abstract

  • The prevalence of increased ascending thoracic aortic diameter (AAD) and increased descending thoracic aortic diameter (DAD) diagnosed using multislice cardiac computed tomography was investigated in 624 consecutive patients at an academic cardiology practice in 2006. Increased AAD (>3.7 cm) was present in 71 of 361 men (20%) and in 23 of 263 women (9%) (p <0.001). Increased DAD (>3.0 cm) was present in 26 of 339 men (8%) and in 8 of 258 women (3%) (p <0.02). Increased AAD was present in (1) 7 of 96 patients (7%) aged 23 to 50 years, (2) 22 of 234 patients (9%) aged 51 to 65 years, (3) 53 of 263 patients (20%) aged 66 to 80 years, and (4) 12 of 31 patients (39%) aged 81 to 88 years (p <0.005 comparing groups 3 and 1; p <0.001 comparing groups 4 and 1, groups 4 and 2, and groups 3 and 2; p <0.02 comparing groups 4 and 3). Increased DAD was present in (1) 0 of 96 patients (0%) aged 23 to 50 years, (2) 5 of 227 patients (2%) aged 51 to 65 years, (3) 21 of 244 patients (9%) aged 66 to 80 years, and (4) 8 of 30 patients (27%) aged 81 to 88 years (p <0.005 comparing groups 3 and 1, groups 3 and 2, and groups 4 and 3; p <0.001 comparing groups 4 and 1 and groups 4 and 2). In conclusion, men have a higher prevalence of increased AAD and DAD than women, and increasing age increases the prevalence of increased AAD and DAD.
