Features of anthropometric indicators and dimensions of the coronary sinus and relationships between these indicators in patients without coronary artery pathology

Abstract

Recently, in Ukraine, there has been a significant increase in the possibilities of invasive treatment of cardiovascular pathologies, the number of open-heart cardiosurgical operations and endovascular interventions is increasing. Each of these interventions requires endovascular catheterization of the coronary venous sinus of the heart, the variety of anatomical features of which requires a detailed study of the anatomy of the venous system of the heart. The purpose of the work is to establish the features of the coronary sinus dimensions and anthropometric indicators in men and women without coronary artery pathology, as well as the relationships between these indicators. Weight, body length, body mass index, anterior-posterior size of the chest, as well as the dimensions of the coronary sinus were determined (the length of the coronary sinus from the mouth to the oblique atrial vein, the transverse size of the coronary sinus in the area of the mouth in the sagittal and axial planes, the transverse size of the coronary sinus in the middle third in the sagittal and axial plane, the transverse dimension of the coronary sinus at the level of the oblique vein of the atrium in the sagittal and axial plane) in 15 men and 9 women aged 44 to 60 years (average age according to the age classification of the World Health Organization) without pathology of the coronary arteries, who underwent CT coronary angiography at the “Amosov National Institute of Cardiovascular Surgery NAMS of Ukraine”. Statistical processing of the obtained results was carried out in the license package “Statistica 6.0” using non-parametric estimation methods. As a result of the conducted research, the limits of the percentile range of anthropometric indicators and the size of the coronary sinus in men and women without coronary artery pathology were established. When analyzing the value of these indicators between men and women, only significantly higher values of body mass and length were established in men. Therefore, when analyzing the relationship between the dimensions of the coronary sinus and the anthropometric parameters of the body, the distribution of indicators by sex was not carried out. When analyzing the correlations between age, sex, weight, body length, body mass index, signs of body mass index (indicates underweight, equivalent to normal body weight, indicates the presence of excess weight, or is a sign of obesity) and the anterior-posterior size of the chest with almost all dimensions of the coronary sinus, multiple reliable direct strong (r=0.64 and r=0.67) and medium strength (r=0.44 and r=0.47), as well as unreliable medium strength direct correlations with the anterior-posterior size of the chest were established (r=0.40 in both cases). In addition, multiple nonreliable average strength direct correlations of more than half of coronary sinus dimensions were established with body weight (r= from 0.32 to 0.35). When analyzing the correlations between the sizes of the coronary sinus, multiple reliable direct strong (r= from 0.60 to 0.65) and medium strength (r= from 0.41 to 0.59), as well as unreliable medium strength direct (r= from 0.30 to 0.40) correlations were established with half the size of these indicators.
