ABSTRACT: Background. The frequency of ad hoc percutaneous coronary intervention (PCI) varies among institutions and regions of the country. It is unclear what factors limit use of the ad hoc strategy. Objective. To define factors which limit the use of the ad hoc strategy. Methods. All patients who underwent PCI at our center in 2004 were reviewed. Patients who had emergent PCI for ST-elevation myocardial infarction (n = 188), those who had undergone diagnostic coronary angiography at a referring facility (n = 54), and those who had a repeat PCI after a previous ad hoc PCI (n = 19) were exclu

Preprocedural White Blood Cell Count as a Predictor of Death and Major Adverse Cardiac Events in Patients Undergoing Percutaneous Coronary Intervention with Drug-Eluting Stents
ABSTRACT: Background. Patients with elevated white blood cell (WBC) counts who undergo percutaneous coronary intervention (PCI) are at increased risk for short- and long-term mortality as well as major adverse cardiac events (MACE). We assessed the relationship between elevated WBC counts and clinical events in patients who underwent PCI with drug-eluting stents (DES). Methods. Our retrospecti

Numerous epidemiologic and clinical studies have shown leukocytosis to be an independent predictor of future cardiovascular events.1 While a causal mechanism has yet to be determined, the relationship remains consistent, temporal and dose-dependent in a wide array of patients, ranging from those free of coronary heart disease to those presenting with acute myocardial infarction (MI).2 In the era of percutaneous coronary intervention (PCI), an elevated preprocedural white blood cell (WBC) count has been associated with worse clinical outcomes in patients undergoing angioplasty with or without b

ABSTRACT: Background. Recent data suggest a clinical benefit with the systematic use of thrombus aspiration (TA) for the treatment of ST-elevation myocardial infarction (STEMI). Nevertheless, the impact of TA as a treatment strategy for stent thrombosis (ST) is unknown. This study aimed to analyze the impact of TA use for the treatment of ST on patient outcomes. Methods. From 2003 to 2008, 91 consecutive patients who presented with a definite ST were included in this analysis. We compared procedural success rates and the incidence of the composite criteria death-recurrent MI-recurrent ST at 30
