Insights
The risk of deep vein thrombosis (DVT) in stroke patients increased during the COVID-19 pandemic. A new nomogram helps predict DVT risk in stroke patients during long-term COVID-19 management.
Area of Science:
- Neurology
- Cardiology
- Infectious Diseases
Background:
- Deep vein thrombosis (DVT) is a significant complication following stroke.
- The COVID-19 pandemic necessitates re-evaluation of DVT management in stroke patients.
- Understanding DVT risk factors during the COVID-19 era is crucial for long-term patient care.
Purpose of the Study:
- To assess the risk of DVT in stroke patients during the COVID-19 pandemic compared to pre-pandemic periods.
- To identify significant risk factors associated with DVT in stroke patients during COVID-19.
- To develop and validate a predictive nomogram for DVT in stroke patients during long-term COVID-19 management.
Main Methods:
- Retrospective analysis of 7087 stroke patients during the COVID-19 period and 14,174 matched patients from before the pandemic.
- Comparison of DVT incidence rates between the two periods.
- Statistical analysis to identify predictors of DVT and construction of a predictive nomogram with internal and external validation.
Main Results:
- The incidence of DVT in stroke patients was significantly higher during the COVID-19 period (20.5%) compared to the pre-pandemic period (15.9%).
- Key predictors of DVT included age, body mass index, smoking, D-dimer levels, physical activity, NIHSS score, and use of intermittent pneumatic compression.
- The developed nomogram demonstrated high accuracy and clinical applicability in predicting DVT risk.
Conclusions:
- Stroke patients faced an elevated risk of DVT during the COVID-19 pandemic.
- The established nomogram provides a valuable tool for assessing and predicting DVT risk in stroke patients during the ongoing management of COVID-19.
- Early DVT risk assessment and prevention strategies are essential for stroke survivors during the COVID-19 era.
Abstract:
Deep vein thrombosis (DVT) is an important complication of stroke. As coronavirus disease 2019 (COVID-19) enters the stage of persistent and long-term management, the clinical management of DVT in stroke patients may require adjustment. The present study evaluated whether there was an increased risk of DVT in stroke patients during the COVID-19 period. Furthermore, we analyzed the possible risk factors and developed an easy-to-use nomogram to predict DVT in stroke patients during the long-term management of COVID-19. A total of 7087 stroke patients during the COVID-19 period and 14,174 patients with age, sex, and National Institutes of Health Stroke Scale (NIHSS) scores matched before the period from four centers were included. The incidence of DVT in stroke patients during the COVID-19 period (20.5%) was significantly higher than that before this period (15.9%, P < .001). Age, body mass index, smoking, D-dimer, physical activity level, NIHSS score, and intermittent pneumatic compression were significant predictors of DVT during the COVID-19 period (P < .05). A nomogram was constructed; internal and external validations showed high accuracy, and decision curve analysis showed excellent clinical applicability. This nomogram could evaluate the risk of DVT after stroke and assist in its early prevention during the long-term management of COVID-19.
