Hypertension-specific association of cardio-ankle vascular index with subclinical left ventricular function in a Chinese population: Danyang study. J Clin Hypertens (Greenwich) 2024; 26:553-562. [PMID: 38563687 PMCID: PMC11088429 DOI: 10.1111/jch.14803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 02/07/2024] [Accepted: 03/07/2024] [Indexed: 04/04/2024]
Abstract
The association of cardio-ankle vascular index (CAVI), with subclinical cardiac dysfunction in hypertensive patients is unclear. We aim to examine their relationship in hypertensive patients compared with that in normotensive subjects. Our study included 1887 subjects enrolled from Danyang between 2018 and 2019. CAVI was measured using VaSera VS-1500A device. We performed conventional echocardiography to measure ejection fraction (EF) and E/A, tissue Doppler to measure mitral annular early diastolic velocities (e'), and speckle-tracking to estimate left ventricular (LV) global longitudinal strain (GLS). LV mass index (76.3, 80.0, and 84.0 g/m2), and E/e' (7.6, 8.2, and 8.8) were increased and GLS (21.1, 21.0, and 20.4%), E/A (1.2, 1.0, and 0.8) and e' velocity (11.2, 9.4, and 8.2 cm/s) was decreased from tertiles 1-3 of CAVI on unadjusted analyses (P < .001). After adjustment for covariates, GLS, E/A, and e' were still significantly decreased from tertiles 1-3 of CAVI (P ≤ .04). Further sensitive analyses revealed a similar association pattern for diastolic function but not systolic function. Compared with the lowest tertile, subjects with a top tertile of CAVI were at higher risk of subclinical LV systolic dysfunction in hypertensive patients (OR = 2.61; P = .005). Increased CAVI is associated with worse subclinical diastolic function. However, this relationship of CAVI to subclinical systolic function was more prominent in hypertensive patients.

Influence of Obstructive Apnea Index on Persistent Left Ventricular Dysfunction in Patients with ST-Segment Elevation Myocardial Infarction. J Clin Med 2024; 13:986. [PMID: 38398299 PMCID: PMC10888575 DOI: 10.3390/jcm13040986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 02/03/2024] [Accepted: 02/07/2024] [Indexed: 02/25/2024] Open
Abstract
Background: We retrospectively investigated the effects of the severity and classification of sleep-disordered breathing (SDB) on left ventricular (LV) function in patients with ST-segment elevation myocardial infarction (STEMI). Methods: A total of 115 patients with STEMIs underwent a sleep study using a multichannel frontopolar electroencephalography recording device (Sleep Profiler) one week after STEMI onset. We evaluated LV global longitudinal strain (LV-GLS) using two-dimensional echocardiography at one week and seven months. Patients were classified as no SDB (AHI < 5 events/h), obstructive SDB (over 50% of apnea events are obstructive), and central SDB (over 50% of apnea events are central). Due to the device's limitations in distinguishing obstructive from central hypopnea, SDB classification was based on apnea index percentages. Results: The obstructive apnea index (OAI) was significantly associated with LV-GLS at one week (r = 0.24, p = 0.027) and seven months (r = 0.21, p = 0.020). No such correlations were found for the central apnea index and SDB classification. Multivariable regression analysis showed that the OAI was independently associated with LV-GLS at one week (β = 0.24, p = 0.002) and seven months (β = 0.20, p = 0.008). Conclusions: OAI is associated with persistent LV dysfunction assessed by LV-GLS in STEMI.

Impact of sleep-disordered breathing on overnight changes in arterial stiffness in patients with acute heart failure. Hypertens Res 2024; 47:342-351. [PMID: 37783770 DOI: 10.1038/s41440-023-01448-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 08/25/2023] [Accepted: 08/31/2023] [Indexed: 10/04/2023]
Abstract
Overnight increases in arterial stiffness associated with sleep-disordered breathing may adversely affect patients with acute heart failure. Thus, we investigated overnight changes in arterial stiffness and their association with sleep-disordered breathing in patients hospitalized for acute heart failure. Consecutive patients with acute heart failure were enrolled. All participants underwent overnight full polysomnography following the initial improvement of acute signs and symptoms of acute heart failure. The arterial stiffness parameter, cardio-ankle vascular index (CAVI), was assessed before and after polysomnography. Overall, 60 patients (86.7% men) were analyzed. CAVI significantly increased overnight (from 8.4 ± 1.6 at night to 9.1 ± 1.7 in the morning, P < 0.001) in addition to systolic and diastolic blood pressure (from 114.1 mmHg to 121.6 mmHg, P < 0.001; and from 70.1 mmHg to 78.2 mmHg, P < 0.001, respectively). Overnight increase in CAVI (ΔCAVI ≥ 0) was observed in 42 patients (70%). The ΔCAVI ≥ 0 group was likely to have moderate-to-severe sleep-disordered breathing (i.e., apnea-hypopnea index ≥15, 55.6% vs 80.9%, P = 0.047) and greater obstructive respiratory events (29.4% vs 58.5%, P = 0.041). In multivariable analysis, moderate-to-severe sleep-disordered breathing and greater obstructive respiratory events were independently correlated with an overnight increase in CAVI (P = 0.033 and P = 0.042, respectively). In patients hospitalized for acute heart failure, arterial stiffness, as assessed by CAVI, significantly increased overnight. Moderate-to-severe sleep-disordered breathing and obstructive respiratory events may play an important role in the overnight increase in cardio-ankle vascular index.

Abstract
In 2014, Japan was estimated to have approximately 27 million patients with hypertension (HT), and the ultimate goal of treatment is to prevent complications of HT, including heart failure (HF). The major structural changes in the heart that cause HF are left ventricular (LV) hypertrophy (LVH) and the resulting LV diastolic dysfunction. However, in patients with HT with well-controlled blood pressure (BP), whether they are in HF stage A (only HT) or B (with organic heart disease) is often unclear. It has been reported that strict BP control suppresses LVH, and the improvement of LVH leads to the suppression of cardiovascular complications. Thus, detecting HF stage B HT and providing appropriate treatment lead to the suppression of HF onset. This review focuses on the detection and treatment of organic heart disease in HT.

