目的研究冠状动脉支架术后再狭窄与血Lp(a)浓度的关系。方法冠状动脉支架术后4~9个月复查冠状动脉造影(CAG)患者167例,以CAG直径狭窄率≥50%为支架内再狭窄(ISR);以血Lp(a)浓度30mg/dl为界,分为高Lp(a)组与低Lp(a)组。结果 167例247处病变,再狭窄54例87处,再狭窄率32.3%。再狭窄组Lp(a)浓度明显高于无再狭窄组(P<0.05);高Lp(a)组再狭窄率50%,低Lp(a)组再狭窄率23.4%(P<0.01)。结论 Lp(a)是支架再狭窄的重要危险因素。
Objective To study the relationship between restenosis after coronary stenting and serum Lp (a) concentration. Methods A total of 167 coronary artery angiography (CAG) patients were examined at 4 to 9 months after coronary stenting. CAG diameter ≥50% was used as in-stent restenosis (ISR). Serum Lp (a) concentration was 30 mg / Community, divided into high Lp (a) group and low Lp (a) group. Results 167 cases of 247 lesions, restenosis in 54 cases 87, restenosis rate of 32.3%. The Lp (a) concentration in restenosis group was significantly higher than that in non-restenosis group (P <0.05). The restenosis rate was 50% in high Lp group and 23.4% in low Lp group (P <0.01). Conclusion Lp (a) is an important risk factor for stent restenosis.
