201 consecutive patients undergoing coronary stent implantation across 11 centers in Argentina
Comparison
New cobalt chromium bare-metal stent design
Design
Prospective, multicenter, observational controlled registry
Follow-up
Mean of 376 ± 18.1 days

Implication
Residual ERACI ≤5 may identify low-risk patients after novel bare-metal stenting; leaves open prospective validation before guiding complex CAD revascularization.
Structured PICO
P
Population
201 consecutive patients undergoing coronary stent implantation in 11 centers in Argentina. Inclusion criteria: multiple-vessel disease and/or unprotected left main disease, acute coronary syndromes (ACS) with at least one severe (⩾70%) stenosis in any major epicardial vessel. Exclusion criteria: in-stent restenosis, protected left main stenosis, or impossibility to receive dual-antiplatelet therapy.
I
Intervention
New cobalt chromium bare-metal stent (BMS) design
O
Outcome
Major adverse cardiac events (MACE) including cardiac death, myocardial infarction (MI), and target lesion revascularization (TLR) at 1 yearcomposite
A novel cobalt chromium bare-metal stent demonstrated a low 1-year MACE rate of 10.4% in an all-comers population with complex coronary disease.
