Background

The REHAB‐HF (Rehabilitation Therapy in Older Acute Heart Failure Patients) randomized trial demonstrated that a 3‐month transitional, tailored, progressive, multidomain physical rehabilitation intervention improves physical function, frailty, depression, and health‐related quality of life among older adults with acute decompensated heart failure. Whether there is differential intervention efficacy by race is unknown.

Methods and Results

In this prespecified analysis, differential intervention effects by race were explored at 3 months for physical function (Short Physical Performance Battery [primary outcome], 6‐Minute Walk Distance), cognition, depression, frailty, health‐related quality of life (Kansas City Cardiomyopathy Questionnaire, EuroQoL 5‐Dimension‐5‐Level Questionnaire) and at 6 months for …

Glycogen storage disease cardiomyopathy is being recognized increasingly as a mimicker of hypertrophic cardiomyopathy. It is important to diagnose these diseases, as there are prognostic and treatment ramifications. This case report discusses a patient who presented with cardioembolic renal infarction and was ultimately diagnosed with glycogen storage disease XV (which is extremely rare). The diagnosis was made by pursuing multimodality imaging, endomyocardial biopsy, and genetic testing.

Utilization And Short-Term Outcomes Of Percutaneous Left Atrial Appendage Occlusion In Patients With Cancer, Yaqi Zhang, Zhuoran Yang, Muhammad Usman Almani, Raquel Soon-Shiong, Bolun Liu

Einstein Health Papers

Background

Percutaneous left atrial appendage occlusion (LAAO) has been rapidly evolving since FDA’s approval in 2015 and has become more of a same-day-discharge procedure. Cancer patient with atrial fibrillation/flutter (AF) population can benefit from the procedure but the in-hospital outcomes and readmission data were rarely studied.

Objectives

We investigated the utilization, in-hospital and readmission outcomes in cancer patients with AF who underwent LAAO.

Methods

Data were derived from the National Inpatient Sample and National Readmissions Database from 2016 to 2019. Patients with primary diagnosis of AF admitted for LAAO (ICD-10 code 02L73DK) were grouped by cancer as a secondary diagnosis. …

Supraventricular Tachycardia Associated With Repeat Cesarean Section Under Spinal Anesthesia., Mihir Patel, Matthias Franzen, Camille D Hawkins, Matthew Brown, Samir Patel

Heart and Vascular Articles

Supraventricular tachycardia (SVT) is the most common tachyarrhythmia of pregnancy. Catecholamine surges, the use of vasoactive agents during delivery, and increased cardiac output during pregnancy are the most common contributing factors to developing SVT. SVT is usually benign in presentation but can lead to more serious arrhythmias in patients with a history of mitral stenosis secondary to rheumatic heart disease. When an SVT is detected, organic heart causes should be ruled out first. Symptoms of SVT include shortness of breath, palpitations, syncope, sweating, chest pain, and dizziness. In patients who are refractory to pharmacologic management and hemodynamically unstable, electrical cardioversion …

Α-Synuclein Is The Major Platelet Isoform But Is Dispensable For Activation, Secretion, And Thrombosis, Alexis N. Smith, Smita Joshi, Harry Chanzu, Hammodah Rawhi Hammodah Alfar, Kanakanagavalli Shravani Prakhya, Sidney W. Whiteheart

Saha Cardiovascular Research Center Faculty Publications

Platelets play many roles in the vasculature ensuring proper hemostasis and maintaining integrity. These roles are facilitated, in part, by cargo molecules released from platelet granules via Soluble NSF Attachment Protein Receptor (SNARE) mediated membrane fusion, which is controlled by several protein-protein interactions. Chaperones have been characterized for t-SNAREs (i.e. Munc18b for Syntaxin-11), but none have been clearly identified for v-SNAREs. α- Synuclein has been proposed as a v-SNARE chaperone which may affect SNARE-complex assembly, fusion pore opening, and thus secretion. Despite its abundance and that it is the only isoform present, α-synuclein’s role in platelet secretion is uncharacterized. In …

Atrial Shunt Therapy For Heart Failure: An Update, William Gray

Department of Medicine Faculty Papers

Transcatheter atrial shunt therapies, designed to dynamically lower left atrial (LA) pressure by shunting blood into the larger reservoir of the right atrium and central veins, have been developed as a novel treatment for heart failure (HF) over the past 10+ years. Several atrial shunt devices and procedures are currently in development with several pivotal randomized clinical trials (RCT) underway; however, only 2 sham-controlled RCT (both with the Atrial Shunt Device [Corvia Medical] in HF with EF ≥ 40%) have been reported thus far; a mechanistic RCT (n = 44) that demonstrated a reduction in exercise LA pressure at …

