Screening Tests for Determining Risk of Left Ventricular Systolic Dysfunction

Purpose: To screen a patient for evidence of left ventricular systolic dysfunction using the algorithm of Nielsen et al.

Description

Nielsen et al used a small battery of screening tests to determine a patient's risk of left ventricular systolic dysfunction. This can help identify a patient for whom additional testing is warranted. The authors are from Copenhagen University Hospital and Odense University Hospital in Denmark.


 

Parameters:

(1) Does a 12-lead ECG show QRS and/or ST-T changes?

(2) Is the resting supine heart rate in beats per minute greater than the diastolic blood pressure in mm Hg?

(3) Is N-terminal atrial natriuretic peptide elevated (> 0.8 nmol/L; mean plus 2 SD was 0.77 nmol/L)?
