Clinical outcomes in diabetic and non-diabetic patients with drug-eluting stents: results from the first phase of the prospective multicenter German DES.DE registry.

Background: Patients with diabetes mellitus (DM) undergoing coronary revascularization are at increased risk for adverse outcomes. Without sufficiently powered data from diabetic subgroup analyses and in absence of randomized controlled trials in diabetic patients with primary clinical outcomes controversy is ongoing over safety and efficacy of drug-eluting stents (DES) in diabetic patients.

Methods And Results: Between October 2005 and October 2006, 1,659 diabetic and 3,559 non-diabetic patients treated with DES (Paclitaxel or Sirolimus-eluting stents) were enrolled at 98 Drug-Eluting-Stent.

Prevention of left ventricular remodeling with granulocyte colony-stimulating factor after acute myocardial infarction: final 1-year results of the Front-Integrated Revascularization and Stem Cell Liberation in Evolving Acute Myocardial Infarction by Granulocyte Colony-Stimulating Factor (FIRSTLINE-AMI) Trial.

Background: Experimental and clinical evidence has recently shown that pluripotent stem cells can be mobilized by granulocyte colony-stimulating factor (G-CSF) and may enhance myocardial regeneration early after primary percutaneous coronary intervention (PCI) management of acute myocardial infarction. Sustained or long-term effects of mobilized CD34-positive mononuclear stem cells, however, are unknown.

Methods And Results: Thirty consecutive patients with ST-elevation myocardial infarction undergoing primary PCI with stenting and abciximab were selected for the study 85+/-30 minutes after PCI; 15 patients were randomly assigned to receive subcutaneous G-CSF at 10 microg/kg body weight for 6 days in addition to standard care including aspirin, clopidogrel, an angiotensin-converting enzyme inhibitor, beta-blocking agents, and statins.
