The ROMICAT (Rule Out Myocardial Infarction using Computer Assisted Tomography) Trial is used for Coronary Computed Tomography Angiography for Early Triage of Patients With Acute Chest Pain.

Objectives
This study was intended to decide the value of coronary registered tomography angiography (CTA) in patients with intense mid-section torment.

Background
Triage of mid-section torment patients in the crisis division stays testing.

Techniques
It utilized an observational companion study as a part of mid-section torment patients with typical introductory troponin and nonischemic electrocardiogram. A 64-cut coronary CTA was performed before admission to distinguish coronary plaque and stenosis (>50% luminal narrowing). Results were not revealed. End focuses were intense coronary disorder (ACS) amid list hospitalization and major antagonistic heart occasions amid 6-month development.

Results
Among 368 patients (mean age 53 ± 12 years, 61% men), 31 had ACS (8%). By coronary CTA, half of these patients were free of coronary corridor infection (CAD), 31% had nonobstructive illness, and 19% had uncertain or positive processed tomography for noteworthy stenosis. Affectability and negative prescient quality for ACS were 100% (n = 183 of 368; 95% certainty interim [CI]: 98% to 100%) and 100% (95% CI: 89% to 100%), individually, with the nonattendance of CAD and 77% (95% CI: 59% to 90%) and 98% (n = 300 of 368, 95% CI: 95% to 99%), separately, with huge stenosis by coronary CTA. Specificity of nearness of plaque and stenosis for ACS were 54% (95% CI: 49% to 60%) and 87% (95% CI: 83% to 90%), individually. Just 1 ACS happened without calcified plaque. Both the degree of coronary plaque and nearness of stenosis anticipated ACS freely and incrementally to Thrombolysis In Myocardial Infarction hazard score (zone under bend: 0.88, 0.82, versus 0.63, separately; all p < 0.0001).

Conclusions
Fifty percent of patients with intense mid-section agony and low to middle of the road probability of ACS were free of CAD by registered tomography and had no ACS. Given the vast number of such patients, early coronary CTA may altogether enhance quiet administration in the crisis division.
