Abstract Introduction GRACE score is strongly validated to determine the probability of death in acute coronary syndrome (ACS), nevertheless its usefulness in nonagenarians, a population with frequently associated comorbidities, is less stablished. BARTHEL and CHARLSON scores might be useful tools to predict outcomes in this population. Objective The aim of this study was to evaluate the potential applicability of GRACE score and two comorbidity scores (CHARLSON and BARTHEL) to estimate prognosis in nonagenarians with ACS. Material and methods We retrospectively included all consecutive patients equal to or older than 90 years old admitted with non-ST (NSTEMI) or ST segment elevation myocardial infarction (STEMI) in four tertiary care centers between 2005 and 2018. Patients with type 2 myocardial infarction were excluded. We collected patients' baseline characteristics and procedural data. In-hospital and at 1-year follow-up all-cause and cardiovascular mortality were assessed. Risk score accuracy was evaluated by area under the curve ROC (AUC). Results A total of 444 patients (mean age 92.6±2.4 years, 60% females) were analyzed. Approximately half of them (n=241, 54%) with STEMI and the remainder (n=203, 46%) with NSTEMI. Global GRACE-AUC for in-hospital and 1-year all-cause mortality were moderate (0.64; 95% CI: 0.59–0.69 and 0.62; 95% CI: 0.57–0.67, respectively). Only in the NSTEMI group, the GRACE-AUC was better to predict in-hospital mortality, 0.70 (95% CI: 0.63–0.77). Neither CHARLSON nor BARTHEL showed better predictive results than GRACE score (AUC ≤0.60). Conclusion GRACE score has moderate accuracy to estimate mortality in nonagenarian patients with ACS. BARTHEL and CHARLSON scores do not improve the predictive value of GRACE score. An individualized approach is required to make therapeutic decisions in this special population. Figure 1.

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.

ABSTRACT BACKGROUND: Atherosclerotic heart disease is still a leading cause of mortality despite improvements in cardiovascular care. Percutaneous coronary intervention (PCI) is the recommended reperfusion therapy in acute ST-elevation myocardial infarction (STEMI), and the international guideline is to achieve a door-to-balloon (D2B) time within 90 minutes of patient arrival to an emergency department (ED). OBJECTIVES: Describe interventions, data for the study period, challenges in ensuring 24/7 patient access to PCI and quality indicators. DESIGN: Retrospective observational study. SETTING: Tertiary care institution in Riyadh, Saudi Arabia. PATIENTS AND METHODS: We included all acute coronary syndrome patients from 2010-2018 who presented or were transferred to our ED from nearby non-PCI capable hospitals, and for whom a ‘code heart’ was activated. Electronic medical records and the patient care report from the ambulance services were accessed for data collection. MAIN OUTCOME MEASURES: D2B time, readmission and mortality rate. SAMPLE SIZE AND CHARACTERISTICS: 354 patients, mean age (standard deviation) 55.6 (12.6) years, males 84.5% (n=299). RESULTS: STEMI patients constituted 94% (n=334) of the study group; the others had non-STEMI or unstable angina. Hypertension (51%) was the most prevalent risk factor. Coronary artery stenting was the most frequent intervention (77.4%) followed by medical therapy (14.7%). The most common culprit artery was the left anterior descending (52.5%) followed by the right coronary artery (26.0%). A D2B time of within 90 minutes was achieved in over 85% of the patients in four of the years in the 278 patients who underwent PCI. The median D2B time (interquar-tile range) over 2010-2018 was 79 (31) minutes. CONCLUSION: Meeting the international benchmark of D2B time within 90 minutes for STEMI patients is achievable when the main stakeholders collaborate in patient-centric care. Our patient demographics represent regional trends. LIMITATIONS: Patient acceptance to our institution is based upon eligibility criteria. Transfer of ‘code heart’ patients from other institutions was carried out by our ambulance team. The credentials and experience of cardiologists, emergency physicians, and ambulance services are not standardized across the country. Therefore, the results may not be generalizable to other institutions. CONFLICT OF INTEREST: None.

