Key result
A pocket-size imaging device added to physical examination increased the diagnosis of cardiac abnormalities from 38.2% to 69.7% (P<0.0001), with an overall sensitivity of 91% and specificity of 76%.

Does the addition of a pocket size imaging device to physical examination improve the diagnosis of cardiac abnormalities in non-cardiologic outpatients?
Absolute Event Rate: 69.7% vs 38.2%
p-value: p=<0.0001
The addition of a pocket-size ultrasound device to physical examination significantly improves the detection of cardiac abnormalities in non-cardiologic outpatients, though accuracy depends heavily on operator experience.
Galderisi et al. (2010) conducted a cross-sectional in Cardiac abnormalities in non-cardiologic outpatients (n=304). Pocket size imaging device vs. Physical examination was evaluated on Diagnosis of cardiac abnormalities (p=<0.0001). A pocket-size imaging device added to physical examination increased the diagnosis of cardiac abnormalities from 38.2% to 69.7% (P<0.0001), with an overall sensitivity of 91% and specificity of 76%.
