Journal of the Saudi Heart Association

Drug-coated balloons are an emerging strategy for coronary revascularization. Despite their increasing use, the comparative efficacy of sirolimus- versus paclitaxel-coated balloons (SCB vs PCB) remains uncertain. This updated meta-analysis evaluated clinical and angiographic outcomes of SCB and PCB in percutaneous coronary intervention (PCI). A comprehensive search of PubMed, Scopus, and ScienceDirect was performed on August 28, 2025. Studies directly comparing SCB and PCB were included. The primary endpoint was target lesion failure (TLF), which was defined as cardiac death, target vessel myocardial infarction (TVMI), or target lesion revascularization (TLR). On follow-up angiography, secondary endpoints consisted of minimal lumen diameter (MLD), …

Ct-Derived Epicardial Adipose Tissue Density And Its Association With Systemic Inflammation And Functional Impairment In Heart Failure With Preserved Ejection Fraction: A Prospective Cross-Sectional Study From Oman, Arif Albulushi, Ahmed Tawfek, Ahmed Basuoni

Journal of the Saudi Heart Association

Background: Heart failure with preserved ejection fraction (HFpEF) is strongly influenced by cardiometabolic comorbidity and systemic inflammation. Epicardial adipose tissue (EAT) is a biologically active visceral fat depot in direct contact with the myocardium, and CT-derived EAT density (attenuation) may reflect inflammatory adipose remodeling beyond adipose quantity alone. However, the clinical relevance of EAT density in HFpEF remains uncertain.

Objectives: To evaluate the association of CT-derived EAT density with systemic inflammatory biomarkers, functional capacity, health status, and echocardiographic indices of HFpEF severity in a prospective cross-sectional cohort.

Methods: In a prospective cross-sectional study conducted between January and July 2024 at …

Division of Cardiology Faculty Papers

Risk factors (RF) for permanent pacemaker (PPM) placement in cardiac surgery include valvular operations and redo operations. We aim to identify RF for PPM placement prior to discharge (DC) specifically among redo mitral valvular operations, and to analyze outcomes in this population. Our retrospective review considered 943 patients undergoing redo MV operations between 01/2002 and 12/2021, excluding patients experiencing in-hospital death within 48 hours of their operation and patients with existing PPM or implanted cardiac defibrillator (ICD). Patients (n = 742) were categorized based on whether they received a PPM before DC or not. Of the 742 patients analyzed, 47 …

In Vivo Evidence Of Blood Flow Slippage: Failure Of The No-Slip Boundary Condition Assumption, Alena Jarolímová, Jaroslav Hron, Karel Tůma, Radomír Chabiniok, Josef Málek, Keshava Rajagopal

Division of Cardiology Faculty Papers

The assumption that blood adheres to vessel walls with zero tangential velocity component, the so-called "no-slip" boundary condition, is a foundational premise of cardiovascular fluid dynamics. Whether the no-slip condition holds in vivo, however, remains unknown. Seven healthy adult volunteers underwent cardiovascular magnetic resonance imaging. With four-dimensional flow magnetic resonance imaging of the descending thoracic aorta and modeling blood as a Navier-Stokes fluid, near-wall blood velocities were quantified, and wall shear stress was calculated based on the measured velocity fields. Within the Navier-Stokes data assimilation framework, tangential wall velocities of ∼30-80% of the mean luminal velocity were consistently obtained. These …

Time For A New Whole-Person Care Pathway For Chest Pain Admissions, Dana Kajan, Sabbir Mirza, Alexander M. Ruiz, Anthony Degennaro, Mohamad S. Saad

HCA Healthcare Journal of Medicine

Background

Emergency department (ED) visits for chest pain are common and costly, and ED workup often shows no clear cardiac etiology in low-risk patients. Emerging evidence suggests that social determinants of health (SDOH) such as loneliness, social isolation, and food insecurity contribute to cardiovascular outcomes and chest pain presentations.

Methods

We interviewed 114 patients (>18 years) presenting with chest pain and a thrombolysis in myocardial infarction (TIMI) score less than 4 at our community teaching hospital ED. Structured questionnaires assessed the SDOH triad of loneliness, social isolation, and food insecurity. Dependent variables included systolic blood pressure (SBP) at admission, …

Miopati Atrium, Fibrilasi Atrium, Dan Stroke: Mengungkap Hubungan Tersembunyi, Muhammad Yamin, Mohamad Syahrir Azizi, Anneira Amanda Putri

Jurnal Penyakit Dalam Indonesia

Atrial fibrillation (AF) is the most common arrhythmia and has been long recognized as a cause for atrial thrombus formation leading to cardioembolic stroke. However, recent studies reveal that the relationship between atrial fibrillation and stroke is an association rather than a temporal relationship. Left atrial thrombus formation is associated with vascular risk factor, atrial remodeling, and thrombogenesis. Various atrial electrical and structural markers of atrial myopathy have been linked to ischaemic stroke, even in the absence of AF. In addition to the CHA2DS2-VASc score as a consideration for anticoagulant administration, accurate atrial myopathy markers are needed to allow early …

Patent Ductus Arteriosus Spasm During Percutaneous Device Occlusion In Infants And Children, Hani M. Adel, Ashraf K. Mahmoud

Journal of the Saudi Heart Association

Background: Spasm of ductus arteriosus is an uncommon but significant phenomenon associated with transcatheter patent ductus arteriosus (PDA) occlusion. It can lead to procedural failure, improper device sizing, or even embolization of the occluder device as the spasm subsides post-procedure. Aim of this study is to report the frequency, features, management and outcome of PDA spasm during device closure in a single Egyptian center.

