[Increase of creatine kinase mb isoenzyme out of a context of acute myocardial infarct].

The increased serum level of the MB isoenzyme of creatine kinase is a very useful test for the diagnosis of acute myocardial infarction. However, there are several situations of false positives for this test that are scarcely mentioned in the standard medical references. We report a case of prostate carcinoma with a high serum creatine kinase BB fraction.

[Electrocardiographic changes after coronary angiography: effect of the contrast media used].

Unlabelled: Prospective study to evaluate the influence of 2 different iodine contrasts (used in coronariography) on the electrocardiographic changes recorded after intra-coronary injection.

Material And Methods: Sixty-six patients (pts) - 50 men and 16 women - 59 +/- 4 years underwent coronariography to confirm and/or evaluate coronary artery disease (CAD). Group I (33 pts) received a hyperosmolar contrast; group II received a low osmolarity contrast.
