Objectives: The prognostic value of residual SYNTAX score (rSS) has been observed in different patient groups. However, its prognostic value has not been compared in patients with ST segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI).

Methods: A total of 208 patients meeting the eligibility criteria were included in the study. Complete revascularisation (CR) was defined as rSS = 0 and incomplete revascularisation (IR) was defined as rSS ≥ 1.

Results: Among the sample, 78 patients (33.3%) were included in the CR group and 130 patients (67.7%) in the IR group. One patient (1.3%) in the CR group and 8 patients (6.2%) in the IR group died by day 30 (p < 0.01). The incidence of stent thrombosis, recurrent myocardial infarction (MI) and target lesion revascularisation (TLR) was similar between the two groups. During follow-up (mean 28.8 ± 7.1 months), 2 patients (2.6%) from the CR group and 10 (7.7%) patients from the IR group died (p > 0.05). The incidence of recurrent MI (18.5% vs. 7.7%; p < 0.01) and major adverse cardiovascular events (MACE) (24.6% vs. 7.7%; p < 0.01) were significantly higher in the IR group.

Conclusion: rSS, which is an indirect marker of incomplete revascularisation, was independently correlated with recurrent MI and MACE after STEMI.
