Analysis of gender influence on left main coronary artery dimensions in patient with coronary artery disease single center observational study

Background: The aim of the study is to find out gender influence on the left main coronary artery (LMCA) dimensions in patients with coronary artery disease. Involvement of left main coronary artery in coronary artery disease makes it separate subset of ailment in terms of intervention and medical management point of view. Our objective is to find out the mean length and diameter of left main coronary artery in coronary artery disease patients. Whether gender has any correlation with these dimensions. Retrospective, single centre observational analytical study.Materials and Methods : Study was conducted in Thanjavur Medical College. Department of Cardiology.From the coronary angiogram and case history of 77 coronary heart disease admitted in the department between July and August of 2021. Coronary angiogram was done in Phillips Allura XD Single plane catheterisation lab. Left main coronary artery dimensions were measured by quantitative coronary angiogram in LAO caudal view and in case of foreshortening few cases AP caudal view preferred for measurement. Measurements were done after calibration with diagnostic 5F Tiger Catheter in of the cases. Body surface area was calculated by Du bois formula. Data obtained was analysed by SPSS software.Results: Left main coronary dimensions like mean diameter and mean length of LMCA were analysed against gender. Also influence of age, family history and co- morbid conditions were also analysed.Conclusion: Mean Left main coronary artery diameter is significantly associated influenced by gender with male have higher value than females without indexing to body surface area.
