Abstract
BACKGROUND This review concerns the putative benefit of percutaneous coronary intervention (PCI) over optimal medical therapy (OMT) for symptomatic patients with stable angina pectoris, or for asymptomatic persons in whom screening tests have revealed coronary heart disease (CHD; this entity has been newly designated chronic coronary syndrome, or CCS). Moreover, it addresses the question whether the indications for which PCI is now performed in Germany on patients with CCS are consistent with current scientific knowledge. METHODS The pathophysiological concept of CHD and ischemia induction is discussed in the light of the scientific literature. This concept implies that PCI might be beneficial in the treatment of CCS. The benefit of PCI over OMT has now been evaluated in seven randomized trials (the so-called milestone trials). The current situation in Germany is presented here as well, on the basis of the available data. RESULTS The pathophysiological concept of CHD implies that the particular coronary artery stenoses that are likely to give rise to a myocardial infarction (the so-called vulnerable plaques) cannot be identified prospectively with current methods. Moreover, a coronary artery stenosis will not necessarily cause myocardial ischemia. All of the randomized trials carried out to date that have compared OMT to PCI-plus-OMT in patients with CCS have led to the conclusion that PCI, because it focuses on individual coronary artery stenoses, cannot prolong survival or lower the incidence of myocardial infarction over the long term. This remains the case even if a single coronary artery stenosis is known to be causing moderate or severe myocardial ischemia (a conclusion of the ISCHEMIA trial). A PCI performed only because the coronary stenosis or stenoses meet certain morphological criteria, without any demonstration of a resulting functional disturbance, is generally detrimental to the health of the patient, with rare exceptions, and is inconsistent with the recommendations of current guidelines. The number of PCIs being performed in Germany at present is high compared to other countries; this arouses concern that the indications for it may be dubious in many cases. CONCLUSION Current data imply that PCI for CCS does not improve outcomes in a large percentage of cases. A symptomatic benefit exists only in patients with frequent angina pectoris. The selection of CCS patients for PCI needs to be more strictly bound to the recommendations of current guidelines, particularly in Germany.

Abstract
In the early 1990s, the idea of Transcatheter Aortic Valve Implantation (TAVI) emerged from clinicians by the insight that the long-term hemodynamic and clinical results of aortic balloon valvuloplasty to treat aortic stenonosis were not satisfying. Thus, Anderson and Cribier developed the balloon-expandable and Figulla and Laborde the self-expendable TAVI systems. Sceptical views by the surgical colleagues and the industry delayed the rapid development of this disruptive new therapy until 2002, when Alain Cribier demonstrated for the first time the proof of his concept. Bulky devices and paravalvular leakages in patients treated in terms of compassionate care resulted in high mortality rates. From 2005 onwards, the treatment of patients not at highest risk using smoother devices in clinical trials could demonstrate that the technology was equivalent to surgical aortic valve replacement. The transapical access route initiated the heart team approach with the surgical colleagues, however, this access route is presently expiring due to its greater trauma. The need to treat also aortic regurgitation is addressed by the "clipping technology" of JenaValve™. Ongoing clinical trials investigate an extended indication for TAVI at an earlier stage of aortic stenosis, or in reduced ejection fraction, and just demonstrated the safety and efficiency even in low surgical risk patients.

