BACKGROUND: In-stent neoatherosclerosis (ISNA) is an important reason for stent failure. High lipoprotein (a) [Lp (a)] level is an independent predictor of in-stent restenosis (ISR). To date, the relationship between the level of serum Lp (a) and the incidence rate and vulnerability of ISNA has never been verified.
METHODS: A total of 119 patients with 125 drug-eluting stent ISR lesions who underwent percutaneous coronary intervention guided by optical coherence tomography were enrolled in this study. According to their Lp (a) level, the patients were divided into two groups [high Lp (a) group ≥ 30 mg/dL, n = 47; or low Lp (a) group < 30 mg/dL, n = 72]. The clinical baseline, angiographic characteristics, and optical coherence tomography data of both groups were recorded and analyzed.
RESULTS: No significant differences in clinical and angiographic characteristics were found between the two groups (P > 0.05). The incidence rate of ISNA in the high Lp (a) group was significantly higher than that in the low Lp (a) group (94.0% [n = 47] vs. 52.0% [n = 39], P < 0.001). The incidence rate of thin-cap fibroatheroma in ISR lesions was significantly higher in the high Lp (a) group than in the low Lp (a) group (42% [n = 21] vs. 5.3% [n = 4], P < 0.001).
CONCLUSION: A high Lp (a) level is associated with the high incidence rate and plaque vulnerability of ISNA.
