Erectile dysfunction significantly affects quality of life in young men. Authors have evaluated erectile function in men with coronary artery disease (CAD) and the relationship between the degree of erectile dysfunction (ED) and the age of their first acute myocardial infarction (AMI). The incidence of erectile dysfunction in three groups of patients of AMI survivors was investigated: AMI survivors younger than 45 years, AMI survivors older than 65 years, and normal male population aged between 30 and 60 years...

Recent studies suggested that gut microbiota was involved in the development of coronary artery disease. However, the changes of gut microbiota following acute myocardial infarction (AMI) remain unknown. In this study, a total of 66 male Wistar rats were randomly divided into control, AMI and SHAM groups. The controls (n = 6) were sacrificed after anesthesia. The AMI model was built by ligation of left anterior descending coronary artery. The rats of AMI and SHAM groups were sacrificed at 12 h, 1 d, 3 d, 7 d and 14 d post-operation respectively...

BACKGROUND: MicroRNAs (miRs) have shown to exert fibrotic and anti-fibrotic effects in preclinical models of acute myocardial infarction (AMI). The aim of this study was to evaluate miR-1, miR-21, miR-29b and miR-92a as circulating biomarkers for adverse ventricular remodeling (AVR) in post-AMI patients. METHODS: Plasma levels of miR-1, miR-21, miR-29b and miR-92a were measured in 44 patients of the SITAGRAMI trial population at day 4, day 9 and 6month after AMI and in 18 matched controls (CTL)...

Patients with acute myocardial infarction (AMI) who are transferred are less likely than directly admitted patients to receive outpatient follow-up within 30 days and are more likely to be readmitted. In 2015, we launched a clinic where post-AMI patients (direct admits and transfers) are seen within 1 week of hospital discharge. We compared short- and long-term clinical outcomes of patients who were transferred to patients who were directly admitted to our institution to determine the impact of transfer status on early outpatient follow-up and clinical outcomes...

RATIONALE: Intracoronary infusion of bone marrow (BM) mononuclear cells after acute myocardial infarction (AMI) has led to limited improvement in left ventricular function. Although experimental AMI models have implicated cytokine-related impairment of progenitor cell function, this response has not been investigated in humans. OBJECTIVE: To test the hypothesis that peripheral blood (PB) cytokines predict BM endothelial progenitor cell colony outgrowth and cardiac function after AMI...

Aims: Experimental evidence suggests that telomere length (TL) is shortened by oxidative DNA damage, reflecting biological aging. We explore the value of blood (BTL) and vascular TL (VTL) as biomarkers of systemic/vascular oxidative stress in humans and test the clinical predictive value of BTL in acute myocardial infarction (AMI). Methods and results: In a prospective cohort of 290 patients surviving recent AMI, BTL measured on admission was a strong predictor of all-cause [hazard ratio (HR) [95% confidence interval (CI)]: 3...

BACKGROUND: Post-infarction ventricular septal rupture (VSR) is a rare but lethal mechanical complication of an acute myocardial infarction (AMI). Survival to 1 month without intervention is 6%. Given high surgical mortality, transcatheter closure has emerged as a potential strategy in selected cases. Indian data on percutaneous device closure of post AMI-VSR is scarce hence we report our single-centre experience with ASD occluder device (Amplatzer and lifetech) for closure of post-AMI VSR...

Despite early revascularization, remodeling and dysfunction of the left ventricle (LV) after acute myocardial infarction (AMI) remain important therapeutic targets. Intermittent pacing therapy (IPT) of the LV can limit infarct size, when applied during early reperfusion. However, the effects of IPT on post-AMI LV remodeling and infarct healing are unknown. We therefore investigated the effects of IPT on global LV remodeling and infarct geometry in swine with a 3-day old AMI. For this purpose, fifteen pigs underwent 2 h ligation of the left circumflex coronary artery followed by reperfusion...

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...

What is the central question of this study? In a rat model of acute myocardial infarction (AMI), we investigated the effect of Tongxinluo (TXL) treatment. Does TXL activate autophagy and attenuate apoptosis of cardiomyocytes through the AMPK pathway to facilitate survival of cardiomyocytes and improve cardiac function? What is the main finding and its importance? Major findings are as follows: (i) TXL treatment preserved cardiac function and reduced ventricular remodelling, infarct size and inflammation in rat hearts after AMI; (ii) TXL treatment dramatically increased autophagy and inhibited apoptosis in myocardium; and (iii) the AMPK signalling pathway played a crucial role in mediating the beneficial effects of TXL...

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...

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...
