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

Posted 14 hours ago 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

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. "Think of the device as a wearable, skin-mounted ... Read more

Stress May Take Greatest Toll on Younger Women's Hearts: Study

Posted 24 Aug 2016 by Drugs.com

WEDNESDAY, Aug. 24, 2016 – Stress may be especially hard on the hearts of younger women who have heart disease, new research suggests. Researchers gave nearly 700 men and women with heart disease a mentally stressful public speaking assignment. Then they measured blood flow to the heart. Women aged 50 or younger were nearly four times more likely than men of the same age or older women to have reduced blood flow to the heart, said study leader Dr. Viola Vaccarino. She is chair of epidemiology at Emory University Rollins School of Public Health in Atlanta. Reduced blood flow – known medically as myocardial ischemia – can lead to a heart attack, she noted. "Younger women appear to be more vulnerable [than men and older women] to the effects of stress on their heart," Vaccarino said. Experts have long known that younger women have worse outcomes than men of the same age after a heart ... Read more

Sudden Heart Death More Common in Male Minority Athletes

Posted 29 Jun 2016 by Drugs.com

TUESDAY, June 28, 2016 – It's always surprising and heartbreaking to hear about a young athlete dying suddenly. Now a new study finds that in many of these cases, an underlying heart problem was already present. The researchers found that about one-third of sudden cardiac deaths were caused by the heart condition hypertrophic cardiomyopathy. This condition causes a portion of the heart's wall to grow abnormally thick, which hinders the heart's performance. There are often no symptoms, study authors said. This heart condition is often inherited, according to the American Heart Association. About 40 percent of sudden deaths in males were caused by hypertrophic cardiomyopathy. More than 50 percent of hypertrophic cardiomyopathy occurred in minority males. Just 1 percent of these cases were found in minority females, the study published in The American Journal of Medicine found. "We have ... 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 ...

Women's Heart Attacks Are Different Than Men's, Experts Stress

Posted 26 Jan 2016 by Drugs.com

MONDAY, Jan. 25, 2016 – Heart attacks in women often have different causes and symptoms than those in men, and they're deadlier, too. That's the premise of a scientific statement from the American Heart Association (AHA) that hopes to raise awareness about key differences in heart attack indicators and treatment in women. Women who don't recognize their heart attack symptoms won't seek needed medical care, said Dr. Gregg Fonarow, professor of cardiology at the University of California, Los Angeles. "These delays in care contribute to higher mortality rates experienced by women, particularly younger women," he said. Worldwide, cardiovascular disease is the leading cause of death for women. Since 1984 in the United States, heart attack survival has improved for women. But the heart death rates among women still outpace heart deaths in men, according to the AHA statement. The new ...

Long-Term Smog Exposure May Boost Heart, Lung Disease Deaths

Posted 26 Jan 2016 by Drugs.com

MONDAY, Jan. 25, 2016 – Long-term exposure to ozone air pollution – commonly known as smog – may increase the risk of death from heart and lung diseases, a new study indicates. Researchers reviewed data from a U.S. study that began in 1982 and found that for every additional 10 parts per billion (ppb) in long-term ozone exposure, adults were 12 percent more likely to die from lung disease. In addition, they were 3 percent more likely to die from heart disease, and 2 percent more likely to die from any cause, according to the study. It was published online recently in the American Journal of Respiratory and Critical Care Medicine. Pollution specifically attributed to traffic was linked to a 41 percent increased risk of dying from heart disease with each 10 ppb increase in exposure, the investigators found. "About 130 million people are living in areas that exceed the National Ambient ... Read more

Did Antarctic Explorer Shackleton Have a 'Hole in His Heart'?

