Background
A combination of circulating biomarkers associated with excessive myocardial collagen type-I cross-linking or CCL+ (i.e., decreased carboxy-terminal telopeptide of collagen type-I to matrix metalloproteinase-1 ratio) and with excessive myocardial collagen type-I deposition or CD+ (i.e., increased carboxy-terminal propeptide of procollagen type-I) has been described in heart failure (HF) patients and associates with poor outcomes.Objectives
The purpose of this study was to investigate whether the CCL+CD+ combination of biomarkers associates with atrial fibrillation (AF).Methods
Biomarkers were analyzed in serum samples from 242 HF patients (study 1) and 150 patients referred for AF ablation (study 2). Patients were classified into 3 groups (CCL?CD?, CCL+CD? or CCL?CD+, and CCL+CD+) in accordance to biomarker threshold values. Left atrial electroanatomic high-density mapping was performed in 71 patients from study 2.Results
In study 1, 53.7% patients had AF at baseline and 19.6% developed AF (median follow-up 5.5 years). Adjusted odds and hazard ratios associated with baseline and new-onset AF, respectively, were both ≥3.3 (p ≤ 0.050) in CCL+CD+ patients compared with CCL?CD? patients, with nonsignificant changes in the other group. In study 2, 29.3% patients had AF recurrence during 1-year post-ablation. The adjusted hazard ratio for AF recurrence was 3.4 (p = 0.008) in CCL+CD+ patients compared with CCL?CD? patients, with nonsignificant changes in the other group. The CCL+CD+ combination added incremental predictive value over relevant covariables. CCL+CD+ patients exhibited lower left atrial voltage than the remaining patients (p = 0.005).Conclusions
A combination of circulating biomarkers reflecting excessive myocardial collagen type-I cross-linking and deposition is associated with higher AF prevalence, incidence, and recurrence after ablation. 相似文献2.

Background
Patients with mitral stenosis and atrial fibrillation (AF) require anticoagulation for stroke prevention. Thus far, all studies on direct oral anticoagulants (DOACs) have excluded patients with moderate to severe mitral stenosis.Objectives
The aim of this study was to validate the efficacy of DOACs in patients with mitral stenosis.Methods
The study population was enrolled from the Health Insurance Review and Assessment Service (HIRA) database in the Republic of Korea, and it included patients who were diagnosed with mitral stenosis and AF and either were prescribed DOACs for off-label use or received conventional treatment with warfarin. The primary efficacy endpoint was ischemic strokes or systemic embolisms, and the safety outcome was intracranial hemorrhage.Results
A total of 2,230 patients (mean age 69.7 ± 10.5 years; 682 [30.6%] males) were included in the present study. Thromboembolic events occurred at a rate of 2.22%/year in the DOAC group, and 4.19%/year in the warfarin group (adjusted hazard ratio for DOAC: 0.28; 95% confidence interval: 0.18 to 0.45). Intracranial hemorrhage occurred in 0.49% of the DOAC group and 0.93% of the warfarin group (adjusted hazard ratio for DOAC: 0.53; 95% confidence interval: 0.22 to 1.26).Conclusions
In patients with AF accompanied with mitral stenosis, DOAC use is promising and hypothesis generating in preventing thromboembolism. Our results need to be replicated in a randomized trial. 相似文献3.

Background
Chronic obstructive pulmonary disease (COPD), a known risk factor for the development of congestive heart failure (CHF), was recently shown to predict the prevalence of atrial fibrillation (AF). Here, we explore the influence of AF on cardiac prognosis in COPD patients.Methods
A total of 339 consecutive patients who underwent spirometry from 2010 to 2013 for various reasons were retrospectively examined. Based on the diagnostic criteria, patients were stratified into COPD and non-COPD groups, which were both further divided into those with AF (chronic AF or paroxysmal AF) or sinus rhythm (SR) based on previous electrocardiography results. Significances of differences in cardiac events were assessed by the chi-square test. Multivariate logistic regression analyses and Cox proportional hazard models were applied to evaluate the influence of AF on cardiac events.Results
Of the 339 patients, 190 were diagnosed with COPD, with 42 of these were having AF. During the mean follow-up period of 7.4 ± 0.8 years, CHF developed more frequently in COPD patients with AF than in COPD patients without AF [50% vs 7%; odds ratio (OR) 12.4, 95% confidence interval (CI): 5.25–29.49, p < 0.05]. AF was an independent predictor of CHF development (OR 20.4, 95% CI: 6.55–79.80, p < 0.05) and cardiac mortality (OR 2.8, 95% CI: 1.79–4.72, p < 0.05). Moreover, positive correlations were found between the severity of pulmonary obstruction with AF and CHF development (R = 0.69, p < 0.05), as well as cardiac mortality (R = 0.78.p < 0.05).Conclusions
These results suggest that AF may be strongly associated with cardiac mortality and CHF in COPD patients. 相似文献4.

