Shocks From Implanted Defibrillators Trigger Health Costs of Their Own

Posted 12 days ago by Drugs.com

WEDNESDAY, Feb. 15, 2017 – While implanted defibrillators can deliver a potentially lifesaving shock to a heart that's beating erratically, patients often wind up in the emergency room or the hospital needing medical procedures afterwards, a new study shows. That was the case whether the shock was needed or not, and in 38 percent of cases it wasn't, the researchers added. "I see two implications," said study co-author Dr. Matthew Reynolds. "First, we need to do all we can to minimize these shock events, which are known to negatively affect patients' quality of life, are undesirable clinically and, in our study, trigger costly medical interventions." These procedures include invasive measures to test the heart's function, according to the study. "Second, there is no standard approach to managing these events . . . so we need to develop a better understanding of which interventions are ... Read more

Hospitalizations for Common Heart Rhythm Problem on the Rise

Posted 6 Feb 2017 by Drugs.com

MONDAY, Feb. 6, 2017 – U.S. patients with a common heart rhythm disorder called atrial fibrillation (AFib) are ending up in the hospital more often than before, a new study says. The good news is that they're surviving more, too. "The more intensive and costly inpatient care that we're providing for AFib recently is associated with decreasing rates of readmission and both short- and longer-term death rates," study first author Dr. James Freeman said in a Yale University news release. He is an assistant professor of medicine (cardiology) at the school. Freeman noted that use of several newer treatments increased during the study period, including catheter ablation and medications. The use of ablation, which involves burning or freezing specific areas of the heart, rose along with improvements in hospitalizations and death rates. Atrial fibrillation – marked by electrical irregularities ... Read more

'Ablation' Procedure Helps 3 out of 4 Patients With Irregular Heartbeat

Posted 25 Jan 2017 by Drugs.com

WEDNESDAY, Jan. 25, 2017 – Just how successful is the procedure called catheter ablation at fixing irregular heartbeats that can be potentially fatal? Pretty successful, a new study found, but there are caveats. Burning or freezing specific areas of the heart can alleviate the common irregular heart beat called atrial fibrillation in 74 percent of patients. However, the procedure doesn't work for everyone and there are risks of complications, researchers report. Atrial fibrillation increases the risk of early death by two times in women and 1.5 times in men. It causes 20 to 30 percent of all strokes and can decrease quality of life due to palpitations, shortness of breath, tiredness, weakness and psychological distress, the study authors explained. About 2.7 million Americans suffer from atrial fibrillation, according to the American Heart Association. For those whose atrial ... Read more

Could a Therapy for Irregular Heartbeat Harm the Brain?

Posted 24 Jan 2017 by Drugs.com

TUESDAY, Jan. 24, 2017 – Catheter ablation is a common treatment for a form of irregular heartbeat known as premature ventricular contractions. Now, a small new study suggests the approach may put some patients at risk for brain injury. The findings are preliminary, but are "relevant to a large number of patients undergoing this procedure," study senior author Dr. Gregory Marcus said in a news release from the University of California, San Francisco. The study suggests that the procedure may help encourage the formation of brain lesions. Marcus, who directs clinical research at UCSF's department of cardiology, said he hopes the research "will inspire many studies to understand the meaning of and how to mitigate these lesions." The study included 18 patients who underwent catheter ablation for premature ventricular contractions (PVCs) – a type of abnormal heartbeat originating in a ... Read more

Implanted Defibrillators Benefit Seniors: Study

Posted 18 Jan 2017 by Drugs.com

WEDNESDAY, Jan. 18, 2017 – Seniors who receive an implantable cardioverter defibrillator (ICD) have high survival rates, a new study finds. An ICD – which is placed under the skin and connected to the heart with wires – detects an irregular heartbeat and delivers an electrical shock to restore normal rhythm. In the study, researchers analyzed data from more than 12,400 Medicare patients, aged 65 and older, who received an ICD after sudden cardiac arrest or a nearly fatal fast heart rhythm. Nearly 80 percent of the patients survived two years after receiving the implanted device, according to the study published Jan. 16 in the Journal of the American College of Cardiology. More than 65 percent of the patients were hospitalized during the two years after receiving an ICD. Rates ranged from 60.5 percent among those younger than age 70 to 71.5 percent among those 80 and older. About 13 ... Read more

