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.
Our hospital has diagnosed coronary heart disease and conducted cardiopulmonary exercise tests.
Patients with complete clinical data.
Uncontrolled heart failure (NYHA classification Ⅲ-IV grade).
Complications, such as moderate to severe anemia, tumors and lung diseases.
Complicated with valvular heart disease.
Unable to reach the anaerobic threshold during exercise.
Patients diagnosed with coronary heart disease in our hospital and who have completed cardiopulmonary exercise testing.
