Majority of Youth C. Difficile Infections Linked to Doctor Visits
Antibiotics prescribed in a doctor’s office for other conditions are associated with the majority of Clostridium difficile infections, according to a new study in the journal Pediatrics. Researchers from the U.S. Centers for Disease Control and Prevention (CDC) determined that 71 percent of the cases for youth ages 1-17 were linked to the visits, rather than to overnight stays in health care facilities; two-thirds of adult cases are linked to hospital stays. The findings raise the profile of ongoing efforts to reduce unnecessary prescriptions. “Improved antibiotic prescribing is critical to protect the health of our nation’s children,” said CDC Director Tom Frieden, MD, MPH. “When antibiotics are prescribed incorrectly, our children are needlessly put at risk for health problems including C. difficile infection and dangerous antibiotic resistant infections.” Read more on prescription drugs.
Study: Even Slightly Elevated Blood Pressure Can Do Cardiovascular Damage Over Time
Even slightly elevated blood pressure that does not rise to the clinical definition of hypertension can do cardiovascular damage over time, according to a new study in the Journal of the American Medical Association. Researchers at the University of Oklahoma Health Sciences Center analyzed blood pressure data on more than 4,600 participants, all of whom had their readings tracked over 25 years from young adulthood to middle age. They placed the participants in five blood pressure trajectory categories:
- Low-stable: blood pressure that starts low and stays low
- Moderate-stable: blood pressure that begins only slightly elevated and stays that way
- Moderate-increasing: blood pressure begins only slightly elevated and increases over time
- Elevated-stable: blood pressure that starts at elevated levels, but does not increase
- Elevated-increasing: blood pressure that begins elevated and increases over time
The study determined that participants in the moderate-stable group were 44 percent more likely to have coronary artery calcification than those in the low-stable group. Read more on heart health.
Study: Men Die Earlier in More Patriarchal Societies
Gender differences when it comes to mortality rates are higher in more patriarchal societies, meaning women’s rights are good for men’s health, according to a new study in the American Psychological Association’s Evolutionary Behavioral Sciences. Utilized sociodemographic and mortality data from the World Health Organization, researchers from the University of Michigan (UM) School of Public Health found that men living in the top 25 percent most-patriarchal societies were 31 percent more likely to die than men in the least patriarchal quartile, compared to mortality rates for women. Researchers noted that the study only included societies with infrastructures capable of providing reliable data, so the difference could be even more pronounced. Possible explanations include:
- Males in societies where they are more socially dominant tend to engage in riskier behaviors that can lead to death.
- These societies tend to have more resources and social status concentrated in a smaller group of elite men, and men with greater control of resources and social status historically have had more reproductive success.
- In their quest for social dominance, men will go up against other men to gain power and engage in forms of competitive, and sometimes dangerous, behavior.
"Gender inequality is inherently related to inequality in general, and this is bad for both men and women's health, though especially harmful to men in increasing the risk of death," said UM researcher Daniel Kruger. Read more on health disparities.
HHS, Heart Disease Organizations Join Forces to Vastly Reduce Premature Death Linked to Heart Conditions by 2025
Leaders from the World Heart Federation , the American Heart Association, the U.S. Department of Health and Human Services, and the American College of Cardiology are joining together to help cut premature mortality from cardiovascular disease by at least 25 percent by 2025. Key strategies will include secondary prevention efforts for people who have already experienced a heart incident, or have established heart disease, as well as primary prevention strategies in the United States and around the world. “Heart disease can touch anyone, no matter where you live,” said Nancy Brown, chief executive officer of the American Heart Association. “It will take the collective efforts of everyone from community leaders to healthcare professionals, educators and business leaders to stop this No. 1 killer at the national and global level...” Read more on heart health.
New Guidelines for Stroke Risk, Prevention in Women
The American Heart Association/American Stroke Association has published the first ever set of guidelines dedicated to stroke risk and prevention in women. The 86-page document appears in the journal Stroke and address risk factors distinct to women, including pregnancy, oral contraceptives, menopause and hormone replacement. It also covers factors that affect women more than men, including atrial fibrillation and migraine with aura. “We reviewed a large body of research to be able to summarize our current understanding of stroke risk and stroke prevention in women, information that is critically important for care providers and researchers in the field,” according to Judith Lichtman, MD, associate professor at the Yale School of Public Health and co-author of the study. “The guidelines are also important to empower women and their families to better understand their risk for stroke and be aware of ways they can minimize their likelihood of having a one.” Strokes are the third-leading cause of death among women in the United States.

