To investigate the assocaition between reticulated platelets (RPs) and long-term outcomes of premature coronary artery disease (PCAD) patients after percutaneous coronary intervention (PCI). Methods? ?We recruited 300 PCAD patients (males aged <45 years and females aged <55 years at the onset of coronary artery disease) and 250 controls with normal coronary angiographic results. RPs percentage was assessed using a direct, whole blood, dual-labeling flow cytometric method. We evaluated the association of RPs with long-term major adverse cardiac events (MACE) after 24-month follow-up and coronary in-stent restenosis (ISR). Results?? There were 20 cardiac events (6.7%) during the 24-month follow-up. PCAD and control groups differed significantly in smoking, diabetes, family history, and history of heart failure. RPs were significantly higher in PCAD group than in control group (P<0.05). The incidence of ISR in RPs>10% group was significantly different from that in RPs 6%-8% group (P<0.05). Cox proportional hazard regression analysis of RPs>10% was an independent variable in predicting MACE (HR=2.58, 95% CI: 1.12-5.35, P<0.01). Kaplan-Meier event survival curve showed that the incidence of cardiovascular events in RPs>10% group was higher than that in RPs <10% group. Conclusion? ?RPs are an independent molecular marker for predicting the long-term outcomes in PCAD after PCI. RPs>10% are associated with ISR in patients with PCAD after PCI, and the incidence of MACE is increased
