Developing A Parsimonious Frailty Index For Older, Multimorbid Adults With Heart Failure Using Machine Learning, Javad Razjouyan, Molly J Horstman, Ariela R Orkaby, Salim S Virani, Orna Intrator, Parag Goyal, Christopher I Amos, Aanand D Naik

Faculty, Staff and Student Publications

Frailty is associated with adverse outcomes in heart failure (HF). A parsimonious frailty index (FI) that predicts outcomes of older, multimorbid patients with HF could be a useful resource for clinicians. A retrospective study of veterans hospitalized from October 2015 to October 2018 with HF, aged ≥50 years, and discharged home developed a 10-item parsimonious FI using machine learning from diagnostic codes, laboratory results, vital signs, and ejection fraction (EF) from outpatient encounters. An unsupervised clustering technique identified 5 FI strata: severely frail, moderately frail, mildly frail, prefrail, and robust. We report hazard ratios (HRs) of mortality, adjusting for age, …

The Evolution Of Durable, Implantable Axial-Flow Rotary Blood Pumps, P Alex Smith, Yaxin Wang, O H Frazier

The Texas Heart Institute Journal

Left ventricular assist devices (LVADs) are increasingly used to treat patients with end-stage heart failure. Implantable LVADs were initially developed in the 1960s and 1970s. Because of technological constraints, early LVADs had limited durability (eg, membrane or valve failure) and poor biocompatibility (eg, driveline infections and high rates of hemolysis caused by high shear rates). As the technology has improved over the past 50 years, contemporary rotary LVADs have become smaller, more durable, and less likely to result in infection. A better understanding of hemodynamics and end-organ perfusion also has driven research into the enhanced functionality of rotary LVADs. This …

Medical Professionals’ Perspective On Safety And Efficacy Of Early Mobilization In Acute Heart Failure Patients, Kevin Triangto, Febrian M. Santausa, Basuni Radi, Bambang Budi Siswanto

Journal of the Hong Kong College of Cardiology

Acute heart failure (HF) patients most of the time presents with hemodynamic instability, which often leads to prolonged bedrest. Newer studies had shown that early mobilization for HF patients would lead to better outcomes. However, the early mobilization practice has not always been done due to several barriers in the medical professionals’ perspective, especially regarding safety and efficacy. Prior studies had shown that medical professionals’ views would greatly affect patients’ perspectives, especially in HF rehabilitation. This study is aimed to describe medical professionals’ views on the safety of early mobilization for HF. It was then revealed that General Practitioners’ (GP) …

Faculty, Staff and Student Publications

Medical management of heart failure (HF) has evolved and has achieved significant survival benefits, resulting in highly complex medication regimens. Complex medication regimens create challenges for older adults, including nonadherence and increased adverse drug events, especially associated with cognitive impairment, physical limitations, or lack of social support. However, the association between medication complexity and patients' health outcomes among older adults with HF is unclear. The purpose of this review is to address how the complexity of HF medications has been assessed in the literature and what clinical outcomes are associated with medication regimen complexity in HF. Further, we aimed to …

A Case Of Isolated Cardiac Burkitt Lymphoma Causing Right-Sided Heart Failure, Graham Rector, Stephanie J Koh, Rashed Tabbaa

The Texas Heart Institute Journal

Primary cardiac tumors are rare, as the most common cause of cardiac masses is from metastatic disease. In this article, a unique case of isolated cardiac Burkitt lymphoma causing right-sided heart failure in a 70-year-old man who presented to the emergency department with abdominal distension and lower-extremity swelling is described. The right ventricular mass was initially identified via computed tomographic scans of the abdomen and pelvis. Further workup included transthoracic echocardiogram and cardiac magnetic resonance imaging that showed extension of the mass into the right atrium and pericardium. Staging imaging and bone marrow biopsy revealed no evidence of metastatic disease. …

Effects Of Escalating Temporary Mechanical Circulatory Support In Patients With Worsening Cardiogenic Shock, Iyad N Isseh, Sarah Gorgis, Carina Dagher, Shivani Sharma, Mir B Basir, Sachin Parikh

The Texas Heart Institute Journal

BACKGROUND: Cardiogenic shock-related mortality is substantial, and temporary mechanical circulatory support (MCS) devices are frequently used. The authors aimed to describe patient characteristics and outcomes in patients with worsening cardiogenic shock requiring escalation of temporary MCS devices.

METHODS: Worsening cardiogenic shock was defined as persistent hypotension, increasing doses of vasopressors/inotropes, worsening hypoperfusion, or worsening invasive hemo-dynamics. Escalation of temporary MCS devices was defined as adding or exchanging an existing MCS device. Variables were evaluated by logistic regression models and receiver operating characteristic curves.

