Do personalized physiologic flow waveforms improve wave reflection estimates compared to triangular flow waveforms in adults?
Personalized physiologic flow waveforms offer a more robust alternative to triangulation for estimating wave reflection when aortic flow cannot be measured.
We demonstrate that triangular flow waveforms overestimate wave reflection indices, particularly at higher central pulse pressures independent of age or carotid-femoral pulse wave velocity. In contrast, personalized physiologic flow waveforms provide equivalent wave reflection estimates as measured flow waveforms, thereby offering a more robust alternative to triangulation when aortic flow cannot be measured.
