Background/Introduction: Global reports are suggestive of decline in number of patients attending hospital with acute coronary syndromes (ACS) and a reduction in the number of cardiac procedures since the onset of COVID-19 pandemic. Purpose The aim of the study was to compare the trend of presentations and management among ACS patients in a single tertiary cardiac centre in the West midlands of United Kingdom (UK) during the early lock down period of COVID-19 pandemic (Group 2020) in comparison to the same period of 2019 (Group 2019). Methods In this descriptive study patients’ records were extracted retrospectively from the electronic database who presented with ST segment elevation myocardial infarction (STEMI), non- ST segment elevation myocardial infarction (NSTEMI) and Unstable angina (UA), during the 30 day period from mid-March to mid-April of 2020 (Group 2020), and the same period of 2019 (Group 2019). Results In comparison to group 2019, total number of ACS (153 vs 91) including STEMI (70 vs 59), NSTEMI (76 vs 31) and UA (7 vs 1) were lower in group 2020 (Fig 1A). Inter-hospital transfer (IHT) dropped from 2019 to 2020 (55 vs 17). In group 2020, percutaneous coronary angioplasty (PCI) for STEMI was similar to group 2019 (83.05% vs 88.57%) but PCI for NSTEMI were higher (80.65% vs 48.68%). No coronary artery bypass graft (CABG) services were available during the studied period (Fig 1B).  In terms of troponin I (Trop I) levels at the time of admission, 47.25% of all ACS presentations were over 1000ng/L in group 2020 compared to 28.76% in group 2019 (Fig 1C). On assessment of left ventricular ejection fraction (LVEF) at the time of admission, 24% of all ACS were severely impaired (LVEF < 40%) compared to 13.79% in 2019 (Fig 1D). 37 (31 IHT) patients in group 2019 and 16 (11 IHT) patients in group 2020 had no transthoracic echocardiogram data. There was an overall reduction in number of days spent in hospital per ACS patient from 4.78 days in 2019 to 3.70 days in 2020 and a further reduction for STEMI patients from 5.16 days in 2019 to 3.83 days in 2020. 5 ACS patients died in 2020 in comparison to 6 patients in 2019. Conclusion The reduced number of admissions is likely to be a result of nation-wide lock-down and public fear. Proportion of ACS patients with high level of troponin I values and severely impaired LVEF may be explained due to late presentation. It remains necessary to address public fear and to ensure that ACS patients are managed in accordance with ACS management guidelines even in the times of COVID-19 pandemic. Abstract Figure.

Objective.Recent studies suggest that IL-38 is associated with autoimmune diseases. Furthermore, IL-38 is expressed in human atheromatous plaque. However, the plasma levels of IL-38 in patients with ST-segment elevation myocardial infarction (STEMI) have not yet to be investigated.Methods.On admission, at 24 h, at 48 h, and at 7 days, plasma IL-38, C-reactive protein (CRP), cardiac troponin I (cTNI), and N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) levels were measured and IL-38 gene in peripheral blood mononuclear cells (PBMCs) was detected in STEMI patients.Results.The results showed that plasma IL-38 levels and IL-38 gene expression in PBMCs were significantly increased in STEMI patients compared with control group and were time dependent, peaked at 24 h. In addition, plasma IL-38 levels were dramatically reduced in patients with reperfusion treatment compared with control group. Similar results were also demonstrated with CRP, cTNI, and NT-proBNP levels. Furthermore, IL-38 levels were found to be positively correlated with CRP, cTNI, and NT-proBNP and be weakly negatively correlated with left ventricular ejection fraction (LVEF) in STEMI patients.Conclusions.The results indicate that circulating IL-38 is a potentially novel biomarker for patients with STEMI and IL-38 might be a new target for MI study.

