ABSTRACT
BACKGROUND: In patients with symptomatic heart failure, sacubitril-valsartan has been found to reduce the risk of hospitalization and death from cardiovascular causes more effectively than an angiotensin-converting-enzyme inhibitor. Trials comparing the effects of these drugs in patients with acute myocardial infarction have been lacking. METHODS: We randomly assigned patients with myocardial infarction complicated by a reduced left ventricular ejection fraction, pulmonary congestion, or both to receive either sacubitril-valsartan (97 mg of sacubitril and 103 mg of valsartan twice daily) or ramipril (5 mg twice daily) in addition to recommended therapy. The primary outcome was death from cardiovascular causes or incident heart failure (outpatient symptomatic heart failure or heart failure leading to hospitalization), whichever occurred first. RESULTS: A total of 5661 patients underwent randomization; 2830 were assigned to receive sacubitril-valsartan and 2831 to receive ramipril. Over a median of 22 months, a primary-outcome event occurred in 338 patients (11.9%) in the sacubitril-valsartan group and in 373 patients (13.2%) in the ramipril group (hazard ratio, 0.90; 95% confidence interval [CI], 0.78 to 1.04; P = 0.17). Death from cardiovascular causes or hospitalization for heart failure occurred in 308 patients (10.9%) in the sacubitril-valsartan group and in 335 patients (11.8%) in the ramipril group (hazard ratio, 0.91; 95% CI, 0.78 to 1.07); death from cardiovascular causes in 168 (5.9%) and 191 (6.7%), respectively (hazard ratio, 0.87; 95% CI, 0.71 to 1.08); and death from any cause in 213 (7.5%) and 242 (8.5%), respectively (hazard ratio, 0.88; 95% CI, 0.73 to 1.05). Treatment was discontinued because of an adverse event in 357 patients (12.6%) in the sacubitril-valsartan group and 379 patients (13.4%) in the ramipril group. CONCLUSIONS: Sacubitril-valsartan was not associated with a significantly lower incidence of death from cardiovascular causes or incident heart failure than ramipril among patients with acute myocardial infarction.

BACKGROUND: Polymer-free drug-coated stents provide superior clinical outcomes to bare-metal stents in patients at high bleeding risk who undergo percutaneous coronary intervention (PCI) and are treated with 1 month of dual antiplatelet therapy. Data on the use of polymer-based drug-eluting stents, as compared with polymer-free drug-coated stents, in such patients are limited. METHODS: In an international, randomized, single-blind trial, we compared polymer-based zotarolimus-eluting stents with polymer-free umirolimus-coated stents in patients at high bleeding risk. After PCI, patients were treated with 1 month of dual antiplatelet therapy, followed by single antiplatelet therapy. The primary outcome was a safety composite of death from cardiac causes, myocardial infarction, or stent thrombosis at 1 year. The principal secondary outcome was target-lesion failure, an effectiveness composite of death from cardiac causes, target-vessel myocardial infarction, or clinically indicated target-lesion revascularization. Both outcomes were powered for noninferiority. RESULTS: A total of 1996 patients at high bleeding risk were randomly assigned in a 1:1 ratio to receive zotarolimus-eluting stents (1003 patients) or polymer-free drug-coated stents (993 patients). At 1 year, the primary outcome was observed in 169 of 988 patients (17.1%) in the zotarolimus-eluting stent group and in 164 of 969 (16.9%) in the polymer-free drug-coated stent group (risk difference, 0.2 percentage points; upper boundary of the one-sided 97.5% confidence interval [CI], 3.5; noninferiority margin, 4.1; P = 0.01 for noninferiority). The principal secondary outcome was observed in 174 patients (17.6%) in the zotarolimus-eluting stent group and in 169 (17.4%) in the polymer-free drug-coated stent group (risk difference, 0.2 percentage points; upper boundary of the one-sided 97.5% CI, 3.5; noninferiority margin, 4.4; P = 0.007 for noninferiority). CONCLUSIONS: Among patients at high bleeding risk who received 1 month of dual antiplatelet therapy after PCI, use of polymer-based zotarolimus-eluting stents was noninferior to use of polymer-free drug-coated stents with regard to safety and effectiveness composite outcomes.

