Heart failure warning as people told not to ignore surprisingly common symptom
Hearing impairment increases a person's risk of heart failure, a new study has found.
The study found that psychological distress caused by hearing impairment plays a 'notable' role in developing problems with the heart.
Experts in China analysed UK Biobank data from 164,431 people who had completed tests designed to determine hearing ability for the study.
Of the total, some 160,062 did not wear hearing aids.
They were put into three groups based on their performance in a digit triplet test (DTT), which screens for hearing problems by using random combinations of digits against background noise.
All of the people initially included in the analysis did not have heart failure, but, over a follow-up period of more than 11 years, some 4,449 developed the condition.
Heart failure happens when the heart cannot pump blood effectively, leading to symptoms like fatigue, shortness of breath, and swelling in the legs and ankles.
It estimated that more than one million people in the UK have the long-term condition.
The researchers found those who had a higher speech reception threshold (SRT) – meaning they needed louder speech to understand words – had an increased risk of heart failure.
They said: 'Compared with those with normal hearing, participants with insufficient hearing, poor hearing, or hearing aid use had higher heart failure risks.'
High SRT levels were also associated with psychological distress, social isolation and neuroticism among those who did not wear hearing aids.
The researchers added: 'We have been the first to demonstrate that poor hearing ability is significantly associated with a higher risk of incident heart failure in the general population.
'Psychological factors, especially psychological distress, play a significant mediating role in this association.
'If further confirmed, hearing impairment may be a potential risk factor or marker for incident heart failure in the general population, highlighting the importance of integrating hearing health assessments into broader cardiovascular risk evaluation frameworks.
'Moreover, strengthening psychological intervention in people with hearing impairment may be an important path and strategy to reduce the risk of heart failure.'

Naps associated with increased risk of death, report says
June 5 (UPI) -- An afternoon snooze might seem appealing to middle-aged folks and seniors, but these naps could carry a high cost. People with certain types of napping patterns have a greater risk of an early death, researchers are slated to report at an upcoming meeting of the American Academy of Sleep Medicine. "People who slept longer during the day, had irregular daytime sleep patterns, or slept more around midday and early afternoon were at greater risk, even after accounting for health and lifestyle factors," lead researcher Chenlu Gao, a postdoctoral research fellow at Massachusetts General Hospital in Boston, said in a news release. The findings call into question the whole concept of the "power nap." For the study, researchers analyzed data on more than 86,500 people participating in the UK Biobank long-term health research project. These folks had their sleep habits monitored for a week using wrist devices, and researchers compared those habits to death records. Their average age was 63 at the time their napping was tracked. Nearly 5,200 people died during a follow-up of 11 years, researchers said. Results showed an increased risk of premature death for: • People who tended to take longer daytime naps • Folks whose napping patterns fluctuated frequently • People who napped between 11 a.m. and 3 p.m. This last observation contradicts academy guidelines, which encourages adults to limit themselves to "power naps" of no more than 20 to 30 minutes in the early afternoon, researchers noted. Naps that last longer than a half-hour can cause grogginess that undercuts the potential helpfulness of a siesta, researchers said. "Interestingly, the data that shows risks associated with napping around midday and early afternoon contradicts what we currently know about napping, so further research on that link could be warranted," Gao said. Gao is to present these findings Wednesday during the AASM's annual meeting in Seattle. Findings presented at medical meetings should be considered preliminary until published in a peer-reviewed journal. More information The Mayo Clinic has more on napping for healthy adults.

