BACKGROUND: In patients with acute coronary syndrome (ACS), reduced left ventricular ejection fraction (LVEF) is a known marker for increased mortality. However, the relationship between LVEF measured during index ACS hospitalization and mortality and heart failure (HF) within 1 year are less well-defined. METHODS: We performed a retrospective analysis of 445 participants in the IMMEDIATE Trial who had LVEF measured by left ventriculography or echocardiogram during hospitalization...

BACKGROUND: In this study, we investigate the correlation between reduced global longitudinal peak systolic strain (GLPSS) and the SYNTAX score (SS) in patients undergoing coronary angiography. METHODS: We examined 71 patients undergoing both echocardiogram and coronary angiography within 15 days. All patients had normal global and/or regional wall motion on resting echocardiogram. We calculated GLPSS using two-dimensional speckle-tracking echocardiography. SS was calculated for each group of patients based on the presence and/or the severity of coronary artery disease (CAD): no CAD on angiogram (n=10, control group), low SS (n=36, SS<22) and high SS (n=25, SS≥22)...

BACKGROUND AND PURPOSE: Atherosclerosis is a systemic disease, and both coronary and intracranial atherosclerosis are common in the elderly. Unlike coronary artery disease (CAD), intracranial atherosclerotic disease can cause intracranial atherosclerotic stroke by branch occlusive disease (B-type) and coronary-type rupture of plaque (C-type). We hypothesized that plaque characteristics of intracranial arteries are associated with those of coronary arteries. METHODS: Eighty-one patients with acute cerebral infarcts caused by intracranial atherosclerotic disease without history of CAD were analyzed...

OBJECTIVES: Coronary computerized tomography angiography (CCTA) is a rapidly emerging technology for the evaluation of chest pain in the emergency department (ED). We assessed trends in CCTA use and compared downstream healthcare utilization between CCTA and cardiac stress testing modalities. METHODS: Using administrative claims data (Optum Labs Data Warehouse) from over 100 million geographically diverse privately insured and Medicare Advantage enrollees across the United States, we identified 2,047,799 ED patients from January 2006 to December 2013 who presented with chest pain and had a CCTA or cardiac stress test within 72 hours...

BACKGROUND: The Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial found that initial use of ≥64 detector-row computed tomography angiography versus standard functional testing strategies (exercise ECG, stress nuclear methods, or stress echocardiography) did not improve clinical outcomes in 10 003 stable symptomatic patients with suspected coronary artery disease requiring noninvasive testing. Symptom burden and quality of life (QOL) were major secondary outcomes...

AIMS: Exercise electrocardiography (ExECG) is widely used in suspected stable angina (SA) as the initial test for the evaluation of coronary artery disease (CAD). We hypothesized that exercise stress echo (ESE) would be efficacious with cost advantage over ExECG when utilized as the initial test. METHODS AND RESULTS: Consecutive patients with suspected SA, without known CAD were randomized into ExECG or ESE. Patients with positive tests were offered coronary angiography (CA) and with inconclusive tests were referred for further investigations...

We present the case of an asymptomatic 82-year-old patient with no coronary artery disease and a negative cardiac workup who presented to the hospital for an elective total knee replacement. The patient had stable vital signs in the preanesthesia holding unit, yet the anesthesiologist recognized new-onset atrial fibrillation on the patient's monitor. The dysrhythmia was confirmed with a 12-lead electrocardiogram. The procedure was canceled, and the patient was sent for additional evaluation. An echocardiogram revealed a pulmonary embolism...

AIMS: Blood pressure (BP) responses during dobutamine stress echocardiography (DSE) have not been systematically studied. Consequently, it is not known what constitutes a normal or an abnormal BP response to dobutamine stress. We sought to define the typical BP response during DSE of patients not known to have cardiovascular disease. METHODS AND RESULTS: Of 24 134 patients who underwent DSE from November 2003 to December 2012 at Mayo Clinic, Rochester, MN, 2968 were selected for inclusion in this retrospective study...

Availability of hydroxyurea (HU) coupled with early therapeutic interventions has increased the life expectancy of patients with sickle cell disease. Hence, the sickle cell community needs to be aware of common diseases of aging that survivors are predisposed to. We chose to investigate the sickle cell disease-related complications as well as non sickle cell disease-related medical problems of aging in 45 sickle cell patients over the age of 40 years. The most frequent chronic complications of sickle cell disease were elevated tricuspid regurgitant jet velocity on echocardiogram, chronic renal disease, iron overload and leg ulcers...
