Brief Summary:
Cortisol is essential for survival. The importance of cortisol response is most apparent in patients with partial or complete deficiency of glucocorticoids during stressful events such as illness or surgery.

Condition or disease
Adrenal Insufficiency

Detailed Description:
It is known that cortisol and other stress hormones increase during acute myocardial infarction as well (9-11). Cardiac catheterization is an essential tool for the management of acute coronary syndrome, and for the evaluation of the burden of coronary artery disease in cardiac patients.

Study Type : Observational

patients undergoing elective heart catheterization

Primary Outcome Measures :
  1. cortisol change [ Time Frame: one month ]
    On the day of the procedure a total of 4 venous blood samples for random plasma cortisol level will be obtained. Blood will be drawn at 5 minutes prior to the procedure, at 30 minutes and 60 minutes during the cardiac catheterization. Another sample will be drawn in 3 hours after cardiac catheterization prior to the patients discharge. a cortisol level will be drawn at a "nonstressful" visit