Abstract
Objective To determine whether retinal vessel geometry is associated with systemic arterial stiffness, as determined by the cardio-ankle vascular index (CAVI). Methods This single-center retrospective cross-sectional study included 407 eyes of 407 subjects who underwent routine health exams, including CAVI and fundus photography. Retinal vessel geometry was measured using a computer-assisted program (Singapore "I" Vessel Assessment). Subjects were classified into two groups based on CAVI values: high CAVI (≥9) or low CAVI (<9). The main outcome measures included the association of retinal vessel geometry and CAVI value evaluated using multivariable logistic regression models. Results Three hundred forty-three subjects (343, 84.3%) were in the low CAVI group, and 64 (15.7%) subjects were in the high CAVI group. Multivariable logistic linear regression analyses adjusted for age, sex, body mass index, smoking status, mean arterial pressure, and the presence of hypertension, diabetes mellitus, and dyslipidemia showed a significant association between high CAVI values and the following retinal vessel geometry parameters: central retinal arteriolar equivalent caliber (CRAE; adjusted odds ratio [AOR], 0.95; 95% confidence interval [CI], 0.89-1.00; P = 0.043), fractal dimension of arteriolar network (FDa; AOR, 4.21 × 10-4; 95% CI, 2.32 × 10-7-0.77; P = 0.042), and arteriolar branching angle (BAa; AOR, 0.96; 95% CI, 0.93-0.99; P = 0.007). Conclusions Increased systemic arterial stiffness had a significant association with retinal vessel geometry related to arterial narrowing (CRAE), less branching complexity of the arterial tree (FDa), and acute arteriolar bifurcation (BAa).

Abstract
BACKGROUND Arterial stiffness indices are used to assess the material properties of the arterial wall and are associated with cardiovascular events. Aortic stenosis (AS) is commonly caused by degenerative calcification and can be associated with increased arterial stiffness. However, the clinical implications of arterial stiffness indices in AS patients before and after treatment are unknown. METHODS This single-center observational study enrolled 150 consecutive patients who underwent transcatheter aortic valve implantation (TAVI) for severe AS. The cardio-ankle vascular index (CAVI) was measured before and after TAVI. The patients were divided into two groups according to the CAVI values before and after TAVI: high CAVI group and low CAVI group. Patient and echocardiographic data and clinical outcomes, including cardiac death and hospitalization for heart failure (HF), were compared. RESULTS The pre- and postprocedural CAVI was 7.90 (6.75-9.30) and 9.65 (8.90-10.65), respectively. In the analyses with preprocedural CAVI, preprocedural echocardiographic aortic valve peak flow velocity was significantly lower in the high CAVI group. No significant differences between the two groups were observed in the occurrence of cardiac death or hospitalization for HF. In the analyses with postprocedural CAVI, B-type natriuretic peptide levels and E/e' ratio after TAVI were significantly higher in the high CAVI group. The composite of cardiac death and hospitalization occurrence for HF was significantly higher in the high CAVI group. CONCLUSION CAVI before TAVI is mainly affected by the AS severity, while CAVI after TAVI is associated with left ventricular diastolic dysfunction and late cardiac events, which may reflect arterial stiffness.

Are Non-Invasive Modalities for the Assessment of Atherosclerosis Useful for Heart Failure Predictions? Int J Mol Sci 2023; 24:ijms24031925.

Abstract
Heart failure (HF) is becoming an increasingly common issue worldwide and is associated with significant morbidity and mortality, making its prevention an important clinical goal. The criteria evaluated using non-invasive modalities such as coronary artery calcification, the ankle-brachial index, and carotid intima-media thickness have been proven to be effective in determining the relative risk of atherosclerotic cardiovascular disease. Notably, risk assessments using these modalities have been proven to be superior to the traditional risk predictors of cardiovascular disease. However, the ability to assess HF risk has not yet been well-established. In this review, we describe the clinical significance of such non-invasive modalities of atherosclerosis assessments and examine their ability to assess HF risk. The predictive value could be influenced by the left ventricular ejection fraction. Specifically, when the ejection fraction is reduced, its predictive value increases because this condition is potentially a result of coronary artery disease. In contrast, using these measures to predict HF with a preserved ejection fraction may be difficult because it is a heterogeneous condition. To overcome this issue, further research, especially on HF with a preserved ejection fraction, is required.

Influence of the cardio-ankle vascular index on chronic-phase left ventricular dysfunction after ST-segment elevation myocardial infarction. J Hypertens 2022; 40:1478-1486.

Abstract
OBJECTIVE This study aimed to investigate the possible influence of arterial stiffness assessed by the cardio-ankle vascular index (CAVI) on chronic-phase left ventricular dysfunction in patients with ST-segment elevation myocardial infarction (STEMI). METHODS A total of 208 consecutive patients with first STEMI (age, 64 ± 11 years; 86% men) who underwent reperfusion therapy within 12 h of onset were enrolled. We analysed arterial stiffness by measuring CAVI in a stable phase after admission and performed two-dimensional echocardiography at baseline and 7 months' follow-up. Subsequently, we assessed left ventricular global longitudinal strain (LV-GLS) to evaluate left ventricular function. A total of 158 (75.9%) patients underwent baseline cardiac magnetic resonance (CMR). We estimated left ventricular infarct size by measuring peak levels of creatine kinase-myocardial band (CK-MB), and CMR-late gadolinium enhancement (LGE). RESULTS On the basis of the median CAVI value, the patients were allocated into high CAVI (CAVI ≥ 8.575) and low CAVI (CAVI < 8.575) groups. The groups showed no statistically significant differences in LV-GLS at baseline (-13.5% ± 3.1 vs. -13.9% ± 2.7%, P = 0.324). However, LV-GLS was significantly worse in the high CAVI group than in the low-CAVI group at 7 months (-14.0% ± 2.9 vs. -15.6% ± 3.0%, P < 0.001). Stratified by CAVI and peak CK-MB or LGE, the four groups showed significant differences in LV-GLS at 7 months after STEMI (both P < 0.001). Multivariate linear regression analysis with the forced inclusion model showed that CAVI was an independent predictor of LV-GLS at 7 months ( P = 0.015). CONCLUSION CAVI early after STEMI onset was significantly associated with chronic-phase LV-GLS. In addition, combining CAVI with CK-MB or LGE improves its predictive ability for evaluation of chronic-phase LV-GLS. Thus, the arterial stiffness assessment by CAVI was an important factor related to chronic-phase left ventricular dysfunction after the first STEMI.

Abstract
Arterial stiffness increases with age, as well as in various pathological states, including obesity, diabetes mellitus, smoking, and dyslipidemia, and it has important consequences for cardiovascular health. Arterial stiffness plays a central role in hemodynamic dysfunction characterized by excess pulsatility; specifically, it leads to heart failure, cerebrovascular disease, and renal failure. Among measures of arterial stiffness, carotid-femoral pulse wave velocity is considered as the reference standard; however, it has not been incorporated into routine clinical practice. Cardio-ankle vascular index (CAVI), which is a marker of arterial stiffness measured from the origin of the aorta to the ankle, was developed in 2004. CAVI is based on stiffness parameter β, which is theoretically independent of blood pressure at the time of measurement. CAVI applies stiffness parameter β to arterial segments between the heart and ankle. The measurement of CAVI is simple and well-standardized, and its reproducibility and accuracy are acceptable. Several studies have demonstrated that CAVI is high in patients with various atherosclerotic risk factors, and treatment of cardiovascular risk factors and lifestyle modifications improve CAVI. Several prospective studies have investigated the association between CAVI and future cardiovascular events in the general population and in patients with cardiovascular risk factors. A cut-off value of 9.0 is proposed for predicting patients at a high risk of cardiovascular events. From this review, it is clear that CAVI may be useful in the prevention of cardiovascular disease.

