Objectives: 1. Aims to find out the frequency of coronary artery dominance incidence by the angiographic method. 2. Association of coronary artery dominance with coronary artery disease through Gensini scoring.
Design: Retrospective record review.
Setting: Single-center, retrospective record review carried out in Sharif Medical and Dental College, Lahore, on 300 patients who underwent coronary angiography during 2018-2019.
Methods: Patients were categorized as right (Rt D), left (Lt D) and co-dominant (Co D) based on the dominance pattern reported on coronary angiograms.
Results: From a total of 300 patients, 258 (86%) were male and 42 (14%) were female with a mean age of 55.59 ± 9.18 years. The majority of the patients had a right dominant coronary artery system 236 (78.7%) whereas left and co-dominance were 44 (14.7%) and 20 (6.7%) respectively. When assessed through the Post Hoc Tukey test the Gensini scoring in the left dominant patients was observed to be significantly higher 83.64 ± 15.282 as compared to the right and co-dominant which were 72.73 ± 24.998 and 73.40 ± 26.589 respectively.
Conclusion: The right coronary artery dominant pattern is more prevalent in our population as compared to left and co dominancy with age and gender have no association. However, the frequency of coronary artery stenosis is much higher in the left dominant pattern as observed through the Gensini scoring system.
