Cacium scoring과 허혈성 심장질환 유병률과의 관계

Relation of Calcium scoring and prevalence rate of Ischemic heart disease

Purpose Purpose of this study is to know relative relation between Calcium scoring and prevalence rate of Ischemic heart disease, therefore it was divide the dangerous degree, using calcified material Risk classified list in Calcium scoring test. Materials and Methods Chest CT( Cardiac a) underwent from November, 2006 January, 2007. T-score at Calcium scoring examination did 214 (36.58 %) who Test more than 0.1 by target except young child patient, Calcium scoring is a patient who was 0 that have been ever enforced heart and Percutaneous Coronary Intervention(PCI) among 585 patient that is prescribed Chest CT(Cardiac A). Target patient man 115 people (53.7 %), average age 63.2 and woman 99 people(46.3 %), average age 65.8. T-score value that score is gotten by Calcium scoring scan classify, (1)group when it is below 100, 100 to 400 (2)group, and 400 to 1000 (3)group, and more than 1000 to (4)group. And analyzed by back to front about relation of Calcium scoring and ischemic heart disease divides and examined by each LM, LAD, LCX, RCA and compares interpretation sequence with each Coronary arteries T-score value after post enhancement CT scan and find Coronary artery stenosis or Perfusion Defect. Results Calcium score appeared highest by 23,110.5 in LAD and ranged in RCA (18, 996.4), LCX (7, 360.6), LM (3, 412.3) order. Also, when was expose in LAD as Stenosis position distribution chart calcium score’s result, RCA, LCX, LM order and it is 36.6% when is (4)group perfusion defect probability (4)group, and it is 26.3% when is (3)group, it is when is 10% (2)group, it is when is 5.2% (1)group. Conclusion When the Calcium score and ischemic heart disease that analyze data on the basis of diagnostic results, it could know that possibility is high to cause ischemic heart disease, if calcium score was high. Considering these results, position of abnormality or other details information was not agree correctly, It is Calcium scoring scan not only screening test, but also meaning of independent test.