Abstract
AIMS Evaluation of aortic stenosis (AS) is based on echocardiographic measurement of mean pressure gradient (MPG), flow velocity (Vmax) and aortic valve area (AVA). The objective of the present study was to analyse the impact of systemic haemodynamic variables and concomitant mitral regurgitation (MR) on aortic MPG, Vmax and AVA in severe AS. METHODS AND RESULTS A pulsatile circulatory model was designed to study function and interdependence of stenotic aortic (AVA: 1.0 cm², 0.8 cm² and 0.6 cm²) and insufficient mitral prosthetic valves (n=8; effective regurgitant orifice area [EROA] <0.2 cm² vs. >0.4 cm²) using Doppler ultrasound. In the absence of severe MR, a stepwise increase of stroke volume (SV) and a decrease of AVA was associated with a proportional increase of aortic MPG. When MR with EROA <0.2 cm² vs. >0.4 cm² was introduced, forward SV decreased significantly (70.9±1.1 ml vs. 60.8±1.6 ml vs. 47.4±1.1 ml; p=0.02) while MR volume increased proportionally. This was associated with a subsequent reduction of aortic MPG (57.1±9.4 mmHg vs. 48.6±13.8 mmHg vs. 33.64±9.5 mmHg; p=0.035) and Vmax (5.09±0.4 m/s vs. 4.91±0.73 m/s vs. 3.75±0.57 m/s; p=0.007). Calculated AVA remained unchanged (without MR: AVA=0.53±0.04 cm² vs. with MR: AVA=0.52±0.05 cm²; p=ns). In the setting of severe AS without MR, changes of vascular resistance (SVR) and compliance (C) did not impact on aortic MPG (low SVR and C: 66±13.8 mmHg and 61.1±20 mmHg vs. high SVR and C: 60.9±9.2 mmHg and 71.5±13.5 mmHg; p=ns) In concomitant severe MR, aortic MPG and Vmax were not significantly reduced by increased SVR (36.6±2.2 mmHg vs. 34.9±5.6 mmHg, p=0.608; 3.89±0.18 m/s vs. 3.96±0.28 m/s; p=ns). CONCLUSIONS Systemic haemodynamic variables and concomitant MR may potentially affect diagnostic accuracy of echocardiographic AS evaluation. As demonstrated in the present study, MPG and Vmax are flow-dependent and significantly reduced by a reduction of forward SV from concomitant severe MR, resulting in another entity of low-flow low-gradient aortic stenosis. In contrast, calculated AVA appears to be a robust parameter of AS evaluation if severe MR is present. Changes of SVR and C did not affect the diagnostic accuracy of AS evaluation.

Abstract
Recently, transcatheter therapy has expanded the treatment options for patients with heart valve disease. With the growing understanding of tricuspid regurgitation and its natural history, it becomes increasingly obvious that this patient population is a heterogeneous cohort presenting for treatment in different stages of a continuous disease process. It is still unclear which interventional approach will result in functional and clinical success and in which subtype of patient population. This article reviews the pathophysiologic background and current evidence for caval valve implantation and examines the potential role of this approach for the treatment of severe tricuspid regurgitation.

Abstract
Background Endothelial progenitor cells (EPC) are involved in neovascularization and endothelial integrity. They might be protective in atherosclerosis. Optical coherence tomography (OCT) is a precise intracoronary imaging modality that allows assessment of subintimal plaque development. We evaluated the influence of EPC on coronary plaque burden in stable disease and implemented a novel computational plaque analysis algorithm using OCT. Methods Forty-three patients (69.8% males, 69.6 ± 7.7 years) were investigated by OCT during re-angiography 6 months after elective stent implantation. Different subpopulations of EPCs were identified by flow cytometry according to their co-expression of antigens (CD34+, CD133+, kinase domain receptor, KDR+). An algorithm was applied to calculate the underlying total plaque burden of the stented segments from OCT images. Plaque morphology was assessed according to international consensus in OCT imaging. Results A cumulative sub-strut plaque volume of 10.87 ± 12.7 mm3 and a sub-stent plaque area of 16.23 ± 17.0 mm2 were found within the stented vessel segments with no significant differences between different stent types. All EPC subpopulations (mean of EPC levels: CD34+/CD133+: 2.66 ± 2.0%; CD34+/KDR+: 7.50 ± 5.0%; CD34+/CD133+/KDR+: 1.12 ± 1.0%) inversely correlated with the identified underlying total plaque volume and plaque area (p ≤ 0.012). Conclusions This novel analysis algorithm allows for the first time comprehensive quantification of coronary plaque burden by OCT and illustration as spread out vessel charts. Increased EPC levels are associated with less sub-stent coronary plaque burden which adds to previous findings of their protective role in atherosclerosis.

