The Relationship Between In-stent Restenosis After Percutaneous Coronary Intervention And The Concentration Of Microabluminuria In The Patients With Coronary Heart Disease

PurposeTo explore the relationship between in-stent restenosis (ISR) after percutaneous coronary intervention (PCI) and the concentration of microabluminuria (MAU) in the patients with coronary heart disease.Methods160 patients who underwent PCI and double check with coronary angiography (CAG) after about one year (mean 10.2±2.5 month) were enrolled; MAU was measured before PCI operation. Based on the secondary CAG results, all the patients were divided into non-in-stent restenosis group (NISR) (as the control group) and in-stent restenosis group (ISR). According to the number of vessels of stent planted, patients in ISR were divided into single-vessel subgroup, double-vessel subgroup, three-vessel subgroup. ResultsCompared to NISR group, the level of MAU in ISR group was significantly high ((60.3629±18.5639)mg/L VS (41.2994±16.6463)mg/L) (t=5.109, P<0.05). In ISR subgroups analysis, the level of MAU in three-vessel subgroup was highest (83.3956±12.1927)mg/L (P<0.05), among three subgroups. And the level of MAU in double-vessel subgroup (57.9529±7.3816)mg/L was higher than that in single-vessel (38.9313±1.9816) mg/L subgroup (P<0.05).ConclusionMAU might be as a useful indicator to predict ISR after PCI.
