Data are limited regarding the impact of age and sedation on cardiocerebrovascular disease (CCD) adverse events after GI endoscopy. We investigated the incidence of and risk factors for CCD adverse events after diagnostic GI endoscopy and the impact of age and sedation on these unfavorable outcomes. In this nationwide population-based study, the incidence of and risk factors for newly diagnosed CCD within 14 days after diagnostic endoscopy were analyzed using Health Insurance Review and Assessment Service data from January to December 2015. Among 1,943,150 subjects, CCD adverse events occurred in approximately 2.23% within 14 days after endoscopy. According to the performance of sedation during endoscopy (60.1% nonsedation vs 39.9% sedation, midazolam alone [96.4%]), the incidence rates of CCD adverse events (per 10,000 persons) were 275.8 versus 302.8 for EGD, 116.9 versus 143.8 for colonoscopy, and 230.4 versus 243.2 for EGD + colonoscopy, respectively. On multivariate analysis, older age (70-99 years) and sedation were independent risk factors for CCD adverse events. Regarding CCD risk stratified by age and sedation, older age had a significant impact on CCD adverse events in individuals who underwent EGD only or EGD + colonoscopy, but sedation did not. However, both older age and sedation had considerable influence on CCD adverse events in individuals who underwent colonoscopy only. Sedation during endoscopy was significantly associated with minor but not major CCD adverse events. CCD adverse events were significantly higher for inpatients. CCD adverse events after diagnostic endoscopy were significantly frequent in individuals with older age (70-99 years) and/or sedation during endoscopy. Stratification by age and sedation shows that the impact of these 2 factors on CCD adverse events differs according to endoscopy type.