Abstract
Assesment of arterial stiffness the substantional prognostic factor for evaluating complications of cardiovascular diseases (CVD) in patients with atherosclerosis, hypertension and type 2 diabetes, may be performed using different parameters, including cardio-ankle vascular index (CAVI). The main purpose of this review is to analyze data from studies where CAVI is used to test the arterial wall stiffness in magistral vessels. CAVI measurement is non-invasive and performed by portable devices which makes it comfortable for ambulatory use in patients who come for a check-up and also in those who already are hospitalized. It does not require any special knowledge from investigator and the test lasts a couple of minutes long. CAVI does not depend on blood pressure changes and is more specific in structural changes of arterial wall assessment than brachial-ankle pulse wave velocity (baPWV). CAVI shows considerable correlation with markers of CVD like atherosclerotic plaques in vessels, diastolic disfunction of left ventricle and angina pectoris. CAVI may be used for early monitoring and assessing the lesions of target organs in patients with atherosclerosis, chronic hypertension and type 2 diabetes. Establishing CAVI as a standart parameter in assessing patients who are at risk of CVD can help to improve complications prevention, reduce mortality and prolong their lifespan.

Abstract
AIM The purpose of this study is to investigate the impact of arterial stiffness assessed using Cardio-ankle Vascular Index (CAVI) on long-term outcome after acute coronary syndrome (ACS). METHODS A total of 387 consecutive patients (324 males; age, 64±11 years) with ACS were enrolled. We examined CAVI and brachial-ankle pulse wave velocity (ba PWV) as the parameters of arterial stiffness. The patients were divided into two groups according to the cut-off value of CAVI determined using the receiver operating characteristic curve for the prediction of major adverse cardiovascular events (MACE): low-CAVI group, 177 patients with CAVI <8.35; high-CAVI group, 210 patients with CAVI ≥ 8.35. The primary endpoint was the incidence of MACE (cardiovascular death, recurrence of ACS, heart failure requiring hospitalization, or stroke). RESULTS A total of 62 patients had MACE. Kaplan-Meier analysis demonstrated a significantly higher probability of MACE in the high-CAVI group than in the low-CAVI group (median follow-up: 62 months; log-rank, p<0.001). Multivariate analysis suggested that CAVI was an independent predictor of MACE (hazard ratio [HR], 1.496; p=0.02) and cardiovascular death (HR, 2.204; p=0.025), but ba PWV was not. We investigated the incremental predictive value of adding CAVI to the GRACE score (GRS), a validated scoring system for risk assessment in ACS. Stratified by CAVI and GRS, a significantly higher rate of MACE was seen in patients with both higher CAVI and higher GRS than the other groups (p<0.001). Furthermore, the addition of CAVI to GRS enhanced net reclassification improvement (NRI) and integrated discrimination improvement (IDI) (NRI, 0.337, p=0.034; and IDI, 0.028, p=0.004). CONCLUSION CAVI was an independent long-term predictor of MACE, especially cardiovascular death, adding incremental clinical significance for risk stratification in patients with ACS.

Abstract
Arterial stiffness is recognized mainly as an indicator of arteriosclerosis and a predictor of cardiovascular events. Cardio-ankle vascular index (CAVI), which reflects arterial stiffness from the origin of the aorta to the ankle, was developed in 2004. An important feature of this index is the independency from blood pressure at the time of measurement. A large volume of clinical evidence obtained using CAVI has been reported. CAVI is high in patients with various atherosclerotic diseases including coronary artery disease and chronic kidney disease. Most coronary risk factors increase CAVI and their improvement reduces CAVI. Many prospective studies have investigated the association between CAVI and future cardiovascular disease (CVD), and proposed CAVI of 9 as the optimal cut-off value for predicting CVD. Research also shows that CAVI reflects afterload and left ventricular diastolic dysfunction in patients with heart failure. Furthermore, relatively acute changes in CAVI are observed under various pathophysiological conditions including mental stress, septic shock and congestive heart failure, and in pharmacological studies. CAVI seems to reflect not only structural stiffness but also functional stiffness involved in acute vascular functions. In 2016, Spronck and colleagues proposed a variant index CAVI0, and claimed that CAVI0 was truly independent of blood pressure while CAVI was not. This argument was settled, and the independence of CAVI from blood pressure was reaffirmed. In this review, we summarize the recently accumulated evidence of CAVI, focusing on the proposed cut-off values for CVD events, and suggest the development of new horizons of vascular function index using CAVI.

Abstract
Background Chronic systemic inflammation is an important causative factor in the pathogenesis of atherosclerosis. However, the effect of chronic Helicobacter pylori (Hp) infection on arterial stiffness, a predictor of cardiovascular events, remains unclear. We evaluated the association between Hp infection and arterial stiffness in asymptomatic healthy individuals. Methods Arterial stiffness was evaluated using the cardio-ankle vascular index (CAVI). We included subjects who underwent CAVI and anti-Hp IgG antibody evaluations, simultaneously, between March 2013 and July 2017. Demographic characteristics and metabolic and cardiovascular parameters were compared with respect to anti-Hp IgG antibody status. Multivariable logistic regression analyses were performed to determine the effect of Hp-seropositivity and conventional cardiovascular risk factors on arterial stiffness. Results Of 2,251 subjects, 1,326 (58.9%) were included in the Hp-seropositive group. Median age (P < 0.001) and systolic blood pressure (P = 0.027) were significantly higher in the Hp-seropositive than in the Hp-seronegative group. Levels of LDL-cholesterol were significantly higher in the Hp-seropositive than in the Hp-seronegative group (P = 0.016). Other serum metabolic parameters were not significantly different between the two groups. The median CAVI value and the proportion of subjects with a CAVI ≥ 8 were significantly higher in the Hp-seropositive than in the Hp-seronegative group (both P < 0.001). On multivariable logistic regression analyses, Hp-seropositivity, age, body mass index, waist circumference, smoking, hypertension, diabetes mellitus, and dyslipidemia were significantly associated with high CAVI values. In the subgroup analysis conducted according to age group, a tendency towards an increased association between Hp-seropositivity and CAVI was observed with increasing age, even though the difference did not reach the statistical significance. Conclusions Hp-seropositivity was significantly associated with arterial stiffness. Hp infection may contribute to the development of cardiovascular diseases.

