Abstract
AIM: The effect of changes in physical performance during the perioperative period on the prognosis of older patients undergoing cardiac surgery has not been studied in detail. This study aimed to investigate the effect of perioperative changes in physical performance on the prognosis of older patients undergoing cardiac surgery. METHODS: A total of 223 patients were graded as either frail or non-frail according to a cutoff score of 9 based on preoperative Short Physical Performance Battery scores. The non-frail patients were further grouped into high, recovery, or decreased score groups, depending on their score at the time of discharge compared with preoperative scores. Basic characteristics, preoperative and postoperative clinical data, 6-month post-discharge mortality, readmission rates, and vital function (Kihon Checklist scores) were compared. RESULTS: In total, 16.1% of patients were in the frail group, while 18.4%, 35.4%, and 30.1% were in the decreased, recovery, and high score groups, respectively. The Short Physical Performance Battery scores in the decreased group were significantly lower at discharge, and the rate of readmission was significantly higher (17.7%, P < 0.05). In addition, the Kihon Checklist scores were significantly lower than the preoperative scores (5.7 ± 4.0 vs 8.6 ± 5.5, P < 0.05). CONCLUSIONS: Both preoperative and postoperative physical performance must be considered when predicting the prognosis of older patients undergoing cardiac surgery.
