Insights

The rate of acute stroke in Coronavirus Disease 19 (COVID-19) patients is below 2%. Stroke was uncommon in COVID-19 patients, primarily occurring in those with severe lung injury and pre-existing risk factors.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Critical Care Medicine

Background:

  • Coronavirus Disease 19 (COVID-19) is associated with an increased risk of thrombotic events.
  • The precise incidence and causality of acute stroke in COVID-19 patients remain under investigation.

Purpose of the Study:

  • To determine the incidence of acute stroke in patients diagnosed with COVID-19.
  • To identify potential causative links between COVID-19 and stroke events.

Main Methods:

  • A single-center analysis of a prospective database included patients with confirmed COVID-19 and stroke.
  • Demographic, clinical, and imaging data were collected for diagnosis.
  • Etiology was determined through comprehensive diagnostic work-up.

Main Results:

  • 1.02% of COVID-19 patients experienced acute ischemic stroke, and 0.2% had intracranial hemorrhage.
  • In most cases (60% ischemic, 100% hemorrhagic), stroke etiology was unrelated to COVID-19.
  • Only 6 patients had strokes possibly related to COVID-19, all requiring mechanical ventilation; COVID-19 was an independent predictor of mortality in patients undergoing endovascular treatment.

Conclusions:

  • Acute stroke is an uncommon complication of COVID-19, occurring in less than 2% of cases.
  • Most strokes in COVID-19 patients had established risk factors or were unrelated to the infection.
  • COVID-19 was an independent predictor of in-hospital mortality for patients who underwent endovascular treatment for stroke.

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

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...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
