INTRODUCTION: In patients with non-ST-elevation myocardial infarction (NSTEMI), the best timing for coronary angiography is not definitely established, although it is recognized that in high-risk patients it should be performed within the first 24 hours. The aim of this work was to describe the evolution over time of the use of an invasive strategy in the treatment of NSTEMI and in-hospital mortality. METHODS: We performed a retrospective analysis of patients admitted with NSTEMI included in the Portuguese Registry on Acute Coronary Syndromes (ProACS) between 2002 and 2015...

BACKGROUND: Beyond lipid-lowering effects, early statin treatment has beneficial effects on prognosis after acute coronary syndrome. Infarct related artery patency before percutaneous coronary intervention is known to be a strong predictor of improved clinical outcome. AIM: We aimed to investigate the effects of chronic statin treatment before admission on the infarct related artery patency after infarction. METHODS: In this study, 938 ST elevation myocardial infarction patients admitted to the hospital within the first 12 hours of symptom onset were prospectively enrolled (682 male, 256 female; mean age 58...

Epidemiological studies have provided evidence that traffic noise exposure is linked to cardiovascular diseases such as arterial hypertension, myocardial infarction and stroke. Noise is a non-specific stressor that activates the autonomous nervous system and endocrine signaling. According to the noise reaction model introduced by Babisch and colleagues, chronic low levels of noise can cause so called non-auditory effects, such as disturbances of activity, sleep and communication, which can trigger a number of emotional responses, including annoyance and subsequent stress...

Acute kidney injury (AKI) is one of the most common complications during hospitalization in various clinical settings. The goal of this review was to assess the incidence of AKI in acute myocardial infarction patients (AMI), how this incidence is affected by the diverse definitions, and if there is variability in the reported rates over recent years. Additionally, we sought to appraise the impact of AKI on short- and long-term prognosis of these patients. Finally, we report on the current preventive measures as they are suggested in the current guidelines of various societies, we comment on the evidence that support them, and we review the literature for other proposed therapeutic strategies, which either failed to prove their efficacy or they are not adequately confirmed yet...

Identification of the adult cardiac stem cells (CSCs) has offered new therapeutic possibilities for treating ischemic myocardium. CSCs positive for the cell surface antigen c-Kit are known as the primary source for cardiac regeneration. Accumulating evidence shows that chemokines play important roles in stem cell homing. Here we investigated molecular targets to be utilized in modulating the mobility of endogenous CSCs. In a four week follow-up after experimental acute myocardial infarction (AMI) with ligation of the left anterior descending (LAD) coronary artery of Sprague-Dawley rats c-Kit+ CSCs redistributed in the heart...

Kounis syndrome defined as the appearance of acute coronary syndrome in the context of an allergic reaction is a relatively rare phenomenon. There are three variants of this syndrome in which the patient presents with symptoms of an acute chest. Herein, we describe a case of an 83-year-old woman who demonstrated type I variant of Kounis syndrome in response to vancomycin administration. After initialisation of vancomycin, she became unresponsive and an ECG demonstrated ST changes consistent with inferior-lateral myocardial infarction...

BACKGROUND: The local inflammatory tissue response after acute myocardial infarction (MI) determines subsequent healing. Systemic interaction may induce neuroinflammation as a precursor to neurodegeneration. OBJECTIVES: This study sought to assess the influence of MI on cardiac and brain inflammation using noninvasive positron emission tomography (PET) of the heart-brain axis. METHODS: After coronary artery ligation or sham surgery, mice (n = 49) underwent serial whole-body PET imaging of the mitochondrial translocator protein (TSPO) as a marker of activated macrophages and microglia...

BACKGROUND: Mortality in patients with acute myocardial infarction (AMI) has improved substantially with modern therapy including percutaneous coronary interventions (PCI) but remains high in certain subgroups such as patients presenting with overt cardiogenic shock. However, the risk for AMI in patients presenting acutely with signs of heart failure but without cardiogenic shock is less well described. We aimed to identify risk factors for mortality in AMI patients with heart failure without overt cardiogenic shock...

COMMENT
Tanuka Datta, Allen J Solomon
Approved in 1989 for the management of treatment-resistant schizophrenia, Clozapine is a last-line atypical antipsychotic drug used with increasing frequency. In addition to its well-known side effect of agranulocytosis, this drug also carries with it rare but serious adverse cardiovascular risk of myocarditis. We present a patient on Clozapine who was admitted to the cardiology service with chest pain, ST segment elevations and elevated troponin concerning for acute myocardial infarction. Evaluation with imaging revealed decreased left ventricular function, however, no coronary artery disease was present on catheterization; findings consistent with a diagnosis of myocarditis...

Platelet activation plays a central role in triggering and complicating acute coronary syndromes, especially in case of stent thrombosis and myocardial infarction. On top of aspirin, P2Y12-inhibitors are successfully used to treat and prevent these events for a duration of one year after an acute coronary episode or 6 months after drug-eluting stent implantation. However, patients with acute coronary syndromes remain at heightened risk for recurrent ischemic events after the recommended durations of P2Y12-inhibitors and therefore, prolonging treatment is often considered in clinical practice...

Background: Myocardial ischaemia-reperfusion injury is a major cause of mortality and morbidity in the developed world. Many approaches have been investigated to counteract the pathological consequences associated with acute myocardial infarction (AMI) and cardiac remodelling. It is accepted that inflammation, and therefore activation of the complement pathway, is a crucial step in the pathogenesis of this injury, and many attempts have been made to ameliorate the infarction and consequent dysfunction using anticomplement therapy, with mixed success...

OBJECTIVE: To determine long-term cardiovascular risk after TIA and to identify the factors associated with increased risk. METHODS: This was a prospective observational registry of TIA patients admitted to the emergency room of our tertiary stroke center from June 2006 to January 2016. New vascular events (NVEs) were recorded from 3 months after TIA onset until June 2017, including both stroke and nonstroke events (coronary and peripheral disease). We registered TIA etiology, age, sex, vascular risk factors, radiologic data, and clinical TIA features and analyzed these variables in relation to NVE long-term risk...
