. RESULTS A good quality TDI signal was obtained in 309 of 324 analyzed segments (95.4%). Severe dysfunction was present in 198 segments of which 126 (64%) showed recovery at three-month follow-up. Sampling of all dysfunctional segments lasted 11 ± 4 min per patient. Sensitivity, specificity, and accuracy of the +VIC to predict segmental recovery were 91%, 71%, and 84%, respectively. The percentage of segments that were dysfunctional at angiography but showed a +VIC correlated with improvement of both global left ventricular ejection fraction (r = 0.60, p = 0.001) and wall motion score index (r = -0.78, p < 0.0001) at follow-up. CONCLUSIONS: Assessment of +VIC by pulsed-wave TDI is a simple and accurate method that predicts recovery of contractile function after revascularization in patients with a recent myocardial infarction. © 2004 by the American College of Cardiology Foundation.
