Detection of coronary artery calcification (CAC) allows for a refined prediction of cardiovascular risk beyond global risk assessment algorithms. Newer-generation, high-resolution, flat-panel digital detector (FPDD) fluoroscopic systems may provide higher CAC detection rates compared with older fluoroscopic devices.
We compared the CAC detection rates of two fluoroscopic techniques in two different cohorts of asymptomatic individuals, analyzed within a two-decade time interval.
FPDD detected CAC more frequently than the older fluoroscopy device, in the more recent and the older patient cohort of individuals, respectively. After propensity score matching to account for differences in age and risk factor prevalence, the adjusted rates of CAC detection remained higher in favor of FPDD (37.7% vs. 23.7%, p=0.026).
The ability of newer cine-fluoroscopic systems to identify CAC in a larger number of asymptomatic, intermediate-risk individuals may have implications for further risk stratification, management of risk factors and long-term prognosis.
冠状动脉钙化（CAC）的检测可在全球风险评估算法之外，对心血管风险进行更精细的预测。新一代的、高分辨率、平板数字探测器（FPDD）透视系统可能比旧的透视设备提供更高的 CAC 检测率。
我们比较了两种透视技术在两个不同的无症状个体队列中的 CAC 检测率，分析时间跨度为二十年。
FPDD 比旧的透视设备更频繁地检测到 CAC，在最近和较早的个体患者队列中均如此。在考虑年龄和危险因素流行率差异进行倾向评分匹配后，FPDD 仍更有利于 CAC 的检测（37.7%比 23.7%，p=0.026）。
新型电影透视系统在更大数量的无症状、中危个体中识别 CAC 的能力可能对进一步的风险分层、危险因素管理和长期预后有影响。
