Extracellular Matrix Proteomics Reveals Interplay of Aggrecan and Aggrecanases in Vascular Remodeling of Stented Coronary Arteries. Circulation 2017; 137:166-183. [PMID: 29030347 PMCID: PMC5757669 DOI: 10.1161/circulationaha.116.023381] [Citation(s) in RCA: 72] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2016] [Accepted: 09/22/2017] [Indexed: 12/11/2022]
Abstract
Supplemental Digital Content is available in the text. Background: Extracellular matrix (ECM) remodeling contributes to in-stent restenosis and thrombosis. Despite its important clinical implications, little is known about ECM changes post–stent implantation. Methods: Bare-metal and drug-eluting stents were implanted in pig coronary arteries with an overstretch under optical coherence tomography guidance. Stented segments were harvested 1, 3, 7, 14, and 28 days post-stenting for proteomics analysis of the media and neointima. Results: A total of 151 ECM and ECM-associated proteins were identified by mass spectrometry. After stent implantation, proteins involved in regulating calcification were upregulated in the neointima of drug-eluting stents. The earliest changes in the media were proteins involved in inflammation and thrombosis, followed by changes in regulatory ECM proteins. By day 28, basement membrane proteins were reduced in drug-eluting stents in comparison with bare-metal stents. In contrast, the large aggregating proteoglycan aggrecan was increased. Aggrecanases of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) family contribute to the catabolism of vascular proteoglycans. An increase in ADAMTS-specific aggrecan fragments was accompanied by a notable shift from ADAMTS1 and ADAMTS5 to ADAMTS4 gene expression after stent implantation. Immunostaining in human stented coronary arteries confirmed the presence of aggrecan and aggrecan fragments, in particular, at the contacts of the stent struts with the artery. Further investigation of aggrecan presence in the human vasculature revealed that aggrecan and aggrecan cleavage were more abundant in human arteries than in human veins. In addition, aggrecan synthesis was induced on grafting a vein into the arterial circulation, suggesting an important role for aggrecan in vascular plasticity. Finally, lack of ADAMTS-5 activity in mice resulted in an accumulation of aggrecan and a dilation of the thoracic aorta, confirming that aggrecanase activity regulates aggrecan abundance in the arterial wall and contributes to vascular remodeling. Conclusions: Significant differences were identified by proteomics in the ECM of coronary arteries after bare-metal and drug-eluting stent implantation, most notably an upregulation of aggrecan, a major ECM component of cartilaginous tissues that confers resistance to compression. The accumulation of aggrecan coincided with a shift in ADAMTS gene expression. This study provides the first evidence implicating aggrecan and aggrecanases in the vascular injury response after stenting.

Abstract
INTRODUCTION We have recently seen the introduction of newer generation drug-eluting stents with ultrathin struts that use advanced polymer technologies. However, the efficacy and safety of these newest stents have not yet been fully explored. In addition, there are still controversies over the optimal duration of dual antiplatelet therapy (DAPT) after stent implantation, particularly for ultrathin stents with the newest polymer technologies. METHODS AND ANALYSIS The HOST-IDEA trial is a randomised, open-label, multicentre, non-inferiority trial and the first study to directly compare two of these ultrathin sirolimus-eluting stents: Orsiro stent with biodegradable polymer, and polymer-free Coroflex ISAR (CX-ISAR) stent. This study has a scheme of 2×2 factorial design according to the stent type and DAPT duration (3 vs 12 months). A total of 2152 patients will be randomised and stratified to demonstrate the non-inferiority of CX-ISAR to Orsiro, or of the abbreviated DAPT duration to the conventional 12 months (both in 1:1 ratio). For the comparison of stent type, the primary endpoint is target lesion failure (TLF), which is a composite of cardiac death, target vessel-related myocardial infarction and clinically driven target lesion revascularisation. For the comparison of DAPT duration, the net adverse clinical event is the coprimary endpoint, which is defined as a composite of TLF, definite/probable stent thrombosis and major bleeding. ETHIC APPROVAL AND DISSEMINATION All the institutions involved in this study are required to have ethical approval prior to patient enrolment. This multicentre study will recruit patients through competitive registration, but institutions that have not yet obtained ethical approvals have made it impossible to enrol patients in a centralised web database. The final results will be presented at relevant international conferences and will be materialised in the form of papers. TRIAL REGISTRATION NUMBER NCT02601157; Pre-results.

Second-generation drug-eluting stents versus drug-coated balloons for the treatment of coronary in-stent restenosis: A systematic review and meta-analysis.

Abstract
PURPOSE The benefit of drug-eluting stents (DES) versus drug-coated balloons (DCB) in coronary artery in-stent restenosis (ISR) for the prevention of target lesion revascularization (TLR), stent thrombosis, and mortality remains uncertain. Our aim was to synthesize the available evidence from randomized clinical trials (RCTs) and observational studies that directly compare second-generation drug-eluting stents (SG-DES) and DCB for the treatment of coronary ISR. METHODS Medline, Embase, and Cochrane Central were searched for RCTs or observational studies, published up to March 15, 2017. A random effects model meta-analysis investigating clinical and angiographic outcomes was conducted for RCTs and observational studies that compared SG-DES versus DCB for the treatment of ISR. RESULTS Ten studies and 2,173 patients were included in this meta-analysis. The two treatment strategies were proven equal with regards to TLR, myocardial infarction, stent thrombosis, and cardiac mortality in both randomized and observational studies. No difference was found among RCTs for all-cause mortality, while in observational studies, patients who were treated with SG-DES had a lower mortality compared to DCB (OR: 0.47; 95% CI: 0.27-0.83). In the pooled analysis also (RCTs and observational studies), SG-DES were associated with lower all-cause mortality compared to DCB. Patients treated with SG-DES were also superior in terms of minimal lumen diameter (standardized mean difference: 0.39; 95% CI: 0.12-0.66). CONCLUSIONS The two treatment strategies are equal for the treatment of ISR, while the difference in all-cause mortality might be potentially explained by baseline differences in the two groups among real-world studies.

Abstract
OBJECTIVES The aim of this study was to investigate the efficacy and safety of the hybrid ultrathin-strut sirolimus-eluting stent (SES) with biodegradable polymer compared with the thin-strut everolimus-eluting stent (EES) with durable polymer in successfully recanalized chronic total occlusions (CTOs). BACKGROUND The introduction of drug-eluting stents revolutionized the treatment of CTOs. However, limited data are available on new-generation drug-eluting stents with biodegradable polymer in CTOs. METHODS In this multicenter trial, patients were randomized, after successful CTO recanalization, to either SES or EES. The primary noninferiority endpoint was in-segment late lumen loss (noninferiority margin 0.2 mm). Secondary endpoints included in-stent late lumen loss and clinical endpoints. RESULTS Overall, 330 patients were included. At 9 months, angiography was available in 281 patients (85%). Duration of occlusion ≥3 months was 92.5%, with mean stent length of 52.4 ± 28.1 mm versus 52.3 ± 26.5 mm in the SES and EES groups. The primary noninferiority endpoint, in-segment late lumen loss, was not met for SES versus EES (0.13 ± 0.63 mm vs. 0.02 ± 0.47 mm; p = 0.08, 2-sided; difference 0.11 mm; 95% confidence interval: -0.01 to 0.25 mm; pnoninferiority = 0.11, 1-sided). In-stent late lumen loss was comparable between SES and EES (0.12 ± 0.59 mm vs. 0.07 ± 0.46 mm; p = 0.52). The incidence of in-stent and in-segment binary restenosis was significantly higher with SES compared with EES (8.0% vs. 2.1%; p = 0.028), with comparable rates of reocclusions (2.2% vs. 1.4%; p = 0.68). Clinically indicated target lesion and target vessel revascularization (9.2% vs. 4.0% [p = 0.08] and 9.2% vs. 6.0% [p = 0.33]), target vessel failure (9.9% vs. 6.6%; p = 0.35), and definite or probable stent thrombosis (0.7% vs. 0.7%; p = 1.00) were comparable between the SES and EES groups. CONCLUSIONS This randomized trial failed to show noninferiority of hybrid SES relative to EES in terms of in-segment late lumen loss in successfully recanalized CTOs. Furthermore, a statistically significantly higher rate of binary restenosis was found with SES.

