Background: The presence of cardiovascular complications were reported in small studies of critical care patients admitted with SARS-CoV-2infection There is a dearth of data regarding presence of acute coronary syndromes (ACS) in patients admitted with symptomatic SARS-CoV-2 infection, the cause of the myocardial injury and particularities of management. Objectives: The aim of the study is to describe the presence and type ACS in patients admitted with symptomatic SARS-CoV-2 infection. Secondary outcomes were contributing factors, presenting symptoms and medical management. Methods: A descriptive, retrospective study of patients with a positive COVID-19 test and symptomatic infection admitted from 10 March 2020 to 10 April 2020 in our hospital. Results: There were a total of 127 patients admitted with symptomatic SARS-CoV-2 infection. The most common ACS was Type II Myocardial Infarction (MI). 16 patients were diagnosed with type II MI, 3 patients with Non ST elevation myocardial infarction (NSTEMI) and no patient was diagnosed with unstable angina and ST elevation myocardial infarction (STEMI). The most common cause of Type II MI was hypoxia followed by congestive heart failure and new onset atrial fibrillation. One patient has chest pain as presenting symptom. Except for Aspirin loading and use of beta blocker no other antischemic, statin or ACE/ARB medication was used for management of type II MI. All patients with Type II MI were managed by primary care teams. 3 patients developed NSTEMI and were managed by primary care teams with Cardiology consults. Anti-coagulation was considered for all patients. All patients received Aspirin loading, high intensity statin and beta blockers. Conclusions: Majority of patients with ACS had symptoms related to SARS-CoV-2 infection and chest pain was absent in 95% of cases. The most common ACS was type II MI- myocardial ischemia in context of hypoxia and the treatment was focused in treating the underlying cause rather than initiation of classical guideline directed therapy or invasive management. There were no cases of unstable angina and STEMI, results consistent with previous studies underlying the low incidence of STEMI cases during this pandemic.

Glutamyl Transferase

BACKGROUND Gamma glutamyl transferase (GGT) is a biomarker elevated in various cardiovascular diseases due to oxidation mediated free radical damage. It has been recently used in patients presenting with acute coronary syndromes (ACS) for predicting major adverse cardiovascular events and in hospital adverse outcomes. The application of gamma glutamyl transferase to the traditional set of biomarkers like troponin I and T, creatinine kinase-MB (CKMB) adds to the value that it helps in reclassifying the patients into high and low risk and plan the appropriate treatment strategy. METHODS Patients presenting with acute coronary syndromes were classified into STEMI (ST elevation myocardial infarction), NSTEMI (Non-ST elevation myocardial infarction) and unstable angina based on cardiac biomarkers and electrocardiographic changes. Serum gamma glutamyl transferase of these patients were measured by photo spectrometry and were monitored for 5 days for major adverse cardiovascular events. RESULTS Of the study population (N = 210), 41 % presented with STEMI, 24 % unstable angina, 25 % NSTEMI. The normal range of GGT in our study population was 15 - 70 U/l. values more than 70 U/l was considered raised GGT major adverse cardiac events (MACE) was present in 35 % of the study population. 58 % of the patients with MACE had raised GGT (> 70 U/l) which was statistically significant (P < 0.001). The ROC (receiver operator characteristic curve) for GGT to predict MACE was to the left of the reference line and the area under the curve (AUC) was 0.915. The optimal cut-off for GGT to predict MACE from our study was 50.5 with a sensitivity and specificity of 0.813 and 0.868 respectively. CONCLUSIONS Raised GGT was significantly associated with MACE and in hospital adverse outcomes (ventricular arrythmias, heart failure, recurrent angina). GGT can be used as a prognostic marker in patients presenting with ACS.

