Implication

Radial model 2.3 may enhance detection of localized LV wall motion abnormalities; challenges area model preference but remains hypothesis-generating.

Structured PICO

Does radial model 2.3 improve the detection of localized left ventricular wall motion abnormalities compared to other quantitative models in patients with myocardial infarction?

Population

44 subjects (14 normals, 12 patients with anteroseptal infarction, 10 with inferior infarction, and 8 with posterolateral infarction) undergoing biplane cineventriculograms

Intervention

Radial model 2.3 for assessment of localized left ventricular wall motion abnormalities

Comparator

Other quantitative models (including 8 half-axis models, 2 other radial models, and 8 segmental area models such as area model 3.5)

Outcome

Sensitivity for recognition of myocardial infarction at 90% specificitysurrogate

Radial model 2.3 is the most accurate quantitative model for assessing localized left ventricular wall motion abnormalities, challenging previous literature.
