RESUMO
BACKGROUND: Distal embolization during primary percutaneous coronary intervention (p-PCI) in the treatment of ST-segment elevation myocardial infarction (STEMI) is associated with a poor prognosis. In this situation, thrombectomy is performed to prevent distal embolization and to restore myocardial reperfusion. The aim of our study was to determine angiographic predictors of angiographically visible distal embolization (AVDE) in patients with STEMI treated by pPCI with thrombectomy. PATIENTS AND METHODS: This prospective study included all consecutive patients who underwent pPCI with thrombectomy for STEMI at our institution between October 2011 and December 2014 AVDE was defined as a distal filling defect with an abrupt cut-off in one of the peripheral coronary branches of the infarct-related artery, distal to the angioplasty site. Thrombectomy was considered positive when it removed thrombi, and successful when it improved coronary flow. RESULTS: Among the 346 patients included, 59 (17%) developed AVDE during pPCI. In multivariate analysis, the infarct-related right coronary artery (OR: 2.48, 95% CI: 1.36-4.52; pâ¯= 0.003) and a culprit lesion diameter of >3â¯mm (OR : 1.90, 95% CI: 1.01-3.56; pâ¯= 0.048) were identified as independent factors associated with AVDE during pPCI with thrombectomy for STEMI. The success of thrombectomy and the Syntax score were not associated with AVDE. CONCLUSION: AVDE complicating pPCI with thrombectomy in STEMI is frequent (17%) and a successful thrombectomy does not rule out AVDE.

In 2030, the European Union will include 14 to 17 million atrial fibrillation (AF) patients, with 120,000 to 215,000 new cases each year. The increase in the prevalence of this arrhythmia has led to the development of new therapeutic intervention strategies to manage the different aspects of this disease. Thus, endocavitary or epicardial ablation of AF, by radiofrequency or cryoablation, provides superior results to antiarrhythmic therapy in controlling symptoms and preventing heart failure in paroxysmal or persistent AF. In heart failure patients with advanced AF, the ablation of the atrioventricular junction associated with the implantation of a bi-ventricular pacemaker has just demonstrated its clear superiority, bringing this technique up to date. Finally, in the event of a major bleeding risk and contraindication to anticoagulants, percutaneous occlusion of the left atrium has proven its value in preventing AF-related embolic events. The future will certainly see the emergence of new technologies but also personalized strategies based on an optimal selection of the right candidates for these interventions, thanks in particular to the contribution of imaging before the procedure.

To interpret the electrocardiogram (ECG) of athletes, the recommendations of the ESC and the Seattle criteria define type 1 peculiarities, those induced by training, and type 2, those not induced by training, to rule out cardiomyopathy. The specificity of the screening was improved by Sheikh who defined "Refined Criteria," which includes a group of intermediate peculiarities. The aim of our study was to investigate the influence of static and dynamic components on the prevalence of different types of abnormalities. The ECGs of 1030 athletes performed during preparticipation screening were interpreted using these three classifications. Our work revealed 62/16%, 69/13%, and 71/7% of type 1 peculiarities and type 2 abnormalities for the ESC, Seattle, and Refined Criteria algorithms, respectively(P<.001). For type 2 abnormalities, three independent factors were found for the ESC and Seattle criteria: age, Afro-Caribbean origin, and the dynamic component with, for the latter, an OR[95% CI] of 2.35[1.28-4.33] (P=.006) and 1.90[1.03-3.51] (P=.041), respectively. In contrast, only the Afro-Caribbean origin was associated with type 2 abnormalities using the Refined Criteria: OR[95% CI] 2.67[1.60-4.46] (P<.0001). The Refined Criteria classified more athletes in the type 1 category and fewer in the type 2 category compared with the ESC and Seattle algorithms. Contrary to previous studies, a high dynamic component was not associated with type 2 abnormalities when the Refined Criteria were used; only the Afro-Caribbean origin remained associated. Further research is necessary to better understand adaptations with regard to duration and thus improve the modern criteria for ECG screening in athletes.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare form of systemic vasculitis in which cardiac involvement is frequent and severe, and accounts for half of EGPA-related deaths. ANCA-positive EGPA differs from ANCA-negative EGPA in that the former is significantly associated with renal involvement, peripheral neuropathy and biopsy proven vasculitis, whereas the latter is associated with cardiac involvement. Herein, we report a case of EGPA with myocarditis in a woman, who was successfully treated with steroids and cyclophosphamide. This report highlights the importance of diagnosing cardiac involvement in EGPA early, especially in ANCA-negative patients.

