Keeping fit could help you avoid heart rhythm disorder and stroke, new research suggests. The study of more than 15,000 people found that physical fitness is linked with a lower likelihood of developing both conditions. Atrial fibrillation – irregular and often fast heartbeat – is the most common heart rhythm disorder, affecting more than 40 million people worldwide. The findings indicate that keeping fit may help prevent atrial fibrillation and stroke Dr Shih-Hsien Sung Patients with the condition have a five-fold higher risk of stroke than their peers, experts suggest. Study author Dr Shih-Hsien Sung of the National Yang Ming Chiao Tung University, Taipei, Taiwan said: “This was a large study with an objective measurement of fitness and more than 11 years of follow up. “The findings indicate that keeping fit may help prevent atrial fibrillation and stroke.” The study examined whether fitness was related to the likelihood of developing atrial fibrillation. It included 15,450 people without atrial fibrillation who were referred for a treadmill test between 2003 and 2012. Fitness was assessed using a protocol where people are asked to walk faster and at a steeper grade in successive three-minute stages. Their fitness was calculated according to the rate of energy expended, which was expressed in metabolic equivalents (METs). Follow-ups looked at whether people developed atrial fibrillation, stroke, heart attacks, or whether they had died. During an average follow-up period of 137 months, 515 participants (3.3%) developed atrial fibrillation. Each one MET increase on the treadmill test was associated with an 8% lower risk of atrial fibrillation, 12% lower risk of stroke and 14% lower risk of major adverse cardiovascular events (MACE – a composite of stroke, myocardial infarction and death). People in the study were divided into three fitness levels according to METs achieved during the treadmill test. The levels were low (less than 8.57 METs), medium (8.57 to 10.72) and high (more than 10.72). According to the findings presented at the ESC Congress 2023 in Amsterdam, the probability of remaining free from atrial fibrillation over a five-year period was 97.1%, 98.4% and 98.4% in the low, medium and high fitness groups, respectively.

The White House on Wednesday strongly denied that the US government posed any threat to an ex-Senate staffer who has claimed President Joe Biden sexually assaulted her in a Senate office building hallway in the 1990s. The former staffer, Tara Reade, announced on Tuesday that she has moved to Russia, where she said during an interview with the state-owned Sputnik News website that she feels “surrounded by protection and safety” there. Asked about her claims in light of her announcement that she has moved to Russia and is seeking citizenship there, National Security Council spokesperson John Kirby replied: “We'd be loath to comment on the on the musings of a potential Russian citizen.” Pressed further on whether the White House believes her allegations against Mr Biden could have been movtivated by an affinity for Russia, Mr Kirby said he “could not get inside her head and speak for her motivations and intentions”. But he did specifically address Ms Reade’s claim that she has moved to Russia because the US government was a risk to her life, calling those allegations “absolutely false” and “baseless”. “There’s nothing to that,” he added. Ms Reade, who worked for Mr Biden during a brief period in 1993, accused the then-former vice president of touching her inappropriately in 2019, when Mr Biden was contemplating entry into the 2020 presidential election. In mid-2020, when he was poised to secure the Democratic Party’s nomination for president, she claimed he’d sexually assaulted her in a heavily-trafficked hallway in the Russell Senate Office Building. Mr Biden has strenuously denied the allegations. The former Senate staffer’s credibility took a hit after news outlets began scrutinizing her background after she made the assault allegations against Mr Biden. A university she attended, Antioch University, disputed her claim to have earned a Bachelor’s degree while studying there, and former associates came forward to recount instances in which they’d felt she’d been dishonest or deceitful in her dealings with them. A well known attorney, Douglas Wigdor, terminated an attorney-client relationship with her in May 2020 after it was revealed that she had not earned a degree from Antioch as she’d claimed publicly.
