Evaluation of the impact of cardiopulmonary rehabilitation exercise training on cardiopulmonary function in patients with chronic obstructive pulmonary disease complicated by unstable angina pectoris using a hierarchical deep learning CT image model

CPR not only substantially improves clinical cardiopulmonary function but also induces beneficial structural remodeling of the lung parenchyma, airways, pulmonary vasculature, and heart in patients with COPD complicated by UA pectoris. The DL-based CT image quantification framework provides reliable imaging biomarkers for objectively evaluating rehabilitation efficacy in these comorbid patients, offering new evidence for personalized management of cardiopulmonary comorbidities.
