If we can to avoid the occurrence of risk factors and assess the degree of arterial stiffness that we can prevent cardiovascular disease place. Our laboratory previous design of the two arteriosclerosis measuring instruments (PWV-DVP and PWV-DVPE), respectively, by measuring hand-foot and ear-hand pulse wave velocity, the two instruments has been proven and existing atherosclerosis measurement instrument associated with the clinical sciences. Because of the measured reference point, there will be underestimating the degree of atherosclerosis the circumstance. In order to solve this problem, our laboratory research the ECG R-wave peak as the anchor point, and then combined volume of six groups of light sensing circuit made of six channels pulse wave velocity measuring device, and this system has proved in healthy people who have good results and reproducibility. But the equipment did not compare with the other instruments in the hospital and did not apply to the patients. We used a six-channels measuring instrument of atherosclerosis in healthy people and patients to do some studies. Separately with the Cardio-ankle vascular index and PWV-DVP the similar instrument makes the relevant comparison in the healthy subjects to test the relevance of parts, the study found the finger and the site of the toes has correlation in PWV values. In the trend part of the experimental, we found that when the ear parts of PWV higher, the hand and the foot PWV will be relatively high. Separately with the Initima-Media Thickness and PWV-DVP, the similar instrument makes the relevant comparison in the cardiovascular disease patients to test the relevance of parts, the study found position in the ears have a good relationship, we also found a six-channels measuring instrument indeed improved PWV-DVP and PWV-DVPE's missing in the assessment of atherosclerosis. In future, our lab will use this system in diabetic patients on the rain-depth analysis. Hsien-Tsai Wu 吳賢財 2010 學位論文 ; thesis 69 zh-TW |