Pregnancy OK for Most Women With Congenital Heart Conditions: Report

Posted 12 Jan 2017 by Drugs.com

THURSDAY, Jan. 12, 2017 – Women with serious congenital heart defects can usually have successful pregnancies – but they should work closely with their doctors before, during and after pregnancy, according to new recommendations from the American Heart Association (AHA). At one time, women born with complex heart conditions were told they could never have a baby, said Dr. Jamil Aboulhosn, a cardiologist and one of the authors of the AHA scientific statement. But that old thinking has evolved, said Aboulhosn, who is based at University of California, Los Angeles Medical Center. Studies in recent years have shown that when those women work with an experienced team of health care providers, they generally can have healthy pregnancies, the statement said. The key is planning, said Mary Canobbio, a registered nurse who led the committee that crafted the new recommendations. "Prepregnancy ... Read more

On Hospital Wards, Patient Crises May Have 'Domino Effect'

Posted 27 Dec 2016 by Drugs.com

TUESDAY, Dec. 27, 2016 – Hospitalized patients have a higher risk of cardiac arrest and transfers to intensive care if they're in wards when other patients have recently suffered similar emergencies, a new study suggests. "This should serve as a wake-up call for hospital-based physicians," study author Dr. Matthew Churpek, an assistant professor of medicine at the University of Chicago, said in a university news release. "After caring for a patient who becomes critically ill on the hospital wards, we should routinely check to see how the other patients on the unit are doing," he said. "Following these high-intensity events, our to-do list should include a thorough assessment of the other patients on the unit, to make sure none of them are at risk of slipping through the cracks," he added. Churpek's team tracked outcomes for adult patients who were admitted to the University of Chicago ... Read more

Heart Rate Change When Standing Up Might Predict Older Adult's Death Risk

Posted 7 Dec 2016 by Drugs.com

WEDNESDAY, Dec. 7, 2016 – Tracking the change in an older adult's heart rate when they stand up might reveal their risk of death over the next several years, a new study suggests. As the researchers explained, when people stand up their heart rate initially increases, and then recovers. The speed of that heart rate recovery in the 20 seconds after standing predicted an older adult's risk of dying within the next four years, according to a team at Trinity College Dublin, in Ireland. "The speed of heart rate recovery in response to standing is an important marker of health and vitality that could be assessed quite readily in a clinical setting such as a hospital," study lead author Dr. Cathal McCrory said in a college news release. One cardiologist in the United States believes the new test has promise. "Changes in heart rate during specific activities is a normal response," said Dr. ... Read more

Lifestyle, Stress May Play Role in Heart Rhythm Disorder

Posted 20 Nov 2016 by Drugs.com

SATURDAY, Nov. 19, 2016 – Stress and poor heart-health habits significantly increase the risk of a common heart rhythm disorder called atrial fibrillation, two preliminary studies suggest. The irregular or quivering heartbeat associated with atrial fibrillation can lead to blood clots, stroke, heart failure and other heart-related complications, the American Heart Association says. One new study included more than 6,500 adults without heart disease. They were rated on seven factors related to heart health: smoking, body mass index, physical activity, diet, total cholesterol, blood pressure and blood sugar. The heart association calls these Life's Simple 7. Compared to those with the worst scores, adults who scored highest were 41 percent less likely to develop atrial fibrillation. Those with average scores were 8 percent less likely to develop the abnormal heartbeat. Although the ... Read more

Hi-Tech Skin Patch Might Someday Track Your Health

Posted 17 Nov 2016 by Drugs.com

THURSDAY, Nov. 17, 2016 – A new type of acoustic sensor that resembles a small Band-Aid on the skin can monitor your heartbeat and other health measures, researchers say. The sensor may one day offer a way to painlessly and wirelessly track an individual's health. The patch, which weighs less than one-hundredth of an ounce, can help doctors monitor heart health, stomach condition, vocal cord activity, lung performance and potentially many other bodily functions, researchers say. "We've developed a soft, skin-like device that can listen to internal sounds created by function of internal organs," explained study co-author John Rogers. He was a professor of materials science and engineering and a professor of chemistry at the University of Illinois at Urbana-Champaign during the study and is currently at Northwestern University.

