Hi-Tech Skin Patch Might Someday Track Your Health

Posted 15 days ago 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. "Think of the device as a wearable, skin-mounted ... 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

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

Too Many Public Defibrillators Out of Reach When Needed

Posted 15 Aug 2016 by Drugs.com

MONDAY, Aug. 15, 2016 – Automated external defibrillators (AEDs) placed in public spaces can save the lives of people in cardiac arrest. However, a new Canadian study finds too many of the devices are in buildings that aren't always open, so bystanders can't get them when needed. The study, "serves as a vivid reminder that 24/7/365 access to AEDs is as important as their widespread placement," said one specialist who reviewed the findings, Dr. Howard Levite. He directs cardiology at Staten Island University Hospital in New York City. More AEDs in public spaces, along with timely access, is imperative, he said, because "the potential to improve survival in cardiac arrest is an opportunity that cannot be ignored." Cardiac arrest differs from a heart attack, and occurs when the heart abruptly stops beating. According to the American College of Cardiology (ACC), over 400,000 cases of ... Read more

CPR Help as Near as Your Phone

Posted 4 May 2016 by Drugs.com

WEDNESDAY, May 4, 2016 – A stranger or someone you love suddenly collapses with cardiac arrest, but you don't know CPR. New research shows that help – and CPR instruction – may be just a cellphone call away. This is "a real-world approach that the majority of communities can adopt to help improve survival in out-of-hospital cardiac arrest," said one expert, emergency room physician Dr. Robert Glatter. The new study was led by Dr. Bentley Bobrow of the Arizona Department of Health Services in Phoenix. His team noted that fewer than half of Americans who suffer cardiac arrest in public places receive CPR – cardiopulmonary resuscitation – from bystanders, and survival rates are very low. When cardiac arrest strikes, "time is cardiac muscle," said Glatter, of Lenox Hill Hospital in New York City. "The sooner we can initiate effective chest compressions and defibrillation ... the better ... Read more

Study Ties Implanted Defibrillators to Long-Term Complications

Posted 3 May 2016 by Drugs.com

MONDAY, May 2, 2016 – Implantable defibrillators – devices that detect and correct an abnormal heart rhythm – are associated with a high risk of long-term complications, a new study suggests. "An [implantable cardioverter-defibrillator] is a highly effective treatment option to reduce the risk of sudden cardiac death," said lead researcher Dr. Isuru Ranasinghe, a senior cardiologist at the University of Adelaide in South Australia. "However, there is a substantial and persistent risk of device-related complications and re-operations in the years after implantation." These complications include device malfunction, infection and inflammation, the study authors said. Ranasinghe said the rate of complications is higher than previously reported. "The continued occurrence of complications long after the initial implantation indicates the need for vigilance and ongoing surveillance of ... Read more

Death of Loved One May Trigger Heart Rhythm Trouble

Posted 6 Apr 2016 by Drugs.com

WEDNESDAY, April 6, 2016 – Losing your nearest and dearest may break your heart, literally. People are more likely to develop an irregular heartbeat following the death of their spouse or life partner, particularly if they're younger or the loved one died unexpectedly, a new study suggests. Risk of atrial fibrillation – a quivering or irregular heartbeat that can cause stroke and heart disease – was 41 percent higher among people mourning the death of their partner, compared to others who are not grieving, Danish researchers report. The study reinforces earlier research that has suggested a link between heart rhythm problems and emotional turmoil, said Dr. Mark Estes, director of the New England Cardiac Arrhythmia Center at Tufts Medical Center, in Boston. "Many patients describe that their atrial fibrillation gets worse at a time of emotional stress," Estes said. "This really ... Read more

Wearable 'Defibrillator-in-a-Vest' May Help Some Heart Patients

Posted 29 Mar 2016 by Drugs.com

MONDAY, March 28, 2016 – A vest containing a defibrillator may be an option for some heart patients who can't use an implantable defibrillator – the device that can shock the heart back to a proper rhythm if needed. That's the conclusion of the first science advisory on the devices just issued by the American Heart Association. The advisory, however, cautioned that there are still big gaps in knowledge about the devices and they should only be used as a short-term option for specific patients. "They serve an important niche, but there is relatively limited evidence about their effectiveness and safety," said the advisory's lead author, Dr. Jonathan Piccini, an associate professor of medicine at Duke University Medical Center in Durham, N.C. "We need research and clinical trials to figure out which patient populations they should be applied to and what the relative benefit is," he ... Read more

