Abstract Background Controversy exists regarding the use of beta-blockers (BBs) among patients with acute myocardial infarction (AMI) in contemporary reperfusion era. Previous studies predominantly focused on beta-blockers prescribed at discharge, and the effect of long-term adherence to beta-blocker on major adverse cardiovascular events (MACE) remains unclear. Objective To explore the association between long-term beta-blocker use patterns and MACE among contemporary AMI patients. Methods We enrolled 7860 patients with AMI, who were discharged alive and prescribed with BBs based on CAMI registry from January 2013 to September 2014. Patients were divided into two groups according to BBs use pattern: Always users group (n=4476) were defined as patients reporting BBs use at both 6- and 12-month follow-up; Inconsistent users group were defined as patients reporting at least once not using BBs at 6- or 12-month follow-up. Primary outcome was defined as MACE at 24-month follow-up, including all-cause death, non-fatal MI and repeat-revascularization. Multivariable cox proportional hazards regression model was used to assess the association between BBs and MACE. Results Baseline characteristics are shown in table 1. At 2-year follow-up, 518 patients in inconsistent users group (15.6%) and 548 patients in always users group (12.3%) had MACE. After multivariable adjustment, inconsistent use of BBs was associated with higher risk of MACE (HR: 1.323, 95% CI: 1.171–1.493, p<0.001).

Background: Myocardial ischemia-reperfusion (MI/R) injury is a significant clinical problem without effective therapy. Unbiased omics approaches may reveal key MI/R mediators to initiate MI/R injury. Methods: We used a dynamic transcriptome analysis of mouse heart exposed to various MI/R periods to identify S100a8/a9 as an early mediator. Using loss/gain-of-function approaches to understand the role of S100a8/a9 in MI/R injury, we explored the mechanisms through transcriptome and functional experiment. Dynamic serum S100a8/a9 levels were measured in patients with acute myocardial infarction before and after percutaneous coronary intervention. Patients were prospectively followed for the occurrence of major adverse cardiovascular events. Results: S100a8/a9 was identified as the most significantly upregulated gene during the early reperfusion stage. Knockout of S100a9 markedly decreased cardiomyocyte death and improved heart function, whereas hematopoietic overexpression of S100a9 exacerbated MI/R injury. Transcriptome/functional studies revealed that S100a8/a9 caused mitochondrial respiratory dysfunction in cardiomyocytes. Mechanistically, S100a8/a9 downregulated NDUF gene expression with subsequent mitochondrial complex I inhibition via Toll-like receptor 4/Erk–mediated Pparg coactivator 1 alpha/nuclear respiratory factor 1 signaling suppression. Administration of S100a9 neutralizing antibody significantly reduced MI/R injury and improved cardiac function. Finally, we demonstrated that serum S100a8/a9 levels were significantly increased 1 day after percutaneous coronary intervention in patients with acute myocardial infarction, and elevated S100a8/a9 levels were associated with the incidence of major adverse cardiovascular events. Conclusions: Our study identified S100a8/a9 as a master regulator causing cardiomyocyte death in the early stage of MI/R injury via the suppression of mitochondrial function. Targeting S100a8/a9-intiated signaling may represent a novel therapeutic intervention against MI/R injury. Clinical Trial Registration: URL: https://www.clinicaltrials.gov .

Background: Elevated blood urea nitrogen (BUN), blood glucose, and alteration sodium levels are common among patients with acute myocardial infarction (AMI). These parameters to be widely investigated to assess the prognosis in AMI patients. However, the combination of these parameters (BUN, blood glucose, and sodium) calculated by a certain formula in the form of plasma osmolality has not been widely studied to assess the prognosis of patients with acute myocardial infarction. This study aims to assess plasma osmolality in predicting hospital major adverse cardiovascular events (MACEs) among AMI patients. Methods: Data were collected from 118 consecutive patients with AMI in Cardiac Centre Haji Adam Malik General Hospital Medan. We measured admission plasma osmolality [1,86 (Na+) + BUN/2,8 + Glucose/18+9]. Then we observed in hospital Major Adverse Cardiovascular Outcomes (MACEs) which consist of cardiovascular mortality, acute heart failure, malignant arrhythmia, and cardiogenic shock. Statistical analysis was performed using mean difference, logistic regression, and receiver operating curve (ROC). Result: Among 118 patients, MACEs were observed in 49 (41.5%) patients with the most common MACEs was acute heart failure (25.4%). Bivariate analysis showed a significant relationship between the plasma osmolality and in hospital MACEs (p < 0.001). The plasma osmolality AUC prediction value was 78.9%. The optimal cut-off value was 279.9 mOsm/kg (sensitivity 81.6%; specificity 75.4%). In multivariate logistic regression analysis, the plasma osmolality was the strongest predictor with an OR value of 10.542 (95% CI 2.694-41.255; p-value <0.001). Conclusions: Among AMI patients, high plasma osmolality value (≥280 mOsm/kg) is a better predictor of in-hospital MACEs than its components separately(BUN, glucose level, sodium).

Abstract Background and Objectives: There is currently no evidence regarding the role of plasma Sirtuin2 (SIRT2) level in heart failure after acute myocardial infarction (AMI) yet. This study assessed the relationship between plasma SIRT2 level and AMI, and also investigated the association of plasma SIRT2 level with major adverse cardiovascular events (MACE) and heart failure after AMI. Methods and Results: A total of 129 AMI patients were included in the present study. The major adverse cardiovascular events (MACE) and heart failure were recorded during hospitalization and follow-up (12 months) after discharge. According to the 75th percentile value of plasma SIRT2 level, we divided all the AMI patients into two groups: high level group (plasma SIRT2 level≥109.0pg/ml) and low level group (plasma SIRT2 level <109.0pg/ml). Compared with the low level group, the high level group had higher prercentage of Killip class≥3 (P<0.001), left ventricular ejection fraction(LVEF) <50% (P=0.007) or even <40% (P=0.012), use of breathing machine(P=0.003), and higher plasma brain natriuretic peptide (BNP) level (P=0.006). Multivariate regression analysis showed that there were higher risks of MACE (hazard ratio (HR)=11.20 [95% confidence interval (CI): 3.18-39.52, P<0.001]) and heart failure (HR=27.10 [95%CI 4.65-157.83, P<0.001]) in the high level group. Conclusions: The present study suggested that plasma SIRT2 level is a promising biomarker to predict heart failure and MACE after AMI.
