- Abstract
Background Inhospital stent thrombosis (ST) and cerebrovascular accidents (CVA) are rare but serious adverse events after percutaneous coronary intervention (PCI). The association of ST or CVA with long-term outcome after PCI remains poorly investigated. Methods The study included 18,334 consecutive patients who underwent PCI. Patients were divided into 3 groups: the group with ST, the group with CVA, and the group without these events. The primary outcome was all-cause mortality at 3-year follow-up. Results Inhospital ST or CVA occurred in 59 patients (0.32%) and in 90 patients (0. 49%), respectively. There were 2,149 deaths (11.7%) during the follow-up: 26 deaths among patients with ST, 32 deaths among patients with CVA, and 2,091 deaths among patients without ST or CVA (Kaplan-Meier estimates of 3-year mortality 45.3%, 38.0%, and 12.9%, odds ratio 6.1, 95% CI 3.6-10.2, P < .001 for ST group vs the group without ST or CVA and odds ratio 4.2 [2.7-6.6], P < .001 for CVA group vs the group without ST or CVA). There was no significant difference in the 3-year mortality between CVA and ST groups ( P = .29). The Cox proportional hazards model showed that ST (adjusted hazard ratio 4.97, 95% CI 2.58-9.56, P < .001) and CVA (adjusted hazard ratio 2.25 [1.25-4.04], P = .006) were independently associated with the increased risk of 3-year mortality. Conclusion Inhospital ST and CVA after PCI are associated with the increased risk of 3-year mortality. Both events seem to have a similar impact on long-term survival. [ABSTRACT FROM AUTHOR]

The efficacy and safety of ticagrelor versus prasugrel according to smoking status in patients with acute coronary syndromes (ACS) are not known. We assessed the efficacy and safety of ticagrelor versus prasugrel according to smoking status in patients with ACS undergoing invasive management. This pre-specified analysis of the ISAR-REACT 5 trial included 1349 smokers and 2652 nonsmokers randomized to receive ticagrelor or prasugrel. The primary endpoint was the incidence of death, myocardial infarction, or stroke; the secondary endpoint was the incidence of Bleeding Academic Research Consortium (BARC) type 3 to 5 bleeding (both endpoints assessed at 12 months). There was no significant treatment arm-by-smoking status interaction regarding the efficacy outcome. The primary endpoint occurred in 47 patients (7.0%) in the ticagrelor group and 41 patients (6.2%) in the prasugrel group in smokers (hazard ratio [HR] = 1.15; 95% confidence interval [CI] 0.76–1.75; P = 0.510) and in 133 patients (10.2%) in the ticagrelor group and 94 patients (7.2%) in the prasugrel group in nonsmokers (HR = 1.44 [1.10–1.87]; P = 0.007; P for interaction = 0.378). The secondary endpoint occurred in 27 patients (4.6%) in the ticagrelor group and 33 patients (5.6%) in the prasugrel group in smokers (HR = 0.81 [0.49–1.35]; P = 0.412) and in 66 patients (6.0%) in the ticagrelor group and 46 patients (4.4%) in the prasugrel group in nonsmokers (HR = 1.38 [0.94–2.01]; P = 0.097). In patients with ACS undergoing an invasive management strategy, the smoking status did not significantly interact with the relative treatment effect of ticagrelor vs. prasugrel. NCT01944800 • In ACS patients, ticagrelor and prasugrel showed similar efficacy regardless of smoking status. • Bleeding risk was comparable between ticagrelor and prasugrel in smokers and nonsmokers. • Smoking status does not interfere with the relative treatment effect of ticagrelor vs. prasugrel.

BLOOD platelet aggregation , *PLATELET count , *THROMBOEMBOLISM , *BLOOD platelets , *DIAGNOSIS - Abstract
The extent of the involvement of platelets in venous thromboembolisms (VTE) is still not fully understood. Immature platelets are large, RNA-rich, prothrombotic platelets. They are involved in arterial thromboembolisms and are associated with adverse cardiovascular events. Their role in VTE has not been investigated before. The aim of this study was to assess different platelet parameters including immature platelet fraction (IPF), immature platelet count (IPC), absolute platelet count and platelet aggregation (PA) over time in patients with VTE at time of diagnosis, as well as at 3–10 days and at 90–110 days after diagnosis. 50 healthy volunteers similar in age and sex to patients served as controls at diagnosis. IPF was measured by the Sysmex XE-5000 analyzer, PA was assessed using the Multiplate analyzer. Diagnosis of VTE had no relevant effect on IPF and IPC whereas absolute platelet count and PA were significantly decreased compared to controls. In the course of VTE, IPF decreased significantly, whereas IPC, absolute platelet count and PA increased. In conclusion, VTE was associated with relevant changes of the absolute platelet count and PA at diagnosis, as well as changes in IPF and IPC over time reflecting a relevant and measurable platelet consumption in VTEs.