Abstract
UNLABELLED Systemic sclerosis (SSc) is a systemic, autoimmune connective tissue disease characterized by vasculopathy and microvascular changes. Fluorescence Optical Imaging (FOI) is a technique used to assess inflammation in patients with arthritis; in this study FOI is used to quantify inflammation in the hand. Endothelial Microparticle (EMP) can reflect damage or activation of the endothelium but also actively modulate processes of inflammation, coagulation and vascular function. The aim of the present study was to quantify EMP and FOI, to determine an association between these microparticles and inflammation and to endothelial function. METHODS EMP were quantified in plasma samples of 25 patients (24 female, 1 male, age: 41 ± 9 years) with SSc using flow cytometry. EMP was defined as CD31+/CD42- MP, and CD62+ MP. Perivascular inflammation was assessed using fluorescence optical imaging (FOI) of the hand. Macrovascular endothelial function was non-invasively estimated using the Endopat system. RESULTS Plasma levels of CD31+/CD42- EMP and CD62+ EMP were lower in patients with SSc compared to controls (both p < 0.05). An impaired endothelial function with an increased hyperemia index was observed. A strong association could be demonstrated between CD62+ EMP and perivascular soft tissue inflammation as assessed by the FOI global score (Spearman, p = 0.002, r = 0.61). CONCLUSIONS EMP indicate molecular vascular damage in SSc; in this study a strong association between EMP and perivascular inflammation as quantified by FOI is demonstrated. Consequently EMP, using FOI, may be a potential marker benefitting the diagnosis and therapy monitoring of patients with SSc with associated Raynaud's phenomenon.

Abstract
Background Percutaneous coronary interventions (PCI) with drug-coated balloons (DCB) might be a promising trade-off between balloon angioplasty and drug-eluting stents, since DCB inhibit neointimal proliferation and limit duration of dual antiplatelet therapy. We investigated the safety, feasibility, and 6-month results of fractional flow reserve (FFR)-guided use of the paclitaxel-coated SeQuent Please® balloon without stenting for elective PCI of de novo lesions. Methods and results In 46 patients (54 lesions) with stable symptomatic coronary artery disease (CAD), a FFR-guided POBA (plain old balloon angioplasty) was performed. In case of a sufficient POBA result with residual stenosis < 40 %, FFR > 0.8 and no severe dissection, the target lesion was finally dilated using the DCB. Quantitative coronary angiography (QCA) was performed before and after the index procedure and at 6-month follow-up (f/u) to calculate late lumen loss (LLL) and net luminal gain (NLG). Optical coherence tomography (OCT) was performed at f/u to assess vascular remodeling. DCB-only treatment was applied to 43 patients (51 lesions), while 3 patients (3 lesions) needed provisional stenting. Invasive f/u was completed in 39 patients (47 lesions). At the stenotic site, the lumen diameter showed a trend toward progressive increase at f/u (LLL: −0.13 ± 0.44 mm, n.s.; NLG: 1.10 ± 0.53 mm, p < 0.001) without aneurysm formation or restenosis after DCB-only treatment. Conclusions FFR-guided DCB-only PCI of de novo lesions appeared feasible and safe in stable CAD with clopidogrel discontinuation after 4 weeks, showing a trend toward positive vessel remodeling without lumen loss at 6 months.

Abstract
Aim of this study was the assessment of left atrial appendage (LAA) dimensions comparing 2D- to 3D-TEE measurements in patients with nonvalvular atrial fibrillation undergoing percutaneous LAA occlusion. Patients underwent transesophageal echocardiography (TEE) before, during and 45 days after intervention. The maximal LAA orifice diameters in 2D-TEE (LODmax 2D) were obtained from multiple views. Test-retest reliability (screening vs. implantation), inter- and intra-observer variability for echocardiographic parameters were assessed by two independent examiners. Overall, 74 patients underwent percutaneous LAA occlusion. 2D-TEE significantly underestimated the maximal LAA orifice diameter compared with 3D-TEE (screening LODmax 2D 21.11 ± 2.75 mm vs. 22.52 ± 3.45 mm for LODmax 3D, p < 0.001; during implantation LODmax 2D 21.56 ± 3.48 mm vs. 22.99 ± 3.24 mm for LODmax 3D, p < 0.001). The intraobserver and interobserver variability calculated as coefficient of variation (CV) were both lower for the 3D-TEE quantification of the maximal orifice diameter (intraobserver CV for 3D-TEE 6.07 % vs. 9.31 % for 2D-TEE; interobserver CV for 3D-TEE 6.73 % vs. 9.69 % for 2D-TEE). Compared to 3D-TEE the test-retest reliability of 2D-TEE showed a lower intraclass correlation coefficient calculated as average of raters (0.92 for 3D-TEE vs. for 2D-TEE 0.78). Firstly, 2D-TEE significantly underestimates the maximal LAA orifice diameter compared to 3D-TEE. Secondly, 3D-TEE measurements are associated with a lower observer variability and higher reliability than 2D-TEE.

