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)?
