Objectives: Autonomic dysfunction (AD) and dynamic hyperinflation (DH) have been implicated as pathophysiological mechanisms of heart failure with preserved ejection fraction (HFpEF) in chronic obstructive pulmonary disease COPD) patients. Their association, however, remains elusive: The aims of the study were: (1) to determine the prevalence of AD and DH in non-severe COPD patients, with exertional dyspnea, without clinically overt cardio-vascular (CV) comorbidities; (2) to analyze the correlation and clinical significance between DH, AD, and maksed HFpEF.

Methods: We applied CPET in 68 subjects.

Article Synopsis
  • The study aimed to determine if combining exercise stress echocardiography and cardio-pulmonary testing can help diagnose early left ventricular diastolic dysfunction (LVDD) in patients with mild chronic obstructive pulmonary disease (COPD) and exercise-related breathing difficulties.
  • Conducted with 104 non-severe COPD patients, the research found that 64% exhibited stress-induced LVDD during testing, characterized by lower exercise capacity and efficiency.
  • The results suggest that the combined testing can identify hidden LVDD in these patients, but the cardio-pulmonary testing measures did not predict the presence of LVDD.