Background: We present an analysis that compares aortic morphological and clinical outcomes of 36 patients, all treated with endovascular uncovered stents implantation preceded or not by stent-graft implantation, or surgical treatment in the context of complex treatment of type A or type B aortic dissection. Methods: Between 2014 and 05/2018 our team treated 36 patients with acute aortic dissection and end-organ ischemia due to true lumen compression. All clinical and periprocedural data were obtained prospectively, followed by a retrospective analysis. The case series aim is to show induction of aortic remodeling by depressurization of the false lumen and increasing the size of the true lumen by non-covered stents implantation in the aorta and its affected side branches. Secondary endpoints were survival, branch patency, true lumen and false lumen size evolution. Results: Results from the diameter of both lumens measured by computed tomography angiography (CTA) before and at least 1 year after the treatment showed statistically significant differences, patent stents, as well as symptomatic improvement in all patients. Both aorta-related and general mortality in this complex group of patients was 0%. Conclusions: The concept of redirection of flow in aortic dissection with non-covered stents was safe, led to positive aorta remodeling and resulted in excellent survival rate.
ABSTRACT
BACKGROUND: Since the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from China, the novel coronavirus disease 2019 (COVID-19) has caused more than five milion deaths worldwide. Several studies have elucidated the role of risk factors in the prognosis of cardiovascular disease (CVD) in the progression of COVID-19 pandemic. This systematic review assesses the link between COVID-19 and cardiovascular risk factors, and investigates the prognosis in the case of myocardial injury. METHODS: A literature search was performed to identify relevant articles in Pubmed, MEDLINE, Elsevier, and Google Scholar the last two years using the terms: COVID-19, CVD, risk factors, cardiovascular risk factors, SARS-CoV-2, lockdown, hypertension, and diabetes mellitus. Exclusion criteria were the studies associated with pediatric and pregnant COVID-19 patients. RESULTS: After screening through 3071 articles, 10 studies were included in this review that captured the findings from 3912 participants. Included studies found that preexisting CVD was linked to worse outcomes and increased risk of death in patients with COVID-19, whereas COVID-19 itself also induced myocardial injury, arrhythmia, acute coronary syndrome, and venous thromboembolism. CONCLUSIONS: Cardiovascular risk factors such as hypertension, diabetes mellitus, and obesity were associated with intensive care unit admission and poor prognosis. Cardiovascular risk factors are crucial for the progression of COVID-19, and infected patients should be constantly monitored and follow strict hygiene and decrease their social interactions.

OBJECTIVES: The PERFORMANCE I study was designed to evaluate the safety and feasibility of the Neuroguard IEP® System, a novel carotid stent system with an integrated embolic filter and post-dilatation balloon, to treat clinically significant carotid artery stenosis. BACKGROUND: The risk of major adverse events during carotid artery stenting is comparable to carotid endarterectomy, however, the risk of minor stroke remains higher with stenting. METHODS: In total, 67 patients undergoing carotid artery stenting were enrolled at nine centers in Europe. Follow-up assessments included neurological exams, duplex ultrasound, 12-lead electrocardiogram, and cardiac enzyme analysis. The primary endpoint was the 30-day composite rate of stroke, death, and myocardial infarctions versus a prespecified performance goal. Secondary endpoints included procedure success, device success, and target lesion revascularization. RESULTS: The study population was predominantly male (74.6%) with a mean age of 69.3 ± 8.9 years and 67% of subjects met at least one criterion placing them at an elevated risk for adverse events following carotid endarterectomy. All patients were treated successfully with the study device. There were no deaths or strokes within 30 days of the index procedure. One subject (1.5%) experienced a non-ST elevation myocardial infarction at day 17. The primary endpoint was met with a 30-day major adverse events rate of 1.5% (1/67). Through 12-month follow-up, there were no strokes, neurological deaths, target lesion revascularizations, or instances of in-stent-restenosis. CONCLUSIONS: Results from this study demonstrate the Neuroguard IEP system is safe and feasible with a stroke/death rate of 0% at 30 days. A large pivotal study is currently underway.

