摘要：Photoplethysmogram is a non-invasive optical technique that is widely used to measure the variation of blood volume by using infra-red light. It is a potential technique for early screening of atherosclerosis and lipid profiling. An intervention program of 12 weeks was done in monitoring the changes in lipid profile in the blood vessel and the morphological changes in the PPG signal. A total of 35 young men aged 20 to 40 years old were selected and the subjects were leading a sedentary lifestyle with less than 5000 steps of walking per day and having two or more CV risk factors. The subjects recruited were divided into two groups that were Group P (n=19) and Group C (n=16). Parameters that were recorded along the intervention were vascular age and fitness index (PPGF) from PPG, lipid profiling, pulse wave velocity (PWV), body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP). A first derivative of PPG was done in determining the crest time (CT). The data were recorded at three different stages, baseline, 6th week and 12th week. The morphological analysis clearly differentiates the subjects with different combination of lipid profiles. Results show that there is a significant improvement on PPGF and CT at the first 6 weeks whereas on the lipid profiling of TG, HDL and LDL shows consistent improvement throughout the 12 weeks intervention. The intervention for health maintenance has potential in adopting walking as an exercise and PPG device as a health measurement tools. The identified morphological classification will need further analysis and automated classification to establish a non-invasive low cost optical based screening method for lipid profiling in future.