Objectives
This study hypothesized that compensatory mitral leaflet area (MLA) adaptation occurs in patients with persistent atrial fibrillation (AF) without left ventricular (LV) dysfunction but has limitations that augment mitral regurgitation (MR). The study also explored whether asymmetrical annular dilation is matched by relative leaflet enlargement.Background
Functional MR occurs in patients with AF and isolated annular dilation, but the relationship of MLA adaptation with annular area (AA) is unknown.Methods
Three-dimensional echocardiographic images were acquired from 86 patients with quantified MR: 53 with nonvalvular persistent AF (23 MR+ with moderate or greater MR, 30 MR?) without LV dysfunction or dilation and 33 normal controls. Comprehensive 3-dimensional analysis included total diastolic MLA, adaptation ratios of MLA to annular area and MLA to leaflet closure area, and annular and tenting geometry.Results
Total MLA was 22% larger in patients with AF than in controls, thus paralleling the increased AA. However, as AA increased, adaptive indices (MLA/AA ratio and ratio of MLA to closure area) plateaued, becoming lowest in MR+ patients (ratio of MLA to closure area = 1.63 ± 0.17 controls, 1.60 ± 0.11 MR?, 1.32 ± 0.10 MR+; p < 0.001). MR increased as the ratio of MLA to closure area decreased (R2 = 0.68; p < 0.001). The posterior-to-anterior MLA ratio remained constant, whereas the posterior-to-anterior mitral annulus perimeter increased (1.21 ± 0.16 controls, 1.32 ± 0.20 MR?, 1.46 ± 0.19 MR+; p < 0.001). Multivariate MR determinants were annular area, total MLA to closure area, and posterior-to-anterior perimeter ratios.Conclusions
MLA adaptively increases in AF with isolated annular dilation and normal LV function. This compensatory enlargement becomes insufficient with greater annular dilation, and the leaflets fail to match asymmetrical annular remodeling, thereby increasing MR. These findings can potentially help optimize therapeutic options and motivate basic studies of adaptive growth processes. 相似文献5.

Background
Information on young patients with Brugada syndrome (BrS) and arrhythmic events (AEs) is limited.Objectives
The purpose of this study was to describe their characteristics and management as well as risk factors for AE recurrence.Methods
A total of 57 patients (age ≤20 years), all with BrS and AEs, were divided into pediatric (age ≤12 years; n = 26) and adolescents (age 13 to 20 years; n = 31).Results
Patients’ median age at time of first AE was 14 years, with a majority of males (74%), Caucasians (70%), and probands (79%) who presented as aborted cardiac arrest (84%). A significant proportion of patients (28%) exhibited fever-related AE. Family history of sudden cardiac death (SCD), prior syncope, spontaneous type 1 Brugada electrocardiogram (ECG), inducible ventricular fibrillation at electrophysiological study, and SCN5A mutations were present in 26%, 49%, 65%, 28%, and 58% of patients, respectively. The pediatric group differed from the adolescents, with a greater proportion of females, Caucasians, fever-related AEs, and spontaneous type-1 ECG. During follow-up, 68% of pediatric and 64% of adolescents had recurrent AE, with median time of 9.9 and 27.0 months, respectively. Approximately one-third of recurrent AEs occurred on quinidine therapy, and among the pediatric group, 60% of recurrent AEs were fever-related. Risk factors for recurrent AE included sinus node dysfunction, atrial arrhythmias, intraventricular conduction delay, or large S-wave on ECG lead I in the pediatric group and the presence of SCN5A mutation among adolescents.Conclusions
Young BrS patients with AE represent a very arrhythmogenic group. Current management after first arrhythmia episode is associated with high recurrence rate. Alternative therapies, besides defibrillator implantation, should be considered. 相似文献6.

