Beta-blockers reduced the risk of mortality and exacerbation in patients with COPD: a meta-analysis of observational studies.

ABSTRACT:

Background

Cardiovascular disease is a primary cause of death in patients with chronic obstructive pulmonary disease (COPD). Beta-blockers have been proved to reduce morbidity and improve survival in patients with cardiac diseases. But the effects of beta-blockers on outcomes in patients with COPD remain controversial. The objective of this meta-analysis was to assess the effect of beta-blockers on mortality and exacerbation in patients with COPD.

Methods

An extensive search of the EMBASE, MEDLINE and Cochrane was performed to retrieve the studies of beta-blockers treatment in patients with COPD. The random effects model meta-analysis was used to evaluate effect on overall mortality and exacerbation of COPD.

Results

Fifteen original observational cohort studies with a follow-up time from 1 to 7.2 years were included. The results revealed that beta-blockers treatment significantly decreased the risk of overall mortality and exacerbation of COPD. The relative risk (RR) for overall mortality was 0.72 (0.63 to 0.83), and for exacerbation of COPD was 0.63 (0.57 to 0.71). In subgroup analysis of COPD patients with coronary heart disease or heart failure, the risk for overall mortality was 0.64 (0.54-0.76) and 0.74 (0.58-0.93), respectively.

Conclusion

The findings of this meta-analysis confirmed that beta-blocker use in patients with COPD may not only decrease the risk of overall mortality but also reduce the risk of exacerbation of COPD. Beta-blocker prescription for cardiovascular diseases needs to improve in COPD patients.

Project description:ObjectiveTo compare the clinical features and outcomes in patients with pre-chronic obstructive pulmonary disease (COPD) and COPD hospitalised for confirmed or suspected acute exacerbation of COPD (AECOPD).DesignA multicentre, longitudinal observational cohort study.SettingData were obtained from the AECOPD Inpatient Registry Study in China.Participants5896 patients hospitalised for AECOPD between 2017 and 2021.OutcomesPatients were divided into the COPD (n=5201) and pre-COPD (n=695) groups according to the lung function test results. The outcomes of interest included all-cause, respiratory disease-related and cardiovascular disease-related deaths as well as readmissions within 30 days and 12 months after discharge. Cumulative incidence functions were used to estimate the risk of cause-specific mortality and readmission. Multivariate hazard function models were used to determine the association between lung function and outcomes.ResultsThere were significant between-group differences in the symptoms at admission and medication use during hospitalisation. However, there was no significant between-group difference in the 30-day all-cause mortality (0.00 vs 2.23/1000 person-month (pm), p=0.6110) and readmission (33.52 vs 30.64/1000 pm, p=0.7175). Likewise, the 30-day and 12-month cause-specific outcomes were not significantly different between groups (30-day readmission with acute exacerbation (AE): 26.07 vs 25.11/1000 pm; 12-month all-cause mortality: 0.20 vs 0.93/1000 pm; all-cause readmission: 11.49 vs 13.75/1000 pm; readmission with AE: 9.15 vs 11.64/1000 pm, p>0.05 for all comparisons). Cumulative incidence curves revealed no significant between-group differences in the 30-day and 12-month prognosis (p>0.05). Multivariate analysis revealed no significant association of lung function categories with 30-day and 12-month mortality or readmission (p>0.05 for all effect estimations).ConclusionsPatients with pre-COPD have mild symptoms and similar risks for mortality and readmission during follow-up as patients with COPD. Patients with pre-COPD should receive optimal therapies before the occurrence of irreversible damage.
