A STUDY OF CORONARY DOMINANCE IN POPULATION OF JALGAON REGION OF NORTH MAHARASHTRA BY ANGIOGRAPHIC METHOD

Introduction: The incidence of coronary artery disease is increasing now a day’s all over the world. Dominance pattern of the heart has got important clinical significance in different pathologies. So the present work is undertaken to study the dominance of coronary arteries in population of Jalgaon region of North Maharashtra, India. Aim and objectives: Aim of the present study was to determine dominance pattern of coronary arteries in Jalgaon region and to compare it with other studies. Material and Method: The subjects (n=1000) attending cardiology outpatient department (OPD) at Dr. Ulhas Patil Medical College and Hospital, Jalgaon Kh. formed the study group for this study. Invasive coronary angiography was performed by either femoral or radial route using radio-opaque dye and cineangiograms were taken in different views. Using Schlesinger’s criteria, the coronary dominance was determined Results: In 82.4% of the subjects, right dominance was noted. In 13.3% of the subjects, left dominance was noted. Balanced dominance was noted in 4.3% of the subjects studied. Conclusion: Balanced dominance is significantly less in Jalgaon region of northern Maharashtra when compared with results of most other studies. Similarly right dominance is significantly more in this area when compared with results of most other studies. So it can be concluded that every region carries its own proportions of dominance and detailed studies should be conducted for betterment of human being in each region.
