Insights
Patients with acute ischemic stroke (AIS) and COVID-19 had similar rates of IV thrombolysis but lower mechanical thrombectomy rates and significantly higher in-hospital mortality compared to non-infected AIS patients.
Area of Science:
- Neurology
- Infectious Diseases
- Public Health
Background:
- The COVID-19 pandemic presents unique challenges for managing acute ischemic stroke (AIS).
- Understanding the interplay between AIS and SARS-CoV-2 infection is crucial for optimizing patient care.
- Comparing outcomes in AIS patients with and without COVID-19 can inform clinical and public health strategies.
Purpose of the Study:
- To compare healthcare parameters, treatment characteristics, and in-hospital mortality between AIS patients with and without concurrent COVID-19.
- To analyze nationwide data from Germany during the early phase of the pandemic.
Main Methods:
- Utilized a nationwide administrative database of hospitalized AIS patients from January 16th to May 15th, 2020.
- Included data from 1463 hospitals in Germany.
- Compared case numbers, intravenous thrombolysis (IVT), mechanical thrombectomy (MT), intensive care unit (ICU) or stroke unit treatment, and in-hospital mortality.
Main Results:
- Identified 213 AIS patients with concurrent COVID-19 among 30,864 COVID-19 patients.
- AIS patients with COVID-19 had similar IVT rates (16.4% vs. 16.5%) but significantly lower MT rates (3.8% vs. 7.9%) compared to 68,700 AIS patients without COVID-19.
- In-hospital mortality was significantly higher in AIS patients with COVID-19 (22.5%) versus those without (7.8%).
Conclusions:
- Nationwide data reveal distinct differences in mortality and treatment between AIS patients with and without COVID-19.
- AIS is a less common but frequently fatal comorbidity in COVID-19 patients.
- These findings underscore the need for vigilant management of AIS during the ongoing pandemic.
Background:
Comparing health care parameters of acute ischemic stroke (AIS) patients with and without concurrent coronavirus disease 2019 (Covid-19, SARS-CoV-2 infection), may be helpful in terms of optimizing clinical and public health care during pandemic.
Methods:
We evaluated a nationwide administrative database of all hospitalized patients with main diagnosis of acute ischemic stroke with/without diagnosis of Covid-19 who were hospitalized during the time period from January 16th to May 15th, 2020. Data from a total of 1463 hospitals in Germany were included. We compared case numbers, treatment characteristics (intravenous thrombolysis, IVT; mechanical thrombectomy, MT; treated on an intensive care unit, stroke unit or regular ward) and in-hospital mortality of AIS with and without concurrent diagnosis of Covid-19.
Results:
From a total of 30,864 hospitalized Covid-19 patients during the evaluation period in Germany, we identified a subgroup of 213 patients with primary diagnosis of AIS. Compared to the 68,700 AIS patients without Covid-19, this subgroup showed a similar rate of IVT (16.4% vs. 16.5%, p = 0.985) but a significantly lower rate of MT (3.8% vs. 7.9%, p = 0.017). In-hospital mortality rate was significantly higher in patients with AIS and concurrent Covid-19 compared to non-infected AIS patients (22.5% vs. 7.8%, p < 0.001).
Conclusion:
These nationwide data point out differences in mortality and medical treatment regime between AIS patients with and without concurrent Covid-19. Since the pandemic is still ongoing, these data draw attention to AIS as a less frequent but often fatal comorbidity in Covid-19 patients.
