Left Ventricular Ballooning Patterns In Recurrent Takotsubo Cardiomyopathy: A Systematic Review And Meta-Analysis Of Reported Cases, Ravi Korabathina, Jamie Porcadas, Kevin E Kip, Puja R Korabathina, Andrew D Rosenthal, Peter Wassmer

The Texas Heart Institute Journal

Recurrent takotsubo cardiomyopathy (TTC) and the clinical profiles and outcomes of patients have not been fully evaluated, nor has the effect of left ventricular ballooning pattern. After searching the medical literature for reports of patients with recurrent TTC, we identified 84 articles with 101 case descriptions. We divided the cases into those with only apical left ventricular ballooning patterns at recurrence (typical, n=60), and those with at least one midventricular or basal ballooning pattern (atypical, n=41). We then compared their clinical profiles and outcomes.

The groups were similar in terms of baseline demographic characteristics, presence and types of triggers, use …

Endovascular Treatment Of Acquired Atheromatous Postsubclavian Aortic Coarctation, Bhushan S Sonawane, Sreeja Pavithran, Kothandam Sivakumar

The Texas Heart Institute Journal

Coral reef aorta is a rare calcifying obstructive disease that involves the thoracoabdominal aorta. Similar presentations in the postsubclavian aorta may result in acquired atheromatous aortic coarctation leading to systemic hypertension and heart failure. The associated calcification makes surgical anatomic or extraanatomic bypass and thromboendarterectomy challenging. Extensive circumferential calcification often precludes endovascular intervention. We present the case of a 25-year-old man with an acquired atheromatous coarctation of the postsubclavian aorta who underwent successful endovascular treatment with use of a balloon-expandable covered stent.

Patient Characteristics And Outcomes Of Type 2 Myocardial Infarction During Heart Failure Hospitalizations In The United States, Salik Nazir, Abdul Mannan Khan Minhas, Ishan S Kamat, Robert W Ariss, George V Moukarbel, Juan Carlos Plana Gomez, Savitri Fedson, Ajith Nair, Biykem Bozkurt, Hani Jneid

Faculty, Staff and Students Publications

BACKGROUND: Type 2 myocardial infarction (MI) is increasingly diagnosed in patients with heart failure (HF). A paucity of data exists pertinent to the contemporary prevalence and impact of type 2 MI in patients with HF. We studied the patient profiles and the prognostic impact of type 2 MI on outcomes of HF hospitalizations.

METHODS: The Nationwide Readmission Database 2018 was queried for patients with HF hospitalizations with and without type 2 MI. Baseline characteristics, inpatient outcomes, and 30-day all-cause readmissions between both cohorts were compared.

RESULTS: Of 1,072,674 primary HF hospitalizations included in the study, 28,813 (2.7%) had type 2 …

A Rollout Of A Blood Pressure Remote Patient Monitoring Program To Improve High-Risk Maternal Outcomes At A Pilot Clinic For Systemwide Expansion, Laura Geron

Seton Hall University Dissertations and Theses (ETDs)

An existing virtual care platform provides an innovative means of early recognition, identification, and intervention for women with elevated blood pressures during pregnancy, known as preeclampsia. A pilot program took place at a Northeastern prenatal care clinic where patients were identified as high-risk for preeclampsia, enrolled, educated by their providers, and equipped with Bluetooth-enabled blood pressure cuffs.

Through remote patient monitoring (RPM) technology, blood pressure readings could transmit from a patient’s residence to a portal accessible by their clinic provider at any time. This doctoral-level quality improvement project focuses on the identification of patients at high-risk for preeclampsia, their enrollment …

Integrating Patient-Reported Outcomes Into Clinical Genetic Testing For Familial Hypercholesterolemia, Rachele M. Hendricks-Sturrup, Robert Block, Christine Y. Lu

Journal of Patient-Centered Research and Reviews

Patient-reported outcomes (PROs) and PRO measures (PROMs) are often used to help clinicians and researchers understand patients’ personal concerns, feelings, experiences, and perspectives following the implementation of an intervention. Notably, PROs and PROMs can inform health systems, health policy, and payers on the utility of clinical genetic testing based on each patient’s personal values, perspectives, and potential health behaviors subsequent to testing. In this topic synopsis, we discuss the underexplored role of and implications for PROs and PROMs following genetic testing for familial hypercholesterolemia (FH), an autosomal dominant genetic disorder of cholesterol metabolism that can lead to highly premature fatal …

A Novel Code Team Leader Card To Improve Leader Identification, Palak Shah, Vinod Havalad

