BACKGROUND Low-dose dobutamine stress echocardiography is specific for predicting reversible contractility dysfunction, but its sensitivity is lower than ideal. OBJECTIVE We sought to explore the predictors of myocardial contractile recovery following revascularization, in patients with no viability by low-dose dobutamine stress echocardiography. METHODS We prospectively enrolled 30 consecu...
BACKGROUND This prospective non-randomized clinical study was done to compare Off-pump and On-pump myocardial revascularization by Troponin I release in patients undergoing first elective coronary artery bypass graft used to evaluate myocardial injury. METHODS One hundred an twenty patients were non-randomly assigned to a Off-pump or On-pump myocardial revascularization group. Cardiac Troponi...
OBJECTIVES To determine the relative degree of revascularization obtained with bypass surgery versus angioplasty in a randomized trial of patients with multivessel disease requiring revascularization (Bypass Angioplasty Revascularization Investigation [BARI]), one-year catheterization was performed in 15% of patients. BACKGROUND Complete revascularization has been correlated with improved out...
Providing anesthesia care for patients undergoing coronary artery bypass grafting (CABG) continues to be a challenging yet rewarding endeavor. Surgical, anesthetic, and technologic advances continue to drive changes in clinical routines at a rapid pace, even at a time when the numbers of cases have declined because of the growth of percutaneous coronary interventions (PCIs). Cardiac anesthesiol...
From 1969 to 1975, 175 patients with acute coronary insufficiency underwent emergency saphenous vein aorto-coronary bypass grafting (SVBG). The patients were divided into two groups: group I, unstable angina (165 patients) and group II, acute evolving myocardial infarction (ten patients). In group I, the hospital mortality was 8-4%, the incidence of post-operative myocardial infarction was 10-3...
authors and five references. They should not have tables or figures and should relate solely to an article published in Circulation within the preceding 12 weeks. Only some letters will be published. Authors of those selected for publication will receive prepublication proofs, and authors of the article cited in the letter will be invited to reply. Replies must be signed by all authors listed i...

tissue level myocardial perfusion is one of the most important prognostic factors after successful recanalisation of the occluded coronary artery in patients suffering acute st elevation myocardial infarction (stemi). the primary objective of the present study was to examine the relationship between videodensitometric myocardial perfusion parameters as assessed on coronary angiograms directly f...
We disagree with the comments made by Dr. F. James Brennan that major events were underreported in our recent Journal article (1). Although we used a composite end point that included death, myocardial infarction, cerebrovascular accident and myocardial revascularization, we also separately reported mortality, myocardial infarction, repeat revascularization procedures and stroke (1). For exampl...
Information on myocardial viability can be useful to decide when coronary artery revascularization is indicated for patients with acute myocardial infarction (AMI) and left regional or global ventricular dysfunction. Difficulties in assessing viability arise because the same part of the ventricular wall can have a mixture of necrotic tissue and viable myocardium. Diagnostic markers of myocardia...