Background
It is unclear whether the overall effectiveness and safety of direct oral anticoagulants (DOACs) are consistent in patients with nonvalvular atrial fibrillation (AF) and extremely low body weight (<50 kg).Objectives
This study compared DOACs with warfarin in AF patients with low body weight.Methods
Using data from the Korean National Health Insurance Service database from January 2014 to December 2016, AF patients with body weight ≤60 kg and who were treated with oral anticoagulants (n = 14,013 taking DOACs and n = 7,576 taking warfarin) were included and examined for ischemic stroke, intracranial hemorrhage (ICH), gastrointestinal bleeding, major bleeding, all-cause death, and composite outcome. The propensity score weighting was used to balance the 2 groups.Results
Baseline characteristics were well balanced between the 2 groups (mean age 73 years, mean CHA2DS2-VASc score 4, and 28% of patients weighed <50 kg). DOACs were associated with lower risks of ischemic stroke (hazard ratio [HR]: 0.591; 95% confidence interval [CI]: 0.510 to 0.686) and major bleeding (HR: 0.705; 95%: CI 0.601 to 0.825), which were caused by a reduction in ICH (HR: 0.554; 95% CI: 0.429 to 0.713) compared with warfarin. DOAC improved the net clinical benefit compared with warfarin (HR for composite outcome: 0.660; 95% CI: 0.606 to 0.717), and this was consistent in patients who weighed <50 kg (HR for composite outcome: 0.665; 95% CI: 0.581 to 0.762).Conclusions
In this real-world Asian AF population with low body weight, DOACs showed better effectiveness and safety than warfarin. These results were consistent in patients with extremely low body weight. Regular dosages of DOACs showed comparable results as reduced dosages of DOACs in both effectiveness and safety. 相似文献7.

Objectives
The aim of this study was to compare 1-year outcomes following transcatheter mitral valve (MV) repair in patients with and without atrial fibrillation (AF).Background
The development of AF in degenerative mitral regurgitation (MR) is considered a sign of MR progression and is associated with adverse clinical events. However, the impact of AF in patients undergoing transcatheter MV repair remains uncertain.Methods
The TVT (Transcatheter Valve Therapy) Registry was used to identify patients undergoing transcatheter MV repair with the MitraClip between November 2013 and June 2016. Using Centers for Medicare and Medicaid Services–linked data, the 1-year rate of death, heart failure hospitalization, stroke, and bleeding following transcatheter MV repair was compared in patients with and without AF. Outcomes were analyzed using multivariate Cox regression modeling.Results
A total of 5,613 patients underwent commercial transcatheter MV repair in the United States during the study period, including 3,555 (63%) with pre-existing AF. Compared with patients without AF, patients with AF were older, were more likely to be male and Caucasian, had more comorbidities, and had higher Society of Thoracic Surgeons Predicted Risk of Mortality scores (median 7% vs. 5%; p < 0.0001). Acute procedural success (post-procedural ≥2+ MR, 37.4% vs. 35.0%; p = 0.20) and in-hospital mortality were similar, but length of hospital stay was longer for patients with AF (mean 4.91 days vs. 4.37 days; p = 0.0004). A total of 3,261 patients were linked to Centers for Medicare and Medicaid Services claims data. After adjustment, patients with AF had a higher 1-year rate of death or HF (hazard ratio [HR]: 1.27; 95% confidence interval [CI]: 1.11 to 1.44; p < 0.001). Patients with AF had higher rates of mortality (HR: 1.44; 95% CI: 1.22 to 1.70; p < 0.001), HF hospitalization (HR: 1.17; 95% CI: 1.00 to 1.36; p = 0.05), stroke (HR: 1.63; 95% CI: 1.01 to 2.64; p = 0.047), and bleeding (HR: 1.34; 95% CI: 1.10 to 1.64; p = 0.004) at 1 year as well. Among those with AF, the risk for stroke was lower (HR: 0.55; 95% CI: 0.32 to 0.93; p = 0.026) among those on anticoagulation.Conclusions
In patients undergoing transcatheter MV repair, AF is common and is associated with worse clinical outcomes at 1 year despite similar acute procedural success. Further study is needed to investigate if early treatment of MR reduces the future risk for developing AF and to identify therapies that improve outcomes in these patients. 相似文献8.