OBJECTIVE: To identify the predictive factors of myocardial stunning as assessed by the drop in post-stress Left Ventricular Ejection Fraction (LVEF) in patients with a recent history of myocardial infarction (MI). METHODS: We prospectively included 215 consecutive patients admitted for acute MI who underwent percutaneous coronary intervention with a greater than or equal to grade-3 TIMI flow in the culprit vessel. Six months after discharge, a post-stress/rest 99mTc-sestamibi gated SPECT was performed. The perfusion score was evaluated visually using a 17-segment model. The LVEF drop was considered significant if the post-stress LVEF was ≥ 5% below the rest LVEF (QGS® software). RESULTS: A post-stress LVEF drop was observed in 51 (24%) patients. Patients with an LVEF drop were more likely than patients with a stable post-stress LVEF to have diabetes (22% vs. 10%, p = 0.048), significant ischemia (SDS > 2) (51% vs. 28% p = 0.003) and higher rest LVEF [62% (56-69) vs. 56% (49-63) p < 0.001]. In contrast, summed rest score, related to infarct size, did not differ between the groups. Multivariate logistic regression analysis identified SDS > 2 (OR 3.78, 95% CI 1.8-7.92, p < 0.001), diabetes (OR 3.35, 95% CI 1.33-8.49; p = 0.011) and rest LVEF (OR 1.08, 95% CI 1.04-1.12, p < 0.001) as independent explanatory variables of an LVEF drop. CONCLUSION: In patients with recent MI and post-procedural grade-3 TIMI flow, ischemia and diabetes were independent predictive factors of myocardial stunning. The higher incidence of reversible perfusion abnormalities validates the model of myocardial stunning in the post-MI period, and excludes the potential involvement of myocardial necrosis.

INTRODUCTION: Iatrogenic complications are defined as adverse drug reactions or complications induced by non-drug interventions, such as cardiac devices or stimulation techniques. Iatrogenic complications occurring during hospital stay are known to be associated with increased hospital length of stay and mortality. Only few data are available on iatrogenic as cause of hospital admission, particularly in coronary care unit. In patient admitted in coronary care unit for iatrogenic, we aimed: (a) to analyse their prevalence, type and characteristics, (b) to analyse their in-hospital length of stay and mortality and (c) to evaluate the predictive factors of severity and mortality. METHODS: From 1st April 2008 to 31 January 2012, all the consecutive admissions caused by iatrogenic complications at the coronary care unit were prospectively included and classified in two groups: (1) pharmacological iatrogenic (beta-blockers, digoxin, calcium channel blockers, cordarone, several antiarrhythmic , anticoagulants, antiplatelets and others), (2) non-pharmacological iatrogenic (pacemaker, cardioverter-defibrillator, radiofrequency, coronary angiography and cardiac surgery including valve surgery). We excluded patients with intentional overdose. We also compared patients according to the severity (group 1: patients who just need a monitoring; and group 2: patients for whom there was invasive procedure or for whom we used vasoactive amine). RESULTS: Among 7244 patients admitted in coronary care unit during the inclusion period, 250 (3.4%) were admitted for iatrogenic complication, 136 in pharmacological group and 114 in non-pharmacological group. In non-pharmacological group, there was more men: 73.7% vs. 47.8% (P < 0.001), patients are younger: 67.3 ± 13.2 vs. 75.4 ± 15.8 (P < 0.001) and are more severe: 80.4% in group 2 vs. 69.4% (P = 0.05). The mortality in this group tends to be more important. According to the severity, there is no difference about drugs: 7.4 ± 3.4 vs. 6.8 ± 2.9 (P = 0.184) and are staying longer in hospital: 4.7 ± 3.2 days vs. 3.4 ± 2.4 (P = 0.009) for coronary care unit length of stay and 15 ± 13.7 vs. 10 ± 9.8 (P = 0.003) for total length of stay. CONCLUSION: Iatrogenic represent a non-negligible cause of admission in coronary care unit, which associated with significant mortality (8.8%) and with a trend toward a higher length of stay. Further studies are needed to determinate the origin of mortality and to better characterize patients at risk of iatrogenic.

