Objective We evaluated the effects of atorvastatin and ticagrelor combination therapy on renal function and the levels of suppression of tumorigenicity 2 (ST2) and interleukin 33 (IL-33) in patients with ST-segment elevation myocardial infarction (STEMI). Methods Eighty-four STEMI patients who underwent emergency percutaneous coronary intervention at our hospital from January 2015 to March 2018 were retrospectively analyzed and divided into a control group (n = 44) and an observation group (n = 40). The control group was treated with atorvastatin as routine STEMI treatment, whereas the observation group was concurrently administered ticagrelor. Results After treatment, significantly better outcomes were observed in the control group than in the observation group in terms of clinical indices, including chest pain relief, enzyme levels, duration of reperfusion-associated arrhythmia, and depression of the ST segment. Both groups exhibited improvements in cardiac ultrasound indices, whereas the observation group showed lower left ventricular end-diastolic and end-systolic diameters and higher left ventricular ejection fractions than the control group. Conclusions Atorvastatin and ticagrelor combination therapy is clinically effective and safe for STEMI patients as it reduces the degree of myocardial infarction, protects the heart and renal functions, improves inflammation, and reduces adverse cardiac event incidences.

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.

Objective: Study on the effect of nursing management in different levels and areas in emergency treatment of patients with acute ST segment elevation myocardial infarction. Methods: 200 patients with acute ST segment elevation myocardial infarction admitted by our hospital from January 2018 to October 2019 were divided into observation group and control group according to the nursing mode of patients, with 100 cases in each group. The patients in the control group were given routine emergency care, and the patients in the observation group were given graded and partitioned nursing management. Result: The time of emergency treatment, coronary angiography and stent placement were compared between the two groups. The results showed that the time of observation group was significantly shorter than that of control group (P < 0.05). The results showed that the time of the observation group was significantly shorter than that of the control group (P < 0.05). The incidence of complications was 11.00% in the control group and 1.00% in the observation group. There was statistical significance between the two groups (P < 0.05). The nursing satisfaction of the control group was 80.00%, and that of the observation group was 96.00%. There was statistical significance between the two groups (P < 0.05). Conclusion: The application effect of grading and zoning nursing management in the first aid of patients with acute ST segment elevation myocardial infarction is better. It can effectively shorten the waiting time of patients, reduce nursing complications, improve nursing satisfaction, and effectively improve the effect of first aid, which is worth popularizing.

Aims To investigate the different risk factors among different subtypes of patients with acute coronary syndrome (ACS). Methods A total of 296 patients who had ACS were retrospectively enrolled. Blood and echocardiographic indices were assessed within 24 hours after admission. Differences in risk factors and Gensini scores of coronary lesions among three groups were analyzed. Results Univariate analysis of risk factors for ACS subtypes showed that age, and levels of fasting plasma glucose, amino-terminal pro-brain natriuretic peptide, and creatine kinase isoenzyme were significantly higher in patients with non-ST-segment elevation myocardial infarction (NSTEMI) than in those with unstable angina pectoris (UAP). Logistic multivariate regression analysis showed that amino-terminal pro-brain natriuretic peptide and the left ventricular ejection fraction (LVEF) were related to ACS subtypes. The left ventricular end-diastolic diameter was an independent risk factor for UAP and ST-segment elevation myocardial infarction (STEMI) subtypes. The severity of coronary stenosis was significantly higher in NSTEMI and STEMI than in UAP. Gensini scores in the STEMI group were positively correlated with D-dimer levels (r = 0.429) and negatively correlated with the LVEF (r = −0.602). Conclusion Different subtypes of ACS have different risk factors. Our findings may have important guiding significance for ACS subtype risk assessment and clinical treatment.

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

SummaryThe role of platelet-leukocyte interaction in the infarct myocardium still remains unveiled. We aimed to determine the linkage of platelet activation to post-infarct left ventricular remodelling (LVR) process. REMODELING was a prospective, observational, cohort trial including patients (n = 150) with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention. Patients were given aspirin plus clopidogrel therapy (600 mg loading and 75 mg daily). Platelet reactivity (PRU: P2Y12 Reaction Units) was assessed with VerifyNow P2Y12 assay on admission. Transthoracic echocardiography was performed on admission and at one-month follow-up. The primary endpoint was the incidence of LVR according to PRU-based quartile distribution. LVR was defined as a relative ≥ 20 % increase in LV end-diastolic volume (LVEDV) between measurements. Adverse LVR was observed in 36 patients (24.0 %). According to PRU quartile, LVR rate was 10.8 % in the first, 23.1 % in the second, 27.0 % in the third, and 35.1 % in the fourth (p = 0.015): the optimal cut-off of PRU was ≥ 248 (area under curve: 0.643; 95 % confidence interval: 0.543 to 0.744; p = 0.010). LVR rate also increased proportionally according to the level of high sensitivity-C reactive protein (hs-CRP) (p = 0.012). In multivariate analysis, the combination of PRU (≥ 248) and hs-CRP (≥ 1.4 mg/l) significantly increased the predictive value for LVR occurrence by about 21-fold. In conclusion, enhanced levels of platelet activation and inflammation determined the incidence of adverse LVR after STEMI. Combining the measurements of these risk factors increased risk discrimination of LVR. The role of intensified antiplatelet or anti-inflammatory therapy in post-infarct LVR process deserves further study.
