Autonomic dysfunction appears to be prevalent in people living with HIV/AIDS (PLWHA). However, there are limited data on the resting autonomic responses to exercise in active and insufficiently active PLWHA. We aimed to determine whether active PLWHA have better autonomic responses compared with insufficiently active PLWHA. Active PLWHA receiving anti-retroviral therapy (n=13) and insufficiently active PLWHA (n=10) were recruited. A 10-min recording of the supine electrocardiogram was taken. Resting heart rate variability was analyzed from this electrocardiogram...

Extraction of murine cardiac functional parameters on a beat-by-beat basis is limited with the existing imaging modalities due to insufficient three-dimensional temporal resolution. Faster volumetric imaging methods enabling in vivo characterization of functional parameters are poised to advance cardiovascular research and provide a better understanding of the mechanisms underlying cardiac diseases. We present a new approach based on analyzing contrast-enhanced optoacoustic (OA) images acquired at high volumetric frame rate without using cardiac gating or other approaches for motion correction...

Bedros Taslakian, Akhilesh K Sista
Acute pulmonary embolism (PE) is the third most common cause of death among hospitalized patients. Treatment escalation beyond anticoagulation therapy is necessary in patients with cardiogenic shock and may be of benefit in select normotensive patients with right heart strain. Percutaneous catheter-based techniques (catheter-directed mechanical thrombectomy, clot maceration, and/or pharmacologic thrombolysis) as an alternative or adjunct to systemic thrombolysis can rapidly debulk central clot in patients with shock...

Significant tricuspid valve disease affects many patients with left-sided heart disease. Concomitant tricuspid valve surgery for at least moderate tricuspid insufficiency is undertaken far less frequently at the time of left-sided heart surgery. The burden of residual tricuspid disease in high-surgical-risk patients has spawned the evolution of several percutaneous treatment options. A dedicated percutaneously delivered tricuspid Spacer device (FORMA Repair System) has been developed and trialed in humans. This system anchors a Spacer to reduce the regurgitant orifice area, thereby providing a surface for valve leaflet coaptation...

Context: Mineralocorticoid (MC) replacement therapy in patients with primary adrenal insufficiency (PAI) was introduced more than 60 years ago. Still, there are limited data on how MC substitution should be optimized, since MC dosing regimens have only been systematically investigated in a few studies. We review the management of current standard MC replacement therapy in PAI and its plausible impact on outcome. Evidence Acquisition: Using PubMed, we conducted a systematic review of the literature from 1939 to 2017, with the following keywords: 'adrenal insufficiency', 'mineralocorticoid deficiency', 'aldosterone', 'cardiovascular disease', 'hypertension', and 'heart failure'...

Electrogenesis in the heart begins in the sinoatrial node and proceeds down the conduction system to originate the heartbeat. Conduction system disorders lead to slow heart rates that are insufficient to support the circulation, necessitating implantation of electronic pacemakers. The typical electronic pacemaker consists of a subcutaneous generator and battery module attached to one or more endocardial leads. New leadless pacemakers can be implanted directly into the right ventricular apex, providing single-chamber pacing without a subcutaneous generator...

BACKGROUND: Published nomograms of pediatric echocardiographic measurements are limited by insufficient sample size to assess the effects of age, sex, race, and ethnicity. Variable methodologies have resulted in a wide range of Z scores for a single measurement. This multicenter study sought to determine Z scores for common measurements adjusted for body surface area (BSA) and stratified by age, sex, race, and ethnicity. METHODS AND RESULTS: Data collected from healthy nonobese children ≤18 years of age at 19 centers with a normal echocardiogram included age, sex, race, ethnicity, height, weight, echocardiographic images, and measurements performed at the Core Laboratory...

BACKGROUND: Having support from an informal carer is important for heart failure patients. Carers have the potential to improve patient self-care. At the same time, it should be acknowledged that caregiving could affect the carer negatively and cause emotional reactions of burden and stress. Dyadic (patient and informal carer) heart failure self-care interventions seek to improve patient self-care such as adherence to medical treatment, exercise training, symptom monitoring and symptom management when needed...

ETHNOPHARMACOLOGICAL RELEVANCE: Rubia cordifolia is a common traditional Chinese medicine that promotes blood circulation and eliminates blood stasis, and has been used to cure diseases related to blood stasis syndrome (BSS) clinically for many years. It has been previously demonstrated that anti-thrombosis and pro-angiogenesis can improve BSS. However, the anti-thrombotic and pro-angiogenic activities of Rubia cordifolia have not been well investigated. AIM OF STUDY: To determine the potential anti-thrombotic and pro-angiogenic activities of Rubia cordifolia and to elucidate the underlying mechanisms...

OBJECTIVES: The Blalock-Taussig shunt (BTS) operation is a cornerstone as initial palliative surgery for congenital heart disease with severely reduced pulmonary blood flow (PBF). The ideal PBF provided by BTS is crucial for an uneventful postoperative course, since excess PBF results in acute distress of the systemic circulation and insufficient PBF requires another BTS surgery. Therefore, the goal of this study was to develop a simple device to control the shunt graft flow percutaneously using a constrictor balloon connected to a subcutaneous port...

Diabetes mellitus (DM) is a chronic metabolic disorder that requires regular medical care to prevent severe complications. The elevated blood glucose level affects the eyes, blood vessels, nerves, heart, and kidneys after the onset. The affected blood vessels (usually due to atherosclerosis) may lead to insufficient blood circulation particularly in the lower extremities and nerve damage (neuropathy), which can result in serious foot complications. Hence, an early detection and treatment can prevent foot complications such as ulcerations and amputations...

The prevalence of the right heart failure (RHF) is poorly known. However, RHF is often a consequence of left heart failure due to an interdependance between both ventricles. RHF should be indentified because of prognostic relevance. RHF is defined by the inability to maintain adequate cardiac output through the lung circulation. It can result from volume overload, pressure overload, or a disorder of systolic function. Adaptive mechanisms such as dilation or hyper-trophy will maintain adequate hemodynamics. Once these mechanisms become insufficient, congestive signs and hemodynamic consequences will appear...

Tools for clinical assessment and escalation of observation and treatment are insufficiently established in the newborn population. We aimed to provide an overview over early warning- and track and trigger systems for newborn infants and performed a nonsystematic review based on a search in Medline and Cinahl until November 2015. Search terms included 'infant, newborn', 'early warning score', and 'track and trigger'. Experts in the field were contacted for identification of unpublished systems. Outcome measures included reference values for physiological parameters including respiratory rate and heart rate, and ways of quantifying the extent of deviations from the reference...

We present the case of a 58-year-old man who presented to our wound care centre with a 7 -month history of a progressive unilateral leg ulcer. He reported intermittent, heavy bleeding at the ulcer. The duplex sonography showed a bilateral incompetence of the saphenofemoral junctions and the entire course of the great saphenous veins and, surprisingly, also a bilateral reversed arterial-like pulsating flow in the great and small saphenous veins as well as in the deep veins of the lower extremities. During cardiac examination by auscultation and echocardiography, we detected a previously undescribed severe tricuspid insufficiency with strongly reduced systolic ejection of both the left and the right ventricle and repercussions on the peripheral venous system as a cause for the pulsating veins...
