The influencing factors of chronic obstructive pulmonary disease concomitant with pulmonary heart disease and the diagnostic value of myocardial markers

PAP, ICOSL, cTnI, CK-MB, and NT proBNP were all independent risk factors relating to the occurrence of COPD concomitant with PHD. The combined detection of cTnI, CK-MB, and NT-proBNP had certain diagnostic reference value for COPD concomitant with PHD. Monitoring these myocardial markers may provide clues for early identification of patients with COPD concomitant with PHD and assist in the clinical development of targeted intervention programs.