Background
Epidemiology of patients with worsening heart failure and reduced ejection fraction (HFrEF) in the real-world setting is not well described.Objectives
The purpose of this study was to describe incidence, clinical characteristics, treatment, and outcomes of patients with HFrEF who develop worsening heart failure (HF) in the real-world setting.Methods
Data on patients with incident HFrEF from the National Cardiovascular Data Registry PINNACLE were linked to pharmacy, private practitioner, and hospital claims databases. Incidence, clinical characteristics, treatment (angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, beta-blocker, and mineralocorticoid receptor antagonist) and outcomes of patients with worsening HF, defined as ≥90 days of stable HF with subsequent worsening requiring intravenous diuretic agents, were assessed.Results
Of 11,064 HFrEF patients, 1,851 (17%) developed worsening HF on average 1.5 years following initial HF diagnosis. Patients who developed worsening HF were more likely to be African American, be octogenarians, and have higher comorbidity burden (p < 0.001). At the onset of worsening HF, 42.4% of patients were on monotherapy, 43.4% were on dual therapy, and 14.1% were on triple therapy. A total of 48%, 61%, and 98% of patients were on >50% target dose for angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, beta-blocker, and mineralocorticoid receptor antagonist, respectively. The 2-year mortality rate was 22.5%, and 56% of patients were rehospitalized within 30 days of the worsening HF event.Conclusions
In the real-world setting, 1 in 6 patients with HFrEF develop worsening HF within 18 months of HF diagnosis. These patients have a high risk for 2-year mortality and recurrent HF hospitalizations. The use of standard-of-care therapies both before and after the onset of worsening HF is low. With high unmet medical need, patients with worsening HF require novel treatment strategies as well as greater optimization of existing guideline-directed therapy. 相似文献9.

Background and aims
A Mediterranean-type diet enriched with extra virgin olive oil has been associated with a reduction in the incidence of atrial fibrillation (AF) in a population at high cardiovascular risk. However, no study has replicated these findings. In our study, we analyzed the association between olive oil consumption and AF in the SUN project, a cohort with young Spanish adults at low cardiovascular risk.Methods and results
We included all participants without prevalent AF at baseline (18,118 participants). Incident AF cases were confirmed by a cardiologist following a prespecified protocol. We used multivariable repeated-measurement Cox models adjusted for possible confounders (sex, age, BMI, and several classic cardiovascular risk factors).After a mean follow-up of 10.1 years, 94 AF incident cases were confirmed. Comparing to the lowest category of consumption (<7.9 g/d), the multivariable models showed hazard ratios (IC 95%) of 1.52 (0.93–2.48) for low-to-moderate, 1.44 (0.83–2.47) for moderate-to-high and 1.27 (0.56–2.86) for high olive oil intake. In a subgroup analysis stratified by overweight, an inverse although non-significant association was found only among overweight participants when we compared the highest vs the lowest category of consumption (p for interaction = 0.043).Conclusion
No association between olive oil and AF was found in this low-risk cohort, although the effect of extra-virgin olive oil on AF prevention especially among people with overweight deserves further investigation. 相似文献10.

