Insights

Holter ECG is crucial for detecting atrial fibrillation (AF) and paroxysmal atrial fibrillation (PAF) in cardioembolic stroke patients. This helps identify cardiovascular risk factors for better stroke management.

Area of Science:

  • Cardiology
  • Neurology
  • Medical Diagnostics

Background:

  • Cardioembolic strokes are severe and linked to poor outcomes.
  • Identifying cardiovascular risk factors is essential for managing these strokes.
  • Atrial fibrillation (AF) and paroxysmal atrial fibrillation (PAF) are key concerns.

Purpose of the Study:

  • To evaluate cardiovascular status in acute ischemic stroke patients.
  • To specifically assess the role of persistent AF and PAF.
  • To correlate these findings with stroke type, particularly cardioembolic stroke.

Main Methods:

  • 315 acute ischemic stroke patients were classified into cardioembolic, lacunar, atherothrombotic, and unclassified groups.
  • Standard ECG, 24-hour Holter ECG, and transthoracic echocardiography (UCG) were performed on all patients.
  • Brain imaging and clinical data were used for stroke classification.

Main Results:

  • Persistent AF or PAF was detected in 31.5% of patients via Holter ECG, significantly more in the cardioembolic group (67.6%).
  • Standard ECG identified new-onset AF/PAF in 5.2% of patients, with 13.3% in the cardioembolic group.
  • Echocardiography revealed higher rates of left atrial enlargement and mitral regurgitation in cardioembolic stroke patients.

Conclusions:

  • Holter ECG significantly improves the detection of AF and PAF compared to standard ECG alone.
  • Early detection of AF/PAF is vital for managing patients with cardioembolic stroke.
  • Integrating ECG and echocardiography aids in identifying cardiovascular risks associated with ischemic stroke.

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.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...
Ischemic Stroke ll: Pathophysiology01:15

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...

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
