However, when spirometry was restricted to prevent cross-infection such as COVID-19 pandemic, a modified index would be needed. Because cardiovascular dysfunction is associated with poor clinical outcomes in COPD, we conducted a novel BHDE-index by replacing spirometry with post-exercise heart rate recovery (HRR, H) and evaluated its predictive performance in this observational study.enChronic obstructive pulmonary disease; Heart rate recovery; Pulmonary function; Pulmonary rehabilitation[SDGs]SDG3journal article10.1186/s12890-023-02557-7374610732-s2.0-85165113029https://api.elsevier.com/content/abstract/scopus_id/85165113029
