Does A Low 6-Minute Walk Distance Predict Elevated Postoperative Troponin?

Our study of 100 major vascular and renal transplant patients evaluated the 6-minute walk test (6MWT) as an indicator of perioperative myocardial injury, using troponin as a marker. Using logistic regression and the area under the receiving operator characteristic curve, we compared the 6MWT to the Revised Cardiac Risk Index and metabolic equivalents. Only the 6MWT was associated with elevated postoperative troponins (95% CI, 0.98–0.99). However, the 6MWT area under the receiving operator characteristic curve (0.71 [95% CI, 0.57–0.85]) was not different from the Revised Cardiac Risk Index (P = .23) or metabolic equivalents (P = .14). The 6MWT may have a role in cardiac risk stratification in the perioperative setting. Accepted for publication January 16, 2018. Funding: None. The authors declare no conflicts of interest.
