Acute myocardial infarction (AMI) is a common disease with serious consequences in mortality and cost. Here we aim to screen the differentially expressed genes (DEGs) as biomarkers for early diagnosis of AMI. The microarray data of AMI was downloaded from Gene Expression Omnibus (GEO), including two independent types of research GSE66360 and GSE62646. The DEGs between control and processed samples were screened out by using limma package. Meanwhile, we performed functional analysis of GO terms and/or KEGG pathways to observe the enriched pathways of the DEGs...

OBJECTIVES: We designed a pilot study to evaluate safety and feasibility of an inexpensive and simple approach to intracoronary hemodilution during primary angioplasty (PPCI) to reduce reperfusion injury. INTRODUCTION: Early revascularization in acute myocardial infarction decreases infarct size and improves outcomes. However, abrupt restoration of coronary flow results in myocardial reperfusion injury and increased final infarct size. Dilution of coronary blood during revascularization may help reduce this damage...

The paper gives an original algorithm for the management of patients with stable coronary artery disease, preserved/moderately reduced left ventricular systolic function, and high-grade ventricular arrhythmias from the first registration of the latter to the choice of treatment policy. Great attention is paid to the assessment of a private clinical case, by determining the nature of arrhythmias, and to the involvement of autonomic regulation in the genesis of ventricular arrhythmias. The importance of topical diagnosis of ventricular arrhythmias and identification of psychological disorders is emphasized...

High-on-treatment platelet reactivity (HPR) is associated with ischemic events in patients on antiplatelet therapy with a history of cardiovascular disease. On the other hand, recent data have associated sepsis with adverse cardiovascular events in patients admitted with bacteremia or respiratory infection. We aimed to assess P2Y12-mediated platelet reactivity (PR) during sepsis and recovery in patients under clopidogrel. This was a prospective observational study. Incoming patients presenting with signs/symptoms of sepsis already on a maintenance dose of clopidogrel of 75 mg qd for cardiovascular events were included in this study...

Personality traits are associated with major adverse coronary events (MACE) in patients with coronary artery disease (CAD). However, the link between personality traits and intravascular morphology in CAD patients is poorly understood. This study investigated the relationship between personality traits, specifically Type A behavior pattern and Type D personality, and plaque vulnerability. After adjustment for demographic and clinical factors, multivariable regression analysis showed no association between Type A and optical coherence tomography indices...

BACKGROUND: Patients with chronic kidney disease (CKD) have worse adverse cardiovascular outcomes after coronary artery bypass grafting (CABG). However, the adverse cardiovascular outcomes between off-pump coronary artery bypass grafting (OPCAB) versus on-pump coronary artery bypass grafting (ONCAB) in these patients have been a subject of debate. METHODS: We undertook a comprehensive literature search of PubMed, Embase, and the Cochrane Library database to identify all relevant studies comparing techniques between OPCAB and ONCAB in CKD patients...

BACKGROUND: Recently, malnutrition has been shown to be related to worse clinical outcomes in patients with heart failure. However, the association between nutritional status and clinical outcomes in patients with coronary artery disease (CAD) remains unclear. We investigated the prognostic value of malnutrition assessed by the Controlling Nutritional Status (CONUT; range 0-12, higher = worse, consisting of serum albumin, cholesterol and lymphocytes) score in patients with CAD. METHODS: The CONUT score was measured on admission in a total of 1987 patients with stable CAD who underwent elective percutaneous coronary intervention (PCI) between 2000 and 2011...

Intraoperative Transit Time Flowmetry is currently recommended to assess graft patency during coronary artery bypass grafting (CABG), especially in presence of haemodynamic instability or inability to wean the patient from cardiopulmonary bypass, new regional wall motion abnormalities, or significant ventricular arrhythmias. The VeriQ™ system is one of the currently available systems, which detects imperfections that may be corrected by graft revision. In this case report, multivessel coronary spasm (CS) post-CABG interferes with these intraoperative parameters misleading initially into false results...

Thrombosis is a frequent cause of morbidity and mortality in patients with nephrotic syndrome (NS). Though venous thromboses are common in NS, arterial thromboses are relatively rare. Commonly involved arteries include coronary, iliac, femoral, renal, cerebral, pulmonary, mesenteric, and axillary arteries, and the aorta. Arterial thromboses are associated with poor prognosis; treatment options are limited and patients may not always be amenable to treatment. We present the case of a 39-year-old female with NS who presented with thigh pain and was found to have sub-acute popliteal artery thrombosis...

