Purpose: The purpose of this study is to establish guidelines for ankle-brachial index (ABI), toe-brachial index (TBI) and toe pressure with regard to healing of diabetic foot amputation wound. Material and Methods: We designed a retrospective study that included patients with diabetic foot ulcer. From 2008 to 2011, 46 patients who had suffered from amputation of a foot due to diabetic foot ulcer were included in this study. We divided them into amputation-success group and amputation-revision group, and compared their ankle-brachial index (ABI), toe-brachial index (TBI) and toe pressure between two groups. Amputation-revision group is that first forefoot amputation is failed to heal successfully and need to have another proximal amputation. Results: Toe pressure was 78 mmHg (54~107) in the amputation success group, 0 mmHg (0~43) in the amputation revision group (p=0.000). Ankle-brachial index was 1.1650(1.0475~1.1975) in the amputation success group, 0.92(0.5275~1.0750) in the amputation revision group (p=0.05), and toe-brachial index was 0.6100(0.4050~0.7575) in the amputation success group, 0.00(0.00~0.4150) in the amputation revision group (p=0.04), respectively. Conclusion: ABI, TBI, toe pressure of amputation success group were significantly higher than those of amputation revision group.

Objectives: The cardio-ankle vascular index (CAVI) and ankle-brachial index (ABI) are non-invasive methods to evaluate cardiovascular disease and arteriosclerosis. This study investigated the relationship between CAVI, ABI, and factors related to arteriosclerosis. Methods: This study included 535 healthy adults who underwent health examinations in 2019. We analyzed the correlation between CAVI, ABI and clinical variables. Multiple regression analysis was performed on the independent clinical variables associated with CAVI and ABI. Results: The correlation analysis of CAVI showed that body mass index (BMI) and HDL-cholesterol (HDL-C) had a negative correlation, and the other variables had a significant positive correlation. The correlation analysis with ABI on the right side showed that age, diastolic blood pressure (DBP), gender, and LDL-cholesterol (LDL-C) had a significant positive correlation, while HDL-C had a significant negative correlation. There was no statistical significance on the left. In the multiple regression analysis, DBP, age, BMI, gender, and HDL-C were proved to be independent factors in CAVI (right) (R²=0.365); DBP, age, gender, BMI, fasting blood sugar, and total cholesterol in CAVI (left) (R²=0.357); and age, gender, DBP, and systolic blood pressure in ABI (right) (R²=0.133). There were no statistically significant factors in ABI (left). It could be inferred that smoking and drinking are determinants that play an important role in CAVI. Conclusion: CAVI showed a high correlation with gender, age, and blood pressure. A significant correlation between CAVI and serum lipid values could be observed, but this showed a low correlation coefficient. ABI showed a high correlation with age and DBP. These results support the use of CAVI and ABI as primary diagnostic devices in medical treatment.

Background : The ankle brachial pressure index (ABI) is a simple, useful method for diagnosing peripheral artery disease (PAD). Although the ABI is an objective diagnostic method, it has limited reliability in certain scenarios. The aim of the present study was to determine the accuracy and reliability of the toe brachial index (TBI) as a diagnostic tool for detecting stenosis in PAD, associated with normal or low ABI values. Methods : ABI and TBI values were measured in 15 patients with diabetic gangrene who were suspected of having lower extremity arterial insufficiency. The ABI and TBI values were measured using a device that allowed the simultaneous measurement of systolic blood pressure in the upper and lower extremities. In addition, the ABI and TBI values were compared pre- and post-angiography. Results : Patients with an ABI of 0.9-1.3 showed almost no difference between the 2 measurements. The patients with TBI >0.6 had no arterial insufficiency. The patients with TBI <0.6 required vascular intervention with ballooning. After the angiography, the gangrenous wounds decreased in size more rapidly than they did prior to the intervention. Conclusions : Our findings suggest that TBI is the method of choice for evaluating lower limb perfusion disorders. This result requires further studies of TBI in a larger number of patients. Future long-term studies should therefore evaluate the utility of TBI as a means of screening for PAD and the present findings should be regarded as preliminary outcomes.

본 연구는 심혈관 질환자의 발목-상완 지수(ankle-brachial index, ABI)에 따른 심혈관 질환 중증도를 분석하여 ABI의 임상적 유용성을 확인하기 위함이다. 연구 대상자는 일개 종합병원의 ABI를 측정한 심장내과 환자 441명 이었으며, 전자 의무 기록을 통해 ABI와 심혈관 질환 중증도를 나타내는 vessel disease 및 Gensini score를 조사하였다. 수집된 자료는 SPSS 21.0을 이용하여 분석하였다. ABI 0.90 이하인 비정상군과 0.90 초과인 정상군으로 나누어 비교하였을 때, vessel disease 분포 비율의 차이가 있었다($x^2=4.731$, p=.030). ABI 두 군과 Gensini score에 대한 비교분석에서 비정상군 $39.1{\pm}32.7$점, 정상군 $27.4{\pm}27.4$점으로 유의한 차이가 있었다(t=2.351, p=.019). 본 연구의 결과에서 ABI 비정상군이 중증도 높은 심혈관 질환자들의 분포가 많았으며, 평균 Gensini score도 높은 것을 확인할 수 있었다. 따라서 ABI를 시행하는 것은 비침습적인 방법으로 중증도 높은 심혈관 질환자를 예측하는데 도움이 되어 허혈성 심장 질환의 조기 발견에 유용하게 활용 가능할 것으로 기대된다.