Aortic aneurysm is an enlargement of the aorta with a loss of the arterial wall parallelism. There are several possible causes concerning etiology, one of which is the postsurgical presence of a patent distal false lumen. An aortic aneurysm is mainly seen after a surgery for type A aortic dissection and it represents an important late complication. Even more, in some cases the abdominal aortic aneurysm could be complicated by a patent distal false lumen, which makes it challenging for further treatment. We present a case of a 44-year-old male patient with Marfan syndrome and the history of a surgical repair of type A aortic dissection. He was diagnosed with a large abdominal aortic aneurysm and patent distal false lumen. In this report, we describe our technique and the outcome for endovascular fenestration of the persistent intimal flap and the stent-graft implantation for abdominal aortic aneurysm isolation after the surgery for aortic dissection type A. Our technique presents a novelty approach to patients with abdominal aortic aneurysm, complicated with a patent distal false lumen.

BACKGROUND: Supraflex is a sirolimus-eluting stent with a biodegradable polymer coating and ultra-thin struts. We aimed to compare Supraflex with the standard of care, Xience, an everolimus-eluting stent with a durable polymer coating, regarding clinical outcomes with a randomised trial in an all-comer population. METHODS: We did a prospective, randomised, single-blind, multicentre study (TALENT) across 23 centres in Europe (the Netherlands, Poland, the UK, Spain, Bulgaria, Hungary, and Italy). Eligible participants were aged 18 years or older, had one or more coronary artery stenosis of 50% or greater in a native coronary artery, saphenous venous graft, or arterial bypass conduit, and had a reference vessel diameter of 2·25-4·50 mm. Patients underwent percutaneous coronary intervention in an all-comer manner. We randomly assigned patients (1:1) to implantation of either a sirolimus-eluting stent with a biodegradable polymer coating and ultra-thin struts (Supraflex) or an everolimus-eluting stent with a durable polymer coating (Xience). Randomisation was done by local investigators by use of a web-based software with random blocks according to centre. The primary endpoint was a non-inferiority comparison of a device-oriented composite endpoint-cardiac death, target-vessel myocardial infarction, or clinically indicated target lesion revascularisation-between groups at 12 months after the procedure, assessed in an intention-to-treat population. On assumption of 1-year composite endpoint prevalence of 8·3%, a margin of 4·0% was defined for non-inferiority of the Supraflex group compared with the Xience group. This trial is registered with ClinicalTrials.gov, number NCT02870140. FINDINGS: Between Oct 21, 2016, and July 3, 2017, 1435 patients with 1046 lesions were randomly assigned to Supraflex, of whom 720 received the index procedure, and 715 patients with 1030 lesions were assigned to Xience, all receiving the index procedure. At 12 months, the primary endpoint had occurred in 35 patients (4·9 %) in the Supraflex group and in 37 patients (5·3%) in the Xience group (absolute difference -0·3% [one-sided 95% upper confidence bound 1·6%], pnon-inferiority<0·0001). Definite or probable stent thrombosis prevalence, a safety indicator, was low in both groups and did not differ between them. INTERPRETATION: The Supraflex stent was non-inferior to the Xience stent for a device-oriented composite clinical endpoint at 12 months in an all-comer population. Supraflex seems a safe and effective alternative drug-eluting stent to other stents in clinical practice. FUNDING: European Cardiovascular Research Institute.

