Delaying 2nd Shock After Cardiac Arrest Won't Boost Survival: Study

Posted 7 Apr 2016 by Drugs.com

THURSDAY, April 7, 2016 – Delaying a second shock to the heart in hospital patients with cardiac arrest doesn't improve their chances of survival, suggests a new study that challenges current recommendations. A patient undergoing cardiac arrest needs to be treated with a defibrillator, which sends an electric shock to the heart to restore normal heart rhythm, according to the U.S. National Heart, Lung, and Blood Institute. Guidelines introduced in 2005 recommend delaying a second shock after the first one to allow time for chest compressions. But evidence to support that advice has been lacking, the study authors said. The authors – led by Dr. Steven Bradley of the VA Eastern Colorado Health Care System in Denver – looked at data on the time between first and second defibrillation attempts. The study included more than 2,700 cardiac arrest patients from 172 U.S. hospitals. About 25 ... Read more

Women in Cardiac Arrest May Be Less Likely to Receive Help

Posted 8 Mar 2016 by Drugs.com

TUESDAY, March 8, 2016 – Women are less likely than men to be helped by bystanders if they suffer cardiac arrest, a new study finds. "There is a misconception that women don't have heart problems so they don't get as much help from the public and they are not treated the same by doctors," said study author Dr. Nicole Karam. She is an interventional cardiologist at the European Hospital Georges Pompidou in Paris. Researchers reviewed records of more than 11,400 people who had a cardiac arrest in public areas in and around Paris between 2011 and 2014. Cardiac arrest, the sudden loss of heart function, is often caused by abnormal heart rhythms. It is not the same as a heart attack. Even though bystanders were more likely to be present when women suffered cardiac arrest, researchers found only 60 percent of women received basic life support – such CPR and use of an automated external ...

Many Critically Ill Patients Lack 'Do Not Resuscitate' Orders

Posted 22 Sep 2015 by Drugs.com

TUESDAY, Sept. 22, 2015 – Most people who've survived a cardiac arrest in the hospital don't have "do not resuscitate" (DNR) orders, even if they have a poor prognosis, a new study reports. Fewer than one in four of all cardiac arrest patients had a DNR order prepared within 12 hours of their cardiac arrest, the study found. The numbers were only somewhat higher in patients with the worst prognosis even though their likelihood of recovery was very poor. A cardiac arrest "is a serious and life-altering event that should prompt adequate and informed decisions about prognosis and goals of care," said study lead author Dr. Timothy Fendler, a cardiology fellow at Saint Luke's Mid America Heart Institute in Kansas City, Mo. "These results imply that there could be better alignment between prognosis and decisions that place the patient's wishes, safety and quality of life at the forefront." ... Read more

Blacks at Higher Risk of Sudden Cardiac Arrest Than Whites: Study

Posted 20 Jul 2015 by Drugs.com

MONDAY, July 20, 2015 – Black Americans are more likely than whites to experience sudden cardiac arrest, according to a new study. The study also found that sudden cardiac arrest often occurs at an earlier age in blacks than in whites. Sudden cardiac arrest occurs when the electrical system of the heart malfunctions. This causes the heart to beat erratically or to stop beating. As a result, blood isn't pumped throughout the body. "Sudden cardiac arrest is significantly higher in black Americans compared to whites, at least twofold higher," said study researcher Dr. Sumeet Chugh, associate director of the Cedars-Sinai Heart Institute in Los Angeles. Blacks in the United States tend to have sudden cardiac arrest an average of six years earlier than whites, Chugh said. In his study, he found other major differences as well. "Blacks, in addition to being younger, tended to have more ... Read more

Age No Bar to Aggressive Rx for Cardiogenic Shock

Posted 16 Feb 2009 by Drugs.com

MONDAY, Feb. 16 – Age shouldn't prevent the aggressive treatment of elderly patients with heart attack complicated by cardiogenic shock, Australian researchers report. Cardiogenic shock (CS) occurs when the heart fails to supply enough blood to the body's organs. It is the most common cause of death after heart attack among Americans over the age of 75. There's typically been widespread reluctance to use invasive treatments on elderly heart patients. However, this study found that elderly patients with heart attack complicated by CS who underwent percutaneous coronary intervention (PCI) had a one-year survival rate similar to that of younger patients. "Elderly patients who are admitted to the hospital with massive heart attacks may still benefit from emergency coronary artery balloon angioplasty with stenting, despite their advanced age. Although mortality occurs in roughly half of ... Read more