Abstract
INTRODUCTION The findings of many new cardiology clinical trials over the last year have been published or presented at major international meetings. This paper aims to describe and place in context a summary of the key clinical trials in cardiology presented between January and December 2016. METHODS The authors reviewed clinical trials presented at major cardiology conferences during 2016 including the American College of Cardiology (ACC), European Association for Percutaneous Cardiovascular Interventions (EuroPCR), European Society of Cardiology (ESC), European Association for the Study of Diabetes (EASD), Transcatheter Cardiovascular Therapeutics (TCT), and the American Heart Association (AHA). Selection criteria were trials with a broad relevance to the cardiology community and those with potential to change current practice. RESULTS A total of 57 key cardiology clinical trials were identified for inclusion. Here we describe and place in clinical context the key findings of new data relating to interventional and structural cardiology including delayed stenting following primary angioplasty, contrast-induced nephropathy, management of jailed wires, optimal duration of dual antiplatelet therapy (DAPT), stenting vs bypass for left main disease, new generation stents (BioFreedom, Orsiro, Absorb), transcatheter aortic valve implantation (Edwards Sapien XT, transcatheter embolic protection), and closure devices (Watchman, Amplatzer). New preventative cardiology data include trials of bariatric surgery, empagliflozin, liraglutide, semaglutide, PCSK9 inhibitors (evolocumab and alirocumab), and inclisiran. Antiplatelet therapy trials include platelet function monitoring and ticagrelor vs clopidogrel for peripheral vascular disease. New data are also presented in fields of heart failure (sacubitril/valsartan, aliskiren, spironolactone), atrial fibrillation (rivaroxaban in patients undergoing coronary intervention, edoxaban in DC cardioversion), cardiac devices (implantable cardioverter defibrillator in non-ischemic cardiomyopathy), and electrophysiology (cryoballoon vs radiofrequency ablation). CONCLUSION This paper presents a summary of key clinical cardiology trials during the past year and should be of practical value to both clinicians and cardiology researchers.

Abstract
BACKGROUND Controversies have been observed among network meta-analyses comparing biodegradable polymer drug-eluting stents (BP-DES) with durable polymer drug-eluting stents (DP-DES). We aimed to compare the adverse cardiovascular events associated with BP-DES and durable polymer everolimus-eluting stents (DP-EES) using a large number of patients obtained from randomized controlled trials (RCTs). METHODS Electronic databases were searched for randomized trials comparing BP-DES with DP-EES. Adverse cardiovascular outcomes observed between 6 months and 3 years were considered as the clinical endpoints in this analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated and the pooled analyses were performed with RevMan 5.3 software. All authors had full access to the data, and they have read and agreed to the manuscript as written. RESULTS Ten trials involving a total number of 13,218 patients (7451 patients treated by BP-DES and 5767 patients treated by DP-EES) were included. No significant difference was observed when analyzing mortality and myocardial infarction between BP-DES and DP-EES with OR 1.08, 95% CI 0.87-1.34, P = .47 and OR 1.04, 95% CI 0.84-1.28, P = .72 respectively. Target vessel revascularization, target lesion revascularization, major adverse cardiac events, and stroke were also not significantly different with OR 1.11, 95% CI 0.92-1.33, P = .28; OR 1.11, 95% CI 0.94-1.33, P = .22; OR 1.12, 95% CI 0.99-1.27; P = .07; and OR 1.13, 95% CI 0.69-1.84; P = .62 respectively. In addition, total stent thrombosis (ST) was similarly reported between BP-DES and DP-EES with OR 0.85, 95% CI 0.59-1.21; P = .37. However, even if BP-DES were associated with a higher rate of definite ST with OR 1.69, 95% CI 0.92-3.08, P = .09 and DP-EES were associated with a higher rate of probable ST with OR 0.67, 95% CI 0.38-1.17, P = .16, these results were not statistically significant. CONCLUSIONS Between 6 months and 3 years, BP-DES were similar in terms of cardiovascular outcomes compared to DP-EES. However, further long-term follow-up research is recommended.

Abstract
INTRODUCTION AND OBJECTIVES New drug-eluting stents (DES) designed to overcome the limitations of existing devices should initially be tested in preclinical studies. Our objective was to analyze the safety and efficacy of new biodegradable polymer-based DES compared with bare-metal stents (BMS) and commercially available DES in a model of normal porcine coronary arteries. METHODS We randomly implanted 101 stents (BMS and biodegradable polymer-based sirolimus-eluting stents: 3 test stent iterations [BD1, BD2, and BD3], Orsiro, Biomime and Biomatrix) in the coronary arteries of 34 domestic pigs. Angiographic and histomorphometric studies were conducted 1 month (n = 83) and 3 months (n = 18) later. RESULTS The stents were implanted at a stent/artery ratio of 1.31 ± 0.21, with no significant differences between groups. At 1 month, the new test stents (BD1, BD2 and BD3) showed less late loss and angiographic restenosis, as well as lower histologic restenosis and neointimal area (P < .0005), than the BMS. There were no differences in endothelialization, vascular injury, or inflammation between the new test stents and BMS, although the new stents showed higher fibrin deposition (P = .0006). At 3 months, all these differences disappeared, except for a lower neointimal area with the new BD1 stent (P = .027). No differences at any time point were observed between the new test stents and commercially available controls. CONCLUSIONS In this preclinical model, the new biodegradable polymer-based DES studied showed less restenosis than BMS and no significant differences in safety or efficacy vs commercially available DES.

Abstract
Patients with percutaneous coronary intervention generally receive either bare metal stents or drug-eluting stents to restore the normal blood flow. However, due to the lack of stent production with an individual patient in mind, the same level of effectiveness may not be possible in treating two different clinical scenarios. This study introduces for the first time the feasibility of a patient-specific stenting process constructed from direct 3D segmentation of medical images using direct 3D printing of biodegradable polymer-graphene composite with dual drug incorporation. A biodegradable polymer-carbon composite is prepared doped with graphene nanoplatelets to achieve controlled release of combinatorics as anticoagulation and antirestenosis agents. This study develops a technology prototyped for personalized stenting. An in silico analysis is performed to optimize the stent design for printing and its prediction of sustainability under force exerted by coronary artery or blood flow. A holistic approach covering in silico to in situ-in vivo establishes the structural integrity of the polymer composite, its mechanical properties, drug loading and release control, prototyping, functional activity, safety, and feasibility of placement in coronary artery of swine.