Abstract
The transcatheter valve technology pipeline has started as simple balloon valvuloplasty for the treatment of stenotic heart valves and evolved since the year 2000 to either repair or replace heart valves percutaneously with multiple devices. In this review, the present technology and its application are illuminated and a glimpse into the near future is dared from a physician's perspective.

Abstract
BACKGROUND An a priori combined therapy of a bare metal stent post-dilated with a paclitaxel- -coated balloon (PCB) was investigated with optical coherence tomography (OCT) at 2 and 6 months regarding vessel response. Previous studies have shown inconsistent results and the time course of vessel healing after such an interventional strategy is unknown. METHODS Thirty-three de novo lesions in 32 patients were electively treated. Six-month OCT analysis was available in 24 lesions. Two-month OCT follow-up was obtained in 16 lesions. Sequential OCT at 2 and 6 months was available in 7 patients. A novel 3-dimensional picture of vessel segments as spread outs was implemented. RESULTS Severe incomplete stent apposition (ISA) accompanied by significantly lower strut coverage were found at 2-month compared with 6-month follow-up (ISA struts: 11.4 ± 11.8% vs. 1.8 ± 4.8%, p = 0.001; uncovered struts: 14.5 ± 14.8% vs. 2.0 ± 5.3%, p = 0.001). ISA size diminished over time and the possibly observed phenomenon of positive vessel remodeling (remodeling volume: 4.9 ± 5.9 mm3 at 2-months vs. 2.0 ± 2.6 mm3 at 6-months; p = 0.042) was largely reversible in most lesions. CONCLUSIONS Bare metal stenting with adjunctive application of paclitaxel by a coated bal-loon shows transient severe incomplete strut apposition, most likely due to focal positive ves-sel remodeling. Thus, caution is needed in bailout situations following a PCB angioplasty. A novel illustration of OCT parameters as "carpet views" enables a comprehensive analysis of investigated stents.

Abstract
New pharmacological approaches are introduced for the treatment of chronic right heart failure which aim at reduced mortality. Riociguat is a new drug for the treatment of chronic thrombembolic pulmonary hypertension. Transcatheter valve interventions are established for treatment of pulmonary valve diseases and introduced as promising upcoming therapeutic options for tricuspid regurgitation. The management of acute right heart failure is supported by the miniaturization of mechanical circulatory support systems with percutaneous cannulation applicable in terms of "Bridge to Recovery" and "Bridge to Decision" concepts and effective long-term support, respectively.

Abstract
BACKGROUND During exposure to high altitude, the immune system is altered. During hypoxia, an increase in interleukin (IL)-6 and high sensitivity C-reactive protein (hs-CRP), and an increase in natural killer cells and decrease in T cells in blood was shown. However, the impact of hypoxia on dendritic cells has not been investigated yet. MATERIAL AND METHODS Twelve healthy volunteers were subjected to a transient normobaric hypoxia for 6·5 h simulating an oxygen concentration at 5500 m. During exposure to hypoxia, blood samples were collected and analysed by flow cytometrical cell sorting (FACS) for circulating myeloid (mDCs) and plasmacytoid (pDCs) DCs. Serum levels of IL-6 and tumour necrosis factor (TNF)-α were analysed. In a cell culture hypoxia chamber, blood samples were subjected to the same hypoxia and analysed regarding DCs. RESULTS Exposure to normobaric hypoxia induced a significant decrease in circulating pDCs about 45% (P = 0·001) but not of mDC compared to baseline normoxia. Furthermore, we observed a significant increase of TNF-α about 340% (P = 0·03) and of IL-6 about 286% (P = 0·002). In cell culture experiments exposure of blood to hypoxia led to no significant changes in DCs, so that a direct cytotoxic effect was excluded. During hypoxia, we observed a transient increase in stromal-derived factor 1 (SDF-1) which is important for pDC tissue recruitment. CONCLUSIONS We show a significant decrease in circulating pDCs during hypoxia in parallel to a pro-inflammatory response. Further studies are necessary to evaluate whether the decrease in circulating pDCs might be the result of an enhanced tissue recruitment.

