“…In this case a blood pulse waveform is clearly observed. A zoom of one of the obtained pulses is shown in Figure 17 which compares very well with the typical arterial pulse waveform of a healthy person, showing details that have diagnostic relevance about the circulatory system condition [Stoner et al, 2012]. It is worth noting the clean waveform obtained in Figure 17, considering the tick distance of the vertical axis (50 µm) which evidences the micrometric motion detection capability of this technology.…”

The paper presents the experimental evaluation of 94 GHz CW-FM Radar that can be configured as a Ground Based SAR (Synthetic Aperture Radar) for high resolution imaging and deformation control. This system has been designed to obtain and analyze data of deformations on different types of bodies, being able to detect range changes of the order of micrometers. After indoor testing and validation measurements, several experimental results obtained in different scenarios are presented. Finally the possibility of using the system for remote contact-less patient monitoring is analyzed.

“…Large number of the general population can be screened for detecting and also the severity of CAD. Instruments like PPG are easily available, and high level of technical expertise is not required as needed in Ultrasound and Magnetic resonance imaging (MRI) [11,19,20]. As our second objective was correlation between RI and SI, which is found to be significant.…”

Introduction: Arterial compliance will result in stabilizing the fluctuations in arterial pressure and blood flow. So arterial stiffness can be a good indicator for monitoring the cardiovascular system. Arterial stiffness can be measured using indices like reflection index (RI), stiffness index (SI) and Brachial Finger Pulse Wave Velocity (BFPWV).Objectives: Aim of our study was to evaluate the changes in RI, SI and BFPWV during different phases of the menstrual cycle and to correlate RI with SI in healthy female subjects between the age group of 18-30 years from Bangalore, India. Materials and Methods:Basal recordings of RI and SI were determined by Photo Pulse Plethysmography (PPG) picked up from the fingertip using BIOPAC system and BFPWV was obtained using Doppler. Recordings were obtained at three different time points during the menstrual cycle. Analysis was done using repeated measures ANOVA with Bonferroni correction.Result: There was a significant decrease in above parameters p<0.05 during the mid-cycle. Correlation between RI and SI was also significant p<0.05. Conclusion:These findings suggests that the menstrual cycle affects the arterial stiffness and one of the factor is oestrogen. Hence, women are less prone to the incidence of cardiovascular diseases before menopause. Screening for arterial stiffness in a general population, using these indices is valid, economical and reliable.

Background Aortic stenosis (AS) is commonly associated with myocardial and systemic arterial dysfunction. We use a radial artery applanation tonometry (B-Pro) device to characterise the arterial pulse profile of patients with AS and compare them against controls. Methods The B-Pro device was applied on the left radial artery of 117 consecutive patients, where 21 patients had AS. Baseline clinical and echocardiographic characteristics were compared. Differences in arterial pulse pressure profile were quantified by means of univariate and multivariable analyses. Results The group with AS was older (74±14 vs 62±14 years, P<0.001) and had fewer males (38% vs 65%, P=0.025), while other baseline comorbidities were similar. From the arterial pulse profile, a higher systolic peak time (202±45 vs 152±49 ms, P<0.001), lower systolic upstroke gradient (0.35±0.10 vs 0.42±0.14 mm Hg/ms, P=0.022) and longer systolic component of the cardiac cycle (43%±7% vs 39%±5%, P=0.001) were independently associated with AS. Conclusion The B-Pro device allows for real-time microscopic arterial pulse waveform analysis. There are significant differences between the pulse profiles of patients with AS and controls. The prognostic implications of these differences warrant further study.
