Paclitaxel-eluting versus uncoated stents in primary percutaneous coronary intervention.

Background: Drug-eluting coronary-artery stents have been shown to decrease restenosis and therefore the likelihood that additional procedures will be required after percutaneous coronary intervention (PCI). We evaluated the use of a drug-eluting stent in patients undergoing PCI for acute myocardial infarction with ST-segment elevation.

Methods: We randomly assigned 619 patients presenting with an acute myocardial infarction with ST-segment elevation to receive either a paclitaxel-eluting stent or an uncoated stent.

Hypothermia resulting in characteristic ECG changes mimicking an acute myocardial infarction: Osborn waves and atrial fibrillation.

Hypothermia can cause several ECG changes which can be mistaken for other cardiac diseases, most importantly acute transmural ischaemia. These ECG changes correlate strongly with the degree of hypothermia and the prognosis of the patient. This brief report presents a 32-year-old male who was seen after a drowning accident.

Early discharge is feasible following primary percutaneous coronary intervention with transradial stent implantation under platelet glycoprotein IIb/IIIa receptor blockade. Results of the AGGRASTENT Trial.

Background: Primary percutaneous coronary intervention (PCI) with stent implantation demonstrated to be superior to both PCI with balloon angioplasty and to thrombolysis for acute ST-elevation myocardial infarction (STEMI). The use of glycoprotein (GP) IIb-IIIa blockers in this setting may be beneficial. However, GP IIb-IIIa receptor blocker treatment is frequently accompanied by femoral entry site-related bleeding complications, resulting in additional morbidity and prolonged hospitalization.

Lack of efficacy of clopidogrel pre-treatment in the prevention of myocardial damage after elective stent implantation.

Objectives: The object of this study was to determine the effect of pre-treatment with clopidogrel in patients undergoing elective stent implantation.

Background: The treatment of patients with adenosine diphosphate receptor blockers after percutaneous coronary intervention (PCI) with stent implantation has been shown to decrease the incidence of subacute stent thrombosis. Furthermore, non-randomized studies on pre-treatment with clopidogrel among patients undergoing stent implantation have suggested a reduction in myocardial damage and clinical events.

Successful aortic valve replacement in a patient with AIDS.

In trying to assess the benefit of cardiac surgery in AIDS patients, the question arises whether a patient with a deficient immune system can tolerate open heart surgery well enough to make the operation worthwhile. Surgical procedures and cardiopulmonary bypass have been noted to alter immune function (Diettrich et al., Ide et al.
