Abstract Pulmonary hypertension was previously considered a rare untreatable condition. The past two decades have seen major changes in our understanding of the spectrum of disease affecting the pulmonary circulation. More than 30 randomised controlled trials (RCTs) of treatments have been performed, and surgery for patients with chronic thromboembolic pulmonary hypertension has been developed. Advances in imaging have enabled more detailed patient assessment, but pulmonary hypertension continues to be a life shortening condition, and there is often a delay of around two years from onset of symptoms to diagnosis. In view of the above ,the present study was undertaken to assess the value of pulmonary artery diameter in CT chest , RVSP in echocardiography and MPI as an indicator for right ventricular function in pulmonary hypertension patients . The study included 50 patients, 24 males and 26 females ranging in age from 27 to 75 years who underwent CT chest and echocardiograghy The results obtained were collected ,tabulated , and submitted for statistical analysis The following results were obtained: 1) Among the 50 patients with PH , 19 patients had MPI >0.55 and 31 patients <0.55 2) A highly significant positive correlation was found between RVSP and pulmonary artery diameter in CT chest 3) Also there is a highly significant positive correlation between RVSP and MPI 4) The ratio between pulmonary artery diameter to aortic diameter (P/A) was correlated with RVSP and MPI 5) According to classification of PH , the comparison between 4 classified groups revealed more correlation of the study with CTEPH patients(71%) then with pulmonary arterial hypertension(56%) then with pulmonary hypertension with multifactorial mechanisms(33%) and lastly with pulmonary hypertension due to lung diseases and /or hypoxia(25%). 6) Pulmonary artery diameter was an indicator for pulmonary hypertension with a sensitivity 90 % using a cut off value 30 mm. |
