New-onset atrial fibrillation in chronic coronary syndrome: the CLARIFY registry
Background and Aims:
Data on new-onset atrial fibrillation (NOAF) in patients with chronic coronary syndromes (CCS) are scarce. This study aims to describe the incidence, predictors and impact on cardiovascular outcomes of NOAF in CCS patients.
Methods:
Data from the international (45 countries) CLARIFY registry (prospeCtive observational LongitudinAl RegIstry oF patients with stable coronary arterY disease) were used. Among 29,001 CCS outpatients without previously reported AF at baseline, patients with at least one episode of AF/flutter diagnosed during 5-year follow-up were compared with patients in sinus rhythm throughout the study.
Results:
The incidence rate of NOAF was 1.12 [95% confidence interval (CI) 1.06-1.18] per 100 patient-years (cumulative incidence at 5 years: 5.0%). Independent predictors of NOAF were increasing age, increasing body mass index, low estimated glomerular filtration rate, Caucasian ethnicity, alcohol intake and low left ventricular ejection fraction, while high triglycerides were associated with lower incidence. NOAF was associated with a substantial increase in the risk of adverse outcomes, with adjusted hazard ratios of 2.01 (95% CI 1.61-2.52) for the composite of cardiovascular death, non-fatal myocardial infarction or non-fatal stroke, 2.61 (95% CI 2.04-3.34) for cardiovascular death, 1.64 (95% CI 1.07-2.50) for non-fatal myocardial infarction, 2.27 (95% CI 1.85-2.78) for all-cause death, 8.44 (95% CI 7.05-10.10) for hospitalization for heart failure and 4.46 (95% CI 2.85-6.99) for major bleeding.
Conclusions:
Among CCS patients, NOAF is common and is strongly associated with worse outcomes. Whether more intensive preventive measures and more systematic screening for AF would improve prognosis in this population deserves further investigation
Optimal or standard control of systolic and diastolic blood pressure across risk factor categories in patients with chronic coronary syndromes
Aims:
Guidelines have lowered blood pressure (BP) targets to <130/80 mmHg. We examined the benefit of intensive control for each BP component, versus the burden of other modifiable risk factors, in patients with chronic coronary syndromes (CCS).
Methods and results:
The CLARIFY registry (ISRCTN43070564) enrolled 32 703 CCS patients, from 2009−2010, with a 5-year follow-up. Patients with either BP component below European guideline safety boundaries (120/70 mmHg) were excluded, leaving 19 167 patients (mean age 63.8 ± 10.1 years, 78% men) in the present analysis. A multivariable-adjusted Cox proportional hazards model showed a gradual increase in cardiovascular risk (cardiovascular death, myocardial infarction, or stroke) when the number of uncontrolled risk factors (active smoking, no physical activity, low-density lipoprotein cholesterol ≥100 mg/dL, and diabetes with glycated haemoglobin ≥7%) increased [adjusted hazard ratio (HR): 1.34; 95% confidence interval (CI): 1.17−1.52, 1.65 (1.40−1.94), and 2.47 (1.90−3.21) for 1, 2, and 3 or 4 uncontrolled risk factors, respectively, versus 0], without significant interaction with BP. Although uncontrolled systolic (≥140 mmHg) and diastolic (≥90 mmHg) BP were both associated with higher risk than standard BP, standard BP was associated with higher risk than optimal control for only the diastolic component (adjusted HR: 1.08; 95% CI: 0.94−1.25 for systolic BP 130−139 versus 120−129 mmHg and 1.43; 95% CI: 1.27−1.62 for diastolic BP 80−89 versus 70−79 mmHg).
Conclusions:
Our results suggest that optimal BP target in CCS may be ≤139/79 mmHg, and that optimizing the burden of other risk factors should be prioritized over further reduction of systolic BP
External applicability of the Effect of ticagrelor on Health Outcomes in diabEtes Mellitus patients Intervention Study (THEMIS) trial: An analysis of patients with diabetes and coronary artery disease in the REduction of Atherothrombosis for Continued Health (REACH) registry.
THEMIS is a double-blind, randomized trial of 19,220 patients with diabetes mellitus and stable coronary artery disease (CAD) comparing ticagrelor to placebo, in addition to aspirin. The present study aimed to describe the proportion of patients eligible and reasons for ineligibility for THEMIS within a population of patients with diabetes and CAD included in the Reduction of Atherothrombosis for Continued Health (REACH) registry.
The THEMIS eligibility criteria were applied to REACH patients. THEMIS included patients ≥50 years with type 2 diabetes and stable CAD as determined by either a history of previous percutaneous coronary intervention, coronary artery bypass grafting, or documentation of angiographic stenosis of ≥50% of at least one coronary artery. Patients with prior myocardial infarction or stroke were excluded. In REACH, 10,156 patients had stable CAD and diabetes. Of these, 6515 (64.1%) patients had at least one exclusion criteria. From the remaining population, 784 patients did not meet inclusion criteria (7.7%) mainly due to absence of aspirin treatment (7.2%), yielding a 'THEMIS-eligible population' of 2857 patients (28.1% of patients with diabetes and stable CAD). The main reasons for exclusion were a history of myocardial infarction (53.1%), use of oral anticoagulation (14.5%), or history of stroke (12.9%). Among the 4208 patients with diabetes and a previous PCI, 1196 patients (28.4%) were eligible for inclusion in the THEMIS-PCI substudy.
