ABSTRACT=A cross sectional  study  was conducted  in El-Shaab Hospital, Sudan to investigate  zinc and copper in  angiographicaly-defined obstructive (CAD) in patients undergoing elective coronary angiography. 
One hundred and forty two patients were enrolled. Socio-demographic, medical characteristics were gathered using a questionnaire. Glucose, lipid, zinc, copper levels were investigated using the suitable lab methods.
Out of 142, 102 (71.8%)  and 40 (28.2%) patients had CAD and patent coronary arteries, respectively. There was  no significant  difference in  the median ( inter-quartiles) zinc [118.5 (97.2 - 151.0) vs. 130.0 (106.0 - 174.0) µg/ml, P = 0.120],  copper  [150.6 (125.0 - 183.0) vs 158(132.0- 180.0) µg/mL, P = 0.478] levels  between the patients with  CAD and patent coronary arteries. Likewise, in linear regression analysis there was no  associations between  zinc,  copper  levels and CAD. 
Thus  the current study  failed to  show a significant association  between  zinc, copper levels and CAD .
