Task: Answer Verification
Input (English): Question: Does hyperlactemia predict Surgical Mortality in Patients Presenting with Acute Stanford Type-A Aortic Dissection?
Answer: Lactic acidosis, ostensibly as a surrogate for systemic malperfusion, represents a novel, accurate, and easily obtainable preoperative predictor of short-term mortality after attempted AAAD repair. These data may improve identification of patients who would not benefit from surgery.
Output (English): yes