Three-Year Clinical Outcome of Patients with Coronary Disease and Increased Event Risk Treated with Newer-Generation Drug-Eluting Stents: From the Randomized DUTCH PEERS Trial. Cardiology 2017; 137:207-217. [PMID: 28445871 DOI: 10.1159/000464320] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Accepted: 02/20/2017] [Indexed: 11/19/2022]
Abstract
OBJECTIVE Limited data is available on the long-term outcome of patients with increased cardiovascular event risk, treated with newer-generation durable polymer drug-eluting stents (DES). METHODS We therefore assessed 3-year follow-up data of high-risk versus low- to intermediate-risk patients of the randomized DUTCH PEERS trial (NCT01331707). In both risk groups we also compared patients treated with Resolute Integrity versus Promus Element DES. Patients were categorized as "high-risk" if they met ≥1 of the following criteria: (1) diabetes (17.9%); (2) previous myocardial infarction (21.9%); (3) previous coronary revascularization (25.8%); (4) chronic renal failure (3.5%); (5) left ventricular ejection fraction ≤30% (1.5%); and (6) age ≥75 years (17.3%). RESULTS At the 3-year follow-up, the incidence of the composite endpoint target vessel failure (TVF) (13.2 vs. 7.5%; logrank p < 0.001) and 2 of its components - cardiac death (4.7 vs. 1.5%; logrank p < 0.001) and target vessel revascularization (7.3 vs. 4.7%; logrank p = 0.03) - was higher in high-risk (n = 957) versus low- to intermediate-risk patients (n = 854). Among high-risk patients, treatment with Resolute Integrity (n = 481) and Promus Element stents (n = 476) was similarly safe and efficacious (TVF: 13.3 vs. 13.1%; logrank p = 0.95; definite-or-probable stent thrombosis: 1.7 vs. 1.7%; logrank p = 1.00). CONCLUSIONS The newer-generation Resolute Integrity and Promus Element stents showed similar results in terms of safety and efficacy for treating high-risk patients, who had significantly higher event rates than patients with low-to-intermediate risk.

Abstract
BACKGROUND Dual antiplatelet therapy (DAPT) with aspirin plus a P2Y12 inhibitor prevents ischaemic events after coronary stenting, but increases bleeding. Guidelines support weighting bleeding risk before the selection of treatment duration, but no standardised tool exists for this purpose. METHODS A total of 14 963 patients treated with DAPT after coronary stenting-largely consisting of aspirin and clopidogrel and without indication to oral anticoagulation-were pooled at a single-patient level from eight multicentre randomised clinical trials with independent adjudication of events. Using Cox proportional hazards regression, we identified predictors of out-of-hospital Thrombosis in Myocardial Infarction (TIMI) major or minor bleeding stratified by trial, and developed a numerical bleeding risk score. The predictive performance of the novel score was assessed in the derivation cohort and validated in patients treated with percutaneous coronary intervention from the PLATelet inhibition and patient Outcomes (PLATO) trial (n=8595) and BernPCI registry (n=6172). The novel score was assessed within patients randomised to different DAPT durations (n=10 081) to identify the effect on bleeding and ischaemia of a long (12-24 months) or short (3-6 months) treatment in relation to baseline bleeding risk. FINDINGS The PRECISE-DAPT score (age, creatinine clearance, haemoglobin, white-blood-cell count, and previous spontaneous bleeding) showed a c-index for out-of-hospital TIMI major or minor bleeding of 0·73 (95% CI 0·61-0·85) in the derivation cohort, and 0·70 (0·65-0·74) in the PLATO trial validation cohort and 0·66 (0·61-0·71) in the BernPCI registry validation cohort. A longer DAPT duration significantly increased bleeding in patients at high risk (score ≥25), but not in those with lower risk profiles (pinteraction=0·007), and exerted a significant ischaemic benefit only in this latter group. INTERPRETATION The PRECISE-DAPT score is a simple five-item risk score, which provides a standardised tool for the prediction of out-of-hospital bleeding during DAPT. In the context of a comprehensive clinical evaluation process, this tool can support clinical decision making for treatment duration. FUNDING None.

Abstract
OPINION STATEMENT Percutaneous coronary interventions will never become obsolete, as evolution is inherent to interventional cardiology. Current drug-eluting platforms have appreciably improved their safety and efficacy profiles in different clinical settings compared to first-generation devices such that it is difficult to consider other alternatives. However, there is definite biological plausibility to consider devices with bioabsorbable polymers and/or scaffolds. It is also an undeniable fact that many patients, based on variety of belief systems, would prefer not to have a permanently implanted device. BP DES with or without bioresorbable scaffolds offer advantages over durable polymer DES in restoring normal coronary physiology and vascular adaptive responses, resulting in late lumen gain and plaque regression. They will likely allow flexibility in treating complex CAD. However, so far, we have been able to prove non-inferiority in a selected population of patients without long-term data. Is "as good as" good enough? Are we ready to reach for the BRS or a BP DES in our catheterization laboratory based on preclinical and mechanistic data (endothelialization, OCT imaging, vasomotion) with limited human experience? I am not. While I will maximize my efforts to recruit patients in related randomized controlled trials, the technology is not ready for prime time. Randomized controlled trials are needed to determine whether any or all of these devices improve long-term outcome compared to best in class DP DES. Most definitive evidence is likely about a decade away. Until then, we can learn to be disciplined implanters not only in selecting the appropriate patient but also in perfecting implantation techniques.

Abstract
PURPOSE To compare the 1-year outcomes of a durable polymer Zotarolimus-eluting stent (ZES) versus a biodegradable polymer Biolimus-eluting stent (BES) in patients undergoing percutaneous coronary intervention. MATERIALS AND METHODS A total of 2083 patients from 2 different registries, 1125 treated with BES in NOBORI registry and 858 received ZES in CONSTANT registry were included in this study. Clinical outcomes were compared with the use of propensity score matching (PSM). The primary endpoint was a composite of major adverse cardiovascular and cerebrovascular events (MACCEs) including cardiac death, myocardial infarction, clinically driven target lesion revascularization and stroke. Secondary end points were individual components of MACCEs as well as the incidence of stent thrombosis at 1-year follow-up. RESULTS After PSM, 699 matched pairs of patients (n=1398) showed no significant difference between BES and ZES in the risk of composite MACCEs at 1 year (2.6% vs. 1.7%; p=0.36). Cardiac death was not statistically different between groups (0.7% vs. 0.4%, p=0.73). Target lesion revascularization rate was also similar between BES and ZES (1.1% vs. 0.7%, p=0.579). Non-Q wave myocardial infarction, as well as target-vessel revascularization rate, was similar between the two groups (0.14% for BES and 0.72% for ZES). Both stent types were excellent with no cases of stent thrombosis and rate of Q wave myocardial infarction reported during the follow-up period. CONCLUSION In this cohort of patients treated with BES or ZES, the rate of MACCEs at 1 year was low and significantly not different between both groups.

