“…These factors decrease the elastic fibers in arteries that maintain vascular compliance, whereas the collagen fibers increase. This leads to changes in the structure and function of the arterial wall, resulting in increased vascular stiffness and decreased compliance [ 25 , 26 ]. AVI, a novel index of arterial stiffness, was found in this study not only to reflect the stiffness of the central artery, but also to correlate significantly with total peripheral vascular impedance and left ventricular contractility [ 15 ].…”

Background: To explore the value of a novel ventricular-vascular coupling index (VVI) system in relation to age, gender and body mass index (BMI). Methods: A total of 239 volunteers with single-center and cross-sectional health screening were enrolled in the study. Subjects were divided according to age (young [18–44 years], middle-age [45–59 years], old [60–80 years]), gender (male, female), and BMI (overweight/obese [BMI 24], control [BMI 24]). The left ventricle end-diastolic volume (LVEDV) and left ventricle end-systolic volume (LVESV) provided the left ventricular structure index, while the TDI provided the functional index. Also derived from routine echocardiography were the effective arterial elastance (Ea), left ventricular end-systolic elastance (Ees), and VVI. The novel VVI systems were arterial velocity pulse index (AVI), left ventricular global longitudinal strain (LVGLS), and the AVI to LVGLS ratio (AVI/LVGLS). Results: (1) Middle-age and elderly subjects had higher Ea and lower LVGLS compared to young subjects. AVI and AVI/LVGLS increased progressively from young to middle-age to old subjects. (2) Females had higher Ea, Ees and LVGLS than male subjects. No significant differences in AVI and AVI/LVGLS were observed between males and females. (3) No significant differences in Ea, Ees, VVI, AVI, LVGLS and AVI/LVGLS were observed between the overweight/obese and control groups. (4) AVI/LVGLS was negatively correlated with LVEDV and LVESV and with TDI . LVEDV, LVESV and TDI were independent predictors of AVI/LVGLS. (5) The diagnostic performance of AVI/LVGLS was higher than that of VVI in the young and middle-age groups. The diagnostic efficacy of AVI/LVGLS was higher than that of VVI in the young and old groups, and the diagnostic efficacy of AVI was higher than that of Ea. The difference in diagnostic efficacy between LVGLS and Ees was not statistically significant. The differences in diagnostic efficacy between AVI/LVGLS and VVI, AVI and Ea, and LVGLS and Ees were not statistically significant in the middle-age and old groups. Conclusions: The novel index system of ventricular-vascular coupling described here (AVI, LVGLS, and AVI/LVGLS) was more effective than traditional indexes in detecting differences in cardiovascular function between different ages groups. Clinical Trial Registration: The study protocol was registered on the official website of China Clinical Trial Registration Center (ChiCTR2000035937).

“…In addition, our study enrolled some individuals aged

30 years, and these individual CVD risk scores were calculated according to the FCVRS equation. Finally, we had no data on the body fat distribution or visceral fat adiposity of the female participants, which is a significant determinant of arterial stiffness, and we did not used other methods to detect vascular stiffness, such as ultrasound, which is a significant determinant of arterial stiffness [ 38 , 39 ]. These techniques will be assessed in future studies.…”

Background: This study investigated the correlation in parameters of arterial stiffness and cardiovascular disease (CVD) risk on age and body mass index (BMI) in Chinese females. Methods: This cross-sectional study enrolled 2220 females. Arterial stiffness was assessed by the measurement of arterial velocity pulse index (AVI) and arterial pressure volume index (API). Individual 10-year cardiovascular risk was calculated for each patient using the Framingham cardiovascular risk score (FCVRS). Results: API and AVI had a significant J-shaped relationship with age. Beginning at the age of 30 years, the API started to increase, while after 49 years, the increase in API was even steeper. AVI increased from the age of 32 years, and increased more rapidly after 56 years. The linear association between API and BMI following adjustment for age was significant (β = 0.324, 95% CI 0.247-0.400, p < 0.001). In the total study cohort, FCVRS scores increased by 0.16 scores for every 1 kg/m 2 increase in BMI and by 0.11 scores for each 1 value increase in API in the age adjusted model. Conclusions: API and BMI correlate with 10-year cardiovascular risk at various ages in females. Regardless of age, overweight females have a higher risk of increased API. Therefore API can be used for the early detection of CVD so that preventive therapy can be instituted in these high risk patients. Clinical Trial Registration: Registered on the official website of the China Clinical Trial Registration Center (20/08/2020, ChiCTR2000035937).

“…Li et al [52] used SWD to study carotid viscoelasticity in different age groups. The measurement results show that SWD of the elderly group is lower than that of the young group, while CIMT and PWV are higher than that of the young group, which proves that SWD imaging has the potential to evaluate arterial viscoelasticity.…”

Atherosclerosis (AS) is the main pathophysiological process behind CVD. Cardiovascular diseases caused by AS (such as stroke, coronary heart disease, etc.) are characterized by a high prevalence, high disability rate and high mortality, which greatly increase the burden on families and society. Thus, it is important to find AS as early as possible. When atherosclerosis occurs, the earliest sign of its structural and functional changes is arterial stiffness, and endothelial dysfunction is the key link.Arteriosclerosis is caused by the imbalance between collagen and elastin in the arteries. Elastin fibers gradually decrease, and stiffer collagen fibers increase, making the vessels less elastic. Endothelial dysfunction also affects the regulatory function of arterial vascular tension, and accelerates the remodeling of the vascular wall, to make blood vessels more rigid. Quantitative measurement of arterial stiffness and carotid intima-media thickness (CIMT) is an important tool for early detection of vascular lesions. At present, ultrasound technology including echo tracking (ET), wave intensity (WI), real-time shear wave elastography (SWE), ultrafast pulse wave velocity (ufPWV), shear wave dispersion (SWD), cardio-ankle vascular index (CAVI), arterial velocity pulse index and arterial pressure volume index (AVI and API) has the advantages of being noninvasive, realtime, economical and reproducible in the assessment of atherosclerosis, and is widely used in the early diagnosis of AS. Most importantly, the change in arterial hardness detected by traditional ultrasound technology precedes the change in intima-media thickness, suggesting that ultrasonic elasticity monitoring may be a more sensitive method of predicting AS and can find and prevent cardiovascular diseases earlier.