Posted 21 Jan 2016 by Drugs.com

THURSDAY, Jan. 21, 2016 – A century ago, British explorer Sir Ernest Shackleton was a key figure in the race to explore Antarctica. Now, two expert physicians believe he may have done so while battling a hidden foe: a congenital heart defect. Shackleton made the first crossing of the mountains and glaciers on the island of South Georgia without any health problems, but suffered repeated bouts of breathlessness and weakness on subsequent Antarctic expeditions. The physical problems that plagued Shackleton have long been a mystery, however. In an attempt to solve it, retired anesthetist Dr. Ian Calder and consultant cardiologist Dr. Jan Till studied documents held at the Scott Polar Research Institute in Cambridge, England. The researchers concluded that Shackleton was born with a hole in his heart – an atrial septal defect. The two experts published their theory online recently in the ... Read more

Race Not Tied to Threat of Second Stroke, Study Finds

Posted 21 Jan 2016 by Drugs.com

WEDNESDAY, Jan. 20, 2016 – Younger black people are three times more likely to have a stroke than their white peers, but they may not be at greater risk for a second stroke, new research suggests. "The interaction between black race and age appears to be remarkably different for the risk of first versus second stroke," said study author George Howard, of the University of Alabama at Birmingham. "There was very little difference in race for the risk of a second stroke," he said in a news release from the American Academy of Neurology. The seven-year study involved almost 30,000 people, including close to 3,000 with a history of stroke. Over the course of the study, about 300 of the people who had a previous stroke suffered another one. Meanwhile, just over 800 of the remaining people had their first stroke during the study period. By the age of 45, the black study participants with no ... Read more

Slow Heart Rate Doesn't Mean Early Death Risk: Study

Posted 19 Jan 2016 by Drugs.com

TUESDAY, Jan. 19, 2016 – People with a slow heart rate don't have an increased risk for heart disease, a new study suggests. A typical heart rate for an adult at rest is 60 to 100 beats a minute, but in some people it's below 50 beats a minute, a condition called bradycardia, the researchers said. Because the heart may not be pumping enough blood throughout the body, this slow heart rate can lead to light-headedness, shortness of breath, fainting or chest pain. However, it hasn't been clear whether a slow pulse increases the risk of heart disease, according to the study authors. "For a large majority of people with a heart rate in the 40s or 50s who have no symptoms, the prognosis is very good," corresponding author Dr. Ajay Dharod, instructor in internal medicine at Wake Forest Baptist Medical Center in Winston-Salem, N.C., said in a center news release. "Our results should be ... 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

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

Many ER Patients With Chest Pain Can Be Sent Home, Study Finds

Posted 18 May 2015 by Drugs.com

MONDAY, May 18, 2015 – While chest pain sends many people to the nearest hospital emergency department, most patients may not need a costly hospital stay as a result, a new study suggests. According to a news release from Ohio State University, chest pain sends more than 7 million Americans to the ER every year and about half of them are then admitted for further observation, testing or treatment. But is the cost and inconvenience of a hospital stay always warranted? The study aimed to "assess whether this population of patients could safely go home and do further outpatient testing within a day or two," lead researcher Dr. Michael Weinstock, a professor of emergency medicine at the university's College of Medicine, said in the news release. His team looked at data from more than 11,000 visits by patients experiencing chest pain to three hospitals in Columbus, Ohio between 2008 and ... Read more

New Guidelines Call for No Heart Tests for Low-Risk Patients

Posted 17 Mar 2015 by Drugs.com

TUESDAY, March 17, 2015 – Many patients who are at low risk for heart problems don't need to have screening tests such as EKGs and stress tests, a national association of primary care physicians recommends. The new guideline jibes with research that has suggested the tests are overused in patients who don't need them. "These tests are very unlikely to be helpful in low-risk patients. They are unlikely to give findings that will change patient management or improve patient outcomes," said Dr. Roger Chou, director of the Pacific Northwest Evidence-based Practice Center at Oregon Health & Science University. He is the lead author of the guidelines that were released Monday by the American College of Physicians. At issue are electrocardiography (EKG or ECG), echocardiography (echo) and myocardial perfusion imaging (nuclear) tests. All of these can be used in "stress tests" that require ... Read more
