The myocardial infarction, known as heart attack, is the ultimate result of a prolonged/untreated cardiac ischemia. The accurate segmentation of the myocardial infarction or ischemia in images obtained from diversified sources, such as Magnetic Resonance Images or Echocardiograph, is worthwhile for the medical area or the animal experimentation. An alternative image source for ischemia/infarction segmentation is the photo, which can depict the actual heart image. This work presents a method for ischemia segmentation in rat heart photos...

BACKGROUND: Device-detected subclinical atrial fibrillation (AF) refers to infrequent, short-lasting, asymptomatic AF that is detected only with long-term continuous monitoring. Subclinical AF is common and associated with an increased risk of stroke; however, the risk of stroke with subclinical AF is lower than for clinical AF, and very few patients with subclinical AF alone have been included in large AF anticoagulation trials. The net benefit of anticoagulation in patients with subclinical AF is unknown...

We conducted a post hoc analysis of blood pressure (BP) data from long-term antihypertensive trials to identify predictors of visit-to-visit BP variability (BPV). BPV was defined as the within-subject coefficient of variation in systolic BP from week 12 onward. BP data from the Anglo-Scandinavian Cardiac Outcomes Trial-Blood Pressure Lowering Arm, Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial, Comparison of Amlodipine Versus Enalapril to Limit Occurrences of Thrombosis, NY92011, and R-0510 trials were pooled and dichotomized into top 25th and bottom 75th percentiles because of positive skew...

Vasundhara Kain, Ganesh V Halade
Diabetic cardiomyopathy (DCM) or diabetes-induced cardiac dysfunction is a direct consequence of uncontrolled metabolic syndrome and is widespread in US population and worldwide. Despite of the heterogeneous and distinct features of DCM, the clinical relevance of DCM is now becoming established. DCM progresses to pathological cardiac remodeling with the higher risk of heart attack and subsequent heart failure in diabetic patients. In this review, we emphasize lipid substrate quality and the phenotypic, metabolic, and biochemical stressors of DCM in the rodent and human pathophysiology...

Cardiovascular diseases are the leading cause of death of death in Taiwan. Atherosclerosis can lead to serious problems, including heart attack, stroke, or even death. Coronary heart disease (CHD) occurs when plaque builds up in the coronary arteries to cause the ischemic heart disease which will enhance myocardial remodeling and also induce myocardial hypoxia. High density lipoprotein (HDL) has been proposed to have cardio-protective effects. Under hypoxic conditions (1%O2 for 24hr), in H9c2 cells, reactive oxygen species (ROS) is induced which leads to cardiomyocyte apoptosis and cardiac dysfunction...

BACKGROUND: Atrial fibrillation (AF) is the most common supraventricular tachyarrhythmia. The percutaneous left atrial appendage occlusion (LAAO) may be considered for the stroke prophylaxis in patients with nonvalvular AF (NVAF), especially in contraindications for oral anticoagulants (OAC) or high risk of bleeding. The data about implantation, safety, efficacy and follow-up are limited. Moreover, there are no studies on patients with NVAF and heart failure with severe left ventricular systolic dysfunction (left ventricular ejection fraction - LVEF ≤ 35%)...

BACKGROUND AND AIMS: Carotid plaque size and the mean common carotid intima-media thickness measured in plaque-free areas (PF CC-IMTmean) have been identified as predictors of vascular events (VEs), but their complementarity in risk prediction and stratification is still unresolved. The aim of this study was to evaluate the independence of carotid plaque thickness and PF CC-IMTmean in cardiovascular risk prediction and risk stratification. METHODS: The IMPROVE-study is a European cohort (n = 3703), where the thickness of the largest plaque detected in the whole carotid tree was indexed as cIMTmax...

History of major gastrointestinal (GI) bleeding may represent a frequent clinical indication for left atrial appendage occlusion (LAAO) in patients with non-valvular atrial fibrillation (AF). This study aims to investigate the procedural safety and long-term outcome of patients with previous major GI bleeding (MGIB) who underwent LAAO. Data from the Amplatzer Cardiac Plug multicenter registry on 1,047 patients were analyzed. Patients with previous MGIB as indication for LAAO were compared with patients without previous MGIB...

REVIEW
Lina Zhao, Takerra Johnson, Dong Liu
Ischemic diseases, the leading cause of disability and death, are caused by the stenosis or obstruction of arterioles/capillaries that is not compensated for by vessel dilatation or collateral circulation. Angiogenesis is a complex process leading to new blood vessel formation and is triggered by ischemic conditions. Adequate angiogenesis, as a compensatory mechanism in response to ischemia, may increase oxygen and nutrient supplies to tissues and protect their function. Therapeutic angiogenesis has been the most promising therapy for treating ischemic diseases...

BACKGROUND: We previously reported that adult female, but not male rats that were prenatally exposed to methamphetamine exhibit myocardial hypersensitivity to ischemic injury. However, it is unknown whether hypersensitivity to ischemic injury develops when rats are exposed to methamphetamine during adulthood. The goal of this study was to determine whether methamphetamine exposure during adulthood sensitizes the heart to ischemic injury. METHODS: Adult male and female rats received daily injections of methamphetamine (5 mg/kg) or saline for 10 days...

Acute myocardial infarction (heart attack) is the fifth leading cause of death in the United States (Dariush et al., Circulation, 2015, 131, e29-e322). This highlights the need for early, rapid, and sensitive detection of its occurrence and severity through assaying cardiac biomarkers in human fluids. Herein we report chip-based fabrication of the first label-free, nanoplasmonic biosensor to assay cardiac troponin T (cTnT) in human biofluids (plasma, serum, and urine) with high specificity. The sensing mechanism is based on the adsorption model that measures the localized surface plasmon resonance (LSPR) wavelength shift of anti-cTnT functionalized gold triangular nanoprisms (Au TNPs) induced by a change of their local dielectric environment upon binding of cTnT...

R Campbell
Since its introduction in the 1960s as a treatment to restart the heart after sudden cardiac arrest from a heart attack, attempts at cardiopulmonary resuscitation have become more common in other clinical situations. Cardiopulmonary resuscitation can be a lifesaving treatment, with the likelihood of recovery varying greatly depending on individual circumstances; however, overall, the proportion of people who survive following cardiopulmonary resuscitation is relatively low. Anticipatory decisions were recognised as being the best way of ensuring that cardiopulmonary resuscitation was not attempted against individuals' wishes...

BACKGROUND: Cellular therapy of human embryonic stem cell-derived cardiomyocytes (hES-CMs) holds great promise for regenerating infarcted cardiac tissues. Yet, the major challenge remains as little cells survived after grafting. In this study, we examined whether treating hES-CMs with 7, 8, 3'-Trihydroxyflavone (THF) may improve hES-CMs developments both in vitro and in vivo. METHOD: HES-CMs were differentiated in vitro, and treated with 5 μ59M THF for 24 h...
