Patel, Naveena Yanamala, Brijesh Patel, Sameer Raina, Peter D. Farjo, Srinidhi Sunkara, Márton Tokodi, Nobuyuki Kagiyama, Grace Casaclang-Verzosa, Partho P. Sengupta

Journal of Patient-Centered Research and Reviews

Purpose: Electrocardiography (ECG)-derived machine learning models can predict echocardiography (echo)-derived indices of systolic or diastolic function. However, systolic and diastolic dysfunction frequently coexists, which necessitates an integrated assessment for optimal risk-stratification. We explored an ECG-derived model that emulates an echo-derived model that combines multiple parameters for identifying patient phenogroups at risk for major adverse cardiac events (MACE).

Methods: In this substudy of a prospective, multicenter study, patients from 3 institutions (n = 727) formed an internal cohort, and the fourth institution was reserved as an external test set (n = 518). A previously validated patient similarity analysis model was used …

Symposium of Student Scholars

Abstract

A Project Proposal: The Effects of Standard Protocols during CPR on Hospital-Acquired Infections of Post-Open-Heart Surgery Patients in the CVICU

Background: Hospital-acquired infections (HAIs) are one of the most common complications post-cardiac surgeries and are associated with longer hospitalizations, elevated use of healthcare resources, and increased morbidity and mortality. The effects of HAIs after cardio-pulmonary resuscitation (CPR) in recent post-open-heart surgery patients remains largely unexplored. Therefore, the purpose of this project was to determine, in the CVICU does implementing standard protocols during CPR on recent post-open-heart surgery patients reduce HAIs?

Literature Review: HAIs during CPR can be acquired through …

Dronedarone For Atrial Fibrillation Prophylaxis In Patients Undergoing Open Heart Surgical Interventions: A Case Series, Jay D. Patel, Mrhaf Alsamman, Dewansh Goel, Sai Gudduru, Rakesh Prashad

Journal of Community Hospital Internal Medicine Perspectives

Atrial fibrillation (a-fib) is one of the most frequently encountered and studied arrhythmias in medicine. The presence of A-fib in the post-operative period of coronary artery bypass graft (CABG) surgery is of particular concern for clinicians as this presents risks of post-operative stroke, hospital readmission, or anticoagulation dilemmas depending on the patient’s comorbidities. In this case study, we present 5 patients who were treated with dronedarone prior to undergoing open heart procedures. We subsequently followed each patients clinical course paying close attention for any evidence of post-operative a-fib.

Decreased Cognition Is Associated With Altered Cardiovascular Autonomic Functions And Decreased Baroreflex Sensitivity In Women With Premenstrual Syndrome, Jothi Marie Feula, Dhanalakshmi Yerrabelli, Gopal Krushna Pal, Soundirarajan Subhashri

Journal of Mind and Medical Sciences

Premenstrual syndrome (PMS) is a clinical entity of concern in women of reproductive age group with its onset during the late luteal phase of the menstrual cycle that typically resolves within a few days after the onset of menstruation. Female reproductive hormones stimulate the gene promotor region of Gonadal steroids, which are modulators of the hypothalamic-pituitary axis, in association with the autonomic nervous system (ANS), form the stress system, which regulates the homeostatic mechanisms of the body. Disruption of this mechanism can lead to sympathovagal imbalance and cognitive deficits. Objectives: This study was aimed to compare the autonomic functions and …

Jamil, Niklas Luhmann, Pamela Nabeta, Stefano Ongarello, Saeed Hamid

Medical College Documents

Background: Globally, just 21% of the estimated 58 million people living with hepatitis C virus (HCV) know their status. Thus, there is considerable need to scale-up HCV testing if the World Health Organization (WHO) 2030 hepatitis elimination goals are to be achieved. HCV self-testing may assist with this; however, there are currently no data on the real-world impact of HCV self-testing. With an estimated 5% of the general population living with HCV, Pakistan has the second highest HCV burden in the world. This study aims to evaluate the acceptability and impact of home delivery of HCV self-testing for secondary distribution …

