Atrial volumes in men and women with mesomorphic body type and excessive body mass

Objective: to determine the indicators of atrial volume in men and women with overweight mesomorphic body type in the first and second periods of adulthood with echocardiography and to identify their correlation with the gender and age of the subject. Material and methods. The analysis of heart ultrasound protocols was carried out in 122 conditionally healthy overweight individuals (body mass index — 29-31), divided into two age groups: group I — 39 men aged 22-35 years and 25 women aged 21-35 years, group II — 26 men aged 36-60 years and 32 women aged 36-55 years. Atrial volumes were measured. Results. The volume of the atria in the first period of adulthood on the right/left in men and women, respectively, is: 46,6±6,4/28,3±2,5 cm; 37,6±5,3/24,6±3,0 cm. The same parameter in the second period of adulthood was: 47,7±5,1/27,8±3,8 cm; 42,5±5,8/23,9±2,0 cm. In all cases, the atria are statistically significantly larger in men (p=0,001). A relationship was established between the volume of the left atrium and the gender of the subject (K/-0.436; p=0,008). During the analysis of the relationship between the atrial volume and age, the following results were obtained: in the group of men —the volume of the right atrium (A=0,032; p=0,846), the volume of the left atrium (A=0,014; p=0,514); in the group of women —the volume of the right atrium (r=0,32; p=0,024), the volume of the left atrium (A=0,088; p=0,539). Conclusion. Mean atrial volume in men in both the first and second periods of adulthood are greater than in women. Gender affects the volume of the left atrium. In men, the left atrium volume is greater than in women. Age does not affect the atrial volumes in men, but it does affect the right atrium volume in women.
