Description
Abstract:
Although preoperative nutritional status is used to predict morbidity and mortality, its effect on the outcomes of acute type A aortic dissection (ATAAD) has not been examined. Thus, the objective was to evaluate the role of preoperative nutritional status in predicting postoperative morbidity and mortality in ATAAD.
Method:
A retrospective analysis of a prospectively maintained database was undertaken for all patients (580) undergoing emergency aortic surgery between May 2004 and February 2023. Preoperative nutritional status was evaluated using Geriatric Nutritional Risk Index (GNRI= 14.89 x serum albumin (g/dL) + 41.7 x body weight (kg) / ideal body weight (kg)). We classified into two groups, GNRI≧92 (group A), GNRI< 92 (group B).
Results:
Of all patients, 410 (70.5%), 170 (29.5%) were classified into group A, group B, respectively. In-hospital mortality rates were not significantly different (8.7% vs. 7.1%, respectively; P=0.69). About incidence of postoperative major morbidities were also not statistically different.
As for 5-year survival rates, 82.4%, 68.9%, were found in groups A and B, respectively, showing a significant difference between the groups (p=0.001). Independent risk factors of late mortality were preoperative nutritional status, preoperative cardiopulmonary resuscitation, previous cardiac surgery, elderly (>80 years), preoperative shock status, myocardial malperfusion, visceral malperfusion.
Conclusion:
Preoperative assessment of nutritional status using GNRI is an independent factor in the long-term prognosis of acute aortic dissection. This assessment method is simple to perform preoperatively and may provide useful information for predicting the postoperative mortality and morbidity in elderly patients.
