Coronary circulation assessment in patients before elected surgical correction of abdominal aortic aneurysm

Objective: to assess coronary circulation in patients before planned surgical correction of abdominal aortic aneurysm. Methods. It is a cohort prospective study, which included a comprehensive examination of 71 patients (68 men and 3 women) aged 51 to 80 years with abdominal aortic aneurysm in combination with atherosclerotic lesions of the coronary arteries. All patients underwent electrocardiography, echocardiography, dobutamine stress test, ultrasound duplex scanning of arterial vessels, selective multiposition coronary angiography and computed tomography. Data processing was performed using Statistica 10.0 and StatPlus software. Results. The majority (59.2%) were patients in the 61–70-year-old age group and men (95.8%). In our group of patients, coronary heart disease was previously diagnosed in 73.2% (n = 52). According to recived data, 58 people (81.7%) had damage to at least one of the coronary arteries. At the same time, among patients with clinically significant coronary artery stenosis (more than 50%, n = 53), damage to 3 or more vessels was most often detected (45.3%). In 19 people. (26.8%) IHD was not diagnosed before the CGF (a group of asymptomatic patients with IHD), while 14 people (73.6%) were diagnosed with coronary artery stenosis, of which 11 people (57.9%) had lumen damage of more than 50%, and 2 people (10.5%) had more than 70%. Moreover, 2-vessel damage was diagnosed with the highest frequency (42.9%). The frequency of coronary artery damage in symptomatic patients with IHD (n = 52) was 84.6% (n = 44), and in asymptomatic patients (n = 19) – 73.6% (n = 14). Conclusion. The revealed high frequency of coronary artery disease in both symptomatic and asymptomatic patients underlines the importance of cardiac risk assessment in the form of routine coronary angiography in patients before elective surgical correction of abdominal aortic aneurysm.