Abstract
Fetal variants of tenascin-C are not expressed in healthy adult myocardium. But, there is a relevant re-occurrence during pathologic cardiac tissue and vascular remodeling. Thus, these molecules, in particular B and C domain containing tenascin-C, might qualify as promising novel biomarkers for diagnosis and prognosis estimation. Since a stable extracellular deposition of fetal tenascin-C variants is present in diseased cardiac tissue, the molecules are excellent target structures for antibody-based delivery of diagnostic (e.g., radionuclides) or therapeutic (bioactive payloads) agents directly to the site of disease. Against the background that fetal tenascin-C variants are functionally involved in cardiovascular tissue remodeling, therapeutic functional blocking strategies could be experimentally tested in the future.

Abstract
One of the main limitations of percutaneous coronary interventions is the restenosis, occurring in small-diameter arteries, and efforts are high to find improved intracoronary devices to prevent in-stent-restenosis. Aim of this study was to produce a new in vitro test platform for restenosis research, suitable for long-term cell proliferation and migration studies in stented vessels. Fresh segments of porcine coronary arteries were obtained for decellularization and were then reseeded with human coronary artery endothelial (HCAEC) and human coronary artery smooth muscle cells (HCASMC). Subsequently, bare metal stents (BMS) and drug eluting stents (DES), respectively, were implanted and the segments were reseeded with HCAEC and HCASMC for up to three months. The stented segments were examined at time zero and after 2, 4, 6, 8 and 12 weeks by histochemical and immunohistochemical characterization and the reseeded areas before and after stent implantation were measured. We have found that cells formed multiple layers after three months, and the detection with both CD31 and a-smooth muscle actin specific antibodies showed that HCAEC and HCASMC are adherent and growing in several layers. Furthermore, we could show a significantly smaller proliferation area in DES (70% ± 3.5%), compared to BMS (17% ± 2.3%). These data are similar to animal and human studies. Therefore, this vessel model might appear as an initial benchmark for testing new anti-proliferative endovascular therapies and consequently helps to reduce animal experiments in this research area.

Abstract
BACKGROUND AND AIMS Management of chronic rejection is challenging since there are not sufficient preventive or therapeutic strategies. The rejection process leads to overexpression of ED-A(+) fibronectin (ED-A(+) Fn). The human antibody F8, specific to ED-A(+) Fn, may serve as a vehicle for targeted delivery of bioactive payloads, e.g. interleukin 10 (IL-10). The aim of this study was to investigate the therapeutic effects of the fusion protein F8-interleukin-10 (F8-IL10) in the process of chronic rejection development. METHODS A heterotopic rat heart transplantation model was used to induce chronic rejection. For therapeutic interventions, the immunocytokines F8-humanIL10 (DEKAVIL), F8-ratIL10 as well as KSF-humanIL10 (irrelevant antigen-specificity) were used. Treatment was performed weekly for 10 weeks starting at day 7 after transplantation (1mg/animal). RESULTS In the cardiac allografts, treatment with F8-huIL10 or F8-ratIL10 was associated with increased heart weights, a higher grade of chronic rejection, increased CIF, higher protein expression levels of alpha-smooth muscle actin (α-SMA), an augmented infiltration with inflammatory cells (CD4+, CD8+ and CD68+ cells) and higher serum levels of brain natriuretic peptide (BNP) compared to the control groups. CONCLUSIONS All observed treatment effects are transplantation-specific since the F8 antibody is specific to ED-A(+) Fn that is not expressed in healthy hearts. A clear targeting effect of F8-huIL10 as well as F8-ratIL10 could be proven. Against that background, a further study is needed to address the question, if F8-IL10 treatment is capable to reduce CAV and CIF starting at a time point when chronic rejection has fully developed (therapeutic approach).