Background: Clinical scores and biomarkers improve risk stratification of patients with acute coronary syndromes. However, little is known about their value in patients referred for coronary angiography. Methods: Consecutive patients admitted at four Swiss university hospitals with a diagnosis of acute coronary syndrome were enrolled into the SPUM-ACS Biomarker Cohort between 2009 and 2012. Patients were followed at 30 days and 1 year with assessment of adjudicated events including all-cause mortality and the composite of all-cause mortality or non-fatal recurrent myocardial infarction. Results: Events and biomarkers were analysed in 1892 patients (52.4% with ST-segment elevation myocardial infarction, 43.3% with non-ST-segment elevation myocardial infarction and 4.3% with unstable angina). Death at 30 days occurred in 35 patients (1.9%) and at 1 year in 80 patients (4.3%). The choice of troponin assay (conventional versus high sensitivity) to calculate the Global Registry of Acute Coronary Events (GRACE) score did not affect risk prediction. The prognostic accuracy of the GRACE score was improved when combined with three individual biomarkers including high sensitivity troponin T (hsTnT), N-terminal-pro B-type natriuretic peptide (NT-proBNP) and high sensitivity C-reactive protein (hsCRP) to yield a 9% increment (C-statistic 0.73–>0.82) for the discrimination of short-term risk for all-cause mortality. In contrast, the novel biomarkers placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and the ratio sFlt-1/PlGF did not improve risk stratification. Conclusions: In patients with acute coronary syndrome referred for coronary angiography, combinations of biomarkers including hsTnT, NT-proBNP and hsCRP with the GRACE score enhanced risk discrimination.

Objectives: Presage for early risk stratification is consequential for long term clinical outcomes in patients with non-ST elevation acute coronary syndrome. Thrombolysis in Myocardial Infarction risk scores (TIMI) and Global Registry of Acute Cardiac Events (GRACE) have been most extensively investigated risk scores till date for risk stratification in patients admitted with Cardiovascular disease. Study Design: Descriptive Case Series. Setting: Department of Cardiology Ayub Teaching Hospital, Abbottabad. Period: 4th August 2016 to 4th April 2017. Material & Methods: 199 patients diagnosed with NSTEMI were included in the study after obtaining an apprised consent. Risk stratification of each patient was done according to GRACE score. Patients were followed up during their hospital stay and their outcome was recorded on a pre-designed pro forma. The outcome was described as either death or discharge. Results: Mean±SD GRACE score was 156.12±20.65. The overall mortality in the study population was 11.6% (n=23). When the outcome variable was stratified according to age, gender, diabetes mellitus, obesity and hypertension, results were found in case of hypertension (p< 0.05), and statistically no significant in the case of other variables. Conclusion: A high risk GRACE score is associated with increased in-hospital mortality in patients with NSTEMI.

Abstract Aims The Global Registry of Acute Coronary Events (GRACE) score was developed to evaluate risk in patients with myocardial infarction. However, its performance in type 2 myocardial infarction is uncertain. Methods and results In two cohorts of consecutive patients with suspected acute coronary syndrome from 10 hospitals in Scotland (n = 48 282) and a tertiary care hospital in Sweden (n = 22 589), we calculated the GRACE 2.0 score to estimate death at 1 year. Discrimination was evaluated by the area under the receiver operating curve (AUC), and compared for those with an adjudicated diagnosis of type 1 and type 2 myocardial infarction using DeLong’s test. Type 1 myocardial infarction was diagnosed in 4981 (10%) and 1080 (5%) patients in Scotland and Sweden, respectively. At 1 year, 720 (15%) and 112 (10%) patients died with an AUC for the GRACE 2.0 score of 0.83 [95% confidence interval (CI) 0.82–0.85] and 0.85 (95% CI 0.81–0.89). Type 2 myocardial infarction occurred in 1121 (2%) and 247 (1%) patients in Scotland and Sweden, respectively, with 258 (23%) and 57 (23%) deaths at 1 year. The AUC was 0.73 (95% CI 0.70–0.77) and 0.73 (95% CI 0.66–0.81) in type 2 myocardial infarction, which was lower than for type 1 myocardial infarction in both cohorts (P &lt; 0.001 and P = 0.008, respectively). Conclusion The GRACE 2.0 score provided good discrimination for all-cause death at 1 year in patients with type 1 myocardial infarction, and moderate discrimination for those with type 2 myocardial infarction.

