(Press-News.org) Energy drinks may increase blood pressure and disturb your heart's natural rhythm, according to research presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions.
Researchers analyzed data from seven previously published observational and interventional studies to determine how consuming energy drinks might impact heart health.
In the first part of the pooled analysis, the researchers examined the QT interval of 93 people who had just consumed one to three cans of energy drinks. They found that the QT interval was 10 milliseconds longer for those who had consumed the energy drinks. The QT interval describes a segment of the heart's rhythm on an electrocardiogram; when prolonged, it can cause serious irregular heartbeats or sudden cardiac death.
"Doctors are generally concerned if patients experience an additional 30 milliseconds in their QT interval from baseline," said Sachin A. Shah, Pharm.D., lead author and assistant professor at University of the Pacific in Stockton, Calif.
"QT prolongation is associated with life-threatening arrhythmias. The finding that energy drinks could prolong the QT, in light of the reports of sudden cardiac death, warrants further investigation." said Ian Riddock, M.D., a co-author and director of preventive cardiology at the David Grant Medical Center, Travis Air Force Base, Calif.
Researchers also found that the systolic blood pressure, the top number in a blood pressure reading, increased an average of 3.5 points in a pool of 132 participants.
"The correlation between energy drinks and increased systolic blood pressure is convincing and concerning, and more studies are needed to assess the impact on the heart rhythm." Shah said. "Patients with high blood pressures or long QT syndrome should use caution and judgment before consuming an energy drink.
"Since energy drinks also contain caffeine, people who do not normally drink much caffeine might have an exaggerated increase in blood pressure."
The pooled studies included healthy, young patients 18-45 years old. "People with health concerns or those who are older might have more heart-related side effects from energy drinks", said Shah.

Eating too much salt led to 2.3 million heart-related deaths worldwide in 2010
2013-03-22
Eating too much salt contributed to 2.3 million deaths from heart attacks, strokes and other heart-related diseases throughout the world in 2010, representing 15 percent of all deaths due to these causes, according to research presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions.
The researchers analyzed 247 surveys of adult sodium intake, stratified by age, gender, region and country between 1990 and 2010 as part of the 2010 Global Burden of Diseases Study, an international collaborative ...
Most pre-packaged meals, snacks for toddlers contain too much salt
2013-03-22
Nearly 75 percent of commercial pre-packaged meals and savory snacks for toddlers are high in sodium, according to research presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions.
In the first study to look at the sodium content in U.S. baby and toddler foods, researchers compared the sodium content per serving of 1,115 products for babies and toddlers using data on major and private label brands compiled by the U.S. Centers for Disease Control (CDC). Baby food was categorized as intended ...
Poor kidney response to hormone may increase risks for kidney disease patients
2013-03-22
Highlights
Suboptimal kidney response to the hormone FGF-23 may put chronic kidney disease patients at increased risk of premature death and cardiovascular events.
Resistance to the hormonal actions of FGF-23 in the kidney may identify novel aspects of kidney dysfunction.
60 million people globally have chronic kidney disease.
Washington, DC (March 21, 2013) — The kidneys' response to a particular hormone may affect kidney disease patients' heart health and longevity, according to a study appearing in an upcoming issue of the Journal of the American Society ...
Healthy lifestyle linked with longer survival among kidney disease patients
2013-03-22
Highlights
Among individuals with chronic kidney disease, adherence to a healthy lifestyle was associated with a greater likelihood of surviving over a 13-year period.
The greatest survival benefits were related to nonsmoking.
60 million people globally have chronic kidney disease.
Washington, DC (March 21, 2013) — Certain lifestyle factors—such as not smoking, getting regular physical activity, and avoiding a low body weight—may help prolong the lives of individuals with chronic kidney disease (CKD), according to a study appearing in an upcoming issue of the ...
Education for kidney failure patients may improve chances living donor transplantation
2013-03-22
Highlights
In an analysis of 695 patients with kidney failure, Blacks had received less transplant education, were less knowledgeable about transplantation, and were less willing to pursue deceased or living donor transplantation than Whites.
Patients who began a transplant evaluation process with a greater knowledge of transplantation and greater motivation to receive living donor transplants were ultimately more successful at receiving a living donor transplant.
In 2010, a total of 28,662 kidney transplants took place in the U.S. Of those, only 6,809 were from ...

Stem cells use signal orientation to guide division, Stanford study shows
2013-03-22
STANFORD, Calif. — Cells in the body need to be acutely aware of their surroundings. A signal from one direction may cause a cell to react in a very different way than if it had come from another direction. Unfortunately for researchers, such vital directional cues are lost when cells are removed from their natural environment to grow in an artificial broth of nutrients and growth factors.
Now, researchers at the Stanford University School of Medicine and the Howard Hughes Medical Institute have devised a way to mimic in the laboratory the spatially oriented signaling ...
Study: Serious mental illness no barrier to weight loss success
2013-03-22
Through a program that teaches simple nutrition messages and involves both counseling and regular exercise classes, people with serious mental illness can make healthy behavioral changes and achieve significant weight loss, according to new Johns Hopkins research.
These weight loss amounts were similar to those in other successful programs studied with subjects in the general population — studies that specifically excluded people with serious mental illnesses, the researchers say.
Results of the new research, believed to be the first large study of its kind to involve ...

Road traffic pollution as serious as passive smoke in the development of childhood asthma
2013-03-22
New research conducted in 10 European cities has estimated that 14% of chronic childhood asthma is due to exposure to traffic pollution near busy roads.
The results are comparable to the burden associated with passive smoking: the World Health Organization estimates that between 4% and 18% of asthma cases in children are linked to passive smoking.
The findings, published online today (22 March 2013) ahead of print in the European Respiratory Journal, come as the European Commission has declared 2013 the 'Year of Air', which highlights the importance of clean air for ...