RESULTS: From July 1, 2016, to July 1, 2018, a total of 81 consecutive patients experienced worsening …

Diaphragmatic Function In Cardiovascular Disease: Jacc Review Topic Of The Week., Husam M Salah, Lee R Goldberg, Jeroen Molinger, G Michael Felker, Willard Applefeld, Tienush Rassaf, Ryan J Tedford, Michael Mirro Md, Facc, Fhrs, Faha, John G F Cleland, Marat Fudim

Parkview Heart Institute

In addition to the diaphragm's role as the primary respiratory muscle, it also plays an under-recognized role in cardiac function. It serves as a pump facilitating venous and lymph return, modulating left ventricular afterload hemodynamics and pericardial pressures, as well as regulating autonomic tone. Heart failure (HF) is associated with diaphragmatic changes (ie, muscle fiber atrophy and weakness, increased ratio of type I to type II muscle fibers, and altered muscle metaboreflex) that lead to diaphragmatic dysfunction with subsequent symptomatic manifestations of HF. Herein, it is proposed that targeting the diaphragm in patients with HF via inspiratory muscle training or …

Aims: Heart failure (HF) is a common and morbid condition impacting multiple health domains. We previously reported the development of the PROMIS®-Plus-HF (PROMIS+HF) profile measure, including universal and HF-specific items. To facilitate use, we developed shorter, PROMIS+HF profiles intended for research and clinical use.

Methods and results: Candidate items were selected based on psychometric properties and symptom range coverage. HF clinicians (n = 43) rated item importance and clinical actionability. Based on these results, we developed the PROMIS+HF-27 and PROMIS+HF-10 profiles with summary scores (0-100) for overall, physical, mental, and social health. In a cross-sectional sample (n = 600), we …

The Lawnmower And The Pediatric Lower Extremity: A Catastrophic Combination, Alvaro Tamayo-Gutierrez, Hassan N Ibrahim

Faculty, Staff and Student Publications

Heart failure can lead to renal impairment, an interaction now termed "cardiorenal syndrome." The prevalent physiological explanation for the renal impairment that accompanies heart failure centers around the forward failure hypothesis, which emphasizes the role of left ventricular dysfunction in causing edema, and the backward failure hypothesis, which singles out venous congestion as the dominant mechanism of edema and reduced glomerular filtration rate. In this review, we provide an appraisal on venous congestion, an extremely important contributor that has received little attention. We also summarize the pharmacology of loop diuretics, explain current understanding of diuretic resistance, and address controversies regarding …

Sirpα Mediates Igf1 Receptor In Cardiomyopathy-Induced By Chronic Kidney Disease, Sandhya S Thomas, Jiao Wu, Giovanni Davogustto, Michael W Holliday, Kristin Eckel-Mahan, Daniela Verzola, Giacomo Garibotto, Zhaoyong Hu, William E Mitch, Heinrich Taegtmeyer

Faculty, Staff and Student Publications

BACKGROUND: Chronic kidney disease (CKD) is characterized by increased myocardial mass despite near-normal blood pressure, suggesting the presence of a separate trigger. A potential driver is SIRPα (signal regulatory protein alpha)-a mediator impairing insulin signaling. The objective of this study is to assess the role of circulating SIRPα in CKD-induced adverse cardiac remodeling.

METHODS: SIRPα expression was evaluated in mouse models and patients with CKD. Specifically, mutant, muscle-specific, or cardiac muscle-specific SIRPα KO (knockout) mice were examined after subtotal nephrectomy. Cardiac function was assessed by echocardiography. Metabolic responses were confirmed in cultured muscle cells or cardiomyocytes.

RESULTS: We demonstrate that …

The Texas Heart Institute Journal

The United States Food and Drug Administration restricts the use of implantable cardiac pressure monitors to patients with New York Heart Association (NYHA) class III heart failure (HF). We investigated whether single-pressure monitoring could predict survival in HF patients as part of a model constructed using data from the ESCAPE (Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness) trial.

We validated survival models in 204 patients, using all-cause 180-day mortality. Two levels of model complexity were tested: 1) a simplified 1-pressure model based on pulmonary artery mean pressure ([PAM]1P) (information obtainable from an implanted intracardiac monitor alone), …

Prolonged Cardiac Nr4a2 Activation Causes Dilated Cardiomyopathy In Mice, Sadia Ashraf, Heinrich Taegtmeyer, Romain Harmancey

Faculty, Staff and Student Publications

Transcription factors play a fundamental role in cardiovascular adaptation to stress. Nuclear receptor subfamily 4 group A member 2 (NR4A2; NURR1) is an immediate-early gene and transcription factor with a versatile role throughout many organs. In the adult mammalian heart, and particularly in cardiac myocytes, NR4A2 is strongly up-regulated in response to beta-adrenergic stimulation. The physiologic implications of this increase remain unknown. In this study, we aimed to interrogate the consequences of cardiac NR4A2 up-regulation under normal conditions and in response to pressure overload. In mice, tamoxifen-dependent, cardiomyocyte-restricted overexpression of NR4A2 led to cardiomyocyte hypertrophy, left ventricular dilation, heart failure, …