Journal of Patient-Centered Research and Reviews

Prompt and clear code team leader identification is vital in effective cardiopulmonary resuscitation (CPR), and pediatric trainees often have limited experience in these scenarios. This project sought to develop a tangible object that provided clear leader identification and assisted in code team management and simulated team training. A Code Team Leader Card (CTLC) was designed to provide clear leader identification while simultaneously providing a cognitive aid via integration of pediatric advanced life support (PALS) algorithms. Additionally, CTLC served to occupy the leader’s hands to limit their ability to intervene on procedural tasks. The CTLC was incorporated into pediatric resident simulation …

Mental Health Or Cardiac Health. Is There A Reason To Choose? Cardiac Arrhythmias Induced By Atomoxetine And Methylphenidate, Gabriel Cismaru, Viorel Lupu

Journal of Mind and Medical Sciences

The current treatment of Attention Deficit Disorder and Attention Deficit with Hyperactivity consists mainly in the administration of Straterra (Atomoxetine) Concerta and Ritalin (Methylphenidate). The FDA warned that the products might increase systolic, diastolic blood pressure, and lead to ventricular arrhythmias. Arrhythmic events and sudden cardiac death were described in adults with preexistent heart disease. However, studies on children have failed to demonstrate a clear association between the arrhythmic events and these drugs, as demonstrated in adults. What should the attitude of the pediatric psychiatrist be towards the administration of these products? What examination should be made by the psychiatrist …

Hepatocellular Carcinoma With Extrahepatic Blood Supply From Right Renal Artery, Amir Humza Sohail, Ahmad Musa, Muhammad Salman Khan, Hassan Raza Hashmi, Basit Salam, Collin E M. Brathwaite

Department of Radiology

Extrahepatic blood supply is seen in around 17-27% of hepatocellular carcinoma lesions. Evidence suggests that this extrahepatic supply most commonly originates from a right intercostal artery (70-83%) followed by left intercostal, omental and right renal arteries. Thus a comprehensive knowledge of variations in standard vascular anatomy and cognisance of factors influencing or predicting extrahepatic blood supply in HCC is instrumental in ensuring the success of surgical and interventional procedures. We present the unusual case of a 66-year-old male with HCC in Segment I of the liver with aberrant blood supply from the right renal artery in the absence of any …

Phds/Cpt1b/Vdac1 Axis Regulates Long-Chain Fatty Acid Oxidation In Cardiomyocytes, Aude Angelini, Pradip K Saha, Antrix Jain, Sung Yun Jung, Randall L Mynatt, Xinchun Pi, Liang Xie

Faculty, Staff and Students Publications

Cardiac metabolism is a high-oxygen-consuming process, showing a preference for long-chain fatty acid (LCFA) as the fuel source under physiological conditions. However, a metabolic switch (favoring glucose instead of LCFA) is commonly reported in ischemic or late-stage failing hearts. The mechanism regulating this metabolic switch remains poorly understood. Here, we report that loss of PHD2/3, the cellular oxygen sensors, blocks LCFA mitochondria uptake and β-oxidation in cardiomyocytes. In high-fat-fed mice, PHD2/3 deficiency improves glucose metabolism but exacerbates the cardiac defects. Mechanistically, we find that PHD2/3 bind to CPT1B, a key enzyme of mitochondrial LCFA uptake, promoting CPT1B-P295 hydroxylation. Further, we …

Isolated Diastolic Hypertension In The Idaco Study: An Age-Stratified Analysis Using 24-Hour Ambulatory Blood Pressure Measurements, John W. Mcevoy, Wen-Yi Yang, Lutgarde Thijs, Zhen-Yu Zhang, Jesus D. Melgarejo, José Boggia, Tine W. Hansen, Kei Asayama, Takayoshi Ohkubo, Gladys E. Maestre

School of Medicine Publications

The prognostic implications of isolated diastolic hypertension (IDH), as defined by 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines, have not been tested using ambulatory blood pressure (BP) monitor thresholds (ie, 24-hour mean systolic BP ≥75 mm Hg). We analyzed data from 11 135 participants in the IDACO (International Database on Ambulatory Blood Pressure in Relation to Cardiovascular Outcomes). Using 24-hour mean ambulatory BP monitor values, we performed Cox regression testing independent associations of IDH with death or cardiovascular events. Analyses were conducted in the cohort overall, as well as after age stratification (≥50 years). The median age …

Cardiovascular Health Intervention In Firefighters, Kyle T. Manuel

Selected Honors Theses

As each year passes, a fatal cardiovascular event continues to be the leading cause of death among on-duty firefighters. Risk factors for a fatal cardiovascular event and cardiovascular health disease (CVD) are obesity, sleep deprivation, weight gain, lack of exercise, unhealthy diet, etc. The research in this thesis lays out the poor association between cardiovascular health and firefighters. Interventional programs that aim to improve the cardiovascular health of firefighters must be implemented universally to all fire departments by the International Association of Firefighters. Pertinent information collected on the cardiovascular health of surveyed firefighters of Hernando County was paradoxical. While most …

