Background:
In patients presenting with acute coronary syndrome (ACS) current clinical practice guidelines recommend coronary angiography for its study. This study aims to describe the role of coronary tomography (CT) in non-ST-segment elevation acute coronary syndromes (NSTE-ACS).
Results:
Patients over 18 years with a diagnosis of NSTE-ACS who did not meet high-risk criteria and consulted the emergency department of our institution were included. A total of 410 patients were included, in 7% of them, the study was not continued due to an elevated calcium score (>400 AU). 27% had no coronary lesions, 38% had non-obstructive coronary disease (plaques <50%), 27% had plaques over 50%, and 8% were not assessable. Of the total patients, 39% underwent coronary angiography, and 22% required percutaneous angioplasty.
Conclusions:
Performing CT in low and moderate-risk NSTE-ACS patients was feasible, avoiding invasive studies in a significant number of patients and providing extensive anatomical information.
