Coronary Artery Dominance In North Indian Population by The Angiographic Method

Abstract

Background: The rise in coronary heart disease in India has led to a rapid transition in health status. In rural areas, prevalence of coronary artery disease was estimated as 3-4% and 8-10 % in urban areas in the age group of above 20 years. This represents 2 fold rise in rural areas and 6 fold rise in urban areas when compare to past 40 years. Coronary circulation was classified as right , left, and co-dominant. It has clinical importance. It is believed that the persons with left coronary artery dominance is associated with poor prognosis with coronary artery disease and acute coronary syndrome. Method: A total of two hundred and fifteen patients who have undergone angiography were included in this study. Results: One hundred and fifty-six (73%) were male and fifty-three (27%) were female. Right coronary artery was dominant in 184, left dominant in 23 (10.70%) and co-dominant in 8 (3.72%) of the patient population. Among a total of 215 patients, 54 (25.12%) were smokers, 67(31.16%) patients had Pre-hypertension, 42 (19.53%) had Pre-diabetes, and 18 (8.37%) had Dyslipidemia. Conclusions: The right coronary dominant pattern in coronary artery circulation is more prevalent in our population than left coronary dominance and co-dominance patterns. This study would be useful to the surgeons, cardiologists and radiologists of this region. [Singh V Natl J Integr Res Med, 2019; 10(4):70-72]
