Aims Intra-aortic balloon counterpulsation (IABP) in ST-segment elevation myocardial infarction (STEMI) with cardiogenic shock is strongly recommended (class IB) in the current guidelines. We performed meta-analyses to evaluate the evidence for IABP in STEMI with and without cardiogenic shock. Methods and results Medical literature databases were(More)
Currently, the most used left ventricular (LV) support device is intra-aortic balloon counterpulsation. The percutaneous implantable Impella Recover LP 2.5 system is a novel LV (unloading) assist device. We studied the feasibility and safety of LV support with the percutaneous implantable Impella Recover LP 2.5 system in 19 consecutive high-risk patients(More)
BACKGROUND Despite rapid dissemination of an everolimus-eluting bioresorbable scaffold for treatment for coronary artery disease, no data from comparisons with its metallic stent counterpart are available. In a randomised controlled trial we aimed to compare an everolimus-eluting bioresorbable scaffold with an everolimus-eluting metallic stent. Here we(More)
AIMS In patients with obstructive coronary artery disease (CAD), the growth of collateral arteries, i.e. arteriogenesis, can preserve myocardial tissue perfusion and function. Monocytes modulate this process, supplying locally the necessary growth factors and degrading enzymes. Knowledge on factors involved in human arteriogenesis is scarce. Thus, the aim(More)
Percutaneous coronary interventions (PCI) have become a reliable revascularisation option to treat ischaemic coronary artery disease. Drug-eluting stents (DES) are widely used as first choice devices in many procedures due to their established good medium to long term outcomes. These permanent implants, however, do not have any residual function after(More)
BACKGROUND Primary percutaneous coronary intervention (PCI) reduces mortality in patients with ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS). Despite PCI, mortality in CS is still approximately 50%. Admission glucose concentration is an independent predictor of mortality in patients with STEMI and is associated(More)
BACKGROUND Bioresorbable vascular scaffolds were developed to overcome the shortcomings of drug-eluting stents in percutaneous coronary intervention (PCI). We performed an investigator-initiated, randomized trial to compare an everolimus-eluting bioresorbable scaffold with an everolimus-eluting metallic stent in the context of routine clinical practice.

In acute ST-elevation myocardial infarction (STEMI), patients with multivessel disease (MVD) are considered to be a subgroup with an increased risk of mortality compared with patients with single-vessel disease (SVD). To evaluate the effect of MVD on 1-year mortality in patients with STEMI, we studied 1,417 consecutive patients with STEMI who were admitted(More)
OBJECTIVES The purpose of this study was to evaluate the effectiveness of combined proximal embolic protection with thrombus aspiration (Proxis Embolic Protection System [St. Jude Medical, St. Paul, Minnesota]) in ST-segment elevation myocardial infarction patients. BACKGROUND Embolization during primary percutaneous coronary intervention (PCI) may result(More)
BACKGROUND Routine thrombus aspiration is frequently used during primary percutaneous coronary intervention in patients with ST-elevation myocardial infarction to prevent distal embolization. Recently, evidence of clinical benefit was published. In 50% of the ST-elevation myocardial infarction patients with an onset of symptoms <12 hours before, thrombi(More)
