This is a retrospective study of patients aged 65 years and older who underwent cardiac and aortic surgery between March 5, 2021 and October 12, 2022 in the operating room of Severance Cardiovascular Hospital to determine the impact of physical frailty as well as nutritional status, emotional dysregulation, and cognitive dysfunction on postoperative outcomes. Physical frailty will be determined by the Clinical Frailty Scale, handgrip strength, and nutritional status, cognitive dysfunction will be determined by the K-MMSE and K-MoCA administered at the preoperative interview, and emotional dysregulation will be determined using the SGDS-K. These were measured during the pre-anesthesia evaluation and only results from patients who agreed to be tested will be used. Nutritional status will be analyzed based on blood test values measured within one month of surgery.