Repurposing Probenecid For The Treatment Of Heart Failure (Re-Prosper-Hf): A Study Protocol For A Randomized Placebo-Controlled Clinical Trial, Jack Rubinstein, Nathan Robbins, Karen Evans, Gabrielle Foster, Kevin Mcconeghy, Toluwalope Onadeko, Julie Bunke, Melanie Parent, Xi Luo, Jacob Joseph, Wen-Chih Wu

Faculty, Staff and Student Publications

BACKGROUND: Improving contractility in heart failure with reduced ejection fraction (HFrEF) has resurfaced as a potential treatment goal. Inotropic therapy is now better understood through its underlying mechanism as opposed to the observed effect of increasing contractility. Calcitropes are a subgroup of inotropes that largely depend on the stimulation of adenylyl cyclase to transform ATP into cyclic adenosine monophosphate (cAMP). At least two clinically relevant calcitropes-istaroxime and probenecid-improve contractility through an increase in systolic intracellular calcium without activating cAMP production. Probenecid, which has been safely used clinically for decades in non-cardiac conditions, has recently been identified as an agonist of …

Identification Of Genetic Loci Simultaneously Associated With Multiple Cardiometabolic Traits, Alexis C Wood, Amit Arora, Michelle Newell, Victoria L Bland, Jin Zhou, Nicola Pirastu, Jose M Ordovas, Yann C Klimentidis

Children’s Nutrition Research Center Staff Publications

Background and aims: Cardiometabolic disorders (CMD) arise from a constellation of features such as increased adiposity, hyperlipidemia, hypertension and compromised glucose control. Many genetic loci have shown associations with individual CMD-related traits, but no investigations have focused on simultaneously identifying loci showing associations across all domains. We therefore sought to identify loci associated with risk across seven continuous CMD-related traits.

Methods and results: We conducted separate genome-wide association studies (GWAS) for systolic and diastolic blood pressure (SBP/DBP), hemoglobin A1c (HbA1c), low- and high- density lipoprotein cholesterol (LDL-C/HDL-C), waist-to-hip-ratio (WHR), and triglycerides (TGs) in the UK Biobank (N = 356,574-456,823). Multiple …

Supraventricular Tachycardia Ablation And Its Effects On Anxiety Medications., Mohamed Mahmoud, Justin Haloot, Khadija El Kortbi, Vanessa Rodriguez Fuenmayor, Mubeen Cheema, Auroa Badin

Heart and Vascular Articles

BACKGROUND: Patients with true paroxysmal supraventricular tachycardia (PSVT) are frequently misdiagnosed with panic or anxiety disorders due to similar symptoms of palpitations, light-headedness, dyspnea, or chest discomfort. Unrecognized PSVT can lead to unnecessary management with anxiety medications. Treatment of PSVT with catheter ablation may lead to a reduction in anxiety medications.  Methods: A total of 175 patients underwent successful PSVT ablation between January 1, 2010 and December 31, 2020. We examined symptoms at presentation, psychiatric medications prior to PSVT ablation, comorbidities, and psychiatric medications at three months post-ablation.  Results: Fifteen percent of patients who underwent successful PSVT ablation were being …

What Should Patients Know About Self Blood Pressure Measurement? A Review Article, Sau-Nga Fu

Journal of the Hong Kong College of Cardiology

Many people measure their blood pressure (BP) outside doctors’ offices with a common goal of concerning their health status. Self-BP monitoring devices are widely accessible as health care products or available in different community institutes. Patients often seek their doctors’ advice on their BP readings in our daily practice. Current international guidelines recommend that correct self-BP measurement with validated devices can enhance patients’ self-management and drug compliance, improving overall BP control. While most of the clinicians were supportive of their patients’ efforts, they were also concerned about the validity and reliability of the out-of-office BP readings. How can we effectively …

Pre-Participation Cardiovascular Screening In Athletes With A Focus On Asia, Tee Joo Yeo

Journal of the Hong Kong College of Cardiology

Pre-participation screening (PPS) in young competitive athletes aims to identify conditions associated with sudden cardiac death (SCD) in this population, with a view to appropriate management and potential mitigation of risk. A medical history questionnaire and physical examination are standard components of a PPS programme, whereas controversy still exists regarding mandatory utilisation of resting 12-lead electrocardiogram as a screening tool. Apart from a landmark study from Italy attributing the reduction of SCD rates in athletes to the implementation of a mandatory PPS programme, there remains no additional compelling evidence for similar outcomes to date. Nonetheless, comprehensive PPS programmes when carried …