Abstract
Transcatheter procedures have been adopted as novel treatment strategy for patients with valvular heart disease, particularly for those who are inoperable or at high risk for surgical valve procedures. Significant technological advances have resulted in an improvement of devices for transcatheter aortic valve replacement (TAVI) with downsizing of crossing profiles, reduction in the rate of paravalvular leakage and conduction abnormalities as well as a lower short- and mid-term mortality and a higher patient acceptance. In the near future, TAVI may potentially develop as first-line treatment for the majority of patients with aortic valve disease. For patients with mitral and pulmonary stenosis, balloon valvuloplasty is effective and well established and should be preferred over valve replacement, last but not least also for economic reasons. For treatment of mitral regurgitation, several transcatheter devices aiming to restore or replace mitral valve function are currently under investigation. This review summarizes the current state of interventional treatment of valvular heart disease along with implications for the future.

Abstract
Recently it could be demonstrated that systolic and diastolic blood pressure variability (BPV) as well as segmented Poincare plot analysis (SPPA) contribute to risk stratification in patients suffering from dilated cardiomyopathy (DCM). The aim of this study was to improve the risk stratification applying a multivariate technique including QT variability (QTV). We enrolled and significantly separated 56 low risk and 13 high risk DCM patients by nearly all applied BPV and QTV methods, but not with traditional heart rate variability analysis. The optimum set of two indices calculating the multivariate discriminate analysis (DA) included one BPV index calculated by symbolic dynamics method (DBP(Shannon)) and one index calculated from QTV (QTV(log)) achieving an area under the receiver operating characteristics curve (AUC) of 92%, sensitivity of 92.3% and specificity of 89.3%. Performing only electrocardiogram analysis, the optimum multivariate approach including indices from segmented Poincaré plot analysis and QTV still achieved a remarkable AUC of 88.3%. Increasing the number of indices for multivariate DA up to three, we achieved an AUC of 95.7%, sensitivity of 100% and specificity of 85.7% including one clinical, one BPV and one QTV index. Summarizing, we identified DCM patients with an increased risk of sudden cardiac death applying QTV analysis in a multivariate approach.

Abstract
BACKGROUND Endothelial progenitor cells (EPCs) and cytokines seem to play a pivotal role in arterial healing after stent implantation. Using optical coherence tomography (OCT) as a high-resolution imaging technique, we aimed to assess the influence of circulating EPCs and levels of Il-1 cytokines on stent coverage and in-stent proliferation. METHODS Eighty-nine patients were randomly treated with either Xience V drug-eluting stent (DES; n = 48) or bare-metal stent (BMS) postdilated with the SeQuent Please drug-eluting balloon (DEB; n = 41). EPC populations (CD34+/CD133+ and CD34+/CD133+/KDR+ EPC) and cytokines (Il-1ra, Il-18, and Il-1α) were measured before percutaneous coronary intervention using flow cytometry or immunoassay. Vessel remodeling was analyzed using coronary angiography and OCT at 6-month follow-up. RESULTS Indexed neointimal volume and maximal proliferation thickness correlated inversely with EPC levels in the entire study population (r = -0.220; P=.04 and r = -0.253; P=.02) and the BMS + DEB subgroup (r = -0.344; P=.03 and r = -0.374; P=.02). Late lumen loss (LLL) was associated with the proatherogenic Il-18 concentration in the main population (r = 0.342; P=.01) and the BMS + DEB group (r = 0.471; P=.01). In the DES subgroup, associations with proliferation and LLL were lacking. Associations for stent strut coverage were not observed. CONCLUSIONS A high EPC count seems to be a favorable individual patient factor, since it was associated with less instent proliferation. Contrarily, high Il-18 levels lead to more LLL, which emphasizes its proatherogenic properties.

