The association between hyperglycaemia and elevated troponin levels on mortality in acute coronary syndromes

Diabetes is associated with increased cardiovascular morbidity and mortality. We studied the relationship between hyperglycaemia, troponin I concentrations and one-year mortality in 498 subjects admitted to hospital with an acute coronary syndrome. The proportion of deaths was higher in those with hyperglycaemia (random glucose > 11. 1 mmol/L) compared to those without (27% and 12%, respectively, Chi-squared test = 9. 84, p=0. 002). There was a difference in troponin I concentration on admission between those patients who were alive and dead (median and interquartile range 0. 14 [0 to 3. 90] and 2. 98 [0. 23 to 18. 53] respectively, p