Cellular Regeneration As A Potential Strategy To Treat Cardiac Conduction Disorders, Satadru K Lahiri, Mohit M Hulsurkar, Xander Ht Wehrens

Faculty, Staff and Students Publications

Loss of atrioventricular conduction system (AVCS) cells due to either inherited or acquired deficits leads to conduction diseases, which can deteriorate into fatal cardiac arrhythmias and sudden death. In this issue of the JCI, Wang et al. constructed a mouse model of atrioventricular block (AVB) by inducing AVCS cell-specific injury using the Cx30.2 enhancer to drive expression of diphtheria toxin fragment A. AVCS cell ablation in adult mice led to irreversible AVB. jkjkIn contrast, AVCS cell injury in neonatal mice was followed by spontaneous recovery in a subset of mice, revealing a limited postnatal time window during which the regeneration …

Ucp3 (Uncoupling Protein 3) Insufficiency Exacerbates Left Ventricular Diastolic Dysfunction During Angiotensin Ii-Induced Hypertension, Xu Chen, Sadia Ashraf, Nadia Ashraf, Romain Harmancey

Faculty, Staff and Student Publications

Background Left ventricular diastolic dysfunction, an early stage in the pathogenesis of heart failure with preserved ejection fraction, is exacerbated by joint exposure to hypertension and obesity; however, the molecular mechanisms involved remain uncertain. The mitochondrial UCP3 (uncoupling protein 3) is downregulated in the heart with obesity. Here, we used a rat model of UCP3 haploinsufficiency (ucp3

Angiogenesis' Effect Overall On Health And Disease, Wendy Tang

The Cardinal Edge

Angiogenesis plays a major role in the development of diseases and cancer. The development of illnesses like metastatic breast cancer, cell carcinomas, tumors and various other illnesses, originate from the activation of endothelial cells. When the vascular endothelial growth factor (VEGF) is released from hypoxic tissues, they bind to vascular endothelial growth factor receptors (VEGFR). The binding of VEGF and VEGFR allows for cellular proliferation, increased migration of lattice networks, and the invasion of endothelial cells, which stimulate the formation of new blood vessels from pre-existing ones. As a result, it can be concluded that the inhibition of VEGFs would …

Endothelium-Specific Depletion Of Lrp1 Improves Glucose Homeostasis Through Inducing Osteocalcin, Hua Mao, Luge Li, Qiying Fan, Aude Angelini, Pradip K Saha, Cristian Coarfa, Kimal Rajapakshe, Dimuthu Perera, Jizhong Cheng, Huaizhu Wu, Christie M Ballantyne, Zheng Sun, Liang Xie, Xinchun Pi

Faculty, Staff and Students Publications

The vascular endothelium is present within metabolic organs and actively regulates energy metabolism. Here we show osteocalcin, recognized as a bone-secreted metabolic hormone, is expressed in mouse primary endothelial cells isolated from heart, lung and liver. In human osteocalcin promoter-driven green fluorescent protein transgenic mice, green fluorescent protein signals are enriched in endothelial cells lining aorta, small vessels and capillaries and abundant in aorta, skeletal muscle and eye of adult mice. The depletion of lipoprotein receptor-related protein 1 induces osteocalcin through a Forkhead box O -dependent pathway in endothelial cells. Whereas depletion of osteocalcin abolishes the glucose-lowering effect of low-density …

Background: COVID-19 pandemic has introduced us to a greater need of virtual learning platforms and has resulted in less clinical exposure for fellows-in-training. Virtual and simulator-based learning is not widely available in LMIC. It is imperative to analyze feedback of CV fellow-in-training regarding this mode of learning before large scale implementation.
Methodology: This was an observational study conducted between July-August 2020. A multicentered survey was conducted. Survey questionnaire was disseminated to FIT (fellow-in-training) via Google Forms. The questionnaire contained a total of 24 questions about virtual and simulator-based learning during the pandemic.
Results: A total of 68 FIT responded to …

High Shear Stress Enhances Endothelial Permeability In The Presence Of The Risk Haplotype At 9p21.3, Evan L. Tang, Evan M. Masutami, Benjamin Yeoman, Jessica Fung, Rachel Lian, Brenda Ngo, Aditya Kumar, Jesse K. Placone, Valentina Lo Sardo, Adam J. Engler

Physics & Engineering Faculty Publications

Single nucleotide polymorphisms (SNPs) are exceedingly common in non-coding loci, and while they are significantly associated with a myriad of diseases, their specific impact on cellular dysfunction remains unclear. Here, we show that when exposed to external stressors, the presence of risk SNPs in the 9p21.3 coronary artery disease (CAD) risk locus increases endothelial monolayer and microvessel dysfunction. Endothelial cells (ECs) derived from induced pluripotent stem cells of patients carrying the risk haplotype (R/R WT) differentiated similarly to their non-risk and isogenic knockout (R/R KO) counterparts. Monolayers exhibited greater permeability and reactive oxygen species signaling when the risk haplotype was …

