Heart Failure In The Setting Of Cocaine Abuse… Cause Or Progression? A Case Report., Diana Othon Martinez, Kashif Ali, Elimar Gonzalez Morales, Barbara Malaga-Espinoza, Jian Garcia, Cesar Gutierrez

Research Colloquium

Background: 1 out of 3 substance abuse emergency department visits are related to cocaine. In the US (United States), >5.5 million people consume cocaine. Hospitalizations for heart failure have a similar amount, with 5.7 million. Cocaine's cardiovascular adverse effects arise secondary to sympathetic nervous system stimulation, including decreased myocardial oxygen supply, coronary vasoconstriction, acceleration of atherosclerosis and thrombus formation. Studies have demonstrated contradictory information regarding cardiac anatomical changes (dilation/hypertrophy) secondary to chronic cocaine use. Cocaine cessation and guideline- directed medical therapy (GDMT) for HF are mainstay management. We present a case of a patient with HF and cocaine abuse.

Recurrent Atrial Myxoma And Transient Ischemic Atack, Abdel Martinez Borrego, Benito Moran Herrera, Eduardo Flores

Research Colloquium

Background: Myxomas are the most common primary cardiac neoplasms and are predominantly located in the left atrium, accounting for approximately 80% of cases. Clinical manifestations can vary widely, ranging from asymptomatic to severe, with potential embolic or obstructive symptoms. Diagnosis is typically made through echocardiography, although CT and MRI can also be useful diagnostic tools. The primary treatment is surgical resection; however, long-term follow-up is essential due to the risk of recurrence, which may occur up to 10 years after the initial surgery.

Case presentation: A 54-year-old female patient with a history of a 5x3x2 cm left atrial …

Integrating Artificial Intelligence With Electrocardiograms: A New Era In Cardiac Care, Abdel Martinez Borrego, Eduardo Flores

Research Colloquium

Background: The integration of artificial intelligence with electrocardiography has significantly transformed contemporary medical practice, representing a major advancement in cardiac care. These algorithms have enhanced the detection of subtle ECG patterns, improving the diagnosis of conditions such as arrhythmias and providing a more accurate diagnostic environment. However, challenges such as data privacy, algorithm transparency, and clinical integration remain. AI holds substantial potential for improving diagnostic accuracy, with several FDA-approved devices now available in the market aimed at enhancing patient outcomes. Future efforts should focus on further validation, implementation, and research to fully realize AI's capabilities in this field.

Unveiling The Neurological Aftermath: Pres After Cardiac Arrest, Oyinlola O. Fasehun, Jessica Daza, Sriharsha Koneru, Victor Tran, Eunbee Cho, Fatimah Bello

Research Colloquium

Background: Posterior Reversible Encephalopathy Syndrome (PRES), also known as ‘Reversible Posterior Leukoencephalopathy Syndrome (RPLS)’, is a clinical radiographic syndrome originally described by Hinchey et al in 1996. PRES has been significantly underdiagnosed due to difficulty in confirmation. As such, there is currently no epidemiological data regarding its incidence, but it has been diagnosed in all age groups with a preponderance in females. A variety of medical conditions have been implicated as causes of PRES, including severe hypertension, immunosuppressive therapy, sepsis, renal diseases and autoimmune disorders. The mechanism of PRES is thought to be related to disordered cerebral autoregulation and endothelial …

A Vascular Puzzle: Identifying High-Output Heart Failure In A Patient With End-Stage Renal Disease And A Fresh Arteriovenous Fistula, Carlos Luis Alejos Aguero, Khiem Ng, Jennifer Rojas Huen, Liza Salloum, James Stone

Research Colloquium

Introduction: We present a case highlighting high-output heart failure secondary to an acquired arteriovenous fistula for dialysis. High-output cardiac failure is a less common form of heart failure characterized by the heart pumping an increased volume of blood but failing to meet the body's metabolic demands.

