Syndrome coronaire aigu : y a-t-il une place pour les anticoagulants oraux directs ?

International audienceVenous thromboembolism and atrial fibrillation are two important indications of direct oral anticoagulants. Acute coronary syndrome is another potential indication of prolonged antithrombotic therapy in addition to antiplatelet therapy. Phase 2 and 3 studies were conducted with different molecules at different doses in acute coronary syndrome in addition to dual antiplatelet therapy. Studies have not shown a reduction of ischemic events for dabigatran and apixaban, but an excess of bleeding complications was observed. A reduction of ischemic events and stent thrombosis was observed with low dose of rivaroxaban taken twice a day but with an increased risk of major bleeding complications. This data was used to obtain a European marketing authorization but the positioning of the molecule remains difficult. A new study is currently being conducted to test rivaroxaban in association with a P2Y12 inhibitor without aspirin. Direct oral anticoagulants can also be used after percutaneous coronary intervention in patients requiring long-term oral anticoagulants. Dedicated studies are currently being conducted to confirm the optimal doses and the ideal association of antithrombotic drugs

Should HIV-infected patients be screened for silent myocardial ischaemia using gated myocardial perfusion SPECT?

International audiencePurpose A higher prevalence of cardiovascular risk factors (CRFs) in HIV-infected patients, together with chronic infection and treatments, has resulted in an increased risk of silent myocardial ischaemia (SMI). The objective of this study was to evaluate whether myocardial SPECT should be used for screening HIV-infected patients with no clinical symptoms of coronary artery disease. Methods The prevalence of SMI detected by myocardial SPECT was determined in 94 HIV-infected patients with a normal clinical cardiovascular examination in relation to anthropomorphic parameters, CRFs, inflammatory and HIV infection status, and treatment. Results Coronary artery disease was detected in nine patients (eight with ischaemia, one with myocardial infarction), corresponding to 9.6 % positivity. All but two of the scintigraphic diagnoses of ischaemia were confirmed by coronarography. Univariate analysis revealed that the overall number of CRFs and the combination of gender and age were associated with a diagnosis of SMI (p<0.05). According to multivariate analysis, the only independent parameter significantly associated with the scintigraphic diagnosis of SMI was the combination of gender and age (p00.01). All the positive myocardial SPECT scans were in men older than 52 years with at least two other CRFs. In this subpopulation of 47 patients, the prevalence of SMI detected by myocardial SPECT reached 19.2 %. Conclusion In male HIV-infected patients older than 52 years and with at least two other CRFs, screening for SMI using myocardial SPECT was about four times more likely to be positive than in the general population. This may motivate physicians to advise these patients to undergo more systematic screening for SMI using this technique

Management of acute heart failure: Contribution of daily bedside echocardiographic assessment on therapy adjustment with impact measure on the 30-day readmission rate (JECICA)

There are currently one million heart failure (HF) patients in France and the rate is progressively increases due to population aging. Acute decompensation of HF is the leading cause of hospitalization in people over 65 years of age with a 25% re-hospitalization rate in the first month. Expenses related to the management of HF in France in 2013 amounted to more than one billion euros, of which 65% were for hospitalizations alone. The management of acute decompensation is a challenge, due to the complexity of clinical and laboratory evaluation leading to therapeutic errors, which in turn leads to longer hospitalization, high early re-hospitalization and complications. Therapeutic adjustment, especially diuretic, in the acute phase (during hospitalization) affects early re-hospitalization rates (within 30 days). These adjustments can be based on clinical estimation and laboratory parameters, but echocardiography has been shown to be superior in estimating filling pressures (FP) compared to clinical and laboratory parameters.We hypothesize that a simple daily bedside echocardiographic assessment could provide a reproducible estimation of FP with an evaluation of mitral inflow and the inferior vena cava (IVC). This could allow a more reliable estimate of the true blood volume of the patient and thus lead to a more suitable therapeutic adjustment. This in turn should lead to a decrease in early re-admission rate (primary endpoint) and potentially decrease six-month mortality and rate of complications.

