Extracorporeal shockwave myocardial revascularization (ESMR) is one of the new treatment options for refractory angina pectoris (RAP), and some studies have indicated its effectiveness. A single-arm prospective trial to assess the feasibility of ESMR using Cardiospec for patients with post-acute myocardial infarction (AMI) and RAP was designed and performed. The patients were treated with 9 sessions of ESMR to the ischemic areas for 9 weeks. The feasibility measures included echocardiography; cardiac magnetic resonance imaging; troponin T, creatine kinase-MB (CK-MB), and brain natriuretic peptide testing; and a Seattle Angina Questionnaire (SAQ) survey...

BACKGROUND: Treatment with renin-angiotensin system (RAS) inhibitors might restrain the structural/electrical remodeling associated with atrial fibrillation (AF). Limited evidence exists regarding the potential benefits of RAS inhibition post-acute myocardial infarction (AMI) in patients with AF. This study sought to assess the association between RAS inhibition and all-cause mortality and new-onset AF in patients with/without congestive heart failure (CHF) post-AMI. METHODS AND RESULTS: Patients hospitalized for AMI between 2006 and 2012 were identified in Swedish registries...

BACKGROUND: Young women (≤55 years of age) with acute myocardial infarction (AMI) have higher mortality risk than similarly aged men. Elevated inflammatory markers are associated with an increased risk of cardiovascular outcomes after AMI, but little is known about whether young women have higher inflammatory levels after AMI compared with young men. METHODS AND RESULTS: We assessed sex differences in post-AMI inflammatory markers and whether such differences account for sex differences in 12-month health status, using data from 2219 adults with AMI, 18 to 55 years of age, in the United States...

In recent years, there has been growing public awareness and increasing attention to young women with acute myocardial infarction (AMI), who represent an extreme phenotype. Young women presenting with AMI may develop coronary disease by different mechanisms and often have worse recoveries, with higher risk for morbidity and mortality compared with similarly aged men. The purpose of this cardiovascular perspective piece is to review recent studies of AMI in young women. More specifically, we emphasize differences in the epidemiology, diagnosis, and management of AMI in young women (when compared with men) across the continuum of care, including their pre-AMI, in-hospital, and post-AMI periods, and highlight gaps in knowledge and outcomes that can inform the next generation of research...

Tongxinluo (TXL) has been demonstrated to have a protective role during ischemia/reperfusion after acute myocardial infarction (AMI), but the long-term effects and the underlying mechanisms are still unknown. This study aimed to investigate whether TXL could have an effect on apoptosis or autophagy of cardiomyocytes through the AMP-activated protein kinase (AMPK) pathway. Male, Sprague-Dawley rats (n = 75) were randomly divided to sham, control, TXL (4 mg kg(-1)  d(-1) orally), compound C (intraperitoneal injection at 10 mg kg(-1)  d(-1) ), and TXL + compound C groups...

Stem cell antigen-1-positive (Sca-1+) cardiac stem cells (CSCs) therapy for myocardial regeneration following acute myocardial infarction (AMI) is limited by insufficient cell viability and a high rate of apoptosis, due to the poor regional microenvironment. Resveratrol, which is a compound extracted from red wine, has been reported to protect myocardial tissue post‑AMI by increasing the expression of angiogenic and chemotactic factors. The present study aimed to investigate the effects of resveratrol on Sca‑1+ CSCs, and to optimize Sca‑1+ CSCs therapy for myocardial regeneration post‑AMI...

Psychosocial factors are known to impact depressive symptoms across clinical populations. Learned helplessness has the potential of affecting depressive symptoms following acute myocardial infarction (AMI), though little is known about this relationship. The purpose of this study was to examine the relationship between learned helplessness and depressive symptoms in patients following an AMI. Using a descriptive cross-sectional design, participants with a diagnosed AMI within the past 12 months were recruited...

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...

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)...
