The role and utility of equilibrium radionuclide angiocardiography was estimated in non-invasive diagnosis of patients with Chronic Obstructive Pulmonary Disease (COPD). In 26 healthy subjects the average value of Right Ventricular Ejection Fraction (RVEF) was 54.8 +/- 7.2, versus 40.89 +/- 7.85 in 37 patients with COPD. Right heart catheterization was performed on 9 patients with COPD, randomly chosen, to analyze the correlation between RVEF values and average Pulmonary Artery Pressure (PAP) values: the correlation index was significantly high (r = 0.80). Moreover, an important agreement was observed between RVEF and PaCO2 values (r = 0.77).
在慢性阻塞性肺疾病（COPD）患者的无创诊断中，评估了平衡放射性核素心血管造影的作用和效用。26名健康受试者的右心室射血分数（RVEF）平均值为54.8±7.2，而37名COPD患者的该值为40.89±7.85。随机选择9名COPD患者进行右心导管插入术，以分析RVEF值与平均肺动脉压（PAP）值之间的相关性：相关指数显著较高（r = 0.80）。此外，还观察到RVEF与PaCO2值之间存在重要相关性（r = 0.77）。
