Insights
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause stroke in patients by inducing coagulopathy and endothelial dysfunction. Further research is needed to understand the mechanisms and develop interventions for COVID-19-related stroke.
Area of Science:
- Neurology
- Infectious Diseases
- Vascular Medicine
Background:
- COVID-19 is associated with diverse neurological complications.
- Stroke is a particularly severe neurological outcome observed in COVID-19 patients.
- Understanding the link between SARS-CoV-2 infection and stroke is critical.
Purpose of the Study:
- To review current literature on stroke in COVID-19 patients.
- To elucidate the current understanding of stroke mechanisms in this population.
- To highlight the impact on healthcare systems and stroke care.
Main Methods:
- Systematic review of studies, case series, and case reports.
- Focus on COVID-19 patients with stroke complications.
- Analysis of laboratory markers indicative of coagulopathy and endothelial dysfunction.
Main Results:
- SARS-CoV-2 infection leads to coagulopathy, evidenced by elevated D-dimer, fibrinogen, factor VIII, and von Willebrand factor.
- Endothelial dysfunction and a hypercoagulable state are promoted by the infection.
- These factors predispose COVID-19 patients to cerebrovascular events like stroke.
Conclusions:
- COVID-19 infection significantly increases the risk of stroke through mechanisms involving hypercoagulability and endothelial damage.
- The healthcare system's strain during the pandemic has compromised stroke care.
- Further investigation into the underlying mechanisms and development of therapeutic strategies for COVID-19-associated stroke are essential.
Abstract:
COVID-19 patients have presented with a wide range of neurological disorders, among which stroke is the most devastating. We have reviewed current studies, case series, and case reports with a focus on COVID-19 patients complicated with stroke, and presented the current understanding of stroke in this patient population. As evidenced by increased D-dimer, fibrinogen, factor VIII and von Willebrand factor, SARS-CoV-2 infection induces coagulopathy, disrupts endothelial function, and promotes hypercoagulative state. Collectively, it predisposes patients to cerebrovascular events. Additionally, due to the unprecedented strain on the healthcare system, stroke care has been inevitably compromised. The underlying mechanism between COVID-19 and stroke warrants further study, so does the development of an effective therapeutic or preventive intervention.

Regulation of Stroke Volume
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...
