Comparison of primary coronary computed tomography angiography and invasive coronary angiography in patients aged 80 years and older with intermediate-risk non-ST-segment elevation acute coronary syndrome

Aim . To study the strategy for primary coronary computed tomography angiography (CCTA) in patients 80 years and older with intermediate-risk non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Material and methods. The study included 113 patients 80 years and older with intermediate-risk NSTE-ACS (men 26,5%, mean age 82,8±2,3 years). Patients in group 1 (n=43, men 25,6%, mean age 82,9±2,8 years) underwent coronary computed tomography angiography (CCTA), while patients in group 2 (n=70, men 27,1%, mean age 82,7±2,05 years) underwent invasive coronary angiography (ICA). R e sults . Among 43 patients in the coronary CCTA group, the relationship between age and coronary calcium score values were insignificant (Rs=0,67), while more than 70% of patients had moderate coronary calcium index values, allowing for high-quality CCTA. In the coronary CCTA group, 6 patients required ICA, which resulted in percutaneous coronary intervention in two patients, multivessel disease in one patient, and a related artery diameter
