OBJECTIVE To assess the prognostic value of Technetium-99m-labeled single-photon emission computerized tomography (SPECT) in the follow-up of patients who had undergone their first myocardial revascularization. METHODS We carried out a retrospective study of 280 revascularized patients undergoing myocardial scintigraphy under stress (exercise or pharmacological stress with dipyridamole) and a...
Rev Esp Cardiol 2003;56(3):303-13 303 In recent years, the characteristics of patients who suffer acute myocardial infarction without complications during hospitalization have changed. In addition, the range of non-invasive studies available for evaluating left ventricular systolic function, residual myocardial ischemia, and myocardial viability in these patients has improved. Left ventricular ...
Left ventricular dysfunction is a powerful prognostic predictor in patients with coronary artery disease and increasing number of patients with CAD and ischemic left ventricular (LV) dysfunction is a major clinical problem. Congestive heart failure is a frequent complication which is associated with significant health care costs and two-third of cases have ischemic cardiomyopathy. In such patie...
BACKGROUND/AIMS Although complex bifurcation stenting in patients with non-left main (LM) bifurcation lesions has not yielded better clinical outcomes than simpler procedures, the utility of complex bifurcation stenting to treat LM bifurcation lesions has not yet been adequately explored. METHODS In the present study, patients who underwent LM-to-left anterior descending (LAD) coronary artery...
The effects of halothane on myocardial blood flow and myocardial oxygen balance were studied in seven male patients with stable angina and normal left ventricular function. Patients were receiving maintenance doses of beta-receptor antagonists and underwent coronary artery bypass surgery. Anaesthesia consisted of halothane and 50% nitrous oxide in oxygen. Halothane decreased myocardial blood fl...
BACKGROUND Imaging of myocardial glucose metabolism using [18F]fluorodeoxyglucose (FDG) with positron emission tomography (PET) has been proposed for identification of tissue viability in patients with advanced coronary artery disease. This study was designed to evaluate the predictive value of flow and metabolic imaging for functional recovery after revascularization in myocardial segments of ...
BACKGROUND The impact of percutaneous coronary intervention (PCI) on chronic total occlusion in patients with well-developed collaterals is not clear. METHODS AND RESULTS A total of 640 chronic total occlusion patients with collateral flow grade ≥2 were divided into 2 groups; chronic total occlusion patients either treated with PCI (the PCI group; n=305) or optimal medical therapy (the optima...
UNLABELLED This study analyzed the incidence and clinical significance of reverse redistribution (RR) on stress-redistribution (201)Tl SPECT studies in patients with poor left ventricular function and tested the hypothesis that the RR phenomenon could be caused by artifacts. METHODS Seventy-three consecutive patients with chronic coronary artery disease and left ventricular dysfunction (eject...
Coronary subclavian steal syndrome is a rare ischemic cause in patients after myocardial revascularization surgery. Subclavian artery stenosis or compression proximal to the internal mammary artery graft is the underlying cause. The authors present a clinical case of a patient with previous history of non-ST elevation myocardial infarction, triple coronary bypass, and effort angina since the su...
