Core Tip
Core tip: This study was obtained from the data of 1,296 patients with acute coronary syndrome who presented to the emergency department with chest pain between January 2014 and December 2018. In the R to S ratio (RSR) > 1 group, the left ventricular ejection fraction was lower, while the gensini scores and troponin values in the 0, 6th, and 12nd hours were significantly higher. The RDW value was high in the group with RSR < 1. In the group with RSR > 1, complications that occur after anterior myocardial infarction, three-vessel disease and mortality were high, and the prognosis was worse. The most common acute anterior myocardial infarction was observed.
