Abstract Objectives We aimed to assess the value of Global Registry of Acute Coronary Events (GRACE) and Thrombolysis in Myocardial Infarction (TIMI) risk scores (RSs) for predicting coronary artery disease (CAD) severity and prognosis in patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS). Background Patients with NSTE-ACS are at varying risks of death and recurrent cardiac events, early risk stratification plays a central role, different scores are now available based on initial clinical history, ECG, and laboratory tests that enable early risk stratification on admission. Methods A prospective study was conducted including 100 patients (age, 45–68 years) with NSTE-ACS who were admitted at our hospital from January 2018 to January 2019. The two RSs (TIMI& GRACE) were calculated from the initial clinical history, electrocardiogram, and laboratory values collected and recorded on admission. All patients were subjected to conventional coronary angiography during admission, Patients were divided into two groups: 1) patients with syntax score ≤32 (test group, 80 patients) and 2) patients with syntax score >32 (comparative group, 20 patients). Median follow-up duration was 6 (4–9) days. Results Regarding correlation between coronary angiographic severity based on syntax score and the clinical profile based on the two RSs (TIMI&GRACE) in NSTE-ACS patients, statistically significant correlation were found between GRACE score and syntax score (r=0.789; P=0.001) with GRACE score accuracy: 94% and negative predictive value (NPV): 98.7%, whereas no statistically significant correlation were found between TIMI score and syntax score (r=0.087; P=0.388) with TIMI score accuracy: 32% and NPV: 73.1%. Conclusions In conclusion the GRACE score provides a quick and reliable prediction of CAD severity in NSTE-ACS patients, It allows accurate risk estimation, categorizes patients and consequently can help in making accurate therapeutic decisions either with the use of invasive strategies in high risk selected patients or the use of conservative strategies in low risk patients in presence of limited resources.

Non-ST-segment elevation acute coronary syndrome (NSTE-ACS) is the leading cause of morbidity and mortality from cardiovascular disease worldwide. Several recent studies have shown the relationship between the triglyceride-glucose (TyG) index and vascular disease; however, the role of the TyG index in NSTE-ACS has not been extensively assessed. Thus, we aimed to investigate the association of the TyG index with cardiovascular risk factors and outcomes in NSTE-ACS. Overall, 438 patients with NSTE-ACS were enrolled to examine the association of the TyG index with the SYNTAX score and major adverse cardiovascular events (MACEs). The TyG index was calculated as ln fasting triglyceride mg/dL×fasting glucose mg/dL/2. The severity of coronary lesions was quantified by the SYNTAX score. MACEs included cardiac death, nonfatal myocardial infarction, target vessel revascularization, congestive heart failure, and nonfatal stroke. All the patients underwent a 12-month follow-up for MACEs after admission. Multivariate regression analysis identified metabolic risk factors as independent parameters correlated with the TyG index. The prevalence of glucose metabolism disorder, metabolic syndrome, and MACEs increased with increasing TyG index. The TyG index showed a strong diagnostic performance for cardiovascular risk factors and was independently associated with the SYNTAX score (OR 6.055, 95% CI 2.915–12.579, P<0.001). The risk of MACEs (12.8% and 22.8% for the low TyG index and high TyG index groups, respectively; adjusted HR=1.791, 95% CI 1.045–3.068, P=0.034) significantly increased in the high TyG index group as compared with the low TyG index group. The multivariate Cox regression analysis further revealed that the TyG index was an independent predictor of MACEs (HR 1.878, 95% CI 1.130–3.121, P=0.015). In conclusion, the TyG index might be an independent predictor of coronary artery disease severity and cardiovascular outcomes in NSTE-ACS.

The patients presenting acute coronary syndrome without ST segment elevation can have a short and long-term risk of death or recurrent ischemic events. Therefore, the evaluation of risk is an essential step in the management of such patients. We report two cases – a 86-year-old male, and a 46-year-old one – with acute coronary syndrome with non-ST-segment elevation, showing the importance of risk assessment to determine management strategy. Two risk profile scores were used: TIMI score and GRACE score. Routine use of validated risk score may facilitate more appropriate tailoring of intensive therapies, but the clinical reasoning of the physician is essential to take right decisions.

