The research objective was to evaluate influence on duration of stay, and rate of major unfavorable cardiovascular cases, of cardiac CT angiography aided algorithm to evaluate subjects that come up to emergency departments with low to moderate chest pain.

203 successive patients with ischemic type chest pain/discomfort were registered for the study; patients were passed initially through cardiac CT angiography, with following treatment decided by recommendation to results at cardiac CT angiography.

Except for patients with severe stenoses, which had to be admitted to the hospital, other without apparent plaque were instantly discharged; subjects with mild-moderate stenoses and nonobstructive plaque were discharged after a negative troponin test (for muscle constriction). Discharged patients were pursued through for a year, and so; more to that, duration of stay and safety results amid these subjects were equated with patients with low-moderate risk of chest pain that submitted over to standard care procedures, without cardiac CT angiography, at emergency department. Bonferroni method was utilized for to equate duration of stay amid groups.

Of the results, subjects that passed through cardiac CT angiography showed the following: except for 31 with severe stenoses, and 65 with no signs of plaque, about 107 patients showed up with nonobstructive plaque. After pursuance, no cases were detected of death/mortality, or of severe coronary symptom; re-admittance rate to the hospital, due to chest pain was more through with standard of care; average emergency department duration of stay was higher with standard of care approach, in comparison to that with cardiac CT angiography.

Conclusion: orienting troponin measurement to cardiac CT angiography results is secure, and facilitates early discharge of subjects/patients with low-moderate risk of chest pain, ensuing in lessened duration of stay.
