Heart disease is often linked to high cholesterol, obesity, or lack of exercise. However, there is mounting evidence that suggests that mental health plays a crucial role in cardiovascular well-being. Stress, anxiety, and depression can silently strain the heart, increasing the risk of serious complications.
A recent study, published in Nature Human Behaviour, showed that loneliness has a significant impact on proteins present in a person's blood. For the study, researchers used data from more than 42,000 participants to explore whether the 9.3% who reported social isolation and 6.4% who reported loneliness had different levels of proteins in their blood compared with those who did not. The researchers then studied data that tracked the health of participants over an average 14-year period.
"We found around 90% of these proteins are linked to the risk of mortality," Dr Chun Shen, Fudan University in China, who is also the lead researcher said. "In addition, about 50% of the proteins were linked to cardiovascular disease, type 2 diabetes and stroke," he added.
Dr Shrey Kumar Srivastav, senior consultant at Sharda Hospital, said that subtle symptoms of heart disease, such as fatigue, shortness of breath, swelling in the lower legs, dizziness, and jaw pain, are often overlooked or attributed to stress and ageing. "Women, in particular, may experience atypical signs like extreme fatigue, indigestion, or upper abdominal pain instead of classic chest pain, leading to delayed diagnosis," he added.
Can Mental Health Issues Trigger Heart Diseases?
Chronic stress can trigger harmful cardiovascular effects, including elevated blood pressure, increased heart rate, and inflammation—key contributors to heart disease. Anxiety and depression further impact heart health by disrupting sleep patterns, raising stress hormone levels, and encouraging unhealthy habits like poor diet and inactivity.
Mental health issues like depression and anxiety have a profound impact on the heart. They don’t just affect emotions but can increase inflammation and put extra strain on the cardiovascular system, warns Dr Srivastav.
Certain risk factors, such as obesity and diabetes, disproportionately affect women, making them more vulnerable to heart failure with preserved ejection fraction (HFpEF). However, due to gender-specific symptom variations, heart disease in women often goes undiagnosed for longer.
Obesity is more prevalent in women than men and is a major risk factor for heart failure. Diabetes, too, has a greater impact on women’s heart health, yet diagnosis and treatment delays are common. Addressing this gap requires increasing awareness, training healthcare providers, and promoting early diagnostic tools,” explains Dr Srivastav.
How Can You Protect Your Heart?
A simple yet effective way to support heart health is by committing to a brisk 30-minute walk daily. Walking not only helps regulate blood pressure and manage weight but also improves circulation and reduces stress.
"Regular physical activity, paired with a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins, significantly lowers cardiovascular risks," advises Dr Srivastav.
Heart disease can often go undetected until a major event occurs, making routine screenings essential.
- For women: Begin screenings around age 30 and continue with regular checkups.
- For men: Start screenings at age 35.
Health screenings, including blood pressure checks, cholesterol tests, and electrocardiograms (ECGs), are critical for early detection of silent heart conditions.

90s star Samuel Monroe Jr., best known for his role in the 1993 film Menace II Society, remains critically ill in a Los Angeles hospital. His family is now facing the possibility that he may end up in a vegetative state.
According to the latest update shared by his wife, Shawna Stewart, Monroe is in a medically induced coma and remains on life support.
Doctors have said that he could ultimately be left in that life state as complications in his brain continue to worsen.
Samuel's health crisis reportedly began with meningitis. Stewart previously said he contracted the infection while filming in Las Vegas around 18 months before his hospitalization, but the illness was repeatedly misdiagnosed.
“Because of this negligence, the meningitis went untreated for eight months,” Stewart said. She also said that by the time it was diagnosed, the infection had spread to his spine and brain.
His condition later became more complicated after he developed MRSA pneumonia, a serious infection caused by methicillin-resistant Staphylococcus aureus. He needed life support, dialysis, and multiple blood transfusions for several months.
There was some improvement in his health in May. His kidney function improved enough for doctors to stop dialysis; he was taken off blood-pressure medication and was able to breathe without a ventilator for about four hours.
He was also reportedly alert and well enough to answer questions by moving his head. But that phase did not last.

A vegetative state is different from a coma, although both involve severe impairment of consciousness.
A person in a vegetative state may have periods of wakefulness, like opening their eyes, but may not show any sign of awareness of themselves or their surroundings. Basic functions like breathing and sleep-wake cycles can continue.
Importantly, doctors cannot determine an individual's neurological outcome from one symptom alone. The extent and location of brain injury, neurological examinations and repeated imaging, and other assessments are considered.