Abstract Background Various risk scores have been proven to predict outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). However, few of them were validated and compared the difference of the prediction of infection during hospitalization in such patients. Aim We aimed to validate and compare the discriminatory value of different risk scores for predicting infection. Methods Patients who were diagnosed with STEMI treated with PCI were enrolled from January 2010 to May 2018. The six risk scores included the Age, Serum Creatinine (SCr), or Glomerular Filtration Rate, and Ejection Fraction (ACEF or AGEF) score, Canada Acute Coronary Syndrome Risk Score (CACS score), CHADS2 score, Global Registry for Acute Coronary Events (GRACE) score and Mehran score. The primary end point was infection during hospitalization. The secondary endpoint was major adverse clinical events including all cause death, stroke and any bleeding. The prognostic accuracy of the six scores was assessed using the c statistic for discrimination and the Hosmer-Lemeshow test for calibration. Results A total of 2260 eligible patients were enrolled (62.32±12.36 year, 81.3% of males). A significant gradient of risk with respect to infection and in hospital major adverse clinical events (MACE) was observed with increasing all six risk scores. Other than the CHADS2 score (AUC: 0.682; 95% CI, 0.652–0.712), other five risk scores showed the good discrimination for predicting infection, with the GRACE score being the best (AUC: 0.791; 95% CI, 0.765–0.817). In addition, all risk scores showed best calibration for infection, but good calibration for CACS risk score (calibration slope: 0.77, 95% CI: 0.18–1.35) (Figure 1). Furthermore, each score showed a best discrimination for in hospital MACE, with AUCs ranging from 0.761 to 0.786, other than CACS risk score and CHADS2 risk score with AUC of 0.700 and 0.696, respectively. All risk scores showed best calibration for in hospital MACE. Conclusions In patients with STEMI undergoing PCI, these risk scores (ACEF, AGEF, CACS, GRACE and Mehran) showed good discrimination and calibration to predict infection and MACE. The CACS score was recommended for clinical use as its clinical variables were simple and practical. Figure 1 Funding Acknowledgement Type of funding source: Public Institution(s).

St Elevation

Acute coronary syndromes (ACS) include unstable angina pectoris (UAP), non-ST elevation (NSTEMI), and ST elevation acute myocardial infarction (STEMI). Each year, more than 2 million people are hospitalized with ACS in the United States. The initial treatment has evolved over the last few decades from conservative management to early reperfusion therapy. Medical therapy has also significantly changed with the use of newer more potent antiplatelet agents, beta-blockers, angiotensin converting enzyme inhibitors, statins, and anti-anginal drugs, which have resulted in improvement of patient care and survival. There is no role for stress myocardial perfusion imaging (MPI) in the acute presentation; however, rest MPI may be used to identify the culprit lesion and risk stratify patients if injected during chest pain. In stable patients for ACS, submaximal exercise or vasodilator MPI can be performed as early as 48 hours after the event. Several gated MPI-derived variables such as left ventricular (LV) ejection fraction (EF), LV volumes, infarct size, mechanical dyssynchrony, and residual ischemic burden can risk stratify patients and provide prognostic data incremental to validated clinical risk scores such as GRACE (Global Registry of Acute Coronary Syndrome) and TIMI (Thrombolysis in Myocardial Infarction). Patients with depressed LVEF, remodeled LV, and large perfusion defects are at particularly high- risk for subsequent cardiac death or recurrent myocardial infarction. In such setting, MPI plays a pivotal role in the management of patients and guiding therapeutic decisions. The current chapter will review the clinical and MPI predictors of outcomes in patients presenting with ACS according to updated guidelines and a proposed algorithm integrating the role of MPI in guiding therapeutic decisions and management.

Background: Coronary artery disease (CAD) is the single largest cause of death in the developed countries and is one of the leading causes of disease burden in developing countries. The prevalence of dyslipidemia and conventional risk factors profile at the time of admission in patients with Acute Coronary Syndrome (ACS) is not well described in our context. The aim of this study was to investigate the prevalence of dyslipidemia and conventional risk factors profiles of patients with ACS in a tertiary care center of Bangladesh. Methods: This descriptive cross-sectional study included 96 admitted patients of ACS [30 cases of Unstable Angina, 25 cases of Non ST segment Elevation Myocardial Infarction and 41 cases of ST segment Elevation Myocardial Infarction] from the Department of Cardiology, Abdul Malek Ukil Medical College Hospital, Noakhali, Bangladesh from January 2019 to June 2019. Fasting serum lipid profile was obtained within 24 hours of hospitalization and demographic and other cardiovascular risk factors were documented. Results: The mean age of the subjects were 57.7±14.4 years with majority (71.9%) being male. The most frequent reported risk factor was smoking, present in 55.2% of patients, followed by hypertension (47.9%), diabetes (37.5%), dyslipidemia (27.1%) and family history of CAD (15.6%). Based on Body Mass index 50% patients were obese (≥25kg/m2) and 69.8% had central obesity based on waist circumference. The lipid profile analysis revealed that 99% of patients had some type of dyslipidemia, and the most frequent was high level of triglyceride and low levels of high-density lipoprotein cholesterol (68.8% of cases in each). Conclusion: Dyslipidemia is a significant risk factor in patients with ACS and high TG and low HDL-C were more prevalent. Careful attention to its management may help to reduce further events.