Post resuscitation electrocardiogram for coronary angiography indication after out-of-hospital cardiac arrest

International audienceBackground: Coronary angiography is the standard of care after Out-of-Hospital Cardiac Arrest (OHCA), but its benefit for patients without persistent ST-segment elevation (STE) remains controversial.Methods: All patients admitted for coronary angiography after a resuscitated OHCA were consecutively included in this prospective study. Three patient groups were defined according to post-resuscitation ECG: STE or new left bundle branch block (LBBB) (group 1); other ST/T repolarization disorders (group 2) and no repolarisation disorders (group 3). The proportion and predictive factors of an acute coronary lesion, defined by acute coronary occlusion or thrombotic lesion or lesion associated with flow impairment, were evaluated according to different groups as well as thirty-day mortality.Results: Among 129 consecutive patients: 62 (48.1%), 30 (23.3%) and 30 (23.3%) patients were included in groups 1, 2 and 3 respectively. An acute coronary lesion was observed in 43% (n = 55) of patients, mainly in group 1 (n = 44, 70.9%). Initial coronary TIMI 0/1 flow was more frequently observed in group 1 than in group 2 (n = 25, 40.3% vs n = 1, 3.3%) and never in group 3. Chest pain and STE or new LBBB were independently associated with an acute coronary lesion (adj. OR = 7.14 [1.85–25.00]; p = 0.004 and adj. OR = 11.10 [3.70–33.33]; p < 0.001 respectively). In absence of any repolarization disorders, acute coronary lesion or occlusion were excluded with negative predictive values of 93.3% and 100% respectively. The one-month survival rate was 38.8% and was better in patients among the group 1 compared to those from the 2 other groups (n = 28, 45.2% vs n = 21, 35%, respectively; p = 0.014).Conclusion: Considering the high negative predictive value of post-resuscitation ECG to exclude acute coronary lesion and occlusion after OHCA, a delayed coronary angiography appears a reliable alternative for patients without repolarization disorders

One-year incidence and clinical impact of bleeding events in patients treated with prasugrel or clopidogrel after ST-segment elevation myocardial infarction

International audienceBACKGROUND:Little information is available on the long-term incidence of bleeding events after ST-segment elevation myocardial infarction (STEMI) with the current antithrombotic strategy.AIMS:To evaluate the effect of bleedings for up to 12months on clinical events and therapeutic compliance in unselected STEMI patients treated with prasugrel or clopidogrel.METHODS:Patients were treated with clopidogrel or prasugrel according to guidelines. The primary endpoint was first occurrence of a bleeding event from hospital discharge to 12months, assessed by the Bleeding Academic Research Consortium (BARC) classification using a dedicated questionnaire. Topography of bleedings, causes of premature cessation and ischaemic events were compared between clopidogrel- and prasugrel-treated patients.RESULTS:A total of 390 patients were enrolled (211 in the prasugrel group, 179 in the clopidogrel group). Elderly, female and low-body weight patients were more likely to receive clopidogrel. At 12months, the incidence of major bleedings (BARC 3) was lower with prasugrel (1% vs 6%; P=0.02), mainly due to fewer transfusions. Elderly age was a risk factor for severe bleeding. Premature treatment cessation was related to ischaemic complications (P=0.03), and occurred more frequently with prasugrel (P=0.001). One-year mortality was very low (1.9 per 100 person-years, 95% confidence interval 0.9-4.0), and was higher in the clopidogrel group (P=0.03).CONCLUSIONS:In this unselected STEMI population, the rate of major bleedings with prasugrel at 12months was low, but nuisance bleedings were frequent and led to more premature cessations than with clopidogrel. Prevention of bleeding complications, even minor, is necessary to prevent disruption of antithrombotic medication

Autoantibodies to citrullinated fibrinogen compared with anti-MCV and anti-CCP2 antibodies in diagnosing rheumatoid arthritis at an early stage: data from the French ESPOIR cohort.

International audienceOBJECTIVES: To compare the performance of anticitrullinated peptides/protein antibodies (ACPA) detected by three immunoassays in the French ESPOIR cohort of patients with early rheumatoid arthritis (RA) and undifferentiated arthritis (UA) and to study the relationship between ACPA and disease activity. METHODS: A diagnosis of RA (1987 American College of Rheumatology (ACR) criteria) was established at baseline in 497 patients and after a 2-year follow-up in 592 patients. At baseline, antibodies to citrullinated fibrinogen (AhFibA), antimutated citrullinated vimentin (anti-MCV) and anticyclic citrullinated peptide (anti-CCP2) were assayed and the individual and combined diagnostic sensitivities and predictive values of the tests were determined. Relationships between ACPA positivity and the 28-joint disease activity score and Health Assessment Questionnaire scores were analysed. RESULTS: At a diagnostic specificity of at least 98%, the three tests exhibited similar diagnostic sensitivities (47-48.5%). When considering as positive patients with at least one positive test, the sensitivity increased to 53.5% with a probable loss of specificity. Among the patients classified as having UA at baseline, 30% were positive for one ACPA, the positive predictive values for RA of the three tests ranging from 73% to 80% but increasing when two tests were associated. Whatever the test used, the addition of ACPA positivity to the 1987 criteria enhanced their sensitivity by 6%, close to that of the 2010 ACR/European League Against Rheumatism (EULAR) criteria. CONCLUSIONS: In early arthritis, AhFibA, anti-MCV and anti-CCP2 showed similar diagnostic sensitivity with a high diagnostic specificity and a similar high positive predictive value for RA. Adding ACPA to the 1987 ACR criteria significantly increased the number of patients classified as having RA, confirming the validity of the recent inclusion of the serological criterion in the ACR/EULAR criteria

