Unveiling MicroRNA-21 as a non-invasive diagnostic biomarker in chronic obstructive pulmonary disease-associated pulmonary hypertension: Comparative insights with NT-proBNP

Key Points

• To assess the effectiveness of miR-21 as a diagnostic biomarker for pulmonary hypertension in COPD patients.
• Comparative analysis of miR-21 and NT-proBNP levels in COPD patients.
• Evaluation of miR-21's diagnostic accuracy for pulmonary hypertension.
• miR-21 showed greater reliability as a biomarker compared to NT-proBNP.
• MicroRNA-21 was identified as a potential non-invasive diagnostic tool for pulmonary hypertension.