Background: Since the outbreak of the COVID-19 pandemic, a number of risk factors for a poor outcome have been identified. Thereby, cardiovascular comorbidity has a major impact on mortality. We investigated whether coronary calcification as a marker for coronary artery disease (CAD) is appropriate for risk prediction in COVID-19. Methods: Hospitalized patients with COVID-19 (n = 109) were analyzed regarding clinical outcome after native computed tomography (CT) imaging for COVID-19 screening. CAC (coronary calcium score) and clinical outcome (need for intensive care treatment or death) data were calculated following a standardized protocol. We defined three endpoints: critical COVID-19 and transfer to ICU, fatal COVID-19 and death, composite endpoint critical and fatal COVID-19, a composite of ICU treatment and death. We evaluated the association of clinical outcome with the CAC. Patients were dichotomized by the median of CAC. Hazard ratios and odds ratios were calculated for the events death or ICU or a composite of death and ICU. Results: We observed significantly more events for patients with CAC above the group's median of 31 for critical outcome (HR: 1.97[1.09,3.57], p = 0.026), for fatal outcome (HR: 4.95[1.07,22.9], p = 0.041) and the composite endpoint (HR: 2.31[1.28,4.17], p = 0.0056. Also, odds ratio was significantly increased for critical outcome (OR: 3.01 [1.37, 6.61], p = 0.01) and for fatal outcome (OR: 5.3 [1.09, 25.8], p = 0.02). Conclusion: The results indicate a significant association between CAC and clinical outcome in COVID-19. Our data therefore suggest that CAC might be useful in risk prediction in patients with COVID-19. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate myocardial viability assessment with hybrid 2-deoxy-2-[18F]fluoro-d-glucose positron emission tomography/magnetic resonance imaging ([18F]FDG-PET/MR) in predicting left ventricular (LV) wall motion recovery after percutaneous revascularisation of coronary chronic total occlusion (CTO). Methods and results: Forty-nine patients with CTO and corresponding wall motion abnormality (WMA) underwent [18F]FDG-PET/MR imaging for viability assessment prior to percutaneous revascularisation. After 3–6 months, 23 patients underwent follow-up MR to evaluate wall motion recovery. In total, 124 segments were assigned to the CTO territories, while 80 segments displayed impaired wall motion. Of these, 68% (54) were concordantly viable in PET and MR; conversely, only 2 segments (2%) were assessed non-viable by both modalities. However, 30% showed a discordant viability pattern, either PET non-viable/MR viable (3 segments, 4%) or PET viable/MR non-viable (21 segments, 26%), and the latter revealed a significant wall motion improvement at follow-up (p = 0.033). Combined imaging by [18F]FDG-PET/MR showed a fair accuracy in predicting myocardial recovery after CTO revascularisation (PET/MR area under ROC curve (AUC) = 0.72, p = 0.002), which was superior to LGE-MR (AUC = 0.66) and [18F]FDG-PET (AUC = 0.58) alone. Conclusion: Hybrid PET/MR imaging prior to CTO revascularisation predicts more accurately the recovery of dysfunctional myocardium than PET or MR alone. Its complementary information may identify regions of viable myocardium with increased potential for functional recovery. [ABSTRACT FROM AUTHOR]

Background: Outcome data after extended long-term follow-up of patients with coronary artery disease treated with drug-eluting stents (DES) in randomized clinical trials are scant.Objectives: Performance differences among devices may be expected to emerge over time depending on whether stenting is done with polymer-free or durable polymer DES. This study assessed the 10-year outcomes of patients enrolled in the ISAR-TEST-5 (Test Efficacy of Sirolimus- and Probucol-Eluting Versus Zotarolimus-Eluting Stents) trial.Methods: A total of 3,002 patients were randomized to treatment with either polymer-free sirolimus- and probucol-eluting stents (n = 2,002) or durable polymer zotarolimus-eluting stents (n = 1,000). The primary endpoint was the composite of cardiac death, target vessel-related myocardial infarction, or target lesion revascularization (a device-oriented composite endpoint [DOCE]). Additional endpoints of interest were the patient-oriented composite endpoint (POCE), including all-cause death, any myocardial infarction, or any revascularization; individual components of the composite endpoints; and definite or probable stent thrombosis.Results: The median age of the patients at randomization was 67.8 years. At 10 years, 63.9% of patients were alive. The rates of DOCE and POCE were high in both groups with no difference in the incidence between polymer-free sirolimus- and probucol-eluting stents and durable polymer zotarolimus-eluting stents (DOCE: 43.8% vs. 43.0%, respectively; hazard ratio: 1.01; 95% confidence interval [CI]: 0.89 to 1.14; p = 0.90; POCE: 66.2% vs. 67.7%, respectively; hazard ratio: 0.94; 95% CI: 0.86 to 1.04; p = 0.22). The rates of the individual components of the composite endpoints were comparable in both groups. The incidence of definite/probable stent thrombosis over 10 years was low and comparable in both groups (1.6% vs. 1.9%; hazard ratio: 0.85; 95% CI: 0.46 to 1.54; p = 0.58).Conclusions: At 10 years, there were no measurable differences in outcomes between patients treated with polymer-free versus durable polymer DES. The incidence of stent thrombosis was low and comparable in both groups. High overall adverse clinical event rates were observed during extended follow-up.

MYOCARDIAL infarction , *PRASUGREL , *INFLAMMATION , *HEALING , *MYOCARDIUM - Abstract
The local inflammatory response following acute myocardial infarction (AMI) is increasingly being recognized as a central factor determining infarct healing. Myocardial inflammation can be visualized in patients using fasting 18F-FDG PET/MRI. Although this novel biosignal correlates with long-term functional outcome, the corresponding cellular substrate is not well understood. Here we present a retrospective analysis of 29 patients with AMI who underwent revascularization, suggesting a connection between post infarction myocardial fasting 18F-FDG uptake, monocyte platelet aggregates (MPA), and P2Y 12 inhibition. In detail, patients with high MPA percentages of CD14highCD16+ and CD14lowCD16+ monocytes had significantly higher local 18F-FDG uptake (SUV mean) in the infarcted myocardium than patients with low MPA (p < 0.05). Furthermore, there was an association of high MPA percentage in all monocyte subpopulations with deteriorating ΔLV-EF after 6 months (p < 0.01), which was confirmed in an extended analysis with additional 29 patients without PET/MRI data available. In this analysis, administration of Ticagrelor was associated with lower MPA percentage of CD14high monocyte subpopulations than Clopidogrel (p < 0.01) or Prasugrel (p < 0.05). Taken together, the findings from this analysis suggest that platelet aggregability may affect monocyte extravasation into the infarcted myocardium and influence long-term functional outcome. P2Y 12 inhibition may intervene in this pathophysiologic process. Prospective studies are needed to further examine this important relationship. • High relative levels of monocyte-platelet aggregates are associated with strong myocardial inflammation in patients with AMI. • P2Y12 inhibitor choice may affect MPA formation, with ticagrelor showing the lowest relative MPA levels. • The relationship between platelet inhibition, myocardial inflammation, and cardiac remodeling may represent an axis of therapeutic relevance.

