BACKGROUND The Revised Cardiac Risk Index (RCRI) is useful for risk stratifying patients before noncardiac operations. Among patients with documented coronary artery disease who undergo vascular surgery, it is unclear whether preoperative revascularization reduces postoperative cardiac complications in high-risk subsets defined by the RCRI. METHODS AND RESULTS The Coronary Artery Revasculariz...
PURPOSE The benefits of prophylactic coronary revascularization for patients undergoing noncardiac surgery are uncertain. The purpose of this study was to systematically evaluate the effect of coronary revascularization and medical management on short- and long-term outcomes after noncardiac surgery. METHOD Ten electronic databases including MEDLINE and EMBASE (1980 to February 2006), and bib...
BACKGROUND The presence of persistent myocardial uptake of 18F-deoxyglucose (FDG) within hypoperfused, dysfunctional segments has been shown to predict the recovery of regional contractile function after revascularization. The spectrum of metabolic responses of such hibernating tissue to revascularization is less clear. METHODS AND RESULTS Sixteen patients with previous infarction were studie...
BACKGROUND The aim of this study was to assess the incremental prognostic value of stress technetium 99m tetrofosmin imaging after myocardial revascularization. METHODS AND RESULTS We studied 381 patients (aged 60 +/- 10 years, 270 men), 4.5 +/- 3.2 years after myocardial revascularization (coronary artery bypass grafting in 201 patients and percutaneous coronary intervention in 180 patients)...
OBJECTIVES The objective of this study was to analyze the influence of coronary artery revascularization in patients with ventricular arrhythmias. BACKGROUND Coronary artery revascularization is an effective treatment for myocardial ischemia; however, its effect on ventricular arrhythmias not related to an acute ischemic event has not been carefully studied. METHODS Sixty-four patients (58 ...
background: the optimal strategy in percutaneous coronary intervention (pci) for coronary artery bifurcation lesions has yet to be agreed upon. we compared a strategy for stenting the main vessel to provide a complete perfusion flow in the side branch, namely thrombolysis in myocardial infarction (timi) - iii, with a strategy for intervention in both the main vessel and the side branch (mv + sb...
conclusions mortality from papillary muscle rupture remains elevated. survival largely depends on the early surgical repair or the replacement of the mitral valve. case presentation a 71-year-old woman presented to an outside hospital complaining of chest pain and shortness of breath. an electrocardiogram was obtained and revealed depression of the st segments from leads v1 to v4. troponin i wa...
