Clonal Hematopoiesis And Thromboembolic Diseases: A Review, Jaekeun Jung, Jee Hyuk Byun, Janghee Woo
Cardiovascular Research Symposium
Clonal hematopoiesis of indeterminate potential (CHIP) has been identified as a novel risk factor for cardiovascular diseases, primarily mediated by CHIP-induced systemic inflammation. Emerging evidence suggests that CHIP may also contribute to the risk of thromboembolic diseases. This review highlights recent findings on the impact of CHIP on various thromboembolic conditions, such as deep vein thrombosis, pulmonary embolism, chronic thromboembolic pulmonary hypertension, and ischemic stroke. Studies have demonstrated an association between CHIP and an increased risk of deep vein thrombosis, pulmonary embolism, chronic thromboembolic pulmonary hypertension and ischemic stroke. CHIP-induced systemic inflammation may amplify vascular endothelial damage and complement cascade …

This review tracks the discovery of circadian biology in cardiovascular science, starting with early clinical observations of daily changes in heart rate, blood pressure, and cardiovascular events. These patterns suggested that time of day matters, but it was not until the past two decades that the mechanisms and knowledge translation of these rhythms were uncovered. We describe the heart's intrinsic circadian properties and importantly how this leads to regulation of cardiac gene and protein expression, neuroendocrine and vascular rhythms, metabolism, cellular electrophysiology, and cell signaling pathways. Next, we explore emerging themes, including the impact of circadian timing on ischemic injury, …

Methods: We conducted a retrospective in-patient study that included all non-ICU patients admitted on a randomly selected mid-week day at our hospital. A 2-step educational intervention was used separated by a 5-week period. The first, a PowerPoint presentation regarding the updated 2017 …
Impact Of Urban Fine Particulate Matter Exposure On Cardiovascular Health, Shelby P. Briggs
Impact Of Urban Fine Particulate Matter Exposure On Cardiovascular Health, Shelby P. Briggs
Honors Theses
Air pollution, particularly exposure to fine particulate matter (PM2.5), poses a growing threat to cardiopulmonary health. PM2.5 consists of microscopic particles smaller than 2.5 microns in diameter and originates from industrial combustion, transportation, and urban dust. These particles are classified as xenobiotics and are capable of bypassing respiratory defenses to enter systemic circulation, where they cause oxidative stress, inflammation, and cardiovascular dysfunction. This study examines the effects of PM2.5 on cardiovascular function using a murine model. Male C57BL/6 mice were divided into control (saline), subchronic (10 µg), and chronic (100 µg) groups and were exposed weekly for 11 weeks via …

Heart failure with preserved ejection fraction (HFpEF) presents significant treatment challenges. We assessed hydrogen sulfide (H2S) bioavailability in HFpEF patients and 2 animal models: the "2-hit" L-NAME + high-fat diet mouse model and ZSF1 obese rats. H2S levels were significantly reduced in patients and both models, linked to decreased cystathionine-γ-lyase expression and increased sulfide quinone oxidoreductase. Cystathionine-γ-lyase knockout worsened HFpEF, whereas pharmacological supplementation with an H2S donor improved diastolic function and reduced cardiac fibrosis. H2S supplement synergized with GLP-1/glucagon agonist and ameliorated HFpEF. These findings suggest that enhancing H2S bioavailability may provide a novel therapeutic strategy for HFpEF.

BACKGROUND AND OBJECTIVES: Elderly patients with subarachnoid hemorrhage (SAH) face a disproportionately high burden of morbidity and mortality. While endovascular coiling is often favored in this population, direct comparisons with surgical clipping are limited. We conducted a meta-analysis to compare outcomes of clipping versus coiling in SAH patients aged ≥ 60 years.
METHODS: A systematic search of PubMed, Embase, and Cochrane databases identified studies comparing the two treatments in this age group. The primary outcome was a composite of unfavorable outcomes (modified Rankin Scale [mRS] > 2 and mortality). Secondary outcomes included mortality, favorable outcome (mRS 0-2), rebleeding, and hospital length …

Egg White Hydrolysate In Hypertension: A Mechanistic Investigation Of Gut Microbiota Dependent And Independent Pathways, Emerson David Nolasco
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Cardiovascular diseases are one of the leading causes of mortality worldwide in which hypertension is a risk factor. Present pharmacological interventions require long-term adherence to the therapy and are often associated with undesirable side effects. Moreover, treatments have overlooked the role of the microbiome in the development of hypertension. Egg white hydrolysate (EWH) has exhibited antihypertensive properties with potential to be used as a natural alternative for the prevention and management of hypertension. However, EWH peptide’s effect on the gut microbiome remains yet to be elucidated. Studies have described that a portion of the ingested protein can remain undigested as …
Metabolic Regulation Of Cardiac Fibroblast Phenotype And Function., Collin Kleis Wells
Metabolic Regulation Of Cardiac Fibroblast Phenotype And Function., Collin Kleis Wells
Electronic Theses and Dissertations
Cardiac fibroblasts are central effectors of cardiac repair after myocardial infarction (MI). In response to signaling cues, they differentiate to a range of phenotypes with robust capacities to synthesize and secrete extracellular matrix (ECM) and signaling molecules. Although activated fibroblast phenotypes are associated with pronounced changes in metabolism, it remains unclear how the metabolic network upholds the effector functions of fibroblasts in the post-infarcted heart. Here, we identified that critical enzymes in the phosphoenolpyruvate (PEP) cycle, i.e. pyruvate kinase muscle-2 (PKM2) and phosphoenolpyruvate carboxykinase-2 (PCK2), are elevated in the heart after MI and examined their role in regulating post-MI remodeling …