Background: In the ISAR-CABG (Is Drug-Eluting-Stenting Associated with Improved Results in Coronary Artery Bypass Grafts?) trial, clinical outcomes at 1 year in patients undergoing treatment of saphenous vein graft lesions were superior with drug-eluting stents (DES) versus bare-metal stents.Objectives: The authors compared outcomes between treatment groups at 5 years.Methods: Patients were randomized (1:1:1:3) to receive DES (either permanent-polymer paclitaxel-eluting stents, permanent-polymer sirolimus-eluting stents, or biodegradable-polymer sirolimus-eluting stents) or bare-metal stents. The primary endpoint was the combined incidence of death, myocardial infarction (MI), or target lesion revascularization (TLR). Secondary endpoints were the composite of death or MI and TLR.Results: A total of 610 patients were allocated to treatment with DES (n = 303) or bare-metal stents (n = 307). At 5 years, the primary endpoint occurred in 159 (55.5%) versus 157 (53.6%) patients in the DES and bare-metal stent groups, respectively (hazard ratio [HR]: 0.98; 95% confidence interval [CI]: 0.79 to 1.23; p = 0.89). There was interaction between treatment effect and time (pinteraction = 0.005), with a lower event rate in the DES group at 1 year (HR: 0.64; 95% CI: 0.44 to 0.94; p = 0.02) but a numerically higher rate between 1 and 5 years (HR: 1.24; 95% CI: 0.94 to 1.63; p = 0.13). Death or MI occurred in 93 (32.8%) versus 108 (36.6%) patients, respectively (HR: 0.85; 95% CI: 0.64 to 1.12; p = 0.24), without significant interaction between treatment effect and time (pinteraction = 0.57). TLR occurred in 84 (33.1%) versus 69 (25.5%) patients in the DES and bare-metal stent groups, respectively (HR: 1.20; 95% CI: 0.87 to 1.64; p = 0.27). There was interaction between treatment effect and time (pinteraction <0.001): TLR was significantly lower in the DES group at 1 year (HR: 0.49; 95% CI: 0.28 to 0.86; p = 0.01) but significantly higher thereafter (HR: 2.02; 95% CI: 1.32 to 3.08; p = 0.001).Conclusions: In patients undergoing treatment of saphenous vein graft lesions, the advantage of DES over bare-metal stents demonstrated at 1 year was lost at 5 years due to higher attrition of efficacy in the DES group.

Background The incidence of pulmonary vein stenosis (PVS) as complication after pulmonary vein isolation (PVI) for atrial fibrillation (AF) has decreased in the last decade. However, as PVI for AF is becoming more prevalent, the incidence remains considerable in absolute terms. The purpose of this meta-analysis is to investigate the optimal approach for management of PVS after PVI for AF. Methods and results We searched electronic scientific databases for studies comparing plain balloon angioplasty (BA) versus stenting for PVS after PVI for AF. Aggregate data were pooled to perform a meta-analysis. The primary and secondary outcomes were restenosis requiring repeated intervention and procedure-related complications, respectively. A total of 4 studies, treating 315 PVS in 188 patients (BA, n = 171 versus stent, n = 144 PVS) were considered. After a median follow-up of 32 months, the overall incidence of restenosis was 46%. A percutaneous therapy with BA was associated with a higher risk for restenosis requiring repeat intervention compared to stent (risk ratio — RR, 95% confidence interval [95% CI] = 2.18 [1.64–2.89], p < 0.001). Procedure-related complications were comparable between BA and stent (RR [95% CI] = 0.96 [0.19–4.96], p = 0.96). The time to diagnosis of PVS after PVI for AF did not modify the treatment effect for the primary outcome with BA versus stent ( p for interaction = 0.16). Conclusions In patients presenting PVS after PVI for AF, a percutaneous therapy with BA is associated with higher risk for restenosis requiring repeat intervention as compared to stent. These percutaneous therapies display comparable safety. [ABSTRACT FROM AUTHOR]

