Safety study of octogenarian patients receiving non-cardiac surgery within 1 week after coronary computed tomographic angiography / 中华老年医学杂志

ABSTRACT

Objective To compare the safety of octogenarian patients receiving non-cardiac surgery within 1 week versus within 1-3 weeks after coronary computed tomographic angiography(CTA).Methods Octogenarian patients who underwent non-cardiac surgery after coronary CTA in Fujian Medical University Union Hospital,were retrospectively analyzed.All patients were divided into two groupsthose received surgery within 1 week after coronary CTA as group 1 (n =73),those within 1-3 week after coronary CTA as group 2,(n =35).The baseline clinical characteristics,the changes in pre-and postoperative serum creatinine levels (Scr)and estimated glomerular filtration rate(eGFR),and the incidence of acute kidney injury(AKI)were compared between two groups.The revised cardiac risk index(RCRI)score was evaluated for each octogenarian inpatient,and the RCRI sum score for different types of non-cardiac surgery were calculated.Finally,the RCRI sum score of the preoperative risk factors were compared between different types of non-cardiac surgery so as to assess their specifically safety.Results In 108 patients who performed coronary CTA,only one patients developed palpitation and three had injection site pain.All patients receiving different types of non-cardiac operation had low revised cardiac risk index(RCRI ≤ 2).Death was not found.The serum levels of Scr and eGFR were similar between two groups before coronary CTA and after operation(all P＞0.05).Conclusions Octogenarian patients with low preoperative cardiac risk index(RCRI ≤ 2) are safe for performing non-cardiac surgery within 1 week after coronary CTA.