OBJECTIVE: To examine the influence of obesity on the predictive value of the pro-B-type natriuretic peptide (NT-proBNP) assay in acute myocardial infarction. DESIGN: Prospective observational study. SETTING: All intensive care units in one region of France. Patients 2217 consecutive patients admitted for an acute myocardial infarction matched with respect to age, gender, Killip class and renal function. MAIN OUTCOME MEASURE: Cardiovascular death at one year. RESULTS: There were three groups (according to body mass index (BMI): obese, overweight and normal) of 739 matched patients. Median levels of NT-proBNP were considerably lower in high BMI patients, by about 20% in overweight and by 60% in obese patients, compared with normal BMI patients. An inverse relationship between the propeptide values and BMI was found in the overall study population (r = -0.20, p < 0.0001), and for both genders. In multivariate linear regression, BMI as a continuous variable was a predictor of the log NT-proBNP level, even when adjusted for potential confounders. CV mortality at 1-year follow-up was similar for the three BMI groups (p = 0.691). In multivariate logistic regression analysis, log NT-proBNP predicted mortality in normal (OR (95% CI) 3.48 (2.00 to 6.12)) and overweight (OR (95% CI) 3.96 (1.95 to 8.06)) patients, even when adjusted for confounders (GRACE risk score, left ventricular ejection fraction). However, in obese patients, propeptide levels failed to retain their independent prognostic value (OR (95% CI) 1.34 (0.86 to 2.08)). CONCLUSIONS: In this large population of patients with myocardial infarction, circulating NT-proBNP levels were considerably lower in obese patients; the significance of the propeptide level as an independent prognostic factor is severely compromised.

INTRODUCTION: Coronary thrombectomy is usually used to treat acute coronary syndrome. Many studies evaluated its benefit in this context however, it is still unknown if coronary characteristics are predictive of success or failure. The aim of our laboratory bench study was to evaluate the impact of angiographic characteristics on the thromboaspiration efficiency. METHODS: Glass tubes of 150 mm in the length were used, with five diameters: 2; 2.6; 3; 3.6 and 4 mm; and for each diameter, three angulations: no angulation; 90° and 120°. Blood sample were taken from healthy subject and thrombi of 3 and 6 hours old were performed, with a constant volume for each test. Thromboaspirations were performed with an Export(®) catheter (Medtronic). The primary endpoint was total thrombectomy. A total of 240 thromboaspirations were performed. RESULTS: A total thrombectomy was obtained for 71.2% of the tests. It was achieved more frequently with the smaller diameter, respectively: 100% for 2 mm, 81.3% for 2.6 mm, 89.6% for 3 mm vs 54.2% for 3.6 mm and 31.3% for 4 mm (P<0.001). No differences were observed between the 2 thrombi ages (73.3% for the 3 hours old thrombi and 69.2% for the 6 hours old thrombi, P = 0.476), nor between the three tube's angulations (77.5% for no angle, 66.3% for 90° and 70.0% for 120°, P = 0.278). RESULTS AND CONCLUSION: This study shows an impact of the coronary diameters on the rate of thromboaspiration success with an Export(®) catheter. Beyond 3 mm of diameter, the rate of success is divided by 2: for diameters less or equal to 3 mm, 90.3% of success vs 42.7% for diameters greater than 3 mm (P<0.001). There is no difference of efficiency between the 3 and 6 hours old thrombi, neither between the tube's angulations. However, this is a preliminary and further works are needed to clarify how to optimize the aspiration and the impact of other catheters.