Trouble Sleeping Tied to Higher Risk for Irregular Heartbeat

Posted 14 Nov 2016 by Drugs.com

MONDAY, Nov. 14, 2016 – There may be yet another reason to try and get a good night's sleep: New research ties poor sleep to a higher odds for a dangerous irregular heartbeat. The condition in question is called atrial fibrillation, a common heart arrhythmia that is strongly tied to an increased risk for clotting and strokes. Now, two studies suggest that trouble getting your Zzzs may raise the risk for atrial fibrillation. One cardiologist who reviewed the studies said the theory may have merit. While neither study could prove cause-and-effect, changes in a person's physiology by a "disturbed sleep cycle may be the mechanism for development and recurrence of atrial fibrillation," said Dr. Jianqing Li. She's a cardiologist at Winthrop-University Hospital in Mineola, N.Y. In one study, a team led by Dr. Gregory Marcus of the University of California, San Francisco, tracked data from ... Read more

No Link Between Caffeine, Irregular Heartbeat in Heart Failure Patient Study

Posted 17 Oct 2016 by Drugs.com

MONDAY, Oct. 17, 2016 – Contrary to common belief, coffee doesn't seem to increase the risk of irregular heartbeats in people with heart failure, according to a small Brazilian study. "Our data reassures that most patients with heart disease might drink moderate doses of caffeine-rich beverages with no major risks," said lead researcher Dr. Luis Rohde. He's from the division of cardiology at the Federal University of Rio Grande do Sul in Porto Alegre. Caffeine-rich beverages have long been suspected of causing several heart-related symptoms, such as palpitations or rapid or irregular heartbeats, Rohde said. "Because of this assumption, counseling to reduce or avoid caffeine consumption is still widely recommended in clinical practice by most physicians for patients with any heart disease," he said. But Rohde's team found no link between caffeine and abnormal heartbeats in the short ... Read more

Smartphone Device Detects Undiagnosed Irregular Heartbeat

Posted 13 Oct 2016 by Drugs.com

THURSDAY, Oct. 13, 2016 – A small device synced to a smartphone may help identify new cases of a potentially deadly, irregular heart rhythm, a preliminary study suggests. Researchers in Hong Kong used this technology to check the feasibility of widespread community screening for atrial fibrillation, a risk factor for stroke. The hope is that catching more cases of this irregular heartbeat (arrhythmia) in the general population will reduce the incidence of stroke. Over 13,000 people participated in the screening. Only 56 of those who were tested had results that couldn't be interpreted. Just over 100 were newly identified as having atrial fibrillation. Among those in the newly identified group, 66 had no symptoms of atrial defibrillation, the investigators found. "Whether this approach is capable of reducing the burden of stroke in our community requires further studies," said Dr. ... Read more

People With Implanted Defibrillators at Higher Car Accident Risk

Posted 29 Aug 2016 by Drugs.com

MONDAY, Aug. 29, 2016 – People who have an implanted cardiac defibrillator (ICD) to control an irregular heartbeat appear to have more car accidents than similarly aged people without such devices, a new Danish study finds. Overall, Danish drivers with ICDs were 51 percent more likely to be involved in a traffic accident over the two-and-a-half years of the study. But the findings aren't necessarily a reason to tighten restrictions on these drivers, since the absolute risk of any one ICD-using driver being involved in an accident remained very low – around 1 percent a year. The issue is a tough one, said study lead author Dr. Jenny Bjerre, a physician at Herlev and Gentofte University Hospital in Copenhagen. "On the one side, as physicians we need to take public road safety into consideration when we assess if these patients are medically fit to drive," she said. "But we also have to ... Read more
