| アブストラクト | BACKGROUND: The Revised Cardiac Risk Index (RCRI) has been incorporated into preoperative assessment guidelines and is used for simple preoperative screening; however, validation studies within large populations are limited. Moreover, although sex differences in perioperative risk are recognized, their effect on the performance of the RCRI remains unclear. Therefore, in this study we evaluated whether sex differences exist in the risks within the strata classified by the RCRI. METHODS AND RESULTS: The Japan Medical Data Center database based on claim and health examination data in Japan between January 2005 and April 2021 was used. A total of 161,359 noncardiac surgeries performed during hospitalization were analyzed. The main outcome was the 30-day risk of major adverse cardiovascular events. Although there was no significant sex difference among those with an RCRI >/=1, males had a significant hazard rate (1.32 [95% confidence interval, 1.03-1.68]) of postoperative events in the low-risk group with an RCRI of 0. However, this significant difference was not detected in the population excluding those who underwent breast and gynecological surgeries. CONCLUSIONS: The RCRI achieved reasonable risk stratification in validation using Japanese real-world data regardless of sex. Although further detailed analysis is necessary to determine the sex differences, the validity of using the RCRI for screening purposes is supported at this stage. |
