Atrial fibrillation (AF) often coexists with heart failure, both involving inflammatory signaling and cardiac fibroblasts. To understand the role of fibroblast NLR family pyrin domain containing 3 (NLRP3) inflammasome in cardiac function, we found that NLRP3 was up-regulated in atrial fibroblasts from AF patients. Fibroblast-specific activation of NLRP3 in mice induced AF-promoting atrial myopathy and heart failure with diastolic dysfunction, accompanied by increased fibrosis, and reduced conduction velocity. Knockdown of NLRP3 prevented the AF-promoting atrial substrate and cardiomyopathy in the context of NLRP3 activation in fibroblasts. We identify the fibroblast NLRP3 inflammasome as a key pathway governing the promotion of …

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, …

This paper reviews the potential of intermittent fasting as a non-pharmacological therapeutic approach to the treatment of metabolic syndrome (MetS). MetS is a global health problem with risk factors that include obesity, hypertension, hyperglycemia, low high-density lipoprotein (HDL) cholesterol, and high triglycerides that predispose to cardiovascular disease and type 2 diabetes. Traditional treatment approaches, including pharmacological agents and lifestyle modification, are typically of short-term benefit. Intermittent fasting, with its scheduled cycles of eating and fasting, presents another strategy for improving weight control, insulin sensitivity, lipid profiles, and blood pressure. Various intermittent fasting regimens, including time-restricted feeding and alternate-day fasting, have …

Pharmacogenetic-Guided Antiplatelet Therapy For Personalized Medicine In Patients With Stroke And Transient Ischemic Attack Without Cardioembolic Stroke: A Systematic Review Of Economic Evaluations, Nathapol Samprasit, Chamipa Phanudulkitti, Nattanichcha Kulthanachairojana, Jatapat Hemapanpairoa

The Thai Journal of Pharmaceutical Sciences

Background: Stroke is a major global public health burden. Ischemic stroke is the most common type of all stroke cases worldwide. Antiplatelet therapy is a key strategy for secondary prevention in patients with stroke and transient ischemic attacks (TIAs) without cardioembolic stroke. Dual antiplatelet therapy (DAPT) with clopidogrel is recommended in patients with early mild stroke or high-risk TIA, followed by long-term single antiplatelet therapy (SAPT). Clopidogrel is often used as an alternative for patients with aspirin resistance or intolerance. However, clopidogrel is a prodrug metabolized by the CYP2C19 enzyme, leading to variability in its effectiveness.

Objectives: This study aims …

Potential Strategies For Reducing Mortality And Morbidity In Acute Ischemic Cardiogenic Shock, Richard Smalling, James Mccarthy, Tim Henry, Ali Denktas

Journal of Shock and Hemodynamics

Cardiogenic shock is predominantly caused by acute ischemic myocardial injury. Despite advancements in reperfusion strategies, outcomes remain poor, with the duration of ischemia before reperfusion playing a crucial role in the development of irreversible damage. This review synthesizes insights from animal models and human studies, highlighting the limited myocardial salvage beyond 90 minutes of ischemia. In light of the high mortality rates associated with cardiogenic shock, this review proposes re-evaluating pre-hospital fibrinolysis, exploring left ventricular unloading strategies before reperfusion, and assessing the potential role of endothelin antagonists. These approaches aim to improve outcomes in this high-risk population.

Unmasking Myocardial Bridging: Multimodal Imaging And Tailored Medical Approach In Exercise-Induced Angina – A Case Report, M.A. Amico, M. Casini, E.N. Costanzo, M. Moroni, N. Carrabba

Journal of the Saudi Heart Association

Myocardial bridging (MB) is a congenital coronary anomaly in which a segment of a coronary artery runs intramyocardially. We present the case of a 38-year-old male with myocardial bridging in the mid-left anterior descending artery who developed exerciseinduced angina. This case underscores the importance of recognizing MB as a cause of ischemia that should not be overlooked in the diagnostic workup of patients with angina, especially in younger individuals. A comprehensive diagnostic approach, including multimodality imaging, is essential to uncover the pathology. A tailored pharmacological strategy is recommended. Long-term clinical follow-up is crucial for optimizing symptom management and reducing complications.

The aspirated fluid was brown and cloudy; pathology of the fluid showed meat and vegetable matter consistent with food. She ultimately required esophagectomy with esophagostomy. This case highlights the importance of early recognition of esophageal-pericardial fistulas, as delay in the management carries a high risk for morbidity and …

The Role Of Adolescent Depression Heterogeneity And Resilience Resources In Adulthood Cardiometabolic Health And Depressive Symptoms, Samantha R. Scott

Electronic Theses and Dissertations

Depression in adolescence is a major public health problem and is a risk factor for early-onset cardiometabolic disease. Although adolescent depression is a risk factor for poor cardiometabolic health, depression is heterogeneous and associations may differ by sex. Additionally, if risk factors such as depression can predict adulthood cardiometabolic health, resilience factors (e.g., social, school, neighborhood) that are protective for depression may also be protective for physical health, but this is an ongoing area of research. The goals of the current dissertation were to gain a better understanding of what depressive symptom presentations in adolescents are most concerning for adulthood …

Plug And Coil Procedure For Management Of Large Postinfarct Ventricular Septal Defect, Hussam Al Hennawi, Sergio Flores, Michael Little, Lacy Harville, Ahmad Almomani, Muhammad Hammadah

Abington Jefferson Health Papers

Acute surgical mortality for postinfarction ventricular septal rupture remains alarmingly high at approximately 50%. In comparison, medical mortality is nearly 100% and likely exceeds historical levels because of the declining frequency of these acute surgeries, with many surgeons now performing fewer than 1 or 2 annually. Percutaneous device closure has become a feasible option for managing postinfarction ventricular septal defects in carefully selected patients. However, this technique may be associated with challenges such as significant residual shunting, delayed endothelialization, hemolysis, and extended hospital stays. Here, we present a novel approach using coil packing to enhance closure and reduce shunting.

Persistent Activation Of Cardiac Fibroblasts Contributes To Myocardial Interstitial Fibrosis And Left Ventricular Dysfunction In Heart Failure, Rachel Biggs

MUSC Theses and Dissertations

Heart Failure (HF) is a complex clinical syndrome that is defined by an inability of the heart to meet the oxygen demands of the body. Myocardial interstitial fibrosis (MIF), the diffuse overaccumulation of extracellular matrix (ECM) proteins within the cardiac interstitium, contributes to ventricular dysfunction in HF. Mechanical devices designed to alleviate left ventricular deficiencies, termed left ventricular assist devices (LVADs), provide a pump that delivers oxygenated blood to the aorta thereby decreasing hemodynamic load on the ventricle. This end-stage HF therapy alleviates symptomatic burden for HF patients, however, LVAD support does not reduce MIF in the LV, and myocardial …
