Cognition and progress of de Winter electrocardiogram pattern / 中南大学学报(医学版)

The de Winter electrocardiogram pattern is an acute ST-segment elevation myocardial infarction equivalent, however this specific electrocardiogram change is easily ignored by clinicians. The de Winter electrocardiogram pattern in patients with acute chest pain mostly indicates sub-complete or complete occlusion of the left anterior descending or the diagonal branch. Patients with acute chest pain and such electrocardiographic finding should undergo emergency coronary angiography immediately to determine the coronary condition, and reperfusion therapy should be performed as soon as possible to reduce the incidence of adverse cardiovascular events.

Clinical characteristics of patients with the de Winter electrocardiogram pattern / 中南大学学报(医学版)

OBJECTIVES@#To explore the electrocardiogram manifestations and clinical characteristics of patients with the de Winter electrocardiogram pattern.@*METHODS@#This retrospective study was performed on acute coronary syndrome (ACS), patients with culprit lesion in left anterior descending branch (LAD), who admitted to Yongchuan Hospital of Chongqing Medical University from August 2017 to October 2018. Patients were categorized into those with or without the de Winter electrocardiogram pattern. The characteristics of de Winter electrocardiogram were analyzed by the clinical data of the patients.@*RESULTS@#Among 230 patients with left anterior descending branch lesion, 14 (6%) had the de Winter electrocardiogram pattern. Compared with the control group, patients with de Winter electrocardiogram pattern were younger [(53.86±10.26) years old vs (67.20± 11.60) years old @*CONCLUSIONS@#The de Winter electrocardiogram pattern syndrome in patients with acute chest pain mostly indicates that the left anterior descending or the diagonal branch is subtotal or completely occluded, which is a special ST-segment elevation myocardial infarction equivalent and should attract the clinicians' extensive attention.
