Beta blockers are go-to meds for many people who’ve survived a heart attack. However, new Swedish research has found that they might not be needed for heart attack survivors whose hearts have retained a normal pumping ability.  Using them in this group might even raise patients’ odds for depression, the data showed. “We found that beta blockers led to slightly higher levels of depression symptoms in patients who had had a heart attack but were not suffering from heart failure,” said study lead author Philip Leissner, a doctoral student in cardiac psychology at Uppsala University.   “At the same time, beta blockers have no life-sustaining function for this group of patients,” he said in a university news release. His team published its findings recently in the European Heart Journal. Heart doctors have for decades relied on beta blocker medications to help heart patients — the drugs work by lowering the effects of adrenaline on the heart.  But recent advances mean there are now more pharmaceutical options for cardiologists to pick from for people who’ve survived a heart attack, putting the use of beta-blockers into question. According to Leissner’s team, that’s especially true for folks who have survived a heart attack but whose cardiac pumping action has retained its efficacy. In a study published in April, the Swedish researchers found beta-blockers to be unnecessary for this…  read on >  read on >

Asthma is associated with memory problems in children, a new study has found. Further, the early onset of asthma might worsen potential memory deficits in kids, researchers found. This is the first study to make such a connection, researchers said. “This study underscores the importance of looking at asthma as a potential source of cognitive difficulty in children,” said senior researcher Simona Ghetti, a professor of psychology in the University of California-Davis Center for Mind and Brain. “We are becoming increasingly aware that chronic diseases, not only asthma but also diabetes, heart disease and others may place children at increased risk of cognitive difficulties,” Ghetti added in a news release. “We need to understand the factors that might exacerbate or protect against the risks.” For the study, researchers analyzed data from more than 2,000 9- and 10-year-olds with asthma. In the U.S., roughly 4.6 million children have asthma. “Childhood is a period of rapid improvement in memory and, more generally, cognition. In children with asthma that improvement may be slower,” lead researcher Nicholas Christopher-Hayes, a doctoral candidate in psychology at UC Davis, said in a news release. His team found that children with asthma had lower scores in tests of episodic memory, the specific type of memory related to experiences and emotions. In a smaller sample of nearly 500 kids followed for two years, researchers…  read on >  read on >

Americans’ well-being varies widely between different regions of the nation, a new study reports. People in the southern U.S., Appalachia and the Rust Belt states score lowest on the Human Development Index (HDI), a composite measure that includes a population’s life expectancy, education and income, researchers report in The Lancet. The highest levels of well-being occur among people living in parts of Colorado, Maryland, New York, California, Virginia and Washington, D.C., researchers said. “As a new federal administration prepares to take actions aimed at solving the most pressing economic, social, and health issues the US population faces, this study underscores the urgent need for action by policymakers, educators, and public health experts,” senior researcher Dr. Christopher Murray, director of the Institute for Health Metrics Evaluation at the University of Washington in Seattle, said in a news release. “IHME’s findings further emphasize the critical need to develop highly targeted social programs to dismantle deep-rooted structural inequalities in the US,” Murray added.   The United Nations Development Program created the HDI as a measure to help track well-being between nations, researchers said in background notes. For this study, U.S. researchers adapted the HDI to gauge well-being based on years of education, household income and life expectancy estimates. Overall, the average U.S. HDI increased gradually from 2008 to 2019, then declined in 2020 due to decreases in lifespan linked…  read on >  read on >

Lives lost to obesity-related heart disease have nearly tripled over the past twenty years, a new study reports. Heart disease deaths linked to obesity increased 2.8-fold between 1999 and 2020, according to findings presented today at the American Heart Association’s annual meeting in Chicago. The increase occurred especially among middle-aged men, Black adults, Midwesterners and rural residents, researchers found. “Obesity is a serious risk factor for ischemic heart disease, and this risk is going up at an alarming rate along with the increasing prevalence of obesity,” lead researcher Dr. Aleenah Mohsin, a post-doctoral research fellow at Brown University in Providence, R.I., said in a news release. Ischemic heart disease is caused by clogged arteries, researchers said. Less blood and oxygen can reach the heart, increasing the risk of a heart attack. Obesity contributes to the risk of this form of heart disease by increasing cholesterol levels, promoting high blood pressure, raising the likelihood of type 2 diabetes and causing poor sleep. “It is important for everyone, particularly people in high-risk groups, to take steps to manage their weight and reduce their risk of heart disease,” Mohsin said. “Lifestyle changes are key, such as eating healthier, exercising regularly and working with health care professionals to monitor heart health.” For the study, researchers analyzed public health data to review heart disease trends in recent decades. More than…  read on >  read on >

Babies born preterm face a life of lowered prospects, a new study warns. Adults who were preemies are less likely to achieve higher education or snag a high-paying job, researchers reported Nov. 6 in the journal PLOS One. What’s more, the earlier preterm a baby is born, the worse his or her future prospects appear to be. “Our findings suggest that the development of long-term supports [including psychological, education and vocational resources] that go beyond clinical care may help mitigate the longer-term effects of preterm birth,” said researcher Petros Pechlivanoglou, with The Hospital for Sick Children in Toronto. Preterm birth is known to increase a baby’s risk of intellectual and developmental difficulties, according to the March of Dimes. About 10% of all babies worldwide are born preterm. For the study, researchers analyzed health, education and employment data on all live births that occurred in Canada between 1990 and 1996, a pool of about 2.4 million people. Results showed that babies born before 37 weeks of gestation are 17% less likely to go to college, 16% less likely to graduate with a college degree and 2% less likely to be employed. The average income of adults who were born preterm is 6% lower than those born at term, researchers said. For individuals born at the earliest gestation, 24 to 27 weeks, those associations were even stronger,…  read on >  read on >
