Abstrakt: Objective: To compare the incidence of myocardial damages diagnosed following vascular surgery using the cardiac troponin I measurement technique and conventional methods.
Study Design: Prospective epidemiological study.
Patients: Fifty-four patients who underwent surgery for either aneurysmal disease in 28 cases or occlusive aortic disease in 26 cases.
Methods: Plasma concentration of cardiac troponin I (significant at a concentration > 1.5 ng.mL-1) was measured by immunoenzymofluorimetry on the second and fifth postoperative days. Conventional monitoring methods included daily electrocardiogram (ECG), enzymatic assay of total-PCK, and measurement of plasma levels of the MB isoenzyme of phosphokinase creatine (MB-PCK) (significant at > 1 ng.mL-1 and RI > 1.5).
Results: The cardiac troponin I measurement technique allowed the diagnosis of minor myocardial damages during the postoperative period in five patients, whereas with the conventional methods (clinical signs. ECG, and MB-PCK) only three myocardial lesions were diagnosed.
Conclusion: The cardiac troponin I measurement technique allows diagnosis of minor myocardial damages following vascular surgery. Conventional methods underestimate the incidence of these damages.
