Key result
Systolic AVPD measurements were significantly lower than conventional total AVPD measurements in all groups (P<0.001), indicating the conventional method overestimates true systolic function.
Why the study?
Does systolic AVPD measurement differ from conventional total AVPD measurement in assessing ventricular systolic function in healthy subjects and patients with heart disease?
Population
n=58, comprising 28 young healthy males and 30 patients with heart disease
Comparison

Conventional AVPD may overestimate systolic function; this Level 4 cross-sectional finding leaves open the need for updated references and prospective validation.
Observational (n=58)
Does systolic AVPD measurement differ from conventional total AVPD measurement in assessing ventricular systolic function in healthy subjects and patients with heart disease?
p-value: p=<0.001
The conventional total AVPD method overestimates amplitude in relation to true systolic function compared to the novel systolic AVPD method, suggesting a need to update reference values.
Carlhäll et al. (2004) conducted an observational in Heart disease and healthy subjects (n=58). Systolic AVPD measurement vs. Total AVPD measurement (conventional method) was evaluated on Atrioventricular plane displacement (AVPD) amplitude (p=<0.001). Systolic AVPD measurements were significantly lower than conventional total AVPD measurements in all groups (P<0.001), indicating the conventional method overestimates true systolic function.