Background Angioplasty with paclitaxel-coated balloons (PCB) is recommended for treatment of patients with coronary in-stent restenosis (ISR) according to European clinical practice guidelines. Most clinical trials have investigated iopromide-based PCB and there is a paucity of data comparing efficacy against butyryl-tri-hexyl citrate (BTHC)-based PCB. Our aim was to compare the performance of two widely-used PCB in the treatment of coronary ISR. Methods We analysed patients treated with BTHC- or iopromide-PCB for treatment of drug-eluting stent ISR in the setting of 2 consecutive trials with identical inclusion and exclusion criteria. The primary endpoint was diameter stenosis at 6–8 month angiographic surveillance. The secondary endpoint of interest was the composite of death, myocardial infarction (MI) or target-lesion revascularisation (TLR) at 1 year. Multivariate analysis was performed to adjust for differences in baseline characteristics between groups. Results In total, 264 patients were treated with BTHC-PCB ( n = 127) or iopromide-PCB ( n = 137). Baseline patient characteristics were similar for both groups. Post-procedure stenosis was slightly larger with BTHC-PCB (22.3 [SD 8.2]% vs. 18.4 [SD 9.9]%, P = 0.001). At 6–8 month angiography, diameter stenosis was 40.4 [SD 21.9]% vs. 37.4 [SD 21.4]% in the BTHC-PCB and iopromide-PCB groups, respectively ( P = 0.16, P adjusted = 0.32). At 1 year, death, MI or TLR occurred in 29 (23.2%) vs. 32 (23.4%) patients in the BTHC-PCB and iopromide-PCB groups, respectively (HR 1.03 [95% CI 0.62–1.70], P = 0.91, P adjusted = 0.96). Conclusions In patients undergoing intervention for ISR, angioplasty with BTHC-PCB showed similar angiographic and clinical results at 1 year compared with iopromide-PCB. [ABSTRACT FROM AUTHOR]

Weltweit leben etwa zwölf Millionen Patienten mit einem angeborenen Herzfehler. Diese sind sowohl mit Folgeerscheinung nach Interventionen/Operationen als auch mit Alterserscheinungen konfrontiert. Arrhythmien, Thromboembolien und Schlaganfälle sind Probleme, die einer Blutverdünnung bedürfen. In dieser retrospektiven monozentrischen klinischen Studie wurden 215 Patienten hingehend der Verträglichkeit einer Therapie mit DOAK untersucht. Es konnte gezeigt werden, dass die Therapie sicher ist. Worldwide, about 12 million patients have congenital heart disease. They face aftereffects of interventional or operational treatment as well as acquired comorbidities. Arrhythmias, thromboembolic events, and strokes are problems that require anticoagulation. 215 patients under a therapy with DOACs were retrospectively identified. Treatment was safe in ACHD patients.

Die Ablation bei paroxysmalem Vorhofflimmern ist Therapiestandard. Trotz Ablation kommt es zu Rezidiven der Arrhythmie. Ziel der Dissertation ist es, den Erfolg der Ablation bei Patienten mit oder ohne pathologischen Apnoe-Hypopnoe-Index (AHI) zu vergleichen. Der AHI wurde mit einem einfachen Screening-Gerät ermittelt. In den Untersuchungen nach 3 Monaten zeigt sich ein signifikanter Zusammenhang zwischen einem AHI (>15/h) und einem Rezidiv, nach 12 Monaten ein schwach signifikanter Zusammenhang. Der AHI (>15/h) erwies sich als unabhängiger Prädiktor für ein Rezidiv. Ablation in paroxysmal atrial fibrillation is standard therapy. Despite the ablation, the arrhythmia recurs. The aim of the dissertation is to compare the success of ablation in patients with or without a pathological apnea-hypopnea index (AHI). The AHI was determined with a simple screening device. The studies after 3 months showed a significant connection between an AHI (> 15 / h) and a recurrence, after 12 months a weakly significant connection. The AHI (> 15 / h) proved to be an independent predictor of recurrence.

This retrospective, longitudinal study aimed to investigate the effectiveness of the main treatment options in terms of changes in functional health in adolescents and adults with congenital heart disease (CHD). Generally, active treatment was associated with better health-related quality of life (HRQoL) over time. Patients reported better physical HRQoL after surgery and catheter intervention, although this effect was not detectable in the objectively measured exercise capacity. Hence, parallel assessment of HRQoL and exercise capacity is essential in the evaluation of adolescents and adults with CHD. Das Ziel dieser retrospektiven, longitudinalen Studie war es, die Effektivität der wichtigsten Therapieoptionen bezüglich Veränderungen von funktionalen Gesundheitsvariablen in Jugendlichen und Erwachsenen mit angeborenen Herzfehlern (AHF) zu untersuchen. Im Allgemeinen war eine aktive Therapie mit besserer gesundheitsbezogener Lebensqualität verbunden. Patienten gaben eine bessere physische Lebensqualität nach einer Operation und Herzkatheterintervention an, obwohl dieser Effekt nicht in einer Verbesserung der Leistungsfähigkeit nachweisbar war. Daher ist die parallele Erfassung von Lebensqualität und Leistungsfähigkeit für die Evaluation von Jugendlichen und Erwachsenen mit AHF erforderlich.

Medizin und Gesundheit ,ddc:610 - Abstract
Die Studie beleuchtet Langzeittherapieeffekte einer „single dose“ RTX-Therapie zur Remissionsinduktion/ Erhaltungstherapie bei AAV (GPA, MPA). Eine Limitation ist der gesteigerte Einsatz supportiver Immunsuppression, sodass die Therapie für die Praxis als tendenziell unterlegen eingestuft wird. Da das „single dose“-Regime imstande ist, selbst bei Patient*innen mit höchstem Rezidivrisikoprofil eine Aktivitätskontrolle zu erreichen, erscheint der individualisierte Einsatz allerdings gerechtfertigt. The study sheds light on possible long-term therapeutic effects of a “single dose” RTX therapy for remission induction and maintenance therapy in AAV (GPA, MPA). One limitation is the increased use of supportive immunosuppression, so that the therapy tends to be classified as inferior in practice. But the “single dose” regime is able to achieve activity control even in patients with the highest risk of relapse, so that its individualized use appears justified

