Heart failure with preserved ejection fraction in people with COPD: clinical course and prognosis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study compares HFpEF detection rates in hospitalized COPD patients and examines how the presence of HFpEF affects clinical course and outcomes. Investigators will perform a retrospective chart review to identify previously undiagnosed HFpEF and compare recorded diagnoses with echocardiographic and hemodynamic criteria. Routine blood tests and biomarker analysis, echocardiography (including epicardial adipose tissue thickness and E/e'), spirometry, body plethysmography, and a 6‑minute walk test will be used to characterize participants. The study is conducted at sites in Kazan and Moscow and enrolls Russian citizens aged 50–70 hospitalized for COPD.