Abstract
BACKGROUND Drug-eluting stents with biodegradable polymer might be particularly useful in diabetic patients who are at increased risk for target lesion/target vessel revascularization. We therefore aimed at assessing the safety and performance of a biodegradable polymer sirolimus-eluting stent (BP-SES) in combination with comprehensive optimal medical therapy following coronary interventions. METHODS This prospective, multicenter registry was conducted at six centers in Israel. Aside of stent treatment, we aimed for an LDL-C level<70mg/dl; at one and six months post-intervention a diabetic consultancy was required, and follow-up data were collected at six and twelve months. The primary outcome measure was target vessel failure, a composite of cardiac death, target-vessel myocardial infarction and clinically driven target vessel revascularization. Secondary outcomes were target lesion failure, its individual components, and stent thrombosis. RESULTS From August 2013 until May 2014, 120 diabetic patients with 158 lesions were treated with a BP-SES. Mean age was 63.9±9.2years, 27.5% were insulin dependent, 28.3% had a history of myocardial infarction, and 47.5% had prior coronary interventions. By visual estimation, lesions were 3.0±0.5mm in diameter and 15.2±7.4mm long; mean stent diameter and length were 3.0±0.5mm and 19.2±6.8mm. Target vessel failure and target lesion failure at 12months occurred in seven (6.4% [95% CI: 3.1-13.0]) and four patients (3.5% [95% CI: 1.3-9.2]), respectively, and definite stent thrombosis in one patient (1.0% [95% CI: 0.1-7.0]). CONCLUSION Treatment with a BP-SES demonstrated excellent target-vessel and target-lesion revascularization rates in a high-risk diabetic patient population undergoing catheter-based revascularization followed by intensified medical care. ANNOTATED TABLE OF CONTENTS In 120 high-risk diabetic patients with coronary artery stenosis, treatment with the Orsiro sirolimus-eluting stent with biodegradable polymer and comprehensive antidiabetic therapy resulted in excellent clinical outcomes. Target vessel revascularization occurred in 6.4% of patients and target lesion revascularization in 3.5%.

Abstract
Long-term clinical outcomes of new-generation drug-eluting stents in complex anatomic and clinical settings are not well defined. This study assessed the impact of patient and lesion complexity on 2-year outcomes after coronary revascularization with ultrathin strut biodegradable-polymer (BP) sirolimus-eluting stents (SES) versus durable-polymer (DP) everolimus-eluting stents (EES). In a prespecified analysis of the BIOSCIENCE randomized trial (NCT01443104), complex patients (911 of 2,119; 43%) were defined by the presence of acute ST-elevation myocardial infarction (MI); left ventricular ejection fraction ≤30%; renal dysfunction; insulin-treated diabetes; treatment of ostial lesion, bypass graft, unprotected left main lesion; or 3-vessel intervention. The primary end point was target lesion failure (TLF), a composite of cardiac death, target vessel MI, and clinically indicated target lesion revascularization. At 2 years, complex compared with simple patients had a greater risk of TLF (14.5% vs 7.4%, risk ratio 2.05, 95% confidence interval 1.56 to 2.69; p <0.001). The difference was sustained beyond 1 year on landmark analysis. Complex patients had higher rates of the patient-oriented composite end point of death, any MI, or any revascularization (23% vs 14.4%; p <0.001) as well as definite stent thrombosis (1.6% vs 0.4%, p = 0.006). There were no differences in TLF and patient-oriented composite end point between the BP-SES versus DP-EES, consistently among simple and complex patients. In conclusion, patient and lesion complexity had a durable adverse impact on clinical outcomes throughout 2 years of follow-up in this all-comers randomized trial. Safety and efficacy of new-generation BP-SES and DP-EES were comparable, irrespective of complexity status.

Abstract
In the current case series we describe two cases of longitudinal stent deformation in ostial lesions treated with a new generation zotarolimus eluting stent and review current literature on longitudinal stent deformation. Historically not a common occurrence, longitudinal deformation occurred mainly in Promus Element everolimus eluting stents, which had only two rather than the commonly used 3 links between stent rings. Longitudinal deformation commonly occurs secondary to compression of the proximal edge of the stent by either the guide catheters, or intravascular balloons and imaging catheters. The degree of deformation however, depends on the longitudinal strength and design of the stent.

Abstract
BACKGROUND The safety and efficacy of the second-generation biodegradable polymer Cobalt-Chromium sirolimus-eluting stent (EXCEL2) in daily clinical practice remains unknown. Additionally, to meet the China Food and Drug Administration requirements, we conducted an objective performance criterion study from the CREDIT II and CREDIT III trials. METHODS CREDIT II was a randomized trial comparing the EXCEL2 versus EXCEL stent in patients with up to 2 de novo coronary lesions. CREDIT III was a prospective, single-arm study evaluating the efficacy and safety of EXCEL2 in broad types of de novo coronary artery lesions. This pooled analysis included patients in the CREDIT III and EXCEL2 arm of the CREDIT II trial. The primary outcome was 12-month target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction (TV-MI), and clinical indicated target lesion revascularization (CI-TLR). The patient-oriented composite endpoint (PoCE) of all-cause death, all MI, or any revascularization was also analyzed. RESULTS A total of 833 patients were included, consisting of 625 in the CREDIT III trial and 208 in the EXCEL2 arm of the CREDIT II trial. Twelve-month TLF occurred in 6.1% patients, cardiac death in 0.4%, TV-MI in 5%, and CI-TLR in 1.1%. Additionally, 64 (7.7%) PoCE and 3 probable late stent thromboses (0.4%) were recorded. CONCLUSION EXCEL2 stent met the objective performance criterion on efficacy and safety with a low level of 12-month TLF as well as stent thrombosis when treating patients with de novo coronary lesions. © 2017 Wiley Periodicals, Inc.

Abstract
Drug-eluting stents (DES) have been shown to significantly reduce clinical and angiographic restenosis compared to bare metal stents (BMS). The polymer coatings on DES elute antiproliferative drugs to inhibit intimal proliferation and prevent restenosis after stent implantation. Permanent polymers which do not degrade in vivo may increase the likelihood of stent-related delayed arterial healing or polymer hypersensitivity. In turn, these limitations may contribute to an increased risk of late clinical events. Intuitively, a polymer which degrades after completion of drug release, leaving an inert metal scaffold in place, may improve arterial healing by removing a chronic source of inflammation, neoatherosclerosis, and/or late thrombosis. In this way, a biodegradable polymer may reduce late ischemic events. Additionally, improved healing after stent implantation could reduce the requirement for long-term dual antiplatelet therapy and the associated risk of bleeding and cost. This review will focus on bioabsorbable polymer-coated DES currently being evaluated in clinical trials.