In this paper, Finger-Toe Index (FTI) is proposed as an analytic parameter for the characterization of arterial vessel. Different from the currently being employed pulse wave velocity (PWV) information of the volume pulse wave measured from 4 arterial channels, the proposed FTI uses the ratio of the shorter of the two up-stroke time of PPG from fingers ($UT_{finger}$) and that of PPG (Photoplethysmography) from toes ($UT_{toe}$). To verify the usefulness of the proposed method, Finger-Toe Indexes were derived from the volume pulse waves acquired from 50 people under examination aged from 12 to 81 years old, and they were then compared with blood pressure ankle-brachial index (ABI). It was successfully demonstrated that the arterial stiffness can be estimated with respect to age and FTI is more strongly correlated with the pulse transit time than ABI. From the regression analysis, we also found that FTI has significant correlation PWV for a quantitative index of arterial stiffness and provides more accurate information than ABI for the characterization of arterial vessel.

Purpose: This study was performed to observe the correlation between Hot flush and pulse wave velocity(PWV), ankle brachial index(ABI) in the Climacteric women. Methods: We studied 63 climacteric women visiting OO hospital from 8th January 2007 to 22nd April 2009. The subjects were categorized in two groups, the hot flush group(37) and normal group(26). For the study, the subjects were selected by excluding the patients who receive treatment affect hot flush or have disease affect arterial states. We assessed PWV and ABI of two groups by Oscillometric method using VS-1000(Form PWV/ABI; Fukuda Denshi, Co., Ltd., Japan). From these results, we studied the correlation between hot flush and PWV/ABI by Wilcoxon Mann Whitney Test. Results: 1. It is shown that hot flush group was no significant correlation with normal group. There is no significant factor among R-PWV, L-PWV, R-ABI, L-ABI. However, L-ABI have shown relatively higher correlation with comparison to the other factors.(p-value<0.05) 2. R-PWV, L-PWV significantly increased in menopause group than in premenopause group though there is no relation to the hot flush. (p-value<0.01) Conclusion: Though the results showed no correlations between Hot flush and PWV/ABI in the Climacteric women, L-ABI showed relatively higher correlation with hot flush than others. R-PWV, L-PWV showed significant correlation between premenopause and menopause.

목 적 : 성인에서 PWV와 ABI는 동맥 경직을 측정할 수 있는 비침습적 방법으로 성인에서 고혈압, 말기 신장병, 동맥경화증의 정도를 평가할 수 있는 유용하고 간단한 방법으로 알려져 있다. 그러나 소아를 비롯한 청소년에서의 연구는 많지 않은 실정이다. 동맥경화증을 포함한 혈관의 변화가 무증상의 상태로 어린 나이에 시작해서 진행되기 때문에 청소년 고혈압, 비만 환자에서 동맥 경직의 평가가 절실하게 필요하다. 본 연구에서는 고혈압 청소년을 정상 청소년과 비교함으로 청소년에서 PWV의 유용성을 평가하고자 하였다. 방 법 : 15-16세의 청소년 413명을 고혈압군(1군 : 23명), 고혈압과 비만이 같이 있는군(2군 : 17명), 정상 대조군(3군 : 328명) 3개의 군으로 나누었다. 신장, 체중, 체질량지수를 측정하였고, Colin사의 VP-1000을 이용하여 사지의 수축기, 이완기, 평균 혈압과 양측 PWV, ABI, ET, PEP를 측정하여 비교분석 하였다. 결 과 : 우측 상완과 발목 사이의 PWV(RbaPWV)는 1군($1,186.4{\pm}134.9cm/sec$)과 2군($1,214.4{\pm}45.8cm/sec$) 모두에서 3군($939.1{\pm}84.3cm/sec$)에 비해 유의하게 높았으며(P<0.05), 2군에서 1군에 비해 유의하게 높았다(P<0.05). 좌측 상완과 발목사이의 PWV(LbaPWV) 또한 1군($1,198.4{\pm}99.8cm/sec$)과 2군($1,219.7{\pm}43.2cm/sec$) 모두에서 3군($942.1{\pm}75.8cm/sec$)에 비해 유의하게 높았으며(P<0.05), 2군에서 1군에 비해 유의하게 높았다(P<0.05). PEP/ET는 각 군 사이에 유의한 차이가 없었다. 사지의 수축기, 이완기, 평균 혈압과 PWV는 유의한 양의 상관 관계가 있었다. 사지의 수축기, 이완기, 평균 혈압은 모두 체중, 체질량지수와 유의한 양의 상관 관계가 있었으며 ABI는 체중, 체질량지수 어느 것과도 유의한 상관 관계가 없었다. 결 론 : 본태성 고혈압 청소년에서 정상 청소년에 비해 PWV가 높게 측정되었으므로 예후를 평가하기 위해서 추적 관찰이 필요하다.

