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.

Primary Outcome Measures:
  • cortisol change [ Time Frame: one month ] [ Designated as safety issue: No ]
    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

Estimated Enrollment: 23
Study Start Date: March 2013
Estimated Study Completion Date: June 2014
Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
patients undergoing elective heart catheterization

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.


Ages Eligible for Study:   20 Years to 90 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

30 males and females, age 20-90 years who are scheduled for elective cardiac catheterization procedure.


Inclusion Criteria:

  • Patients undergoing elective cardiac catheterization, who are willing and able to give consent.

Exclusion Criteria:

  • • Patients with .primary or secondary adrenal insufficiency.

    • Patients taking steroids in the doses equivalent of at least 5 mg of prednisone daily for more than 3 weeks in the previous year.
    • Patients undergoing cardiac catheterization in the setting of acute coronary syndrome, eg. STEMI, NSTEMI and unstable angina.
    • Patients with low albumin level (<3.5 g/dL)
