I'm a heart doctor who sees thousands of preventable deaths – here are five things EVERYONE should do before it's too late

A leading cardiologist has revealed the five essential things we should all do to avoid an early death—and insists 'it's not just about exercise and salads'.
In an Instagram post viewed nearly 500,000 times, Memphis-based medic Dr Dmitry Yaranov warns that sleep, pollution, stress, oral health and diet all play a major role heart health.
'After treating thousands of patients with heart failure, these are the things I wish more people knew before it was too late.
'Here's what's actually affecting your heart—and nobody's talking about it,' he said in the viral video in which he listed the five points in the caption.
'Cardiovascular health isn't just about exercise and salads,' the expert added. 'It's sleep, stress, air, access, and even your gut.'
Getting fewer than eight hours' sleep a night can raise your risk of heart failure, stroke or sudden death, he warned beneath the 30-second clip.
Blood pressure usually drops during sleep—but poor sleep disrupts this, causing sustained high blood pressure, a key driver of heart disease, according to the British Heart Foundation.
Dr Yaranov also noted that daily exposure to air pollution—'breathing in exhaust every day'—can harden the arteries, leading to plaque build-up, restricted blood flow and a higher risk of heart attacks.
In a viral video shared to Instagram that has been seen nearly 500,000 times, leading cardiologist Dr Dimitry Yaranov has said sleep, pollution, stress, teeth health, and diet can all have a major impact on your heart
Regularly sleeping less than the recommended eight hours a night can raise your risk of heart failure, stroke, and sudden death
Next, he explained that constantly 'pushing through' stress can raise levels of cortisol—the body's main stress hormone—which, in excess, triggers high blood pressure and inflammation that damages blood vessels.
Oral health is another unlikely factor that can cause heart issues, which the doctor added to his list.
Improper care of your teeth can cause gum disease and the inflammation associated with this puts you at a higher risk of heart attack.
Another significant issue he pointed out was that people should also focus more on improving their gut health as the microbiomes help regulate blood pressure and cholesterol.
While living in an area with poor access to healthy food will only lead to worse cardiac outcomes, he then warned.
It comes as an epidemic of the disease has hit young people, experts warned last year.
Early deaths from heart disease hit their highest level in more than a decade, figures revealed. But now obesity, diabetes and undiagnosed high blood pressure are reversing six decades of progress.
Data analysed by the British Heart Foundation shows progress in the battle against the killer condition appears to have come to an end.
The latest figures for 2022 reveal that heart disease killed 80 out of every 100,000 people in England – the highest rate since 2011, when it was 83.
Heart fatalities in the under-75s have risen for three consecutive years.

Mom Captures Moment With Toddler, Just Days Later She'll Be Gone
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A mom from Ontario, Canada, captured a moment with her toddler, not knowing it would be one of the last memories together. Tamara Spearing, 31, posted a reel on Instagram holding and kissing her daughter. Days later, Gwendolyn was gone. Spearing told Newsweek that she was pregnant with Gwendolyn at 26. She had just bought her first home and was working two jobs. From left: Tamara Spearing holds her toddler daughter in her arms and kisses her head in dark lighting. From left: Tamara Spearing holds her toddler daughter in her arms and kisses her head in dark lighting. @tamaraspearing_ Spearing's days were full—friends, family, healthy living and big dreams. "I had full trust in the universe and what life was going to look like for me," she said. "That was until my life drastically changed within a matter of days." Gwendolyn was what Spearing called her "pleasant surprise." While her pregnancy was unplanned, she said she quickly embraced it. "I remember daydreaming what my child would look like; who they would grow up to be," Spearing said. "For me, my pregnancy was just the beginning of something amazing, and I was so, so excited to be a mama." At 28 weeks and five days, Spearing went into premature labor—a terrifying experience that unfolded while she was visiting Gwendolyn's father, who had recently been admitted to the ICU after a serious accident. "I didn't want to believe it as I was hardly into my third trimester," she added. Spearing walked herself to the labor and delivery floor, where she was met by a team of specialists. "I faintly remember looking over to the bedside nurse, asking her what I should expect and begging and pleading for a safe arrival of my baby," Spearing said. "I told the nurse, 'That wasn't my birth plan. I don't even have a nursery at home.' "She looked at me and said, 'Hunny, there is no such thing as a birth plan'," Spearing said. Within two hours and just three pushes, Gwendolyn was born at 2 pounds, 10 ounces. What followed were months of medical hurdles. Gwendolyn was diagnosed with Esophageal Atresia with Tracheoesophageal Fistula (EA/TEF)—a rare congenital condition where the esophagus doesn't connect to the stomach. Gwendolyn's