Myokardschäden nach nicht-herzchirurgischen Operationen, definiert durch den postoperativen Anstieg von hoch-sensitivem Troponin T (hsTnT), sind mit kardiovaskulären Komplikationen und erhöhter Mortalität assoziiert. Bei 1010 Hochrisikopatienten werden zwei unterschiedliche Verläufe des hsTnT auf ihren prognostischen Wert für kardiale und nicht-kardiale Komplikationen nach elektiven nicht-herzchirurgischen Operationen untersucht. Diese wurden definiert anhand der Clavien-Dindo Klassifikation in den neun Domänen des Postoperative Morbidity Survey. Myocardial injury after non-cardiac surgery, defined by a postoperative elevation of high-sensitive Troponin T (hsTnT), is associated with cardiovascular events and mortality. The aim of this study was to investigate in 1010 high risk patients, if different cut-offs and courses of hsTnT can differentiate the risk of cardiac or non-cardiac complications after elective non-cardiac surgery. They were defined by a Clavien-Dindo classification in the nine domains of the Postoperative Morbidity Survey.

Der Myokardinfarkt löst eine komplexe Entzündungsreaktion mit zahlreichen Variablen und Mechanismen aus, die vereinfachend in zwei Phasen abläuft. Hierbei scheint eine optimale Balance der beiden Phasen entscheidend für eine gute Heilung zu sein. Mittels Positronen-Emissions-Tomographie (18F-FDG-PET) ist eine prognostische Aussage und auf dieser Basis eine Risikostratifizierung möglich, die in Zukunft eine zielgerichtete Therapie wie etwa mit immunmodulatorischen Medikamenten ermöglichen kann. Myocardial infarction initiates a complex inflammatory response being influenced by several mechanisms and variables, that can be divided roughly into two phases, whereby these two phases should be balanced ideally to enable appropriate healing after myocardial infarction. Positron emission tomography (18F-FDG-PET) allows prognostic prediction and thus risk stratification as a basis for therapeutic interventions in future. Possible therapeutic approaches are for example immunomodulatory drugs.

The purpose of this investigation was to systematically evaluate the spatial distribution of image quality improvement with dual-source radiofrequency (RF) transmission in cardiac steady-state free precession sequences at 3.0 T. Imaging with and without dual-source RF transmission was performed in 30 patients. Contrast-to-noise ratio for the left ventricular myocardium was significantly higher using dual-source RF transmission, but improvement was not uniformly distributed. The posterior myocardium showed significantly less contrast-to-noise ratio gain than all other cardiac regions. Signal-to-noise ratio increase was higher in the right than in the left ventricle. Subjective image quality was significantly enhanced by parallel RF transmission. [ABSTRACT FROM AUTHOR]

This study evaluated the performance of hybrid fluorodeoxyglucose positron emission tomography/magnetic resonance (FDG PET/MR) imaging in myocardial viability assessment in patients with chronic total occlusions (CTO) of coronary arteries, and in the prediction of regional wall motion recovery after revascularisation of CTO lesions, in comparison to PET and MR alone. FDG PET/MR imaging showed a fair accuracy in predicting wall motion improvement after CTO revascularisation, being superior to MR and PET alone. Bei Patienten mit chronischen totalen Verschlüssen der Koronararterien, erlaubt die kombinierte FDG PET/MRT Bildgebung eine bessere Straatifizierung hinsichtlich einer linksventrikulären Funktionsverbesserung nach Revaskularisation im Vergleich zu PET oder MRT allein. Die durch die beiden Modalitäten zusätzlich erbrachten Informationen können dabei helfen kleine Areale von vitalem Myokard zu identifizieren, die nach einer Revaskularisation die Kontraktilität steigern können.

Objectives: This study sought to compare the safety and efficacy of the zotarolimus-eluting stent (ZES) and the everolimus-eluting stent (EES) for treatment of unprotected left main coronary artery (uLMCA) disease. Background: The second-generation ZES and EES have reduced the risk of restenosis in large patient cohorts. However, their comparative performance in uLMCA lesions is not known. Methods: In this study, patients with symptomatic coronary artery disease undergoing percutaneous coronary intervention for uLMCA lesions were randomly assigned to receive either a ZES (n = 324) or an EES (n = 326). The primary endpoint was the combined incidence of death, myocardial infarction, and target lesion revascularization at 1 year. Secondary endpoints were definite or probable stent thrombosis at 1 year and angiographic restenosis based on analysis of the left main coronary artery area at follow-up angiography. Results: At 1 year, the cumulative incidence of the primary endpoint was 17.5% in the ZES group and 14.3% in the EES group (relative risk: 1.26; 95% confidence interval [CI]: 0.85 to 1.85; p = 0.25). Three patients in the ZES group (0.9%) and 2 patients in the EES group (0.6%) experienced definite or probable stent thrombosis (p > 0.99). All-cause mortality at 1 year was equal in the 2 groups (5.6%; relative risk: 1.00; 95% CI: 0.52 to 1.93; p = 0.98). Angiographic restenosis occurred in 21.5% of patients in the ZES group and 16.8% in the EES group (relative risk: 1.28; 95% CI: 0.86 to 1.92; p = 0.24). Conclusions: Within the statistical limitations of the present study, treatment of uLMCA lesions with a ZES or an EES provided comparable clinical and angiographic outcomes at 1-year follow-up.

