Ischemic heart disease (IHD) is a leading cause of morbidity and mortality in developed countries. Current pharmacological and interventional therapies provide significant improvement in the life quality of patient; however, they are mostly symptom-oriented and not curative. A high disease and economic burden of IHD requires the search for new therapeutic strategies to significantly improve patients' prognosis and quality of life. One of the main challenges during IHD is the massive loss of cardiomyocytes that possess minimal regenerative capacity...

BACKGROUND: The nosological nature of "idiopathic" arrhythmias and the effect of etiotropic and pathogenetic treatment are often unknown. METHODS AND RESULTS: 19 patients (42.6±11.3 years, 9 women) with atrial fibrillation (n = 16), supraventricular (n = 10) and ventricular (n = 4) premature beats, supraventricular (n = 2) and ventricular tachycardia (n = 1), left bundle branch block (n= 2), AV block (n = 2) without structural heart changes. Viruses were identified (polymerase chain reaction, PCR) along with measurement of anti-heart antibodies (AHA) and endomyocardial biopsy (EMB)...

Among heart irregularities, congenital pericardial defect is an unusual anomaly, and is typically left dominant. However, cases of right pericardial defect with heart herniation are extremely rare. This is a case of congenital right pericardial defect with herniation of the right ventricle free wall and right ventricular outflow tract. The patient is asymptomatic and refused further intervention but even indolent discomfort underscores the risks of iatrogenic injuries to the heart and sudden death caused by mechanical pathogenesis due to changes in anatomical positions of the cardiac structures...

BACKGROUND: Mice are frequently used in research to examine outcomes of myocardial infarction (MI) and to investigate therapeutic interventions at an early pre-clinical stage. The MI model is generated by surgically occluding a major coronary artery, but natural variation in murine coronary anatomy can generate variable outcomes that will inevitably affect the accuracy of such investigations. The aim of this study was to use MRI to derive the most sensitive early variable that could be used to predict subsequent adverse cardiac remodelling in a male mouse model of MI...

BACKGROUND: Most studies show that women with symptoms of acute coronary syndrome (ACS) delay seeking care longer than men do. Contributing factors include women being more likely to experience diverse symptoms, to experience symptoms that do not match preexisting symptom expectations, to interpret symptoms as noncardiac, and to minimize symptoms until they become incapacitating. OBJECTIVE: The aim of the study is to identify factors influencing women's ability to recognize and accurately interpret symptoms of suspected ACS...

INTRODUCTION: Acute coronary syndrome (ACS) is one of the leading causes of morbidity and mortality worldwide. Secondary cardiovascular risk reduction therapy (consisting of an aspirin, a β-blocker, an ACE inhibitor or an angiotensin II receptor blocker and a statin) is needed for all patients with ACS. Less than 80% of patients with ACS in Qatar use this combination after discharge. This study is aimed to evaluate the effectiveness of clinical pharmacist-delivered intervention at discharge and tailored follow-up postdischarge on decreasing hospital readmissions, emergency department (ED) visits and mortality among patients with ACS...

BACKGROUND: Auckland City Hospital (ACH) established a Heart Murmur Clinic (HMC) with the aim of providing prompt assessment of patients with asymptomatic systolic murmurs. This may lead to early intervention and improved outcomes if significant structural heart disease is detected and reassurance if no significant findings found. Similar clinics for children have proven beneficial; the benefit of a HMC in an adult population has been difficult to determine. OBJECTIVES: To review the clinical demographics and echocardiographic information of patients presenting to our HMC and to assess what proportion had significant structural heart disease and determine the common structural abnormalities in this population...

Exercise induces arterial flow patterns that promote functional and structural adaptations, improving functional capacity and reducing cardiovascular risk. While heat is produced by exercise, local and whole-body passive heating have recently been shown to generate favorable flow profiles and associated vascular adaptations in the upper limb. Flow responses to acute heating in the lower limbs have not yet been assessed, or directly compared to exercise, and other cardiovascular effects of lower-limb heating have not been fully characterized...

