PURPOSE: Palmar hyperhidrosis (PH) is excessive sweating of the palms resulting from sympathetic overactivity, and patients who undergo endoscopic thoracic sympathectomy (ETS) show reduced cardiac demand after 1 year and improved cerebral perfusion within 2-4 weeks. However, the long-term risks of major adverse cardiovascular events (MACE) following ETS remain unclear. METHODS: We searched the Longitudinal National Health Insurance Database in Taiwan and identified PH patients (International Classification of Disease, Ninth Revision, Clinical Modification diagnostic code 708...

The popularization of genome-wide analyses and RNA sequencing led to the discovery that a large part of the human genome, while effectively transcribed, does not encode proteins. Long non-coding RNAs have emerged as critical regulators of gene expression in both normal and disease states. Studies of long non-coding RNAs expressed in the heart, in combination with gene association studies, revealed that these molecules are regulated during cardiovascular development and disease. Some long non-coding RNAs have been functionally implicated in cardiac pathophysiology and constitute potential therapeutic targets...

Loss of functional cardiomyocytes is a major underlying mechanism for myocardial remodeling and heart diseases, due to the limited regenerative capacity of adult myocardium. Apoptosis, programmed necrosis, and autophagy contribute to loss of cardiac myocytes that control the balance of cardiac cell death and cell survival through multiple intricate signaling pathways. In recent years, non-coding RNAs (ncRNAs) have received much attention to uncover their roles in cell death of cardiovascular diseases, such as myocardial infarction, cardiac hypertrophy, and heart failure...

BACKGROUND: The MADS-box transcription factor myocyte enhancer factor 2C (MEF2C) is required for the cardiac development and postnatal adaptation and in mice-targeted disruption of the MEF2C gene results in dilated cardiomyopathy (DCM). However, in humans, the association of MEF2C variation with DCM remains to be investigated. METHODS: The coding regions and splicing boundaries of the MEF2C gene were sequenced in 172 unrelated patients with idiopathic DCM. The available close relatives of the index patient harboring an identified MEF2C mutation and 300 unrelated, ethnically matched healthy individuals used as controls were genotyped for MEF2C...

OBJECTIVE: Reducing time to reperfusion for ST-segment elevation myocardial infarction (STEMI) is essential in improving outcomes. Consequently, numerous strategies have been employed to reduce median door-to-balloon time (DTBT). METHODS: CODE STEMI is an ED physician-activated STEMI notification system. On activation, an announcement is made over the hospital's public announcement (PA) system. We prospectively analysed all in-hours STEMI patients who had primary percutaneous coronary intervention (PPCI) Pre-CODE STEMI (2014) and after CODE STEMI was implemented (2015)...

BACKGROUND: Cardiovascular diseases are the world's leading cause of mortality. These diseases are rooted in an unhealthy lifestyle. In order to confront this subject, it is essential to identify several risk factors that contribute to heart disease (HD) in people with different attitudes, values, beliefs, expectations and motivations. This study was therefore an attempt to explain the adaptive experiences of children whose parents were involved in myocardial infarction since they were more likely subjected to get the so-called disease...

MicroRNAs (miRNAs) are a class of endogenous, short single-stranded non-coding RNAs, which are tightly linked to cardiac disorders such as myocardial ischemia/reperfusion (I/R) injury. MiR-34a is known to be involved in the hypoxia-induced cardiomyocytes apoptosis. However, the molecular mechanisms are unclear. In this study, we demonstrate under low glucose supply, rat cardiomyocytes are susceptive to hypoxia. Under short time hypoxia, cellular glucose uptake and lactate product are induced but under long time hypoxia, the cellular glucose metabolism are suppressed...

BACKGROUND: Among patients undergoing non-cardiac surgery, major vascular surgery is associated with a high risk of perioperative myocardial infarction (MI). Currently there are no perioperative MI risk calculators accounting for intraoperative and postoperative risk factors in vascular surgery patients. We aimed to investigate specific risk factors for perioperative MI after major open vascular surgery to determine which patients are at highest risk of MI, and the association of perioperative MI with perioperative transfusion...