Abstract
Arterial stiffness is an age-related disorder. In the medial layer of arteries, mechanical fracture due to fatigue failure for the pulsatile wall strain causes medial degeneration vascular remodeling. The alteration of extracellular matrix composition and arterial geometry result in structural arterial stiffness. Calcium deposition and other factors such as advanced glycation end product-mediated collagen cross-linking aggravate the structural arterial stiffness. On the other hand, endothelial dysfunction is a cause of arterial stiffness. The biological molecular mechanisms relating to aging are known to involve the progression of arterial stiffness. Arterial stiffness further applies stress on large arteries and also microcirculation. Therefore, it is closely related to adverse outcomes in cardiovascular and cerebrovascular system. Cardio-ankle vascular index (CAVI) is a promising diagnostic tool for evaluating arterial stiffness. The principle is based on stiffness parameter β, which is an index intended to assess the distensibility of carotid artery. Stiffness parameter β is a two-dimensional technique obtained from changes of arterial diameter by pulse in one section. CAVI applied the stiffness parameter β to all of the arterial segments between heart and ankle using pulse wave velocity. CAVI has been commercially available for a decade and the clinical data of its effectiveness has accumulated. The characteristics of CAVI differ from other physiological tests of arterial stiffness due to the independency from blood pressure at the time of examination. This review describes the pathophysiology of arterial stiffness and CAVI. Molecular mechanisms will also be covered.

Abstract
Background The cardio-ankle vascular index (CAVI) is a novel physiological marker of atherosclerosis that reflects systemic arterial stiffness. The aim of this study was to clarify the clinical significance of CAVI as a risk factor for cardiovascular diseases (CVDs) in elderly patients with type 2 diabetes mellitus. Methods This cross-sectional study enrolled 216 elderly (≥ 65 years) outpatients with type 2 diabetes mellitus who were undergoing antidiabetic treatment (96 males and 120 females; mean age, 75 ± 7 years (mean ± standard deviation)). Associations between CAVI and various clinical parameters were examined. Results CAVI was significantly higher in patients with a history of CVD than in those without a history of CVD (10.4 ± 1.4 vs. 9.5 ± 1.0, respectively, P < 0.001). There were significantly positive correlations between CAVI and various clinical parameters, such as skin autofluorescence (r = 0.47, P < 0.001), high-sensitivity cardiac troponin T levels (r = 0.39, P < 0.001), and reactive oxygen metabolite levels (r = 0.28, P < 0.001). Furthermore, multiple regression analyses revealed that these clinical parameters ((skin autofluorescence (β = 0.30, P < 0.001), high-sensitivity cardiac troponin T levels (β = 0.18, P < 0.001), reactive oxygen metabolite levels (β = 0.15, P < 0.01), and a history of CVD (β = 0.19, P < 0.001)) were independent variables when CAVI was used as a subordinate factor. Conclusion Findings of this study indicate that CAVI may be an important CVD risk factor in elderly patients with type 2 diabetes mellitus. Further investigations in a large number of prospective studies, including intervention therapies, are required to validate our results.

Abstract
The cardio-ankle vascular index (CAVI) is a measure of global arterial stiffness. We hypothesized that CAVI is associated with left ventricular (LV) function and geometry in individuals without structural heart disease. We measured CAVI in 600 participants (mean age 60.3±14.6 years, 54% men) without history of atherosclerotic cardiovascular disease who were referred for transthoracic echocardiography. Linear regression analysis was used to assess the association of CAVI with LV function (peak mitral annular systolic s' and early diastolic velocity e') and structure (LV mass index (LVMI) and relative wall thickness (RWT)). Older age, male sex, lower body mass index, history of hypertension, diabetes and chronic kidney disease were each associated with a higher CAVI (adjusted R2 = 0.56, all p < 0.01). A higher CAVI was associated with lower s' and e', and greater RWT, independent of age, sex, systolic BP and other conventional cardiovascular risk factors (all p < 0.05); a borderline association of higher CAVI with greater LVMI ( p = 0.05) was present. Associations with e', s' and RWT were similar in women and men but the association with LVMI was stronger in women than in men ( p for interaction = 0.02, multivariable-adjusted β = 6.92, p < 0.001 in women; p > 0.1 in men). In conclusion, a higher CAVI, a measure of global arterial stiffness, is associated with worse LV systolic function, worse diastolic relaxation, and greater LV RWT in both men and women, and with LVMI in women.

Abstract
Objective Vascular abnormality includes two forms, arteriosclerosis (ARS) and atherosclerosis (ATS), which coexist in patients with cardiovascular (CV) diseases. However, whether their combination may lead to a worsening status in those patients remains unclear. We therefore aimed to investigate the association of ARS and/or ATS with hypertensive target organ damage (TOD). Methods From June 2014 to August 2015, a total of 1,599 community-dwelling elderly subjects (aged >65 years) from northern Shanghai were recruited. Vascular measurements, such as carotid–femoral pulse wave velocity (cf-PWV), ankle–brachial index (ABI) and carotid plaque, were conducted on each participant, and ARS was defined as cf-PWV >12 m/s, while ATS was defined as participants who have carotid plaque or ABI <0.9. Within the framework of comprehensive CV examinations, CV risk factors were assessed, and asymptomatic TOD was evaluated by measuring participants’ left ventricular mass index (LVMI), peak transmitral pulsed Doppler velocity/early diastolic tissue Doppler velocity (E/Ea), urinary albumin–creatinine rate (UACR) and estimated glomerular filtration rate (eGFR). Results Although LVMI, E/Ea and eGFR were significantly different among subjects with or without ARS and/or ATS (P<0.02), in full adjustment model, only E/Ea showed the independent and significant difference (P=0.023). Moreover, E/Ea was significantly different between participants with ARS or ATS and those without ARS or ATS (P=0.045), while there was no significant difference between participants with ARS and ATS and those without ARS or ATS (P=0.28). Similar results were obtained in the multivariate logistic regression of left ventricular diastolic dysfunction (LVDD). With similar adjustment, LVDD was significantly associated with ATS (P=0.01) but not with ARS (P=0.99). Conclusion In the community-dwelling elderly Chinese, among hypertensive TOD, LVDD was significantly associated with ATS but not with ARS. The proportion of patients with LVDD was not significantly different despite the presence of both ATS and ARS, when compared to patients with ATS alone.

