  • 심혈관계 위험인자를 비침습적으로 분석할 수 있는 PWV에 관한 다수의 선행연구에서 의견이 분분하고, 결과에 대한 일관성이 부족한 부분을 재현하고자 연구에 임하였으며, 더욱이 날로 증가하고 있는 노인을 대상으로 운동참여 여부와 성별에 따른 노인의 말초동맥파속도(baPWV), 신체구성과 심혈관계 변인의 상관성 및 재변인의 차이를 검증하는데 연구의 목적이 있다. 규칙적인 운동을 수행해온 노인남성 39명(이하, 운동군M) 과 운동을 수행해 오고 있지 않은 동일 연령대의 노인남성 38명(이하, 통제군M), 규칙적인 운동을 수행해온 노인여성 40명(이하, 운동군F) 과 운동을 수행해오고 있지 않은 동일 연령대의 노인여성 37명(이하, 통제군F)을 대상으로 변인에 대한 상관성과 집단별 재변인들 간의 차이를 알아본 결과 노인남성 운동군의 baPWV range와 근육량(r=0.357, p=0.026), 수축기혈압(r=0.468, p=0.003), rbaPWV (r=0.406, p=0.010), lbaPWV (r=0.333, p=0.038)가 통계적으로 유의한 상관관계를 보였고, 노인남성 통제군의 경우는 baPWV range와 심박수(r=0.395, p=0.014), rbaPWV (r=0.598, p=0.000), lbaPWV (r=0.602, p=0.000)가 유의한 상관성을 보였다. 노인여성 운동군은 baPWV range와 진단명(r=0.321, p=0.044), 수축기혈압 (r=0.399, p=0.011), 이완기혈압(r=0.545, p=0.000), rbaPWV (r=0.648, p=0.000), lbaPWV (r=0.676, p=0.000)가 유의한 상관성을 보였고, 노인여성 통제군 경우는 baPWV range와 나이 (r=0.471, p=0.003), rbaPWV (r=0.836, p=0.000), lbaPWV (r=0.801, p=0.000)가 통계적으로 유의한 상관성을 보였다. 반면 말초동맥파속도 변인 중 통계적으로 유의한 차이를 보인 그룹은 없는 것으로 나타났고, 요둔위($F_{3,150}=9.197$, p=0.000), 근육량($F_{3,150}=74.295$, p=0.000), 체지방율($F_{3,150}=35.045$, p=0.000), 수축기 혈압($F_{3,150}=3.525$, p=0.017)이 통계적으로 유의한 차이를 나타냈다. 본 연구에서는 집단별 특성에 따라 다양한 결과가 나타난다는 사실을 알 수 가 있었으며, 신체구성 변인과 심혈관계 변인 중 수축기 혈압은 운동 여부에 따라 민감한 변화와 차이를 보인 것으로 보아 노인의 경우 운동그룹은 신체구성과 심혈관계 일부 변인에 변화를 줄 수 있다고 단정지어 볼 수 있겠으나, 위팔-발목 맥박파전파속도에 대해서는 일관된 결과가 도출되지 않아서 이에 대한 지속적인 연구가 필요한 것으로 사료된다.

  • Cardiovascular disease (CVD) risk factors may be acting several decades before CVD becomes manifest. Data from young subjects may be valuable in further elucidating at this issue. We evaluated the association between baPWV (brachial-ankle pulse wave velocity) and cardiovascular risk factors in apparently healthy young adults. A total of 46 male and 91 female adolescents aged $18{\sim}25 years$ were studied. baPWV increased in a dose-responsive manner as the number of metabolic syndrome components. In both gender groups, baPWV was positively correlated with age. In males, waist, circumference total cholesterol, and LDL-cholesterol were positively correlated with baPWV, and in females, blood pressure (BP) was positively correlated with baPWV. Age, gender, mean BP, and Homeostasis model assessment insulin resistance (HOMA-IR) were found to be independent factors associated with baPWV levels. In conclusion, mean BP, age, gender, and HOMA-IR were associated with baPWV in young adults. This result suggests that multiple cardiovascular risk factors may be associated with an increased risk of arterial stiffness in young adults.

  • Background: Osteoprotegerin (OPG) plays protective roles against the development of vascular calcification (VC) which greatly contributes to the increased cardiovascular events in patients with chronic kidney disease (CKD). The present study aimed to find the non-traditional, kidney-related cardiovascular risk factors correlated to serum OPG and the effect of serum OPG on the arterial stiffness measured by brachial ankle pulse wave velocity (baPWV) in patients with the pre-dialysis CKD. Methods: We cross-sectionally analyzed the data from the patients in whom baPWV and the serum OPG were measured at the time of enrollment in a prospective pre-dialysis CKD cohort study in Korea. Results: Along with traditional cardiovascular risk factors such as age, diabetes mellitus, pulse pressure, and baPWV, non-traditional, kidney-related factors such as albuminuria, plasma level of hemoglobin, total $CO_2$ content, alkaline phosphatase, and corrected calcium were independent variables for serum OPG in multivariate linear regression. Reciprocally, the serum OPG was positively associated with baPWV in multivariate linear regression. The baPWV in the 3rd and 4th quartile groups of serum OPG were higher than that in the 1st quartile group after adjustments by age, sex and other significant factors for baPWV in linear mixed model. Conclusion: Non-traditional, kidney-related cardiovascular risk factors in addition to traditional cardiovascular risk factors were related to serum level of OPG in CKD. Serum OPG level was significantly related to baPWV. Our study suggests that kidney-related factors involved in CKD-specific pathways for VC play a role in the increased secretion of OPG into circulation in patients with CKD.