Abstract Introduction The TIMI (Thrombolysis in Myocardial Infarction) and GRACE (Global Registry of Acute Coronary Events) risk scores identify high-risk patients with Non-ST elevation acute coronary syndrome (NSTE-ACS) who can benefit from an early invasive strategy. Purpose We aimed to compare both scores predictive accuracy for mortality in a real-world cohort of patients presenting with NSTE-ACS. Methods We retrospectively evaluated 4264 patients admitted to our coronary intensive care unit between 2004 and 2017 with a diagnosis of NSTE-ACS. The TIMI and GRACE scores were calculated for each patient, and all-cause mortality was recorded during hospitalization, at one month and one year. To better characterize global troponin release, we defined Total Troponin (TT) as the sum of initial and discharge troponin. We used the area under the receiver operating characteristic curve (AUC) to compare the predictive value of both scores for mortality during hospitalization, at one month and one year. Results Mean patient age was 67.6±12.4 years and 66.4% were male (n=2833). Mean GRACE score was 124.6±35.8 and mean TIMI score was 2.7±1.6. There was a weak correlation between GRACE and TIMI score (r=0.3, p&lt;0.001). In-hospital mortality was 2.8%: the GRACE score showed higher AUC (0.845, 95% CI 0.805–0.804, p&lt;0.001) compared to TIMI (0.581, 95% CI 0.519–0.643, p=0.009) (Figure 1). Mortality at one month was 5.1%: the GRACE score showed higher AUC (0.842, 95% CI 0.814–0.869, p&lt;0.001) compared to TIMI (0.586, 95% CI 0.541–0.630, p&lt;0.001). Mortality at one year was 11.4%: the GRACE score showed higher AUC (0.811, 95% CI 0.789–0.822, p&lt;0.001) compared to TIMI (0.591, 95% CI 0.560–0.622, p&lt;0.001) (Fig. 1). Analyzing Unstable Angina and Non-ST segment elevation myocardial infarction separately, the GRACE score also showed higher AUC compared to TIMI. Exploratory analyses revealed a combined indicator (GRACE score + TT) which had higher AUC (0.876, 95% CI 0.844–0.907, p&lt;0.001) compared to GRACE score (0.855, 95% CI 0.823–0.887, p&lt;0.001) for one month mortality and for one year mortality (0.818, 95% CI 0.792–0.844, p&lt;0.001 vs. 0.813, 95% CI 0.788–0.839, p&lt;0.001). Conclusion In patients with NSTE-ACS, GRACE risk score is a better predictor of in-hospital, one month and one-year mortality, compared to TIMI risk score. TT, as a measure of ischemia burden, might improve accuracy of GRACE score in predicting short and long-term mortality. Figure 1 Funding Acknowledgement Type of funding source: None

Cangrelor is the first and only intravenous P2Y12-inhibitor and is indicated when (timely) administration of an oral P2Y12 inhibitor is not feasible in patients undergoing percutaneous coronary intervention (PCI). Our study evaluated the first years of cangrelor use in two Dutch tertiary care centers. Cangrelor-treated patients were identified using a data-mining algorithm. The cumulative incidences of all-cause death, myocardial infarction, definite stent thrombosis and major bleeding at 48 h and 30 days were assessed using Kaplan–Meier estimates. Predictors of 30-day mortality were identified using uni- and multivariable Cox regression models. Between March 2015 and April 2021, 146 patients (median age 63.7 years, 75.3% men) were treated with cangrelor. Cangrelor was primarily used in ST-segment elevation myocardial infarction (STEMI) patients (84.2%). Approximately half required cardiopulmonary resuscitation (54.8%) or mechanical ventilation (48.6%). The cumulative incidence of all-cause death was 11.0% and 25.3% at 48 h and 30 days, respectively. Two cases (1.7%) of definite stent thrombosis, both resulting in myocardial infarction, occurred within 30 days, but after 48 h. No other cases of recurrent myocardial infarction transpired within 30 days. Major bleeding occurred in 5.6% and 12.5% of patients within 48 h and 30 days, respectively. Cardiac arrest at presentation was an independent predictor of 30-day mortality (adjusted hazard ratio 5.20, 95%-CI: 2.10–12.9, p < 0.01). Conclusively, cangrelor was used almost exclusively in STEMI patients undergoing PCI. Even though cangrelor was used in high-risk patients, its use was associated with a low rate of stent thrombosis.