Background
There are conflicting data regarding the relative effectiveness of renal sympathetic denervation (RSD) in patients with hypertension.Objectives
The purpose of this study was to evaluate the blood pressure (BP) response after RSD in sham-controlled randomized trials.Methods
Databases were searched through June 30, 2018. Randomized trials (RCTs) with ≥50 patients comparing catheter-based RSD with a sham control were included. The authors calculated summary treatment estimates as weighted mean differences (WMD) with 95% confidence intervals (CIs) using random-effects meta-analysis.Results
The analysis included 977 patients from 6 trials. The reduction in 24-h ambulatory systolic blood pressure (ASBP) was significantly greater for patients treated with RSD than sham procedure (WMD ?3.65 mm Hg, 95% CI: ?5.33 to ?1.98; p < 0.001). Compared with sham, RSD was also associated with a significant decrease in daytime ASBP (WMD ?4.07 mm Hg, 95% CI: ?6.46 to ?1.68; p < 0.001), office systolic BP (WMD ?5.53 mm Hg, 95% CI: ?8.18 to ?2.87; p < 0.001), 24-h ambulatory diastolic BP (WMD ?1.71 mm Hg, 95% CI: ?3.06 to ?0.35; p = 0.01), daytime ambulatory diastolic BP (WMD ?1.57 mm Hg, 95% CI: ?2.73 to ?0.42; p = 0.008), and office diastolic BP (WMD ?3.37 mm Hg, 95% CI: ?4.86 to ?1.88; p < 0.001). Compared with first-generation trials, a significantly greater reduction in daytime ASBP was observed with RSD in second-generation trials (6.12 mm Hg vs. 2.14 mm Hg; p interaction = 0.04); however, this interaction was not significant for 24-h ASBP (4.85 mm Hg vs. 2.23 mm Hg; p interaction = 0.13).Conclusions
RSD significantly reduced blood pressure compared with sham control. Results of this meta-analysis should inform the design of larger, pivotal trials to evaluate the long-term efficacy and safety of RSD in patients with hypertension. 相似文献11.

Background
The optimal noninvasive test (NIT) for patients with diabetes and stable symptoms of coronary artery disease (CAD) is unknown.Objectives
The purpose of this study was to assess whether a diagnostic strategy based on coronary computed tomographic angiography (CTA) is superior to functional stress testing in reducing adverse cardiovascular (CV) outcomes (CV death or myocardial infarction [MI]) among symptomatic patients with diabetes.Methods
PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) was a randomized trial evaluating an initial strategy of CTA versus functional testing in stable outpatients with symptoms suggestive of CAD. The study compared CV outcomes in patients with diabetes (n = 1,908 [21%]) and without diabetes (n = 7,058 [79%]) based on their randomization to CTA or functional testing.Results
Patients with diabetes (vs. without) were similar in age (median 61 years vs. 60 years) and sex (female 54% vs. 52%) but had a greater burden of CV comorbidities. Patients with diabetes who underwent CTA had a lower risk of CV death/MI compared with functional stress testing (CTA: 1.1% [10 of 936] vs. stress testing: 2.6% [25 of 972]; adjusted hazard ratio: 0.38; 95% confidence interval: 0.18 to 0.79; p = 0.01). There was no significant difference in nondiabetic patients (CTA: 1.4% [50 of 3,564] vs. stress testing: 1.3% [45 of 3,494]; adjusted hazard ratio: 1.03; 95% confidence interval: 0.69 to 1.54; p = 0.887; interaction term for diabetes p value = 0.02).Conclusions
In diabetic patients presenting with stable chest pain, a CTA strategy resulted in fewer adverse CV outcomes than a functional testing strategy. CTA may be considered as the initial diagnostic strategy in this subgroup. (PROspective Multicenter Imaging Study for Evaluation of Chest Pain [PROMISE]; NCT01174550) 相似文献12.

Background
Geographic factors may influence cardiovascular disease outcomes in Canada. Circulatory diseases are a major reason for higher population mortality rates in Northern Ontario, but it is unknown if hospitalized patients with cardiovascular disease experience differential outcomes compared with those in the South.Methods
We examined 30-day and 1-year mortality and readmissions for patients hospitalized with acute myocardial infarction (AMI), heart failure (HF), atrial fibrillation (AF), or stroke in Northern compared with Southern Ontario, using the Canadian Institute for Health Information Discharge Abstract Database (2005-2016). Northern patients were defined as those residing and hospitalized in the Northwest or Northeast Local Health Integration Network regions. We used multiple Cox proportional hazards regression analysis for time-to-first event and Prentice-Williams-Peterson method to evaluate repeat and multiply admitted patients.Results
A total of 47,745 Northern and 465,353 Southern patients hospitalized with AMI (n = 182,158), HF (n = 130,770), AF (n = 72,326), or stroke (n = 127,844) were studied. Rates of first readmission were higher among Northern patients for AMI (adjusted hazard ratio [HR], 1.32), HF (HR, 1.16), AF (HR, 1.21), and stroke (HR, 1.27) compared with Southern patients (all P < 0.001). Repeat readmission rates among Northern patients for AMI (HR, 1.23), HF (HR, 1.13), AF (HR, 1.18), and stroke (HR, 1.22) were also increased (all P < 0.001 vs Southern). Thirty-day mortality did not differ significantly between Northern and Southern patients.Conclusions
Readmissions were increased in those residing and hospitalized in the North. To reduce readmissions in the North, the quality of postacute transitional care should be examined further. 相似文献13.