BACKGROUND AND AIM: Reactive oxygen species (ROS) play an important role in the pathogenesis of many diseases including cardiovascular diseases. Several methods have been developed for the direct or indirect measurement of oxygen free radical and its by-products. The current study was designed to validate the new free oxygen radicals test (FORT) and to investigate the potential relationships between ROS and clinical or biological factors in male patients with acute myocardial infarction (AMI). METHODS: We analysed FORT values in samples from 66 patients with AMI. RESULTS: FORT values ranged from 324 to 1198 FORT units, with a median value of 581 (494-754) FORT units. In univariate analysis, FORT values were positively related only to LVEF <40% (p=0.005), levels of CRP (r=0.438, p<0.001) and peak CK (r=0.274, p=0.028). Multiple linear regression analysis showed that CRP (p=0.023), LVEF <40% (p<0.001) and the presence of diabetes (p=0.039) were independent predictors of serum FORT values. This statistical model can explain 45% of the variance in FORT values (R(2)=0.45). CONCLUSIONS: The FORT is a simple tool to assess circulating ROS in routine clinical practice. Oxidative conditions such as inflammation and diabetes are the major determinants of FORT values in patients with AMI.

Cardiovascular disease is the leading cause of early death and morbidity in developed countries and is becoming a growing problem in many developing countries. Currently, anti-coagulants play a major role in the management of the acute phase in association or not with reperfusion strategies. The combination of clopidogrel and aspirin, in accordance with the results of large randomized trials, is the treatment of reference. However two new drugs, a thienopyridine (prasugrel), and a cyclo-pentyl-triazolo-pyridine (ticagrelor) have shown their interest in major studies in comparison with clopidogrel. As a result, several effective P2Y12 receptor antagonist anti-platelet agents are now available in the therapeutic arsenal, and the cardiologist have to tailored the best drug scheme according the balance between the risk of hemorrhage and the benefits with regard to the ischemia to determine the optimal prescription for every patient.

BACKGROUND: Despite a common pathophysiological mechanism (ie, atherosclerosis) and similar vascular risk factors, few reliable studies have compared the epidemiology of stroke and acute myocardial infarction (AMI). METHODS: All first ever cases of stroke and AMI in Dijon, France (151 846 inhabitants) from 2001 to 2006 were prospectively recorded. The 30 day case fatality rates (CFRs) and vascular risk factors were assessed in both groups. RESULTS: Over the 6 years, 1660 events (1020 strokes and 640 AMI) were recorded. Crude incidence of stroke was higher than that of AMI (112 vs 70.2/100 000/year; p<0.001). With regard to sex, the relative incidence of stroke compared with AMI was 0.88 (95% CI 0.60 to 1.29; p = 0.51) in women <65 years and 2.32 (95% CI 1.95 to 2.75; p<0.001) in those >65 years whereas it was 0.60 (95% CI 0.42 to 0.86; p<0.001) in men below 55 years, 1.01 (0.81 to 1.24, p = 0.96) in those between 55 and 75 years and 2.01 (95% CI 1.48 to 2.71; p<0.001) at 75 years and older. CFRs at 30 days were similar for stroke and AMI (9.80% vs 9.84%; p = 0.5). Hyperglycaemia (>7.8 mmol/l) at onset was significantly associated with higher CFR in both stroke and AMI patients. The prevalence of male sex, hypercholesterolaemia and diabetes was higher in AMI patients whereas hypertension was more frequent in stroke patients. CONCLUSION: These findings will help health care authorities to evaluate future needs for stroke and AMI services, and to develop secondary prevention strategies.

