Abstract

This study examined 202 patients who was diagnosed as arteriosclerosis obliterans around carotid artery caused by its increase in IMT and who have been tested by carotid artery sonography. The results are as follows : 1. Out of 202 research subjects, 120(59.4%) were male, 82(40.6%) female, and the average age was 58. 2. Among the subjects, 54(26.7%) were diagnosed as DM, 60(29.7%) with hyperlipidemia, 86(42.6%) with hypertension, 61(30.2%) with EGK. 3. There was more increase in the left IMT than in the right IMT, more increase in male subjects than female subjects, and more increase with age. 4. The relationship between IMT & MRA was that subjects tested by MRA showed greater statistically significant correlation than those not tested by MRA(p < 0.01). 5. The increase in IMT was correlated with DM and HTN, but not with EKG and hyperlipidemia. 6. Among subjects tested by MRA, those diagnosed with MCA stenosis showed increase upto 0.94 in the left IMT and 0.96 in the right IMT ; there was a significant correlation(p < 0.01). Thicker IMT was positively correlated with diagnosis of MCA stenosis after MRA test.

본 연구에서는 경동맥 주위에 경동맥 내막-중막 두께(IMT) 증가로 발생하는 동맥경화성 폐색증을 알아보고, 경동맥 초음파 검사를 실시한 202명의 대상으로 다음과 같은 결론을 얻었다. 1. 연구 대상자 202명의 일반적 특징은 남자가 120명(59.4%), 여자가 82명(40.6%)이었으며, 평균 연령은 58세였다. 2. 전체 대상자 중 당뇨(DM) 54명(26.7%), 고지혈증(Hyperlipidemia)은 60명(29.7%), 고혈압(Hypertension) 86명(42.6%), 심전도(EKG) 61명(30.2%)으로 나타났다. 3. IMT는 Left IMT가 Right IMT보다 두께가 증가하였으며, 남성이 여성보다 IMT가 두꺼워졌고, 연령이 증가할수록 IMT가 더 증가하였다. 4. IMT & MRA와의 관계는 MRA을 시행한 115명은 검사하지 않은 87명 보다 IMT 두께와의 상관관계가 있는 것으로 나타났다(p < 0.01). 5. IMT가 증가할수록 DM, HTN와의 상관관계가 나타났으며, EKG(심전도) Hyperlipidemia(고지혈증)은 상관관계가 없는 것으로 나타났다. 6. MRA을 시행한 115명의 환자에서 MCA의 협착이 있는 군은 Left, Right IMT가 0.94 mm, 0.96 mm으로 두께가 증가되어 p < 0.01로 상관관계가 있는 것으로 나타났으며, IMT가 두꺼울수록 MRA를 실시한 후 MCA에서 동맥 협착(stenosis)으로 나타났다.
