From: NOX4 expression and distal arteriolar remodeling correlate with pulmonary hypertension in COPD
Ventricular dimensions and pulmonary circulation parameters on cMRI. (a) Representative images of cMRI movie showed the main pulmonary artery and ventricle. (a) A main pulmonary artery FIESTA short axis image of non-COPD patients; (b) a main pulmonary artery FIESTA short axis image of COPD patients; (c) a main pulmonary artery vertical position image of non-COPD patients; (d) a main pulmonary artery vertical position image of COPD patients; (e) a left and right ventricle short axis image of non-COPD patients; (f) a left and right ventricle short axis image of COPD patients. (b-e) Correlations between pulmonary artery parameters and pulmonary functions. (b) Correlation between mPAD and FEV1/FVC; (c) correlation between mPAD and FEV1%pred: (d) correlation between RVMED and PO2; (e) correlation between RVMED and PCO2. PA: main pulmonary artery; REMED: right ventricular myocardial mass end diastolic; RV: right ventricle; LV: left ventricle; mPAD%: the main pulmonary artery distensibility; PO2: arterial partial pressure of oxygen; PCO2: partial pressure of carbon dioxide; FEV1/FVC: forced expiratory volume in one second/forced vital capacity; FEV1%pred: forced expiratory volume in one second total predicted value