Bei der transkraniellen Dopplersonographie und der retinalen Gefäßanalyse handelt es sich um zwei neue, vielversprechende Diagnoseinstrumente der Alzheimer-Erkrankung. Um ihr Potential zu evaluieren, wurden gesunde Kontrollprobanden (HC), Alzheimer-Patienten im Stadium der Demenz (ADD) sowie Patienten mit leichter kognitiver Einschränkung (MCI) und Subgruppen (MCI-nonAD, MCI-AD) untersucht. Bei ADD und MCI zeigten sich erhöhte Werte für PI und RI sowie eine vergrößerte und verzögerte retinale arterioläre Gefäßreaktion. Im Vergleich zu etablierten Biomarkern sind beide Methoden einfach durchzuführen, nicht-invasiv und flächendeckend verfügbar sowie kostengünstig. The transcranial Doppler ultrasound (TCD) and the retinal vessel analysis are two new and promising methods to diagnose Alzheimer’s Disease. Evaluating their potential for diagnosis, healthy controls (HC), Alzheimer patients suffering from dementia (ADD) and patients with mild cognitive impairment (MCI) as well as subgroups (MCI-nonAD, MCI-AD) were examined. We measured increased results for PI and RI and an increased and delayed retinal arterial vessel response for ADD and MCI. In comparison to established biomarkers, these methods are easy-to-administer, non-invasive, affordable and widely available.

In dieser Studie wurde retrospektiv der Effekt von kontinuierlich verabreichtem Marcumar im Vergleich zu kontinuierlich verabreichten NOAKs (Apixaban, Dabigatran und Rivaroxaban) auf die peripher vaskuläre Komplikationsrate bezüglich Pseudoaneurysmen, Ateriovenöse Fisteln und Blutungen untersucht. Die kontinuierliche Therapie mit NOAKs scheint mindestens gleich sicher zu sein wie die Therapie mit Marcumar. Bei Dabigatran traten sogar signifikant weniger Major Blutungen auf (p = 0,01). Retrospectively the effect of continuously administered Marcumar compared to continuously administered NOACs (Apixaban, Dabigatran and Rivaroxaban) on the peripheral vascular complication rates for pseudoaneurysms, ateriovenous fistulas and bleeding after radiofrequency ablation was investigated in this study. Uninterrupted therapy with NOACs appears to be at least as safe as uninterrupted therapy with Marcumar. In the group of Dabigatran there was significantly less major bleeding (p=0,01).

Kidney transplanted patients frequently suffer high blood pressure values. These high values are major risk factors to graft failure and cardiovascular morbidity. These risks should be averted by renal denervation – a catheter based ablation procedure. This technique intends to interrupt conduction pathways of the central nervous system, which are responsible for elevated blood pressure values. Subject of the randomized study was to examine the feasibility and efficacy of renal sympathetic denervation compared to only medication therapy. After 6 months, we determined a significant reduction in office blood pressure and a decrease in nighttime values in 24h blood pressure recordings. Erhöhte Blutdruckwerte sind ein häufiges Problem für nierentansplantierte Patienten. Aufgrund dieser erhöhten Werte besteht ein bedeutendes Risiko für ein vorzeitiges Transplantatversagen und kardiovaskuläre Morbidität. Bei der Therapie mittels renaler Denervation handelt es sich um ein kathetergestützes Ablationsverfahren. Ziel dieser Methode ist die Durchtrennung von Leitungsbahnen, welche zu einer Fehlregulation des Blutdrucks führen können. Gegenstand der randomisierten Studie war die Untersuchung der Durchführbarkeit und Wirksamkeit dieses Verfahrens, verglichen mit einer alleinigen medikamentösen Therapie. Nach 6 Monaten zeigten sich eine signifikante Reduktion der Office Blutdruckwerte und ein Rückgang der nächtlichen Werte in der 24h Blutdruckmessung.

Ambulante Herzsportgruppentherapie ist ein in Deutschland seit Jahrzehnten etabliertes Konzept zur langfristigen Sicherung des kardialen Rehabilitationserfolges. Die Datenlage hinsichtlich der tatsächlichen Effektivität derartiger Gruppen im Langzeitverlauf ist dagegen äußerst gering. Ziel dieser Arbeit war es daher, langjährige Herzgruppenteilnehmer hinsichtlich der Entwicklung der körperlichen Belastbarkeit und des kardiovaskulären Risikoprofils zu untersuchen. For decades, outpatient heart group therapy has been a well-established concept for long-term maintenance of cardiac rehabilitation outcomes in Germany. In contrast, data on the effectiveness of such groups is extremely scarce. The aim of this thesis was to evaluate the long-term effects of participation in heart groups on exercise capacity and cardiovascular risk profile in a large cohort of cardiac patientis.

In der monozentrischen Studie wurde die endovaskuläre Therapie einer symptomatischen extrakraniellen Vertebralisstenose mit Drug-eluting Stents (DES) und Bare-metal Stents (BMS) untersucht. Analysiert wurden alle Eingriffe am Klinikum RdI und DHZM zwischen 1997 - 2012. Zudem wurde der Einsatz beider Stent-Typen durch eine Metaanalyse bereits veröffentlichter Studien verglichen. Das Verfahren stellt eine sichere und effektive Therapieoption dar. Der Gebrauch von ballondilatierbaren und v. a. DES ist den selbstexpandierbaren Stents überlegen. Der Einsatz von DES ist im Gegensatz zu BMS mit einer signifikant niedrigeren Rate an Restenosen und erneuten Symptomen verbunden. This single-center study investigates the endovascular therapy of an extracranial vertebral artery stenosis with drug-eluting stents (DES) and bare-metal stents (BMS). All procedures at the Klinikum RdI and the DHZM between 1997 – 2012 were analysed. Furthermore the use of both stent types was compared by meta-analysis of already published studies. The procedure is safe and effective. The use of balloon-expandable stents and especially DES is superior to self-expandable stents. The application of DES significantly reduces the rate of restenosis and recurrence of symptoms compared to BMS.

