[PMID: 38013361 PMCID: PMC10681394 DOI: 10.1097/md.0000000000035502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 09/14/2023] [Indexed: 11/29/2023] Open
Abstract
OBJECTIVE Chronic obstructive pulmonary disease (COPD) is closely related to the development and progression of cardiovascular disease. The purpose of this study is to clarify the answers to the following questions through systematic evaluation: the risk of stroke in COPD patients; the risk of stroke in acute exacerbations of COPD (AECOPD) patients; and the risk of death after stroke in COPD patients. METHODS Two reviewers independently searched EMbase, PubMed, and the Cochrane Library for relevant literature from the date of creation to February 17, 2023, for studies relating COPD to stroke patients. Of the 8039 publications retrieved, we identified 27 articles that met our selection criteria. Fixed-effects or random-effects models were used to calculate ORs and 95% confidence intervals for the combined risk. RESULTS combining studies on stroke risk in COPD patients by random-effects model suggested that COPD was an independent risk factor for stroke-associated pneumonia (OR 1.40, 95% CI: 1.24-1.59, I2 = 98.4%, P = .000), with significant heterogeneity in the results, and subgroup analysis did not find a source of heterogeneity. In the combined 7 AECOPD studies, a significantly higher risk of stroke was found (OR 1.53, 95% CI: 1.44-1.63, I2 = 49.2%, P = .066). In the combined 6 short- term prognostic studies, the relationship between COPD and risk of death was not highly significant (OR 1.12, 95% CI: 1.08-1.16, I2 = 37.4%, P = .131). In 10 long-term observational prognosis studies, COPD was suggested to be associated with death after stroke by combining data using a random-effects model (OR 1.20, 95% CI: 1.13-1.27, I2 = 56.8%, P = .014), and there was moderate heterogeneity in the combination, with subgroup analysis showing that stroke type may be a source of heterogeneity and the risk of death from ischemic stroke: OR 1.23, 95% CI: 1.17-1.29, I2 = 45.0%, P = .191 and the risk of death from both types of stroke: OR 1.12, 95% CI: 1.07-1.18, I2 =18.9%, P = .291. CONCLUSION COPD is an independent risk factor for stroke. The risk of stroke is significantly increased, especially during AECOPD. In addition, the association between COPD and short-term death in stroke patients is insignificant, while it is more associated with fatal events in the long-term prognosis.

Influenza Vaccination and Risk of Stroke in Women With Chronic Obstructive Pulmonary Disease: A Nationwide, Population-Based, Propensity-Matched Cohort Study. Front Med (Lausanne) 2022; 9:811021. [PMID: 35665329 PMCID: PMC9160371 DOI: 10.3389/fmed.2022.811021] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 04/11/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundsThe risk of stroke is higher among patients with chronic obstructive pulmonary disease (COPD) than among the healthy population. Moreover, women generally have worse long-term stroke outcomes than men.MethodsThe data of 6681 women with COPD (aged ≥ 65 years) registered in Taiwan’s National Health Insurance Research Database were retrospectively analyzed from January 1, 2001 to December 31, 2011. After 1:1 propensity score matching, the patients were divided into vaccinated and unvaccinated groups.ResultsIn total, 5102 women were enrolled. The vaccinated group had a significantly lower risk of total, hemorrhagic, and ischemic stroke than the unvaccinated group (adjusted hazard ratio [aHR]: 0.60, 95% confidence interval [CI]: 0.54–0.67; aHR: 0.59, 95% CI: 0.43–0.83; and aHR: 0.59, 95% CI: 0.52–0.68, respectively). A lower risk of stroke was observed among the women aged 65–74 and ≥75 years, and the association was dose-dependent in all types of stroke (aHR: 1.08, 95% CI: 0.92–1.26; aHR: 0.70, 95% CI: 0.60–0.82; and aHR: 0.32, 95% CI: 0.26–0.38 for those vaccinated 1, 2 to 3, and ≥4 times, respectively, during the follow-up period). Women with a CHA2DS2-VASc score (conditions and characteristics included congestive heart failure, hypertension, diabetes, stroke, vascular disease, age, and sex) of 2–3 and ≥4 had a significantly lower risk of ischemic stroke while receiving more vaccinations. A smaller significant lower risk of hemorrhagic stroke after more than 4 times of vaccination was noted in the women with a CHA2DS2-VASc score of ≥4. Both interrupted and non-interrupted vaccination was associated with lower risk of stroke occurrence.ConclusionInfluenza vaccination is associated with a lower risk of total, hemorrhagic, and ischemic stroke among women with COPD, and the association is dose-dependent. However, the findings may be limited by unmeasurable confounders. Further investigations on this subject are warranted.

