While reported methods require arterial pressure and diameter measurements from a single site to assess intrabeat changes in C, we present an image-free fast ultrasound device that performs this by capturing diameter waveforms from two proximal locations on an artery.. Methods: The functionality was assessed on eight normotensive participants (26 ± 4 years). By perturbing blood pressure through a short duration moderate lower body negative pressure intervention [2], CD and CF pulse wave velocities corresponding to diastolic and 80% of peak pressure were measured from the carotid artery. Human NIBP system (ADInstruments, India) was used for monitoring continuous pressure.","PeriodicalId":8466,"journal":{"name":"Artery Research","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42777069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the relationship between arterial stiffness and BP is complex. In addition, changes in BP may contribute to increased risk of cardiovascular disease associated with abnormal lipid profiles. So far, results from published studies have been inconclusive. Objectives: To evaluate lipid profiles and BP, and their association with CAVI values in elderly participants. Methods: The study included 95 elderly Thai individuals. Anthropometric data, lipid profiles, and BP and CAVI values were established. Participants were then divided into low-CAVI (CAVI < 9, n = 50) and high-CAVI groups (CAVI ≥ 9, n = 45). Stepwise linear and logistic regression models were used. Results: The high-CAVI group had significantly higher BP and hypertension levels, than the low-CAVI group. The mean age of the high-CAVI group was also higher (≥65 years). CAVI value was positively correlated with Systolic Blood Pressure (SBP) and Pulse Pressure (PP) in the high-CAVI group. Stepwise multiple regression analysis showed SBP ( b = 0.43, p < 0.01) and hip circumference ( b = −0.23, p = 0.01) were associated with CAVI values.
