OBJECTIVES The aim of the study was to compare head-to-head the performance of exercise tolerance test-stress echocardiography (ex-Echo) and exercise stress-perfusion nuclear imaging (exercise-single-photon emission computed tomography [ex-SPECT]) for the diagnosis of coronary artery disease (CAD) in patients evaluated at the chest pain unit with delay from(More)
Chest pain (CP) represents a frequent reason for presentation at the emergency department (ED). A large proportion of patients have non-diagnostic ECG on presentation, and in many cases several hours have elapsed since onset of symptoms. Acute rest myocardial scintigraphy (rest SPET) has been shown to have a relevant role in the detection of patients at(More)
We selected 73 consecutive patients without myocardial-infarction, hypertrophic cardiomyopathy or hypertension complaining of effort chest discomfort/dyspnoea, and/or reporting exercise ischaemic ECG changes, and submitted them to simultaneous dobutamine stress echocardiography (DSE) and 99mTc tetrofosmin SPECT (T SPECT) and to coronary angiography to(More)
The study aim was to assess whether post-ejection thickening (PT) is an useful marker of viable myocardium in patients with chronic coronary artery disease. Twenty-three patients with critical coronary stenoses were submitted to dobutamine and dipyridamole stress-echocardiographies and dipyridamole-early-redistribution 201TI SPECT within 15 days from(More)
OBJECTIVES AND BACKGROUND Dobutamine stress echocardiography and 99mTc-tetrofosmin single-photon emission computed tomography (T-SPECT) were performed simultaneously in subjects in whom coronary artery disease (CAD) had been proven or excluded at coronary angiography, in order to establish their accuracy and agreement in the diagnosis of CAD, and in(More)
BACKGROUND Patients with chest pain (CP) and nondiagnostic ECG represent heterogeneous population in whom the evaluation of coronary risk factors including metabolic syndrome (MetS) and diabetes mellitus (DM) might improve risk stratification. METHODS We enrolled 798 consecutive CP patients; 14% presented with MetS and 10% with DM; the remaining 76%(More)
BACKGROUND AND AIM Either 99mTechnetium diphosphonate (Tc-DPD) or pyrophosphate (Tc-PYP) scintigraphy plays a relevant role in diagnosing transthyretin cardiac amyloidosis (CA), and labeled radiotracers have been extensively studied in diagnosing CA. Few studies have analyzed and validated 99mTc-Hydroxymethylene diphosphonate (Tc-HMDP). Our aim was to(More)
The risk of overlooking an underlying acute coronary syndrome remains an important challenge in patients complaining of chest pain but who have a non-diagnostic ECG (CP). Indeed, myocardial scintigraphy associated with exercise testing (exercise SPET) represents a valuable tool for excluding coronary artery disease (CAD) especially in patients with CP and(More)
Whether physical training, soon after myocardial infarction (MI), has effects upon intrinsic cardiac function at rest and during exertion remains unresolved. We have evaluated ventricular function using radionuclide angiography at rest and during stress testing before and after 3 months' physical training. This has been correlated with the site of MI and(More)
OBJECTIVE To update the prognostic value of scan strategy with pharmacological stress agent in chest pain (CP) patients presenting with normal electrocardiography (ECG) and troponin. METHODS Two consecutive nonrandomized series of patients with CP and negative first-line workup inclusive of serial ECG, serial troponin, and echocardiography underwent(More)