Study: Indicators of Potential Heart Disease as Early as Age 18
Indicators of potential heart disease can be seen as early as age 18, according to a long-term study recently published in the Journal of the American Medical Association. Researchers found that elevated blood pressure at that age, as well as found distinct blood pressure patterns from ages 18-55, indicate people at high risk for calcification of coronary arteries by middle age. “This shows that your blood pressure in young adulthood can impact your risk for heart disease later in life,” said Norrina Allen, PhD, lead study author and assistant professor of Preventive Medicine at Northwestern University Feinberg School of Medicine, in a release. “We can’t wait until middle age to address it. If we can prevent their blood pressure from increasing earlier in life we can reduce their risk of future heart attacks and stroke.” Approximately one in three U.S. adults have hypertension.

American Society of Clinical Oncology Weighs in on Mammography
In response to a study published this week in the British Medical Journal which called into question the benefit of mammography, the American Society of Clinical Oncology (ASCO) issued a statement today saying that because mammography is similar to many other tests that can detect a condition that may never cause harm, the benefits of screening are likely to be greater for women who are at increased risk of developing breast cancer based on factors such as age and family history, than for women at average risk. It also stated no single study should be used to change screening policy and that all women should be encouraged to speak with their doctors about their personal risk for breast cancer, as well as the potential benefits and harms of mammography screening. ASCO and other cancer advocacy and women’s health groups have announced that they will be monitoring additional mammography studies now being conducted, and the American Cancer Society is expected to release new mammography recommendations later this year.

NHTSA Announces New Mandatory Label to Help Owners Instantly Identify Recall Mailings
The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) today announced that starting February 18, all manufacturers must use a distinctive label on the agency’s required mailings that notify owners of recalled vehicles or equipment.
The requirement was introduced to help owners instantly distinguish important recall notices arriving in their mailboxes from other mail and hopefully avoid mistakenly discarding the safety notices. NHTSA has also just launched the SaferCar app for Android devices that will provide information for car owners and shoppers, including recalls and safety performance. There is already a SaferCar app for iPhone, iPad and iPod Touch users. Other safety notification options from NHTSA include:
- Register Your Cars, Tires and Car Seats: Receive NHTSA email notifications when there is a recall by the federal government. There is no way to locate or notify individual owners of car seats or tires if the product is not registered with the manufacturer or NHTSA.
Check for Open Recalls on Used Cars: Verify with the previous owner or dealer whether a used car has been fixed by using www.safercar.gov, which provides a general search tool to help consumers identify recalls that may affect their vehicle.

AHA Releases Stroke Prevention Guidelines for Women
For the first time, the American Heart Association (AHA) has released stroke prevention guidelines for women. The guidelines outline stroke risks unique to women and provide evidence-based recommendations on how best to treat them, including:
- Women with a history of high blood pressure before pregnancy should be considered for low-dose aspirin and/or calcium supplement therapy to lower preeclampsia risks.
- Women who have preeclampsia have twice the risk of stroke and a four-fold risk of high blood pressure later in life. Therefore, preeclampsia should be recognized as a risk factor well after pregnancy, and other risk factors such as smoking, high cholesterol, and obesity in these women should be treated early.
- Pregnant women with moderately high blood pressure (150-159 mmHg/100-109 mmHg) should be considered for blood pressure medication; expectant mothers with severe high blood pressure (160/110 mmHg or above) should be treated.
- Women should be screened for high blood pressure before taking birth control pills because the combination raises stroke risks.
- Women who have migraine headaches with aura should stop smoking to avoid higher stroke risks.
- Women over age 75 should be screened for atrial fibrillation risks; a risk factor for stroke.

New Study Predicts Flu Severity
Researchers at St. Jude Children’s Research Hospital in Memphis say flu patients, regardless of age, who have elevated levels of three particular immune system regulators, called cytokines, early in the infection were more likely to develop severe flu symptoms and to be hospitalized than patients with lower levels of the same regulators. Study participants ranged in age from 3 weeks to 71 years.
The study, published in the American Journal of Respiratory and Critical Care Medicine, found that cytokine levels early in the infection were predictive of flu-related complications regardless of patient age, flu strain, the ability of the virus to replicate and other factors. The cytokines studied help to regulate inflammation caused by the body’s immune response to the flu until antibodies and T cells take over. Patients with the elevated cytokines seem to develop airway distress as a reaction to the immune response, a development separate from the effects of the flu virus. “We need to explore targeted therapies to address this problem separately from efforts to clear the virus, says study author Paul Thomas, PhD, an assistant member of the St. Jude Department of Immunology.