Abstract
Introduction: Research has shown that patients with ischemic stroke and coexisting obstructive respiratory disorders have worse clinical status on admission and increased long-term mortality. Patients with chronic obstructive pulmonary disease (COPD) are at increased risk of stroke, and the risk is even greater after exacerbation of COPD. Moreover, COPD and stroke share major risk factors, which are advancing age and smoking. The aim of this study was to analyze the incidence of complications and mortality in acute ischemic stroke (AIS) patients with and without COPD. Material and methods: We analyzed prospectively collected data of 1022 patients with acute is-chemic stroke hospitalized in a district general hospital. The patients were divided into two groups—with coexisting COPD and without COPD. Results: Logistic regression analysis, which allowed for potential confounders, showed an association between coexisting COPD and the fol-lowing complications in acute ischemic stroke patients: heart failure (OR = 1.879, p = 0.048), atrial fibrillation (OR = 4.746, p = 0.012), delirium (OR = 2.803, p < 0.001), pneumonia (OR = 2.424, p = 0.005), bronchospasm (OR = 3.400, p = 0.023), and out-hospital mortality (OR = 2.656, p = 0.001). Conclusion: Patients presenting with acute ischemic stroke and coexisting COPD significantly more often had cardiac and pulmonary complications, as well as delirium following stroke. In a long-term follow-up, the probability of one-year survival was significantly lower in AIS patients with co-existing COPD.

Front Neurol 2021; 12:723115. [PMID: 34867713 PMCID: PMC8634885 DOI: 10.3389/fneur.2021.723115] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Accepted: 10/12/2021] [Indexed: 02/05/2023] Open
Abstract
Background and Purpose: Chronic obstructive pulmonary disease (COPD) has been associated with several complications and mortality in acutely ill patients. For patients with aneurysmal subarachnoid hemorrhage (aSAH), the association between COPD and clinical outcomes remains unclear. Methods: In this retrospective cohort study, we analyzed consecutive aSAH patients admitted to the West China Hospital between 2014 and 2019. Propensity score matching analysis and cox regression models was used to assess the association between COPD and mortality. The primary outcome was long-term mortality. Results: Using a clinical database from a large university medical center, 2,925 patients with aSAH were identified, of whom 219 (7.5%) also had COPD. Patients were followed-up for a median of 3.8 years, and during follow-up 633 patients (21.6%) died. Long-term mortality was higher in patients with COPD compared to patients without COPD in the Cox regression models [adjusted hazard ratio (HR) 1.52, 95% confidence interval (CI) 1.14–2.02]. Propensity score matching analysis also showed similar associations between COPD and mortality in hospital, at 1 year, at 2 years, and at long-term. Similarly, patients with COPD had significantly higher incidence of infections, such as pneumonia [odds ratio (OR) 3.24, 95% CI 2.30–4.56], urinary tract infection (OR 1.81, 95% CI 1.20–2.73), bloodstream infection (OR 3.83, 95% CI 1.84–7.99), and hospital infection (OR 3.24, 95% CI 2.28–4.61). Conclusions: Among aSAH patients, COPD is associated with increased mortality. COPD represents a significant risk factor for infections. Given that these are preventable complications, our findings are of clinical relevance.