AIMS: Cardiopoietic cells, produced through cardiogenic conditioning of patients' mesenchymal stem cells, have shown preliminary efficacy. The Congestive Heart Failure Cardiopoietic Regenerative Therapy (CHART-1) trial aimed to validate cardiopoiesis-based biotherapy in a larger heart failure cohort. METHODS AND RESULTS: This multinational, randomized, double-blind, sham-controlled study was conducted in 39 hospitals. Patients with symptomatic ischaemic heart failure on guideline-directed therapy (n = 484) were screened; n = 348 underwent bone marrow harvest and mesenchymal stem cell expansion. Those achieving > 24 million mesenchymal stem cells (n = 315) were randomized to cardiopoietic cells delivered endomyocardially with a retention-enhanced catheter (n = 157) or sham procedure (n = 158). Procedures were performed as randomized in 271 patients (n = 120 cardiopoietic cells, n = 151 sham). The primary efficacy endpoint was a Finkelstein-Schoenfeld hierarchical composite (all-cause mortality, worsening heart failure, Minnesota Living with Heart Failure Questionnaire score, 6-min walk distance, left ventricular end-systolic volume, and ejection fraction) at 39 weeks. The primary outcome was neutral (Mann-Whitney estimator 0.54, 95% confidence interval [CI] 0.47-0.61 [value > 0.5 favours cell treatment], P = 0.27). Exploratory analyses suggested a benefit of cell treatment on the primary composite in patients with baseline left ventricular end-diastolic volume 200-370 mL (60% of patients) (Mann-Whitney estimator 0.61, 95% CI 0.52-0.70, P = 0.015). No difference was observed in serious adverse events. One (0.9%) cardiopoietic cell patient and 9 (5.4%) sham patients experienced aborted or sudden cardiac death. CONCLUSION: The primary endpoint was neutral, with safety demonstrated across the cohort. Further evaluation of cardiopoietic cell therapy in patients with elevated end-diastolic volume is warranted.

BACKGROUND: Familial hypercholesterolaemia (FH) is a genetic disorder causing accelerated atherosclerosis and premature cardiovascular disease (CVD). This retrospective observational study examined the clinical characteristics and management of FH subjects in Bulgaria over a 12-month period. MATERIALS AND METHODS: Twelve cardiology sites participated in this study from May 2015 to May 2016. Eligible subjects had at least two routine low-density lipo-protein cholesterol (LDL C) measurements and a prescription for lipid-lowering therapy (LLT) at the start of the observation period. Mean values for gender, age and cardiovascular (CV) event history at baseline and LDL-C over time were estimated. RESULTS: Of the 220 eligible subjects, 196 fulfilled the criteria for FH diagnosis: 27 definite, 94 probable and 75 possible. Mean age at enrolment was 54.4 years and 64.1% of subjects were male. Mean CV risk classification at baseline was 26.8% high-risk (HR) and 73.2% very high-risk (VHR). Mean LDL-C was 5.6 mmol/L at enrolment and 4.1 mmol/L at last observation visit (12 months). The ESC/EAS Guideline LDL-C targets (applicable at the time of the study) were achieved by 14.5% of HR and 5.0% of VHR subjects. Most subjects (n=219) received statins. One subject was statin intolerant (ezetimibe therapy). Intensive statin treatment (atorvastatin 40-80 mg/daily and rosuvastatin 20-40 mg/daily) was used in 38.6% of individuals during the observation period and 10% of subjects received combination therapy (statin plus ezetimibe or other LLT). CONCLUSIONS: Most subjects with FH do not reach the ESC/EAS defined LDL-C targets. Early identification and physician education may improve FH management.