BACKGROUND: A number of registry studies have reported suboptimal adherence to guidelines for cardiovascular prevention during the first year after acute myocardial infarction (AMI). However, only a few studies have addressed long-term secondary prevention after AMI. This study evaluates prevention guideline adherence and outcome of guideline-directed secondary prevention in patients surviving 2 years after AMI. METHODS: Patients aged 18-85 years at the time of their index AMI were consecutively identified from hospital discharge records between July 2010 and December 2011 in Gothenburg, Sweden...

Muscular dystrophies (MDs) are clinically and molecularly a highly heterogeneous group of single-gene disorders that primarily affect striated muscles. Cardiac disease is present in several MDs where it is an important contributor to morbidity and mortality. Careful monitoring of cardiac issues is necessary but current management of cardiac involvement does not effectively protect from disease progression and cardiac failure. There is a critical need to gain new knowledge on the diverse molecular underpinnings of cardiac disease in MDs in order to guide cardiac treatment development and assist in reaching a clearer consensus on cardiac disease management in the clinic...

With increasing utilization of cardiac computed tomographic angiography (CTA) and widespread adoption of fusion imaging technology allowing the merger of pre-procedural CTA with fluoroscopy, the ability of CTA to guide structural heart interventions has evolved significantly. It has opened new possibilities in mitral valve (MV) interventions with improved pre-procedural planning and intra-procedural guidance. Given the lack of fluoroscopic landmarks of the mitral apparatus and continued growth of native MV device technologies, the value of CTA will continue to develop...

Luke J Burchill
Heart failure (HF) in adult congenital heart disease (ACHD) is vastly different to that observed in acquired heart disease. Unlike acquired HF in which pharmacological strategies are the cornerstone for protecting and improving ventricular function, ACHD-related HF relies heavily upon structural and other interventions to achieve these aims. patients with ACHD constitute a small percentage of the total adult heart transplant population (∼3%), although the number of ACHD heart transplant recipients is growing rapidly with a 40% increase over the last two decades...

Mitochondria are the powerhouses of the cell and are involved in essential functions of the cell, including ATP production, intracellular Ca(2+) regulation, reactive oxygen species production & scavenging, regulation of apoptotic cell death and activation of the caspase family of proteases. Mitochondrial dysfunction and oxidative stress are largely involved in aging, cancer, age-related neurodegenerative and metabolic syndrome. In the last decade, tremendous progress has been made in understanding mitochondrial structure, function and their physiology in metabolic syndromes such as diabetes, obesity, stroke and hypertension, and heart disease...

BACKGROUND: Physiological noise is one of the major confounds for fMRI. A common class of correction METHODS: model noise from peripheral measures, such as ECGs or pneumatic belts. However, physiological noise correction has not emerged as a standard preprocessing step for fMRI data yet due to: (1) the varying data quality of physiological recordings, (2) non-standardized peripheral data formats and (3) the lack of full automatization of processing and modeling physiology, required for large-cohort studies...

Pregnant women often complain of palpitations. The differential diagnosis for new-onset palpitations in pregnancy ranges from benign conditions to life-threatening arrhythmias. Maternal arrhythmias can occur in isolation or in the setting of underlying structural heart disease. Optimal management of maternal cardiac arrhythmias includes identification of the specific arrhythmia, diagnosis of comorbid conditions, and appropriate intervention. In general, management of maternal cardiac arrhythmias is similar to that of the general population...

Atrial fibrillation (AF) is the most common arrhythmia worldwide, leading to an extensive public health and economic burden. The increasing incidence and prevalence of AF is due to the advancing age of the population, structural heart disease, hypertension, diabetes, and thyroid disease. The majority of costs associated with AF have been attributed to the cost of hospitalization. In order to minimize costs and decrease hospitalizations, counseling on modifiable risk factors contributing to AF has been strongly emphasized...
