Researchers are investigating the prevalence, disease burden, and prognosis of chronic obstructive pulmonary disease (COPD) in patients aged 40 years or older with three types of cardiovascular diseases (CVD): coronary heart disease (CHD), atrial fibrillation (AF), and chronic heart failure (CHF). This multi-center, prospective, and interventional study aims to describe how common COPD is among these CVD patients and to observe how combined cardiopulmonary management affects their short-term prognosis. The study plans to enroll approximately 3,000 subjects, divided evenly among the three disease cohorts. The study involves a guideline education and implementation intervention delivered at both the investigator and patient levels. Investigators will receive education about COPD and CVD about four weeks before enrolling subjects. After enrollment, cardiologists and pulmonologists will provide patients with disease education every four weeks and collaborate on treatment management. Participants will be followed up every four weeks throughout the study period to monitor their health and treatment progress. Participants will undergo assessments including spirometry testing and questionnaires evaluated by investigators to confirm cognitive ability. Researchers will measure the number and percentage of COPD cases among subjects with CVD at baseline. Follow-up visits every four weeks will support ongoing treatment management and monitoring. The study duration and detailed timelines align with the intervention and follow-up schedules, ensuring comprehensive observation of patient outcomes and safety.
