Objective:  To determine the incidence of normal coronaries on cardiac catheterization and its pattern of occurrence according to sex and age.    Methods: This is a retrospective study conducted at Queen Alia Heart Institute in Amman-Jordan during the period 2006 to 2011. A total number of 5000 adult patients who had coronary angiography for chest pain, which were reviewed looking for the presence of normal coronaries, its frequency among males and females and its occurrence  according to age groups.   Results:The overall incidence of normal coronaries on cardiac catheterization was 17.3%, with almost equal ratios for males and females (53.9% and 46.1% respectively). Womenin the age group 50 – 59 years was the commonest category (33.7%) to have normal coronary angiography, whereas the commonest age group for males was 40 to 49 years. Patients above 70 years of age were very less commonly to have normal coronaries (only in 8.5%).   Conclusion:  Normal coronaries on cardiac catheterization is a recognized finding in both men and women.
