Abstract
Abstract
AIMS Patients with acute coronary syndrome (ACS) might represent a specific subgroup, in which bioresorbable scaffold implantation in percutaneous coronary intervention, might lead to better outcomes when compared to conventional treatment. ACS patients (STE-ACS patients in particular) are generally younger, and most often have lesions with softer plaques, a lower plaque burden and less extensive coronary artery disease. In this pre-specified subgroup analysis of the AIDA trial, we evaluated the clinical outcomes of Absorb BVS versus Xience EES treated patients presenting with or without ACS.
Methods and results
This analysis includes the 2-year outcomes of all 1845 patients randomized in the AIDA trial subdivided by clinical presentation, a pre-specified subgroup analysis. We compared patients presenting with ACS with those presenting without ACS (ACS versus no-ACS patients). Patients presenting with ACS were further sub-categorized according to the presence or absence of ST-segment elevation at presentation (STE-ACS versus NSTE-ACS patients). Baseline status by clinical presentation was known in all patients, and 842 (45.6%) patients presented with ACS, 456 (25.2%) with STE-ACS and 377 (20.4%) with NSTE-ACS.The rate of the 2-year primary endpoint of target vessel failure (TVF) was similar after treatment with Absorb BVS or Xience EES in ACS patients (10.2% versus 9.0% respectively; p=0.49) and in no-ACS patients (11.7% versus 10.7% respectively; p=0.67) Definite or probable device thrombosis occurred more frequently with Absorb BVS compared to Xience EES in ACS patients (4.3% versus 1.7% respectively, p=0.03) as well as in no-ACS patients (2.4% versus 0.2% respectively; p=0.002). There were no statistically significant interactions between clinical presentation and randomized device modality for TVF (p=0.80) and for the endpoint of definite or probable device thrombosis (p=0.17).
Conclusions
In ACS patients within AIDA, we found no difference in rates of target vessel failure between the Absorb BVS and Xience EES groups. Rates of definite or definite/probable device thrombosis were higher in the Absorb BVS group throughout all clinical presentations. No significant interaction between ACS and no-ACS patients and the occurrence of TVF

Abstract
Abstract
Aims
Extent of coronary artery disease (CAD) may affect outcomes after percutaneous coronary intervention (PCI). In this pre-specified subgroup analysis of the AIDA trial we evaluated the impact of SXscore on clinical outcomes
Methods and results
AIDA was a multicenter trial comparing Absorb with Xience. SX score was assessed using the baseline diagnostic angiograms. Each coronary lesion with diameter stenosis ≥50% in vessels ≥1.5 mm was scored. All lesion scores were combined to provide the overall SXscore. The angiographic SXscore calculations were performed by core laboratory analysts who were blinded for clinical events (Cardialysis B.V., Rotterdam, The Netherlands). Clinical outcomes were subsequently stratified according to SXscore tertiles: SXlow (SXcore ≤8), SXmid (SXscore >8 and ≤15) and SXhigh (>15). The primary endpoint of this AIDA-trial substudy was target vessel failure (TVF), defined as a composite of cardiac death, target vessel myocardial infarction and target vessel revascularization.
The SXscore was prospectively calculated in 1661 of the 1845 patients (90%). The SXscore ranged from 1 to 57, with a mean±SD of 12.9±8.5 and a median of 11 (Q1-Q3 7–17). In this analysis the SXscore tertiles were defined as SXlow (SXcore ≤8) (n=589), SXmid (SXscore >8 and ≤15) (n=538), and SXhigh (>15) (n=534). Patients in the SXhigh group were older, had a more extensive medical history for previous revascularizations (both PCI and coronary artery bypass grafting), and were more likely to present with a ST-elevation myocardial infarction.
At 2 follow-up the Kaplan-Meier estimates of TVF for the overall AIDA study population was 15.5% in the SXhigh tertile, 10.4% in the SXmid tertile and 4.7% in the SXlow tertile (hazard ratio (HR) 3.53 95% CI 2.28–5.45; P<0.001). The event rate of the primary endpoint of TVF was numerically lower in Absorb when compared to Xience (3.7% versus 5.6%; HR 0.64; 95% CI 0.29 - 1.40; p=0.257) in the SXlow tertile. Patients treated with Absorb and a SXscore >8 had significantly higher event rates as compared to patients with a SXscore ≤8. The rates of TVF in the Absorb BVS population are 15.5% (SXhigh), 11.4% (SXmid), and 3.7% (SXlow), with a significant difference between the SXlow versus SXmid (HR 3.27; 95% CI 1.61–6.68; p=0.001) and SXlow versus SXhigh (HR 4.57; 95% CI 2.29–9.10; p<0.001).
Target Vessel Failure in Absorb BVS
Conclusions
This study demonstrates that implantation of the Absorb in patients with a SXscore ≤8 is associated with numerically lower TVF rates as compared to the Xience drug-eluting stent. The rate of scaffold thrombosis in this SXlow tertile, while still higher for Absorb, is more acceptable than in SXmid and SXhigh score tertiles. Higher SXscore (i.e. >8), both Sxmid and SXhigh, however, appears to be associated with markedly increased risk of device thrombosis, revascularization and myocardial infarction in patients treated with the Absorb.

