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...

Percutaneous coronary intervention (PCI) has become the default therapy for obstructive coronary artery disease and invariably involves coronary stenting. Currently, stenting with a drug-eluting stent (DES) has become the default method for intervention, with few exceptions.1 The major drawback of this strategy is both acute and subacute stent thrombosis. The DES type, positioning, and lesion complexity may all contribute to stent thrombosis, the mechanisms of which are still under investigation.2 While there may be some debate as to the absolute occurrence of stent thrombosis, the complicatio...

Electrophysiology 2009: Making Practical Decisions in Difficult Economic Times

Guest Editor:
Todd J. Cohen, MD, FACC, FHRS

Electrophysiology continues to make advances. However, we have to place these advances in the context of an economy that has slipped into a deep recession (both in the United States and worldwide). For years, electrophysiology has seen double-digit growth in both the number of devices implanted as well as the number of catheter ablation procedures performed. This growth has been unprecedented and coincided with the growth seen on Wall Street and in technology over the past thirty years. As companies like Microsoft and Intel continued to grow and expand, so did the cardiovascular technology com...

ABSTRACT: Objectives. The present study was designed to delineate and compare the clinical characteristics of patients with apical and non-apical takotsubo syndrome in a high-volume U.S. hospital. Background. A comparison between apical and non-apical variants of the “broken heart,” or takotsubo syndrome, has not been performed in the United States. Methods. From 2004 through 2007, patients with takotsubo syndrome were identified according to the following criteria: acute chest pain with electrocardiographic changes or elevation of cardiac enzymes, absence of significant coronary narrowing...

In this issue of the Journal, Jabara et al1 provide an intriguing summary of differences between apical and non-apical Tako-tsubo syndrome based on case summaries of individuals with most often stress-induced ischemic events in the absence of major coronary vessel obstruction. The apical-type disorders are associated with larger defects, and not surprisingly, more severe complications. The apical patients probably show more intense ischemia with greater amounts of jeopardized muscle, and thus, the consequences of the ischemic insult are greater. Non-apical events appear more benign, presumably...

There have been major advances in the field of percutaneous coronary intervention (PCI) since its introduction 30 years ago. The improved safety and outcomes can be attributed to increasing operator experience, advances in device technology and the pivotal role of adjunctive pharmacotherapy. Despite these advances, challenges remain that require further research and development. One such challenge is the treatment of thrombotic lesions. Coronary artery thrombus commonly develops following rupture of an atherosclerotic plaque and undergoes modifications in terms of size and composition over tim...
