Key result
Acute STEMI unmasks concealed Wolff-Parkinson-White syndrome in an asymptomatic patient.
Why the study?
Concealed Wolff-Parkinson-White syndrome revealed after an acute coronary syndrome is rare, with few cases reported in the literature.

Myocardial ischemia or infarction can rarely unmask a concealed Wolff-Parkinson-White syndrome by altering the conduction properties of the AV node or bypass tract.
Wolff-Parkinson-White (WPW) syndrome is a conduction disturbance in which atrial impulses are transmitted to the ventricles by an accessory pathway instead of the normal atrioventricular conduction. The WPW syndrome may either simulate myocardial infarction or mask the electrocardiographic abnormalities of an acute MI. However, concealed WPW revealed after an acute coronary syndrome is rare with few cases reported in the literature. This article reports a case of coronary artery disease with ST-segment elevation in a 57-year-old man, previously asymptomatic, with an initial electrocardiogram showing no conduction abnormalities that subsequently presented with an ECG compatible with WPW.

Castro et al. (2019) conducted a case report in Acute Coronary Syndrome (STEMI) and Wolff-Parkinson-White Syndrome (n=1). Acute coronary syndrome (STEMI) was evaluated on Electrocardiographic changes (WPW pattern). An acute coronary syndrome with ST-segment elevation unmasked a concealed Wolff-Parkinson-White syndrome in a previously asymptomatic 57-year-old man.