Role Of Sodium-Glucose Cotransporter-2 Inhibitors In Readmissions For Congestive Heart Failure, Joseph Keryakos, Robert Kranz, Rachel Propst, Jena Rathert, Kelli Semerad

Faculty Work Comprehensive List

Background: Patients with type II diabetes are at major risk for cardiovascular disease. Sodium-glucose cotransporter-2 inhibitors (SGLT-2 inhibitors) have demonstrated benefit for these patients. The purpose of this study is to determine whether SGLT-2 inhibitors significantly reduce heart failure readmission rates and improve outcomes in patients with congestive heart failure (CHF).

Methods: Patient data was pulled on CHF patients with an active prescription for an SGLT-2 inhibitor, and it was analyzed using Fischer’s Exact tests and two-tailed t-tests. The primary outcome was a 6-month hospital readmission rate due to CHF while taking SGLT-2 inhibitors. Secondary outcomes included 6-month …

The Texas Heart Institute Journal

During the coronavirus disease 2019 (COVID-19) pandemic, social distancing guidelines have negatively affected the care-seeking behavior of patients with chronic medical conditions, including those with cardiovascular disease. We report the case of a 60-year-old man with vague gastrointestinal symptoms who waited more than 1 week to seek treatment for fear of COVID-19 infection. On presentation at another hospital, he was found to have had an anterior myocardial infarction, and he underwent percutaneous coronary intervention to stent an occluded proximal left anterior descending coronary artery. Subsequently, the patient experienced refractory cardiogenic shock and, during his transfer to our hospital, refractory ventricular …

Cheyne-Stokes Respiration In A 17-Year-Old Boy Awaiting Heart Transplantation, Nooralam A Rai, Aliva De, Carin Lamm

The Texas Heart Institute Journal

Cheyne-Stokes respiration is a pattern of alternating central apnea and hyperpnea. It is well described in adults with congestive heart failure, but not in children.

We report the case of a 17-year-old boy whose systolic heart failure was complicated by Cheyne-Stokes respiration. He was given supportive therapy until heart transplant, after which his Cheyne-Stokes respiration clinically resolved. Clinicians should be aware of this uncommon condition in pediatric and adolescent patients who have advanced heart failure and irregular breathing.

Endoleaks: Current Concepts And Treatments - A Narrative Review, Zia Ur Rehman

Department of Surgery Docs

Endoleaks are the most common complications following endovascular aneurysm repair. Depending upon their origin, there are five types of endoleaks, types I-V, which can also be classified as direct and indirect endoleaks. Direct endoleaks (type I and III) have higher risk of aneurysm rupture due to rapid sac expansion, and require immediate correction. Indirect endoleaks ( type II, IV and V) have a relatively benign course compared to direct endoleaks. Most of them resolve with time and very few need interventions upon sac enlargement. Type V endotension is a special situation where there is sac enlargement despite no demonstrable endoleak. …

Faculty, Staff and Students Publications

BACKGROUND: Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) has emerged as a safe, effective alternative to redo aortic valve surgery in high-risk patients with degenerated surgical bioprosthetic valves. However, ViV-TAVR has been associated high postprocedural valvular gradients, compared with TAVR for native-valve aortic stenosis.

METHODS: We performed a retrospective study of all patients who underwent ViV-TAVR for a degenerated aortic valve bioprosthesis between January 1, 2013 and March 31, 2019 at our center. The primary outcome was postprocedural mean aortic valve gradient. Outcomes were compared across surgical valve type (stented versus stentless), surgical valve internal diameter (≤19 versus >19 mm), and …

Continuous-Flow Left Ventricular Assist Device Support In Patients With Ischemic Versus Nonischemic Cardiomyopathy, Brendan P Chou, Andre Critsinelis, Harveen K Lamba, Gregory Long, Andrew B Civitello, Reynolds M Delgado, Subhasis Chatterjee

Faculty, Staff and Students Publications

To determine whether the cause of cardiomyopathy affects outcomes in patients who undergo continuous-flow left ventricular assist device support, we compared postimplant adverse events and survival between patients with ischemic and nonischemic cardiomyopathy. The inclusion criteria for the ischemic group were a history of myocardial infarction or revascularization (coronary artery bypass grafting or percutaneous coronary intervention), ≥75% stenosis of the left main or proximal left anterior descending coronary artery, or ≥75% stenosis of ≥2 epicardial vessels. From November 2003 through March 2016, 526 patients underwent device support: 256 (48.7%) in the ischemic group and 270 (51.3%) in the nonischemic group. …