Your ‘five-a-day' now includes chocolate... and wine
For those people who find cramming in five portions of fruit and veg a day about as appealing as limp lettuce, scientists have good news: now you can count red wine and dark chocolate. A new five-a-day diet including tea, apples, oranges and berries – all foods rich in chemicals called flavonoids - will help people to live longer, a study has found. Flavonoids have a range of benefits, including lowering high blood pressure and dampening inflammation. Scientists have long known them to be good for health, but the new study is the first to investigate the benefits of a diversity of different flavonoids, not just the quantity. There are five main groups of flavonoids covering dozens of unique chemicals, but one main tranche is anthocyanins, found in abundance in grapes and red wine. Tea is rich in flavan-3-ols, another flavonoid, while orange juice is full of flavonones, and kale has high levels of flavones. Some foods, such as apples and tea, contain several flavonoids of different categories, while some only contain one. Scientists looked at the benefits of a diversity of these chemicals in a person's diet by assessing almost 125,000 Britons enrolled in the UK Biobank. Specific food and drink intake was compared to health outcomes over a decade of follow-up by scientists at Queen's University Belfast. Participants who consumed at least 1,000 milligrams of flavonoids a day were a fifth less likely to die during the study period, data showed, confirming that flavonoid quantity was linked to better health. Further analysis on the impact of flavonoid diversity found people in the lowest 20 per cent of the study consumed on average just one food product which was rich in flavonoids a day. Those in the top 20 per cent who ate five portions of flavonoid-rich foods a day were found to have a 16 per cent lower risk of death during the study period. Prof Aedín Cassidy, study author and chair in nutrition and preventive medicine at Queen's University Belfast, told The Telegraph: 'A flavonoid 'five-a-day' has the potential to reduce mortality. 'The data suggest that there is a benefit to consuming a wide range of flavonoids beyond that of simply consuming a high quantity as different flavonoids work in different ways, some improve blood pressure, others help with cholesterol levels and decrease inflammation. 'So having a variety of flavonoid-rich foods is important – eg one apple, a handful of berries, two cups of tea, and one orange. Other rich sources are onions, red wine, grapes, plums, and red cabbage.' People who hit their flavonoid five-a-day were also found to be 10 per cent less at risk of cardiovascular disease, when accounting for factors such as sex, education, BMI, profession, income, alcohol and smoking habits, prior medical history and other aspects of diet. The cancer risk was also 20 per cent lower for five-a-dayers compared to those who ate just one of their five-a-day, the study found. Risk of respiratory conditions was eight per cent lower, data showed, and there was no link for neurodegenerative conditions. 'Our findings highlight the importance of consuming a diverse range of flavonoids for the management of chronic disease risk, which, from a public health perspective, provides support for consuming a variety of flavonoid-rich foods such as green and/or black tea, berries, apples, oranges and grapes,' said the study authors in their paper. 'The collective actions of multiple flavonoids appear to lead to greater health protection compared with single subclasses or compounds. 'We found that consuming both a higher quantity and wider diversity of dietary flavonoids appears better for longer-term health than higher intakes of either component alone.'

Misophonia Has Genetic Links to Depression And Anxiety, Study Finds
Most of us can relate to feeling uncomfortable when someone scrapes their nails down a chalkboard. For those suffering the condition misophonia, sounds like slurping, snoring, breathing, and chewing and draw an equally stressful response. A study published in 2023 by researchers in the Netherlands suggests the condition shares genes with mood disorders such as anxiety, depression, and PTSD. University of Amsterdam psychiatrist Dirk Smit and colleagues analyzed the genetic data from the Psychiatric Genomics Consortium, UK Biobank, and 23andMe databases and found people who self-identified as having misophonia were more likely to have genes associated with psychiatric disorders, as well as tinnitus. Watch the clip below for a summary on their findings. Patients with tinnitus – a persistent, shrill ringing in the ears – are also more likely to have psychological symptoms of depression and anxiety. "There was also an overlap with PTSD genetics," Smit told Eric W. Dolan at PsyPost. "This means that genes that give a sensitivity to PTSD also increase the likelihood for misophonia, and that could point to a shared neurobiological system that affects both. And that could suggest that treatment techniques used for PTSD could also be used for misophonia." This doesn't mean misophonia and these other conditions necessarily have shared mechanisms, only that some of the genetic risk factors may be similar. Previous research found people who experience misophonia are more likely to internalize their distress. Smit and team's research, published in 2023, also backed this up, showing strong links with personality traits such as worry, guilt, loneliness, and neuroticism. Responses to a triggering sound can range from irritation and anger to distress that interferes with everyday life. "It has been argued… that misophonia is based on the feelings of guilt about the evoked irritation and anger rather than behavioral expressions of anger itself that causes the distress," write Smit and team. People with autism spectrum disorder ( ASD) were less likely to experience misophonia. This was unexpected as those with ASD have a decreased tolerance to sounds. "Our results suggest that misophonia and ASD are relatively independent disorders with regard to genomic variation," the researchers write in their paper. "It raises the possibility that other forms of misophonia exist, one that is mostly driven by conditioning of anger or other negative emotionality to specific trigger sounds moderated by personality traits." Smit and colleagues caution their data was mostly European so the same links may not show up in different populations. What's more, misophonia was not medically diagnosed in their data samples, only self-reported which may also skew the results. But their study also provides clues for where further research could focus to find the biological mechanism behind misophonia. A 2023 survey suggests misophonia is more prevalent than previously thought, making studies like this one invaluable for understanding how our perception of the world links with our mind's ability to cope within it. This research was published in Frontiers in Neuroscience. An earlier version of this article was published in October 2024.