Background: Heart Failure (HF) is a progressive epidemic associated with considerable morbidity and mortality. Self-reported data from the National Health and Nutrition Examination Survey (NHANES) provides a unique representation of individuals suffering from HF. The purpose of this study is to analyze updated NHANES 2013-2014 data to identify any changes in the prevalence and current risk factors of HF, especially given the novel lifestyles and increased medical awareness of current generations. Methods: NHANES uses a multistage probability sampling design under the Centers for Disease Control and Prevention (CDC)...

INTRODUCTION: Despite advances in stroke care, readmission rates for patients with ischemic stroke remain high. Although factors such as age, diabetes, and continuous use of antiplatelet agents have been found to predict readmission rates, the impact of after-hospital care has not been examined. METHODS: The present study reviewed the charts of 416 patients with acute ischemic stroke and recorded stroke-related comorbidities, neurology follow-up within 21 days, readmission at 0 to 30 days, readmission at 31 to 90 days, and any reasons for readmission...

There is no previously established method for measuring human hepatic triglyceride lipase (HTGL) concentration in serum. In this study, we developed new monoclonal antibodies (MoAb mouse 9A1, MoAb rat 141A1) that react with both HTGL in serum and in post-heparin plasma (PHP) and established a novel enzyme-linked immunosorbent assay (ELISA) system for measuring serum HTGL as well as PHP-HTGL concentrations. To confirm the specificity of MoAb, we performed an immunoprecipitation -immunoblotting analysis. Both MoAb mouse 9A1and MoAb rat 141 A1 were able to immunoprecipitate not only recombinant HTGL and PHP-HTGL but also serum HTGL, demonstrating that HTGL exists in serum obtained without heparin injection...

BACKGROUND: Post-hoc analyses of clinical trials and population-based studies have shown no difference in mortality between men and women, but often show that men are more likely to receive appropriate ICD therapy. We utilized a population-based registry to investigate the interaction of sex and age and the occurrence of ventricular arrhythmia in an ICD population. METHODS AND RESULTS: A total of 776 consecutive patients receiving an ICD for primary or secondary prevention in a provincial ICD registry were studied...

Apoptosis has been involved in a number of pathological conditions including coronary artery disease (CAD). Caspases (CASP) are important regulators and executioners in both extrinsic and intrinsic apoptotic pathways and play a crucial role in the development and progression of CAD. The aim of the present study is to examine the role of Caspase 8 and 3 polymorphisms in the pathogenesis of CAD. 300 CAD patients and 300 healthy controls were genotyped for polymorphisms in CASP8 (-652 6N del/ins, IVS12-19G>A), CASP3 (rs4647601;G>T) by PCR-RFLP...

OBJECTIVES: The main reason for aortic repair failures is recurrent annular dilatation. The fibrous portion of left ventricular outflow tract dilates. A novel device was designed to tackle this problem. METHODS: The device consists of an internal ring applied at the aortic annulus plus an external flexible band at the level of the aortic root. The internal ring has a semi-rigid portion (40%, placed at ventriculo-arterial junction) and a flexible portion to allow it to conform along the curves of the non-coronary/right coronary leaflet and right coronary/left coronary leaflet commissures...

The treatment of aortic regurgitation (AR) in patients undergoing off-pump coronary artery bypass grafting (CABG) is a difficult problem. Aortic valve repair has become a promising therapy for AR. Various annuloplasty approaches have been used and have gained satisfactory results. Thus we adopted off-pump semicircular annuloplasty to treat concurrent moderate AR in 12 high-risk patients. Early follow-up results showed that this way is simple, safe, and effective.

We present a case of transcatheter valve-in-valve replacement performed because of structural valve deterioration of a subcoronary implanted stentless aortic bioprosthesis. A 23-mm self-expandable transcatheter heart valve (THV) with supraannular seating was chosen. The procedure was performed with the patient under conscious sedation. After anchoring and partial valve deployment, the patient experienced an acute onset of angina. The angiogram showed left main coronary artery obstruction. Prompt resheathing and retrieval of the THV was performed, and the procedure was aborted...

Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly, which mostly occurs in the right or noncoronary sinus of Valsalva. Left sinus of Valsava is infrequent. Unruptured SVAs are usually asymptomatic, and the diagnosis of unruptured SVA is usually accidental. A giant unruptured SVA may compress the coronary artery and cause myocardial infarction. Here, we report a rare case of a 50-year-old patient with unruptured giant left SVA causing occlusion of the left anterior descending coronary artery, which was successfully managed with our apparently unique surgical procedure...