OBJECTIVE: Interventional treatments for acute iliofemoral deep vein thrombosis (DVT) remain controversial after publication of the Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter-Directed Thrombolysis (ATTRACT) study. Interventions have been shown to reduce post-thrombotic syndrome severity and improve quality of life in DVT patients, but have been accompanied by risk of major bleeding from thrombolytics. We describe thrombus removal using a novel combined basket-rotational thrombectomy device that minimizes the need for thrombolytics or repeat procedures. METHODS: The aim of this prospective, nonrandomized, multicenter, first-in-human study of 19 patients with acute iliofemoral DVT was to evaluate the safety and performance of the Pounce venous thrombectomy system ≤12 months after treatment. The primary performance end point was defined as procedural success through achievement of Society of Interventional Radiology (SIR) grade II lysis in treated vessels with freedom from procedural adverse events. Secondary end points included venous disease severity assessments using the Villalta scale and the Venous Clinical Severity Score, patient quality-of-life measurement using the Venous Insufficiency Epidemiological and Economic Study-Quality of Life questionnaire, and calf circumference measurements taken at baseline, 24 hours, and 1 month. RESULTS: The primary end point of complete or near-complete thrombus removal (Society of Interventional Radiology grade II or III) was achieved in all patients. All study device-related safety end points were met, with no major bleeding or device-related adverse events. Of the 19 patients treated, 16 (84.2%) did not receive thrombolytics during the procedure. Post-thrombotic syndrome (Villalta scale >4) was identified in 17 of 19 patients (89.5%) at baseline, 4 of 13 patients (30.8%) available for follow-up at 6 months, and 2 of 11 patients (18.2%) at 12 months. The median Venous Clinical Severity Score decreased (P < .001) from 8.5 (interquartile range [IQR], 7-10) at baseline to 4 (IQR, 2-4) at 1 month after the procedure and was similar at 6 months (2; IQR, 2-5) and 12 months (2; IQR, 1.5-3) after the procedure. The median Venous Insufficiency Epidemiological and Economic Study-Quality of Life questionnaire score improved (P < .001) by 39 from baseline (57; IQR, 53.5-74) to 1 month (96; IQR, 86-101) after the procedure, and remained high at 6 months (99; IQR, 75-103) and 12 months (98; IQR, 94.5-100). The median calf circumference decreased (P = .089) from 39 cm (IQR, 35-47.8 cm) at baseline to 36 cm (IQR, 32.5-40.5 cm) at 24 hours after the procedure and was 34.5 cm (IQR, 33.2-38.5 cm) at 1 month. CONCLUSIONS: The Pounce device is safe and effective for removal the of thrombus in patients with acute iliofemoral DVT. Initial results demonstrate improvements in venous disease severity and patient quality of life.
ABSTRACT
IMPORTANCE: The optimal anticoagulant for patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) managed with an invasive strategy remains controversial. OBJECTIVE: To compare the clinical efficacy and safety of otamixaban, a novel intravenous direct factor Xa inhibitor, with that of unfractionated heparin plus downstream eptifibatide in patients with NSTE-ACS undergoing a planned early invasive strategy. DESIGN, SETTING, AND PARTICIPANTS: Randomized, double-blind, active-controlled superiority trial that enrolled 13,229 patients with NSTE-ACS and a planned early invasive strategy, at 568 active sites in 55 countries and conducted between April 2010 and February 2013. A planned interim analysis was conducted for otamixaban dose selection. INTERVENTIONS: Eligible participants were randomized to otamixaban (bolus and infusion, at 1 of 2 doses) or unfractionated heparin plus, at the time of percutaneous coronary intervention, eptifibatide. The otamixaban dose selected at interim analysis was an intravenous bolus of 0.080 mg/kg followed by an infusion of 0.140 mg/kg per hour. MAIN OUTCOMES AND MEASURES: The primary efficacy outcome was the composite of all-cause death or new myocardial infarction through day 7. RESULTS: Rates of the primary efficacy outcome were 5.5% (279 of 5105 patients) randomized to receive otamixaban and 5.7% (310 of 5466 patients) randomized to receive unfractionated heparin plus eptifibatide (adjusted relative risk, 0.99 [95% CI, 0.85-1.16]; P = .93). There were no differences for the secondary end points, including procedural thrombotic complications. The primary safety outcome of Thrombosis in Myocardial Infarction major or minor bleeding through day 7 was increased by otamixaban (3.1% vs 1.5%; relative risk, 2.13 [95% CI, 1.63-2.78]; P < .001). Results were consistent across prespecified subgroups. CONCLUSIONS AND RELEVANCE: Otamixaban did not reduce the rate of ischemic events relative to unfractionated heparin plus eptifibatide but did increase bleeding. These findings do not support the use of otamixaban for patients with NSTE-ACS undergoing planned early percutaneous coronary intervention.

