Objective:
To investigate the relationship between the plasma adrenomedullin (ADM) levels and the extent of chronic cor-pulmonale and its underlying diseases, and explore the role of ADM in these diseases.
Methods:
Totally 26 patients with chronic bronchitis, chronic bronchitis accompanied with obstructive pneumonectasia or chronic cor-pulmonale were included respectively as clinical test group T1, T2 and T3; 26 normal people and 14 patients with pneumonia were chosen as control groups (group C1 and C2). Plasma concentration of ADM in every selected individual had been measured with specific radioimmunoassay.
Results:
Levels of plasma ADM in T3 were significantly higher than those in T2, and T2 than T1, C1 and C2 (P < 0.05), but there were no obvious difference between T1 and C1, between T1 and C2 (P > 0.05).
Conclusions:
Plasma ADM levels can reflect the severity of the above series of diseases.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