Abstract
BACKGROUND In this randomized trial, strut coverage and neointimal proliferation of a therapy of bare metal stents (BMSs) postdilated with the paclitaxel drug-eluting balloon (DEB) was compared with everolimus drug-eluting stents (DESs) at 6-month follow-up using optical coherence tomography. We hypothesized sufficient stent coverage at follow-up. METHODS AND RESULTS A total of 105 lesions in 90 patients were treated with either XIENCE V DES (n=51) or BMS postdilated with the SeQuent Please DEB (n=54). At follow-up, comparable results on the primary optical coherence tomography end point (percentage uncovered struts 5.64±9.65% in BMS+DEB versus 4.93±9.29% in DES; P=0.366) were found. Thus, BMS+DEB achieved the prespecified noninferiority margin of 5% uncovered struts versus DES (difference between treatment means, 0.71%; one-sided upper 95% confidence interval, 4.14%; noninferiority P=0.04). Optical coherence tomography analysis showed significantly more global neointimal proliferation in the BMS+DEB group (15.7±7.8 versus 11.0±5.2 mm(3) proliferation volume/cm stent length; P=0.002). No significant focal in-stent stenosis analyzed with angiography (percentage diameter stenosis at follow-up, 22.8±11.9 versus 16.9±10.4; P=0.014) and optical coherence tomography (peak local area stenosis, 39.5±13.8% versus 36.8±15.6%; P=0.409) was found. CONCLUSIONS Good stent strut coverage of >94% was found in both therapy groups. Despite greater suppression of global neointimal growth in DES, both DES and BMS+DEB effectively prevented clinically relevant focal restenosis at 6-month follow-up.

Abstract
OBJECTIVES The postcardiac arrest syndrome occurs after global hypoxia leading to microcirculatory impairment. Nitric oxide (NO) is a key molecule regulating microvascular function. The enzyme arginase has been suggested to modulate microvascular function by regulating NO metabolism. Therefore, we investigated whether arginase increases following global hypoxia and resuscitation and tested whether arginase inhibition influences altered microcirculation in resuscitated patients. METHODS To determine the effect of global hypoxia on circulating arginase levels, fourteen healthy subjects were exposed to hypoxia in a normobaric hypoxia chamber (FiO² = 9·9%). In addition, 31 resuscitated patients were characterized clinically, and arginase 1 was measured on days 1 and 3. In eight resuscitated patients, a microcirculatory analysis was performed using a sidestream darkfield microcirculation camera. Perfused capillary density (PCD) was recorded before and after sublingual incubation of N-omega-hydroxy-nor-l-arginine (nor-NOHA) alone or together with the NOS inhibitor NG-monomethyl-l-arginine (l-NMMA). RESULTS Circulating arginase 1 levels increased in healthy volunteers following global hypoxia in the hypoxic chamber (P < 0·01). In addition, arginase 1 levels were higher on day 1 (69·1 ± 83·3 ng/mL) and on day 3 (44·2 ± 65·6 ng/mL) after resuscitation than in control subjects (P < 0·001). Incubation of the sublingual mucosa with nor-NOHA increased microcirculatory perfusion (P < 0·001). This effect was inhibited by co-incubation with K-NMMA. CONCLUSIONS Circulating arginase 1 levels are increased following exposure to global hypoxia and in patients who have been successfully resuscitated after cardiac arrest. Topical arginase inhibition improves microcirculatory perfusion following resuscitation. This is of potential therapeutic importance for the postcardiac arrest syndrome.

Abstract
OBJECTIVES Obesity during adolescence is an increasing health problem in industrial countries. The co-morbidities associated with obesity include important metabolic diseases. METHODS To analyze the effect of a weight-loss program, we recruited 12 obese, male adolescents before entering this program. We determined body weight measures at baseline, 6-week and 36-month follow-up. Also, the long-term changes of blood pressure, HbA1c, and CRP were evaluated. Twenty healthy age-matched adolescents served as controls. RESULTS Within the intervention group ((body mass index [BMI, kg/m2] > 95th percentile for age and sex, age 13-17 years) the BMI and BMI-standard deviation score [SDS] were significantly reduced in the 6-week follow-up after completing the weight loss program. However, the significant weight-reduction effect was not persistent until the 36-month follow-up. CONCLUSION The 6-week weight-loss program had beneficial short-term effects on body weight, BMI, and BMI-SDS in obese adolescents, but these effects could not be maintained until the 36-month follow-up.