Abstract
BACKGROUND The cardio-ankle vascular index (CAVI) is a new noninvasive index to evaluate arterial stiffness. We investigated whether CAVI can predict severity, extent, and burden of coronary artery disease by comparing results with cardiac computed tomographic angiography (CCTA). HYPOTHESIS CAVI may predict the presence of subclinical atherosclerosis. METHODS We prospectively enrolled 95 patients (66% male; mean age, 50 ± 16 years) who underwent both CCTA and CAVI consecutively. We evaluated if CAVI correlated with (1) severe stenosis (≥50%); (2) plaque extent, determined by a segment-involvement score (SIS), defined by the total number of coronary artery segments containing any plaque; and (3) plaque burden, determined by a segment-stenosis score (SSS), defined by the extent of obstruction of coronary luminal diameter in individual coronary artery segments. RESULTS Bivariate analysis showed a statistically significant relationship not only between CAVI and SIS, but also between CAVI and SSS (r2 = 0.4, P < 0.0001 for SIS; r2 = 0.36, P < 0.0001 for SSS). Multivariable logistic analysis demonstrated that CAVI is significantly associated with SSS >5 (odds ratio [OR]: 2.3, 95% confidence interval [CI]: 1.1-7.8, P = 0.03) and SIS >5 (OR: 2.3, 95% CI: 1.1-5.8, P = 0.02), but not severe stenosis (OR: 1.7, 95% CI: 0.9-4.3, P = 0.13), after adjusting for age, sex, chest pain, hypertension, dyslipidemia, family history, diabetes, and current smoking. CONCLUSIONS We demonstrated that CAVI had a significant relationship with subclinical coronary atherosclerosis evaluated by CCTA, especially in relation to plaque burden and plaque extent, but not severe stenosis. Thus, CAVI may reflect coronary atherosclerosis burden more than severity.

Abstract
Left ventricular (LV) diastolic dysfunction is considered the main cause of heart failure with preserved ejection fraction (HFpEF). There have been few reports on the correlation between LV diastolic dysfunction and arterial stiffness in patients with clinical cardiovascular disease.This cross-sectional study enrolled 100 patients (67 men, 33 women; mean age, 70 years). All participants were diagnosed with cardiovascular disease. A total of 89 (89%) patients had coronary artery disease or HF. Patients with reduced EF and valvular disease were excluded. Arterial stiffness was assessed by the cardio-ankle vascular index (CAVI), and LV diastolic dysfunction was estimated using echocardiography. The patients were divided into two groups based on the median value of CAVI. In all patients the ratio of early diastolic transmitral flow velocity to early diastolic mitral annular velocity (E/e') was significantly higher in the high CAVI group than in the low CAVI group (15.5 ± 6.4 versus 12.5 ± 2.9, P = 0.003). In the HF subgroup, E/e' was also significantly higher in the high CAVI group than in the low CAVI group (17.2 ± 5.9 versus 13.0 ± 3.1, P = 0.026). In univariate regression analysis, CAVI was significantly associated with E/e' in all patients (β = 0.28, P = 0.004) and in HF patients (β = 0.4, P = 0.028). Also in multivariate analysis, CAVI remained as an independent predictive factor of E/e' (β = 0.252, P = 0.037).A high CAVI was independently associated with LV diastolic dysfunction in patients with clinical cardiovascular disease. These results suggested that arterial stiffness contributed to the development of LV diastolic dysfunction.

Abstract
Shark liver oil (SLO) has long been used as a traditional health food, with a particular benefit for vascular health, in Japan. The aim of this study was to assess the effect of dietary supplementation with SLO on arterial stiffness and peripheral microvascular function in otherwise healthy middle-aged and older males with slightly increased arterial stiffness. A randomized, double-blind, placebo-controlled, parallel study design was used to assign 41 healthy males with a mean age of 59.0±4.0 years (range, 45-69 years) to either SLO (n=21) or placebo (n=20) treatment for eight weeks. The effects on arterial stiffness and peripheral microvascular function were assessed by the cardio-ankle vascular index (CAVI) and by measurement of hand blood flow to cutaneous tissues using a laser Doppler perfusion imaging (LDPI) technique, respectively. Although the magnitude of the changes in the CAVI value during the eight-week intervention for the SLO group did not significantly differ from that for the placebo group, the changes in the CAVI value for the former group were significantly associated (r=0.575, P<0.01) with age. It was also found that the LDPI values at week 8 were significantly lowered (P<0.05) compared with the baseline values in the placebo group, while no change was observed in the SLO group, resulting in a significant difference in the changes between the two groups (P=0.002). Neither SLO supplementation-related adverse side-effects nor any abnormal changes in routine laboratory tests, including lipid profiles and anthropometric and haemodynamic parameters, were observed throughout the intervention. SLO may have the potential to safely improve vascular health in middle-aged and elderly males.

Abstract
PURPOSE The blood concentration of cardiac troponin T (ie, high-sensitivity cardiac troponin T [hs-cTnT]), measured using a highly sensitive assay, represents a useful biomarker for evaluating the pathogenesis of heart failure or predicting cardiovascular events. However, little is known about the clinical significance of hs-cTnT in metabolic syndrome. The aim of this study was to examine the factors affecting hs-cTnT elevation in Japanese metabolic syndrome patients. PATIENTS AND METHODS We enrolled 258 metabolic syndrome patients who were middle-aged males without a history of cardiovascular events. We examined relationships between hs-cTnT and various clinical parameters, including diagnostic parameters of metabolic syndrome. RESULTS There were no significant correlations between hs-cTnT and diagnostic parameters of metabolic syndrome. However, hs-cTnT was significantly correlated with age (P<0.01), blood concentrations of brain natriuretic peptide (P<0.01), reactive oxygen metabolites (markers of oxidative stress, P<0.001), and the cardio-ankle vascular index (marker of arterial function, P<0.01). Furthermore, multiple regression analysis revealed that these factors were independent variables for hs-cTnT as a subordinate factor. CONCLUSION The findings of this study indicate that in vivo oxidative stress and abnormality of arterial function are closely associated with an increase in hs-cTnT concentrations in Japanese metabolic syndrome patients.

Abstract
Arterial stiffness has been known to be a surrogate marker of arteriosclerosis, and also of vascular function. Pulse wave velocity (PWV) had been the most popular index and was known to be a predictor of cardiovascular events. But, it depends on blood pressure at measuring time. To overcome this problem, cardio-ankle vascular index (CAVI) is developed. CAVI is derived from stiffness parameter β by Hayashi, and the equation of Bramwell-Hill, and is independent from blood pressure at a measuring time. Then, CAVI might reflect the proper change of arterial wall by antihypertensive agents. CAVI shows high value with aging and in many arteriosclerotic diseases and is also high in persons with main coronary risk factors. Furthermore, CAVI is decreased by an administration of α1 blocker, doxazosin for 2-4 hours, Those results suggested that CAVI reflected the arterial stiffness composed of organic components and of smooth muscle cell contracture. Angiotensin II receptor blocker, olmesartan decreased CAVI much more than that of calcium channel antagonist, amlodipine, even though the rates of decreased blood pressure were almost same. CAVI might differentiate the blood pressure-lowering agents from the point of the effects on proper arterial stiffness. This paper reviewed the principle and rationale of CAVI, and the possibilities of clinical applications, especially in the studies of hypertension.

