Insights
Severe COVID-19 increases cerebrovascular event risk, especially with comorbidities. Elevated inflammatory markers like C-reactive protein and D-dimer indicate a "cytokine storm" in patients with acute cerebrovascular events.
Area of Science:
- Neurology
- Infectious Diseases
- Cardiology
Background:
- The novel Coronavirus disease (COVID-19) is linked to a higher risk of cerebrovascular events.
- A significant number of severe COVID-19 cases present with acute cerebrovascular events.
Purpose of the Study:
- To determine the prevalence of acute cerebrovascular events in hospitalized severe COVID-19 patients.
- To identify inflammatory markers associated with COVID-19 infection in these patients.
Main Methods:
- Retrospective review of 1,228 severe COVID-19 patients admitted to West Kazakhstan Medical University Hospital.
- Diagnosis of COVID-19 via nasopharyngeal PCR, blood count, inflammatory markers, and chest CT.
- Diagnosis of acute cerebrovascular events based on clinical manifestation.
Main Results:
- 1.22% (N=15) of severe COVID-19 patients were diagnosed with acute cerebrovascular events.
- The mean age was 66.9 years; 53% were male.
- Comorbidities were common: hypertension (87%), coronary heart disease (47%), diabetes mellitus (33%).
- Elevated inflammatory markers were prevalent: C-reactive protein (100%), D-dimer (87%), ferritin (60%), and interleukin-6 (60%).
Conclusions:
- SARS-CoV-2 infection triggers a systemic inflammatory response, increasing cerebrovascular event risk in COVID-19 patients, particularly those with comorbidities.
- Elevated inflammatory markers support the
Abstract:
The novel Coronavirus disease (COVID-19) is associated with an increased risk of cerebrovascular events. About 1,228 cases of severe COVID-19 were hospitalized in the West Kazakhstan Medical University Hospital, in Aktobe, Kazakhstan, 1.22% (N=15) of whom were clinically diagnosed with acute cerebrovascular events and were included in the current study. COVID-19 was diagnosed using a nasopharyngeal polymerase chain reaction (PCR) test, blood count, inflammatory markers, and chest computerized tomography. The diagnosis of acute cerebrovascular events was based on the clinical manifestation. The participants' data were reviewed to detect the prevalence of acute cerebrovascular events and the inflammatory markers associated with COVID-19 infection. The mean age of the participants was 66.9 years (±11.07), 53% (N=8) of them were male, while 47% (N=7) were female. Moreover, 13% (N=2) presented a history of cerebrovascular events, 87% (N=13) of the participants had hypertension, 47% (N=7) had coronary heart disease, 33% (N=5) had diabetes mellitus (DM), 13% (N=2) had cardiac arrhythmia, and 13% (N=2) had chronic obstructive pulmonary disease (COPD). The C-reactive protein was high in 100% (N=15) of participants, D-dimer in 87% (N=13) of them, and both the ferritin and interleukin-6 were high in 60% (N=9) of the participants. SARS-CoV-2 causes a systemic inflammatory response, and the presence of comorbidities increases the risk of acute cerebrovascular events in COVID-19-infected individuals. The elevated inflammatory markers in severely COVID-19-infected individuals support the inflammatory "cytokine storm" response theory.
