Abstract

Fifty-seven (57) patients with suspected acute myocardial infarction and non-conclusive EKG, who went to the Emergency Room of the Cardiology and Cardiovascular Surgery Institute, were selected for qualitative determination of Myoglobine and CK MB in addition to total quantitative determination of creatine kinase. The supra imbalance of ST segment lenght under 2mm in precordial lead and under 1mm in limb liad as well as total left bundle branch block were the most frequent disorders that hindered the electrical diagnosis. The evolving infarction diagnosis was confirmed in 30 patients. Sensitivities of Myoglobine and CK MB were 60 % and 70 % respectively, specificity 59 and 57 % respectively, positive prognostic value 57 and 47 % and negative prognostic value 70 and 78 % respectively. The results of qualitative and quantitative enzimes were obtained in 47 min and 115 min respectively. Time interval from the starting of symptoms to the obtention of results using the qualitative enzime kit was 240 min and that of the total creatine kinase was 378 min.