Spare Dying Patients Electric Shocks From Heart Device, Docs Say

Posted 24 Mar 2016 by Drugs.com

THURSDAY, March 24, 2016 – Dying patients with an implantable heart defibrillator don't know the device can be turned off so that it doesn't give them painful shocks during their last days of life, researchers report. Implantable cardioverter defibrillators (ICDs) are surgically implanted in people with certain heart conditions. They deliver a shock to restore normal heart rhythm when they detect a potentially deadly abnormal rhythm. Doctors are encouraged to inform patients with an implantable cardioverter defibrillator about the benefits of deactivating the device when they are near death. But research shows that up to 31 percent of people with an ICD receive shocks in their final days. Two new studies provide further proof that many doctors aren't following the Heart Rhythm Society and European Society of Cardiology recommendations. A Spanish study of 243 patients with implantable ... Read more

Daily Caffeine Doesn't Seem to Jolt the Heart: Study

Posted 26 Jan 2016 by Drugs.com

TUESDAY, Jan. 26, 2016 – There may be good news for coffee, tea and chocolate lovers: Regular caffeine consumption may not cause dangerous racing of the heart, a new study finds. The finding challenges current medical thinking, the study authors said. However, the health risks of heavy caffeine consumption requires additional research, the researchers added. "Clinical recommendations advising against the regular consumption of caffeinated products to prevent disturbances of the heart's cardiac rhythm should be reconsidered, as we may unnecessarily be discouraging consumption of items like chocolate, coffee and tea that might actually have cardiovascular benefits," said study senior author Dr. Gregory Marcus. He is director of clinical research in the division of cardiology at the University of California, San Francisco (UCSF). "Given our recent work demonstrating that extra heartbeats ... Read more

High 'Resting' Heart Rate Tied to Higher Odds of Early Death

Posted 23 Nov 2015 by Drugs.com

MONDAY, Nov. 23, 2015 – A rapid "resting" heartbeat might mean you have a higher risk of dying early, researchers suggest. "Higher resting heart rate is an independent predictor of all-cause and cardiovascular death," said lead researcher Dr. Dongfeng Zhang, of the department of epidemiology at the Medical College of Qingdao University in Shandong, China. Your resting heart rate, or pulse, is the number of times your heart beats a minute. When you're seated or lying down and relaxed, a normal heart rate is between 60 and 100 beats a minute, according to the American Heart Association. Zhang's team analyzed 46 studies involving more than 2 million patients in all. Compared to people with the lowest resting heart rate, those with a resting heart rate of more than 80 beats a minute had a 45 percent greater risk of death from any cause, while people with a resting heart rate of 60 to 80 ...

Bystander CPR Helps Some Kids Survive Cardiac Arrest

Posted 10 Nov 2015 by Drugs.com

TUESDAY, Nov. 10, 2015 – More American children who suffer cardiac arrest at home or in public places are getting CPR from bystanders, a new study finds. Kids who receive bystander CPR have better survival rates, the researchers said. But, the study didn't find an impact on infant survival rates. "This lack of impact on infants suggests the need for a public health strategy to improve the use of bystander CPR," study lead author Dr. Maryam Naim said in an American Heart Association news release. Naim is an assistant professor of anesthesiology and critical care at the Children's Hospital of Philadelphia at the University of Pennsylvania. Cardiac arrest is the sudden loss of heart function in someone who may or may not have diagnosed heart disease. Each year, more than 420,000 emergency medical services-assessed out-of-hospital cardiac arrests occur in the United States, according to ... Read more

Can Smartphones Interfere With Pacemakers?

Posted 22 Jun 2015 by Drugs.com

MONDAY, June 22, 2015 – Another study suggests that smartphones should be kept a safe distance from implanted cardiac devices like pacemakers and defibrillators, in the rare chance that signaling "interference" occurs. "Nearly everyone uses smartphones and there is the possibility of interference with a cardiac device if you come too close," study senior author Christof Kolb, prior head of electrophysiology at the German Heart Centre, said in a news release from the European Society of Cardiology (ESC). This doesn't mean that people with implanted cardiac devices need to toss their phones away, however. "Patients with a cardiac device can use a smartphone," Kolb said. "But they should not place it directly over the cardiac device. That means not storing it in a pocket above the cardiac device. They should also hold their smartphone to the ear opposite to the side of the device ... Read more
