Pulse Wave Velocity (PWV) is widely used to assess arterial elasticity and is an independent risk factor for cardiovascular disease, but it is influenced by multiple factors. Objective is to assess the impact of blood pressure and heart rate on PWV. Twenty healthy young individuals were enlisted as subjects. Real-time blood pressure monitoring was performed by non-invasive continuous blood pressure measuring instrument during the detection of subjects' carotid PWV. During real-time blood pressure monitoring, exercise load caused fluctuations in blood pressure and heart rate, and PWV changes of each subject under different blood pressure and heart rate conditions were recorded simultaneously. Among the 20 subjects, PWV was associated with blood pressure in four subjects and heart rate in one subject. PWV increased with rising blood pressure when the systolic pressure fluctuation range was >=30mmHg, diastolic pressure fluctuation range was >=18mmHg, and mean arterial pressure fluctuation range was >=20mmHg. PWV increased with rising heart rate, when the heart rate fluctuation range was >30 beats/min. Blood pressure and heart rate have some influence on PWV. However, the fluctuation range of blood pressure and heart rate should reach a certain value, the impact is significant. Keywords: Pulse wave velocity, Blood pressure, Heart rate.

Childhood and adolescent obesity has become an important public health issue, as it leads to higher risk of cardio−metabolic, orthopedic, and psychological comorbidities. The aim of this study was to evaluate the changes in nutritional state and cardiovascular system parameters in obese children. Sixty respondents aged 9−17 years with alimentary obesity participated in this research. Anthropometric parameters (body weight (BWT), body mass index (BMI), percentage of body fat (%), waist and hip circumference (WC and HC), waist−hip ratio (WHR)) and cardiovascular parameters (systolic and diastolic blood pressure (SP and DP), cardio-ankle vascular index (CAVI), ankle-brachial index (ABI), pulse wave velocity and its variability (PWV and PWVV), and parameters of pulse wave analysis) were measured. Every respondent went through two sets of measurements, the first (I.) after their admission to the children’s hospital and the second (II.) at the end of their one-month-long therapeutic stay. Statistically significant differences between measurements I. and II. were observed in the following parameters: BWT (p < 0.01), BMI (p < 0.01), WC (p < 0.01), HC (p < 0.01), DP (p < 0.01), PWV (p < 0.05), and ABI (p < 0.01). The results of this study show that obesity has a mostly negative impact on the cardiovascular health of affected children, with likely negative results in their adulthood.

Arterial compliance is an important cardiovascular parameter characterizing mechanical and structural properties of arteries and significantly influencing ventricular-arterial coupling. Decreased arterial compliance is associated with several physiological states and pathological processes. Furthermore, arterial compliance is influenced by other cardiovascular parameters even at short time scales. Today, there are numerous noninvasive methods of estimation arterial compliance in vivo introducing some level of confusion about selection of the best method for particular application and measurement setting. In this review, the most common noninvasive methods of arterial compliance estimation are summarized, discussed and categorized. Finally, interpretation of estimated arterial compliance in the context of other possible confounders is discussed.