Case presentation: A 74-year-old female with a history of hypertension, dyslipidemia, type 2 Diabetes, and end-stage renal disease (ESRD) on hemodialysis via a left arteriovenous fistula. She presented with worsening dyspnea over 2-3 months, initially relieved post-dialysis but progressing to dyspnea at rest, orthopnea, and paroxysmal nocturnal dyspnea despite dialysis compliance. Physical exam revealed …

Cardiomyocyte-Derived Small Extracellular Vesicle: A New Mechanism Driving Diabetic Cardiac Fibrosis And Cardiomyopathy, Yu Li, Yunhui Du, Yang Liu, Xiuhuan Chen, Xinxin Li, Yanru Duan, Yanwen Qin, Huirong Liu, Xinliang Ma, Shaoping Nie, Huina Zhang

Department of Emergency Medicine Faculty Papers

Rationale: Diabetic cardiomyopathy is one of the major diabetic cardiovascular complications in which fibrosis plays a critical pathogenetic role. However, the precise mechanisms by which diabetes triggers cardiac fibrosis in the heart remain elusive. Small extracellular vesicles (sEVs) play an important role in the cellular communication. Nevertheless, whether and how diabetes may adversely alter sEVs-mediated cardiomyocyte-fibroblast communication, promoting diabetic cardiac fibrosis and contributing to diabetic cardiomyopathy, has not been previously investigated. Methods and results: High-fat diet (HFD)-induced and genetic (db/db) type 2 diabetic models were utilized. Cardiomyocyte sEVs (Myo-sEVs) were isolated by ultracentrifugation. Normal cardiomyocyte-derived Myo-sEVs attenuated diabetic cardiac fibrosis …

Division of Cardiology Faculty Papers

UNLABELLED: Chronic thromboembolic pulmonary hypertension (CTEPH) is a complication of incomplete resolution of acute pulmonary embolism. We hypothesize changes in CT Hounsfield Unit gradient (HU-Δ) created by the dispersion of IV contrast through the downstream blood pool correlate with cardiac index (CI). We sought to compare HU-Δ with invasively obtained CI.

METHODS: We completed a retrospective analysis of CTEPH patients in which individuals with low CI (<2.2-L/min/m²) were identified. Both absolute and fractional HU-Δ were derived from pulmonary CTA by subtracting the HU value of the left atrium (LA) and left ventricle (LV) from the main pulmonary artery …

Consensus Of The National Heart Center In Collaboration With The Saudi Arabian Cardiac Interventional Society On The Clinical Use Of Intracoronary Imaging, Mirvat Alasnag, Mognee Alameer, Ahmed Alshehri, Hind Alosaimi, Faisal Alqoofi, Hussain Alzayer, Wail Alkashkari, Adel Tash, Waqar H Ahmed

Journal of the Saudi Heart Association

Objectives: Studies show that intracoronary imaging (ICI)-guided PCI is associated with a significantly lower risk of stroke, Q-wave myocardial infarction, and death compared to angiography-guided PCI in the management of acute coronary syndromes, complex coronary lesions and left-main interventions. Despite these well-established clinical benefits, the utilization of ICI-guided PCI in Saudi Arabia remains suboptimal.

Methods: The National Heart Center (NHC) and the Saudi Arabian Cardiac Interventional Society (SACIS) gathered national experts to develop a consensus document on how to integrate ICI-guided PCI in routine clinical practice in Saudi Arabia. The consensus was based on the nominal group technique, whereby a …

Transcatheter Closure Of Complex Multifenestrated Atrial Septal Defect Using Three Septal Occluders: Is Three Too Many?, Hussam Al Hennawi, Appa Bandi, Ahmad Abulshamat, Shaurya Srivastava, Mohammed Qintar

Abington Jefferson Health Papers

Atrial septal defects (ASDs) are a common form of adult congenital heart disease, with surgical or transcatheter closure being the mainstay of treatment in patients with hemodynamic or clinical complications. Transcatheter repair of secundum ASD is safe and effective. Complex secundum ASDs with multifenestrated defects pose a unique challenge to transcatheter repair. We report a successful but complex transcatheter closure of an ASD using three overlapping Amplazter devices.

Division of Cardiology Faculty Papers

Background: Despite oral anticoagulation, patients with atrial fibrillation (AF) remain at risk of ischemic stroke and systemic embolism (SE) events. For patients whose residual risk is sufficiently high, additional therapies might be useful to mitigate stroke risk.

