Dispatchers should assertively give cardiopulmonary resuscitation (CPR) instructions to bystanders who suspect someone is in cardiac arrest because the benefits from correctly recommending CPR for someone who needs it greatly outweigh the risks from recommending CPR for someone who does not, researchers said in Circulation: Journal of the American Heart Association. http://www.physorg.com/news180708680.html Medicine & Health Tue, 22 Dec 2009 13:30:01 EST news180708680 When the heart is stopped and restarted, the patient's life may be saved but their brain is often permanently damaged. Therapeutic hypothermia, a treatment in which the patient's body temperature is lowered and maintained several degrees below normal for a period of time, has been shown to mitigate these harmful effects and improve survival in adults. http://www.physorg.com/news179066375.html Medicine & Health Thu, 03 Dec 2009 12:41:44 EST news179066375 The chance of surviving an out-of-hospital cardiac arrest has not improved since the 1950s, according to a report by the University of Michigan Health System. http://www.physorg.com/news178996473.html Medicine & Health Wed, 02 Dec 2009 17:15:03 EST news178996473 People can survive cardiac arrest if they receive only chest compressions during attempts to revive them - as advised by the current American Heart Association guidelines. But they cannot survive without access to oxygen sometime during the resuscitation effort, research suggests. http://www.physorg.com/news178812267.html Medicine & Health Mon, 30 Nov 2009 17:40:02 EST news178812267 Patients with an out-of-hospital cardiac arrest who received intravenous (IV) drug administration during treatment, recommended in life support guidelines, had higher rates of short term survival but no statistically significant improvement in survival to hospital discharge or long-term survival, compared to patients who did not receive IV drug administration, according to a study in the November 25 issue of JAMA. http://www.physorg.com/news178311128.html Medicine & Health Tue, 24 Nov 2009 19:10:01 EST news178311128 A woman who suffers sudden cardiac arrest is significantly less likely than a man to exhibit the decrease in the heart's pumping ability that is widely recognized as a precursor, says a new study in the Nov. 24 Journal of the American College of Cardiology. http://www.physorg.com/news177663733.html Medicine & Health Tue, 17 Nov 2009 07:20:01 EST news177663733 Virginia Commonwealth University Medical Center and the Richmond Ambulance Authority have improved resuscitation and survival rates dramatically for cardiac arrest patients by training and equipping paramedics to begin lowering a patient's body temperature in the field during resuscitation and following up at the hospital with a host of high-tech strategies to improve the odds of survival. http://www.physorg.com/news177604279.html Medicine & Health Mon, 16 Nov 2009 15:10:09 EST news177604279 The chance of surviving a cardiac arrest outside a hospital was found to be twice as high when bystanders performed continuous chest compressions without mouth-to-mouth breathing than when bystanders performed standard CPR. These are the latest findings reported by the Resuscitation Research Group at the University of Arizona Sarver Heart Center and the SHARE Program (Save Hearts in Arizona Research and Education) at the Arizona Department of Health Services. http://www.physorg.com/news177599075.html Medicine & Health Mon, 16 Nov 2009 13:30:03 EST news177599075 Rapidly cooling a person in cardiac arrest may improve their chance of survival without brain damage, according to research presented at the American Heart Association's Scientific Sessions 2009. http://www.physorg.com/news177581748.html Medicine & Health Mon, 16 Nov 2009 08:30:01 EST news177581748 Researchers at St. Michael's Hospital working in conjunction with EMS services, paramedics and fire services across Ontario found that a bystander who attempts cardiopulmonary resuscitation (CPR) can quadruple the survival rate to over 50 per cent. But Dr. Laurie Morrison and the research team at Rescu have found only 30 per cent of bystanders in Toronto are willing to help, one of the lowest rates of bystanders helping others in the developed world. http://www.physorg.com/news176737455.html Medicine & Health Fri, 06 Nov 2009 14:00:01 EST news176737455 A research team at Vanderbilt University has developed an innovative optical system to simultaneously image electrical activity and metabolic properties in the same region of a heart, to study the complex mechanisms that lead to sudden cardiac arrest. Tested in animal models, the system could dramatically advance scientists' understanding of the relationship between metabolic disorders and heart rhythm disturbances in humans that can lead to cardiac arrest and death, and provide a platform for testing new treatments to prevent or stop potentially fatal irregular heartbeats, known as arrhythmias. http://www.physorg.com/news176138251.html Medicine & Health Fri, 30 Oct 2009 16:18:05 EST news176138251 (AP) -- Taser International is advising police agencies across the nation not to shoot its stun guns at a