normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : supervised exercise-based cardiac rehabilitation programs (crp) have been suggested to all patients, especially after myocardial infarction. however, the effects of cardiac rehabilitation on systolic function are controversial. the aim of this study was to examine the effects of an 8-week cardiac rehabilitatio...
Introduction Left ventricular (LV) remodeling following myocardial infarction (MI) is the result of complex interactions between various factors, including presence or absence of early revascularization. Cardiovascular Magnetic Resonance (CMR) imaging with contrast-enhancement (CE) permits assessment of myocardial tissue and LV dimensions and function, but the impact of early revascularization ...
OBJECTIVE To assess the myocardial ischemic load to previous and after myocardial revascularization. METHODS Ninety-six randomized patients, carriers of multivessel coronary artery disease, stable angina, preserved left ventricular function, and exercise-induced myocardial ischemia treated with revascularization (SMR) or coronary angioplasty (TCA). Myocardial scintigraphy with 99mTc-Sestamibi...
Delayed improvement of left ventricular contractile function in the setting of acute ischemia followed by reperfusion ("stunned myocardium") has been observed in a number of clinical scenarios, and may have important clinical implications. At present, there are no widely accepted techniques available to demonstrate its presence. We report a case in which a rest 99mTc-sestamibi scan performed 12...
Some patients with severe angina have coronary artery disease which is unsuitable for conventional forms of revascularization — coronary angioplasty/ stenting or coronary artery bypass surgery. These patients have usually undergone previous revascularization procedures and have disease which is diffuse and affects the distal part of the coronary circulation. Transmyocardial laser revascularizat...
BACKGROUND Current guidelines suggest that coronary artery bypass grafting (CABG) should be the preferred revascularization method for unprotected left main coronary artery stenosis. In light of evidence from recent randomized trials, we assessed whether percutaneous coronary intervention (PCI) using drug-eluting stents is as safe and effective as CABG for the treatment of unprotected left main...
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 revi...
OBJECTIVE To evaluate the results of surgical revascularization in children with coronary artery lesions following neonatal arterial switch operation (ASO). METHODS Among 755 neonates who underwent ASO, there were 713 late survivors (94%). Coronary lesions were detected in 34 patients (5%). Coronary revascularization was carried out in 19 children (mean age: 5.6+/-3.2 years) in whom myocardia...
In patients with chronic ischaemic left ventricular dysfunction, revascularization may lead to symptomatic and prognostic improvement. Cardiovascular magnetic resonance (CMR) imaging with its high spatial resolution provides the qualitative and quantitative, global and regional information on myocardial anatomy and function. In combination with a gadolinium-based contrast agent, CMR allows an a...
BACKGROUND The objective of the present study was to compare the midterm follow-up results of percutaneous coronary intervention (PCI) and coronary bypass graft surgery (CABG) for the treatment of unprotected left main coronary artery disease in octogenarians. METHODS AND RESULTS A total of 249 consecutive patients > or =80 years of age diagnosed with left main coronary artery disease underwe...