  • Pulse wave velocity (PWV) is used to non-invasively estimate the severity of arteriosclerosis by measuring arterial stiffness. Increased arterial stiffness measured by PWV stands for progressive arteriosclerosis and is caused by atherosclerotic risk factors. This study is focused on how brachial-ankle pulse wave velocity (baPWV) is related to the leading risk factors for arteriosclerosis or atherosclerosis. Subjects were 114, 69 males and 45 females who are in 60's and had baPWV test for acute stroke. The results are as follows: the group with increased arterial stiffness showed significant increase in HbA1c, total cholesterol, BSBP (brachial artery systolic blood pressure), BDBP (brachial artery diastolic blood pressure), CSBP (central artery systolic blood pressure), CDBP (central artery diastolic blood pressure), augmentation index (AIx) and diabetes mellitus. Correlation analysis between baPWV and atherosclerotic risk factor showed significant relationship in age, HbA1c, LDL cholesterol, BSBP, BDBP, CSBP, CDBP and augmentation index. baPWV was independently related to age and BSBP in multiple linear regression analysis. The group with increased arterial stiffness was independently related to BDBP in multiple logistic regression analysis. This study might be meaningful in evaluating the relationship between arterial stiffness and atherosclerotic risk factor in a new way, and be helped to make various studies for cardiovascular disease.

  • Objectives: We evaluated the association between common carotid artery intima-media thickness (CCA-IMT), brachialankle pulse wave velocity (baPWV), carotid plaque, and peripheral arterial disease (PAD) as indicators of macroangiopathy and diabetic retinopathy as an indicator of microangiopathy in type 2 diabetic patients. Methods: We analyzed 605 type 2 diabetic patients registered at a public health center in Korea. Following overnight fasting, venous blood and urine samples were collected and analyzed. The CCA-IMT, levels of carotid plaque, baPWV, and ankle-brachial index (ABI) of the subjects were assessed. We used non-mydriatic fundus photography to diagnose diabetic retinopathy. Multiple logistic regression analyses were used to evaluate the association between macroangiopathy and diabetic retinopathy. CCA-IMT and baPWV were divided into tertiles: CCA-IMT, 0.39 to 0.65 mm, 0.66 to 0.78 mm, and 0.79 to 1.30 mm; baPWV, 9.9 to 15.8 m/s, 15.9 to 18.9 m/s, and 19.0 to 38.0 m/s. Results: The association between baPWV and diabetic retinopathy remained significant after adjustment, with an increasing odds ratio (OR) in the second tertile (OR, 2.41; 95% confidence interval [CI], 1.27 to 4.55) and the third tertile (OR, 4.63; 95% CI, 2.33 to 9.21). No significant differences were observed in carotid plaque, PAD, and each tertile of CCA-IMT. Conclusions: BaPWV was associated with diabetic retinopathy, while CCA-IMT, carotid plaque, and PAD were not. This study suggests that the association between macroangiopathy and microangiopathy may be attributable to functional processes rather than structural processes within the vascular system.

  • 50세 이상 건강한 성인을 대상으로 baPWV로 측정한 동맥경직도 수준과 염증인자와 동맥경직도와의 관련성을 파악하기 위하여 본 연구를 수행하였다. 2007년과 2008년에 수행된 광주광역시 동구연구(Dong-gu Study)의 기반조사에 참여한 50세 이상 주민 4617명을 대상으로 하였으며, 다중회귀분석을 시행하여 전통적인 심뇌혈관질환 위험요인을 통제한 상태에서 baPWV와 CRP, GGT와 WBC 등의 염증반응인자와의 관련성을 알아보았다. 평균 baPWV는 남자 $17.0{\pm}4.0\;m/s$, 여자 $16.2{\pm}3.6\;m/s$로 남, 여 간에 통계적으로 유의한 차이가 있었고, 연령이 증가할수록 baPWV는 통계적으로 유의하게 증가하는 경향을 보였다. 성, 연령, 흡연상태, 체질량지수, 수축기혈압, 공복혈당, 고혈압 또는 당뇨병의 투약 여부, 혈청 지질, 요산과 ALT 등의 전통적인 심뇌혈관질환 위험요인을 통제한 상태에서 WBC (${\beta}$=0.158, p<0.0001), hs-CRP(${\beta}$=0.244, p=0.026)와 GGT (${\beta}$=0.003, p<0.0001)는 baPWV와 통계적으로 유의하게 독립적인 관련성이 있음을 알 수 있었다. 결론적으로 baPWV로 측정한 동맥경직도 지표는 염증반응인자와 관련이 있음을 알 수 있었다. baPWV 등의 동맥경직도 측정 지표는 동맥 기능의 초기변화를 반영하고 일반적으로 알려져 있는 심혈관질환 위험요인과 유의한 상관관계를 가지고 있어, 이를 이용하여 심혈관질환의 위험을 예측하는데 활용할 수 있을 것으로 생각된다.

