Abstract
Background and purpose: COVID-19 is spreading throughout the whole world as a public health issue. There is a link between the new coronavirus and changes in biochemical indicators, such as coagulation functions. Hypercoagulable state of blood caused by infections may lead to cerebrovascular diseases. More attention should be paid to patients with COVID-19, especially critically ill individuals with history of cerebrovascular disease who may have high risk of stroke.
Methods: 193 patients with COVID-19 were enrolled in the study. These patients were categorized into nonsevere (143 patients) and severe (50 patients) groups. This study evaluated laboratory tests, including routine blood tests, C-reactive protein, erythrocyte sedimentation rate, electrolytes, and coagulation functions. Furthermore, neurological function and stroke risks were evaluated in this study.
Results: Compared to the nonsevere group, there were increases in white blood cells, neutrophil count, interleukin-6, erythrocyte sedimentation rate, and C-reactive protein in the severe group (p < .05). For coagulation functions, parameters like prothrombin time, international normalized ratio, activated partial thromboplastin time, thrombin time, D-dimer, and fibrin degradation products were increased significantly in the severe group (p < .01). Severe patients also demonstrated higher scores on the Framingham stroke risk profile and lower Glasgow scores (p < .05). Furthermore, significant associations were noticed between stroke risk and age, blood cell count, neutrophil count, D-dimmer, and fibrin degradation productions (p < .05).
Conclusions: Data suggested that coagulation functions were affected in patients with COVID-19. Hypercoagulable state in patients may lead to potential high risk of stroke.
Keywords: COVID-19; cerebrovascular disease; coagulation function; coronavirus; respiratory infection; stroke.
