High negative predictive value of workload ≥7 METS on exercise testing in patients with normal gated myocardial perfusion imaging: Was imaging really required?
Introduction: Good functional capacity has a high negative predictive value (NPV) in patients with known or suspected coronary artery disease (CAD) similar to a normal gated myocardial perfusion imaging (GMPI). Aim of this study was to evaluate NPV of functional capacity during treadmill exercise in patients with normal GMPI in Pakistani population. Methods: This was a prospective study which ...
متن کاملNegative predictive value of the Duke criteria for infective endocarditis.
With use of new Duke criteria, 405 episodes of suspected endocarditis were previously classified as "definite," "possible," or "rejected" endocarditis. To determine the negative predictive value of the Duke clinical criteria for the classification of suspected endocarditis, chart review and follow-up were performed for the 52 episodes in which the diagnosis of endocarditis was rejected. Three o...
متن کاملImproving the positive predictive value of exercise testing in women.
OBJECTIVE To identify exercise test variables that can improve the positive predictive value of exercise testing in women. DESIGN Cohort study. SETTING Regional cardiothoracic centre. SUBJECTS 1286 women and 1801 men referred by primary care physicians to a rapid access chest pain clinic, of whom 160 women and 406 men had ST depression of at least 1 mm during exercise testing. The results...
متن کاملRisk assessment and predictive value of coronary artery disease testing.
This review highlights and compares risk assessment, predictive accuracy, and economic outcomes for 3 commonly applied cardiac imaging procedures: stress myocardial perfusion SPECT or PET and coronary CT angiography (CCTA). This review highlights an expansive evidence base for stress myocardial perfusion imaging and reveals a decided advantage for higher-risk patients, notably those who have es...
متن کاملPreschool vision screening: negative predictive value for amblyopia.
BACKGROUND/AIMS Single optotype tests of visual acuity are widely used for preschool vision screening in order to optimise cooperation with testing. These tests may, however, underestimate the visual acuity deficit in amblyopia because they lack visual crowding. This study assessed the resultant negative predictive value (NPV) for amblyopia. METHODS Cohort study of 936 children in the Cambrid...
