  • This study aims to investigate the correlation between the occurrence of colon polyps and carotid IMT by age. This study checked the correlation between the occurrence of colon polyps and carotid IMT, grouping patients who had a colonoscopy and carotid ultrasonography simultaneously by age based on cross-tabulation. As a result of the analysis, by age, the older the patients with metabolic syndrome, the higher the correlation between the occurrence of colon polyps and carotid IMT became. Also, when carotid IMT was more than 1.1mm, the incidence of polyps was high. In conclusion, there was a high correlation of the occurrence rate of colon polyps with carotid ultrasonography and colonoscopy, and the older the patient and the thicker the carotid IMT, the higher the correlation became.

  • B-모드 초음파를 이용한 경동맥 내중막 두께(IMT intima-media thickness) 측정은 관상동맥 질환이나 허혈성 뇌질환 위험도의 독립적인 인자로 매우 중요하다. 본 연구에서는 NTSC(national television system committee) 방식으로 경동씩 초음파 동영상신호를 획득하여 프레임으로 나누어 각각의 IMT를 측정하였다. 각각의 측정값을 시간축으로 재구성하여 시간도메인에서 IMT 의 시변동성을 분석하였다. IMT 시변동성 분석을 통하여 상대적으로 부정맥피험자가 정상피험자에 비해 IMT 평균값이 작아 위험도가 낮다고 평가 될 수 있지만 시변동성 분석으로 IMT 평균값이 작아도 혈관의 기능적 특징이 부족하여 위험도가 높다는 것을 알 수 있었다. 경동맥의 형태적 특징과 기능적 특징을 반영하는 이 분석방법은 경동맥 내중막 두께측정의 신뢰성을 향상시키며 관련질환의 위험도와 중증도를 세분화 할 수 있는 새로운 방법이 될 수 있을 것이다.

  • 경동맥 내중막두께(intima media thickness: IMT)는 2000년 미국심장학회에서 관상동맥 질환이나 허혈성 뇌질환 위험도의 독립적인 인자임을 인정하여 일차 진단지표로 권장함에 따라 세계적으로 그 관심이 확산되고 있다. 최근 국내에서도 서구화되어 가는 식생활 패턴으로 인해 고혈압, 동맥경화, 뇌졸중, 관상동맥 질환 등의 심뇌혈관계 질환 발병률이 높아지고 있다. 서구의 연구결과에 의하면 경동맥 내중막 두께는 인종, 성별, 연령에 따라 많은 차이를 보이기 때문에 임상적 진단에 기초가 되는 한국형 경동맥 내숭막두께 정상치 확립이 요구된다. 경동맥의 내중막두께는 경동맥 팽대부에서 근위부 10 mm 부위의 far wall 총경동맥 부위에서 심혈관계 위험 인자와 가장 상관성이 많은 것으로 보고되고 있다.

  • This study retrospectively analyzed the test results of 235 patients who visited a medical institution in Busan from May 2022 and February 2023 and conducted both carotid ultrasonography and blood tests. The purpose of this study was to investigate the effect on intima-media thickness and blood flow velocity by measuring the intima-media thickness and blood flow velocity through carotid ultrasonography and analyzing the factors influencing the subject's body mass index and metabolic syndrome. Correlation analysis between carotid intima-media thickness and body mass showed (p=0.000) confirming that there is a correlation. As a result Correlation analysis between blood flow velocity and body mass index (p=0.015) was found, comfirming that there was a correlation. Age (p= 0.000), fasting blood glucose (p=0.002) and alcohol consumption (p=0.006) were found to be correlated with carotid intima-media thickness. An increase in Carotid intima-media thicknesses causes an increase in events caused by cardiovascular disease. Therefore, efforts must be made to exclude factors that increase Carotid intima-media thicknesses, and it will be most important to prevent cardiovascular disease through research on various prediction methods and regular checkups.

  • Carotid Intima-Media Thickness (CIMT) testing is a test that precisely assesses cerebrovascular and coronary heart diseases. According to many previous studies, CIMT predicts atherosclerosis and is highly correlated to cardiovascular disease risk factors. It has also been reported that CIMT is an independent predictor of risk factors for myocardial infarction and stroke. Therefore, the purpose of this study is to investigate CIMT and other independent factors through a correlation study with the clinical laboratory test results of a blood test. As a result, this study could not prove the correlation between CIMT and risk factors of cardiovascular disease (TC, TG, LDL cholesterol, and HDL cholesterol) due to an insufficient number of subjects. Nevertheless, a positive correlation was demonstrated between CIMT and ALT (p<0.05), GGT (p<0.05), Uric acid (p<0.05), and CEA (p<0.05) at a statistically significant level, suggesting a continuation of the study.