Genome-wide association studies have shown that a disintegrin and metalloproteinase with thrombospondin motifs 9 (ADAMTS-9) is associated with the development of atherosclerosis. We assessed the level of ADAMTS-9 in patients with coronary artery disease (CAD) and its severity and prognosis. We selected 666 participants who underwent coronary angiography in our hospital and met the inclusion and exclusion criteria; participants included non-CAD patients, patients with stable angina pectoris (SAP), unstable angina, non-ST-segment elevation myocardial infarction, or ST-segment elevation myocardial infarction. The serum level of ADAMTS-9 was higher in patients with CAD than in non-CAD patients (37.53 ± 8.55 ng/mL vs 12.04 ± 7.02 ng/mL, P < .001) and was an independent predictor for CAD (odds ratio = 1.871, 95% CI: 1.533-2.283, P < .001). Subgroup analysis showed that compared with the SAP group, the acute coronary syndrome groups had higher serum levels of ADAMTS-9. In addition, the level of ADAMTS-9 was related to the SYNTAX score (r = 0.523, P < .001). Patients with acute myocardial infarction (AMI) with elevated levels of ADAMTS-9 had a higher risk of major adverse cardiovascular events (MACE) within 12 months than those with lower levels (log-rank = 4.490, P = .034). Plasma ADAMTS-9 levels may be useful for the diagnosis of CAD and as predictors of MACE in AMI patients.

SummaryIt is well known that the severity of coronary heart disease is associated with a poor prognosis. 70% of patients with NSTEMI have multivascular disease, the percentage being 40% for STEMI patients. Knowing the grade severity of the coronary artery disease has importance for the therapeutic management of the case and to establish the prognosis. However, until now, we have no possibilities to identify these patients before performing the coronarography.The objective of this study was to establish a correlation between cardiovascular risk factors, ECG changes, echocardiographic changes, GRACE score and the severity of coronary artery disease invasively detected by coronarography, in patients with myocardial infarction without ST-segment elevation.Material and methods. We performed a study on 125 patients diagnosed with NSTEMI, who performed coronarography. For each patient we noted age, sex, history of high blood pressure, dyslipidemia, chronic kidney disease, smoking habit, HS troponin T levels, LDL cholesterol, triglycerides, C-reactive protein, creatinine clearance, ejection fraction of left ventricle, number of lesions discovered on angiography, GRACE and SYNTAX score.Results. Of the 125 patients included, 86 (68.8%) were men, with a mean age of 63.66 ± 11.54. The average of the laboratory tests and the parameters studied: creatinine Cl 83.80 ± 33.862 ml / min, FEVS 46.37 ± 7.394%, troponin HS 3533.625 ± 7460.873 pg / ml, CRP 2.811 ± 5.262 mg / dl, LDL 113.618 ± 50.13 mg / dl, triglyceride ± 100.58mg / dl. The mean Syntax score in the studied group was 17, 58 ± 13.65, Grace score 118.80 ± 26.980, and the number of coronary lesions 2.19 ± 1.162 The number of coronary lesions and the SYNTAX score were significantly correlated statistics with age, Grace score, presence of diabetes and chronic kidney disease. With regard to laboratory tests, creatinine clearance proved to be the most important predictor for both the number of vessels affected (r =-0.322, p=0.000) and for the Syntax score (r = -0.323,p=0.000), the latter being influenced also by the level of triglycerides (r = -0.177, p = 0.048) and that of the high sensitive troponin (r = 0.322, p = 0.015).Conclusions. Independent predictors of multivascular disease in patients with NSTEMI are : age, diabetes, chronic kidney disease, creatinine clearance and Grace score. The severity of the coronary heart disease assessed by the Syntax score, is also correlated with age, history of diabetes and chronic kidney disease, creatinine clearance, Grace score, but also with the value of tiglycerides and high-sensitive T troponin.

Background: Few studies have characterized electrocardiography (ECG) patterns correlated with left ventricular (LV) systolic dysfunction in patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS).Objectives: This study aims to develop ECG pattern-derived scores to predict LV systolic dysfunction in NSTE-ACS patients.Methods: A total of 466 patients with NSTE-ACS were retrospectively enrolled. LV ejection fraction (LVEF) was assessed by echocardiography within 72 h after the first triage ECG acquisition; there was no coronary intervention in between. ECG score was developed to predict LVEF &lt; 40%. Performance of LVEF, the Global Registry of Acute Coronary Events (GRACE), Thrombolysis in Myocardial Infarction (TIMI) and ECG scores to predict 24-month all-cause mortality were analyzed. Subgroups with varying LVEF, GRACE and TIMI scores were stratified by ECG score to identify patients at high risk of mortality.Results: LVEF &lt; 40% was present in 20% of patients. We developed the PQRST score by multivariate logistic regression, including poor R wave progression, QRS duration &gt; 110 ms, heart rate &gt; 100 beats per min, and ST-segment depression ≥ 1 mm in ≥ 2 contiguous leads, ranging from 0 to 6.5. The score had an area under the curve (AUC) of 0.824 in the derivation cohort and 0.899 in the validation cohort for discriminating LVEF &lt; 40%. A PQRST score ≥ 3 could stratify high-risk patients with LVEF ≥ 40%, GRACE score &gt; 140, or TIMI score ≥ 3 regarding 24-month all-cause mortality.Conclusions: The PQRST score could predict LVEF &lt; 40% in NSTE-ACS patients and identify patients at high risk of mortality in the subgroups of patients with LVEF ≥ 40%, GRACE score &gt; 140 or TIMI score ≥ 3.

