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

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 ...

New Advisory Says Some Athletes With Heart Conditions OK to Play

Posted 2 Nov 2015 by Drugs.com

MONDAY, Nov. 2, 2015 – Some people with a potentially deadly type of irregular heartbeat may be able to play competitive sports, new guidelines say. The scientific statement from the American Heart Association and the American College of Cardiology pointed out that recent research indicates the risk of sudden cardiac arrest is lower than previously thought for some athletes with irregular heartbeat caused by long QT syndrome and athletes with long QT syndrome who have implanted pacemakers or defibrillators. People with long QT syndrome can experience fast and chaotic heartbeats that can be life-threatening. The new statement applies only to athletes with long QT syndrome who play competitive sports directed by a coach, including baseball, football and basketball. It doesn't apply to people who occasionally play sports for exercise or fun. Since every patient is different, people with ... 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

Test Endurance Athletes for Heart Woes While They Exercise: Study

Posted 3 Jun 2015 by Drugs.com

WEDNESDAY, June 3, 2015 – Endurance athletes should be tested for potentially deadly heart rhythm problems when they are exercising rather than resting, and the tests should include the right ventricle as well as the left ventricle, a new study says. Some athletes who participate in endurance events such as marathons and triathlons may have heart rhythm disorders (arrhythmias) that can cause sudden death. A team of researchers from Australia and Belgium found that important signs of rhythm problems in the heart's right ventricle can only be detected during exercise, according to the study published June 3 in the European Heart Journal. Currently, most routine assessments of athletes with suspected heart rhythm problems are done when the patients are resting, and the focus is on the left ventricle, the investigators said. "You do not test a racing car while it is sitting in the garage. ... Read more
