Objective: Bypass surgery remains the revascularization strategy of choice for left main trunk coronary artery disease in an unselected group of patients. Drug eluting stents have been proposed as a viable alternative to bypass surgery for left main trunk lesions but their intermediate and long term outcomes are still under scrutiny.
Methods: A series of 50 patients with significant unprotected left main trunk stenosis (>50%) underwent revascularization with drug eluting stents (sirolimus and paclitaxel stents) and were enrolled in a registry.
Hypothesis: The aim of the study was to determine the utility of stress echocardiography for identification of significant coronary artery disease (CAD) in higher-risk patients with an underlying left bundle-branch block (LBBB).
Methods: Patients with LBBB undergoing stress echocardiography were divided into 2 groups: group 1 (no history MI), group 2 (history MI). Positive stress echocardiograms were compared with the presence of >50% luminal-diameter stenosis during coronary angiography.
Background: A number of innovative approaches have been investigated for their value in the early detection of acute ischemia or infarction in patients presenting to the emergency department (ED) with chest pain suggestive of a cardiac origin. Prior investigations have demonstrated the utility of adding right precordial and posterior chest leads to the standard 12-lead electrocardiogram (ECG) for identifying right ventricular and posterior wall infarctions in the ED.
Hypothesis: To assess the utility of additional ECG leads in low-risk patients presenting to the ED with symptoms suggestive of acute coronary syndromes who are managed in a chest pain evaluation unit (CPEU).
