The Prognostic Role of Residual SYNTAX Score in the Recovery of Erectile Function Following Myocardial Infarction Treated with Percutaneous Coronary Intervention

BACKGROUND: Erectile dysfunction (ED) and acute coronary events are closely linked, yet the trajectory of ED following percutaneous coronary intervention (PCI) remains incompletely understood. The residual SYNTAX score (RSS) quantifies incomplete revascularization and is an established prognostic tool in cardiology; however, its role in erectile function recovery after myocardial infarction (MI) is unclear. OBJECTIVES: To evaluate whether RSS predicts recovery of erectile function after MI treated with PCI. MATERIALS AND METHODS: In this prospective cohort study, 82 men aged 40-70 years who underwent PCI for MI were evaluated. ED was assessed using the International Index of Erectile Function-5 (IIEF-5) at baseline (after recovery from PCI, reflecting erectile functions before MI), and at 3 and 6 months. ED was defined as an IIEF-5 score ≤21. Patients were stratified according to RSS (
