BACKGROUND The aim of our study was to evaluate the role of myocardial perfusion imaging (MPI) and common carotid artery intima-media thickness (CCA IMT) in the prognosis of patients with coronary artery disease referred for coronary artery bypass surgery (CABG) in a newly made prognostic model. MATERIAL AND METHODS 63 patients (age 60.36 +/- 8.28 years) with angiographically established coro...

Assessment of myocardial viability 1>rior to revascularization procedures is an important clinical consideration for improved functional recovery of regional left ventricular dysfunction. In chronic coronary artery disease, impaired left ventricular function , at least in part, is due to ischemic or hibernating myocardium rather than just myocardial fibrosis. Functional recovery of the left ven...

OBJECTIVES This study pools data from published series examining late survival with revascularization versus medical therapy after myocardial viability testing in patients with severe coronary artery disease (CAD) and left ventricular (LV) dysfunction. BACKGROUND Previous observational studies have suggested survival benefit in such patients if they are revascularized when myocardial viability ...

OBJECTIVES We sought to evaluate the usefulness of a comprehensive assessment of four cardiovascular magnetic resonance imaging (CMR)-derived myocardial viability indexes in the setting of myocardial stunning. BACKGROUND Cardiovascular magnetic resonance imaging allows the simultaneous assessment of several viability indexes. METHODS We studied 40 patients with a first ST-segment elevation ...

Purpose: To assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in Cardiac Magnetic Resonance of patients with history of remote myocardial infarction. Materials and Methods: The Cardiac Magnetic Resonance images of sixty patients with history of remote ST segment or non-ST segment elevation myocardial infarction were ...

Over the past decade it has become clear that chronic left ventricular dysfunction is not necessarily an irreversible process[1-41. In some patients recovery of function may occur dependent on the presence of dyssynergic yet viable myocardium. It has been hypothesized that chronic hypoperfusion may result in a down-regulation of myocardial contractility and this process can be reversed after ad...

Background The efficacy of current and novel heart failure therapies is likely related to viability that denotes the presence of cardiac reserve. Previous studies assessed viability mostly on a segmental rather than patient level, and included hypokinetic segments, which by definition−given residual contractile function−are viable. Additionally, studies have suggested that long-term survival is...

OBJECTIVES This study sought to determine whether residual myocardial viability determined by myocardial contrast echocardiography (MCE) after acute myocardial infarction (AMI) can predict hard cardiac events. BACKGROUND Myocardial viability detected by MCE has been shown to predict recovery of left ventricular (LV) function in patients with AMI. However, to date no study has shown its value ...