  • Purpose: Pulse wave velocity (PWV) is an indicator of arterial stiffness, and is considered a marker of vascular damage. However, a genome-wide association study analyzing single nucleotide polymorphisms (SNPs) associated with brachial-ankle PWV (baPWV) has not been conducted in healthy populations. We performed this study to identify SNPs associated with baPWV in healthy populations in Korea. Materials and Methods: Genomic SNPs data for 2,407 individuals from three sites were analyzed as part of the Korean Genomic Epidemiologic Study. Without replication samples, we performed multivariable analysis as a post hoc analysis to verify the findings in site adjusted analysis. Healthy subjects aged between 40 and 70 years without self-reported history or diagnosis of hypertension, diabetes, hyperlipidemia, heart disease, cerebrovascular disease and cancer were included. We excluded subjects with a creatinine level >1.4 mg/dL (men) and 1.2 mg/dL (women). Results: In the site-adjusted association analysis, significant associations (P<$5{\times}10^{-8}$) with baPWV were detected for only 5 SNPs with low minor allele frequency. In multivariable analysis adjusted by age, sex, height, body mass index, mean arterial pressure, site, smoking, alcohol, and exercise, 11 SNPs were found to be associated (P<$5{\times}10^{-8}$) with baPWV. The 5 SNPs (P<$5{\times}10^{-8}$) linked to three genes (OPCML, PRR35 and RAB40C) were common between site-adjusted analysis and multivariable analysis. However, meta-analysis of the result from three sites for the 11 SNPs showed no significant associations. Conclusion: Using the recent standard for genome-wide association study, we did not find any evidence of significant association signals with baPWV.

  • Background: Pulsatility of cerebral arteries and aortic stiffness have been associated with white matter hyperintensities (WMH). We explored which is better correlated with the severity of WMH in a population with acute lacunar infarct. Methods: We included patients with acute small subcortical infarcts who underwent transcranial Doppler (TCD) and brachial ankle pulse wave velocity (baPWV). Exclusion criteria were any stenosis or occlusion on major cerebral arteries on magnetic resonance angiography; poor temporal insonation windows; ankle brachial index < 0.9; and atrial fibrillation. We assessed the performance of the pulsatility index of bilateral middle cerebral arteries (PI-MCA) and baPWV for predicting moderate-to-severe WMH, defined as an Age Related White Matter Changes score > 5, and then sought to find independent predictors using binary logistic regression analysis. Results: Eighty-three patients (56 males, mean age $61.5{\pm}11.4$) participated in the study. Uni-variate analysis showed old age and high PI-MCA were significantly correlated with moderate-to-severe WMH. However, baPWV was not associated with the severity of WMH. Multivariate analysis revealed old age (odds ratio per 1-year increase, 1.068; p = 0.044) and upper tertile of PI-MCA (odds ratio, 5.138; p = 0.049) were independently associated with moderate-to-severe WMH. Receiver-operating characteristics showed PI-MCA differentiated those with and without moderate-to-severe WMH with an area under the curve of 0.719. Conclusions: PI-MCA derived from TCD was better correlated with the severity of WMH than baPWV in a population with lacunar infarction. Pulsatility of cerebral arteries may better predict cerebral small vessel disease than the aortic stiffness index.

  • Background: BMI alone may not serve as an index of obesity because it does not reflect body composition. The present study aimed to compare arterial stiffness as assessed by the brachial-ankle pulse wave velocity (ba-PWV) among groups defined by body fat percentage (pBF) and BMI. Methods: This cross-sectional study was based on 1,700 participants (1,044 men and 656 women) who completed a health screening examination at a national hospital between January 2011 and February 2016. Participants were divided into four groups according to BMI and pBF: normal fat and normal weight (NFNW); excessive fat and normal weight (EFNW); normal fat and obese (NFO); and excessive fat and obese (EFO). The ba-PWV and other cardiometabolic factors were compared among the four groups in men and women separately. Results: For both sexes, the NFNW group had a lower metabolic risk compared to that in the other groups (EFNW, NFO, and EFO). After adjusting for multiple variables, the NFO males had a significantly lower ba-PWV compared to those in the other groups, including NFNW males. The NFO group had significantly more skeletal muscle mass and muscle mass compared the other groups (P<0.05). Among women, the NFNW group had a significantly lower ba-PWV compared the other groups, even after adjusting for multiple variables. Conclusion: Lower pBF in obese men may be associated with improved cardiovascular risk.