Die Prädiktoren der Stentthrombose waren: Diabetes mellitus, akuter ST-Hebungs-Myokardinfarkt, komplexe Morphologie der behandelten Läsionen, In-Stent-Restenose und eine verbleibende Stenose nach der Stentimplantation. Im Vergleich zu Bare-metal Stents zeigten Drug-eluting Stents der 1. Generation ein erhöhtes Risiko der Stentthrombose, was nicht der Fall war bei Drug-eluting Stents der 2. Generation. Stent thrombosis is a severe complication of coronary stent implantation. The aim of this study was to determine the incidence and predictors of stent thrombosis. The incidence of stent thrombosis among 18 334 patients was 1.3%. Diabetes mellitus, clinical presentation with ST segment elevation myocardial infarction, complex lesion morphology, in-stent restenosis and residual stenosis after stent implantation were predictive factors for stent thrombosis. In comparison with bare metal stents the risk of stent thrombosis was significantly increased with first generation drug eluting stents, which was not the case with second generation drug eluting stents.

Der Faktor melanoma inhibitory activity 3 (MIA3) steht im Zusammenhang mit der Tumorsuppression und der Atherosklerose. Genomweite Studien haben auf eine mögliche Relevanz einzelner Variationen im MIA3-Gen für Krankheiten der Koronararterien hingewiesen. Diese Arbeit leistete einen wesentlich Beitrag zu einer systematischen Untersuchung der Variationen in der MIA3-Region und ihre Resultate zeigten eine Assoziation des Einzelnukleotidpolymorphismus rs17465637 (C>A) sowie zweier Haplotypen, die beide das Risikoallel (C-Allel) des rs17465637 tragen, mit dem Myokardinfarkt. Diese Befunde liefern einen klaren Beleg für die kardiovaskuläre Bedeutung des MIA3-Gens. The factor melanoma inhibitory activity 3 (MIA3) has been linked with tumour suppression and atherosclerosis. Genome-wide scans have pointed to a possible role of isolated variations in the MIA3 gene in diseases of coronary arteries. This work made an essential contribution to a systematic survey of variation in the MIA3 region and its results showed association of the single nucleotide polymorphism rs17465637 (C>A) and two haplotypes, both of which carry the risk allele (C allele) of rs17465637, with myocardial infarction. These findings offer clear evidence for a cardiovascular impact of the MIA3 gene.

Dies ist eine retrospektive Studie von 220 Patienten mit akutem Myokardinfarkt, die nach sechs Tagen eine kardiale Magnetresonanztomographie erhielten. Die Analyse der Elektrokardiogramme (EKG) ergab, dass Unterschiede in der Sensitivität der geläufigen EKG-Definitionen bei der Erkennung des akuten Myokardinfarkts bestehen. Zusätzliche linksdorsale und rechtspräkordiale EKG-Ableitungen erhöhten nicht die Gesamtsensitivität zum Nachweis eines Infarktes. Die Sensitivität der rechtspräkordialen Ableitungen zum Nachweis von rechtsventrikulären Infarkten war gering. Bei den meisten Patienten mit STEMI lag ein transmuraler Infarkt vor, aber auch bei der Hälfte der Patienten mit NSTEMI fand sich in der Magnetresonanztomographie das Bild eines transmuralen Infarktes. This is a retrospective study of 220 patients with acute myocardial infarction who underwent cardiac magnetic resonance imaging after six days. The analysis of the electrocardiogram (ECG) showed differences in the sensitivity of the standard ECG definitions in the detection of acute myocardial infarction. Additional extended posterior and right precordial leads did not improve the overall sensitivity for the detection of infarction. The sensitivity of right precordial leads for the detection of right ventricular infarction was low. Most patients with STEMI had a transmural infarction but also half of the patients with NSTMI showed a transmural infarction in the magnetic resonance imaging.

Medizin und Gesundheit ,ddc:610 - Abstract
Sphingosin und Sphingosin-1-Phosphat (S1P) sind wichtige Signalmoleküle in verschiedenen zellulären Prozessen. Thrombozyten spielen eine entscheidende Rolle im Sphingolipid-Metabolismus. Sie tragen zur Entstehung von S1P bei und sind der Hauptort der Phosphorylierung des S1P-Rezeptoragonisten FTY 720. In den durchgeführten Experimenten konnte gezeigt werden, dass die Funktion humaner und muriner Thrombozyten durch Stimulation von S1P-Rezeptoren entscheidend beeinflusst und deren Aggregation gehemmt wird. Der Effekt wird im Wesentlichen vermittelt durch die S1P1- und S1P3- Rezeptoren. Die erhobenen Daten erweitern unser bisheriges Verständnis zur Regulation der Thrombozytenfunktion. Sphingosine and sphingosine-1-phosphate (S1P) are important signalling molecules in various cellular processes. Thrombocytes play an essential role in the sphingolipid metabolism. They contribute to the S1P supply in the body and are the main source of FTY 720-phosphate. The experiments indicate that stimulation of S1P receptors affects the function of human and murine thrombocytes and inhibits platelet aggregation. This effect seems to be mediated by S1P1 and S1P3 receptors. The compiled data contribute to our understanding of the regulation of thrombocyte function.

