Abstract

Acute myocardial infarction with ST segment elevation (STEMI) is a life threatening condition. Mechanical reperfusion with primary percutaneous coronary intervention (PPCI) can limit or even stop the infarction process. Prediction of the culprit lesion location through the pre-PPCI ECG is known to shortening door-to-balloon time. This research is a descriptive study with a cross-sectional approach. The data source is secondary data. The sample in this study was STEMI patients underwent PPCI in Abdul Wahab Sjahranie Hospital on July-December 2018 period that match with the inclusion criteria.There were 35 patients as sample. Culprit lesion localization in LAD was found in 23 cases (65.7%), RCA was 10 cases (28.6%), and LCX was 2 cases (5.7%). No patient was found with culprit lesion located in LMCA. Complete ST segment resolution (≥70%) was found in 4 cases (11.4%), partial resolution (30-70%) was 13 cases (37.1%), no resolution (<30%) was 16 cases ( 45.7%), and increased ST segment elevation was 2 cases (5.7%). TIMI flow 3 was found in 33 cases (94.3%), TIMI flow 2 in 2 cases (5.7%) and no cases were found with TIMI flow 1 or 0.Culprit lesion are frequently located in LAD. The distribution of the culprit lesion locations based on risk factors of the patients shows LAD as the most common location for culprit lesions in patients with STEMI. PPCI succeeded angiographycally but was unsuccessful based on ECG.