prematurity brought additional complications: brain bleeds, underdeveloped lungs, multiple surgeries, code blues (where a patient requires resuscitation or is in need of immediate medical attention) and long hospital stays. Overall, Gwendolyn spent 170 days in hospital before being cleared to go home. Against the odds, she was thriving and hitting every milestone, according to her mom. "Appointments were further and farther between; she was attending playgroups and making friends; she was learning and discovering as a child should be at her age," Spearing said. "For the first time in her life, she was able to be just a kid." Then, on April 5, their world came crashing down. "For us, it was a normal day," Spearing added. "Little did I know this day would change my life forever." That evening, Gwendolyn's heart stopped. The autopsy provided no definitive cause. Some specialists suspect a catastrophic seizure or undetected heart failure. Spearing explored genetic counseling in the aftermath but was overwhelmed by the lack of answers. "I may never know why my daughter passed, and although I know now sometimes things just aren't meant to have an explanation, I still lay awake at nights contemplating the days leading up to her death and wondering if there was something I missed and if there was something apparent; maybe I could have saved her," Spearing said. Now, three years later, grief remains a constant companion. Spearing said that she barely remembers anything after Gwendolyn passed. "I was very angry. I lost trust in the universe and I questioned my beliefs," she added. "I wanted nothing more than to wake up from this nightmare that I was living in. I couldn't understand why a beautiful, innocent soul, who fought so hard to be here, only to be taken so abruptly." Out of her grief, Spearing created The Gwen Effect, a foundation honoring her daughter's legacy. It supports premature infants and children with complex medical conditions, funds research, and offers community support for grieving families. "I found a way of turning my pain into a purpose," Spearing said. "I continue to speak on grief and life after loss as I truly believe it is something that needs to be talked about more." The foundation's mission is clear: raise awareness, provide resources and create spaces where both grief and hope can coexist. Through it, Gwendolyn continues to touch lives. "Gwen was a ray of sunshine," Spearing said. "She was born tiny but mighty. Her passion for life while in and out of hospital showed us and many others how precious our time is. She was strong and brave."

FDA: More cucumbers, ready-to-eat products recalled in growing salmonella outbreak
A Maryland food company has recalled specific salsa and cucumber products because they were made with cucumbers that are possibly contaminated with salmonella. TGD Cuts, LLC of Jessup, Maryland, is recalling some tub and tray products because they contained cucumbers from Boynton Beach, Florida-based Bedner Growers Inc., which have been linked to a salmonella outbreak. TGD Cuts distributed the affected products, which included salsas, sliced cucumbers and cucumber spears, to retail and foodservice locations in Maryland, Virginia, Pennsylvania, New Jersey, and North Carolina, according to the Food and Drug Administration (FDA). The products had use-by dates ranging from May 20 to May 28 and are unlikely to be in stores or being used. No illnesses have been reported in connection with the products, the FDA said. Egg recall: Brown eggs sold at some Walmart stores have salmonella risk The initial May 19 recall involved cucumbers sold directly to consumers at Bednar's Farm Fresh Market, according to notices published May 19 by the Centers for Disease Control and Prevention (CDC) and the FDA. Subsequent recalls have been announced by grocers such as Harris Teeter, Kroger and Walmart for repackaged cucumbers for resale under different brand names or those used in ready-to-eat products, including vegetable trays and salads. The cucumbers, distributed by Fresh Start Produce Sales of Delray, Florida, also led to Target recalling individual cucumbers on May 30, specifically cucumber two-packs and various prepared foods products. In addition to the growing cucumber-related recall, other products have been recalled recently for potential salmonella contamination. The FDA on May 28 upgraded a recall of tomatoes distributed in three southern states to a Class I recall, meaning consumption of the food could cause serious health complications or lead to death. Then, on June 6, the CDC and FDA linked brown eggs sold in nine states – including at some Walmart stores – to an ongoing Salmonella Enteritidis outbreak, in which 79 people have been sickened and at least 21 hospitalized. Customers who purchased any products from TGD Cuts should get rid of them or return them for a full refund. Here is the list of products recalled due to a possible salmonella risk. Salmonella poisoning causes about 1.35 million illnesses, 26,500 hospitalizations, and 420 deaths each year in the U.S., according to the CDC and FDA. Symptoms, which include diarrhea, fever and stomach cramps, will usually occur six hours to six days after exposure and may last up to seven days. Symptoms from severe infections may include aches, headaches, elevated fever, lethargy, rashes, and blood in urine or stool. Mike Snider is a reporter on USA TODAY's Trending team.

