可能性急性冠状动脉综合征的CT造影

Litt et al. (April 12 issue)1 report a reduction in the length of stay in the hospital by about 7 hours when risk stratification for coronary disease was performed by means of routine coronary computed tomographic angiography (CCTA) in parallel with serial biomarker assessment, as compared with clinically guided strategies initiated after serially negative biomarker levels had been ascertained. However, this logistic advantage of CCTA came at the cost of greater use of diagnostic testing during the index visit (one or more tests in 91% of patients in the CCTA group vs. in 64% of patients who received traditional care). Indirect calculation based on data presented in Table 2 of
