INTRODUCTION: Ultrasonographic evaluation of patients in cardiac arrest is currently not protocolised in the advanced cardiac life support (ACLS) algorithm. Potentially reversible causes may be identified using bedside ultrasonography that is ubiquitous in most emergency departments (EDs). This study aimed to evaluate the incidence of sonographically detectable reversible causes of cardiac arrest by incorporating an ultrasonography protocol into the ACLS algorithm. Secondary objectives include rates of survival to hospital admission, hospital discharge, and 30-day mortality...

BACKGROUND: In spite of significant improvements in surgical and anesthetic techniques, acute stress response to surgery remains a main cause of mortality and morbidity in coronary artery bypass graft (CABG) surgery patients. Therefore, doing research to find safe and effective modalities with more cardio protective properties seems necessary. OBJECTIVES: In this study, we sought to determine whether intravenous injection of 600 μg Selenium (Se) prior to surgery would limit stress response measured by blood sugar...

INTRODUCTION: Maximal heart rate (HRmax) is linearly declining with increasing age. Regular exercise training is supposed to partly prevent this decline, whereas sex and habitual physical activity do not. High exercise capacity is associated with a high cardiac output (HR x stroke volume) and high ventilatory requirements. Due to the close cardiorespiratory coupling, we hypothesized that the individual ventilatory response to maximal exercise might be associated with the age-related HRmax...

In the last few years, a number of studies were conducted which aimed at understanding the mechanisms of cardiovascular drug, metabolism, and there is still the need to determine the metabolites of cardiac drugs for the purpose of metabolism control. In this study, we employ a direct combination of electrochemical oxidation and mass spectrometric (EC-MS) identification for monitoring the oxidation pathway of ten cardiovascular drugs (metoprolol, propranolol, propafenone, mexiletine, oxprenolol, pirbuterol, pindolol, cicloprolol, acebutolol and atenolol)...

The effect of acute increases in cardiac contractility on cerebral blood flow (CBF) remains unknown. We hypothesized that the external carotid artery (ECA) downstream vasculature modifies the direct influence of acute increases in heart rate and cardiac function on CBF regulation. Twelve healthy subjects received two infusions of dobutamine (first a low dose; 5 μg/kg/min and then a high dose; 15 μg/kg/min) for 12 min each. Cardiac output, blood flow through the internal carotid artery (ICA) and ECA and echocardiographic measurements were performed during dobutamine infusions...

BACKGROUND: Traditional in-person cardiac rehabilitation has substantial benefits for cardiac patients, which are offset by poor attendance. The rapid increase in social media use in older adults provides an opportunity to reach patients who are eligible for cardiac rehabilitation but unable to attend traditional face-to-face groups. However, there is a paucity of research on cardiac patients' experiences and perspectives on using social media to support their health. OBJECTIVE: The aim of this study was to describe cardiac rehabilitation patients' experiences in using social media in general and their perspective on using social media, particularly Facebook, to support their cardiac health and secondary prevention efforts...

BACKGROUND: The 2015 guidelines for cardiopulmonary resuscitation (CPR) are based on an update of the 2010 guidelines with minor revisions. It is important to assess the 2010 guidelines to ensure their efficacy, which may help promote widespread adoption of the 2015 guidelines. METHODS: We conducted a retrospective observational study in a single center that evaluated patients with in-hospital cardiac arrest (IHCA) between 2006 and 2014. Multivariable logistic regression analysis was used to evaluate associations between independent variables and outcomes...

Carfilzomib is a second-generation proteasome inhibitor that irreversibly inhibits chymotrypsin-like (CT-L) activities of the proteasome, and is indicated for relapsed or refractory multiple myeloma. Cardiotoxicity is a well-established adverse effect of carfilzomib. The extent of cardiac toxicity in the literature spans anywhere from palpitations to cardiac arrest, with the most commonly reported manifestation being new-onset or worsening heart failure. A pre-clinical study of the pharmacokinetics and pharmacodynamics of carfilzomib given via intravenous bolus or 30-minute infusion in rats showed that carfilzomib can strongly induce apoptosis and potently damage cardiac myocytes at clinically relevant concentrations...

INTRODUCTION: Spinal immobilization has been indicated for all blunt trauma patients suspected of having cervical spine injury. However, for traumatic cardiac arrest (TCA) patients, rapid transportation without compromising potentially reversible causes is necessary. Our objective was to investigate the temporal trend of spinal immobilization for TCA patients and to examine the association between spinal immobilization and survival. METHODS: We conducted a retrospective cohort study using the Japan Trauma Data Bank 2004-2015 registry data...

The Pan-African Society of Cardiology roadmap aims to achieve a 25% control of hypertension by the year 2025. Whether this is attainable or not depends largely on the capacity of healthcare providers and policy makers to address the rising prevalence of hypertension and its complications, including heart failure. Task sharing is fundamental in optimising hypertension control. The Clinical Research Education, Networking and Consultancy (CRENC) engaged with the Pan-African Society of Cardiology (PASCAR) and the Cameroon Cardiac Society (SCC) in a joint hypertension and heart failure symposium at the Douala General Hospital in 2016...

BACKGROUND: Recent reports have raised concerns that public reporting of 30-day mortality after cardiac surgery may delay decisions to withdraw life-sustaining therapies for some patients. The authors sought to examine whether timing of mortality after coronary artery bypass graft surgery significantly increases after day 30 in Massachusetts, a state that reports 30-day mortality. The authors used New York as a comparator state, which reports combined 30-day and all in-hospital mortality, irrespective of time since surgery...