Lancet 2016; 388:2607-2617. [PMID: 27806902 DOI: 10.1016/s0140-6736(16)31920-1] [Citation(s) in RCA: 197] [Impact Index Per Article: 24.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2016] [Revised: 10/03/2016] [Accepted: 10/04/2016] [Indexed: 01/07/2023]
Abstract
BACKGROUND In patients with coronary artery disease, treated with durable polymer-coated drug-eluting stents, the life-long presence of the polymer might delay arterial healing. Novel very thin strut biodegradable polymer stents, which leave only a bare metal stent after polymer resorption, might improve long-term outcome. We investigated in allcomers the safety and efficacy of three stents eluting either everolimus, sirolimus, or zotarolimus, often clinically used but never compared, of which the biodegradable polymer everolimus-eluting stent was never before assessed in allcomers. METHODS The large-scale, investigator-initiated, multicentre, assessor and patient blinded, three-arm, randomised, BIO-RESORT non-inferiority trial was done at four clinical sites in the Netherlands. All-comer patients were aged 18 years or older, capable of providing informed consent, and required a percutaneous coronary intervention with drug-eluting stent implantation according to clinical guidelines or the operators' judgment. Exclusion criteria were: participation in another randomised drug or device study before reaching the primary endpoint of that study; planned surgery necessitating interruption of dual antiplatelet therapy within the first 6 months; known intolerance to components of the investigational product or medication required; uncertainty about the adherence to follow-up procedures or an assumed life expectancy of less than 1 year; or known pregnancy. Web-based computer-generated allocation sequences randomly assigned patients (1:1:1) to treatment with very thin strut biodegradable polymer everolimus-eluting or sirolimus-eluting stents (which differ substantially in type, amount, distribution, and resorption speed of their respective coating), or thin strut durable polymer zotarolimus-eluting stents. The primary endpoint was a composite of safety (cardiac death or target vessel-related myocardial infarction) and efficacy (target vessel revascularisation) at 12 months of follow up with a very thin strut biodegradable polymer of either everolimus-eluting or sirolimus-eluting stents, compared with durable polymer zotarolimus-eluting stents, analysed by intention to treat (non-inferiority margin 3·5%). This trial was registered with ClinicalTrials.gov, number NCT01674803. FINDINGS From Dec 21, 2012, to Aug 24, 2015, 3514 patients were enrolled and analysed, of whom 2449 (70%) had acute coronary syndromes, which included 1073 (31%) ST-elevation myocardial infarctions. 12 month follow-up of 3490 (99%) patients (three lost to follow-up; 21 withdrawals) was available. The primary endpoint was met by 55 (5%) of 1172 patients assigned to everolimus-eluting stents, 55 (5%) of 1169 assigned to sirolimus-eluting stents and 63 (5%) of 1173 assigned to zotarolimus-eluting stents. Non-inferiority of the everolimus-eluting stents and sirolimus-eluting stents compared with zotarolimus-eluting stents was confirmed (both -0·7% absolute risk difference, 95% CI -2·4 to 1·1; upper limit of one sided 95% CI 0·8%, pnon-inferiority<0·0001). Definite stent thrombosis (defined by the Academic Research Consortium) occurred in four (0·3%) of 1172 patients who were allocated to everolimus-eluting stents, four (0·3%) of 1169 patients who were allocated to sirolimus-eluting stents, and three (0·3%) of 1173 patients who were allocated to zotarolimus-eluting stents (log-rank p=0·70 for both comparisons with zotarolimus-eluting stents). INTERPRETATION At 12 month follow-up, both very thin strut drug-eluting stents with dissimilar biodegradable polymer coatings (eluting either everolimus or sirolimus) were non-inferior to the durable polymer stent (eluting zotarolimus) in treating allcomers with a high proportion of patients with acute coronary syndromes. The absence of a loss of 1 year safety and efficacy with the use of these two biodegradable polymer-coated stents is a prerequisite before assessing their potential longer-term benefits.

Abstract
AIMS To evaluate the outcomes of patients treated with a new drug-eluting stent formulation with low doses of sirolimus, built in an ultra-thin-strut platform coated with biodegradable abluminal coating. METHODS This study is a randomized trial that tested the main hypothesis that the angiographic late lumen loss of the novel sirolimus-eluting stent is noninferior compared with commercially available biolimus-eluting stent. A final study population comprising 170 patients with one or two de novo lesions was randomized in the ratio 2:1 for sirolimus-eluting stent or biolimus-eluting stent, respectively. The primary endpoint was 9-month angiographic in-stent late lumen loss. Adverse clinical events were prospectively collected for 1 year. RESULTS After 9 months, the novel sirolimus-eluting stent was shown noninferior compared with the biolimus stent for the primary endpoint (angiographic in-stent late lumen loss: 0.20 ± 0.29 mm vs. 0.15 ± 0.20 mm, respectively; P value for noninferiority <0.001). The 1-year incidence of death, myocardial infarction, repeat revascularization, and stent thrombosis remained low and not significantly different between the groups. CONCLUSIONS The present randomized trial demonstrates that the tested novel sirolimus-eluting stent was angiographically noninferior in comparison with a last-generation biolimus-eluting stent.

Abstract
BACKGROUND Diabetes mellitus and angiographic coronary artery disease complexity are intertwined and unfavorably affect prognosis after percutaneous coronary interventions, but their relative impact on long-term outcomes after percutaneous coronary intervention with drug-eluting stents remains controversial. This study determined drug-eluting stents outcomes in relation to diabetic status and coronary artery disease complexity as assessed by the Synergy Between PCI With Taxus and Cardiac Surgery (SYNTAX) score. METHODS AND RESULTS In a patient-level pooled analysis from 4 all-comers trials, 6081 patients were stratified according to diabetic status and according to the median SYNTAX score ≤11 or >11. The primary end point was major adverse cardiac events, a composite of cardiac death, myocardial infarction, and clinically indicated target lesion revascularization within 2 years. Diabetes mellitus was present in 1310 patients (22%), and new-generation drug-eluting stents were used in 4554 patients (75%). Major adverse cardiac events occurred in 173 diabetics (14.5%) and 436 nondiabetic patients (9.9%; P<0.001). In adjusted Cox regression analyses, SYNTAX score and diabetes mellitus were both associated with the primary end point (P<0.001 and P=0.028, respectively; P for interaction, 0.07). In multivariable analyses, diabetic versus nondiabetic patients had higher risks of major adverse cardiac events (hazard ratio, 1.25; 95% confidence interval, 1.03-1.53; P=0.026) and target lesion revascularization (hazard ratio, 1.54; 95% confidence interval, 1.18-2.01; P=0.002) but similar risks of cardiac death (hazard ratio, 1.41; 95% confidence interval, 0.96-2.07; P=0.08) and myocardial infarction (hazard ratio, 0.89; 95% confidence interval, 0.64-1.22; P=0.45), without significant interaction with SYNTAX score ≤11 or >11 for any of the end points. CONCLUSIONS In this population treated with predominantly new-generation drug-eluting stents, diabetic patients were at increased risk for repeat target-lesion revascularization consistently across the spectrum of disease complexity. The SYNTAX score was an independent predictor of 2-year outcomes but did not modify the respective effect of diabetes mellitus. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

Abstract
OBJECTIVES The purpose of this study was to compare the 2-year safety and effectiveness of new- versus early-generation drug-eluting stents (DES) according to the severity of coronary artery disease (CAD) as assessed by the SYNTAX (Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) score. BACKGROUND New-generation DES are considered the standard-of-care in patients with CAD undergoing percutaneous coronary intervention. However, there are few data investigating the effects of new- over early-generation DES according to the anatomic complexity of CAD. METHODS Patient-level data from 4 contemporary, all-comers trials were pooled. The primary device-oriented clinical endpoint was the composite of cardiac death, myocardial infarction, or ischemia-driven target-lesion revascularization (TLR). The principal effectiveness and safety endpoints were TLR and definite stent thrombosis (ST), respectively. Adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated at 2 years for overall comparisons, as well as stratified for patients with lower (SYNTAX score ≤11) and higher complexity (SYNTAX score >11). RESULTS A total of 6,081 patients were included in the study. New-generation DES (n = 4,554) compared with early-generation DES (n = 1,527) reduced the primary endpoint (HR: 0.75 [95% CI: 0.63 to 0.89]; p = 0.001) without interaction (p = 0.219) between patients with lower (HR: 0.86 [95% CI: 0.64 to 1.16]; p = 0.322) versus higher CAD complexity (HR: 0.68 [95% CI: 0.54 to 0.85]; p = 0.001). In patients with SYNTAX score >11, new-generation DES significantly reduced TLR (HR: 0.36 [95% CI: 0.26 to 0.51]; p < 0.001) and definite ST (HR: 0.28 [95% CI: 0.15 to 0.55]; p < 0.001) to a greater extent than in the low-complexity group (TLR pint = 0.059; ST pint = 0.013). New-generation DES decreased the risk of cardiac mortality in patients with SYNTAX score >11 (HR: 0.45 [95% CI: 0.27 to 0.76]; p = 0.003) but not in patients with SYNTAX score ≤11 (pint = 0.042). CONCLUSIONS New-generation DES improve clinical outcomes compared with early-generation DES, with a greater safety and effectiveness in patients with SYNTAX score >11.

