[Usefulness of rapid bedside assay of cardiac troponin I and creatine phosphokinase-MB in acute ischemic coronary syndromes].

Recently, a rapid bedside assay for quantitative determination of cTI and CPK-MB has been developed that provides a positive or negative result in 10 to 15 minutes allowing for a better therapeutic approach. The objective of our study was to validate the diagnostic usefulness of cardiac troponin I in patients with chest pain. We determined sensitivity, specificity, positive and negative predictive values in 40 patients that arrived to the hospital with chest pain.
