Abstract
We found a high white blood cell count (>11,000/mul) to be of additive prognostic value to high troponin-I levels in predicting risk of recurrent nonfatal myocardial infarctions and all-cause mortality in patients who present with acute coronary syndromes and non-ST-elevation myocardial infarctions. A high troponin-I level or white blood cell count increased the odds ratio of an event to 2.2 (95% confidence interval 1.0 to 4.73, p = 0.05), but high values for the 2 markers increased the odds ratio to 4.5 (95% confidence interval 1.42 to 14.21, p = 0.01).