Abstract
AIMS We sought to assess the performance of drug-eluting stents combining an ultrathin cobalt-chromium platform with a biodegradable polymer across categories of increasing SYNTAX score (SS). METHODS AND RESULTS Patients included in the BIOSCIENCE trial and randomly allocated to treatment with biodegradable polymer sirolimus-eluting stents (BP-SES) or durable polymer everolimus-eluting stents (DP-EES) were categorised according to SS tertiles (low <8, medium 8-15, high >15). The primary endpoint, target lesion failure (TLF), was defined as a composite of cardiac death, target vessel myocardial infarction and clinically indicated target lesion revascularisation. The patient-oriented endpoint (POCE) included death, myocardial infarction, or any repeat revascularisation. The SS was available in 2,041 out of 2,119 patients (96.3%). At two-year follow-up, patients with an SS >15 experienced higher rates of both TLF and POCE as compared to patients with medium and low SS (14.5% vs. 8.1% and vs. 5.9%, p<0.001; 22.7% vs. 14.9% and vs. 12.4%; p<0.001), respectively. Comparable rates of the composite endpoints were documented for both stent types in each category of SS. CONCLUSIONS Increasing lesion complexity as assessed by SS was associated with higher rates of TLF and POCE in a contemporary PCI population with minimal exclusion criteria. BP-SES and DP-EES showed comparable performance across the entire spectrum of CAD severity.

Abstract
Few data are available on the timing of adverse events in relation to the status of diabetes mellitus and the type of acute coronary syndrome (ACS). We investigated this issue in diabetic and nondiabetic patients admitted with a diagnosis of non-ST-segment elevation ACS (NSTE-ACS) or ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention. Patient-level data from 6 studies (n = 16,601) were pooled and only patients with ACS are included (n = 9,492). Early (0 to 30 days), late (31 to 365 days), and overall (0 to 365 days) events were analyzed. Diabetes mellitus was present in 1,927 patients (20.3%). At 1 year, all-cause mortality was highest for diabetic patients with STEMI (13.4%), followed by diabetic patients with NSTE-ACS (10.3%), nondiabetic patients with STEMI (6.4%) and nondiabetic patients with NSTE-ACS (4.4%; p <0.001). Among patients with diabetes, there was a significant interaction (p <0.001) for STEMI versus NSTE-ACS in early compared with late mortality, due to an excess of early mortality associated with STEMI (9.3% vs 3.7%; hazard ratio 2.31, 95% CI 1.52 to 3.54, p <0.001). Compared with diabetic NSTE-ACS patients, diabetic patients with STEMI had an increased risk of early stent thrombosis (hazard ratio 2.26, 95% CI 1.48 to 3.44, p <0.001), as well as a significant interaction (p = 0.009) in the risk of target lesion revascularization between the early and late follow-up. The distribution of fatal and nonfatal events according to the type of ACS was not influenced by diabetic status. In conclusion, diabetes in ACS setting confers a worse prognosis with 1-year mortality >10% in both STEMI and NSTE-ACS. Notwithstanding the high absolute rates, the temporal distribution of adverse events related to the type of ACS is similar between diabetic and nondiabetic patients.

Abstract
BACKGROUND Recent reports suggest an elevated incidence of bioresorbable vascular scaffold (BVS) thrombosis (scaffold thrombosis [ScT]). OBJECTIVES This study investigated occurrence rates, clinical and angiographic characteristics, and possible mechanisms of ScT in all-comer patients undergoing BVS implantation at 2 German and 2 Swiss hospitals. METHODS A total of 1,305 consecutive patients (mean age 64 years, 78% male) who received 1,870 BVS (mean 1.4 ± 0.8 BVS/patient) were enrolled. Clinical/procedural characteristics, mortality, and ScT data at 485 days (range 312 to 652 days) were examined. RESULTS ScT occurred in 42 patients. The incidence of probable and definite ScT was 1.8% at 30 days and 3.0% at 12 months, without differences among centers (p = 0.60). A total of 22 (52%) ScTs presented as ST-segment elevation myocardial infarction and 6 (17%) as sudden cardiac death. In multivariable analysis, ostial lesions (p = 0.049) and impaired left ventricular ejection fraction (p = 0.019) were independently associated with ScT. Nine (21%) of the ScTs occurred in patients who had suspended dual antiplatelet therapy, in 6 cases prematurely. Lower post-procedural minimum lumen and reference vessel diameters were hallmarks of ScT (all p < 0.0001). The risk of ScT appeared to rapidly increase for post-procedural minimum lumen diameters below 2.4 mm (for the 2.5- to 3.0-mm BVS) and 2.8 mm (for the 3.5-mm BVS). When a BVS-specific implantation strategy was implemented, 12-month ScT rates fell from 3.3% to 1.0%, an effect that remained significant when adjusted for multivariable propensity score (p = 0.012; hazard ratio: 0.19; 95% confidence interval: 0.05 to 0.70). CONCLUSIONS The 12-month incidence of ScT reached 3% and could be significantly reduced when an optimized implantation strategy was employed.

Abstract
Aims Metal absorbable scaffolds constitute a conceptually attractive alternative to polymeric scaffolds. Promising 6-month outcomes of a second-generation drug-eluting absorbable metal scaffold (DREAMS 2G), consisting of an absorbable magnesium scaffold backbone, have been reported. We assessed the 12-month safety and performance of this novel device. Methods and results The prospective, international, multi-centre, first-in-man BIOSOLVE-II trial enrolled 123 patients with up to two de novo lesions with a reference diameter between 2.2 and 3.7 mm. All patients were scheduled for angiographic follow-up at 6 months, and—if subjects consented—at 12 months. Dual antiplatelet therapy was recommended for 6 months. Quantitative coronary angiography (QCA) parameters remained stable from 6 to 12 months [paired data of 42 patients: in-segment late lumen loss 0.20 ± 0.21 mm vs. 0.25 ± 0.22 mm, P = 0.117, Δ 0.05 ± 0.21 mm (95% CI: −0.01;0.12); in-scaffold late lumen loss 0.37 ± 0.25 mm vs. 0.39 ± 0.27 mm, P = 0.446, Δ 0.03 ± 0.22 (95% CI: −0.04;0.10), respectively]. Intravascular ultrasound and optical coherence tomography findings corroborated the QCA results. Target lesion failure occurred in four patients (3.4%), consisting of one death of unknown cause, one target-vessel myocardial infarction, and two clinically driven target lesion revascularization. No additional event occurred beyond the 6-month follow-up. During the entire follow-up of 12 months, none of the patients experienced a definite or probable scaffold thrombosis. Conclusion The novel drug-eluting metal absorbable scaffold DREAMS 2G showed a continuous favourable safety profile up to 12 months and stable angiographic parameters between 6 and 12 months.

