Comparison of Candesartan and Angiotensin-(1-7) Combination and Mito Tempo Treatment for Normalizing Blood Pressure and Sympathovagal Balance in (Mren2)27 Rats.

J Cardiovasc Pharmacol 2018 Dec 10. Epub 2018 Dec 10.

Hypertension & Vascular Research, Cardiovascular Sciences Center, Wake Forest University School of Medicine, Medical Center Boulevard, Winston-Salem, NC 27157.

Hypertensive transgenic (mRen2)27 rats exhibit impaired baroreflex sensitivity (BRS) for control of heart rate (HR). Intracerebroventricular (ICV) infusion of Ang-(1-7) improves indices of vagal BRS independent of lowering mean arterial pressure (MAP), while AT1 receptor blockade normalizes MAP and indices of sympathetic tone without correcting the vagal BRS. Scavenging cellular reactive oxygen species (ROS) with tempol in brain fails to correct either hypertension or sympathovagal balance in these animals, despite reports that mitochondrial ROS contributes to Ang II-infusion hypertension.

Assessment and management of coronary artery disease in kidney and pancreas transplant candidates.

J Cardiovasc Med (Hagerstown) 2018 Dec 11. Epub 2018 Dec 11.

Department of Medicine, Bluhm Cardiovascular Institute, Northwestern University Feinberg School of Medicine, Chicago, Illinois.

: Patients with end-stage renal disease (ESRD) undergoing evaluation for kidney and/or pancreas transplantation represent a population with unique cardiovascular (CV) profiles and unique therapeutic needs. Coronary artery disease (CAD) is common in patients with ESRD, mediated by both the overrepresentation and higher prognostic value of traditional CV risk factors amongst this population, as well as altered cardiovascular responses to failing renal function, likely mediated by dysregulation of the renin-angiotensin-aldosterone system (RAAS) and abnormal calcium and phosphate metabolism. Within the ESRD population, obstructive CAD correlates highly with adverse coronary events, including during the peri-transplant period, and successful revascularization may attenuate some of that increased risk.

Cardiac magnetic resonance T1 mapping. Part 2: Diagnostic potential and applications.

Eur J Radiol 2018 Dec 21;109:235-247. Epub 2018 Oct 21.

Division of General Radiology, Department of Radiology, Medical University of Graz, Auenbruggerplatz 19/P, 8036 Graz, Austria; Research & Development, Siemens Healthcare Diagnostics GmbH, Strassgangerstrasse 315, 8054 Graz, Austria. Electronic address:

Non-invasive identification and differentiation of myocardial diseases represents the primary objectives of cardiac magnetic resonance (CMR) longitudinal relaxation time (T1) and extracellular volume (ECV) mapping. Given the fact that myocardial T1 and ECV values overlap throughout and within left ventricular phenotypes, a central issue to be addressed is whether and to what extent myocardial T1 and ECV mapping provides additional or superior diagnostic information to standard CMR imaging, and whether native T1 mapping could be employed as a non-contrast alternative to late gadolinium enhancement (LE) imaging. The present review aims to summarize physiological and pathophysiological alterations in native T1 and ECV values and summarized myocardial T1 and ECV alterations associated with cardiac diseases to support the translation of research findings into routine CMR imaging.
