PURPOSE To perform a meta-analysis to compare the diagnostic performance of 16- versus 64-section computed tomography (CT) for the diagnosis of coronary artery disease (CAD). MATERIALS AND METHODS The MEDLINE database was searched for relevant original articles. Criteria for inclusion of articles were (a) use of multisection spiral CT as a diagnostic test(More)
PURPOSE To perform a meta-analysis to evaluate the accuracy of 16- and 64-section spiral computed tomography (CT) to help assess coronary artery bypass grafts (CABGs). MATERIALS AND METHODS The MEDLINE, Cochrane library, and BioMed Central databases were searched for relevant original articles published up to May 2007. Major criteria for article inclusion(More)
A prospective, multicenter trial was conducted in patients with nontraumatic chest pain in 4 hospitals to determine whether an 80-lead body surface map electrocardiogram system (80-lead BSM ECG) improves detection of ST-segment elevation in acute myocardial infarction (STEMI) compared with a standard 12-lead electrocardiogram (ECG) in an emergency(More)
UNLABELLED Early detection of acute myocardial infarction (MI) is vital in the management of acute coronary syndromes (ACS). Hence we compared the diagnostic capability of the standard 12-lead electrocardiogram (ECG) with the 80-lead ECG body surface map (BSM) prehospital. METHODS Consecutive patients (n = 294) presenting prehospital with ischemic type(More)
This study was designed to define the current role of multislice spiral computed tomography (MSCT) for the diagnosis of coronary in-stent restenosis using a meta-analytic process. Restenosis remains a limitation after coronary stent implantation and contributes to a substantial number of coronary re-assessments by conventional invasive coronary angiography(More)
Case Presentation: A 55-year-old man was admitted for investigation of a persistent cough. Chest x-ray revealed an opacity near the right upper-lobe bronchus. He was an exsmoker, and his only previous medical history was of an acute coronary syndrome leading to the implantation of a drug-eluting stent (DES) in his proximal left anterior descending artery 3(More)
AIMS The causative relationship between major bleeding in acute coronary syndromes (ACS) and the increase in mortality and morbidity has frequently been suggested in recent pharmaco-invasive trials and registries. However, the magnitude of this increased risk is the subject of debate. In order to determine the prognostic significance of major bleeding in(More)
We prospectively evaluated a rapid-access chest pain clinic in terms of clinical diagnoses, outcomes, morbidity and mortality at 3 months follow-up in patients, and cost-effectiveness. All patients seen at the clinic from February 1999 to December 2000 were assessed. Referring doctors indicated the management they would have provided had the clinic been(More)
OBJECTIVE The objective of this study was to examine the relationship between right ventricular involvement (RVI) in acute myocardial infarction (AMI) and the increase in mortality and morbidity frequently suggested in the last two decades. DESIGN The authors conducted a systematic review and meta-analysis. SETTING This study was conducted at an(More)