Methods and results: Individual patient data from 5 landmark trials testing oral anticoagulation in AF were pooled in A Collaboration Between Multiple Institutions to Better Investigate Non-Vitamin K Antagonist Oral Anticoagulant Use in AF (COMBINE AF). We calculated the rate of ischemic stroke/SE among oral anticoagulation-treated patients with a CHA₂DS₂-VASc score≥2, across strata of CHA₂DS₂-VASc …

Enhancement Of High-Density Lipoprotein-Associated Protease Inhibitor Activity Prevents Atherosclerosis Progression, Maura Mobilia, Alexander A. Karakashian, Khaga R. Neupane, Olivia Hage, Callie Whitus, Abigail Carter, Clairity Voy, Lance A. Johnson, Gregory A. Graf, Scott M. Gordon

Saha Cardiovascular Research Center Faculty Publications

Background and aims: Inflammatory cells within atherosclerotic lesions secrete proteolytic enzymes that contribute to lesion progression and destabilization, increasing the risk for an acute cardiovascular event. Elastase is a serine protease, secreted by macrophages and neutrophils, that may contribute to the development of unstable plaque. We previously reported interaction of endogenous protease-inhibitor proteins with high- density lipoprotein (HDL), including alpha-1-antitrypsin, an inhibitor of elastase. These findings support a potential role for HDL as a modulator of protease activity. In this study, we test the hypothesis that enhancement of HDL-associated elastase inhibitor activity is protective against atherosclerotic lesion progression.

Methods: We …

IMPORTANCE: In-hospital cardiac arrest (IHCA) is a significant public health burden. Rates of return of spontaneous circulation (ROSC) have been improving, but the best way to care for patients after the initial resuscitation remains poorly understood, and improvements in survival to discharge are stagnant. Existing North American cardiac arrest databases lack comprehensive data on the post-resuscitation period, and we do not know current post-IHCA practice patterns. To address this gap, we developed the Discover In-Hospital Cardiac Arrest (Discover IHCA) study, which will thoroughly evaluate current post-IHCA care practices across a diverse cohort.

OBJECTIVES: Our study collects granular data on post-IHCA …

The male predominance in sporadic thoracic aortic aneurysm and dissection (TAD) suggests that the X chromosome contributes to TAD, but this has not been tested. We investigated whether X-linked variation-common (minor allele frequency [MAF] ≥0.01) and rare (MAF < 0.01)-was associated with sporadic TAD in three cohorts of European descent (Discovery: 364 cases, 874 controls; Replication: 516 cases, 440,131 controls, and ARIC [Atherosclerosis Risk in Communities study]: 753 cases, 2247 controls). For analysis of common variants, we applied a sex-stratified logistic regression model followed by a meta-analysis of sex-specific odds ratios. Furthermore, we conducted a meta-analysis of overlapping common variants between the Discovery and Replication cohorts. For analysis of rare variants, we used a sex-stratified optimized sequence kernel association test model. Common variants results showed no statistically significant findings in the Discovery cohort. An intergenic common variant near SPANXN1 was statistically significant in the Replication cohort (p = 1.81 × 10-8). The highest signal from the meta-analysis of the Discovery and Replication cohorts was a ZNF182 intronic common variant (p = 3.5 × 10-6). In rare variants results, RTL9 reached statistical significance (p = 5.15 × 10-5). Although most of our results were statistically insignificant, our analysis is the most comprehensive X-chromosome association analysis of sporadic TAD to date.

Purpose of review: Major Depressive Disorder (MDD) is characterized by persistent symptoms such as fatigue, loss of interest in activities, feelings of sadness and worthlessness. MDD often coexist with cardiovascular disease (CVD), yet the precise link between these conditions remains unclear. This review explores factors underlying the development of MDD and CVD, including genetic, epigenetic, platelet activation, inflammation, hypothalamic-pituitary-adrenal (HPA) axis activation, endothelial cell (EC) dysfunction, and blood-brain barrier (BBB) disruption.

Recent findings: Single nucleotide polymorphisms (SNPs) in the membrane-associated guanylate kinase WW and PDZ domain-containing protein 1 (MAGI-1) are associated with neuroticism and psychiatric disorders including MDD. SNPs in …