Myocardial Contraction Fraction Is Superior To Ejection Fraction In Predicting Functional Capacity In Patients With Heart Failure With Reduced Ejection Fraction, Yasser A. Abdellatif, Hassan A. Addow, Ramy R. Elias

Journal of the Saudi Heart Association

Objectives: In this study, we aimed to evaluate the relationship between three-dimensional echocardiography (3DE)- determined myocardial contraction fraction (MCF) and functional capacity in heart failure with reduced ejection fraction (HFrEF) patients. The MCF is a volumetric index of myocardial function, defined as stroke volume ratio to myocardial volume (MV). Functional capacity was evaluated by a 6-min walk test (6MWT), and health-related quality of life (HRQOL) was assessed by the Minnesota Living with Heart Failure Questionnaire (MLHFQ). In view of cardiac remodeling, we hypothesized that MCF would be superior to left ventricular ejection fraction (LVEF) in predicting functional capacity in HFrEF …

Low Voltage-Guided Ablation Of Posterior Wall Improves 5-Year Arrhythmia-Free Survival In Persistent Atrial Fibrillation, Ahmad Jabri, Soufian T. Almahameed, Ohad Ziv

Faculty Scholarship

Introduction: The posterior wall (PW) has been proposed as a standard target for ablation beyond pulmonary vein antral isolation (PVI) in patients with persistent atrial fibrillation (AF). However, studies have shown inconsistent outcomes with the addition of PW ablation. The presence or absence of low voltage on the PW may explain these inconsistencies. We evaluated whether PW ablation based on the presence or absence of low voltage improves long-term arrhythmia-free outcomes. Methods: We retrospectively reviewed 5-year follow-up in 152 consecutive patients who received either standard ablation (SA) with PVI alone or PVI + PW ablation (PWA) based on physician discretion …

The coronavirus disease 2019 (COVID-19) has overwhelming healthcare systems globally. To date, a myriad of therapeutic regimens has been employed in an attempt to curb the ramifications of a severe COVID-19 infection. Amidst the ongoing pandemic, the advent and efficacious uptake of COVID-19 vaccination has significantly reduced disease-related hospitalizations and mortality. Nevertheless, many side-effects are being reported after COVID-19 vaccinations and myocarditis is the most commonly reported sequelae post vaccination. Majority of these diseases are associated with COVID-19 mRNA vaccines. Various studies have established a temporal relationship between these complications, yet the causality and the underlying pathogenesis remain hypothetical. In …

Management Of Hyperkalemia To Prevent Cardiac Arrest, Jennifer Harklerode, Amber Paul, Crystal Zheng, Olivia Vanscoy, Olivia Henton, Mark Olah

Pharmacy and Wellness Review

Hyperkalemia is a metabolic problem that may be life threatening if left untreated. Cardiac arrhythmias may develop with the potential to lead to cardiac arrest and death. Hyperkalemia can oftentimes be undiagnosed due to the lack of clear, specific symptoms and inconclusive variations in electrocardiogram (ECG) readings and lab values. Therefore, it is important to recognize risk factors that can potentially in-crease serum potassium levels. Screening for medications that increase serum potassium levels and educating patients are steps that both inpatient and outpatient health care professionals can take to increase early detection and prevention of a hyperkalemic episode. It is …

Isolated Right Superior Vena Cava Drained To Left Atrium In A Child With Waardenburg Syndrome And Neurofibromatosis Type I, Omer A. Algonaid, Yahya H. Almashham, Abdulrahman S. Almoukirish

Journal of the Saudi Heart Association

Isolated right superior vena cava (SVC) draining to the left atrium (RSVC-LA) is an extremely rare cyanotic congenital heart disease (CHD). Such lesion is easily missed with improper scanning or inattentive interpretation of echocardiography. This can result in potential systemic severe complications. We report a child with RSVC-LA who has two significant non-cardiac co-morbidities, including Waardenburg syndrome and n neurofibromatosis type I (NF1). This patient was referred to cardiology assessment due to unexplained low saturation and was diagnosed as RSVC-LA; however, fortunately not yet showing complications of systemic thromboembolic phenomenon (STEP).
