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)
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)
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)
Aims To compare the prognostic implication of stress echocardiography (SE) in a large cohort of hypertensive and normotensive patients with known or suspected coronary artery disease (CAD). The relative prognostic meaning of the SE result in hypertensive and normotensive patients remains to be addressed. Methods and results The study group was formed by 11… (More)
OBJECTIVE To make a prospective assessment of the clinical and prognostic correlates of angiographically diffuse non-obstructive coronary lesions. DESIGN Angiographic vessel and extent scores were calculated in 228 clinically stable patients (mean (SD) age, 60 (11) years; 43 women, 185 men) undergoing prospective follow up for the composite end point of… (More)
Stress cardiomyopathy (SCM) typically presents similar symptoms to acute myocardial infarction (AMI). However, these symptoms differ when it comes to a transient and completely reversible myocardial dysfunction, which is frequently precipitated by acute stressful events, occurring in the absence of plaque rupture and coronary thrombosis. The purpose of this… (More)
This review article summarizes the results of histopathological studies to assess heart failure in humans. Different histopathological features underlying the clinical manifestations of heart failure are reviewed. In addition, the present role of echocardiographic techniques in assessing the failing heart is briefly summarized.
This review article is aimed at comparing the results of histopathological and clinical imaging studies to assess coronary atherosclerotic plaques in humans. In particular, the gap between the two techniques and its effect on the understanding of the pathophysiological basis of coronary artery disease is critically discussed.
This review article summarizes the results of histopathological and clinical imaging studies to assess myocardial necrosis in humans. Different histopathological features of myocardial cell necrosis are reviewed. In addition, the present role of echocardiographic techniques in assessing irreversible myocardial damage is briefly summarized.
Secondary or functional mitral regurgitation (FMR) represents an increasing feature of mitral valve disease characterized by abnormal function of anatomically normal leaflets in the context of the impaired function of remodelled left ventricles. The anatomic and pathophysiological basis of FMR are briefly analyzed; in addition, the role of exercise… (More)
