ABSTRACT

INTRODUCTION Primary angioplasty has been shown to improve survival as compared to thrombolysis, mainly due to restoration of TIMI flow in a larger percentage of patients (up to 90%). However, it has been described as suboptimal myocardial reperfusion in a relatively large proportion of patients (ranging between 20% and 40%) despite optimal restoration of epicardial perfusion (TIMI 3 flow) (1). ST-segment resolution is a cheap and easy method to assess myocardial reperfusion (2). The aim of this chapter is to review the current role of electrocardiogram (ECG) and ST-segment resolution in the assessment of optimal reperfusion in primary angioplasty.