Objectives
This study evaluated the safety and performance of the Paladin System, a novel angioplasty balloon with an integrated embolic protection filter designed to increase embolic protection during post-dilation.Background
The risk of major adverse events during carotid artery stenting (CAS) is equivalent to carotid endarterectomy. However, the risk of minor stroke remains higher with CAS. Much of this risk occurs during post-stent dilation.Methods
A total of 106 patients were enrolled in 5 centers in Germany. The study’s primary endpoint was all-cause death, myocardial infarction, and stroke at 30 days post-procedure. Pre- and post-procedural diffusion-weighted magnetic resonance imaging evaluated new ischemic lesions in 30 subjects. Filter histomorphometric analysis was performed in 23 patients. Retrospective analyses compared outcome rates to historical controls.Results
Device and procedural success rates were 100%. The combined major adverse event rate (death, myocardial infarction, and stroke) at discharge and at 30 days was 0% and 1.0%, respectively. The single adverse event was a stroke, which occurred at day 12 and was believed unrelated to the device or procedure. New ischemic lesions were found in 11 (36.7%) patients in the diffusion-weighted magnetic resonance imaging subset. New ipsilateral lesions were seen in 9 (30.0%) patients. Mean lesion volume per patient was 0.010 cm3. Debris was present in all filters, and approximately 90% of captured particles were <100 μm.Conclusions
Use of the Paladin System for post–stent dilation during CAS appears safe, and it may effectively decrease the number of embolic particles reaching the brain, which may help reduce the risk of procedure-related stroke.

Background
Cardiac rehabilitation (CR) intervention programs are currently not part of management in patients with atrial fibrillation (AF). We sought to determine the effect of CR compared with a specialized AF clinic (AFC) and usual care on outcomes in patients with AF.Methods
This was a single-centre retrospective cohort study that was carried out using 3 databases: the Hearts in Motion database (2010-2014), prospectively collected data in an AFC (2011-2014), and a retrospective chart review for patients in usual care (2009-2012). Three care pathways were compared: (1) CR; (2) AFC; and (3) usual specialist-based care. The main outcome was AF-related emergency department visits and cardiovascular hospitalizations.Results
Of 566 patients with newly diagnosed AF, 133 (23.5%) patients underwent CR, 197 patients (34.8%) attended the AFC, whereas the remaining 236 (41.7%) were followed in a usual specialist-based care clinic. At 1 year, AF-related emergency department visits and cardiovascular hospitalization rates occurred in 7.5% in the CR group, 16.8% in the AFC group, and 29.2% in usual care. After a propensity matched analysis, usual care was associated with the highest rate of the main outcome (odds ratio, 4.91; 95% confidence interval, 2.09-11.53) compared with CR, as did the AFC compared with CR (odds ratio, 2.75; 95% confidence interval, 1.14-6.6).Conclusions
Among patients with AF, CR was associated with a lower risk of AF-related outcomes. These findings support further study of the use of CR in the management of these patients to determine the optimal model of care for AF patients. 相似文献15.