Patients and methods: Over about 3 years, 200 infants and children underwent percutaneous device occlusion. The echocardiographic and catheterization data of patients who developed spasm of PDA before or during or shortly after anesthesia …

Mimickers Of Atrial Fibrillation: When All Irregular Rhythms Are Not Atrial Fibrillation, Tirumala Nischal Jasty, Devi Parvathy Jyothi Ramachandran Nair

Transformative Medicine

Atrial fibrillation (AFib) is the most common sustained cardiac arrhythmia and carries important therapeutic implications, particularly regarding anticoagulation and stroke prevention. However, AFib remains frequently misdiagnosed, often due to overreliance on automated electrocardiogram (ECG) interpretations and failure to recognize alternative causes of rhythm irregularity. This review highlights the fundamental ECG characteristics required for the diagnosis of AFib and emphasizes that not all irregular rhythms represent atrial fibrillation. Through a representative clinical case and discussion of common mimickers—including Mobitz I (Wenckebach) atrioventricular block, premature atrial contractions, blocked premature atrial contractions, multifocal atrial tachycardia, and sinus arrhythmia—we demonstrate key electrocardiographic features that …

Intermittent Fasting In Chronic Heart Failure: A Systematic Review Of Safety And Physiological Outcomes, Zulrahman Erlangga, Prenali Dwisthi Sattwika

Journal of the Saudi Heart Association

Interest in intermittent fasting has expanded substantially due to its reported metabolic effects. However, whether such dietary patterns are safe for individuals living with chronic heart failure remains unclear. This issue is particularly relevant for patients who fast for religious observance, including Ramadan. We therefore performed a systematic review to evaluate the clinical safety and physiological implications of intermittent fasting in stable heart failure populations. The review protocol adhered to established reporting standards for systematic reviews. Multiple electronic databases were systematically searched from inception through December 2025 to identify studies evaluating intermittent fasting in adults with chronic heart failure. Both …

Division of Cardiology Faculty Papers

BACKGROUND: This observational, quality initiative evaluated the impact of changing from a passive (dismissible) to an active (nondismissible without action) electronic health record alert on guideline-recommended lipid-lowering therapy (LLT) prescriptions in patients with recent myocardial infarction at risk for secondary events.

METHODS: We sequentially recruited a retrospective passive-alert (February 2018-July 2019; n=733) and a prospective active-alert (August 2020-January 2022; n=587) cohort of patients who triggered an alert to intensify LLT or order a low-density lipoprotein-cholesterol (LDL-C) test if they had a recent myocardial infarction (within 12 months) and elevated (≥70 mg/dL) or missing LDL-C. Prescribed LLTs and cumulative percentages of …

Differential Roles Of Moesin And Vasp In Β-Catenin-Associated Networks During Zebrafish Heart Regeneration, Allen Rutman

Undergraduate Theses, Capstones, and Recitals

With cardiovascular disease remaining as the leading cause of mortality worldwide, it is largely due to the limited regenerative capacity of the human heart. However, zebrafish (Danio rerio) can fully regenerate cardiac tissue following injury, providing a valuable model for studying the mechanisms of heart repair. To investigate these mechanisms, we used proteomics methods in the past. Proximity labeling is a technique that identifies proteins based on their physical proximity to a protein of interest. It can be applied in organisms and in living cells (Roux et al., 2012; Cho et al., 2020). We used proximity labeling to characterize protein …

Apolipoprotein B100 Predicts Cardiovascular And Limb Events In Type 2 Diabetes Patients With Chronic Limb-Threatening Ischemia, Federico Biscetti, Maria Margherita Rando, Maria Anna Nicolazzi, Flavia Angelini, Roberto Iezzi, Luis H. Eraso, Paul J. Dimuzio, Dario Pitocco, Massimo Massetti, Antonio Gasbarrini, Andrea Flex

Department of Surgery Faculty Papers

BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) and chronic limb-threatening ischemia (CLTI) undergoing lower extremity revascularization (LER) face high risks of major adverse cardiovascular events (MACE) and major adverse limb events (MALE), despite guideline-directed lipid-lowering therapy. Apolipoprotein B100 (ApoB100), reflecting total atherogenic particle number, may identify residual risk beyond LDL-cholesterol (LDL-C). Therefore, we investigated whether baseline ApoB100 levels independently predict MACE and MALE beyond conventional risk factors in this high-risk population.

METHODS: In this prospective cohort study, 167 T2DM patients with CLTI undergoing LER were followed for 12 months with visits at 1, 3, 6, and 12 months post-procedure. …

Intravenous Atropine In Reducing Reperfusion Arrhythmias, Conduction Abnormalities, And Hypotension In Inferior St-Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention, Mohamed Ismail Rashed, Islam Mahmoud Bastawy, Ahmed Lotfy Mohamed, Mohamed Gamaleldin Elewa

Journal of the Saudi Heart Association

Objectives: Inferior ST-segment elevation myocardial infarction is frequently complicated by vagally mediated bradyarrhythmias and hypotension during reperfusion, contributing to increased morbidity. The Bezold–Jarisch reflex has been implicated in this hemodynamic instability; however, evidence supporting prophylactic atropine remains limited. The study evaluated whether intravenous atropine administered immediately before reperfusion reduces clinically meaningful bradyarrhythmias, hypotension, early sustained ventricular arrhythmias, and inpatient major adverse cardiovascular events in patients undergoing primary percutaneous coronary intervention.

Methods: In this prospective single-center, randomized, double-blind, placebo-controlled trial, adults presenting within 12 hours of symptom onset with inferior ST-segment elevation myocardial infarction were randomized 1:1 to intravenous …
