Key result
Non-invasive radial pulse wave assessment (Rad dP/dt) was closely related to mitral regurgitation dP/dt (r=0.75, p<0.001), serving as a reproducible peripheral criterion of LV systolic performance.
Why the study?
Does non-invasive radial pulse wave assessment (Rad dP/dt) accurately correlate with echocardiographic parameters of left ventricular systolic performance in patients with heart failure?
Observational (n=360)

Effect estimate: r=0.75
p-value: p=<0.001
Non-invasive radial pulse wave assessment (Rad dP/dt) is a highly feasible and reproducible peripheral surrogate marker for left ventricular systolic performance in heart failure patients.
No takes yet. Share an insight, caveat, or question.
May support radial pulse wave assessment as feasible LV systolic surrogate in HF; hypothesis-generating, needs prospective validation.
Tartière et al. (2007) conducted an observational in Heart failure (n=360). Radial pulse wave assessment (Rad dP/dt) vs. Echocardiography parameters was evaluated on Correlation between Rad dP/dt and MR dP/dt (r=0.75, p=<0.001). Non-invasive radial pulse wave assessment (Rad dP/dt) was closely related to mitral regurgitation dP/dt (r=0.75, p<0.001), serving as a reproducible peripheral criterion of LV systolic performance.