Abstract Abstract 3171 Introduction: Changes in plasma volume, the intravascular portion of the extracellular fluid volume, can be estimated by measuring changes in the levels of hemoglobin and hematocrit in the blood. In addition to hemoglobin & hematocrit levels, we are also able to use standard dilution techniques with radiolabeled albumin to accurately measure plasma volume changes. It is not known if plasma volume changes influence outcomes in patients with acute coronary syndromes. The aim of this study was to evaluate the effects of plasma volume changes in patients presenting with the acute coronary syndromes. Methods: Consecutive patients presenting to a single tertiary care center from January 2001 to December 2010 with non ST elevation myocardial infarction (NSTEMI) or ST elevation myocardial infarction (STEMI) were enrolled. Admission hemoglobin (Hbpre) & hematocrit (Hctpre) and discharge hemoglobin (Hbpost) and hematocrit levels (Hctpost) were obtained. Plasma volume changes were measured and a validated formula (ΔPV = ((Hbpre/Hbpost) × (100-Hctpost/100-Hctpre)-1) × 100%) was used to calculate the changes in plasma volumes. A detailed chart review was performed to collect information about baseline variables such as age, gender, hypertension, diabetes, hyperlipidemia, smoking status, and congestive heart failure. The Framingham Risk score was also calculated for each individual. Survival analysis was carried out for plasma volume changes of -20% - 0%, 0 – 20%, and ≥20%. Mortality data was collected from the social security death index for the first 60 days post-discharge. Results: A total of 9770 patients with confirmed NSTEMI or STEMI (mean age 61.8 ± 4.8 years, 48.8% women) were included in the final analysis. Mean pre admission hemoglobin (Hbpre) was 10.2 ± 1.4 g/dl and post admission hemoglobin (Hbpost) was 10.4 ± 1.3 g/dl. Change in plasma volume, ΔPV, was categorized into one of four categories, with 131 (1.3%) ≤20%, 6126 (62.7%) -20% - 0%, 3393 (34.7%) 0 – 20%, and 120 (1.2%) ≥20%. There were 509 deaths within 60 days of discharge. Change in plasma volume was found to be an independent predictor of mortality (HR 5.71; 95% CI 4.75 – 6.86, p = 0.0001) in a Cox proportional hazard model. Most of the deaths occurred during the first thirty days as demonstrated by the Kaplan – Meier's survival curve (Figure 1). Receiver operating curve showed an area under the curve of 0.876 for changes in plasma volume. Conclusion: This study shows that hemoglobin and hematocrit, although simple tests, can provide important prognostic information strongly predictive of short term mortality in patients with acute coronary syndromes. Further studies are required to see if monitoring of plasma volume and correction with pharmacological agents such as diuretics may lead to better outcomes. Disclosures: No relevant conflicts of interest to declare.

Abstract OBJECTIVES The aim of this was to analyse current outcomes in patients referred to coronary artery bypass grafting (CABG) for acute coronary syndromes (ACSs), including ST-elevation or non-ST-elevation ACS (non-ST-segment elevation myocardial infarction) or unstable angina. METHODS Patients (n = 2432) undergoing CABG for ACS between January 2010 and December 2017 were prospectively entered into a surgical myocardial infarction registry in North Rhine-Westphalia, Germany. Key end points were in-hospital all-cause mortality (IHM) and major adverse cardio-cerebral events (MACCE). Predictors for IHM and MACCE were analysed by multivariable logistic regression. RESULTS Patients (78% males) were referred for CABG for unstable angina (25%), non-ST-segment elevation myocardial infarction (50%), and ST-segment elevation myocardial infarction (25%). The mean patient age was 68 ± 11 years, logistic EuroSCORE was 19 ± 18% and three-vessel and left main stem diseases were diagnosed in 81% and 45% of patients, respectively. On-pump CABG with cardiac arrest or beating heart was performed in 92% and 2%, respectively, with only 6% off-pump surgery and 6% multiple arterial revascularization (3.1 ± 1.0 grafts, 93% left internal thoracic artery). Emergency CABG was performed in 23% of patients (42% in ST-segment elevation myocardial infarction; P &lt; 0.001). The total IHM and MACCE rates were 8.1% and 17.5% and were highest in ST-segment elevation myocardial infarction patients with 12.6% and 28.5%, respectively (P &lt; 0.001). Key predictors for IHM and MACCE were female gender, elevated troponin, left ventricular ejection fraction, inotropic support, logistic EuroSCORE, cardiopulmonary bypass and aortic clamp time and the need for emergency CABG. CONCLUSIONS Surgical myocardial revascularization in patients with ACS is still linked to substantial in-hospital mortality. Emergency CABG for patients with ACS was associated with poorer outcomes.
