Abstract: There is no consensus as to whether the Coronary Artery Calcium Score (CACS) results can affect the therapeutic approach that is selected for coronary artery disease. The aim of this study was to follow patients’ management over a period of ten years after application of the CACS. Methods : The research was conducted as a prospective, single-center, long-distance study. In 174 asymptomatic patients (78M; aged 58.9 ± 7.86), a CACS examination using 64-slice computed tomography was performed between 2008 and 2009. The patients were divided into three subgroups according to the CACS results using Agatston Units (AU)—G1: CACS = 0 AU (52 pts); G2: CACS = 1–399 AU (64 pts) and G3: CACS ≥ 400 AU (58 pts). During the ten years of follow-up, the classical cardiovascular risk factors, drugs, diseases, and information about the therapeutic approach that was used (PCI—Percutaneous Coronary Intervention; CABG—Coronary Artery Bypass Graft) were also analyzed. Results : The average time until a percutaneous intervention (PCI) was 825.2 ± 1111.7 and for CABG, it was 529.0 ± 833.6. PCI was performed in 5.8% (G1), 4.7% (G2) and 32.6% (G3) of the cases, respectively; p = 0.0000. CABG was performed in 0% (G1), 1.6% (G2) and 18.9% (G3) of the cases, respectively; 0.0035 Yates. The area under the curve in PCI was 0.783 (95% CI: 0.714–0.841); in CABG, it was 0.825 (95% CI: 0.760–0.878) and the average for both groups was 0.838 (95% CI: 0.774–0.889). Conclusions : The coronary artery calcium score can potentially help to predict the best therapeutic approach for coronary artery disease in a ten-year perspective.
