AIMS: Cardiac arrhythmias following acute myocardial infarction (AMI) can be associated with major adverse cardiovascular events. Data on the "real incidence" of post-MI arrhythmias are limited. We aimed to determine the rate and burden of cardiac arrhythmias by the use of insertable cardiac monitors (ICM) in patients with preserved left ventricular ejection fraction (LVEF) after AMI. METHODS AND RESULTS: In this prospective observational study, patients with LVEF ≥40% who underwent PCI within 7 days following AMI were enrolled to receive an ICM...

BACKGROUND: In the setting of an acute myocardial infarction (AMI), although the most common etiology of a left ventricular (LV) mass identified on multimodality cardiovascular imaging is a thrombus, other possibilities including a vegetation or tumor should be entertained within the differential diagnosis. CASE PRESENTATION: We describe a case of a 43-year-old Caucasian female post AMI diagnosed with a mid-cavitary mass within the LV. Although echocardiography and cardiovascular MRI (CMR) suggested that the mass was a thrombus, given the context of the recent AMI, exploration and surgical excision was completed by the surgeon due to the potential for the mass to embolize...

OBJECTIVE: The aim of the study was to examine how psychological stress changes over time in young and middle-aged patients after experiencing an acute myocardial infarction (AMI) and whether these changes differ between men and women. METHODS: We analyzed data obtained from 2358 women and 1151 men aged 18 to 55 years hospitalized for AMI. Psychological stress was measured using the 14-item Perceived Stress Scale (PSS-14) at initial hospitalization and at 1 month and 12 months after AMI...

Conventional cardiovascular risk factors (CVRF) are accepted to identify asymptomatic individuals with high risk of acute myocardial infarction (AMI). However, AMI affects many patients previously classified at low risk. New biomarkers are needed to improve risk prediction. We propose to evaluate the NLRP3-inflammasome complex as a potential CVR indicator in healthy males and post-AMI patients and compare both groups by known CVRFs. We included 109 men with no history of cardiovascular disease (controls) and 150 AMI patients attending a cardiac rehabilitation program...

AIM: To evaluate the association of post-acute myocardial infarction (AMI) plasma haptoglobin (Hp) levels with long-term overall survival in AMI patients. METHODS AND RESULTS: Patients who were diagnosed of AMI were recruited and their Hp phenotypes and plasma levels were determined. According to previously reported cutoff point for Hp level (288.4ng/ml), patients were classified as higher Hp group (>288.4ng/ml) and lower Hp group (≤288.4ng/ml). The primary outcome was overall survival...

BACKGROUND: Adipose-derived stromal cells (ASCs) are a promising new therapeutic option for patients with acute myocardial infarction (AMI). Previously, we found that ASCs coupled to antibody-targeted microbubbles (StemBells [StBs]) improved cardiac function when administered intravenously 7 days post-AMI in rats. In this study, we compared the efficacy of intravenous StB administration at different administration time points following AMI in rats. METHODS: AMI, followed by reperfusion, was induced in four groups of male Wistar rats, which subsequently received an intravenous 1 × 10(6) StB bolus 1 day post-AMI (StB1; n = 8), 7 days post-AMI (StB7; n = 9), at both time points (StB1+7; n = 7) or neither (Control; n = 7)...

Qishen granules (QSG), a traditional Chinese medicine, have been prescribed widely in the treatment of coronary heart diseases. Previous studies demonstrated that QSG had anti-inflammatory and cardio-protective effects in mice with acute myocardial infarction (AMI). However, the mechanisms by which QSG attenuate inflammation and prevent post-AMI heart failure (HF) are still unclear. In this study, we explored the anti-inflammatory mechanisms of QSG by in vitro and in vivo experiments. A novel inflammatory injury model of H9C2 cells was induced by lipopolysaccharide (LPS)-stimulated macrophage-conditioned media (CM)...

The complement system plays an important role in the inflammatory response subsequent to acute myocardial infarction (AMI). The aim of this study is to create a systematic overview of studies that have investigated therapeutic administration of complement inhibitors in both AMI animal models and human clinical trials. To enable extrapolation of observations from included animal studies toward post-AMI clinical trials, ex vivo studies on isolated hearts and proof-of-principle studies on inhibitor administration before experimental AMI induction were excluded...

In the Survival of Myocardial Infarction Long-term Evaluation (SMILE) 1, 3, and 4 studies, early administration of zofenopril in acute myocardial infarction showed to be prognostically beneficial versus placebo or ramipril. The SMILE-2 showed that both zofenopril and lisinopril are safe and showed no significant differences in the incidence of major cardiovascular (CV) complications. In this pooled analysis of individual data of the SMILE studies, we evaluated whether the superior efficacy of zofenopril is maintained also in patients with ≥1 CV risk factor (CV+, n = 2962) as compared to CV- (n = 668)...

INTRODUCTION: Hospitalization for acute myocardial infarction (AMI) is an opportune time to counsel smokers to quit. Studies have demonstrated lower short-term mortality for counseled versus non-counseled smokers; yet, little is known about the long-term survival benefits of post-AMI smoking-cessation counseling (SCC). METHODS: Data from the Cooperative Cardiovascular Project, a prospective cohort study of elderly patients with AMI between 1994 and 1996 with >17 years of follow-up, were used to evaluate the association of SCC with short- and long-term mortality in smokers with AMI...

PURPOSE: Cardiac cell therapy is a promising treatment for acute myocardial infarction (AMI), leading to cardiac function improvement. However, whether it translates into quality of life (QoL) improvement is unclear. We hypothesized that administration of bone marrow cells (BMC) to patients with AMI improves QoL. METHODS: In the multicenter BONAMI trial (NCT00200707), patients with reperfused AMI and decreased myocardial viability were randomized to intracoronary autologous BMC infusion (n = 52) or state-of-the-art therapy (n = 49)...

S100 Ca2+-binding protein A1 (S100A1) is an important regulator of myocardial contractility. The aim of the present study was to identify the underlying mechanisms of S100A1 activity via profiling the protein expression in rats administered with an S100A1 adenovirus (Ad‑S100A1‑EGFP) following acute myocardial infarction (AMI). LTQ OrbiTrap mass spectrometry was used to profile the protein expression in the Ad‑S100A1‑EGFP and control groups post‑AMI. Using Protein Analysis Through Evolutionary Relationships (PANTHER) analysis, 134 energy metabolism‑associated proteins, which comprised 20 carbohydrate metabolism‑associated and 27 lipid metabolism associated proteins, were identified as differentially expressed in the Ad‑S100A1‑EGFP hearts compared with controls...

INTRODUCTION: Ventricular tachyarrhythmias (ventricular tachycardia and ventricular fibrillation) can lead to aborted cardiac arrest or sudden cardiac death in patients with poor left ventricular function early after acute myocardial infarction (AMI). Although it has been shown that the implantable cardioverter defibrillator (ICD) can treat ventricular tachyarrhythmias and save lives in patients with ischemic cardiomyopathy, it's use during the early phase post AMI has not been shown to reduce mortality...
