BACKGROUND: Patients with non-ST-elevation myocardial infarction (NSTEMI) have worse long-term prognoses than those with ST-elevation myocardial infarction (STEMI). HYPOTHESIS: It may be attributable to more extended coronary atherosclerotic disease burden in patients with NSTEMI. METHODS: This study consisted of consecutive 231 patients who underwent coronary intervention for myocardial infarction (MI). To assess the extent and severity of atherosclerotic disease burden of non-culprit coronary arteries, two scoring systems (Gensini score and synergy between percutaneous coronary intervention with Taxus and cardiac surgery [SYNTAX] score) were modified by subtracting the score of the culprit lesion: the non-culprit Gensini score and the non-culprit SYNTAX score. RESULTS: Patients with NSTEMI had more multi-vessel disease, initial thrombolysis in myocardial infarction (TIMI) flow grade 2/3, and final TIMI flow grade 3 than those with STEMI. As compared to STEMI, patients with NSTEMI had significantly higher non-culprit Gensini score (16.3 ± 19.8 vs. 31.2 ± 25.4, p < 0.001) and non-culprit SYNTAX score (5.8 ± 7.0 vs. 11.1 ± 9.7, p < 0.001). CONCLUSIONS: Patients with NSTEMI had more advanced coronary atherosclerotic disease burden including non-obstruction lesions, which may at least in part explain higher incidence of cardiovascular events in these patients.