Community Health Worker Model Can Reduce Hospital Readmissions
A new study in JAMA Internal Medicine reports on a community health worker (CHW) program developed at the University of Pennsylvania School of Medicine that hired people from the local community to help discharged patients navigate the health care system and address key health barriers, such as housing instability or food insecurity. The study found that the intervention improved patient experiences and health outcomes and reduced hospital readmissions.
The Penn team tested the model in a randomized trial with 446 hospitalized patients who were either uninsured or on Medicaid, and lived in low-income communities in which more than 30 percent of the population lived below the Federal Poverty Level. More than one-third of all readmissions to the hospitals participating in the study come from a five-zip code region. Patients in the trial received support from CHWs hired for traits such as empathy and active listening. The CHWs connected during a patient's hospital stay and continued after they were discharged to help with issues including scheduling doctor appointments, accessing medications, or finding child care or shelter. The control group received routine hospital care, medication reconciliation, written discharge instructions, and prescriptions from the hospital. The CHW group had a 52 percent greater chance of seeing a primary care physician within two weeks after being discharged from the hospital and scores measuring a patient's confidence in managing their own care in the future more than doubled in the CHW group. While the two groups had similar rates of at least one hospital readmission (15 percent vs 13.6 percent), the CHW group was less likely to have multiple readmissions (2 percent vs 6 percent in the control group).

>>NewPublicHealth continues a new series to highlight some of the best public health education and outreach campaigns every month. Submit your ideas for Public Health Campaign of the Month to info@newPublichealth.org.
In honor of American Heart Month, held each February, the U.S. Environmental Protection Agency (EPA) has created a new Public Service Announcement (PSA) to educate the public and health care providers about the risks of air pollution to the heart.
"Over more than four decades of EPA history, we've made tremendous progress cleaning up the air we breathe by using science to understand the harmful effects of air pollution," said EPA Administrator Gina McCarthy. “While EPA continues to fight for clean air, Americans can take further action to protect their heart health by following the advice in our new PSA.”
One of EPA’s commitments in the U.S. Surgeon General’s National Prevention Strategy is to educate health care professionals on the health effects of air pollution, including heart risks. This PSA supports the Million Hearts Initiative, launched by the U.S. Department of Health and Human Services in September 2011, to prevent one million heart attacks and strokes by 2017.
Research has shown that air pollution can trigger heart attacks, stroke and worsen heart conditions, especially in people with heart disease—that’s one in three Americans. According to the EPA, very small particles are the pollutants of greatest concern for triggering health effects from exposure to air pollutants. These particles are found in transportation exhaust, haze, smoke, dust and sometimes even in air that looks clean. Particle pollution can also be found in the air at any time of the year.
The new PSA advises people with heart disease to check the daily, color-coded Air Quality Index forecast. At code orange or higher, particle pollution can be harmful to people with heart disease. On bad air quality days, it is recommended to reschedule outdoor exercise or to exercise indoors instead, and avoid exercising near busy roads.
Air Quality Index forecasts for more than 400 cities are available on the forecast map through a free AirNow app for iPhone and Android phones, and through the free EnviroFlash e-mail service. To sign up, visit here and click on the “Apps” or “EnviroFlash” icons.
Minimum Alcohol Prices Could Help Low-income, High-risk Drinkers
Setting a minimum price for alcohol would have a positive impact on low-income, high-risk drinkers, but little effect on low-income, moderate drinkers, according to a new study in The Lancet. British researchers at the University of Sheffield utilized a computer model to assess the impact of a 73 cents per unit of alcohol minimum on different demographics, finding it would have the greatest positive impact—reducing the amount of alcohol consumption—on the 5 percent of the population defined as high-risk drinkers. "Our study finds no evidence to support the concerns highlighted by government and the alcohol industry that minimum unit pricing would penalize responsible drinkers on low incomes,” said study co-author Petra Meier, director of the Sheffield Alcohol Research Group. “Instead, minimum unit pricing is a policy that is targeted at those who consume large quantities of cheap alcohol. By significantly lowering rates of ill health and premature deaths in this group, it is likely to contribute to the reduction of health inequalities." Read more on alcohol.
Smoking Linked to Most Common Type of Breast Cancer
Adding yet another health risk to the use of tobacco, smoking is linked to an increased risk for the most common type of breast cancer, according to a new study in the journal Cancer. Researchers at the Fred Hutchinson Cancer Research Center in Seattle conducted a population-based study of 778 patients, ages 20-44, with estrogen receptor positive breast cancer (the most common type) and 182 patients with triple-negative breast cancer; there were 938 cancer-free controls. They found that women who were current or recent smokers and had been smoking a pack a day for at least 10 years had a 60 percent increased risk of estrogen receptor positive breast cancer. "The health hazards associated with smoking are numerous and well known. This study adds to our knowledge in suggesting that with respect to breast cancer, smoking may increase the risk of the most common molecular subtype of breast cancer but not influence risk of one of the rarer, more aggressive subtypes," said Christopher Li, MD, PhD.