Abstract
BACKGROUND Several lines of evidence suggest that atrial fibrillation (AF) may be a consequence of vascular disease. We investigated the relationship between cardio-ankle vascular index (CAVI), a new index of arterial stiffness, and the presence of paroxysmal AF (PAF). METHODS AND RESULTS 181 outpatients (91 patients with PAF and 90 age- and gender-matched subjects without PAF) were analysed for their sinus rhythm. The CAVI was significantly higher in patients with PAF than in subjects without PAF (9.0±1.0 vs 8.7±0.8, p<0.01). In all subjects, the CAVI was significantly correlated with the left ventricular mass index (r=0.30, p<0.01), left atrial diameter (r=0.22, p<0.01), and augmentation index, a parameter of wave reflection (r=0.32, p<0.01), in addition to age, systolic blood pressure and pulse pressure. Logistic analysis demonstrated that the CAVI was independently associated with PAF even after adjustment for confounding factors. The adjusted OR of PAF was 1.8 for each unit increase in the CAVI (p=0.01). CONCLUSIONS Our finding suggests that increased arterial stiffness may be involved in the maintenance of AF.

Abstract
BACKGROUND Thyroid hormone is associated with arterial stiffness and left ventricular diastolic function in hypothyroid disease. The relationship of thyroid hormone level to cardio-ankle vascular index (CAVI) and left ventricular diastolic function, however, remains unclear in subjects with subclinical hypothyroidism. METHODS AND RESULTS We conducted a cross-sectional study of 83 patients with untreated subclinical hypothyroidism and compared them with 83 randomly selected controls from health check-ups. Log N-terminal prohormone of brain natriuretic peptide (NT-proBNP), C-reactive protein (CRP), and arterial stiffness were measured. In addition, we measured early diastolic mitral annular velocity (E') in 43 participants with subclinical hypothyroidism and in 40 controls. When compared with the control group, patients with subclinical hypothyroidism had higher logNT-proBNP (1.9±0.5 vs. 1.7±0.3pg/ml, P<0.05), CRP (0.22±0.04 vs. 0.09±0.06mg/dl, P<0.05), and CAVI (8.8±1.7 vs. 7.8±1.4, P<0.001) and lower E' (5.8±1.7 vs. 7.5±2.1cm/s, P<0.001). CAVI was significantly associated with logNT-proBNP, CRP and E' in the subclinical hypothyroidism group. CONCLUSIONS High logNT-proBNP was associated with a raised CAVI in patients with subclinical hypothyroidism. Subclinical hypothyroidism may be a risk factor for cardiovascular events related to arterial stiffening and left ventricular diastolic dysfunction.

Abstract
AIM The cardio-ankle vascular index (CAVI) reflects arterial stiffness from the aorta to the ankle, independent of blood pressure (BP). We investigated the age-stratified CAVI in healthy, normotensive individuals to evaluate the effects of age on arterial stiffness. METHODS The CAVI and peripheral BP were determined in healthy, normotensive Koreans 20 to 79 years of age. The subjects had no history of cardiovascular disease and did not take any medications for hypertension, diabetes mellitus or dyslipidemia (N = 1,380; 44.1% in men). RESULTS The mean systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP) were 117, 75 and 42 mmHg, respectively. The CAVI increased linearly with age and was determined using the following equation: CAVI = 5.0 + 0.048 × age (year) in men (r(2) = 0.395, p < 0.001), CAVI = 4.8 + 0.045 × age (year) in women (r(2) = 0.450, p < 0.001). However, SBP, DBP and PP did not change progressively with age. Age emerged as the major determinant of the CAVI in a stepwise multiple regression analysis (r(2) change = 43.1%). CONCLUSIONS The CAVI scores increased with age in the healthy, normotensive individuals, whereas SBP, DBP and PP did not. Age was the dominant risk factor for the progression of arterial stiffness. These data suggest that the CAVI is a sensitive marker of the arterial aging process, above and beyond conventional upper arm BP.

Abstract
AIM The cardio-ankle vascular index (CAVI) is an index of arterial stiffness. We investigated the association of CAVI with the severity of coronary artery calcification (CAC) and coronary stenosis by coronary computed tomography angiography (CTA) in an asymptomatic population. METHODS A total of 549 asymptomatic Korean individuals who underwent CAVI and CTA were analyzed retrospectively. CAC and coronary stenosis were measured by CTA and assessed for the correlation with CAVI. RESULTS The degree of CAC and coronary stenosis demonstrated a significant correlation with CAVI (r= 0.187, p<0.001 and r= 0.212, p<0.001 for the CAC score and stenosis, respectively). After adjustment for potential confounders, including age, gender, hypertension, diabetes mellitus, and dyslipidemia, a predefined cutoff value of CAVI ≥8 was associated with advanced CAC (CAC ≥300) and significant coronary stenosis (stenosis ≥50%). Specifically, the adjusted odds ratio (95% confidence interval) of CAC ≥300 and coronary stenosis ≥50% was 3.57 (1.92-6.66) and 2.81 (1.13-7.00), respectively. Additional inclusion of CAVI improved the predictive power of the receiver operating characteristic curves for predicting coronary atherosclerosis based on traditional risk factors; the area under the curve for predicting CAC ≥300 and coronary stenosis ≥50% increased from 0.739 to 0.791 (p for difference= 0.023), and from 0.761 to 0.842 (p= 0.032), respectively. CONCLUSIONS CAVI reflects coronary atherosclerosis and may be used as a screening tool for assessing subclinical atherosclerotic burden in an asymptomatic population.

Abstract
BACKGROUND The cardio-ankle vascular index (CAVI) was developed as an indicator of arterial wall stiffness, and it is less influenced by blood pressure (BP). We investigated the relationship between the CAVI and coronary artery disease (CAD), and evaluated the effects of rapid changes in BP induced by anesthetics on CAVI. MATERIALS AND METHODS We measured the CAVI in 76 patients before and after the administration of anesthetics for elective cardiovascular surgery. The patients were assigned to groups with or without CAD (0VD). The CAD group was then divided into 3 subgroups based on the number of stenotic vessels (1VD, 2VD, and 3VD). We compared the CAVI between CAD and 0VD, and changes in BP during the induction of anesthesia. All data were analyzed using Stat View 5.0 software. RESULTS Systolic BP significantly decreased from 145 ± 21 to 107 ± 20 mmHg, whereas CAVI was not altered after the administration of intravenous anesthetics. Changes in BP and in pre-anesthetic CAVI (pre-CAVI) did not correlate. The pre- and post-anesthetic values for the CAVI (post-CAVI) in the 0VD and CAD groups were 8.34 ± 1.01 and 8.44 ± 1.39, and 9.95 ± 1.22 and 10.12 ± 1.56, respectively. Both values were higher in the CAD, than in the 0VD group (P < 0.05). CONCLUSION The CAVI is independent of BP and reproducible regardless of the induction of anesthesia and is significantly higher in patients with CAD. The CAVI might be able to predict atherosclerosis and coronary artery stenosis in patients undergoing cardiovascular surgery.