The GRACE score constitutes a useful tool for risk stratification in patients with acute coronary syndrome (ACS), while the SYNTAX score determines the complexity of coronary artery disease (CAD). This study sought to correlate these scores and assess the accuracy of the GRACE score in predicting the extent of CAD. A total of 539 patients with ACS undergoing coronary angiography were included in this analysis. The patients were classified into those with a SYNTAX score < 33 and a SYNTAX score ≥ 33. Spearman’s correlation and receiver operator characteristic analysis were conducted to investigate the role of the GRACE score as a predictor of the SYNTAX score. There was a significantly positive correlation between the SYNTAX and the GRACE scores (r = 0.32, p < 0.001). The GRACE score predicted severe CAD (SYNTAX ≥ 33) moderately well (the area under the curve was 0.595 (0.522–0.667)). A GRACE score of 126 was documented as the optimal cut-off for the prediction of a SYNTAX score ≥ 33 (sensitivity = 53.5% and specificity = 66%). Therefore, our study reports a significantly positive correlation between the GRACE and the SYNTAX score in patients with ACS. Notably, NSTEMI patients with a high-risk coronary anatomy have higher calculated GRACE scores. A multidisciplinary approach by a heart team could possibly alter the therapeutic approach and management in patients presenting with ACS and a high calculated GRACE score.

Background: The superiority of the GRACE and TIMI risk scores in predicting the angiographic severity of coronary artery disease in patients with non ST-elevation myocardial infarction (NSTEMI) has not yet been established. This study was done to compare the GRACE and TIMI risk scores in predicting the angiographic severity of coronary artery disease in this group of patients.Method: The cross sectional study done in the Department of Cardiology, NICVD, Dhaka. The patients admitted with NSTEMI were evaluated to calculate the GRACE and TIMI risk score from April, 2015 to April, 2016.Coronary angiogram was done during index hospitalization and the severity of the coronary artery disease was assessed by vessel score and Gensini score.Results: Of 115 patients assessed, a positive correlation of the vessel score and Gensini score was observed with both the GRACE and TIMI risk scores (p=<0.001) and the GRACE score (r=0.59) correlated better than the TIMI score (r=0.52). The GRACE score presented area under the Receiver Operating Characteristic (ROC) curve of 0.844(95% CI = 0.774 – 0.914) significantly superior to the area under the ROC curve of 0.752(95% CI =0.658– 0.846) of the TIMI score for the difference between the two scores.Conclusion: Both the GRACE and TIMI scores had good predictive value in predicting the severity of coronary artery disease in the patients with NSTEMI but when both the scores were compared, the GRACE score was found to be superior and correlated better with the severity of coronary artery disease.Cardiovasc. j. 2017; 10(1): 45-51

Background: Acute coronary syndrome (ACS) from non-ST-segment elevation myocardial infarction (NSTEMI) and Takotsubo (TK) cardiomyopathy present with similar initial clinical features and can result in left ventricular (LV) dysfunction and acute heart failure. Methods: This study was a retrospective case-control study that identified patients aged 18 years and older who presented with ACS and underwent cardiac catheterization. Results: There were a total of 321 patients in the TK group and 1031 patients in the NSTEMI group. There was significantly worse LV dysfunction in the TK group with average ejection fraction (EF) of 44.35% (±15.11%) versus NSTEMI with an average EF of 47.36% (±13.5%) ( P < .001). The presence of TK yielded of an odds ratio (OR) of 2.373 (95% confidence interval [CI]: 1.165-3.618) and presence of peripheral artery disease (PAD) yielded an OR of 2.053 (95% CI: 1.165-3.618). Conclusions: The presence of TK cardiomyopathy and PAD were independent predictors of patients who had LVEF of <35% and elevated B-type natriuretic peptide levels.
