Does harmonic analysis of radial artery blood pressure waveforms discriminate hemodynamic differences in patients with T2DM compared to non-T2DM patients?
Harmonic analysis of non-invasively measured radial artery blood pressure waveforms can identify hemodynamic changes associated with Type 2 Diabetes Mellitus, specifically through reduced C1 and C5 amplitude proportions.

Type 2 diabetes mellitus (T2DM) is an important public health issue worldwide. T2DM correlates with cardiovascular disease. Arterial stiffness is also a key factor that can be thought of as a surrogate marker. Nevertheless, it was unclear which harmonic indexes of blood pressure waveforms (BPWs) from subjects’ radial artery pulses would be affected by T2DM. Therefore, the objective of this study was to investigate whether and how harmonic indexes can be used to discriminate hemodynamic differences between patients with T2DM and non-T2DM. This helps us to build objective results no matter who conducts the examination instead of pulse diagnosis in traditional way. We enrolled T2DM and non-T2DM patients as experimental and control groups, respectively, from the Department of Family Medicine in the National Taiwan University Hospital and the Department of Internal Medicine in Taipei’s Veterans General Hospital from December 2017 to January 2019. ANSWatch Model TS-0411 was used to capture the BPWs. Amplitude proportions (Cn values) were calculated from harmonics 1–10 of the BPW using fast Fourier transform. Thirty-two T2DM and 15 non-T2DM patients were enrolled. T2DM patients had significant differences in C1 (p = 0.031) and C5 (p = 0.041). The study suggests that analyzing the harmonic characteristics of non-invasively measured BPW of radial artery may be a potential and easy-to-perform approach to discriminate T2DM-induced hemodynamic changes.
Liao et al. (Wed,) conducted a cross-sectional in Type 2 Diabetes Mellitus (n=47). Harmonic analysis of arterial blood pressure waveform vs. Non-T2DM patients was evaluated on First harmonic amplitude proportion (C1) of the arterial blood pressure waveform (p=0.031). Type 2 diabetes mellitus patients had significantly lower first (p=0.031) and fifth (p=0.041) harmonic amplitude proportions of the arterial blood pressure waveform compared to non-diabetic patients.
