We compare the diagnostic accuracy of multidetector row computed tomography (MDCT) to cardiac magnetic resonance imaging (CMR) for evaluating global left ventricular function. We systematically searched PubMed, CINAHL, Cochrane CENTRAL, Scopus, and the Web of Science databases for studies published between 1966 to January 2013 that compared left ventricle(More)
OBJECTIVE To clarify whether any particular β blocker is superior in patients with heart failure and reduced ejection fraction or whether the benefits of these agents are mainly due to a class effect. DESIGN Systematic review and network meta-analysis of efficacy of different β blockers in heart failure. DATA SOURCES CINAHL(1982-2011), Cochrane(More)
BACKGROUND Thrombosis is a pivotal event in the pathogenesis of coronary disease. We hypothesized that the presence of blood factors that reflect enhanced thrombogenic activity would be associated with an increased risk of recurrent coronary events during long-term follow-up of patients who have recovered from myocardial infarction. METHODS AND RESULTS We(More)
We have observed an electrocardiographic (ECG) pattern of deep T-wave or "giant T wave" inversion in patients with acute coronary insufficiency. We reviewed the ECGs of 936 patients admitted to our coronary care unit during a one-year period. We found the pattern of giant T-wave inversion was present in nine patients (1 percent). We examined the(More)
BACKGROUND In patients with atrial fibrillation (AF), ventricular rate control with medications has been found to be noninferior in preventing clinical events, compared to a strategy converting patients to sinus rhythm and maintaining it with medications. Guidelines have accepted rate control as an acceptable therapeutic option. Most of the prior studies(More)
BACKGROUND This study aimed to determine whether QRS morphology identifies patients who benefit from cardiac resynchronization therapy with a defibrillator (CRT-D) and whether it influences the risk of primary and secondary end points in patients enrolled in the Multicenter Automatic Defibrillator Implantation Trial-Cardiac Resynchronization Therapy(More)
PURPOSE Patients with Atrial Fibrillation (AF) and prior stroke are classified as high risk in all risk stratification schemes. A systematic review and meta-analysis was performed to compare the efficacy and safety of New Oral Anticoagulants (NOACs) to warfarin in patients with AF and previous stroke or transient ischemic attack (TIA). METHODS Three(More)
BACKGROUND The benefit of blood transfusion in patients with myocardial infarction is controversial, and a possibility of harm exists. METHODS A systematic search of studies published between January 1, 1966, and March 31, 2012, was conducted using MEDLINE, EMBASE, CINAHL, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials(More)
The management of patients with acute myocardial infarction complicated by bundle branch block is a significant clinical problem and represents 8% to 13% of patients with acute infarction. This study reviews the records of 606 patients with myocardial infarction admitted to our coronary care unit. Forty-seven (8%) had complete bundle branch block. The risk(More)
