| Abstract: | Objective To investigate the correlation between main pulmonary artery and right ventricular hypertrophy. Methods 60 patients with chronic obstructive pulmonary disease were randomly selected and examined with CT scan, under the electrocardiogram, ultrasound and divided into the right ventricular hypertrophy group (observation group) and no right ventricular hypertrophy group (control),30 patients for each. Main pulmonary artery diameter (MPAD) and ascending aorta diameter (AAD) were measured on the CT to calculate the ratio (MPAD/AAD). Results When the MPAD/AAD≤ 1.1, there was no significant difference between the two groups; while MPAD/AAD ＞ 1.1, the two groups were significantly different(P＜0.01); when the MPAD/AAD＞1.1, it predicts the sensitivity, specificity and positive predictive value of right ventricular hypertrophy were 86.7%, 96.7%, 96.3% respectively. Conclusion MPAD/AAD＞1.1 could be a new target for CT diagnosis to right ventricular hypertrophy. |
