Comparison of Aortic Annulus Size by Transesophageal Echocardiography and Computed Tomography Angiography With Direct Surgical Measurement

Nov 30, 2016 by in CARDIOLOGY Comments Off on Comparison of Aortic Annulus Size by Transesophageal Echocardiography and Computed Tomography Angiography With Direct Surgical Measurement

This study sought to compare the accuracy of 2-dimensional transesophageal echocardiography (TEE) and computed tomography angiography (CTA) for noninvasive aortic annular sizing as required for transcatheter aortic valve implantation (TAVI)….

Effects of the Mueller Maneuver on Functional Mitral Regurgitation and Implications for Obstructive Sleep Apnea

Nov 30, 2016 by in CARDIOLOGY Comments Off on Effects of the Mueller Maneuver on Functional Mitral Regurgitation and Implications for Obstructive Sleep Apnea

Obstructive sleep apnea is prevalent and adversely affects cardiovascular health. However, little is known of the acute effects of an obstructive apnea on cardiovascular physiology. We hypothesized that pre-existing functional…

Usefulness of Cardiac Meta-Iodobenzylguanidine Imaging to Identify Patients With Chronic Heart Failure and Left Ventricular Ejection Fraction <35% at Low Risk for Sudden Cardiac Death

Nov 30, 2016 by in CARDIOLOGY Comments Off on Usefulness of Cardiac Meta-Iodobenzylguanidine Imaging to Identify Patients With Chronic Heart Failure and Left Ventricular Ejection Fraction <35% at Low Risk for Sudden Cardiac Death

Patients with chronic heart failure (CHF) at risk of sudden cardiac death (SCD) are often treated with implantable cardiac defibrillators (ICDs). However, current criteria for device use that is based…

Comparison of the Usefulness of Heart Rate Variability Versus Exercise Stress Testing for the Detection of Myocardial Ischemia in Patients Without Known Coronary Artery Disease

Nov 30, 2016 by in CARDIOLOGY Comments Off on Comparison of the Usefulness of Heart Rate Variability Versus Exercise Stress Testing for the Detection of Myocardial Ischemia in Patients Without Known Coronary Artery Disease

Heart rate variability (HRV) has been shown to be attenuated in patients with coronary artery disease (CAD) and may, therefore, be possibly used for the early detection of myocardial ischemia….

Prevalence and Outcomes of Patients Receiving Implantable Cardioverter-Defibrillators for Primary Prevention Not Based on Guidelines

Nov 30, 2016 by in CARDIOLOGY Comments Off on Prevalence and Outcomes of Patients Receiving Implantable Cardioverter-Defibrillators for Primary Prevention Not Based on Guidelines

Implantable cardioverter-defibrillator (ICD) implantation outside practice guidelines remains contentious, particularly during the mandated waiting periods in patients with recent cardiac events. We assessed the prevalence and outcomes of non–guideline-based (NGB)…

Frequency of Renal Artery Stenosis After Renal Denervation in Patients With Resistant Arterial Hypertension

Nov 30, 2016 by in CARDIOLOGY Comments Off on Frequency of Renal Artery Stenosis After Renal Denervation in Patients With Resistant Arterial Hypertension

Catheter-based ablation of nerves in the adventitia of renal arteries (renal artery denervation [RAD]) using radiofrequency energy can reduce blood pressure (BP) in patients with resistant arterial hypertension (RAH). Occurrence…

Antiplatelet and Statin Use in US Patients With Coronary Artery Disease Categorized by Race/Ethnicity and Gender, 2003 to 2012

Nov 30, 2016 by in CARDIOLOGY Comments Off on Antiplatelet and Statin Use in US Patients With Coronary Artery Disease Categorized by Race/Ethnicity and Gender, 2003 to 2012

Antiplatelets and statins are efficacious for preventing future cardiovascular events in patients with coronary heart disease. Disparity in cardiovascular outcomes exists by race/ethnicity and gender; however, few studies have explored…
