The Prognostic Value of Cardiopulmonary Exercise Testing Parameters in Patients With Coronary Heart Disease: A Retrospective Cohort Study(CPETPCAD)

Parameters related to cardiopulmonary exercise testing (CPET) are important objective indicators for evaluating cardiopulmonary function in patients with coronary heart disease. However, the clinical application of CPET parameters in the prognostic assessment of patients with coronary heart disease remains unclear. This is a retrospective cohort study designed to systematically collect real-world clinical data and long-term follow-up outcomes of patients with coronary heart disease. Through standardized follow-up, this study will investigate the association between CPET parameters and adverse clinical outcomes in patients with coronary heart disease, as well as the relevant risk factors.