In dieser Arbeit konnte gezeigt werden, dass die kontrastverstärkte Magnetresonanztomographie (k-MRT) die Erkennung einer Herzbeteiligung im Rahmen des HES in verschiedenen Erkrankungsstadien ermöglicht. Das charakteristische Muster der Kontrastmittelanreicherung bei eosinophiler Schädigung ist auf das Endokard begrenzt und findet sich in den apikalen Regionen beider Ventrikel mit unterschiedlich starker Ausdehnung hin zu den basalen Myokardabschnitten. In der Akutphase der Erkrankung findet sich häufig eine Obstruktion des distalen Cavums, was durch eine kontrastmittelaufnehmende Verdickung des regionalen Endokards oder durch Thrombusformationen bedingt ist. Die k-MRT kann die zugrundeliegenden Pathologien, wie die Entzündungsreaktion in der Akutphase bzw. die Fibrose in der chronischen Phase der Löffler-Endokarditis, direkt darstellen und liefert somit wichtige Informationen für den Nachweis einer kardialen Beteiligung. Das Kontrastmittelmuster ist pathognomonisch für diese Erkrankung und unterscheidet sich deutlich von anderen Entitäten, die mit Anreicherung von Kontrastmittel in der k-MRT einhergehen. This study showed that in patients with Hypereosinophilic Syndrome, contrast-enhanced Cardiovascular Magnetic Resonance Imaging (CE-CMR) provides detection of cardiac involvement at different stages of the disease. Late gadolinium enhancement (LGE) was typically restricted to the endocardium and located circumferentially within the right and left ventricular apex. Extension of LGE towards the basal parts of the heart varied among patients, while the outflow tracts were commonly spared. Furthermore, a partial apical obstruction either by thrombus formation or thickened enhanced endocardium was present in those patients with a short history of symptom onset. CE-CMR has the ability to visulize directly the underlying pathologies of myocardial damage such as inflammation in the early stage respectively fibrosis in the chronic stage of Loeffler's endocarditis and generates information for the evidence of cardiac involvement. The pattern of LGE is pathognomic of this disease and the findings clearly differ from the distribution of LGE in other cardiac entities.

Ziel dieser Studie war es herauszufinden, ob das Allel O1 des ABO-Systems Schutz gegenüber einem Myokardinfarkt bietet. Hierzu wurden 793 konsekutive, angiographisch untersuchte Patienten mit akutem oder vorausgegangenem Myokardinfarkt (MI) in die Studie eingeschlossen. Als Kontrollgruppe dienten 340 angiographisch untersuchte Patienten ohne Erkrankung der Koronararterien oder Anzeichen eines Myokardinfarkts.Bei O1-Allel-Trägern war das MI Risikos um 39 % (Odds Ratio 0,61 [95% Konfidenzintervall, 0,41-0,91]) reduziert. Ein multivariates Model, das eine Kodominanz voraussetzt, zeigte, dass ein Anstieg der Anzahl von O1 Allelen mit einer Abnahme des MI Risikos assoziiert ist. Zudem konnte in einer gesonderten Kontrollgruppe (n=164) gezeigt werden, dass der Plasmaspiegel des von Willebrand-Faktors mit der Anzahl der O1 Allele (P=0,00003) in einer Beziehung steht. An association between ABO blood group and myocardial infarction (MI) has been described.We conducted this genetic study to test whether the ABO O1 allele is associated with a reduced risk of Ml. Cases consisted of 793 consecutive, angiographically examined patients with either acute or prior Ml. As controls served 340 angiographically examined patients with neither coronary artery disease nor signs of Ml.O1 allele carriage was associated with a 39% reduction in the risk of Ml unadjusted odds ratio, 0.61; 95% confidence interval, 0.41-0.91). The significant association was maintained after adjustment for other cardiovascular risk factors.

- Abstract
Background: The association between left ventricular ejection fraction (LVEF) change (ΔLVEF) following percutaneous coronary intervention (PCI) and the long-term mortality rate in patients with coronary artery disease is incompletely investigated. We aimed to assess the impact of PCI on LVEF and the association of ΔLVEF after PCI with the long-term mortality rate., Methods and Results: This observational study included 8181 patients with paired angiographic LVEF measurements performed at baseline and 6 to 8 months following the index PCI. ΔLVEF was defined as LVEF measured on the 6- to 8-month angiography minus LVEF measured on the baseline angiography. LVEF change was classified according to the following categories: reduced (ΔLVEF <0), mildly improved (ΔLVEF >0% to <10%) and largely improved (ΔLVEF ≥10%). The primary outcome was the 5-year mortality rate. In patients with baseline LVEF <40%, 40% to <50% and ≥50%, ΔLVEF (median [25th-75th percentiles]) was 6.0% [0.0% to 14.0%], 4.0% [-1.0% to 11.0%] and 0.0% [-4.0% to 3.0%], respectively ( P <0.001). In patients with reduced, mildly improved, and largely improved ΔLVEF, the 5-year mortality rate (n=712) was 29.1%, 23.1%, and 16.5%, respectively, in patients with baseline LVEF <40%; 17.0%, 12.2% and 9.8%, respectively, in patients with baseline LVEF 40% to <50%; and 7.8%, 7.1%, and 5.6%, respectively, in patients with baseline LVEF ≥50% (adjusted hazard ratio [HR], 0.91 [95% CI, 0.86-0.96]; P <0.001) for all-cause death and adjusted (HR, 0.86 [95% CI, 0.81-0.92]; P <0.001) for cardiac death, calculated for 5% higher ΔLVEF., Conclusions: In patients with coronary artery disease undergoing PCI, improvement of LVEF following PCI was associated with a reduced long-term mortality rate in patients with reduced LVEF but not in patients with preserved LVEF before intervention.
