The acute coronary syndromes [unstable angina (UA) and acute myocardial infarction (AMI)] are more dangerous than other ischemic heart diseases (IHD) due to acute morphological changes in atherosclerotic plaques which cause (acute ischemia) severe imbalance between myocardium demand and oxygen supply. In this study we investigated adiponectin hormone, creatine kinase(CK), lactate dehydrogenase(LDH), malondialdehyde(MDA), nitric oxide(NO), superoxide dismutase(SOD), and glutathione(GSH)  in patients with unstable angina and acute myocardial infarction, This study has been carried out on 100  patients with unstable angina and acute myocardial infarction and 50 healthy subjects. the study shows that there is a significant difference in the concentration of serum Adiponectin, CK, LDH, MDA, NO, SOD, and GSH between (controls, AMI and UA ) in the (male and female )  groups (p≤0.05).
