Drug eluting and bare metal stents in people with and without diabetes: collaborative network meta-analysis

Objective To compare the effectiveness and safety of three types of stents (sirolimus eluting, paclitaxel eluting, and bare metal) in people with and without diabetes mellitus

Nightmare-Induced Atypical Midventricular Tako-Tsubo Cardiomyopathy

Tako-Tsubo cardiomyopathy (TTC) is a reversible cardiomyopathy characterized by acute left ventricular segmental dysfunction, whose clinical presentation resembles that of acute myocardial infarction. The syndrome often follows a psychophysical stressful event and is characterized by echocardiographic evidence of akinesia of the left ventricular mid-apical segments. Atypical echocardiographic patterns of TTC have recently been described, often triggered by emotional stressors, rather than physical. In this report, we describe a case of atypical TTC triggered by an unusual stressor (recurrent nightmare) in a 45-year-old woman, with peculiar clinical presentation and evolution characterized by persistent loss of consciousness, neurological deterioration, absence of typical symptoms of TTC, and features suggestive of a hysterical crisis

Single-center randomized evaluation of paclitaxel-eluting versus conventional stent in acute myocardial infarction (SELECTION)

Objectives: To evaluate the superiority of the paclitaxel-eluting stent (PES) in reducing neointimal hyperplasia (NIH) over its corresponding bare metal stent (BMS) during primary percutaneous coronary intervention (PCI). Background: Primary PCI with stent implantation is the repercussion strategy of choice for ST-elevation myocardial infarction (STEMI); nonetheless restenosis rate is still high. Drug-eluting stents have been proven to reduce restenosis rate in many settings, but their use during primary PCI is still controversial. Methods: Consecutive patients with STEMI <12 hours were randomized to receive PES or BMS. The primary end-point was the percentage of the stent volume obstructed by neointimal proliferation (NIH) measured by intravascular ultrasound (IVUS) at a 7-month angiographic follow-up. Secondary end-points were binary restenosis rate and major adverse cardiac events (MACE, i.e., death, nonfatal myocardial infarction, and target lesion revascularization). Results: Eighty patients with STEMI were randomized into the PES or BMS group. Patients were well matched for baseline characteristics and the index procedure was always successful. In-hospital and 1-month MACE were 2.5% per group. NIH at 7 months was 4.6% versus 20% (P<0.01), late lumen loss 0.1 versus 1.01 mm (P = 0.01). MACE were 7.5% versus 42.5% (P = 0.001) with no difference in death and recurrent myocardial infarction rates. Late-acquired incomplete stent apposition (ISA) rate was 5.1% versus 2.7% (P = 0.65). One subacute stent thrombosis was reported in each group. Conclusions: PES was superior to its corresponding BMS in reducing NIH in the STEMI setting without any increase in early and long-term clinical adverse events. (J Interven Cardiol 2007;20:282-291