Abstract
AIM The cardio-ankle vascular index (CAVI) reflects overall arterial stiffness from the aorta to the ankle, independent of blood pressure. Cerebral small vessel diseases (SVDs), including white matter lesions (WML), silent lacunar infarction (SLI) and cerebral microbleeds (CMB), are considered to increase the risk of stroke and cognitive impairment further. We aimed to investigate the association of cerebral SVD with CAVI in asymptomatic young and middle-aged subjects. METHODS Asymptomatic Korean individuals aged 30 to 59 years old without neurologic disease who had CAVI and brain magnetic resonance imaging (MRI) were evaluated retrospectively. RESULTS Among 484 subjects, cerebral SVDs (advanced WML, SLI and CMB) were found in 20 (4.1%). Subjects with SVDs tended to be older and to have higher systolic blood pressure (SBP) and higher CAVI. From multivariate regression analysis, including pulse pressure (PP) or SBP, CAVI showed a significant association with SVD [adjusted OR (95% CI): 1.889 (1.094-3.263), p= 0.002 and 1.793 (1.020-3.153), p= 0.043, for PP and SBP, respectively]. When CAVI was assessed by quartiles, the highest quartile of CAVI (CAVI >7.65) showed a significant association with SVD, after adjustment for PP [adjusted OR (95% CI): 2.766 (1.115-6.866), p= 0.028]. CONCLUSION In young and middle-aged subjects, cerebral SVD was significantly associated with arterial stiffness measured by CAVI after adjusting for PP or SBP.

Abstract
BACKGROUND The strength of each heart beat and the stiffness of large arteries contribute to blood pressure (BP). When the large arteries are stiff and their resistance greater, the afterload increases and this may change the function of the heart. However, the relation between common carotid artery stiffness and heart function in hypertensive patients has not been clarified. METHODS Two hundred and twenty hypertensive patients underwent transthoracic and carotid echocardiography. Measurements of local arterial stiffness were taken at the right common carotid artery level and stiffness parameter (β), pressure-strain elasticity modulus and intima-media thickness were calculated. Brachial cuff BP was measured just before starting the carotid study. The patients with any cardiovascular disease, diabetes mellitus, stroke, transient ischemic attack, or carotid stenosis were excluded. RESULTS Carotid artery stiffness parameter (β) was correlated with age and left ventricular mass index (p < 0.005). Even though β was not correlated with LV systolic function, it was inversely correlated with diastolic function as measured by early mitral annular velocity. When the artery was stiffer, early mitral annular velocity (e') decreased (p < 0.001) and the index of left atrial (LA) pressure (early diastolic mitral inflow E velocity/e') increased (p = 0.001). In logistic regression, diastolic dysfunction was affected by age (beta -0.385, p = 0.001), LA volume index (beta 0.175, p = 0.013) and β (beta -0.273, p = 0.019). CONCLUSION In hypertensive patients, changes in carotid artery stiffness can affect the diastolic function, independent of age and LA volume index. Therefore, measurements and control of carotid stiffness can play an important role in the prevention of diastolic heart failure.

Abstract
AIM The cardio-ankle vascular index (CAVI) reflects overall arterial stiffness from the aorta to the ankle, independent of blood pressure. We aimed to investigate the association of fat burden assessed by visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT) and epicardial adipose tissue (EAT) with CAVI in an asymptomatic population. METHODS A total of 260 asymptomatic Korean individuals who had CAVI, abdominal computed tomography (CT) and coronary CT were evaluated retrospectively. The VAT, SAT, EAT and SAT to VAT ratio (SVR) were measured and assessed for correlation with CAVI. RESULTS Different fat compartments showed different correlations with arterial stiffness as assessed by CAVI. The amount of fat measured by VAT (r= 0.129, p= 0.037), EAT (r=0.193, p= 0.002) and SVR (r=-0.168, p= 0.007) showed a significant correlation with CAVI, whereas the amount of total abdominal fat and SAT did not (p= 0.261 and p= 0.434 respectively). From step-wise multivariate regression analysis including age, pulse pressure, fasting blood sugar level, VAT, SVR and EAT, EAT (p= 0.036) and age (p<0.001) showed significant associations with CAVI. When quartiles of CAVI were assessed, EAT showed serial increment, whereas SVR showed a stepwise decrease from the first quartile to fourth quartile of CAVI (p=0.041). CONCLUSION VAT, EAT and SVR, which reflect metabolic risk, have shown significant correlations with arterial stiffness measured by CAVI. EAT showed an independent association with arterial stiffness after adjusting for covariables by multivariable correlation analysis. Among the different parameters reflecting fat burden, EAT showed the strongest correlation with CAVI.

Abstract
AIM A novel arterial stiffness index, the cardio-ankle vascular index (CAVI), has been proposed. To clarify the properties of CAVI, the effects of beraprost sodium (BPS), a prostaglandin (PG) I2 analogue, which has a potent vasodilating effect, on CAVI were studied and comparing with brachialankle pulse wave velocity (baPWV) in healthy volunteers. METHODS Male volunteers (n=18, 46.3±4.2 yr) were enrolled in this study and administered BPS (40 µg). CAVI and baPWV were measured every hour for 4 hours. RESULTS When BPS was administered to 18 healthy volunteers, systolic blood pressure and diastolic blood pressure fluctuated slightly, but the means did not change. CAVI significantly decreased in the 1st hour from 8.3±0.34 (mean±SE) to 7.9±0.34 (p<0.05) and this decrease persisted for 3 hours, whereas baPWV did not significantly change. ΔbaPWV each time was significantly correlated with both Δsystolic blood pressure and Δdiastolic blood pressure, but ΔCAVI did not correlate with either Δsystolic blood pressure (r=-0.12, p=0.38) or Δdiastolc blood pressure (r=-0.22, p=0.10). CONCLUSIONS Beraprost sodium did not decrease blood pressure, but decreased CAVI, whereas baPWV did not change. These results indicate that CAVI partly reflected the contraction of arterial smooth muscle cells.

Abstract
AIMS Plasma brain natriuteric peptide (BNP) is an established marker of cardiovascular events in individuals without heart failure. Although the cardio-ankle vascular index (CAVI) is clinically used as a parameter of arterial stiffness, its usefulness for predicting cardiovascular events has not been fully examined. This study aimed to evaluate the association among CAVIs, plasma BNP levels and left ventricular (LV) hypertrophy and dysfunction in hypertensive patients. METHODS We enrolled 136 hypertensive patients (69±10 years) who had been taking antihypertensive medications for at least one year. Echocardiography was performed to evaluate LV hypertrophy and function. Plasma BNP levels and CAVIs were also measured simultaneously. RESULTS CAVI was correlated with plasma BNP (r =0.245, p =0.004). Multiple linear regression analysis revealed three independent determinants of CAVI: age (β =0.568, p <0.001), diameter of ascending aorta (β =0.289, p <0.001), and diabetes (β =0.207, p =0.003). In addition, multiple linear regression analysis revealed two independent determinants of the plasma BNP level: left atrial diameter (β =0.334, p <0.001) and CAVI (β =0.256, p =0.002). CONCLUSION The present study indicates that increased CAVI is independently associated with elevated plasma BNP produced by increased LV afterload, that is, arterial stiffness, in hypertensive patients. Moreover, the present study raises the possibility that CAVI may be as useful as the plasma BNP level for predicting the risk of cardiovascular events in hypertensive patients.