We assessed the prognostic role of serum endocan level in patients with ST-segment elevation myocardial infarction (STEMI) and compared the results with a normal coronary angiography group. A total of 133 patients were included in the study (88 patients with STEMI and 45 patients with normal coronary arteries). The SYNTAX score was determined based on the baseline coronary angiogram. Multivariate logistic regression analysis indicated that endocan independently correlated with the presence of STEMI. Moreover, high-sensitivity C-reactive protein (hsCRP), peak troponin I, and left ventricular ejection fraction (LVEF) were found to be independently associated with STEMI. Endocan level correlated significantly with hsCRP and SYNTAX score. We analyzed the discriminatory capability of endocan level for the presence of STEMI using a receiver–operating characteristics curve. A cutoff endocan level of 1.7 (ng/mL) predicted the presence of STEMI with a sensitivity of 76.1% and specificity of 73.6%. In conclusion, a high endocan level on hospital admission is an independent predictor of a worse cardiovascular outcome and a high SYNTAX score in patients with STEMI.

Abstract Background Left ventricular negative remodelling after ST-segment elevation myocardial infarction (STEMI) is considered as the major cause for the poor prognosis. But the predisposing factors and potential mechanisms of left ventricular negative remodelling after STEMI remain not fully understood. The present research mainly assessed the association between the stress hyperglycaemia ratio (SHR) and left ventricular negative remodelling. Methods We recruited 127 first-time, anterior, and acute STEMI patients in the present study. All enrolled patients were divided into 2 subgroups equally according to the median value of SHR level (1.191). Echocardiography was conducted within 24 h after admission and 6 months post-STEMI to measure left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD). Changes in echocardiography parameters (δLVEF, δLVEDD, δLVESD) were calculated as LVEF, LVEDD, and LVESD at 6 months after infarction minus baseline LVEF, LVEDD and LVESD, respectively. Results In the present study, the mean SHR was 1.22 ± 0.25 and there was significant difference in SHR between the 2 subgroups (1.05 (0.95, 1.11) vs 1.39 (1.28, 1.50), p < 0.0001). The global LVEF at 6 months post-STEMI was significantly higher in the low SHR group than the high SHR group (59.37 ± 7.33 vs 54.03 ± 9.64, p  = 0.001). Additionally, the global LVEDD (49.84 ± 5.10 vs 51.81 ± 5.60, p  = 0.040) and LVESD (33.27 ± 5.03 vs 35.38 ± 6.05, p  = 0.035) at 6 months after STEMI were lower in the low SHR group. Most importantly, after adjusting through multivariable linear regression analysis, SHR remained associated with δLVEF (beta = −9.825, 95% CI −15.168 to −4.481, p  < 0.0001), δLVEDD (beta = 4.879, 95% CI 1.725 to 8.069, p  = 0.003), and δLVESD (beta = 5.079, 95% CI 1.421 to 8.738, p  = 0.007). Conclusions In the present research, we demonstrated for the first time that SHR is significantly correlated with left ventricular negative remodelling after STEMI.

Abstract Objective To investigate the correlation between Procollagen I C-Terminal Propeptide (PICP), Procollagen III N-Terminal Propeptide (PIIINP), indices of echocardiography and anamnestic data in patients with ST segment elevation myocardial infarction (STEMI) and preserved myocardial contractility. Materials and methods 60 men and 23 women diagnosed with STEMI were examined. Echocardiographic studies were performed using SONOS 2500 Cardiac – Vascular Ultrasound (Hewlett Packard, USA). Myocardial contractility was considered to be preserved with left ventricular ejection fraction (LVEF) ≥50%. In addition to standard indices of echocardiography, mitral flow propagation velocity (FPV) was evaluated to diagnose diastolic dysfunction. Coronary angiography was performed using INNOVA 3100 Cardiovascular Imaging System (USA). All patients, during the first twelve hours of the disease, underwent percutaneous coronary intervention (PCI) with stenting of the occluded culprit infarct-related artery. On the 1st and 12th days of hospitalization, the concentrations of PICP and PIIINP were determined for all patients by enzyme-linked immunosorbent assay (ELISA) using laboratory BCM Diagnostics kits (USA). All patients at the hospital received standard therapy. Results The following marker values were obtained: 1st day: PICP 609 (583; 635) ng/ml, PIIINP 26 (18.9; 34.9) ng/ml; 12th day: PICP 588 (580; 561) ng/ml, PIIINP 24.2 (18.6; 30.3) ng/ml. The following significant correlations were revealed: PICP 1st day / isovolumic contraction time – IVCT (m/s) 12th day, r=−0.68, p=0.042; PICP 1st day / Tei Index 12th day, r=−0.72, p=0.028; PICP 1st day / diastolic rigidity 12th day, r=−0.74, p=0.021; PIIINP 1st day/age, r=0.55, p=0.016; PIIINP 1st day/ body mass index (BMI), r=−0.59, p=0.009; PIIINP 1st day / E (cm/s) 1st day, r=0.72, p=0.018; PIIINP 1st day / Em /FPV 1st day, r=0.78, p=0.007; PIIINP 12th day / Em / FPV 1st day, r=0.65, p=0.041; PIIINP 12th day / E (cm/s) 1st day, r=0.67, p=0.033; PIIINP 12th day / E / Em) 12th day, r=0.70, p=0.023; PIIINP 12th day / Em/FPV 12th day, r=0.73, p=0.014. Conclusions The data obtained indicates the correlation between serum markers of myocardial fibrosis and the indices of echocardiography, as well as age. We conclude that, all the markers listed above, are able to represent myocardial remodeling in patients with STEMI. Funding Acknowledgement Type of funding source: None