Low Testosterone Drugs Can Double Heart Attack Risk in Some Men
Ads asking men about their “low T”—or low testosterone levels—have become so common of late that in 2013 sales of the testosterone gel Androgel exceeded those of Viagra. However, a recent study indicates that men under the age of 65 with a history of heart disease see their heart attack risk double shortly after beginning testosterone therapy. The joint study from the UCLA Fielding School of Public Health, the National Institutes of Health and Consolidated Research Inc. appears in the journal PLOS ONE. Researchers decided to perform this larger study after three smaller studies raised concerns about the connection. "We decided to investigate cardiovascular risks of this therapy in a large health care database since these previous studies were modest in size and only focused on men 65 and older," said the study's senior author, Sander Greenland, MD, a professor of epidemiology at the UCLA Fielding School of Public Health and a professor of statistics in the UCLA College of Letters and Science. "Our study allowed us to examine cardiovascular risk in men under the age of 65 and to replicate the findings in men over 65." Read more on heart health.
Survey: Latinos See Diabetes as Greatest Family Health Concern
A new NPR/Robert Wood Johnson Foundation/Harvard School of Public Health poll found that Latinos see diabetes as the biggest health concern for their families. Almost 19 percent of Latinos surveyed cited diabetes as the top worry, including across both immigrant (19 percent) and non-immigrant (22 percent) populations. Cancer, at 5 percent, was the second-biggest concern. In addition to health and health care, the poll also asked about communities, financial situation and discrimination. According to the U.S. Centers for Disease Control and Prevention, Hispanic adults are 1.7 percent more likely than non-Hispanic whites to be diagnosed with diabetes, and 1.5 percent more likely to die from it.

Heart Attack Patients in ER Off-Hours Seeing Higher Mortality Rates
Heart attack patients who present during off-hours—at night and on weekends—are more likely to die, according to a new study from the journal BMJ. Their emergency care is also more likely to take longer than it would during normal hospital hours, including inflation of the coronary artery, which can take an additional 15 minutes. After analyzed records on 1,896,859 patients, researchers at the Mayo Clinic determined that heart attack patients who present during off-hours had a 5 percent relative increase in mortality—or an additional 6,000 U.S. deaths. The study’s authors concluded that emergency departments "should focus on improving their off-hour care, with the goal of providing consistently high quality care 24 hours a day and seven days a week."