Risk and timing of recurrent ischemic events among patients with stable ischemic heart disease, non-ST-segment elevation acute coronary syndrome, and ST-segment elevation myocardial infarction. Am Heart J 2016; 175:56-65. [PMID: 27179724 DOI: 10.1016/j.ahj.2016.01.021] [Citation(s) in RCA: 50] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2015] [Accepted: 01/29/2016] [Indexed: 11/20/2022]
Abstract
BACKGROUND We aimed to compare differences in risk and timing of recurrent ischemic events among patients with stable ischemic heart disease (SIHD), non-ST-segment elevation acute coronary syndrome (NSTE-ACS), and ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). METHODS We performed an individual data pooled analysis of 5 randomized controlled all-comer trials including a total of 8,859 patients and investigated the risk and timing of recurrent ischemic events among patients with SIHD (n = 3,543), NSTE-ACS (n = 3,364), and STEMI (n = 1,952) throughout 2 years of follow-up. RESULTS At 2 years, all-cause mortality was higher among patients with STEMI (6.4%) and NSTE-ACS (6.1%) compared with those with SIHD (4.2%) (STEMI vs SIHD: hazard ratio [HR] 1.40, 95% CI 1.09-1.78, P = .007; NSTE-ACS vs SIHD: 1.40, 95% CI 1.13-1.73, P = .002). In a landmark analysis, the risk of mortality among patients with STEMI compared with those with SIHD was confined to the first 30 days after PCI (HR 6.19, 95% CI 3.15-12.16, P < .001) but was similar between 30 days and 2 years (HR 1.00, 95% CI 0.76-1.33, P = .974) (Pinteraction < .001). Conversely, patients with NSTE-ACS had a higher risk of mortality compared with those with SIHD both within the first 30 days (HR 2.19, 95% CI 1.08-4.47, P = .031) and beyond (HR 1.34, 95% CI 1.07-1.67, P = .012) (Pinteraction < .001). A similar pattern in the differential timing of events was observed for cardiac death. Beyond 30 days, the risk of myocardial infarction was comparable in patients with STEMI and SIHD, whereas the risk in patients with NSTE-ACS was increased (HR 1.65, 95% CI 1.23-2.21, P = .001). CONCLUSION Whereas patients with NSTE-ACS are at increased risk for death at any time after PCI, the mortality of STEMI patients is higher during the first 30 days after PCI but not thereafter compared with patients with SIHD.

Abstract
OBJECTIVES We sought to systematically evaluate the external validity of a contemporary randomized controlled stent trial (BIOSCIENCE). METHODS Baseline characteristics and clinical outcomes of patients enrolled into the BIOSCIENCE trial at Bern University Hospital (n = 1216) were compared to those of patients included in the CARDIOBASE Bern PCI Registry at the same institution (n = 1045). The primary study endpoint was the rate of target lesion failure (TLF), defined as a composite of cardiac death, target vessel-myocardial infarction (MI) or target lesion revascularization (TLR), at 1 year. RESULTS Women were underrepresented in the RCT compared to the registry (25 vs. 29.4 %, p = 0.020). Non-participants were older compared to study participants (69.2 ± 12.4 vs. 67.0 ± 11.6, p < 0.001), and had a higher prevalence of previous cerebrovascular events (10.8 vs. 5.2 %, p < 0.001), and chronic renal failure (35.5 vs. 15.6 %, p < 0.001). ST-segment elevation myocardial infarction (STEMI) and Killip class IV at presentation were more common among non-participants than participants (30.7 vs. 21.1 %, p < 0.001 and 7.8 vs. 0.4 %, p < 0.001, respectively). At 1 year, non-participants experienced a significantly higher rate of TLF, (15.0 vs. 6.5 %, p < 0.001), and patient-oriented composite endpoint (POCE), including death, MI or any repeat revascularization (21.6 vs. 11.2 %, p < 0.001). There was a significant interaction between POCE and presence or absence of an acute coronary syndrome in participants versus non-participants, respectively (p = 0.009). CONCLUSIONS Non-participants of this all-comers trial had a higher risk profile and adverse prognosis compared to study participants. Further efforts are needed to improve the external validity of contemporary RCTs.

Abstract
Objective In the era of bare metal stents (BMSs), alloys have been considered to be better materials for stent design than stainless steel. In the era of biodegradable polymer drug-eluting stents (BP-DESs), the safety and efficacy of BP-DESs with different metal platforms (stainless steel or alloys) have not yet been reported, although their polymers are eventually absorbed, and only the metal platforms remain in the body. This study sought to determine the clinical safety and efficacy of BP-DESs with different platforms compared with other stents (other DESs and BMSs). Methods PubMed, Embase and Clinical Trials.gov were searched for randomized controlled trials (RCTs) that compared BP-DESs with other stents. After performing pooled analysis of BP-DESs and other stents, we performed a subgroup analysis using two classification methods: stent platform and follow-up time. The study characteristics, patient characteristics and clinical outcomes were abstracted. Results Forty RCTs (49 studies) comprising 34,850 patients were included. Biodegradable polymer stainless drug-eluting stents (BP-stainless DESs) were superior to the other stents [mainly stainless drug-eluting stents (DESs)] in terms of pooled definite/probable stent thrombosis (ST) (OR [95% CI] = 0.76[0.61–0.95], p = 0.02), long-term definite/probable ST (OR [95% CI] = 0.73[0.57–0.94], p = 0.01), very late definite/probable ST (OR [95% CI] = 0.56[0.33–0.93], p = 0.03) and long-term definite ST. BP-stainless DESs had lower rates of pooled, mid-term and long-term target vessel revascularization (TVR) and target lesion revascularization (TLR) than the other stainless DESs and BMSs. Furthermore, BP-stainless DESs were associated with lower rates of long-term death than other stainless DESs and lower rates of mid-term myocardial infarction than BMSs. However, only the mid-term and long-term TVR rates were superior in BP-alloy DESs compared with the other stents. Conclusion Our results indirectly suggest that BP-stainless DESs may offer more benefits than BP-alloy DESs in the era of BP-DESs. Further well-designed RCTs comparing BP-stainless with BP-alloy DESs are needed to confirm which platform is better.

Abstract
Background No data are available on the long‐term performance of ultrathin strut biodegradable polymer sirolimus‐eluting stents (BP‐SES). We reported 2‐year clinical outcomes of the BIOSCIENCE (Ultrathin Strut Biodegradable Polymer Sirolimus‐Eluting Stent Versus Durable Polymer Everolimus‐Eluting Stent for Percutaneous Coronary Revascularisation) trial, which compared BP‐SES with durable‐polymer everolimus‐eluting stents (DP‐EES) in patients undergoing percutaneous coronary intervention. Methods and Results A total of 2119 patients with minimal exclusion criteria were assigned to treatment with BP‐SES (n=1063) or DP‐EES (n=1056). Follow‐up at 2 years was available for 2048 patients (97%). The primary end point was target‐lesion failure, a composite of cardiac death, target‐vessel myocardial infarction, or clinically indicated target‐lesion revascularization. At 2 years, target‐lesion failure occurred in 107 patients (10.5%) in the BP‐SES arm and 107 patients (10.4%) in the DP‐EES arm (risk ratio [RR] 1.00, 95% CI 0.77–1.31, P=0.979). There were no significant differences between BP‐SES and DP‐EES with respect to cardiac death (RR 1.01, 95% CI 0.62–1.63, P=0.984), target‐vessel myocardial infarction (RR 0.91, 95% CI 0.60–1.39, P=0.669), target‐lesion revascularization (RR 1.17, 95% CI 0.81–1.71, P=0.403), and definite stent thrombosis (RR 1.38, 95% CI 0.56–3.44, P=0.485). There were 2 cases (0.2%) of definite very late stent thrombosis in the BP‐SES arm and 4 cases (0.4%) in the DP‐EES arm (P=0.423). In the prespecified subgroup of patients with ST‐segment elevation myocardial infarction, BP‐SES was associated with a lower risk of target‐lesion failure compared with DP‐EES (RR 0.48, 95% CI 0.23–0.99, P=0.043, Pinteraction=0.026). Conclusions Comparable safety and efficacy profiles of BP‐SES and DP‐EES were maintained throughout 2 years of follow‐up. Clinical Trial Registration URL: https://www.clinicaltrials.gov.

