OBJECTIVES The aim of this multicenter, multinational, prospective, observational study was to assess the relative value of myocardial viability and induced ischemia early after uncomplicated myocardial infarction. BACKGROUND Dobutamine-atropine stress echocardiography allows evaluation of rest function (at baseline), myocardial viability (at low dose)(More)
OBJECTIVE Coronary artery disease (CAD) is a leading cause of mortality and morbidity in diabetic patients; therefore, their risk stratification is a relevant issue. Because exercise tolerance is frequently impaired in these patients, pharmacological stress echocardiography (SE) has been suggested as a valuable alternative. Our aim was to evaluate the(More)
AIM A relative excess of fat in the upper body region has been proven to be associated with increased coronary artery disease (CAD) risk. Dual-energy X-ray absorptiometry (DXA) is probably the most accurate and precise method available to study fat regional distribution and to directly measure total body fat and lean soft tissue mass. However, while several(More)
BACKGROUND Although appropriateness criteria for stress echocardiography have been developed to deliver high-quality care, the prognostic impact of these criteria remains undefined. Therefore, we sought to assess the prognostic implication of the American College of Cardiology/American Society of Echocardiography appropriateness criteria for pharmacological(More)
OBJECTIVES This study sought to test the hypothesis that thrombus removal, with a new manual thrombus-aspirating device, before primary percutaneous coronary intervention (PPCI) may improve myocardial reperfusion compared with standard PPCI in patients with ST-segment elevation acute myocardial infarction (STEMI). BACKGROUND In STEMI patients, PPCI may(More)
BACKGROUND The aim of this study was to determine whether antianginal medications affect the prognostic value of pharmacological stress echocardiography. METHODS AND RESULTS From the EPIC-EDIC Data Bank, 7333 patients (5452 men; age; 59+/-10 years) underwent pharmacological stress echocardiography with either high-dose dipyridamole (0.84 mg/kg over 10(More)
Diagnostic tests that are hazardous or infeasible, or both, may become accepted before inadequacies are recognised; only multicentre trials can provide the necessary information for an unrestricted acceptance of any new diagnostic procedure. We prospectively studied the results obtained in 24 experienced echocardiography laboratories. 2949 tests were done(More)
AIMS Risk stratification after uncomplicated acute myocardial infarction is mostly applied by either symptom-limited post discharge exercise electrocardiography or pre-discharge submaximal exercise test. Aim of the present study was to determine if early pharmacological stress echocardiography and discharge within 24 hours of the test in cases without(More)
BACKGROUND Residual viable myocardium identified by dobutamine stress after myocardial infarction may act as an unstable substrate for further events such as subsequent angina and reinfarction. However, in patients with severe global left ventricular dysfunction, viability might be protective rather than detrimental. The aim of this study was to assess the(More)
Exercise electrocardiography (ECG) is of limited usefulness in hypertensive patients, whereas pharmacologic stress echocardiography can provide diagnostic and prognostic information. The aim of this study was to compare the prognostic value of clinical data, exercise ECG, and pharmacologic stress echocardiography in hypertensive patients with chest pain and(More)