Cholesterol crystal embolization (CCE) results from the release of cholesterol crystals from ruptured atherosclerotic plaques into circulation, resulting in the occlusion of small arteries and arterioles in various organs. Ischemia triggers a systemic inflammatory response resulting in vascular obstruction and organ dysfunction. Kidneys are often involved because of the proximity to the aorta and CCE in the kidneys can result in acute, sub-acute, or chronic kidney disease. There are many known risk factors for renal involvement of CCE, including iatrogenic and spontaneous causes. The pathophysiology of CCE includes complex pathways that lead to acute and chronic effects that can have …

"Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia, with a lifetime risk of approximately 1 in 4 for adults aged 40 years and above. Despite advances in clinical management, AF remains a major public health concern. Its burden extends beyond symptoms; it quadruples the risk of heart failure and increases the likelihood of stroke fivefold – strokes that are often more severe and fatal than those unrelated to AF. In the United States alone, AF-associated healthcare costs exceed $26 billion annually, and the cost is projected to grow as the population ages (Ko et al., 2025). Regarding current treatments, …

Cardiac disease remains a leading cause of maternal morbidity and mortality, particularly in developed countries where improved survival has increased the number of pregnant patients with congenital heart disease. The physiological changes of pregnancy, such as increased blood volume, cardiac output, and hypercoagulability, can exacerbate preexisting cardiac conditions, posing significant anesthetic challenges during cesarean delivery. This review outlines anesthetic strategies for parturients with structural or functional cardiac disease, emphasizing individualized, multidisciplinary care. We examine general and regional anesthesia approaches, intraoperative monitoring, and hemodynamic goals, including fluid balance, venous return optimization, and myocardial oxygen demand reduction. Preoperative risk stratification and coordination …

Redox regulation is crucial for the cardiac action potential, coordinating the sodium-driven depolarization, calcium-mediated plateau formation, and potassium-dependent repolarization processes required for proper heart function. Under physiological conditions, low-level reactive oxygen species (ROS), generated by mitochondria and membrane oxidases, adjust ion channel function and support excitation–contraction coupling. However, when ROS accumulate, they modify a variety of important channel proteins in cardiomyocytes, which commonly results in reducing potassium currents, enhancing sodium and calcium influx, and enhancing intracellular calcium release. These redox-driven alterations disrupt the cardiac rhythm, promote after-depolarizations, impair contractile force, and accelerate the development of heart diseases. Experimental models demonstrate …

Guidelines for management of heart failure with reduced ejection fraction (HFrEF) emphasize personalized care, patient engagement, and shared decision-making. Medications and cardiac rhythm management (CRM) devices are recommended with a high level of evidence. However, there are significant disparities: patients who could benefit from devices are frequently referred too late or not at all. Misconceptions about device therapy and the notion that the needs of patients (especially the prevention of sudden cardiac death) can now be met by expanding drug therapies may play a role in these disparities. This state-of-the-art review is produced by members of the DIRECT HF initiative, …

Patients with post-traumatic stress disorder face increased cardiovascular risk. This study examines shared genetic regions between post-traumatic stress disorder and 246 cardiovascular conditions across electronic health records, 82 cardiac imaging, and health behaviors defined by Life’s Essential 8. Post-traumatic stress disorder is genetically correlated with cardiovascular diagnoses in 33 regions, imaging traits in 4 regions, and health behaviors in 44 regions. Potentially shared causal variants between post-traumatic stress disorder and 17 cardiovascular conditions were observed in 11 regions. Subsequent observational analysis in AllofUS cohort showed post-traumatic stress disorder is associated with 13 diagnoses even after accounting for socioeconomic factors and …

Background
Obesity is a chronic medical condition with a rising prevalence in the United States. A wide range of morbidity and mortality is associated with obesity, with coronary artery disease being among the most common. Ischemic heart disease continues to be the primary cause of death in the United States. Taken together, interventions to minimize the detrimental effects of obesity on patients at risk of heart disease will not only benefit the patient, but the health care system as well.
Methods
In this retrospective study, we used the HCA Healthcare enterprise data warehouse to identify all adult patients who were …