Impact of Daily Bedside Echocardiographic Assessment on Readmissions in Acute Heart Failure: A Randomized Clinical Trial

International audienceAcute heart failure (AHF) management is challenging, with high morbidity and readmission rates. There is little evidence of the benefit of HF monitoring during hospitalization. The aim of the study was to assess whether daily bedside echocardiographic monitoring (JetEcho) improved outcomes in AHF. In this prospective, open, two parallel-arm study (clinicaltrials.gov: NCT02892227), participants from two university hospitals were randomized to either standard of care (SC) or daily treatment adjustment including diuretics guided by JetEcho evaluating left ventricular filling pressure and volemia. The primary outcome was 30-day readmission rate. Key secondary outcomes were six-month cumulative incidence death, worsening HF during hospitalization and increasing of myocardial and renal biomarkers. From 250 included patients, 115 were finally analyzed in JetEcho group and 112 in SC group. Twenty-two (19%) patients were readmitted within 30 days in JetEcho group and 17 (15%) in SC group (relative risk [RR] 1.26; 95% confidence interval [CI], 0.70–2.24; p = 0.4). Worsening HF occurred in 17 (14%) patients in the JetEcho group and 24 (20%) in the SC group (RR 0.7; 95% [CI] 0.39 to 1.2; p = 0.2). No significant difference was found between the two groups concerning natriuretic peptides and renal function (p > 0.05 for all). The cumulative incidence rate of death from any cause at six months from discharge was 8.7% in the JetEcho group and 11.6% in the SC group (HR 0.63, 95% [CI] 0.3–1.4, p = 0.3). In AHF patients, a systematic daily bedside echocardiographic monitoring did not reduce 30-day readmission rate for HF and short-term clinical outcomes

Safety of Percutaneous Coronary Intervention Without P2Y12 Inhibitor Pretreatment From a Cohort of Unselected Patients.

International audienceRecent studies have challenged systematic pretreatment with a P2Y12 inhibitor before percutaneous coronary intervention (PCI) in elective and non-ST segment elevation myocardial infarction (NSTEMI) patients. The aim of this study was to assess outcomes after performing PCI immediately after coronary angiography with an exclusive "on-the-table" P2Y12 inhibitor loading dose, by evaluating ischemic and bleeding complications in unselected patients

Early matched sibling hematopoietic cell transplantation for adult AML in first remission using an age-adapted strategy: long-term results of a prospective GOELAMS study.

International audienceThe LAM2001 phase 3 trial, involving 832 patients with acute myeloid leukemia (AML; median: 46 years) proposed HLA-identical sibling allograft HSCT for all patients with an identified donor. The trial compared reduced-intensity conditioning (RIC) for patients older than 50 years of age (N = 47) and myeloablative conditioning for younger patients (N = 117). BM HSCT was performed in the younger patients, while the older ones received a consolidation course, followed by peripheral blood allo-HSCT using RIC. The incidence of grade II-IV acute GVHD, was 51.9% (95% confidence interval [CI]: 42.1-61.8) and 11.3% (1.6-21.2) after myeloablative or RIC, respectively (P < .0001) and that of chronic GVHD 45.8% (95% CI: 34.8-56.7) and 41.7% (24.7-58.6; NS). Cumulative incidence of nonrelapse mortality at 108 months was 15.8% (95% CI: 9.8-23.2) for myeloablative, and 6.5% (0.2-16.2) for RIC (NS). CI of relapse at 108 months was 21.7% (95% CI: 13.9-28.6) and 28.6% (16.5-43.4; NS). Overall survival at 108 months was 63.4% (95% CI: 54.6-72.2) and 65.8% (52.2-72.2), respectively, after myeloablative or RIC (NS). RIC peripheral blood stem cell allo-HSCT is prospectively feasible for patients between the ages of 51 and 60 years without excess of relapse or nonrelapse mortality, and compares favorably with myeloablative marrow allo-HSCT proposed to younger patients