Abstract
AIMS Percutaneous coronary intervention (PCI) of a bifurcation lesion (BL) is still associated with poorer clinical outcomes when compared with PCI of a non-BL. Therefore, several dedicated coronary bifurcation stents, such as the Tryton Side Branch Stent™ (Tryton Medical, Durham, NC, USA), were developed to improve clinical outcomes. We investigated 6-month clinical outcomes after placement of a Tryton stent in 91 patients treated for 93 BLs in our centre. METHODS AND RESULTS All consecutive patients who have undergone PCI of a BL treated with the Tryton stent in our centre were included. Outcomes were defined as any death, cardiac death, myocardial infarction (MI), any revascularisation, ischaemia-driven target vessel revascularisation (TVR), ischaemia-driven target lesion revascularisation (TLR), stent thrombosis, and target vessel failure (TVF; composite of cardiac death, MI, and ischaemia-driven TVR). Event rates were estimated using the Kaplan-Meier method. Thirty-eight (42 %) patients with acute coronary syndrome (ACS) were included (16 % ST-segment elevation MI (STEMI)). The 6-month event rates were 5.4 % (death), 4.3 % (cardiac death), 2.2 % (MI), 4.5 % (any revascularisation), 4.5 % (TVR), 4.5 % (TLR) and 9.7 % (TVF). CONCLUSION In a real-world all-comers single-centre registry, the use of the Tryton Side Branch Stent was associated with acceptable procedural and promising clinical outcomes at 6 months, including ACS and STEMI patients.

Abstract
It is conceivable that the extent and spatio-temperal expression of dozens or even a few hundred genes are significantly altered during the development and progression of atherosclerosis as compared to normal circumstances. Differential gene expression in vascular cells and in blood cells, due to gene-gene and gene-environment interactions can be considered the molecular basis for this disease. To comprehend the coherence of the complex genetic response to systemic and local atherosclerotic challenges, one needs accessible high through-put technologies to analyze a panel of differentially expressed genes and to describe the interactions between and among their gene products. Fortunately, new technologies have been developed which allow a complete inventory of differential gene expression, i.e. DD/RT-PCR, SAGE and DNA micro-array. The initial data on the application of these technologies in cardiovascular research are now being reported. This review summarizes a number of key observations. Special attention is paid to a few central transcription factors which are differentially expressed in endothelial cells, smooth muscle cells or monocytes/ macrophages. Recent data on the role of nuclear factor-kappaB (NF-kappaB) and peroxisome proliferation-activating receptors (PPARs) are discussed. Like the PPARs, the NGFI-B subfamily of orphan receptors (TR3, MINOR and NOT) also belongs to the steroid/thryroid hormone receptor superfamily of transcription factors. We report that this subfamily is specifically induced in a sub-population of neointimal smooth muscle cells. Furthermore, intriguing new data implicating the Sp/XKLF family of transcription factors in cell-cell communication and maintenance of the atherogenic phenotype are mentioned. A member of the Sp/XKLF family, the shear stress-regulated lung Krüppel-like factor (LKLF) is speculated to be instrumental for the communication between endothelial cells and smooth muscle cells. Taken together, the expectation is that the fundamental knowledge obtained on atherogenesis and the data that will be acquired during the coming decade with the new, powerful high through-put methodologies will lead to novel modalities to treat patients suffering from cardiovascular disease. In view of the phenotypic changes of vascular and blood-borne cells during atherogenesis, therapeutic interventions likely will focus on reversal of an acquired phenotype by gene therapy approach or by using specific drugs which interfere with aberrant gene expression.