Objectives
The aim of this study was to compare the thin-strut biodegradable-polymer everolimus-eluting platinum-chromium stent (EES) with the biodegradable-polymer biolimus-eluting stainless-steel stent (BES).Background
Currently available drug-eluting coronary stents have been refined to reduce the risk for coronary events following implantation.Methods
This randomized, multicenter, all-comers, noninferiority trial was undertaken at 3 sites in western Denmark. Patients with clinical indications for percutaneous coronary intervention were eligible for inclusion. Patients were randomly assigned (1:1) to either EES or BES. The primary endpoint, target lesion failure, was a composite of safety (cardiac death and myocardial infarction not clearly attributable to a nontarget lesion) and efficacy (target lesion revascularization) at 12 months, analyzed using intention-to-treat principles. The trial was powered to assess target lesion failure noninferiority of the EES compared with the BES with a predetermined noninferiority margin of 3%.Results
A total of 1,385 patients were assigned to treatment with EES and 1,369 patients to treatment with BES. The analysis showed that 55 patients (4.0%) assigned to the EES and 60 (4.4%) assigned to the BES met the primary endpoint (absolute risk difference 0.4%; upper limit of 1-sided 95% confidence interval: 1.7%; p < 0.001).Conclusions
At 1-year follow-up, the EES was found to be noninferior to the BES with respect to target lesion failure. (Everolimus-eluting SYNERGY Stent Versus Biolimus-Eluting Biomatrix NeoFlex Stent—SORT-OUT VIII; NCT02093845) 相似文献16.

Background
The randomized EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial reported a similar rate of the 3-year composite primary endpoint of death, myocardial infarction (MI), or stroke in patients with left main coronary artery disease (LMCAD) and site-assessed low or intermediate SYNTAX scores treated with percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). Whether these results are consistent in high-risk patients with diabetes, who have fared relatively better with CABG in most prior trials, is unknown.Objectives
In this pre-specified subgroup analysis from the EXCEL trial, the authors sought to examine the effect of diabetes in patients with LMCAD treated with PCI versus CABG.Methods
Patients (N = 1,905) with LMCAD and site-assessed low or intermediate CAD complexity (SYNTAX scores ≤32) were randomized 1:1 to PCI with everolimus-eluting stents versus CABG, stratified by the presence of diabetes. The primary endpoint was the rate of a composite of all-cause death, stroke, or MI at 3 years. Outcomes were examined in patients with (n = 554) and without (n = 1,350) diabetes.Results
The 3-year composite primary endpoint was significantly higher in diabetic compared with nondiabetic patients (20.0% vs. 12.9%; p < 0.001). The rate of the 3-year primary endpoint was similar after treatment with PCI and CABG in diabetic patients (20.7% vs. 19.3%, respectively; hazard ratio: 1.03; 95% confidence interval: 0.71 to 1.50; p = 0.87) and nondiabetic patients (12.9% vs. 12.9%, respectively; hazard ratio: 0.98; 95% confidence interval: 0.73 to 1.32; p = 0.89). All-cause death at 3 years occurred in 13.6% of PCI and 9.0% of CABG patients (p = 0.046), although no significant interaction was present between diabetes status and treatment for all-cause death (p = 0.22) or other endpoints, including the 3-year primary endpoint (p = 0.82) or the major secondary endpoints of death, MI, or stroke at 30 days (p = 0.61) or death, MI, stroke, or ischemia-driven revascularization at 3 years (p = 0.65).Conclusions
In the EXCEL trial, the relative 30-day and 3-year outcomes of PCI with everolimus-eluting stents versus CABG were consistent in diabetic and nondiabetic patients with LMCAD and site-assessed low or intermediate SYNTAX scores.(Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization [EXCEL]; NCT01205776) 相似文献17.

Background
Perihilar cholangiocarcinoma (PHC) often requires extensive surgery which is associated with substantial morbidity and mortality. This study aimed to compare an Eastern and Western PHC cohort in terms of patient characteristics, treatment strategies and outcomes including a propensity score matched analysis.Methods
All consecutive patients who underwent combined biliary and liver resection for PHC between 2005 and 2016 at two Western and one Eastern center were included. The overall perioperative and long-term outcomes of the cohorts were compared and a propensity score matched analysis was performed to compare perioperative outcomes.Results
A total of 210 Western patients were compared to 164 Eastern patients. Western patients had inferior survival compared to the East (hazard-ratio 1.72 (1-23-2.40) P < 0.001) corrected for age, ASA score, tumor stage and margin status. After propensity score matching, liver failure rate, morbidity, and mortality were similar. There was more biliary leakage (38% versus 13%, p = 0.015) in the West.Conclusion
There were major differences in patient characteristics, treatment strategies, perioperative outcomes and survival between Eastern and Western PHC cohorts. Future studies should focus whether these findings are due to the differences in the treatment or the disease itself. 相似文献18.