suspect's chest. http://www.physorg.com/news175339749.html Medicine & Health Wed, 21 Oct 2009 11:20:02 EST news175339749 Maximizing the proportion of time spent performing chest compressions during cardiopulmonary resuscitation (CPR) substantially improves survival in patients who suffer cardiac arrest outside a hospital setting, according to a multicenter clinical study that included UT Southwestern Medical Center. http://www.physorg.com/news173420522.html Medicine & Health Tue, 29 Sep 2009 05:40:01 EST news173420522 People mourning the loss of a loved one are six times more likely to suffer cardiac arrest, potential proof that you can indeed die of a broken heart, Australian researchers said Tuesday. http://www.physorg.com/news172231620.html Medicine & Health Tue, 15 Sep 2009 11:30:01 EST news172231620 The chance that a person in cardiac arrest will survive increases when rescuers doing cardiopulmonary resuscitation (CPR) spend more time giving chest compressions, according to a multi-center study reported in Circulation: Journal of the American Heart Association. http://www.physorg.com/news172165967.html Medicine & Health Mon, 14 Sep 2009 17:10:04 EST news172165967 More widespread availability of defibrillators and education of the general public could boost survival rates fourfold amongst athletes suffering cardiac arrest, a study has found. In less than half of cases, a bystander initiated cardiopulmonary reanimation. This is crucial as survival at hospital admission is 4 times higher when CPR is attempted and 10 times greater when an electric shock is delivered. http://www.physorg.com/news171007782.html Medicine & Health Tue, 01 Sep 2009 11:10:05 EST news171007782 A pilot study of a system for harvesting kidneys from non-heart-beating donors where attempts of resuscitation after a witnessed out-of-hospital cardiac arrest have failed (uncontrolled NHBDs) resulted in 21 successful kidney transplants - a 10% increase in the transplantation rate - over 17 months. Researchers writing in BioMed Central's open access journal Critical Care have shown that retrieval from uncontrolled NHBDs may provide a valuable source of organs and could help counter the shortage of kidney grafts in France. http://www.physorg.com/news170659326.html Medicine & Health Fri, 28 Aug 2009 06:40:02 EST news170659326 Arizona researchers have added another piece to the mounting body of evidence that suggests during resuscitation efforts to treat patients in cardiac arrest, "passive ventilation" significantly increases survival rates, compared to the widely practiced "assisted ventilation." http://www.physorg.com/news169300393.html Medicine & Health Wed, 12 Aug 2009 13:10:20 EST news169300393 Cooling unconscious cardiac arrest survivors can increase survival and has a cost effectiveness comparable to other widely accepted treatments in modern health care, researchers report in Circulation: Cardiovascular Quality and Outcomes. http://www.physorg.com/news168624134.html Medicine & Health Tue, 04 Aug 2009 17:02:42 EST news168624134 The appropriate placement of automated external defibrillators (AEDs) is critical to optimize their use in public places, according to two studies published in Circulation: Journal of the American Heart Association. http://www.physorg.com/news167936124.html Medicine & Health Tue, 28 Jul 2009 00:00:01 EST news167936124 such as case volume and academic status -do not appear to predict whether patients with cardiac arrest at that facility are likely to experience delays in receiving defibrillation, according to a report in the July 27 issue of Archives of Internal Medicine. http://www.physorg.com/news167932769.html Medicine & Health Mon, 27 Jul 2009 17:00:10 EST news167932769 Infants and young children treated with heart drugs get the wrong dose or end up on the wrong end of medication errors more often than older children, according to research led by the Johns Hopkins Children's Center to be published July 6 in Pediatrics. http://www.physorg.com/news166206061.html Medicine & Health Tue, 07 Jul 2009 17:21:24 EST news166206061 You don't have to be Michael Jackson to have this problem: The odds of surviving cardiac arrest after getting CPR in a hospital are slim and have not improved in more than a decade, a big Medicare study concludes. http://www.physorg.com/news165689018.html Medicine & Health Wed, 01 Jul 2009 21:50:01 EST news165689018 Local laws, insurance reimbursement and public misperceptions impede emergency medical services (EMS) workers from using best resuscitation practices, according to a study reported in Circulation: Cardiovascular Quality and Outcomes. http://www.physorg.com/news165598553.html Medicine & Health Tue, 30 Jun 2009 20:40:01 EST news165598553 When faced with patients suffering a heart attack, doctors have two choices: inject them with medication to dissolve the blood clot (fibrinolytic therapy) or insert a small balloon to open the blocked artery (primary percutaneous coronary intervention (PCI)). http://www.physorg.com/news165150274.html Medicine & Health Thu, 25 Jun 2009 12:30:01 EST news165150274 In the first large-scale study of its kind, researchers at the University of Michigan's C.S.
