Abstract:
Objective:To investigate clinical characteristics for in-stent reocclusion lesions after coronary stent implantations in aged patients.Methods:229 patients diagnosed with chronic total reocclusions were recruited from Jan 2005 to Dec 2019 in this retrospective study.According to age, patients were divided into a 40-49 year-old group(n=60), a 50-59 year-old group(n=58), a 60-69 year-old group(n=55), and a 70-80 year-old group(n=56)to examine different lesion characteristics after coronary stent implantations.Results:In the 40-49 year-old group, the 50-59 year-old group, the 60-69 year-old group and the 70-80 year-old group, the rates of multi-vessel reocclusions were 11.6%, 15.5%, 21.8% and 25.0%, respectively( χ2=10.03, P=0.01). For each group, lesions with concurrent proximal and middle coronary reocclusions accounted for 8.3%, 12.0%, 30.9% and 35.7%, respectively( χ2=11.83, P=0.005); Reocclusions with severe coronary calcification accounted for 6.6%, 15.5%, 36.3% and 37.5%, respectively( χ2=11.56, P=0.006); Long coronary reocclusion lesions(36-47 mm)accounted for 15.0%, 17.2%, 21.8% and 25.0%, respectively( χ2=11.56, P=0.007); Coronary reocclusions with diffuse long calcified lesions accounted for 8.3%, 13.7%, 32.7% and 35.7%, respectively( χ2=10.80, P=0.01). Conclusions:The clinical characteristics of in-stent reocclusion lesions after coronary stent implantations include multiple chronic total coronary reocclusions, concurrent proximal and middle coronary reocclusions, heavily calcified coronary reocclusions, long coronary reocclusions and diffuse long calcified coronary reocclusions in aged patients.
