Insights
COVID-19 patients with cardio-cerebrovascular disease face a significantly higher risk of severe illness and death. This meta-analysis confirms a strong association, highlighting the need for focused nursing care for these vulnerable individuals.
Area of Science:
- Cardiology
- Neurology
- Infectious Diseases
- Public Health
Background:
- COVID-19 pandemic has highlighted the impact of comorbidities on patient outcomes.
- Diabetes and hypertension are known to worsen COVID-19 severity.
- The effect of cardio-cerebrovascular disease on COVID-19 prognosis remained unclear.
Purpose of the Study:
- To conduct a meta-analysis evaluating the association between cardio-cerebrovascular disease and COVID-19 severity and mortality.
- To compare the impact of cardiovascular versus cerebrovascular disease on COVID-19 outcomes.
Main Methods:
- Systematic literature search of PubMed, Web of Science, and CNKI databases up to July 25.
- Random-effect model meta-analysis to calculate overall odds ratios (OR) with 95% confidence intervals (CIs).
- Publication bias assessed using funnel plots and Begg's/Egger's tests.
Main Results:
- Thirty-one studies including 23,632 patients were analyzed.
- Cardio-cerebrovascular disease was associated with increased COVID-19 severity (OR = 3.004) and mortality (OR = 5.587).
- Cerebrovascular disease showed a stronger association with increased severity (OR = 3.400) and mortality (OR = 23.477) compared to cardiovascular disease.
Conclusions:
- Cardio-cerebrovascular disease is a significant risk factor for severe illness and death in COVID-19 patients.
- Cerebrovascular disease poses a greater risk than cardiovascular disease for adverse COVID-19 outcomes.
- Healthcare providers, particularly nurses, should prioritize monitoring and care for COVID-19 patients with cardio-cerebrovascular conditions.
Abstract:
At present, COVID-19 is raging all over the world. Many comorbidities, such as diabetes mellitus (OR = 2.67, 95% CI = 1.91-3.74) and hypertension (OR = 2.3, 95% CI = 1.76-3.00), have been shown to worsen the patient's condition. However, whether cardio-cerebrovascular disease will affect COVID-19 remains unclear. In this meta-analysis, we collected studies from PubMed, Wed of Science and CNKI (Chinese) to July 25, which reported COVID-19 patients with and without cardio-cerebrovascular disease as well as their severity and mortality. The random-effect model meta-analysis was used to analyze them and get overall odds ratios (OR) with 95% CIs. Funnel plots and the Begg's and Egger's test were used to assess publication bias. Thirty-one studies with 23,632 patients were finally included in the meta-analysis. The results showed an OR of 3.004 (95% CI = 2.097-4.303) for COVID-19 severity and an OR of 5.587 (95% CI = 2.810-11.112) for COVID-19 mortality. Compared with cardiovascular disease, the subgroup analysis indicated that cerebrovascular disease was more likely to increase the severity (OR = 3.400, 95% CI = 1.569-7.368) and mortality (OR = 23.477, 95% CI = 3.050-180.735) of COVID-19. Therefore, it can be inferred that cardio-cerebrovascular disease is associated with an increase in the risk of severe illness and death among COVID-19 patients. This meta-analysis showed that cardio-cerebrovascular disease has a significant relation with severe and death outcomes of COVID-19. Nurses should pay special attention to COVID-19 patients with the cardio-cerebrovascular disease.