  • It is reported that social distancing caused by the corona pandemic has resulted in a decrease in physical activity, and a decrease in muscle mass due to this increases the risk of vascular disease. Therefore, in this study, the risk of carotid intima media thickness was evaluated by measuring the thickness of CIMT, and the differences in variables according to gender were analyzed. From January 2022 to May 2022, a total of 220 people (121 males, 99 females) who performed blood tests, carotid ultrasound, and body composition analysis among those who visited the health check-up center of Busan H Hospital were included in this study. Significant differences in risk factors according to gender were analyzed using the chi-square test. The cut-off values of variables that can predict the risk of carotid intima media thickness were calculated, and the accuracy was evaluated by calculating the area under the curve, sensitivity, and specificity. As a result of the difference analysis, the higher the total cholesterol in men and the appendicular skeletal muscle index in women, the higher the risk of carotid intima media thickness. The cut-off value for predicting the risk of carotid intima media thickness was calculated to be greater than 199 mg/dL of total cholesterol in the male group and less than 5.9 kg/m2 of the appendicular skeletal muscle index in the female group. As a result of this study, the higher the total cholesterol in men and the lower the appendicular skeletal muscle index in women, the higher the risk of increased CIMT. Therefore, in women, the appendicular skeletal muscle index is expected to serve as an indicator to predict and prevent vascular changes at an early stage.

  • Arteriosclerosis is a disease in which blood circulation is impaired due to loss of elasticity as blood vessels become narrower, and is a potential cause of recently increasing cardiovascular and cerebrovascular diseases. Carotid ultrasound is used as a predictor of cardiovascular and cerebrovascular diseases by evaluating the degree of atherosclerosis. Therefore, this paper attempted to investigate the correlation between the increase in the thickness of the inner media and various clinical variables in carotid ultrasound. Patients with carotid ultrasound findings were classified into three stages: mild intima thickening, sclerosis, and significant stenosis. CAVI (Carotid Ankle Vascular Index: vascular age) data measured in the degree and physical characteristics of the carotid artery(gender, age, body mass index, blood pressure), blood test(total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, creatine phosphokinase, fasting blood sugar), and arteriosclerosis test were collected. It was confirmed that the carotid intima thickness was correlated with variables such as hypertension, hyperlipidemia, and BMI, and also correlated with the risk factors of cardiovascular disease as CAVI increased.

  • 심장질환과 혈관질환을 포함하는 심뇌혈관질환은 한국인 사망원인 1위이다. 대표적인 질환으로서의 뇌경색과 심근경색은 혈관이 막힌 후 6시간 이내에 뚫어주지 않으면 사망 또는 돌이킬 수 없는 상태에 이른다. 가족 중 이러한 환자가 있으면 환자가 사망할 때까지 수년간 환자 본인은 물론 가족 전체의 삶의 질이 크게 저하되며, 국내 심뇌혈관질환의 사회 경제적 비용은 5조 4천억원에 이른다. 따라서, 이와 같은 질환은 조기에 검출하는 것이 중요하다. 최근 경동맥 헐관벽 두께가 이러한 질환의 가능성과 상관성이 높다는 사실이 밝혀지면서 미국심장협회에서는 무증상이더라도 45세 이상이면 주기적으로 이 지표를 측정할 것을 권장함에 따라 이 분야의 연구가 전세계적으로 확산되고 있다. 본 연구에서는 경동맥의 내막과 중막 두께가 이러한 질환의 위험인자와 어떠한 상관성을 갖는지 밝힘으로써 궁극적으로는 삶의 질을 향상시키고자 한다.

  • In predicting vascular disease, this study attempted to identify changes in the carotid intima-media thickness in patients who underwent carotid artery ultrasonography and hematological tests and to find out the effect of risk factors on the expression of atherosclerotic plaque. A retrospective analysis was conducted on 469 healthy adults who visited the hospital for the purpose of medical examination and performed carotid artery ultrasonography. As a result, carotid intima-media thickness, age, body mass index, waist circumference, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and glucose were analyzed as significant predictors of atherosclerotic plaque (p<0.001). The risk ratio was calculated based on the cut off value of the risk factors of the atherosclerotic plaque determined through ROC curve analysis, followed by 8.06 times the carotid intima-media thickness, 7.53 times the age, 3.97 times the waist circumference and 2.02 times the glucose. Therefore, in this study it was possible to prepare a Korean standard for clinical risk factors that affect the presence of absence of atherosclerotic plaque and observation of carotid artery ultrasonography is thought to help diagnose or predict cardiovascular disease early.
