To the Editor, Coronary computed tomography angiography (CCTA) is one of the main imaging modalities used to discard coronary artery disease in patients with stable symptoms; thanks to its excellent negative predictive value, it can characterize atheromatous plaques and the degree of stenosis they cause.1 In some imaging facilities, the CCTA is used after measuring the coronary calcium score often through the Agatston score that does not require initially the injection of contrast. Studies suggest that patients with stable symptoms and lack of coronary calcium (CCS = 0 or Agatston = 0) don’t usually have significant coronary stenoses but a have better prognosis. This is indicative that a CCTA with the corresponding injection of contrast would not provide relevant information in most of the cases.2-4 Therefore, our objectives were to describe the prevalence and characteristic of patients with CCS = 0; also, to assess the findings obtained in the subsequent contrast study and invasive coronary angiography if any; finally, we studied the events occurring at the long-term follow-up in this group of patients. Therefore, we conducted an observational cohort study that included all procedures (CCS and subsequent CCTA) performed in a tertiary center between 2008 and 2016. The authors declare that they acted in accordance with the Declaration of Helsinki. Written informed consent was obtained from all patients. All patients were referred with chest pain and a past medical history of ischemic heart disease. The Philips CT Brillance 64-multislice detector computed tomography scanner and Heartbeat-CS software (Philips Medical Systems, United States) were used. The CCS was assessed using the Agatston score. Stenoses that were > 70% quantitatively were considered significant coronary lesions. |
