Impacts of COPD exacerbation history on mortality and severe cardiovascular events among patients with COPD in China: a retrospective cohort study

This study found that severe COPD exacerbations significantly increased mortality risk in Chinese patients with COPD. Patients with a history of severe exacerbations also reported a higher incidence rate of severe cardiovascular events. These findings emphasize the need for improved exacerbation prevention strategies in COPD management.