Will Trump's policies kill Massachusetts' life sciences leadership?
Advertisement Although the industry is centered in eastern Massachusetts, there's a statewide benefit from all the tax dollars those businesses and workers pay. Get The Gavel A weekly SCOTUS explainer newsletter by columnist Kimberly Atkins Stohr. Enter Email Sign Up In all, Massachusetts organizations — including universities, research institutes, and hospitals — received $3.5 billion in funding from the National Institutes of Health. Massachusetts-headquartered companies raised $3.26 billion in venture capital funding. Among all drugs in the development pipeline in the United States, 15 percent were being made by companies headquartered in Massachusetts. But actions taken by President Trump and his administration — cutting funding for scientific research and universities, flirting with tariffs, fanning skepticism about vaccines — threaten to devastate the ecosystem. Today, the industry is at a precipice, and uncertainty abounds. Some companies are already feeling the pinch of terminated federal grants, while others are anxious about what might come. Taken together, Trump's policies could force some companies and scientists to take their money, talents, and products overseas. Advertisement Christopher Locher, CEO of Lowell-based Versatope Therapeutics, which develops a platform to deliver vaccines and therapeutics, said he worries the Greater Boston life sciences ecosystem is 'being flushed down the toilet.' For example, Trump is Trump's funding cuts are already having a large impact on some local companies. Part of the problem is the Trump administration isn't only cutting funding, but it's picking which technologies to fund — in some cases apparently based on politics more than science. Take flu vaccines. The Trump administration recently announced a $500 million campaign to fund the development of a universal flu vaccine, which doesn't require annual updates, using technology being worked on But simultaneously, he cut funding for other work on a universal flu vaccine. Versatope Therapeutics got $14 million in NIH funding and spent five years developing a universal flu vaccine. It had approval from the US Food and Drug Administration to begin clinical trials when Trump terminated the contract's remaining $8 million, with the reason given being 'convenience,' Locher said. Trump also Advertisement Company executives say decisions by Trump officials to disinvest in vaccine-related technology — and concerns about whether government will approve new technology — means it's nearly impossible to find private investment funding to replace lost federal dollars. 'We're faced with bankruptcy in the very near future,' Locher said. Ironically, given Trump's stated commitment to bringing businesses back to the United States, one potential option Locher is eyeing is opening a subsidiary abroad. Conducting clinical trials would be cheaper in another country, whether in Europe, Australia, or China, Locher said, and some countries are offering financial incentives to American companies to relocate. Companies also face a potential workforce brain drain. There have been MassBio officials said China has less rigorous — but faster — safety and research protocols than the US. Australia allows a faster timeline for clinical trials. If regulatory approval of medicines is held up because the FDA is understaffed, companies may seek European regulatory approval instead. The loss of talent to foreign countries will be compounded if the pipeline of local university graduates dries up. One draw for life sciences companies to Boston/Cambridge is the presence of elite schools like Harvard and MIT, with their potential for faculty collaboration and skilled graduates. Advertisement Trump is trying to Chip Clark, CEO at Vibrant Biomedicines in Cambridge, said cuts to university research funding both 'shrink the pipeline of great ideas' that form the basis for many biotech startups and translate to fewer available scientists. Clark said the administration's policies 'seem like a deliberate attempt to try to cede scientific leadership to Europe and Japan and Korea and China. ... They will be delighted to capitalize on our talent, technology, and investment capital to make their robust biotech sectors grow and ultimately compete successfully against the US industry,' he said. Don Ingber, founding director of the Wyss Institute for Biologically Inspired Engineering at Harvard University, said he has postdocs with US visas applying for jobs in Europe, and others who were accepted to work at Harvard but are going elsewhere. 'The fact that places like Harvard and MIT and American universities are magnets for the best and brightest from around the world is what's driven our technology economy and certainly the Boston/Cambridge ecosystem,' Ingber said. 'With this uncertainty, I fear we'll lose a generation.' Ingber, who was forced to stop work on two government-funded projects on drugs designed to prevent injury from radiation exposure, compared administration policies to 'eating seed corn' needed to grow crops. Advertisement Trump's vendetta will undermine one of the most vibrant state economies in the country and set back American science by years. And it's not just eastern Massachusetts that will pay a price; the entire country will. As Ingber noted, it might take years to see the impact of medicines or technologies that aren't developed because of these shortsighted cuts.
