ABSTRACT
BACKGROUND:
Unique electrocardiographic findings are rarely observed in acute coronary syndrome (ACS) with a culprit left anterior coronary artery (LAD). The aim of this study was to assess the epidemiological features and prognostic impact.METHODS:
This study was designed as an observational study. A total of 641 patients with a culprit lesion in the left main trunk or LAD were extracted from a cohort of 1776 ACS patients. The primary endpoint was mortality, comparing patients presenting with unique electrocardiogram patterns, specifically the de Winter pattern or Wellens' syndrome (type A or B), upon hospital arrival, with those presenting common electrocardiogram patterns.RESULTS:
A unique electrocardiogram was observed in 7.0% (n = 45; 2 with de Winter pattern, 14 with Wellens' type A and 29 with type B). Compared to patients with a common pattern, cardiogenic shock at hospital arrival were rare in patients with a unique pattern (0% vs. 8.4%, P = 0.04), and percutaneous coronary intervention was primary revascularization strategy in all groups (95.6% vs. 98.2%). The mortality rates were similar between the two groups over a median 565 days of observation period (13.3% vs. 15.7%, P = 0.43), with 0% in Wellens' type A, 13.8% in type B, and both patients with the de Winter pattern died.CONCLUSION:
The de Winter pattern or the Wellens syndrome was found in 7.0% of cases with ACS. They had similar mortality rates compared to those with a common pattern, although the de Winter pattern was identified in only 2 patients.Mots clés