Objectives
Given the uncertainty regarding the degree and prevalence of spontaneous healing following spontaneous coronary artery dissection (SCAD), the aim of this study was to assess the angiographic characteristics of the dissected segments in a large cohort of patients with SCAD who underwent subsequent repeat coronary angiography.Background
SCAD is an uncommon yet important cause of myocardial infarction in women. Very little is known about the characteristics of healing of dissected arteries.Methods
Patients with nonatherosclerotic SCAD followed prospectively at Vancouver General Hospital who underwent repeat angiography were included in this study. Those who underwent percutaneous coronary intervention for SCAD were excluded. Baseline patient demographics and in-hospital and long-term cardiovascular events were recorded. Angiographic characteristics of the SCAD artery at index and repeat angiography were assessed by 2 experienced angiographers. Criteria for angiographic healing were as follows: 1) improvement of stenosis severity from index event; 2) residual stenosis <50%; and 3) TIMI (Thrombolysis In Myocardial Infarction) flow grade 3.Results
One hundred fifty-six patients with 182 noncontiguous SCAD lesions were included. The mean age was 51.5 ± 8.7 years, 88.5% were women, 83.3% were Caucasian, and 75.6% had fibromuscular dysplasia. All patients presented with myocardial infarction. At index angiography, type 2 SCAD was most commonly observed, in 126 of 182 lesions (69.2%); TIMI flow grade <3 was present in 85 of 182 (46.7%); and median lesion stenosis was 79.0% (interquartile range: 56.0% to 100%). Median time to repeat angiography was 154 days (interquartile range: 70 to 604 days), with median residual lesion stenosis improving to 25.5% (interquartile range: 12.0 to 38.8 days), and TIMI flow grade <3 observed in 10 of 182 lesions (5.5%). Angiographic healing occurred in 157 of 182 lesions (86.3%). Of repeat angiography performed ≥30 days post-SCAD, 152 of 160 (95%) showed spontaneous angiographic healing.Conclusions
The majority of coronary arteries affected by SCAD heal spontaneously on repeat angiography, with apparent time dependency, with the vast majority having complete healing after 30 days from the SCAD event. 相似文献19.

Objectives
The aim of this study was to determine whether individual operator characteristics have an impact on reperfusion and procedural complication rates.Background
Mechanical thrombectomy (MT) is a Level IA treatment in acute ischemic stroke (AIS) patients. The operator’s effect has been found to be an independent predictor for clinical outcome and technical performance in interventional cardiology.Methods
From the ETIS (Endovascular Treatment in Ischemic Stroke) study, a prospective, multicenter, observational real-world MT registry, the authors included all AIS patients consecutively treated by MT between January 2012 and March 2017 in 3 high-volume comprehensive stroke centers by 19 operators. We assessed the effect of individual operator characteristics on successful reperfusion, defined as modified Thrombolysis In Cerebral Infarction 2b/3 at the end of MT, and procedural complications using multivariable hierarchical logistic regression models.Results
A total of 1,541 patients with anterior and posterior AIS were enrolled (mean age 67 years; median NIHSS 16). There was a significant operator effect on successful reperfusion, with an intraclass correlation coefficient of 0.036 (p = 0.046), but not on complications (intraclass correlation coefficient = 0). There was a dose–response relationship between annual operator volume and successful reperfusion rate (p = 0.003) with an adjusted odds ratio for successful reperfusion equal to 2.52 (95% confidence interval: 1.37 to 4.64) for patients treated by an operator with an annual volume ≥40 MT/year compared with those treated by an operator with <14 MT/year (first tertile). Nevertheless, this result did not translate to better clinical outcomes.Conclusions
Our data suggest that operator volume of MT/year has a positive impact on successful reperfusion in AIS patients, but not on clinical outcomes nor on complication rates. Further studies are warranted to investigate threshold procedure numbers associated with better outcomes. 相似文献20.
