There is conflicting information about gender differences in presentation, treatment, and outcome after acute ST elevation myocardial infarction (STEMI) in the era of thrombolytic therapy and primary percutaneous coronary intervention. From June 1994 to January 1997, we enrolled 6,067 consecutive patients with STEMI admitted to 54 hospitals in southwest(More)
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(More)
Networked activity trackers have become an important tool for assessing physical activity, as part of behavior change interventions, within epidemiological studies, or driven by personal interest. However the use of activity trackers is often abandoned after a few months, and their effect on health behavior is unclear. We conducted a longitudinal study(More)
As old patients, who were treated by percutaneous coronary interventions (PCI) for ST-segment elevation myocardial infarction (STEMI), are regularly excluded or underrepresented in randomized trials, data on treatment and outcomes of this patient group at high risk have to be collected by registries. The study population of the German Bremen STEMI Registry(More)
Chronic total coronary occlusions (CTOs) represent a subgroup of coronary lesions with a low procedural success and high recurrence rate. However, there is evidence for a prognostic benefit of revascularizing a CTO. This study assessed the prevalence of CTOs among patients with stable angina pectoris and its impact on therapeutic strategies. Between 2001(More)
OBJECTIVES To assess the safety and effectiveness of abciximab in patients with ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) in clinical practice. METHODS Data were analysed of 2184 consecutive patients treated with primary PCI for acute STEMI and either concomitant abciximab or no glycoprotein(More)
OBJECTIVES We investigated changes in the clinical outcome of primary angioplasty and thrombolysis for the treatment of acute myocardial infarction (AMI) from 1994 to 1998. BACKGROUND Primary angioplasty for the treatment of AMI is a sophisticated technical procedure that requires experienced personnel and optimized hospital logistics. Growing experience(More)
Patienten mit Diabetes mellitus haben beim akuten Myokardinfarkt (AMI) möglicherweise geringere Beschwerden oder häufiger asymptomatische Infarkte. Dies ist eine verbreitete klinische Auffassung. Daten zweier Register ins Krankenhaus aufgenommener AMI-Patienten (MITRA PLUS mit 18786 Patienten; Norddeutsches Register, NGR, 1042 Patienten mit detailiertem(More)
INTRODUCTION Laws banning tobacco smoking from public areas have been passed in several countries, including the region of Bremen, Germany at the end of 2007. The present study analyses the incidence of hospital admissions due to ST-elevation myocardial infarctions (STEMIs) before and after such a smoking ban was implemented, focusing on differences between(More)
In randomized clinical trials, low-molecular-weight heparin enoxaparin has been shown to decrease ischemic complications in patients with acute coronary syndromes (ACSs) without ST elevations who are treated conservatively. Enoxaparin has been shown to be equally effective as unfractionated heparin in high-risk patients with an early invasive approach.(More)
