Automated ultrasound edge ‐tracking software comparable to established semi‐automated reference software for carotid intima‐media thickness analysis
Summary Many commercial ultrasound systems are now including automated analysis packages for the determination of carotid intima‐media thickness (cIMT); however, details regarding their algorithms and methodology are not published. Few studies have compared their accuracy and reliability with previously established automated software, and those that have were in asymptomatic adults. Therefore, this study compared cIMT measures from a fully automated ultrasound edge‐tracking software (EchoPAC PC, Version 110.0.2; GE Medical Systems, Horten, Norway) to an established semi‐automated reference software (Artery Measuremen...

Does postexercise modelled capillary blood flow accurately reflect cardiovascular effects by different exercise intensities?
Summary Blood flow (BF) in exercising muscles is an important factor for exercise capacity. Recently, a non‐invasive method to estimate capillary BF (Qcap) was introduced. Using this method, the Fick principle is re‐arranged by using relative differences in deoxygenated haemoglobin (ΔHHb) as a surrogate for arteriovenous O2 difference and pulmonary oxygen uptake (VO2) instead of muscular oxygen uptake. The aim of this study was to examine (I) the relationship between Qcap and exercise intensity during and following exercise, and (II) to critically reflect the Qcap approach. Seventeen male subjects completed six bouts ...

Aspects of carotid structure and function in health and different stages of chronic kidney disease
ConclusionIn mild‐to‐moderate CKD, there were no significant differences in carotid artery structure or function compared with healthy subjects. Only patients with advanced CKD and older ages showed signs of arterial remodelling. Our study indicates that vascular alterations occur in advanced CKD, with SBP and age as important contributing factors. (Source: Clinical Physiology and Functional Imaging)
