Insights

Cardioembolic stroke research is rapidly advancing, with a surge in publications and international collaboration. Key areas include biomarkers, direct oral anticoagulants for embolic stroke of undetermined source (ESUS), and atrial cardiopathy.

Area of Science:

  • Neurology
  • Bibliometrics
  • Public Health

Background:

  • Cardioembolic stroke (CES) leads to poorer outcomes compared to other ischemic stroke types.
  • A significant increase in research output necessitates a bibliometric analysis to understand trends and contributors.
  • This study aims to analyze the developmental trajectory and key research areas in CES.

Purpose of the Study:

  • To conduct a comprehensive bibliometric analysis of cardioembolic stroke (CES) research.
  • To identify developmental trends, key research hotspots, and major contributors in the CES field.
  • To analyze publication characteristics, keyword networks, and collaborative patterns in CES research.

Main Methods:

  • Bibliometric analysis of 5498 publications from Web of Science Core Collection (2011-2024).
  • Utilized HistCite Pro, CiteSpace, and VOSviewer for data analysis, keyword, and network mapping.
  • Examined publication characteristics, institutional contributions, and country/region participation.

Main Results:

  • The US and Journal of Stroke & Cerebrovascular Diseases were leading contributors.
  • Keyword analysis revealed 6 clusters focusing on biomarkers, CES causes, and direct oral anticoagulant trials for embolic stroke of undetermined source (ESUS).
  • Recent research hotspots include direct oral anticoagulants, ESUS, Mendelian randomization, and atrial cardiopathy.

Conclusions:

  • CES research shows rapid progress with extensive international collaboration.
  • Strengthening global research partnerships can further advance the field.
  • Future research should focus on refined etiological phenotyping and personalized secondary prevention for ESUS and related conditions.

Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Cardiac Output and Stroke Volume01:11

Cardiac Output and Stroke Volume

Cardiac output (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.
In an average resting adult male, the typical cardiac output averages...
Cardiac Output II: Effect of Stroke Volume on Cardiac Output01:22

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
