Surgeries to correct congenital heart diseases are increasing in Brazil and worldwide. However, even with the advances in surgical techniques and perfusion, some cases, especially the more complex ones, can develop heart failure and death. A retrospective study of patients who underwent surgery for correction of congenital heart diseases with cardiopulmonary bypass (CPB) in a university tertiary-care hospital that died, showed infarction in different stages of evolution and scattered microcalcifications in the myocardium, even without coronary obstruction...

BACKGROUND: The migration of cardiac fibroblasts to the infarct region plays a major role in the repair process after myocardial necrosis or damage. However, few studies investigated whether early hypoxia in cardiomyocytes induces the migration of cardiac fibroblasts. The purpose of this study was to assess the role of metabolites of early hypoxic cardiomyocytes in the induction of cardiac fibroblast migration. METHODS: Neonatal rat heart tissue was digested with a mixture of trypsin and collagenase at an appropriate ratio...

BACKGROUND: Aortic valve predilation with balloon aortic valvuloplasty (BAV) is recommended before transcatheter aortic valve implantation (TAVI), despite limited data around the requirement of this preprocedural step and the potential risks of embolization. This study aimed to investigate the trends in practice and associations of BAV on short-term outcomes in the UK TAVI registry. METHODS AND RESULTS: Eleven clinical endpoints were investigated, including 30-day mortality, myocardial infarction, aortic regurgitation, valve dysfunction, and composite early safety...

INTRODUCTION: Optimal timing of surgical treatment for infective endocarditis (IE) complicated by intracranial hemorrhage remains controversial. PRESENTATION OF CASE: A 43-year-old man with IE received appropriate antibiotic therapy but had recurrence of cerebral infarction and intracranial hemorrhage (ICH). Emergency valve surgery was performed 2days after ICH onset because of heart failure and recurrence of cerebral complications. Postoperatively, he showed no neurologic symptoms; neuroimaging showed no enlargement of ICH...

Cardiac fibrosis (CF), a repairing process following myocardial infarction (MI), is characterized by abnormal proliferation of cardiac fibroblasts and excessive deposition of extracellular matrix (ECM) resulting in inevitable resultant heart failure. TGF-β (transforming growth factor-β)/ALK5 (Activin receptor-like kinase 5)/Smad2/3/4 pathways have been reported to be involved in the process. Recent studies have implicated both activin and its specific downstream component ALK4 in stimulating fibrosis in non-cardiac organs...

Interatrial block (IAB) represents delay or block of conduction between the atria. IAB has been shown to predict the development or recurrence of atrial fibrillation (AF) in various clinical scenarios. Few studies have examined the correlation between coronary artery disease and the prevalence of IAB and its impact on AF. The aim of this study was to determine if specific coronary artery lesions (location and number) are associated with the presence of IAB and development of new-onset AF. Retrospective analysis of patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI) to our institution...

Troponin elevation is required to diagnose acute myocardial infarction (AMI), yet elevated values are often encountered in noncardiac disease states. We evaluated inpatient (IP) and outpatient (OP) encounters at 14 hospitals in calendar year 2014 and found that troponin assays were performed during 12% of all OP visits and 29% of all IP visits: 82,853 encounters in all. We employed an expert panel to estimate the likelihood of AMI based on primary International Statistical Classification of Diseases and Related Health Problems, 9th edition diagnoses...

OBJECTIVE: We sought to assess the early success and safety of catheter-directed, ultrasound-assisted (CDUA) thrombolysis for acute pulmonary embolism (PE) in patients deemed to be "high risk" for thrombolytic therapy. METHODS: A retrospective evaluation of patients who underwent CDUA pulmonary thrombolysis in our practice during 39 months is reported. There were 91 patients considered, all of whom presented with acute PE as diagnosed by computed tomography angiography...

INTRODUCTION: Dyspnea is the symptom most commonly reported by patients with heart failure (HF) and/or pulmonary disease, the obese and the elderly. Recently 'bendopnea' (shortness of breath when bending forward) has been described in patients with HF. OBJECTIVE: To determine the association of exertional dyspnea, orthopnea, paroxysmal nocturnal dyspnea and bendopnea with chronic disease, especially heart failure, and their phenotypes in primary care. METHODS: This cross-sectional study included 633 individuals aged between 45 and 99 years enrolled in a primary care program in Niteroi, Brazil...

