Abstract Background The Global Registry of Acute Coronary Events (GRACE) score is recommended for stratifying chest pain. However, there are six formulas used to calculate the GRACE score for different outcomes of acute coronary syndrome (ACS), including death (Dth) or composite of death and myocardial infarction (MI), during in hospital (IH), in 6 months after discharge (OH6m) or from admission to 6 months later (IH6m). The more appropriate one for stratification of undifferentiated chest pain remains unclear. We aimed to provide firstly comprehensive evaluation and comparison of six GRACE models to predict 30-day major adverse cardiac events (MACE) in acute chest pain at the emergency department (ED). Methods Patients with acute chest pain were consecutively recruited from August 24, 2015 to September 30, 2017 in EDs of two public hospitals in China. The primary outcome was MACE within 30 days, including death, acute myocardial infarction (MI), emergency revascularization, cardiac arrest and cardiogenic shock. GRACE scores were calculated retrospectively using the prospectively obtained data. Correlation, calibration, discrimination and reclassification of six GRACE models were evaluated. Results A total of 2886 patients were analyzed, with 590 (20.4%) patients getting outcomes. The GRACE (IH6mDthMI), GRACE (IHDthMI), GRACE (IHDth), GRACE (IH6mDth), GRACE (OH6mDth) and GRACE (OH6mDthMI) showed positive linear correlation with actual MACE rates (r≥0.568, p<0.001), first two of which exerted very strong relationships (r>0.9). All these models had good calibration (Hosmer-Lemeshow goodness-of-fit test, p≥0.073) except GRACE (IHDthMI) (p<0.001). The corresponding c-statistics were 0.82(0.81,0.83), 0.83(0.81,0.84), 0.75(0.73,0.76), 0.73(0.72,0.75), 0.72(0.70,0.73) and 0.70(0.68,0.71). Improvement in AUC, NRI and IDI (p<0.001) represented that GRACE (IH6mDthMI) and GRACE (IHDthMI) were superior to other four models in discrimination and reclassification. Conclusions The GRACE (IH6mDthMI) and GRACE (IHDthMI) outperformed other GRACE models in discriminating high or low-risk of 30-day MACE in patients with chest pain. The reasonable application of appropriate GRACE models should be recommended on stratification of undifferentiated chest pain presenting to the ED.

Abstract Background: The Global Registry of Acute Coronary Events (GRACE) score is recommended for stratifying chest pain. However, there are six formulas used to calculate the GRACE score for different outcomes of acute coronary syndrome (ACS), including death (Dth) or composite of death and myocardial infarction (MI), while in hospital (IH), within 6 months after discharge (OH6m) or from admission to 6 months later (IH6m). We aimed to perform the first comprehensive evaluation and comparison of six GRACE models to predict 30-day major adverse cardiac events (MACEs) in patients with acute chest pain in the emergency department (ED). Methods: Patients with acute chest pain were consecutively recruited from August 24, 2015 to September 30, 2017 from the EDs of two public hospitals in China. The 30-day MACEs included death, acute myocardial infarction (AMI), emergency revascularization, cardiac arrest and cardiogenic shock. The correlation, calibration, discrimination, reclassification and diagnostic accuracy at certain cutoff values of six GRACE models were evaluated. Comparisons with the History, ECG, Age, Risk Factors, and Troponin (HEART) and Thrombolysis in Myocardial Infarction (TIMI) scores were conducted. Results: A total of 2886 patients were analyzed, with 590 (20.4%) patients experiencing outcomes. The GRACE(IHDthMI), GRACE(IH6mDthMI), GRACE(IHDth), GRACE(IH6mDth), GRACE(OH6mDth) and GRACE(OH6mDthMI) showed positive linear correlations with the actual MACE rates (r≥0.568, p<0.001). All these models had good calibration (Hosmer-Lemeshow test, p≥0.073) except GRACE(IHDthMI) (p<0.001). The corresponding C-statistics were 0.83(0.81,0.84), 0.82(0.81,0.83), 0.75(0.73,0.76), 0.73(0.72,0.75), 0.72(0.70,0.73) and 0.70(0.68,0.71), respectively, first two of which were comparable to HEART (0.82, 0.80-0.83) and superior to TIMI (0.71, 0.69-0.73). With a sensitivity ≥95%, GRACE(IHDthMI) ≤81 and GRACE(IH6mDthMI) ≤79 identified 868(30%) and 821(28%) patients as low risk, respectively, which were significantly better than other GRACEs and HEART ≤3(22%). With a specificity ≥95%, GRACE(IHDthMI) >186 and GRACE(IH6mDthMI) >161 could recognize 12% and 11% patients as high risk, which were greater than other GRACEs, HEART ≥8(9%) and TIMI ≥5(8%). Conclusions: In this Chinese setting, certain strengths of GRACE models beyond HEART and TIMI scores were still noteworthy for stratifying chest pain patients. The validation and reasonable application of appropriate GRACE models in the evaluation of undifferentiated chest pain should be recommended.

