Admission lactate ≥1.8 mmol/L was associated with higher 30-day mortality in STEMI; hypothesis-generating for risk stratification and requires prospective validation.
Are admission arterial lactate levels associated with 30-day mortality and clinical presentation in patients with STEMI?
Point-of-care measurement of arterial lactate at admission in STEMI patients can improve acute risk stratification, with levels ≥ 1.8 mmol/L associated with higher 30-day mortality.
Vermeulen et al. (2010) studied this question.