OBJECTIVE: To examine the influence of age on the predictive value of N-terminal pro-brain natriuretic (NT-proBNP) peptide assay in acute myocardial infarction. DESIGN: Prospective observational study. SETTING: All intensive care units in one French region. PARTICIPANTS: 3291 consecutive patients admitted for an acute myocardial infarction, from the RICO survey (a French regional survey for acute myocardial infarction). MAIN OUTCOME MEASURE: Cardiovascular death at 1 year. RESULTS: Among the 3291 participants, mean age was 68 (SD 14) years and 2356 (72%) were men. In the study population, the median NT-proBNP concentration was 1053 (interquartile range 300-3472) pg/ml. Median values for age quarters 1 to 4 were 367 (119-1050), 696 (201-1950), 1536 (534-4146), and 3774 (1168-9724) pg/ml (P<0.001). A multiple linear regression analysis was done to determine the factors associated with the pro-peptide concentrations in the overall population. NT-proBNP was mainly associated with age, left ventricular ejection fraction, creatinine clearance, female sex, hypertension, diabetes, and anterior wall infarction. At one year's follow-up, 384 (12%) patients had died from all causes and 372 (11%) from cardiovascular causes. In multivariate analysis, NT-proBNP remained strongly associated with the outcome, beyond traditional risk factors including creatinine clearance and left ventricular ejection fraction, in each age group except in the youngest one (<54 years) (P=0.29). The addition of NT-proBNP significantly improved the performance of the statistical model in the overall study population (-2log likelihood 3179.58 v 3099.74, P<0.001) and in each age quarter including the upper one (1523.52 v 1495.01, P<0.001).The independent discriminative value of NT-proBNP compared with the GRACE score was tested by a diagonal stratification using the median value of the GRACE score and NT-proBNP in older patients (upper quarter). Such stratification strikingly identified a high risk group-patients from the higher NT-proBNP group and with a high risk score-characterised by a risk of death of almost 50% at one year. CONCLUSIONS: In this large contemporary non-selected cohort of patients with myocardial infarction, NT-proBNP concentration had incremental prognostic value even in the oldest patients, above and beyond the GRACE risk score and traditional biomarkers after acute myocardial infarction. These data further support the potential interest of clinical trials specifically assessing NT-proBNP measurement as a guide to current treatment strategies, as well as novel strategies, in older patients with acute myocardial infarction.

Neurotrophic-factors research is dominated by neurotrophins (NT): a family of polypeptides which includes molecules such as Nerve Growth Factor (NGF) and the Brain-Derived Neurotrophic Factor (BDNF). They are homodimeric polypeptides. NTs interact with classes of receptors on responsive cells: protein-tyrosine kinase-type receptors (Trk family). It is well established that the levels of NT determine the balance between cell survival and apoptosis during neural development. Recently, it has been shown that BDNF played a role in the etiology of some cardiovascular diseases: induction of angiogenesis in ischemic issues. Plasma BDNF was increased in the circulation in patients with unstable angina. BDNF was expressed in atheromatous intima and adventitia in human coronary artery. Our own studies suggest that BDNF serum levels in patients with acute myocardial infarction or under cardiopulmonary bypass could related to platelet activation, oxidative stress and inflammatory response. Thus, investigations of this new factor: BDNF will help to better understand vascular development and may lead to new therapeutic strategies for some cardiovascular diseases.

BACKGROUND: Towards the end of the 20th century, the city of Dijon, France, had a lower incidence of stroke than that found in other studies. It was hypothesized that genetic and environmental factors were responsible for this so-called French paradox. We aim to evaluate recent changes in stroke incidence to determine whether or not the Dijon exception still exists. METHODS: The population-based stroke registry of Dijon ascertained all first-ever strokes from 2000 to 2006. We calculated incidence to compare recent results with those obtained from a previous study period (1985-1999) and those of other population-based studies covering both the end of the 20th and the beginning of the 21st century. RESULTS: From 2000 to 2006, 1205 strokes were recorded. Crude and age-standardized incidence (to European and World population) rates were respectively 113, 107 and 72/100,000/year. No change was observed between 1985-1999 and 2000-2006, whereas other studies reported declining incidence. CONCLUSION: The incidence of stroke in Dijon remained lower than that found in similar studies, but the difference compared with results observed for the 20th century is shrinking. Therefore, the Dijon exception is decreasing, suggesting that it was rather an advance in prevention strategies that has diminished.

