Frequency of Ectasia among Patients with Coronary Atherosclerosis by Angiography Dual Source & 64 CT SLICE Evaluatin

Introduction: The aim of this study is Frequency of ectasia among patients with coronary atherosclerosis. Materials and Methods: This is a cross-sectional study, which retrospectively had evaluated a percentage of total frequency ectasia among patients with coronary atherosclerosis by angiography Dual a source & 64 CT SLICE between 2007-20012 in Imag Center of Imam Khomeini Hospital and shahid Rajai Hospital. Results: Totally 2770 patients were enrolled in the study. The frequency of ectasia among all patients was 42 [1.5%]. The frequency of stenosis in patients with LAD ectasia was 36.8% [7 out of 19] while the frequency of LAD stenosis in other patients was 59.5% [1637 out of 2751] [P=0.045]. Distribution of stenosis in ecstatic LCx and RCA was not statistically different with patients without non ecstatic LCx and RCA. [P=0.47 and 0.45 respectively]. In patients with ectasia, the frequency of stenosis was 71.4 while it was 64.4% in patients without ectasia [P=0.35]. Discussion: Furthermore, detection and investigation of Ectasia in patients with stenosis will lead to more accurate determination of the treatment plan and the purpose of this study is finging a new assess prevalence of morphological changes Ectasia by CT angiography and coronary sclerosing Prevalence this group of patients.
