Diagnostic influence of cardiovascular screening by pocket-size ultrasound in a cardiac unit
Overall, the pUS screening had a sensitivity and specificity with respect to detecting at least moderate pathology of 97 and 93%. Positive and negative predictive values were 93 and 87%, respectively. In the sub-group of subjects with a change in the primary diagnosis following pUS there was no false-negative or false-positive findings.The cardiovascular screening was performed with a pUS, Vscan (GE Vingmed Ultrasound, Horten, Norway).
Conclusion Screening by pUS assessed vascular and cardiac anatomy and function accurately and enabled correction of the diagnosis in 16% of patients admitted to a cardiac unit. In 55% of the participants, the cardiovascular ultrasound screening had important diagnostic influence.
