Sažetak
Background and aim: Circumferential arterial strain (CAS) is inversely related to beta stiffness index. However, arterial strain can be calculated using inner luminal diameter or outer luminal diameter of a blood vessel. The aim of this investigation was to explore the possible difference between the luminal beta stiffness index (beta L) versus midwall beta stiffness index (beta W). Patients and methods: The investigation was conducted on 108 healthy volunteers. The subjects underwent cardiovascular and risk factor assessment. Measurements were performed on Aloka 5500-SSD Prosound ultrasound platform using B mode and M mode analysis on common carotid arteries (CCA) ; beta indexes were computed. Paired t-test was used for evaluation. Results: There were 76 women (71%) and 31 men (29%) aged 49, 79+/-14, 09 yrs, median 52 yrs. There were 97 (81%) normotensives and 20 (19%) well managed hypertensives with average blood pressure values of 122+/-11 over 77+/-7 mmHg. Average body-mass index was 25, 56+/-3, 70 kg/m2 ; there were 34 overweight subjects (32%). Half of the subjects were smokers (58, 45%). Beta L in the right CCA was 4, 76+/-1, 34 and in the left CCA 4, 86+/-1, 89). Beta W in the right CCA was 6, 09+/-1, 89 and in the left CCA 5, 71+/-2, 03). Statistical significance was found between beta L and beta W in both CCA investigated separately (p<0, 05). There was no side-to-side difference for beta L nor beta W. Conclusion: This investigation confirms that active vascular wall participation is necessary in circulatory regulation.