Objectives: This study aimed to investigate arterial stiffness index, physical activity, and food and nutrient intake in middle-aged adults over 40 years when the incidence of cardiovascular disease begins to increase. Methods: This study included 106 subjects (48 males and 58 females) aged between 40 and 64 years. The arterial stiffness index (brachial-ankle pulse wave velocity [baPWV], and ankle-brachial index [ABI]) were measured using a blood pressure pulse wave testing device. Physical activity was assessed using the Korean version of the Global Physical Activity Questionnaire, and food and nutrient intake was calculated using the Food Frequency Questionnaire. Results: The mean age of the subjects was 54.4 years. Although the ABI of the subjects was within the normal range, they were divided into tertiles to compare physical activity and food and nutrient intake. In males, the time spent on moderate to vigorous physical activity (MVPA) was significantly higher in T3 (600.6 min/week) than in T1 (304.4 min/week). In females, the time spent in sedentary behavior was significantly lower in T3 (294.5 min/week) than in T1 (472.1 min/week). In addition, the frequency of fish consumption was significantly higher in T3 (1.27 frequency/day) than in T1 (0.64 frequency/day) in females. Polyunsaturated fatty acid (PUFA) and ω-3 fatty acid intake, adjusted for energy intake, were significantly positively correlated with ABI (r = 0.200 and r = 0.218, respectively). Conclusions: High MVPA (in males), low sedentary behavior (in females), and PUFA and ω-3 fatty acid intake through fish consumption may be associated with low peripheral artery stiffness. Therefore, arteriosclerosis can be prevented through physical activity and proper dietary therapy.

In this study, photoplethysmography(PPG) was suggested as a way to replace the ankle-brachial index(ABI) in diagnosing PAD. The method using the PPG was presented for the simplification of the PAD diagnosis method which was used before. And the index related to the health condition of the artery from the PPG measured in both big toes of the subjects through the experiment was drawn. The indexes showing the significant relativeness in the Pearson correlation analysis with the ABI were the stiffness index(SI), reflection index(RI); it was confirmed each of them had the correlation coefficient of 0.688, and 0.637 at p < 0.05. The explanation ability of the linear regression equation derived using ABI, SI and RI was 52.5%. The explanation ability of the secondary curve regression equation derived using ABI, squared SI was 54.7%. It is expected to provide patients with significant results and draw the index associated with PAD by measuring PPG easily in the real life instead of the ambulatory care field.

본 연구에서는 심혈관 질환의 위험 인자인 고혈압, 이상지질혈증 및 당뇨병이 없는 건강한 성인 남·녀를 대상으로 3축 가속도계를 이용하여 일주일간의 평소 신체활동량을 평가하고 동맥경화지표와의 연관성을 알아보고자 하였다. 가속도계를 이용한 신체활동 측정 결과, WHO 신체활동지침 준수율은 29.9%, 좌식 행동에 소비한 시간은 531.1 min/day, 저강도 활동에 소비한 시간은 281.4 min/day, 중·고강도 활동에 소비한 시간은 36.2 min/day 이였다. 활동 수준이 다른 두 군의 신체활동을 비교한 결과, CPM, 중·고강도 활동에 소비한 시간, 중·고강도 활동을 10분 이상 지속한 횟수 및 시간은 활동군이 비활동군에 비해 유의하게 높았다. 좌식 행동에 소비한 시간은 활동군이 비활동군에 비해 유의하게 낮은 반면 좌식 행동 패턴 및 baPWV와 ABI는 두 군 간에 유의한 차이가 없었다. 그러나 여자에서는 좌식 행동을 60분 이상 지속하는 횟수와 baPWV 간에 양의 상관관계가 나타났으며 좌식 행동을 50분 이상 지속하는 횟수와 ABI 간에 음의 상관관계를 보였고, 저강도 활동에 소비한 시간과 ABI 간에는 양의 상관관계를 보였다. 이는 좌식 행동을 50분 이상 지속하는 횟수가 많을수록 동맥경화 및 말초 동맥질환의 위험이 높고 저강도 활동에 소비한 시간이 많을수록 말초동맥질환의 위험이 낮음을 보여주었다. 향후 동맥경화 예방을 위한 지침 마련을 위해 다양한 연령대의 건강한 성인을 대상으로 신체활동과 함께 식품 및 영양섭취 현황, 식사 패턴, 음주 행태 등 동맥경화와 관련된 요인들이 포함된 연구의 필요성을 제안하는 바이다.
