OBJECTIVES We sought to evaluate the results of percutaneous coronary intervention (PCI) in elderly patients in contemporary practice. BACKGROUND Prior studies of PCI in the elderly population demonstrate increased in-hospital mortality, but these studies are limited by small population size. METHODS Using the American College of Cardiology-National(More)
OBJECTIVES The aim of this study was to assess the feasibility of evaluation for appropriate use of radionuclide myocardial perfusion imaging (MPI) in multiple clinical sites and to determine use patterns as well as identify areas of apparent inappropriate use. BACKGROUND Although cardiac imaging is highly valued for decision-making, the growth and(More)
The American College of Cardiology Foundation (ACCF), Society for Cardiovascular Angiography and Interventions, Society of Thoracic Surgeons, and the American Association for Thoracic Surgery, along with key specialty and subspecialty societies, conducted an update of the appropriate use criteria (AUC) for coronary revascularization frequently considered.(More)
The mechanical behavior of isolated cat, rat, and dog ventricular muscle was examined during hypoxia and after reoxygenation. During hypoxia, an early abbreviation of tension duration was followed by a decline in the rate of tension development. After reoxygenation, a marked, early prolongation of tension development and relaxation time was invariably(More)
The American College of Cardiology Foundation along with key specialty and subspecialty societies, conducted an appropriate use review of common clinical presentations for stable ischemic heart disease (SIHD) to consider use of stress testing and anatomic diagnostic procedures. This document reflects an updating of the prior Appropriate Use Criteria (AUC)(More)
