Value of three-dimensional echocardiography study of left ventricle function correlated to coronary arterial dominance in predicting the outcome of primary percutaneous coronary intervention.

Background: Limited information is available regarding the relationship between coronary vessel dominance and outcome after ST-segment elevation myocardial infarction (STEMI).

Objectives: The study was designed to evaluate the prognostic value of coronary arterial dominance after primary percutaneous coronary intervention (PCI) during hospital stay and at 3 months follow-up regarding cardiac mortality, heart failure, nonfatal myocardial infarction, revascularization, and stroke.

Patients And Methods: The study population consisted of 300 consecutive patients (mean age, 57.
