Impact of prehospital delay on mortality in patients with acute myocardial infarction treated with primary angioplasty and intravenous thrombolysis.

2001

Abstract Background In patients with acute myocardial infarction treated with thrombolysis, longer times to treatment are associated with increasingly worse clinical outcome. This relation may be different for treatment with primary angioplasty. Methods We analyzed the pooled data of the German acute myocardial infarction registries Maximal Individual Therapy in Acute Myocardial Infarction (MITRA) and Myocardial Infarction Registry (MIR) to determine the influence of prehospital delays on hospital mortality rates. Primary angioplasty was performed in 1063 patients and thrombolysis in 7552 patients. Results In patients treated with thrombolysis, in-hospital time to treatment was constantly 3…

Everolimus eluting bioresorbable vascular scaffolds in patients with acute coronary syndromes: Two‐year results from the German‐Austrian ABSORB regis…

2021

Abstract Objectives To identify potential differences in 2‐year outcome between patients who underwent coronary revascularization using bioresorbable vascular scafffolds (BVS) in stable coronary artery disease (CAD) and acute coronary syndromes (ACS). Background Data from randomized trials suggest a significantly higher event rate following coronary revascularization using everolimus‐eluting BVS as compared to new generation drug eluting stents. Whether particular patient subgroups are at increased risk for scaffold thrombosis and target lesion failure (TLF) has not clearly been demonstrated. Methods German‐Austrian ABSORB RegIstRy is a prospective all‐comer multi‐center observational study…

Predictors of early scaffold thrombosis: results from the multicenter prospective German-Austrian ABSORB RegIstRy.

2018

BACKGROUND In randomized clinical trials, the risk of thrombotic events with the absorb bioresorbable vascular scaffold (BVS) was significantly higher than with metallic drug-eluting stents. We evaluated predictors of scaffold thrombosis in the large-scale, multicenter German-Austrian ABSORB RegIstRy. METHODS AND RESULTS 3178 patients with treatment of 4252 lesions using 5020 scaffolds were included. Follow-up rate at 6 months was 97.4%. Forty-five (1.42%) patients experienced definite/probable scaffold thrombosis during follow-up. Multiple regression analysis showed implantation of absorb BVS in bifurcation lesions [odds ratio (OR): 4.43; 95% confidence interval (CI): 1.69-11.59; P=0.0024]…

Evaluation of the short- and long-term safety and therapy outcomes of the everolimus-eluting bioresorbable vascular scaffold system in patients with …

2015

Abstract Background Third-generation drug-eluting metal stents are the gold standard for treatment of coronary artery disease. The permanent metallic caging of the vessel, however, can result in limited vasomotion, chronic inflammation, and late expansive remodeling, conditions that can lead to late and very late stent thrombosis. The development of bioresorbable scaffolds (BRSs) promises advantages over metal stents due to complete biodegradation within 2–4 years. Theoretically, since vessel scaffolding is temporary and no permanent implant remains in the vessel, BRSs, as opposed to metal stents, once degraded would no longer be potential triggers for stent-related adverse events or side e…

Predictors of scaffold failure and impact of optimized scaffold implantation technique on outcome: Results from the German-Austrian ABSORB RegIstRy.

2021

Aims We aimed to investigate predictors of scaffold failure and the potential impact of an optimized scaffold implantation technique by means of a learning curve on long-term clinical outcome after bioresorbable scaffold (BRS) implantation and to evaluate predictors of scaffold failure. Methods and results A total of 3326 patients were included in this prospective, observational, multi-center study (ClinicalTrials.gov NCT02066623) of consecutive patients undergoing BRS implantation between November 2013 and January 2016. The 3144 patients completed follow-up after 24 months, 3265 patients were eligible for time-to-event-analysis. Clinical endpoints were major adverse cardiac events-a compos…

Impact of left atrial diameter on outcome in patients undergoing edge-to-edge mitral valve repair: results from the German TRAnscatheter Mitral valve…

2020

Abstract Background Left atrium (LA) dimension is a marker of disease severity and outcome in primary and secondary mitral regurgitation. In transcatheter mitral valve repair LA enlargement might additionally impact on device handling and technical success through an altered anatomy and atrial annular dilatation. Methods Data from the multicenter German transcatheter mitral valve intervention registry “TRAMI” were used to analyse the association of baseline LA diameter by tertiles and efficacy, safety and long-term clinical outcome in patients undergoing edge-to-edge repair with the MitraClip. Results In 520 of 843 patients prospectively enrolled in TRAMI baseline LA diameter were reported …

Safety and efficacy of MitraClip™ therapy in patients with severely impaired left ventricular ejection fraction: results from the German transcathete…

2017

Aims The aim of the present study was to assess the safety and efficacy of percutaneous mitral valve repair using the MitraClip™ device in patients with severely reduced systolic left ventricular (LV) function. Methods and results Among 777 MitraClip™ implantations included in the German mitral valve registry, we identified 256 patients suffering from severely reduced LV function [ejection fraction (EF) 50%) and 280 patients presenting with an EF 30–50% prior to MitraClip™ therapy. High procedural success rates, low periprocedural complication rates, and low residual mitral regurgitation grades at discharge were achieved throughout all groups. In-hospital mortality was low and comparable in…

Primär-Dilatation versus Thrombolyse bei Patienten mit akutem Myokardinfarkt, die nicht in randomisierte Studien eingeschlossen wurden

