Rule Out

Abstract Background NSTEMI may be ruled out in patients presenting with acute chest pain based on low baseline high sensitivity troponin (cTn) at admission. This procedure is limited by a low expected frequency of ruled out non-cardiac chest pain (NCCP) patients. Purpose To investigate if stress-induced biomarkers (glucose or copeptin) combined with cTn can increase the rate of NCCP ruled out without an unacceptable increase in incorrectly ruled out NSTEMI. Method 971 patients with suspected NSTE-ACS were included. Final diagnosis was adjudicated by two independent cardiologists using clinical data including routine cTnT. Additionally, baseline cTnI, cTnI from Singulex Clarity System (cTnI(sgx)), copeptin and glucose were measured. Diagnostic performance to rule out NSTEMI was compared between the ESC rule out algorithms for cTnT and cTnI(Abbott), a local cTnI(sgx) algorithm and different combinations of cTn with copeptin or glucose Results Median age 61 years, 60% male. 13% had NSTEMI, 12% had UAP and 60% NCCP. Distribution of copeptin and glucose concentrations (NSTEMI and NCCP) is shown in figure 1. Copeptin and cTnT produces an algorithm with lower miss rate for NSTEMI, increased rule out rate for NCCP and significantly higher AUC (DeLong test, p value <0.001) compared to the ESC algorithm (Table 1). cTnI(sgx) and copeptin showed higher rule out for NCCP and higher AUC (p value <0.001), however an increased rule out rate for NSTEMIs. Combining cTnI(Abbott) and glucose gave a similar miss rate for NSTEMI as ESC, but increased rule out rate for NCCP and higher AUC (p value <0.001). Conclusion Combining cTnT or cTnI(sgx) with copeptin; or cTnI with glucose, improves diagnostic precision and efficacy of rule out protocols for NSTEMI in patients presenting with acute chest pain.

Abstract Purpose To evaluate the feasibility of triple rule out computed tomography (TRO-CT) in an emergency radiology workflow by comparing the diagnostic performance of cardiovascular and general radiologists in the interpretation of emergency TRO-CT studies in patients with acute and atypical chest pain. Methods Between July 2017 and December 2019, 350 adult patients underwent TRO-CT studies for the assessment of atypical chest pain. Three radiologists with different fields and years of expertise (a cardioradiologist—CR, an emergency senior radiologist—SER, and an emergency junior radiologist—JER) retrospectively and independently reviewed all TRO-CT studies, by trans-axial and multiplanar reconstruction only. Concordance rates were then calculated using as reference blinded results from a different senior cardioradiologist, who previously evaluated studies using all available analysis software. Results Concordance rate was 100% for acute aortic syndrome (AAS) and pulmonary embolism (PE). About coronary stenosis (CS) for non-obstructive (<50%), CS concordance rates were 97.98%, 90.91%, and 97.18%, respectively, for CR, SER, and JER; for obstructive CS (>50%), concordance rates were respectively 88%, 85.7%, and 71.43%. Moreover, it was globally observed a better performance in the evaluation of last half of examinations compared with the first one. Conclusions Our study confirm the feasibility of the TRO-CT even in an Emergency Radiology department that cannot rely on a 24/7 availability of a dedicated skilled cardiovascular radiologist. The “undedicated” radiologists could exclude with good diagnostic accuracy the presence of obstructive stenosis, those with a clinical impact on patient management, without needing time-consuming software and/or reconstructions.

Rule Out

Patients presenting at the emergency department with acute chest pain and suspected to represent an acute coronary syndrome were classically admitted as routine to the cardiology department, resulting in expensive and time-consuming evaluations. However, 2-5% of patients with acute coronary syndromes were discharged home inappropriately, resulting in increased mortality. To address the inability to exclude the diagnosis of acute coronary syndrome, chest pain units were developed, particularly in the United States. These provide an environment where serial electrocardiograms, cardiac biomarkers, and provocative testing can be performed to confirm or rule out an acute coronary syndrome. Eligible candidates include the majority of patients with non-diagnostic electrocardiograms. The results have been impressive; chest pain units have markedly reduced adverse events, while simultaneously increasing the rate of safe discharge by 36%. Despite evidence to suggest that care in chest pain units is more effective for such patients, the percentage of emergency or cardiology departments setting up chest pain units remains low in Europe.

Rule Out

Patients with cocaine-related chest pain with electrocardiographic (ECG) abnormalities are often admitted to rule out acute myocardial infarction (AMI). Cardiac troponin I and T should be superior to measurement of creatine kinase (CK)—MB for detecting cardiac injury in patients with coexisting skeletal muscle injury. We prospectively evaluated 19 consecutive patients with acute chest pain related to cocaine use who were hospitalized to rule out AMI. The admission ECG was abnormal in 16 of 19 patients. Total CK and CK—MB were elevated during the hospital course in 14 and 3 patients, respectively. Cardiac troponin I and cardiac troponin T levels were within normal limits in all patients demonstrating that recent myocardial injury did not occur. Clinically, no patient had an AMI. Cocaine-induced thoracic skeletal muscle injury or transient cocaine-induced coronary vasospasm should be considered as alternative sources of chest pain in these patients.
