Methods and materials
Calcium Score studies are made at our Institution with a Philips Brilliance 64-slice CT Scanner.
The images were obtained with ECG-gating.
Each slice has a 3mm thickness,
tube voltage of 120 kVs with a radiation dose less than 2 mSv. All studies were interpreted by radiologists and cardiologists with speciality in Cardiovascular imaging.
Clinical and laboratory data necessary for the Framingham risk score calculator and the AHA/ACC ASCVD risk algorithm were obtained from the personal file of each patients with their previous consent.
This data included: age,
gender,
LDL,
HDL and total cholesterol levels,
systolic and dyastolic blood pressure values,
smoking habit,
previous diagnose of systemic arterial hypertension and previous diagnose of diabetes mellitus.
Each one of the already mentioned variables were obtained on the same day that the calcium scoring scans were performed.
The data was stored in an Excel spreadsheet and processed by the SPSS Statistics 25 by IBM® programme for the statistical analysis.
The correlation between Agatston calcium score,
Framingham score and the ACC/AHA ASCVD risk algorithm was performed with the Spearman method.