1999

Die randomisierten Studien zum Vergleich der Thrombolyse und der Primar-Dilatation beim akuten Myokardinfarkt schlossen keine Patienten mit Linksschenkelblock, nichtdiagnostischem ersten Elektrokardiogramm, einer Prahospitalzeit von ≥ 12 h oder einer unbekannten Prahospitalzeit ein. Im klinischen Alltag werden jedoch haufig solche Patienten mittels Thrombolyse oder Primar-Dilatation behandelt. Um diese Patientengruppen zu beschreiben und den Einflus der Lyse und der Primar-Dilatation zu vergleichen, untersuchten wir die Daten aus der “Maximale Individuelle Optimierte Therapie beim Akuten Myokardinfarkt” (MITRA)-Studie. Bei 737 von 3308 (22,3 %) mittels Primar-Dilatation oder Lyse behandelte…

Reliability and Accuracy of Echocardiography for Follow-up Studies after Intervention

1987

By two-dimensional echocardiography limitations of M-mode echocardiography have been eliminated. As a direct and noninvasive method two-dimensional echocardiography seems to be an ideal method for analysis of left ventricular function in follow-up studies. In relation to other methods there are no limitations concerning x-ray exposure, physicians and patients safety. Before different studies can be discussed, reliability and accuracy of two-dimensional echocardiography have to be evaluated. Beat-to-beat, day-to-day, intra- and interobserver variability will be discussed, followed by description of follow-up studies after intervention.

2019

The limitations of the first-generation everolimus-eluting coronary bioresorbable vascular scaffolds (BVS) have been demonstrated in several randomized controlled trials. Little data are available regarding the outcomes of patients receiving hybrid stenting with both BVS and drug-eluting stents (DES). Of 3144 patients prospectively enrolled in the GABI-Registry, 435 (age 62 &plusmn

Primary percutaneous transluminal coronary angioplasty for Acute Myocardial Infarction in patients not included in randomized studies

1999

Abstract Patients with acute myocardial infarction included in randomized trials comparing primary percutaneous transluminal coronary angioplasty (pPTCA) with thrombolysis represent a special subgroup of patients with a low event rate. Patients excluded from these trials represent a variety of different subgroups, with different patient characteristics and possibly different clinical event rates. Primary PTCA was performed in 491 consecutive patients with acute myocardial infarction in the prospective multicenter observational Maximal Individual Therapy in Acute Myocardial Infarction trial. They were divided into the following groups: group I, patients fulfilling the inclusion criteria of t…

Primary angioplasty versus intravenous thrombolysis in acute myocardial infarction: can we define subgroups of patients benefiting most from primary …

2001

Abstract OBJECTIVES We sought to determine the effectiveness of primary angioplasty compared with thrombolysis in clinical practice. BACKGROUND In clinical practice, primary angioplasty for the treatment of acute myocardial infarction (AMI) has not yet been proven more effective than intravenous thrombolysis, nor have subgroups of patients been identified who would perhaps benefit from primary angioplasty. METHODS The pooled data of two AMI registries—the Maximal Individual TheRapy in Acute myocardial infarction (MITRA) study and the Myocardial Infarction Registry (MIR)—were analyzed. A total of 9,906 lytic-eligible patients with AMI, with a pre-hospital delay of ≤12 h, were treated with ei…

Acute myocardial infarction occurring in versus out of the hospital: patient characteristics and clinical outcome

2000

OBJECTIVES We describe the baseline characteristics and clinical course of patients who had an acute myocardial infarction (AMI) during their hospital stay. BACKGROUND In comparison with patients who had an AMI outside of the hospital (prehospital AMI), the data on patients who had an AMI in the hospital are poorly described. METHODS Patients with an in-hospital AMI were prospectively registered in the Southwest German Maximal Individual TheRapy in Acute myocardial infarction (MITRA) study and compared with patients with prehospital AMI. RESULTS Of 5,888 patients with AMI, 403 patients (6.8%) had an in-hospital AMI. These patients were older, more often male and sicker as compared with the …

Comparison of primary angioplasty with conservative therapy in patients with acute myocardial infarction and contraindications for thrombolytic thera…

1999

The benefit of primary angioplasty in patients with acute myocardial infarction (AMI) and contraindications for thrombolysis compared to a conservative regimen is still unclear. Out of 5,869 patients with AMI registered by the MITRA trial, 337 (5.7%) patients had at least one strong contraindication for thrombolytic therapy. Out of these 337 patients 46 (13.6%) were treated with primary angioplasty and 276 (86.4%) were treated conservatively. Patients treated conservatively were older (70 years vs. 60 years; P = 0.001), had a higher rate of a history with chronic heart failure (14.8% vs. 4.4%; P = 0.053), a higher heart rate at admission (86 beats/min vs. 74 beats/min; P = 0.001), and a hig…

Impact of coronary calcification on outcomes after ABSORB scaffold implantation: insights from the GABI-R registry.

2020

OBJECTIVE To investigate the outcomes after bioresorbable scaffold (BRS) implantation in calcified coronary lesions. In calcified coronary lesions, durable metallic drug-eluting stent (DES) implantation is associated with worse clinical outcomes compared to noncalcified lesions. Although not recommended, BRSs were frequently implanted in calcified lesions in clinical practice. Their outcome is not well investigated. METHODS Between November 2013 and January 2016, 3326 patients were enrolled in the German-Austrian ABSORB ReglstRy (GABI-R). Lesion calcification severity was classified into no (n = 1144), mild (n = 1306), and moderate-to-severe (n = 690) calcification. RESULTS Patients with ca…
