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 …

Background: Heart failure (HF) is a complex clinical syndrome with symptoms and signs that result from any structural or functional impairment of ventricular filling or ejection of blood. Limited data is available regarding the in-hospital outcomes of TAVR compared to SAVR in the octogenarian population with HF.

Methods: The National Inpatient Sample (NIS) database was used to compare TAVR versus SAVR among octogenarians with HF. The primary outcome was in-hospital mortality. The secondary outcome included acute kidney injury (AKI), cerebrovascular accident (CVA), post-procedural stroke, major bleeding, blood transfusions, sudden cardiac arrest (SCA), cardiogenic shock (CS), and mechanical circulatory support (MCS). …

The Kidney In Heart Failure: The Role Of Venous Congestion, Alvaro Tamayo-Gutierrez, Hassan N Ibrahim

Student and Faculty 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 …

The Texas Heart Institute Journal

Background

Since the introduction of cardiac resynchronization therapy (CRT) to improve left ventricular function, the effect of CRT on the right ventricle in patients with heart failure has not been well described.

Methods

We evaluated the effect of CRT on right ventricular systolic function in 20 patients (80% men; mean [SD] age, 58.5 [9.8] y) with cardiomyopathy and right ventricular systolic dysfunction (New York Heart Association class III or IV, left ventricular ejection fraction ≤35%, and QRS interval ≥120 ms). The median follow-up time was 15 months. Right ventricular systolic function, defined as a tricuspid annular plane systolic excursion (TAPSE) …

Parkview Heart Institute

AIMS: Synchronized diaphragmatic stimulation (SDS) modulates intrathoracic and intra-abdominal pressures with favourable effects on cardiac function for patients with a reduced left ventricular ejection fraction (LVEF) and heart failure (HFrEF). VisONE-HF is a first-in-patient, observational study assessing the feasibility and 1 year effects of a novel, minimally invasive SDS device.

METHODS AND RESULTS: The SDS system comprises a pulse generator and two laparoscopically delivered, bipolar, active-fixation leads on the inferior diaphragmatic surface. Fifteen symptomatic men with HFrEF and ischaemic heart disease receiving guideline-recommended therapy were enrolled (age 60 [56, 67] years, New York Heart Association class II [53%] /III [47%], …

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 and Staff 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

Myocardial scintigraphy with technetium-99m pyrophosphate is a minimally invasive technique that can distinguish between transthyretin amyloidosis (ATTR) and light-chain amyloidosis. We present a case in which it helped determine the amyloidosis type in a 74-year-old man with cardiac amyloidosis and multiple previous admissions for acute decompensated heart failure. The patient presented with increasing abdominal girth and bilateral lower extremity edema. His medical history also included atrial fibrillation, liver cirrhosis, hypertension, stage 3 chronic kidney disease, and peripheral vascular disease. We prescribed guideline-directed medical therapy for his acute decompensated heart failure with cardiorenal syndrome and his decompensated cirrhosis. Two years previously, …

Decongestion Models And Metrics In Acute Heart Failure: Escape Data In The Age Of The Implantable Cardiac Pressure Monitor, David Paniagua, Glenn N Levine, Lorraine D Cornwell, Ernesto Jimenez, Biswajit Kar, Hani Jneid, Ali E Denktas, Tony S Ma

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 and Staff 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, …

Diabetes is a major risk factor for cardiovascular diseases, including diabetic cardiomyopathy, atherosclerosis, myocardial infarction, and heart failure. As cardiovascular disease represents the number one cause of death in people with diabetes, there has been a major emphasis on understanding the mechanisms by which diabetes promotes cardiovascular disease, and how antidiabetic therapies impact diabetic heart disease. With a wide array of models to study diabetes (both type 1 and type 2), the field has made major progress in answering these questions. However, each model has its own inherent limitations. Therefore, the purpose of this guidelines document is to provide the …

Synchronized Diaphragmatic Stimulation: A Case Report Of A Novel Extra-Cardiac Intervention For Chronic Heart Failure., Lee R Goldberg, Ana Jorbenadze, Tamaz Shaburishvilli, Michael Mirro Md, Marat Fudim, Michel Zuber, Simon F Stämpfli, Felix C Tanner, Paul Erne, John G Cleland

Parkview Heart Institute

Synchronized diaphragmatic stimulation (SDS) is a novel extra-cardiac device-based therapy for symptomatic heart failure with reduced ejection fraction. SDS provides imperceptible chronic stimulation of the diaphragm through a laparoscopically implanted system consisting of an implantable pulse generator and two sensing/stimulating leads affixed to the inferior surface of the diaphragm delivering imperceptible R-wave gaited pulses that alter intrathoracic pressure improving ventricular filling and cardiac output. We describe, in a man with a history of myocardial infarctions resulting in heart failure and persistent New York Heart Association Class III symptoms despite standard therapies, the successful implantation of SDS resulting in improved quality …

In VR therapy (VRT), VR box glasses were used to promote VR relaxation associated with CT. The hemodynamic parameters evaluated were heart rate, systolic and diastolic blood pressure, oxygen saturation, and double product. To analyze them, Student’s …

Effect Of Calcium Chloride And Isoflurane On Force Frequency Relationship In Canines, Harrison Patrizio, Lawrence Mulligan

Rowan-Virtua Research Day

Proper calcium cycling is critical for a optimally functioning heart.

Improper calcium cycling in humans can contribute to heart failure.

Human calcium cycling is difficult to study due to the risks of damaging the patient’s cardiac tissue.

Risk of further damaging cardiac tissue is substantially increased in a heart failure patient.

Past studies focus on studying the effects of changing calcium cycling in lab rats.

Current research shows limited alternative methods in studying relationships between calcium cycling and FFR in larger mammals.

This project analyzes data to determine the response of the canine force frequency relationship to calcium chloride and …