In a population of patients with diabetes and stable coronary artery disease, a sizeable proportion appear to be 'THEMIS eligible.'

The Changing Landscape for Stroke\ua0Prevention in AF: Findings From the GLORIA-AF Registry Phase 2
Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase 1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age 6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score 652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc = 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N = 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.

Unmet needs of young interventional cardiologists: the EAPCI Young survey
Aims: As part of the EAPCI Young Initiative, the European Association of Percutaneous Cardiovascular Interventions (EAPCI) conducted a survey to address the educational needs of young interventional cardiologists. Methods and results: A questionnaire was distributed to all individuals registered in the ESC database aged <36 years with an interest in interventional cardiology. Nearly two-thirds of participants (60%) indicated that they had difficulty in finding a fellowship training position. The desire for a fellow's course at European level was expressed by 95%, while 94% were in favour of developing a network of young interventional cardiologists in Europe. More than three-quarters of respondents (79%) said they had had difficulty in obtaining funding to attend EuroPCR. Multiple difficulties were identified in setting up a research programme, two of the more frequent being problematic access to research networks and the difficulties of finding a mentor. Career orientation was identified as another issue, with more than half of respondents (59%) declaring they followed career options by chance. Conclusions: The survey underlines the need to fill a gap in order to address the needs of young interventional cardiologists. It may serve as a starting point for developing educational initiatives targeted at young interventional cardiologists
Similar Cardioventilatory but Greater Neuromuscular Stimuli With Interval Drop Jump Than With Interval Running
International audienceDrop jumps and high-intensity interval running are relevant training methods to improve explosiveness and endurance performance, respectively. Combined training effects might, however, be achieved by performing interval drop jumping
Increased Fatigue Response to Augmented Deceptive Feedback during Cycling Time Trial.
International audienceThis study aimed to investigate the effect of different magnitudes of deception on performance and exercise-induced fatigue during cycling time-trial.Following three familiarization visits, three females and eight males performed three 5 km cycling time-trials while following a simulated dynamic avatar reproducing either 100% (5K100%), 102% (5K102%) or 105% (5K105%) of the subject's previous fastest trial. Quadriceps muscle activation was quantified with surface electromyography. Fatigue was quantified by pre- to post-exercise (10 s through 15 min recovery) changes in quadriceps maximal voluntary contraction (MVC) force, potentiated twitch force evoked by electrical femoral nerve stimulation (QTSingle) and voluntary activation (VA, twitch interpolation technique).Greater quadriceps muscle activation in 5K102% vs. 5K100% (12±11%) was found in parallel with a 5±2% and 2±1% improvement in power output and completion time, respectively (p < 0.01). Exercise-induced reduction in MVC force and VA were 14±19% and 28±31% greater at exercise termination (at 10 s) whereas QTSingle recovery (from 10 s to 15 min) was 5±5% less in 5K102% vs. 5K100% (p < 0.01). No difference in performance or fatigue indices measured at exercise termination was found between 5K100% and 5K105%.Muscle activation and performance improvements during a deceptive cycling time-trial were achieved only with a 2% magnitude of deception and were associated with a further impairment in MVC force, QTSingle recovery and VA compared to control. Performance improvement during cycling time-trial with augmented deceptive feedback therefore resulted in exacerbated exercise-induced peripheral and central fatigue
Blood transfusion, bleeding, anemia, and survival in patients with acute myocardial infarction: FAST-MI registry
International audienceBackground An association between transfusion during index hospitalization and increased subsequent mortality has been reported in acute myocardial infarction (AMI). Whether this reflects the prognostic role of transfusion per se, or the impact of the index event leading to transfusion, remains unclear. We sought to evaluate the impact of transfusion on mortality in patients with AMI. Methods Using the nationwide FAST-MI 2005 AMI registry, we recorded anemia on admission, Thrombolysis in Myocardial Infarction major or minor bleeding, and transfusions during hospital stay. Multivariable analyses were performed to identify independent predictors of in-hospital and 5-year mortality. Cohorts of patients matched for propensity to receive transfusion were compared. Results Among 3541 patients with AMI, 827 (23.4%) had anemia on admission, 114 (3.2%) had minor or major bleeding, and 151 (4.3%) underwent transfusion. After multivariable analysis, both anemia and bleeding were independently associated with 5-year mortality (hazard ratio [HR] 1.4, 95% CI 1.2-1.6 and HR 1.4, 95% CI 1.1-1.8, respectively), whereas transfusion did not appear to be an independent predictor (HR 1.1, 95% CI 0.8-1.5). Mortality at 5 years did not differ between cohorts matched for propensity to receive transfusion. Conclusions In this cohort, anemia on admission and bleeding during hospitalization were both associated with increased 5-year mortality in patients with myocardial infarction. Conversely, transfusion per se was not associated with lower survival. Further work is needed to clarify the optimal transfusion strategy in patients with bleeding or anemia and myocardial infarction