BACKGROUND: Rapid reperfusion with percutaneous coronary intervention (PCI) is vital for patients with ST segment elevation myocardial infarction (STEMI). However, the guideline-recommended time targets are regularly exceeded. The goal of this study was to gain insight into how Dutch PCI centres try to achieve these time targets by comparing their care processes with one another and with the European guideline-recommended process. In addition, accelerating factors perceived by care providers were identified...

BACKGROUND: Rivaroxaban is an oral anticoagulant approved in the US for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF). We determined the effectiveness and associated risks of rivaroxaban versus other oral anticoagulants in a large real-world population. METHODS: We selected NVAF patients initiating oral anticoagulant use in 2010-2014 enrolled in MarketScan databases. Rivaroxaban users were matched with warfarin and dabigatran users by age, sex, enrolment date, anticoagulant initiation date, and high-dimensional propensity score...

miRNAs are small non-coding endogenous RNAs, typically 21-23 nucleotides long, that regulate gene expression, usually post-transcriptionally by binding to the 3'-UTR of target mRNA, thus blocking translation. The expression of several miRNAs is significantly altered during cardiac hypertrophy, myocardial ischemia, fibrosis, heart failure and other cardiac myopathies. Recent studies have implicated miR-9 in myocardial hypertrophy. However a detailed mechanism remains obscure. In this study, we have addressed the roles of miR-9 in muscle development and function using the genetically tractable model system, the indirect flight muscles (IFMs) of Drosophila melanogaster Bioinformatics analysis identified 135 potential miR-9a targets, of which 27 genes were associated with Drosophila muscle development...

The development of contrast-enhanced ultrasound (CEUS) imaging offers great opportunities for new ultrasound clinical applications such as myocardial perfusion imaging and abdominal lesion characterization. In CEUS imaging, the contrast agents (i.e., microbubbles) are utilized to improve the contrast between blood and tissue based on their high nonlinearity under low ultrasound pressure. In this paper, we propose a new CEUS pulse sequence by combining Hadamard-encoded multi-pulses (HEM) with fundamental frequency bandpass filter (i...

BACKGROUND: Aortic valve replacement is a high-risk surgery (3%-5%, 30-day mortality) performed on approximately 30,000 elderly patients a year in the United States. Currently, preoperative risk assessment is based on a composite of medical examination and a subjective evaluation for frailty ("eyeball test"). Objective frailty assessment using validated indices has the potential to improve risk stratification. The purpose of this study was to (1) establish whether frailty can predict 30-day mortality and composite morbidity in patients undergoing aortic valve replacement and (2) compare the predictive ability of 3 frailty indices in this population...

BACKGROUND: Inflammation in the tumour microenvironment mediated by interleukin 1β is hypothesised to have a major role in cancer invasiveness, progression, and metastases. We did an additional analysis in the Canakinumab Anti-inflammatory Thrombosis Outcomes Study (CANTOS), a randomised trial of the role of interleukin-1β inhibition in atherosclerosis, with the aim of establishing whether inhibition of a major product of the Nod-like receptor protein 3 (NLRP3) inflammasome with canakinumab might alter cancer incidence...

Patients hospitalized for noncardiac conditions often experience increased levels of stress and hemodynamic challenges, making them susceptible to acute coronary events. The clinical features, management strategy, and outcomes of inpatient non-ST segment elevation myocardial infarction (NSTEMI) have not been described. This single-center retrospective study identified patients with inpatient NSTEMI from the University of North Carolina Hospitals discharge database in February 2008 to April 2014 using International Classification of Diseases, Ninth Revision (ICD-9) codes...

The myocardial infarction associated transcript (MIAT), a long non-coding RNA (lncRNA), was originally identified as a candidate gene for myocardial infarction, and was recently shown to participate in the progression of cancer and the process of metastasis. However, the biological role of MIAT and the underlying mechanisms that mediate its role in non-small-cell lung cancer (NSCLC) remain unclear. Here, we have shown that the expression of MIAT in NSCLC tissues was upregulated. Knockdown of MIAT substantially inhibited the invasive ability of NSCLC cells...