Study: HPV Vaccination Rate Remains Low, More Physician Recommendations Needed
Only 14.5 percent of girls ages 11 and 12 have received at least one does of the human papillomavirus (HPV) vaccination, with only 3 percent having completed a three-dose series, according to a new study in the American Journal of Preventive Medicine. The study from the Moffitt Cancer Center indicates that increasing the rate of physician recommendations, which so far remains low, could do much to up the vaccination rate and cut the risk of cancer. The vaccination protects against the two types of HPV that cause 70 percent of cervical cancer cases. “This study demonstrates that the change in consistent HPV vaccine recommendations to early adolescent females was modest, and for older adolescent females was virtually nonexistent, from three to five years after the vaccine became available,” explained Susan T. Vadaparampil, PhD, MPH, associate member of the Health Outcomes and Behavior Program at Moffitt. “Physician recommendation is central to increasing HPV vaccination rates because it is one of the most important predictors of whether a patient gets the HPV vaccine.” Read more on cancer.
Black Women Have Highest Rates of High Blood Pressure
More black women have high blood pressure than black men and white men and women, according to a new study in Circulation: Cardiovascular Quality and Outcomes.
The study included 70,000 people in the 12 southeastern states that are often referred to as the “stroke belt” because they collectively have a high rate of stroke incidence. Among the study participants, the high blood pressure rate among black women was 64 percent. Among white women the rate was 52 percent and among both black and white men the rate was 51 percent.
“For many years, the focus for high blood pressure was on middle-aged men who smoked; now we know better,” said Uchechukwu Sampson, MD, MPH. MBA, a lead author of the study and assistant professor of medicine at Vanderbilt University Medical Center in Nashville, Tenn. “We should look for [high blood pressure] in everyone and it should be treated aggressively — especially in women, who have traditionally gotten less attention in this regard.”
Dr. Sampson’s work was supported in part by the Harold Amos Medical Faculty Award of the Robert Wood Johnson Foundation. Read more on health disparities.
Over 40 Million Americans Experienced Mental Illness in 2012
Nearly one in five American adults, or 43.7 million people, experienced a diagnosable mental illness in 2012, a similar number to 2011, according to a new report from the Substance Abuse and Mental Health Services Administration (SAMHSA).
SAMHSA also reported that, consistent with 2011, less than half (41 percent) of these adults received any mental health services in the past year. And among adults with mental illness who reported an unmet need for treatment, the top three reasons given for not receiving help were:
- they could not afford the cost;
- they thought they could handle the problem without treatment; and
- they did not know where to go for services.
The Department of Health and Human Services recently launched MentalHealth.gov to help people find easy-to-understand information about basic signs of mental health problems, how to talk about mental health and mental illness, and how to locate help.
The recent SAMHSA report also found that 9 million American adults 18 and older (3.9 percent) had serious thoughts of suicide in the past year; 2.7 million (1.1 percent) made suicide plans and 1.3 million (0.6 percent) attempted suicide. People in crisis or who know someone they believe may be at immediate risk of attempting suicide can call the National Suicide Prevention Lifeline 1-800-273-TALK (8255) or go to SuicidePreventionLifeline.org, which provides immediate, free and confidential round-the-clock counseling to anyone in need throughout the country, every day of the year.