Advances in medical and interventional therapy over the last few decades have revolutionized the treatment of acute myocardial infarction. Despite the ability to restore epicardial coronary artery patency promptly through percutaneous coronary intervention, tissue level damage may continue. The reported 30-day mortality after all acute coronary syndromes is 2 to 3%, and around 5% following myocardial infarction. Post-infarct complications such as heart failure continue to be a major contributor to cardiovascular morbidity and mortality...

AIMS: Microvascular obstruction (MVO) is associated with a worse prognosis in patients with ST-elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI). However, data about incidence, clinical outcome and correlates of MVO in latecomers after STEMI are still lacking. METHODS: We prospectively enrolled consecutive patients that were latecomers after STEMI (symptoms onset >12h) undergoing PCI. We performed an angiographic analysis to assess the occurrence of MVO [defined as TIMI flow grade ≤2 or 3 with a myocardial blush grade <2]...

Dysglycemia on admission is known to predict the prognosis of ST-segment elevation myocardial infarction (STEMI). Recently, hypoxic liver injury (HLI) has been proposed as a novel prognosticator for STEMI. We evaluated the prognostic impact of combined dysglycemia and HLI at the time of presentation in patients with STEMI who underwent primary percutaneous coronary intervention. From 2007 to 2014, 1,525 consecutive patients (79% men, mean age 61 years) who underwent primary percutaneous coronary intervention for STEMI in the INTERSTELLAR (Incheon-Bucheon Cohort of Patients Undergoing Primary PCI for Acute ST-Elevation Myocardial Infarction) cohort were analyzed retrospectively...

In this study, we explored the microRNAs responsible for the regulation of PAI-1 during LPS-stimulated inflammation in human aortic endothelial cells, subsequently studied the effect of a newly synthesized mitochondria-targeted esculetin (Mito-Esc) that was shown for its anti-atherosclerotic potential in modulating PAI-1 levels and its targeted miRs during angiotensin-II-induced atherosclerosis in ApoE(-/-) mice. LPS-stimulated PAI-1 was accompanied with an upregulation of miR-19b and down-regulation of miR-30c...

BACKGROUND: A negative sinus P wave in lead V2 (NPV2 ) of the electrocardiogram (ECG) is rare when leads are positioned correctly. This study was undertaken to clarify the significance of an unusually high incidence of this anomaly found in ECGs at my institution. METHODS: One thousand four hundred thirty-five ECGs were randomly selected to determine the incidence and gender frequency in tracings showing positive (PPV2 ), and biphasic (BPV2 ) P waves in V2 , as well as NPV2 ...

So far, systematic reviews have suggested an increased risk of cardiovascular diseases (CVD) in psoriatic patients, though some results have been conflicting. The aim of this study was to update the current level of evidence through a systematic search in MEDLINE, EMBASE and Cochrane Central Register databases. In total, 13 high-quality observational studies estimating the incidence of CVD were included. Patients with mild psoriasis had an increased risk of stroke [Hazard ratio (HR) = 1.10, 95% CI: 1.0-1...

PURPOSE OF REVIEW: Aspirin use before coronary artery bypass graft (CABG) surgery has been a puzzling question for years. Controversy existed regarding the overall benefits vs. risk of pre-operative aspirin use and was translated to conflicting guidelines from major societies. RECENT FINDINGS: Observational studies have suggested a reduced mortality with pre-operative aspirin use. A meta-analysis of randomized controlled trials showed increased risk of post-operative bleeding with aspirin, with no associated increased mortality risk...

OBJECTIVES: Evidence on the safety and long-term efficacy of super selective bronchial artery embolisation (ssBAE) using platinum coils in patients with haemoptysis is insufficient. The objective of the present study was to evaluate the safety and the 3-year postprocedure haemoptysis-free survival rate of de novo elective ssBAE using platinum coils rather than particles for the treatment of haemoptysis. DESIGN: A single-centre retrospective observational study. SETTING: Hemoptysis and Pulmonary Circulation Center in Japan...

The incidence of myocardial infarction (MI) and sudden cardiac death increases with age. Here we describe the development of a minimally invasive large animal model of MI that can be applied to young or aged animals. We demonstrate that rabbit coronary anatomy is highly variable, more so than described in previous literature. In this work we categorize the coronary pattern of 37 young and 63 aged rabbits. Aged rabbits had a higher degree of branching from the left main coronary artery. Standardizing the model across age cohorts required a new approach, targeting an area of myocardium rather than a specific vessel...