INTRODUCTION: Carotid stenting is used with an expanding indications. The neurotrophins are a family of proteins that induce the survival, development, and function of neurons. Carotid stenting alters cerebral blood flow and can affect neurotrophins' levels. MATERIAL AND METHODS: We included 78 people: 39 with significant carotid stenoses (CS) referred for carotid stenting (mean age 67.79 ± 10.53 years) and relatively healthy control group of 39 people without carotid and vertebral artery disease (mean age 57.42 ± 15.77 years). Brain derived reurotrophic factor (BDNF) and neuronal growth factor (NGF) concentrations were evaluated with ELISA method from venous blood - once for the control group; and for the carotid stenting group: before (n33), 24 h after (n22) and at least 1 month after (n18) carotid stenting. RESULTS: There was a difference between the mean neurotrophins' concentration of patients with significant carotid stenoses and the group without: BDNF p = 0.001, CI (-5.11 to -1.44) (3.10 ± 3.10 ng/ml in CS vs. 6.37 ± 4.67 ng/ml in controls); NGF p = 0.049, CI (0.64-347.75), 195.67 ± 495.34 pg/ml in CS vs. 21.48 ± 52.81 pg/ml in controls. BDNF levels before carotid stenting (3.10 ± 3.10 ng/ml) were significantly lower than the postprocedural (4.99 ± 2.57 ng/ml) - p < 0.0001, CI (-2.86 to -0.99). For NGF there was a tendency for lower values after stenting: 195.67 ± 495.34 pg/ml before vs. 94.92 ± 120.06 pg/ml after, but the result did not reach statistical significance. The neurotrophins levels one month after carotid stenting and controls' were not significantly different p < 0.01 (BDNF 5.03 ± 4.75 ng/ml vs. 6.37 ± 4.67 ng/min; NGF 47.89 ± 54.68 pg/ml vs. 21.48 pg/ml). DISCUSSION AND CONCLUSION: Periprocedural and mid-term concentrations of neurotrophins after carotid stenting change in non-linear model. This may be due to changes in cerebral perfusion and also might be involved in neuronal recovery and reparation after reperfusion.KEY MESSAGESPeriprocedural and mid-term concentrations of neurotrophins after carotid stenting change in non-linear model.As the majority of them are not specific, their periprocedural change can be used as a clinical correlate to guide changes or even success in carotid stenting.Changes in neutrophins' concentrations may be due to changes in cerebral perfusion and also might be involved in neuronal recovery and reparation after reperfusion.This goes in analogy with cardiac high-sensitive troponin, used as procedural guidance in coronary interventions.

INTRODUCTION: Carotid stenting may produce significant bradycardia and/or hypotension. This may have negative short- and long-term effects for the elderly high-risk patients. Their cerebral hemodynamics is with exhausted adaptive capacity because of the multiple cardiovascular risk factors, advanced age, and significant stenosis.

Purpose: We examined clinical characteristics and low-density lipoprotein cholesterol (LDL-C) lowering in patients initiating evolocumab in real-world practice in a Central and Eastern European (CEE) cohort from the pan-European HEYMANS study. Methods: Patients from Bulgaria, Czech Republic, and Slovakia were enrolled at initiation of evolocumab (baseline) as per local reimbursement criteria. Demographic/clinical characteristics, lipid-lowering therapy (LLT) and lipid values were collected from medical records for ≤6 months before baseline and ≤30 months after evolocumab initiation. Results: Overall, 333 patients were followed over a mean (SD) duration of 25.1 (7.5) months. At initiation of evolocumab, LDL-C levels were markedly elevated in all three countries, with a median (Q1, Q3) LDL-C of 5.2 (4.0, 6.6) mmol/L in Bulgaria, 4.5 (3.8, 5.8) mmol/L in the Czech Republic, and 4.7 (4.0, 5.6) mmol/L in Slovakia. Within the first three months of evolocumab treatment, LDL-C levels were reduced by a median of 61% in Bulgaria, 64% in the Czech Republic, and 53% in Slovakia. LDL-C levels remained low throughout the remaining period of observation. The 2019 ESC/EAS guideline-recommended risk-based LDL-C goals were attained by 46% of patients in Bulgaria, 59% in the Czech Republic, and 43% of patients in Slovakia. LDL-C goal attainment was higher in patients receiving a statin ± ezetimibe-based background therapy (Bulgaria: 55%, Czech Republic: 71%, Slovakia: 51%) compared to those receiving evolocumab alone (Bulgaria: 19%, Czech Republic: 49%, Slovakia: 34%). Conclusion: In the HEYMANS CEE cohort, patients initiated on evolocumab had baseline LDL-C levels approximately three-fold higher than guideline-recommended thresholds for PCSK9i initiation. Risk-based LDL-C goal attainment was highest in patients receiving high-intensity combination therapy. Lowering the LDL-C reimbursement threshold for PCSK9i initiation would allow more patients to receive combination therapy, thus improving LDL-C goal attainment.

