Abstract Background Current ESC guidelines for non-ST-segment elevation myocardial infarction suggest the utilization of echocardiography in patients with inconclusive initial electrocardiography and cardiac enzymes. Besides detection of alternative pathologies associated with chest pain, echocardiography can screen for wall motion abnormalities (WMA) as sign of myocardial necrosis. Purpose We evaluated the ability of the assessment of regional WMA, detected via transthoracic echocardiography, to predict the presence of culprit lesions in patients presenting with acute chest pain to the emergency department. Methods In this prospective single-centre observational cohort study, we included consecutive patients presenting to the emergency department of our University Hospital with acute chest pain, suggestive of an acute coronary syndrome, between December 2018 and August 2020. Patients with ST-elevation myocardial infarction, hemodynamic instability, or known coronary artery disease were excluded. As part of initial workup, patients received bedside echocardiography for the assessment of regional WMA by a dedicated study physician, blinded to all patients' characteristics. The primary endpoint was defined as the presence of culprit lesions as detected in subsequent invasive coronary angiography, requiring coronary revascularization therapy. Logistic regression analysis was performed in different models adjusted for traditional cardiovascular risk factors, cardiac biomarkers as well as established risk scores. Area under the receiver operating characteristics curve (AUC) was calculated to assess a potential improvement in the prediction of culprit lesions. Results Overall, 657 patients (age 58.06±18.04 years, 53% male) were included in our study. WMA were detected in 76 patients (11.6%). Patients with WMA were older (66.92±13.85 vs. 56.90±18.21 years, p<0.001), had significantly higher Troponin-levels (18.5 [6.0; 91.5] vs. 6.0 [6.0; 15.0], p<0.001) and higher blood pressure (139.0±19.29 vs. 135.1±19.21, p=0.04). WMA were significantly more frequent in patients reaching the primary endpoint (26.2% vs. 7.6%, p<0.001). In multivariable regression analysis, the presence of WMA was associated with 3-fold increased odds of the presence of culprit lesions (3.41 [1.99–5.86], p<0.001). Adding WMA to a multivariable model containing the TIMI risk score, cardiac biomarkers and traditional risk factors significantly improved the AUC for prediction of obstructive coronary artery disease (0.777 to 0.804, p=0.009). Conclusion WMA strongly and independently predict the presence of culprit lesions in patients presenting with acute chest pain to the emergency department. Our results suggest that routine bedside echocardiography for assessment of WMA in emergency department may improve diagnostic algorithms in suspected acute coronary syndrome.

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.

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.

Chest pain is one of the most common presentation to emergency department (ED). The misdiagnosis or over-diagnosis of patients with acute chest pain can be associated with serious clinical events or is time-consuming and this places a heavy burden on overcrowded and resource constraint ED. To help overcome this issue various scores are formed to rule out acute coronary syndrome (ACS) in these patients. Those who do not meet the criteria of high risk ACS like raised cardiac biomarkers, ECG changes, etc are labeled as low risk ACS. These patients form the majority of patients. A multitude of risk score have been formulated to predict the outcome and risk stratify patients with chest pain. Our objective was to evaluate the utility of these score in Indian setting in low risk ACS patients. We studied the various risk prediction score of 100 patients presenting to the ED of tertiary care teaching institute in an urban industrial area with low risk ACS. The scores that were calculated included HEART, TIMI, ADAPT, GRACE, NACPR and EDACS. Of all the scores only the HEART score correlated well with identifying those who required further testing. Taking a score of less than 3 as a marker of low risk ACS we get a sensitivity of 95.83% (95CI - 89.67% to 98.85%) and specificity of 100%. The PPV is 100% and accuracy of 96%. All other scores were either not specific enough or had limited utility. Keywords: Low risk ACS, ACS, HEART, TIMI, ADAPT, GRACE, NACPR, EDACS

Grace Score

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.

Grace Score

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.
