Kang MG, et al. – Investigators assessed the ability of computed tomography coronary angiography (CTCA)-measured coronary artery calcium score (CACS) to predict periprocedural myocardial infarction (PMI) in patients undergoing elective percutaneous coronary intervention (PCI). Participants included 197 patients with stable angina who underwent elective PCI following CTCA. They assessed CACS using CTCA and evaluated PMI clinical risk factors. They found that, for PMI, the CACS cut-off value was > 113 (area under the curve: 0.670; 95% CI: 0.600–0.736; P < 0.001). They also observed a higher prevalence of PMI among patients with CACS > 113 before PCI. Multivariate analysis indicated that CACS > 113 was the main predictor for PMI. Overall, findings suggested that high CTCA-measured CACS affects the PMI occurrence, which is linked to worse cardiovascular outcomes.