Biodegradable polymer stents vs second generation drug eluting stents: A meta-analysis and systematic review of randomized controlled trials. World J Cardiol 2016; 8:240-246. [PMID: 26981219 PMCID: PMC4766274 DOI: 10.4330/wjc.v8.i2.240] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2015] [Revised: 09/25/2015] [Accepted: 11/25/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the premise, that biodegradable polymer drug eluting stents (BD-DES) could improve clinical outcomes compared to second generation permanent polymer drug eluting stents (PP-DES), we pooled the data from all the available randomized control trials (RCT) comparing the clinical performance of both these stents.
METHODS: A systematic literature search of PubMed, Cochrane, Google scholar databases, EMBASE, MEDLINE and SCOPUS was performed during time period of January 2001 to April 2015 for RCT and comparing safety and efficacy of BD-DES vs second generation PP-DES. The primary outcomes of interest were definite stent thrombosis, target lesion revascularization, myocardial infarction, cardiac deaths and total deaths during the study period.
RESULTS: A total of 11 RCT’s with a total of 12644 patients were included in the meta-analysis, with 6598 patients in BD-DES vs 6046 patients in second generation PP-DES. The mean follow up period was 16 mo. Pooled analysis showed non-inferiority of BD-DES, comparing events of stent thrombosis (OR = 1.42, 95%CI: 0.79-2.52, P = 0.24), target lesion revascularization (OR = 0.99, 95%CI: 0.84-1.17, P = 0.92), myocardial infarction (OR = 1.06, 95%CI: 0.86-1.29, P = 0.92), cardiac deaths (OR = 1.07, 95%CI 0.82-1.41, P = 0.94) and total deaths (OR = 0.96, 95%CI: 0.80-1.17, P = 0.71).
CONCLUSION: BD-DES, when compared to second generation PP-DES, showed no significant advantage and the outcomes were comparable between both the groups.

Abstract
OBJECTIVES To evaluate, in the FLEX Registry, clinical outcomes of an ultrathin (60 µm) biodegradable polymer-coated Supraflex sirolimus-eluting stent (SES) for the treatment of coronary artery disease. Additionally, to determine the vascular response to the Supraflex SES through optical coherence tomography (OCT) analysis. SETTING Multicentre, single-arm, all-comers, observational registry of patients who were treated with the Supraflex SES, between July 2013 and May 2014, at nine different centres in India. PARTICIPANTS 995 patients (1242 lesions) who were treated with the Supraflex SES, between July 2013 and May 2014, at nine different centres in India. A total of 47 participants underwent OCT analysis at 6 months' follow-up. INTERVENTIONS Percutaneous coronary intervention with Supraflex SES, PRIMARY AND SECONDARY OUTCOME MEASURES: The primary endpoint-the rate of major adverse cardiac events (defined as a composite of cardiac death, myocardial infarction (MI), target lesion revascularisation (TLR))-was analysed during 12 months. RESULTS At 12 months, the primary endpoint occurred in 36 (3.7%) of 980 patients, consisting of 18 (1.8%) cardiac deaths, 16 (1.6%) MI, 7 (0.7%) TLR and 2 (0.2%) cases of non-target lesion target vessel revascularization. In a subset of 47 patients, 1227 cross-sections (9309 struts) were analysed at 6 months by OCT. Overall, a high percentage of struts was covered (98.1%), with a mean neointimal thickness of 0.13 ± 0.06 µm. CONCLUSIONS The FLEX Registry evaluated clinical outcomes in real-world and more complex cohorts and thus provides evidence that the Supraflex SEX can be used safely and routinely in a broader percutaneous coronary intervention population. Also, the Supraflex SES showed high percentage of stent strut coverage and good stent apposition during OCT follow-up.

Abstract
We compared the outcomes of a novel, thin-strut, cobalt-chromium, absorbable, polymer sirolimus-eluting stent (APSES; MiStent) to the durable polymer cobalt-chromium everolimus-eluting stent (EES; Xience). A propensity-matched analysis was performed comparing data from the DES With Sirolimus and a Bioabsorbable Polymer for the Treatment of Patients With De Novo Lesions in the Native Coronary Arteries (DESSOLVE) I and II studies, evaluating the APSES to the EES arm of the Intracoronary Stenting and Angiographic Results: Test Efficacy of 3 Limus-Eluting Stents-4 study. Target lesion failure (TLF) and its components were evaluated at 12 months and annually to 3 years; 805 patients (APSES = 153; EES = 652) were included with propensity matching in 204 patients (APSES = 102; EES = 102). APSES compared with EES had lower TLF at 1 year (3.0% vs 8.0%, p = 0.12) driven by a difference in target lesion revascularization (TLR; 1% vs 6%, p = 0.05), with no difference in target vessel myocardial infarction (p = 0.56) or stent thrombosis (p = 0.31). At 3 years, TLF (5.0% vs 12.5%, p = 0.07) and TLR (2.0% vs 8.4%, p = 0.04) remained lower with APSES. By landmark analysis, there was no significant difference in TLF between 1 and 3 years (p = 0.36). In conclusion, in a propensity-matched analysis, the APSES demonstrated reduced clinically indicated TLR rates at 1 and 3 years compared with the durable polymer EES, with minimal accrual of events between 1 and 3 years.

Abstract
BACKGROUND Although new-generation drug-eluting stents represent the standard of care among patients undergoing percutaneous coronary intervention, there remains debate about differences in efficacy and the risk of stent thrombosis between the Resolute zotarolimus-eluting stent (R-ZES) and the everolimus-eluting stent (EES). The aim of this study was to evaluate the safety and efficacy of the R-ZES compared with EES in patients undergoing percutaneous coronary intervention. METHODS AND RESULTS A systematic literature search of electronic resources was performed using specific search terms until September 2014. Random-effects meta-analysis was performed comparing clinical outcomes between patients treated with R-ZES and EES up to maximum available follow-up. The primary efficacy end point was target-vessel revascularization. The primary safety end point was definite or probable stent thrombosis. Secondary safety end points were cardiac death and target-vessel myocardial infarction. Five trials were identified, including a total of 9899 patients. Compared with EES, R-ZES had similar risks of target-vessel revascularization (risk ratio [RR], 1.06; 95% confidence interval [CI], 0.90-1.24; P=0.50), definite or probable stent thrombosis (RR, 1.26; 95% CI, 0.86-1.85; P=0.24), cardiac death (RR, 1.01; 95% CI, 0.79-1.30; P=0.91), and target-vessel myocardial infarction (RR, 1.10; 95% CI, 0.89-1.36; P=0.39). Moreover, R-ZES and EES had similar risks of late definite or probable very late stent thrombosis (RR, 1.06; 95% CI, 0.53-2.11; P=0.87). No evidence of significant heterogeneity was observed across trials. CONCLUSIONS R-ZES and EES provide similar safety and efficacy among patients undergoing percutaneous coronary intervention.
