Key result
A novel noninvasive radial artery pressure pulse waveform measurement technique detected a significant difference in the fourth harmonic between patients with and without myocardial ischemia (p=0.0039).
Why the study?
Does a novel noninvasive measurement apparatus accurately analyze the pressure pulse waveform of the radial artery to diagnose myocardial ischemia in elderly subjects with chest pain?
Population
10 healthy subjects and 60 elderly subjects with a chief complaint of chest pain (total n=70).
Comparison
Novel noninvasive measuring apparatus with a… vs Exercise electrocardiogram.

Radial artery waveform analysis may support noninvasive ischemia detection; hypothesis-generating and should not yet change practice.

p-value: p=0.0039
A novel noninvasive apparatus for measuring the radial artery pressure pulse waveform can differentiate between elderly patients with and without myocardial ischemia.
Tyan et al. (2007) conducted a cross-sectional in Myocardial ischemia (n=70). Noninvasive pressure pulse waveform (PPW) measurement vs. Exercise electrocardiogram (reference standard) was evaluated on Fourth harmonic of the Fourier series (p=0.0039). A novel noninvasive radial artery pressure pulse waveform measurement technique detected a significant difference in the fourth harmonic between patients with and without myocardial ischemia (p=0.0039).
