Conclusion

In patients undergoing non-cardiac surgery, a peak postoperative hsTnT measurement of ≥20 ng/L and an absolute change of ≥5 ng/L during the first 3 days after surgery was significantly associated with 30-day mortality. These data suggest that unrecognized heart injuries may account for about 25% of the deaths within the first 30 days after non-cardiac surgery, and that a better management of ischemic heart injury detected by hsTnT has the potential to prevent many of the deaths after non-cardiac surgery.

During the press conference, the VISION study was applauded for informing physicians about what are normal and what are higher values obtained with the newer hsTNT tests. For patients it is important to better know their risks.

In current clinical practice, hsTNT is not commonly measured, which means ‘low-hanging fruit that we’re ignoring’. Dr. Devereaux suggests that hsTNT is measured, and he advises that patients with elevated hsTNT values be seen by a specialist. Moreover, statin and aspirin therapy may be considered. He noted that the VISION study concerns observational data, but the study population had coronary disease, and evidence exists that statins and aspirin provide benefit. Dr. Devereaux proposes a pragmatic approach to measure hsTNT in anyone over 65 years old, and in those over 45 with known CVD.
