Purpose of the study
- The predictive value of central aortic pressure and aortic pulse wave velocity (PWV) in a Japanese population is not known. The purpose of this study is to quantify the predictive value of these indices in the determination of cardiovascular risk.
- Recently, a non-invasive method to separate the aortic pressure waveform into the separate ejection pressure wave and reflected pressure wave has become available. With this decomposition method, it is possible to estimate aortic PWV (named AVI). The second objective of this study is to determine if AVI can be a substitute for carotid-femoral PWV (cf-PWV), the current gold standard for aortic PWV measurement.
- To study vascular aging of the Japanese population by evaluating central blood pressure and aortic PWV by age, and compare these values to similar studies done in Caucasian and Chinese patient populations.
- To study the relationship between the magnitude of the aortic reflected pressure wave and the degree of left ventricular (LV) hypertrophy and LV diastolic function.