AIMS: 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. METHODS AND RESULTS: 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. CONCLUSIONS: In a population of patients with diabetes and stable coronary artery disease, a sizeable proportion appear to be 'THEMIS eligible.' CLINICAL TRIAL REGISTRATION: http://www.

BACKGROUND: Optimal duration of dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI) of a bifurcation stenosis is still debated. We evaluated the impact of DAPT duration on clinical outcomes in all-comers patients undergoing bifurcation PCI included in the European Bifurcation Club (EBC) registry. METHODS: We enrolled 2284 consecutive patients who completed at least 18 months follow-up. The cumulative occurrence of major adverse cardiac and cardiovascular events (MACCE), defined as a composite of overall-death, non-fatal myocardial infarction (MI), target vessel revascularization (TVR) and stroke were evaluated. Bleedings classified as Bleeding Academic Research Consortium (BARC) ≥3 were evaluated too. RESULTS: Patients were divided into 3 groups: short DAPT (<6-months, N.=375); standard DAPT (≥6-months but ≤12-months, N.=636); prolonged DAPT (>12-months, N.=1273). At 24 months follow-up MACCE-free survival was significantly lower in short DAPT patients (Log-Rank: 45.23, P for trend <0.001). MACCE occurred less frequently in the prolonged DAPT group (148 [11.6%]) as compared with both the short (83 [22.1%] HR: 0.48 [0.37-0.63], P<0.001) and standard DAPT groups (137 [21.5%] HR:0.51 [0.41-0.65], P<0.001). These differences remain after propensity score adjustment (respectively, HR: 0.27 [0.20-0.36] and HR: 0.44 [0.34-0.57]). Such finding was consistent in patients presenting with both acute and chronic coronary syndromes. BARC≥3 bleedings were 0.3% in the standard DAPT, 1.6% in short and 1.9% in prolonged DAPT groups. CONCLUSIONS: In the "real-world" EBC registry of patients undergoing PCI of coronary artery bifurcation stenosis, a prolonged DAPT duration was associated with a significantly lower risk of MACCE and a potential increased risk of major bleedings.

Introduction: Today, endovascular treatment (EVT) is the therapy of choice for strokes due to acute large vessel occlusion, irrespective of prior thrombolysis. This necessitates fast, coordinated multi-specialty collaboration. Currently, in most countries, the number of physicians and centres with expertise in EVT is limited. Thus, only a small proportion of eligible patients receive this potentially life-saving therapy, often after significant delays. Hence, there is an unmet need to train a sufficient number of physicians and centres in acute stroke intervention in order to allow widespread and timely access to EVT. Aim: To provide multi-specialty training guidelines for competency, accreditation and certification of centres and physicians in EVT for acute large vessel occlusion strokes. Material and methods: The World Federation for Interventional Stroke Treatment (WIST) consists of experts in the field of endovascular stroke treatment. This interdisciplinary working group developed competency - rather than time-based - guidelines for operator training, taking into consideration trainees' previous skillsets and experience. Existing training concepts from mostly single specialty organizations were analysed and incorporated. Results: The WIST establishes an individualized approach to acquiring clinical knowledge and procedural skills to meet the competency requirements for certification of interventionalists of various disciplines and stroke centres in EVT. WIST guidelines encourage acquisition of skills using innovative training methods such as structured supervised high-fidelity simulation and procedural performance on human perfused cadaveric models. Conclusions: WIST multispecialty guidelines outline competency and quality standards for physicians and centres to perform safe and effective EVT. The role of quality control and quality assurance is highlighted.