Abstract
It was previously reported that the brachial-ankle pulse wave velocity (baPWV) is elevated in preeclamptic women. However, baPWV is strongly affected by blood pressure. Recently, a new index of vascular stiffness, the cardioankle vascular index (CAVI), was developed. CAVI is thought to be an index independent of blood pressure. We assessed CAVI in normotensive and hypertensive pregnant women. We studied a total of 109 Japanese women consisting of 23 nonpregnant healthy women (group A), 45 normotensive pregnant women (group B), 28 pregnant women complicated with established preeclampsia (group C), and 13 pregnant women with chronic hypertension (group D). The subject remained supine while the blood pressure, baPWV, and CAVI were recorded. No significant difference in baPWV was present between groups C and D, but the difference in CAVI was significantly high in group D. We believe that we can distinguish the vessel structural change between chronic hypertension and preeclampsia through simultaneous baPWV and CAVI measurements.

Abstract
Adipocyte fatty acid binding protein (A-FABP) has been reported to be involved in insulin resistance, lipid metabolism, and atherosclerosis; however, little is known about the effect of medication on the change in circulating A-FABP in human subjects. We evaluated the effects of angiotensin II type 1 receptor blocker (ARB) on arterial stiffness and its association with serum A-FABP in patients with hypertension. Thirty patients newly diagnosed with essential hypertension were treated with olmesartan (20 mg/day), an ARB, for 6 months. Serum levels of A-FABP and high-sensitivity C-reactive protein (hsCRP) were examined and the cardio-ankle vascular index (CAVI), which is a marker of arterial stiffness, was also determined. Serum A-FABP at baseline was significantly correlated with the body mass index (r = 0.45, P = 0.01), homeostasis model assessment as a marker of insulin resistance (r = 0.53, P < 0.01), and systolic blood pressure (r = 0.37, P = 0.047), and tended to be correlated with low-density lipoprotein cholesterol, triglyceride, and CAVI. Olmesartan treatment resulted in a significant decrease in CAVI, serum A-FABP levels, and hsCRP, besides a significant reduction of blood pressure. Multiple regression analysis revealed that the change in CAVI was independently correlated with the change in serum A-FABP. Olmesartan ameliorated arterial stiffness in patients with hypertension, which may be involved in the reduction of serum A-FABP.

Abstract
We aimed to evaluate whether there was a difference in the arterial stiffness assessed by the cardio-ankle vascular index (CAVI) between patients with acute coronary syndrome (ACS) and those with stable angina pectoris (SAP). A total of 199 consecutive patients, 79 with ACS and 120 with SAP, who underwent emergency or elective coronary revascularization were enrolled. The CAVI was measured within 2 days after the procedures, and was compared between the ACS and SAP patients. As parameters related to arteriosclerosis, carotid intima-media thickness (IMT) and number of stenotic coronary vessels were also evaluated. Although IMT was significantly greater in SAP patients (2.1±1.1 vs. 2.4±0.9; P=0.022), CAVI was significantly higher in ACS patients (10.0±1.7 vs. 9.3±1.3; P=0.0012). After an adjustment for the clinical parameters with a significant difference between the two patient groups, CAVI remained significantly higher in ACS patients than in SAP patients (odds ratio 1.92, 95% confidence interval 1.30-3.02; P=0.0023). A multiple linear regression analysis revealed that age (β=0.44; P<0.0001) and ACS (β=0.3; P<0.0001) were the independent determinants of CAVI. A significant decrease in CAVI was observed at 6 months of follow-up as compared with the acute phase in 18 patients with ACS (10.9±1.6 vs. 10.0±1.5; P=0.019). In conclusion, CAVI was significantly and independently higher in patients with ACS than in those with SAP, which might result from a transient increase in the CAVI caused by acute myocardial ischemia.

Abstract
AIM The cardio-ankle vascular index (CAVI) has been proposed as a new noninvasive marker of arterial stiffness independent of blood pressure. We investigated the association of the CAVI with coronary atherosclerosis and left ventricular (LV) systolic and diastolic function in patients with ischemic heart disease (IHD). METHODS A total of 206 consecutive subjects undergoing coronary angiography were enrolled. CAVI measurement and echocardiography were performed simultaneously. Patients having significant coronary stenosis were classified into the IHD group. RESULTS CAVI in the IHD group (n=133) was significantly higher than in the non-IHD group(n=73)(9.1+/-1.3 vs. 8.7+/-1.2, p=0.02). In all IHD patients, CAVI was negatively correlated with LV ejection fraction (LVEF)(r=-0.31, p<0.01), LV mass index (r=0.24, p<0.01) and angiographic scores of coronary atherosclerosis. Stepwise regression analysis revealed that CAVI was independently associated with LVEF, along with a history of myocardial infarction, LV mass index, and left atrial diameter in all IHD patients (p<0.01). In the sub-analysis of IHD patients with preserved LVEF, CAVI was correlated with echocardiographic parameters regarding LV diastolic function. Multivariate analysis demonstrated that the increased CAVI was significantly associated with LV diastolic dysfunction in patients with preserved LVEF. CONCLUSION CAVI, a new parameter of aortic stiffness, was independently associated with LV systolic and diastolic function as well as coronary artery disease in IHD patients.

Abstract
AIM Chronic kidney disease (CKD) is associated with an increased risk of cardiovascular disease, although it has yet to be established whether CKD is an independent risk factor for arterial stiffness in community residents. The purpose of this study was to determine the correlation between the cardio-ankle vascular index (CAVI) and estimated glomerular filtration rate (eGFR) in the general population. METHODS We studied 881 consecutively enrolled subjects undergoing health checkups. CAVI was calculated automatically from the pulse volume record, blood pressure and the vascular length from the heart to the ankle. CKD was evaluated by the eGFR. RESULTS The distribution of eGFR was as follows: 241 with eGFR (mL/min/1.73m(2)) > or =90; 572 with eGFR 60-89; 65 with eGFR 30-59; 3 with eGFR 15-29; 0 with eGFR <15. Linear regression analysis showed that CAVI was negatively correlated significantly with eGFR, while multiple regression analysis using CAVI as an objective variable, adjusted for conventional atherosclerotic risk factors and eGFR as explanatory variables, demonstrated that CAVI was an independent determinant of eGFR. We also showed that stepwise increments of CAVI occurred with progressive deterioration of CKD. CONCLUSION CAVI was independently correlated with eGFR indicating that CKD is associated with arterial stiffness in the general population.
