OBJECTIVES: The goal of this study was to use machine learning to more accurately predict survival after echocardiography. BACKGROUND: Predicting patient outcomes (e.g., survival) following echocardiography is primarily based on ejection fraction (EF) and comorbidities. However, there may be significant predictive information within additional echocardiography-derived measurements combined with clinical electronic health record data. METHODS: Mortality was studied in 171,510 unselected patients who underwent 331,317 echocardiograms in a large regional health system...

OBJECTIVES: This study sought to compare the per-patient diagnostic performance of coronary computed tomography angiography (CTA)-derived fractional flow reserve (FFRCT ) with that of single-photon emission computed tomography (SPECT), using a fractional flow reserve (FFR) value of ≤0.80 as the reference for diagnosing at least 1 hemodynamically significant stenosis in a head-to-head comparison of patients with intermediate coronary stenosis as determined by coronary CTA. BACKGROUND: No previous study has prospectively compared the diagnostic performance of FFRCT and myocardial perfusion imaging by SPECT in symptomatic patients with intermediate range coronary artery disease (CAD)...

OBJECTIVES: The study evaluated whether lipoprotein apheresis produces immediate changes in resting perfusion in subjects with severe hypercholesterolemia, and whether there is a difference in the response between peripheral and coronary microcirculations. BACKGROUND: Lipoprotein apheresis is used in patients with severe hypercholesterolemia to reduce plasma levels of low-density lipoprotein cholesterol. METHODS: Quantitative contrast-enhanced ultrasound perfusion imaging of the myocardium at rest and skeletal muscle at rest and during calibrated contractile exercise was performed before and immediately after lipoprotein apheresis in 8 subjects with severe hypercholesterolemia, 7 of whom had a diagnosis of familial hypercholesterolemia...

OBJECTIVES: This study sought to compare early emergency department (ED) use of coronary computed tomography angiography (CTA) and stress echocardiography (SE) head-to-head. BACKGROUND: Coronary CTA has been promoted as the early ED chest pain triage imaging method of choice, whereas SE is often overlooked in this setting and involves no ionizing radiation. METHODS: The authors randomized 400 consecutive low- to intermediate-risk ED acute chest pain patients without known coronary artery disease and a negative initial serum troponin level to immediate coronary CTA (n = 201) or SE (n = 199)...

OBJECTIVES: This study aims to establish parameters for identifying normal function for each of the 3 iterations of balloon-expandable valves and 2 iterations of self-expanding valves. BACKGROUND: Expected transthoracic echocardiographic Doppler-derived hemodynamic data for transcatheter aortic valves inform pre-implant decision-making and post-implanted monitoring of longitudinal valve function. METHODS: We collected the Echocardiography Core Lab measured mean gradients and effective orifice area (EOA) from discharge or 30-day echocardiograms from randomized trials; the PARTNER (Placement of Aortic Transcatheter Valves) trials for the balloon-expandable valves and the Medtronic CoreValve US Pivotal trial and Medtronic CoreValve Evolut R United States IDE Clinical Study for the self-expanding valves...

OBJECTIVES: This study sought to describe the impact of statins on individual coronary atherosclerotic plaques. BACKGROUND: Although statins reduce the risk of major adverse cardiovascular events, their long-term effects on coronary atherosclerosis remain unclear. METHODS: We performed a prospective, multinational study consisting of a registry of consecutive patients without history of coronary artery disease who underwent serial coronary computed tomography angiography at an interscan interval of ≥2 years...

OBJECTIVES: The aim of this study was to study differences in progression of aortic stenosis (AS) in patients with mediastinal radiotherapy (XRT)-associated moderate AS versus a matched cohort during the same time frame, and to ascertain need for aortic valve replacement (AVR) and longer-term survival. BACKGROUND: Rate of progression of XRT-associated moderate AS and its impact on outcomes is not well-described. METHODS: We included 81 patients (age 61 ± 13 years; 57% female) with at least XRT-associated moderate AS (aortic valve area [AVA] 1...

OBJECTIVES: The authors aimed to analyze temporal trends in cardiac stress testing in U.S. Medicare beneficiaries from 2008 to 2012, types of stress testing, and comparative utilization related to the presence and severity of chronic kidney disease (CKD). BACKGROUND: A long-held perception depicts patients with CKD as being treated less intensively for cardiovascular disease than nonrenal patients. We wondered whether use of diagnostic testing for ischemic heart disease is affected by the presence of CKD...

OBJECTIVES: This study sought to evaluate the hypothesis that global longitudinal strain (GLS) guidance of cardioprotective therapy would improve cardiac function of at-risk patients undergoing potentially cardiotoxic chemotherapy, compared with usual care. BACKGROUND: The conventional criteria for diagnosis of chemotherapy-related cardiac dysfunction (CTRCD) are dependent on the recognition of heart failure symptoms and/or changes in left ventricular ejection fraction...
