Abstract
Background: Diameter of coronary artery is an important predictor of outcome after percutaneous coronary interventions and coronary artery bypass graft surgery. There is very limited data available about coronary artery dimensions in Indian population. Our aim is to study the normal dimensions of the coronary artery segments in Indians without coronary artery disease by using quantitative coronary angiography and to study the influence of age, sex and body mass index on coronary artery anatomy and dimensions.
Materials and Methods: 100 patients who have undergone coronary angiography with entirely normal coronary angiogram were included in our study.
Results: This study showed the diameter of vessels in males and females when taken together the leftmain was larger in size followed by proximal LAD, proximal LCX & proximal RCA respectively(4.4+-0.78mm, 3.48+-0.53mm, 3.1 +-0.7mm, 3.0+-1 mm). The length of vessels in males and females when taken together the LAD was larger in size followed by RCA and LCX respectively (11.35+-1.54 cm, 11_+-3 cm, 6.40+- 2.5 cm). 86% people in our study population had type III LAD. Study population mostly had right sided dominance 72%. Left main bifurcates in 92%. Females in our study population had smaller size of coronary vessels of which Size of the LAD proximal diameter is statistically significant. Elderly persons have a change in length and diameter of the coronary vessels of which Reduction in the length of Left main stem is statistically significant. Taller persons have an increase in the size of coronary vessels of which Increase in the length and diameter of proximal LAD is statistically significant. Weight of the individual has no correlation with size of coronary arteries Persons with higher BMI has a statistically significant increase in the proximal diameter of RCA and reduction in the length of proximal LAD.
Conclusions: We found that Females in our study population had smaller size of coronary vessels of which Size of the LAD proximal diameter is statistically significant. Elderly persons have a change in length and diameter of the coronary vessels of which Reduction in the length of Left main stem is statistically significant. Taller persons have an increase in the size of coronary vessels of which Increase in the length and diameter of proximal LAD is statistically significant. Weight of the individual has no correlation with size of coronary arteries Persons with higher BMI has a statistically significnt increase in the proximal diameter of RCA and reduction in the length of proximal LAD.
