Plasma Fibrinogen Level in Chronic Obstructive Pulmonary Disease and Its Correlation with GOLD Severity Staging

Results A total of 80 patients were enrolled. The mean age of the patient was 67.87±11.60 years. Plasma fibrinogen level was 159±12.72 mg/dl in mild COPD, 273.52±62.34 mg/dl in moderate COPD, 312.30±103.67 mg/dl in severe COPD, and 487±102.76 mg/dl in very severe COPD. The comparison between groups showed significant difference in plasma fibrinogen level (p<0.001). There was significant negative correlation between plasma fibrinogen level and forced expiratory volume in one second (FEV1%) predicted (r=-0.71, p=0.01). Conclusion High plasma fibrinogen level on discharge was found in COPD patients with severe airflow obstruction, frequent exacerbations and severe level of dyspnoea during AECOPD.