NHTSA Extends Its Partnership with Auto Makers on Technology to Stop Drunk Drivers
The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) has extended, for five years, its agreement with the Automotive Coalition for Traffic Safety (ACTS), made up of 15 auto makers, to continue researching advanced alcohol detection technology that could prevent vehicles from being driven by a drunk driver.
Under the partnership, NHTSA is working with ACTS to develop a car system that could accurately and reliably detect when a driver is above the legal alcohol limit of 0.08 BAC adopted by all 50 States and territories. The automatic system would be enabled every time the car is started, but not pose an inconvenience to a non-intoxicated driver.
“In this age of innovation, smart technology may be the breakthrough we need to prevent drunk drivers from getting behind the wheel and endangering the safety of others on our roads,” said NHTSA Administrator David Strickland. “The research program has shown significant promise to date, offering real potential in the future to prevent several thousand deaths annually.”
NHTSA expects to have models ready for testing in 2015. In 2012, deaths in crashes involving drunk drivers increased 4.6 percent, resulting in 10,322 deaths — up from 9,865 in 2011. Read about NHTSA’s “Drive Sober or Get Pulled Over" campaign.
NHTSA: Motorcoaches, Large Buses to Require Seatbelts for All Passengers and Driver
New motorcoaches and large buses will be required to provide lap and shoulder seatbelts for all passengers and driver, under a new rule issued by the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA). While the buses are an overall safe way to travel, the large numbers of people they carry and the high speeds at which they travel mean a single collision can lead to a significant number of injuries, according to NHTSA. An average of 7,934 riders are injured each year in motorcoaches, and an average of 21 passengers are killed. "Buckling up is the most effective way to prevent deaths and injuries in all vehicular crashes, including motorcoaches," said Federal Motor Carrier Safety Administrator Anne S. Ferro, in a release. "Requiring seat belts in new models is another strong step we are taking to reach an even higher level of safety for bus passengers." The rule will apply to buses with a gross vehicle weight rating (GVWR) greater than 26,000 pounds,) excluding transit buses and school buses. Read more on transportation.
Study: Women With Breast Cancer Should Get Mammograms Every 12 to 18 Months
Breast cancer patients should undergo mammograms every 12 to 18 months to determine whether their cancer has spread to the lymph nodes, according to a new study to be presented today at the annual meeting of the Radiological Society of North America. Study researcher Lilian Wang, MD, evaluated more than 300 women who were diagnosed with breast cancer because of a routine mammogram, dividing them into three groups based on their treatment history. She found that only 9 percent of the women who had 12- to 18-month intervals between mammograms saw their cancer spread to their lymph nodes; the rates were 21 percent for those who waited one-and-a-half to three years and 15 percent for those who waited three or more years. "If you catch someone with early stage cancer, they are going to need less extensive surgery, and maybe no chemo," said Laura Kruper, MD, director of the Cooper-Finkel Women's Health Center at the City of Hope Cancer Center, in Duarte, Calif., who was not a part of the study. "[The new study] adds more power behind the fact that we do need screening mammograms starting at age 40 and every year.” Read more on cancer.
FDA: Certain HeartStart AEDs May Not Work During Cardiac Emergencies
The U.S. Food and Drug Administration (FDA) announced yesterday that certain automated external defibrillator (AED) devices made by Philips Medical Systems may not function properly when needed. In a new safety communication, FDA revealed that the devices may not deliver the needed shock to restore normal heart rhythm during a cardiac emergency. “The FDA advises keeping all recalled HeartStart AEDs in service until you obtain a replacement from Philips Healthcare or another AED manufacturer, even if the device indicates it has detected an error during a self-test,” said Steve Silverman, director of the Office of Compliance in the FDA’s Center for Devices and Radiological Health. “Despite current manufacturing and performance problems, the FDA considers the benefits of attempting to use an AED in a cardiac arrest emergency greater than the risk of not attempting to use the defibrillator.” Read more on heart health.
Study: Gay, Bisexual Men Who Know Their HIV Status Less Likely to Engage in Risky Sex
Gay and bisexual men who know their HIV status are far less likely to engage in unprotected sex, which in lessens the sexual risk both for them and for their partner, according to the U.S. Centers for Disease Control and Prevention's (CDC) latest Morbidity and Mortality Weekly Report. An analysis of HIV-positive men who have sex with men (MSM) in 20 U.S. cities found that about 33 percent of those who did not know their status engaged in unprotected sex with a partner, and also did not know the status of the partner; men who knew their status were 60 percent less likely to do so, for an overall rate of 13 percent. MSM account for about two-thirds of new HIV infections and about half of the 1.1 million people in the United States with HIV. "While we remain concerned about potentially increasing levels of sexual risk, it is encouraging to see that risk is substantially lower in those who know they have HIV," said CDC Director Tom Frieden, MD, MPH. "HIV testing remains one of our most powerful tools to reverse the epidemic. Everyone should know their HIV status." Read more on HIV/AIDS.
Improved HealthCare.gov Faces Next Challenges
HealthCare.gov, the online portal for the Affordable Care Act, faces another test starting today as the Obama administration announced it met a weekend deadline to make the site easier to use and more accessible for most users. The original launch of the site was met with must frustration across the county as many people were unable to navigate the site properly or even to log in. The administration now expects a rush of people--both a backlog and people who have yet to try the site--to enroll by the December 23 deadline for coverage that would begin January 1. Multiple organizations, including Enroll America and AIDS Alabama, have announced plans to help people enroll. Jeffrey Zients, an administration advisor, warned that the post-Thanksgiving wave of enrollment could still overwhelm the servers at times. Read more on the Affordable Care Act.
Study: Energy Drinks Can Increase Strain on Heart
People who consume energy drinks can experience rapid heart contractions and increased strain on the heart up to an hour later, according to new research to be presented today at the annual meeting of the Radiological Society of North America, in Chicago. The findings raise concerns over the effects of caffeine and taurine on heart health, especially for people who already suffer from heart disease. Researchers used magnetic resonance imaging to measure the heart function of 18 health people both before and after they consumed an energy drink, finding an average 6 percent increase in the heart contraction rate afterward. "We know there are drugs that can improve the function of the heart, but in the long term they have a detrimental effect on the heart," said Williams, a cardiology professor at Wayne State University School of Medicine, in Detroit. Researchers noted that further study is needed to determine the reason for the apparent link. Read more on heart health.
