Natural History, Prognosis and Complications
The presence of Wellens' syndrome carries significant diagnostic and prognostic value. All patients in the De Zwann's study with characteristic findings had more than 50% stenosis of the left anterior descending artery (mean=85% stenosis) with complete or near-complete occlusion in 59%. In the original Wellens' study group 75% of those with the typical syndrome manifestations had an anterior myocardial infarction. Sensitivity and specificity for significant (more or equal to 70%) stenosis of the LAD artery was found to be 69% and 89% respectively with positive predictive value 86%.[1]