Residual Syntax Score

The purpose of this study is to investigate the relation between residual SYNTAX score (rSS) and contrast-induced nephropathy (CIN) development in patients with non-ST segment elevation myocardial infarction (NSTEMI) with normal or near-to-normal left ventricular ejection fraction (LVEF) who underwent percutaneous coronary intervention (PCI). A total of 306 patients who underwent PCI with NSTEMI were included in our study. SYNTAX scores were calculated for the periods before and after PCI. Patients were divided into 2 groups as developed CIN following PCI (CIN +) and patients did not (CIN −). Fifty-four (17.6%) of patients who were included in the study developed CIN. Age ( P = .001) and rSS ( P = .002) were significantly higher and LVEF was lower ( P = .034) in the CIN (+) group. Age ( P = .031, odds ratio [OR]: 1.031, 95% CI, 1.003-1.059) and rSS ( P = .04, OR: 1.036, 95% CI, 1.002-1.071) were independent predictors for CIN. In receiver operating characteristic analyses, when the cutoff value of rSS was taken as 3.5, it determined CIN with 79% sensitivity and 65% specificity. Contrast-induced nephropathy may develop more frequently in patients with increased rSS value. The rSS may be useful to follow-up these patients for CIN development.

Elevated Heart Rate

Background: Elevated heart rate is associated with poor clinical outcome in patients with acute myocardial infarction. However, in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention the importance of elevated heart rate in the very early phase remains unknown. We evaluated the impact of elevated heart rate in the very early pre-hospital phase of ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention on cardiovascular magnetic resonance markers of reperfusion success and clinical outcome. Methods: In this DANAMI-3 substudy, 1560 ST-segment elevation myocardial infarction patients in sinus rhythm without cardiogenic shock were included in the analyses of clinical outcome and 796 patients underwent cardiovascular magnetic resonance to evaluate area at risk, infarct size and left ventricular ejection fraction. Heart rate was assessed on the first electrocardiogram with ST-elevation (time of diagnosis). Results: Despite equal area at risk (33%±11 versus 36%±16, p=0.174) patients with a pre-hospital heart rate ⩾100 beats per minute developed larger infarcts (19% (interquartile range, 9–17) versus 11% (interquartile range, 10–28), p=0.001) and a lower left ventricular ejection fraction (54%±12 versus 58%±9, p=0.047). Pre-hospital heart rate ⩾100 beats per minute was independently associated with an increased risk of all-cause mortality and heart failure (hazard ratio 2.39 (95% confidence interval 1.58–3.62), p<0.001). Conclusions: Very early heart rate ⩾100 beats per minute in ST-segment elevation myocardial infarction was independently associated with larger infarct size, reduced left ventricular ejection fraction and an increased risk of all-cause mortality and heart failure, and thus serves as an easily obtainable and powerful tool to identify ST-segment elevation myocardial infarction patients at high risk.