Cardiovascular disease is one of the major causes of early morbidity and death in the developed world, and is becoming a serious public health concern in many developing countries. Over the last 30 years, in the USA and France, coronary angioplasty has become a standard treatment for stable angina, and this despite the recommendations of Learned Societies concerning the treatment of this condition. Today, 85 % of angioplasty procedures are performed on patients with stable angina. This study presents meta-analyses that compare medical treatment with angioplasty, and examine the impact of these strategies on more specific populations such as the elderly and post-myocardial infarction patients. To our minds, this synthesis seems to be of particular importance as the COURAGE study has rekindled the debate by showing that improvements in medical treatment and way of life reduced mortality and the recurrence of MI at five years, whereas there was no positive impact of an invasive strategy in any of the subgroups. Nevertheless, as a whole, studies on this subject underscore the value of angioplasty in the medium term for symptom relief in the case of ineffective medical treatment, notably during an acute coronary syndrome both in patients under medical treatment and in those who underwent invasive therapy at the initial phase.

Epidemiological data concerning acute coronary syndromes in Europe are based on national registries, studies by the European Society of Cardiology within the framework of the EuroHeart Survey and on the study of European population sub-groups in large international cohorts. In this article, recently published studies will be reviewed, and the principal developments in different countries as well as the characteristics and particularities of the most recent epidemiological data will be highlighted. In Europe, the presentation of acute coronary syndromes (ACS) has evolved considerably over the last ten years. This evolution is characterized by a reduction in the proportion of acute coronary syndromes with ST-segment elevation (STEMI) and by ageing populations.

Cardiovascular disease is the primary cause of early death and morbidity in the industrialized world and is becoming a growing problem in many developing countries. Coagulation inhibitors play a major role in the management of the acute phase of ACS whether in association with reperfusion strategies or not. Currently, and in accordance with the results of major randomised studies, for medium and long-term management, the association of Clopidogrel and aspirin is the treatment of choice. However, despite the recognised benefits of this therapeutic strategy and above all the recommendations of learned societies, which have placed this bi-therapy in class I, according to national and international registries it is still underused. Moreover, all of these registries have confirmed, in the real world, the negative impact of not prescribing this antiplatelet therapy on morbidity and mortality after both ST and non-ST elevation acute coronary syndrome. which shows the difficulty of applying to everyday clinical practice the results of major randomised cohorts.

BACKGROUND: B-type natriuretic peptide and the N-terminal fragment of its prohormone, N-terminal pro-brain natriuretic peptide (Nt-proBNP), provide valuable prognostic information on short- and long-term mortality in patients with acute coronary syndrome AIM: To investigate the association between plasma NT-proBNP levels and ST-segment resolution (STR) after reperfusion in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: Consecutive patients from the French regional RICO survey with STEMI who were treated by primary PCI or lysis <12 h were included. Blood sample was taken on admission to measure plasma NT-proBNP. Maximal ST segment elevation was measured on the single worst ECG lead before and 90 min after reperfusion. Patients were categorized as STR(-) (<50% STR) or STR(+) (>or=50% STR). RESULTS: Of the 486 patients included, 133 (27%) were STR(-). STR(-) patients had similar cardiovascular risk factors but higher in-hospital mortality (5% vs. 1%, p=0.03) than STR(+) patients. The STR(-) group had higher median (IQR) levels of Nt-proBNP: 938 (211-3272) vs. 533 (169-1471) pg/ml, p=0.003. On multivariate analysis, the highest quartile of Nt-ProBNP, Q waves and lysis were independent risk factors for incomplete STR. DISCUSSION: Our data show a strong association between high levels of Nt-proBNP at admission and incomplete STR, suggesting that Nt-proBNP may be useful for early risk stratification in reperfusion therapy after acute myocardial infarction.

Peroperative infarction (POI) is a frequent and serious event, which is associated with an increase in morbidity and mortality; the risk is aggravated to varying degrees by the techniques of anaesthesia and surgery used. The preoperative evaluation of risk, which combines clinical and paraclinical criteria is described in the algorithm of the new AHA/ACC guidelines. In order to avert these ischemic episodes, beta-blockers must be continued or introduced during vascular surgery. In other types of surgery, they must be considered. It is difficult to diagnose MI in a per-operative context. The electrocardiogram print out and troponin kinetics will identify patients in the postoperative phase that should be oriented towards cardiovascular evaluation and therapy.