Background: Coronary computed tomography (CT) may improve the early triage of patients with acute chest pain in the emergency department (ED). The aim of this study was to compare the presence and extent of coronary atherosclerotic plaque as detected by coronary CT in patients with and without acute coronary syndromes (ACS). Methods: The study was designed as a prospective, observational cohort study in patients with acute chest pain but negative cardiac biomarkers and no diagnostic ECG changes, admitted to rule out myocardial ischemia. All patients underwent coronary CT prior to hospital admission. The presence of coronary plaque was treated as a dichotomous outcome, and the extent of CAD was defined as number of (1) coronary segments with plaque, or (2) major coronary arteries with plaque detected by MDCT as assessed by two independent observers. The clinical outcome (ACS) was adjudicated by a review committee using established AHA criteria; subjects with history of CAD (stent placement, bypass) were excluded. Results : Among 368 patients with acute chest pain (mean age 53±12 years, 61% male) 31 patients were determined to have ACS (8%). None of the 183 subjects without plaque (50%) had an ACS. Among the remaining 185 subjects (mean age 58.0±11.5 years, 68% male) in whom coronary plaque was detected, patients with ACS had a significantly more plaque (7.2±3.7 vs. 4.2±3.4, p<0.0001 segments) as compared to subjects without ACS. Similar results were seen for calcified plaque and non-calcified plaque (6.5±3.7 vs. 3.6±3.5 segments, p<0.0001; and 3.6±3.2 vs. 1.8±2.2 segments, p<0.0001, respectively). In addition, the rate of ACS increased with the number of major coronary arteries with plaque (1-vessel: 6.8%, 2-vessels: 10.6%, 3 vessels: 30.8%, and 4-vessels: 25%; p<0.01). In contrast, the ratio of non-calcified to calcified plaque was not different between patients with and without ACS (0.68±0.6 vs. 0.54±0.72, p=0.31). Conclusions: The extent of coronary plaque differs between subjects with and without ACS among patients presenting with acute chest pain. Detailed assessment of the extent and composition of coronary plaque may be helpful to assess risk of ACS among patients with acute chest pain but inconclusive initial ED evaluation.

Introduction: Coronary computed tomography angiography (cCTA) allows efficient triage of low-intermediate risk patients with suspected acute coronary syndrome (ACS); appropriate management of patients with moderate stenosis by cCTA is unknown. We evaluated the yield of downstream testing in moderate stenosis patients in a clinical ED cCTA registry. Methods: All consecutive ED patients with acute chest pain undergoing cCTA as part of routine care between October 2012 and July 2014 were screened. Patients with moderate as their worst stenosis (50-69% stenosis) on cCTA were included. Plaque characteristics, resting left ventricular function (by cCTA), results of any functional downstream non-invasive testing, invasive coronary angiography (ICA) and interventions, and discharge diagnosis were reported. ACS was defined as acute myocardial infarction (MI) or unstable angina pectoris (UAP) and adjudicated by an independent committee. Ischemia was defined as clear, territorial abnormality by myocardial perfusion scintigraphy imaging (MPI) or rest or stress echocardiogram, significant dynamic ST-T shift by exercise treadmill test (ETT) and stenosis >70% on ICA or fractional flow reserve (FFR) <0.75. Results: 586 patients underwent cCTA, with 7.2% (n=42) deemed moderate stenosis. Rate of ACS was 14.2% (n=6) with all adjudicated as UAP. Of these, 83% had stenosis caused by lipid-rich plaque; 33% had wall motion abnormalities on cCTA. The majority (n=28; 66%) underwent downstream non-invasive testing. Overall, n=2 (6%) of the non-invasive tests were positive for ischemia while n=3 (42%) of the invasive tests were diagnosed as positive for ischemia (all revascularized) (Figure 1). Conclusions: Unstable angina but not myocardial infarction is frequent among acute chest pain patients with moderate stenosis by cCTA. cCTA findings of lipid-rich plaque and resting functional abnormalities had a relatively higher yield vs. other non-invasive tests to detect ischemia.

Cardiovascular disease is the leading cause of mortality in developed countries andplaces a massive burden on healthcare services. Thousands of patients visit every yearthe Emergency Department (ED) with acute chest pain and a considerable proportionhas an acute coronary syndrome (ACS). In most cases, the electrocardiogram and thecommonly used biomarkers are not helpful in the early diagnosis of myocardialischemia.ObjectiveTo assess the role of ischemia modified albumin (IMA), a novel cardiac biomarker, inexcluding unstable angina (UA) in patients visiting the ED with acute chest pain. Thepredictive value of serum IMA concentrations were evaluated in comparison toechocardiogram.MethodsWe studied 33 patients (84.8% males, age 59.8±10.8 years) who presented at theAccident and Emergency Department with acute chest pain lasting < 3 h, normal ornon-diagnostic electrocardiogram and normal serum troponin and CK-MB levels.Serum IMA levels were determined and a comprehensive echocardiographic studywas performed. All patients were admitted to our Department of Cardiology and thediagnosis of UA was established with exercise or thallium stress test or with coronaryangiography.ResultsFive patients were eventually diagnosed with UA. The area under the curve for thediagnosis of unstable angina based on serum IMA levels was 0.193 (95% confidenceinterval 0.047-0.339, p < 0.05). Serum IMA levels ≥ 31,95 IU/ml had a sensitivity,specificity, positive and negative predictive value for the diagnosis of UA of 40.0%,28.6%, 9.1% and 72.7%, respectively. The sensitivity, specificity, positive andnegative predictive value of echocardiography for the diagnosis of UA was 60.0%,89.3%, 50.0% and 92.6%, respectively.Conclusion: Assessment of serum IMA levels in patients presenting with suspectedUA has comparable negative predictive value with echocardiography for excludingthe diagnosis of UA. Therefore, this biomarker appears to be useful in the diagnosisand stratification of risk in patients with ACS.
