Abstract

Background Incomplete ST-segment resolution (STR) is a marker of impaired myocardial perfusion and adverse clinical outcome after primary percutaneous coronary intervention (PPCI). Synergy between percutaneous coronary intervention with TAXUS and cardiac surgery score II (SS-II) has been developed combining anatomical and clinical variables. The aim of the present study was to evaluate the SS-II as a predictor of incomplete STR in patients with ST-segment elevation myocardial infarction (STEMI) treated with PPCI. Patients and methods The present study prospectively included 100 patients with STEMI treated with PPCI. SS-II was determined in all patients. The sum of ST-segment elevation was measured from standard 12-lead ECG obtained on admission and from a second ECG recorded 60 min after PPCI. STR resolution was defined as either complete (≥50%) or incomplete ( Results Patients in the negative STR group were older, had higher prevalence of peripheral vascular disease, lower creatinine clearance (CrCl), higher peak troponin, lower ejection fraction and a higher SS-II (P value = Conclusion SS-II is an independent predictor of incomplete STR in patients with STEMI treated with PPCI.