Cardiac muscle has the highest mitochondrial density of any human tissue, but mitochondrial dysfunction is not a recognized cause of isolated cardiomyopathy. Here, we determined that the rare mitofusin (MFN) 2 R400Q mutation is 15-20× over-represented in clinical cardiomyopathy, whereas this specific mutation is not reported as a cause of MFN2 mutant-induced peripheral neuropathy, Charcot-Marie-Tooth disease type 2A (CMT2A). Accordingly, we interrogated the enzymatic, biophysical, and functional characteristics of MFN2 Q400 versus wild-type and CMT2A-causing MFN2 mutants. All MFN2 mutants had impaired mitochondrial fusion, the canonical MFN2 function. Compared to MFN2 T105M that lacked catalytic GTPase activity and exhibited normal …

Aortic Arch Reconstruction Using Nonvalved Femoral Vein Homograft In High-Risk Neonates, Kyle G Mitchell, Julija Dobrila, Blaz Podgorsek, Christopher Greenleaf, Peter Chen, Jorge D Salazar, Damien J Lapar

Faculty, Staff and Student Publications

Aortic arch obstruction is often present with complex concomitant congenital heart defects (CHDs). The use of nonvalved femoral vein homograft (FVH) to reconstruct the aortic arch has distinct surgical advantages, including simplified reconstruction. We present an intraoperative video of a Yasui procedure utilizing FVH for aortic reconstruction in a 12-day-old (2.2 kg) neonate with right ventricular outflow tract obstruction, malalignment ventricular septal defect, aortic valve atresia, aortic arch hypoplasia, atrial septal defect, and ductal dependent systemic circulation. Further, we report outcomes for a series of three additional neonatal patients with complex CHD and aortic arch obstruction who underwent FVH arch …

Objective: Stenting of renal and mesenteric vessels may result in changes in velocity measurements due to arterial compliance, potentially giving rise to confusion about the presence of stenosis during follow-up. The aim of our study was to compare preoperative and postoperative changes in peak systolic velocity (PSV, cm/s) after placement of the celiac axis (CA), superior mesenteric artery (SMA) and renal artery (RAs) bridging stent grafts during fenestrated-branched endovascular aortic repair (FB-EVAR) for treatment of complex abdominal aortic aneurysms (AAA) and thoracoabdominal aortic aneurysms.

Methods: Patients were enrolled in a prospective, nonrandomized single-center study to evaluate FB-EVAR for treatment of …

Interplay Of Hypoxia-Inducible Factors And Oxygen Therapy In Cardiovascular Medicine, Yafen Liang, Wei Ruan, Yandong Jiang, Richard Smalling, Xiaoyi Yuan, Holger K Eltzschig

Faculty, Staff and Student Publications

Mammals have evolved to adapt to differences in oxygen availability. Although systemic oxygen homeostasis relies on respiratory and circulatory responses, cellular adaptation to hypoxia involves the transcription factor hypoxia-inducible factor (HIF). Given that many cardiovascular diseases involve some degree of systemic or local tissue hypoxia, oxygen therapy has been used liberally over many decades for the treatment of cardiovascular disorders. However, preclinical research has revealed the detrimental effects of excessive use of oxygen therapy, including the generation of toxic oxygen radicals or attenuation of endogenous protection by HIFs. In addition, investigators in clinical trials conducted in the past decade have …

While specific questionnaires for severe ischemia are lacking, the SF-36 questionnaire is widely used to assess quality of life, with variations like SF-12 and SF-8 for larger cohorts. Objectives. Our aim was to assess how different lower limb revascularization methods affect the postoperative quality of life in patients with chronic limb-threatening ischemia. Methods. This study was conducted at the St. Pantelimon Emergency Hospital of Bucharest, Romania. It included 166 adult patients with …

Coronary Artery Calcium Scoring In Asymptomatic Patients, Bilal Hussain, Ahmed Mahmood, Michael G. Flynn, Thomas Alexander

HCA Healthcare Journal of Medicine

Coronary artery calcium (CAC) scoring is an important prognostic tool for personalized cardiovascular preventive care and has recently been incorporated into American College of Cardiology/American Heart Association guidelines. CAC provides direct visualization and quantification of CAC burden for risk stratification and primary prevention of cardiovascular events in an asymptomatic population. CAC scoring is recommended for individuals with intermediate 10-year atherosclerotic cardiovascular disease (ASCVD) risk and selective populations with borderline ASCVD risk. In this review, we outline the interpretation of CAC scores for predicting the risk of cardiovascular events, and we highlight the guidelines for starting statin and potentially starting aspirin …
