摘要
理论依据肺动脉(PA)直径与主动脉比值(PA:A)是心血管成像中检测肺动脉高压的新标记。通过研究 PA:A 比值与主动脉直径之间的相关性,并比较 PA 直径、主动脉直径和 PA:A 比值之间的关联,我们对 PA:A 比值的可变性提出了质疑。方法我们纳入了鹿特丹研究中的 2197 名参与者,他们接受了非对比多载体计算机断层扫描,以测量 PA 和主动脉直径。计算了 PA:A 比值与主动脉直径之间的皮尔逊相关系数。结果我们发现 PA:A 比值与主动脉直径之间存在统计学意义上的显著相关性(r = -0.38,p <0.001)。PA 直径与身高、体重、舒张压、血压药物、心房颤动患病率、心力衰竭患病率和脑卒中患病率均有统计学意义(p < 0.05)。除血压药物外,PA:A 比值的决定因素与 PA 直径相似,但在统计学上与性别和收缩压显著相关(p < 0.05),而在统计学上与主动脉直径显著相关(p < 0.05)。
Revisiting the Clinical Interpretation of CT-Measured Pulmonary Artery-to-Aorta Ratio—The Rotterdam Study
Rationale
The pulmonary artery (PA) diameter-to-aorta ratio (PA:A) ratio is a novel marker in cardiovascular imaging for detecting pulmonary hypertension. However, we question the effect of the varying aorta diameter on the ratio, which complicates the interpretation of the PA:A ratio.
Objective
Investigate the variability of the PA:A ratio by examining the correlation between PA:A ratio and aorta diameter and by comparing the associations of the PA diameter, aorta diameters, and PA:A ratio.
Methods
We included 2197 participants from the Rotterdam Study who underwent non-contrast multidetector computed tomography to measure the PA and aorta diameters. Pearson correlation coefficient was calculated between the PA:A ratio and aorta diameter. Multiple linear regression analyses were performed to compare the determinants of the individual diameters and PA:A ratio.
Results
We found a statistically significant correlation between the PA:A ratio and aorta diameter (r = −0.38, p < 0.001). The PA diameter was statistically significantly associated with, height, weight, diastolic blood pressure, blood pressure medication, prevalence of atrial fibrillation, prevalence of heart failure, and prevalence of stroke (p < 0.05). Except for blood pressure medication, the PA:A ratio had similar determinants compared to the PA diameter but was also statistically significantly associated with sex, and systolic blood pressure (p < 0.05), which were statistically significantly associated with the aorta diameter (p < 0.05).
Conclusion
The PA:A ratio should not be interpreted without taking into account the variability of the individual components (PA and aorta diameter) according to the anthropomorphic and clinical characteristics.
