Aim. Currently, there is no method which accurately predicts an adverse outcome of heart failure with a preserved left ventricular ejection fraction (HFpEF) upon ST-segment elevation myocardial infarction (STEMI). Here we studied the prognostic significance of procollagen type I C-terminal propeptide (PICP) and procollagen type III N-terminal propeptide (PIIINP) in patients with post-STEMI HFpEF.Material and Methods. The study included 83 patients (60 men and 23 women) with post-STEMI HFpEF (left ventricular EF ≥ 50%) and 20 ageand gender-matched healthy controls. Serum concentrations of PICP and PIIINP were measured on the 1st day of hospitalization using enzyme-linked immunosorbent assay with the following calculation of PICP/PIIINP ratio.Results. Serum PICP and PIIINP on the 1st day of STEMI significantly (3.4-fold) exceeded the values of the control group and were as follows: PIIINP: 26.0 (18.9; 34.9) ng/mL (р = 0.047); PICP: 609.0 (583.0; 635.0) ng/mL (р = 0.049).Conclusion. Elevated values of procollagens indicate that cardiac fibrosis commences within the 24 hours after STEMI onset. The pivotal role of cardiac fibrosis in the formation of diastolic dysfunction suggests the usefulness of serum procollagens to predict the development of HFpEF in a long-term period upon 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.

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.
