In their paper published in Cell the investigators describe discovering that macrophages are also essential to the healthy functioning of the heart, helping conduct the electric signals that coordinate the heartbeat. https://medicalxpress.com/news/2017-04-macrophages-shown-essential-healthy-heart.html Thu, 20 Apr 2017 12:00:08 EDT news411904563 The presence or absence of the CAP2 gene causes sudden cardiac death in mice, according to new research from the Perelman School of Medicine at the University of Pennsylvania. In particular, the absence of the gene interrupts the animal's ability to send electrical signals to the heart to tell it to contract, a condition called cardiac conduction disease. The study was published in Scientific Reports. https://medicalxpress.com/news/2015-12-heart-gene-sudden-cardiac-death.html Mon, 14 Dec 2015 15:53:36 EST news369330808 Saline solution is a staple of every hospital. No matter the ailment, doctors have known for more than a century that saline is key to keeping patients hydrated and maintaining their blood pressure levels. But the solution could do more, according to Steven Poelzing, an associate professor at the Virginia Tech Carilion Research Institute. https://medicalxpress.com/news/2015-05-personalized-saline-solution-heart-death.html Fri, 29 May 2015 07:20:15 EDT news352102806 (HealthDay)—For patients with symptomatic supraventricular tachycardia (SVT), caffeine is associated with increases in systolic and diastolic blood pressure, but does not impact cardiac conduction or refractoriness, according to a study published in the January issue of the Journal of Cardiovascular Electrophysiology. https://medicalxpress.com/news/2015-01-caffeine-doesnt-affect-cardiac-refractoriness.html Fri, 16 Jan 2015 12:50:01 EST news340633366 In a large population of Medicare beneficiaries with heart failure who underwent implantation of a cardiac resynchronization therapy defibrillator, patients who had the cardiac characteristics of left bundle-branch block and longer QRS duration had the lowest risks of death and all-cause, cardiovascular, and heart failure readmission, according to a study in the August 14 issue of JAMA. https://medicalxpress.com/news/2013-08-heart-failure-patients-benefit-implantation.html Tue, 13 Aug 2013 16:00:01 EDT news295622737 Through a collaborative genome-wide study on individuals, researchers have discovered 14 new genetic variations that are associated with heart rate.

Arrhythmia affects millions of people worldwide. https://medicalxpress.com/news/2011-12-mutation-gene-critical-human-linked.html Tue, 27 Dec 2011 16:40:29 EST news244226422 (Medical Xpress) -- A team of scientists from the Friedrich Miescher Institute for Biomedical Research and the Hebrew University of Jerusalem describe in C. elegans the process leading to a rare form of Emery-Dreifuss muscular dystrophy, a disease caused by a mutation in lamin A in man. Lamin A not only gives shape to the nucleus, but here it is shown that it controls the positioning of genes in the nucleus, thereby guaranteeing proper transcription. In a paper appearing in Current Biology, the authors show that perturbation of tissue-specific gene localization leads to aberrant muscle structure and function. https://medicalxpress.com/news/2011-10-scientists-mechanism-rare-muscle-disease.html Mon, 03 Oct 2011 08:12:05 EDT news236848311 (Medical Xpress) -- Abnormalities in cardiac conduction, the rate at which the heart conducts electrical impulses to contract and relax, are a major cause of death and disability around the world. Researchers at Columbia Engineering School have been developing a new method, Electromechanical Wave Imaging (EWI), that is the first non-invasive technique to map the electrical activation of the heart. Based on ultrasound imaging, EWI will enable doctors to treat arrhythmias more efficiently and more precisely. The study was published online in the May 9th Proceedings of the National Academy of Sciences. https://medicalxpress.com/news/2011-05-method-heart-arrhythmias.html Mon, 09 May 2011 15:57:32 EDT news224175399 An international panel of experts from The Heart Rhythm Society and the European Heart Rhythm Association issued new guideline recommendations for all health care professionals about cardiovascular genetic testing at the Heart Rhythm Society's 32nd Annual Scientific Sessions. https://medicalxpress.com/news/2011-05-guidelines-cardiovascular-genetic.html Fri, 06 May 2011 12:58:38 EDT news223905481