Stewart told TMZ that Monroe’s brain continues to swell and that his brain ventricles have enlarged and are struggling to properly contain cerebral fluid. The pressure and complications in his brain have triggered seizures.
Monroe has undergone three brain surgeries, while his left lung has also partially collapsed. Doctors are continuing to perform CT scans to assess his brain activity and condition.
Brain swelling is particularly dangerous as the skull is a rigid body part. When fluid or swelling increases inside it, pressure can rise and potentially damage brain tissue.
Severe or prolonged swelling can affect consciousness, movement, communication, and other essential neurological functions.
According to reports, Monroe’s family is not making an immediate decision about his life support.
Stewart said the family has agreed to wait for three or four more CT scans before making a decision. Depending on those scans, the family may have to take the decision of withdrawing life support.

In a major scientific breakthrough, researchers at Stanford University have used artificial intelligence (AI) to design entirely new viruses that do not exist in nature.
The AI-generated viruses successfully killed Escherichia coli (E. coli) bacteria that had become resistant to naturally occurring bacteriophages (phages)—viruses that infect and destroy bacteria—offering new hope for tackling antibiotic-resistant infections.
The study, published in the journal Science, also raises important biosafety concerns, as the same technology could potentially be misused to design harmful pathogens.
Chemical engineer Brian Hie and bioengineering graduate student Samuel King developed Evo 2, a generative AI model capable of writing complete DNA sequences and designing entirely new genomes.
The researchers focused on bacteriophages, viruses that infect bacteria and are already being explored as alternatives to antibiotics for treating difficult bacterial infections.
Using genomes designed by Evo 2, the team synthesized nearly 300 novel phages and tested them against E. coli. From these, they identified 16 highly effective phages that successfully killed bacteria resistant to naturally occurring phages.
The researchers believe the ability to rapidly design customized phages could transform phage therapy and expand the arsenal against antibiotic-resistant bacteria.
The team redesigned bacteriophage ΦX174, one of the simplest known viruses. Despite its small size, ΦX174 efficiently infects and kills bacteria, making it a valuable model for developing new phage therapies.
One of the biggest challenges in infectious disease treatment is that bacteria eventually develop resistance to antibiotics—and even to individual phages. To overcome this, the researchers designed a genetically diverse cocktail of 16 AI-created phages.
"If the bacteria gain resistance to a single phage, it's game over for the medication," Hie said. "But if you have multiple genetically distinct phages in a mixture, it would be harder for the bacteria to develop resistance to the entire cocktail."
The team showed that the phage cocktail successfully eliminated E. coli strains that had become resistant to the natural ΦX174 virus.
"We have a proof of concept in the paper, where we show that this cocktail of 16 phages rapidly overcomes resistance in E. coli that is immune to native ΦX174," Hie said.
Researchers believe the same AI-driven approach could eventually be used to develop phages against other drug-resistant bacteria, including:
If successful, AI-designed phage cocktails could provide a powerful alternative to conventional antibiotics, whose effectiveness continues to decline because of antimicrobial resistance.
The researchers have made Evo 2 freely available as open-source software, allowing scientists around the world to design and study new genomes.
While this could accelerate advances in medicine and biotechnology, experts say it also highlights the urgent need for stronger oversight.
"The ability to compose viral genomes using generative AI now exists; the governance to safely steer it does not," wrote Prof. Tom Inglesby and Dr. Moritz Hanke of the Center for Health Security at Johns Hopkins University in an accompanying Science commentary.
Tom Ellis, Professor of Synthetic Genome Engineering at Imperial College London, described the research as impressive but cautioned that AI could theoretically be used to design harmful viruses if trained on the genetic code of dangerous pathogens, The Guardian reported.
However, he said safeguards—such as restricting access to sensitive genetic data and screening synthetic genomes before they are manufactured—could help reduce those risks.

The Donald Trump administration is reportedly considering an executive order focused on the US childhood vaccination schedule and autism research, despite decades of scientific evidence showing no link between vaccines and autism.
According to a Washington Post report citing official sources, the proposed order would examine the childhood immunization schedule and autism research. However, its scope and timing have not been finalized and could still change.
The move comes even as some of Trump's political advisers have reportedly warned that elevating the issue could hurt Republican candidates ahead of the November midterm elections.
According to The Wall Street Journal, Trump wants "alleviating autism" to become part of his presidential legacy and has privately expressed frustration that US Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. has not gone far enough in reducing the recommended childhood vaccination schedule. The report also said Trump believes that reducing the number of recommended childhood vaccines could lower autism rates.
In recent months, Trump has urged senior administration officials, including Kennedy Jr., to increase scrutiny of childhood vaccines.
Last year, Kennedy had cancelled roughly $500 million in mRNA vaccine research grants and replaced every member of a federal immunization advisory panel. However, he has been relatively quiet on vaccine policy this year after White House aides reportedly advised that vaccine skepticism was unpopular with many voters.
Medical experts continue to emphasize that extensive research has found no evidence that vaccines cause autism.
"Donald Trump has been anti-vaccine at least since 2015," Dr. Paul Offit, Director of the Vaccine Education Center and an infectious disease specialist at Children's Hospital of Philadelphia, was quoted as saying by CNN.
During the 2015 Republican primary debate, Trump claimed autism had gotten "totally out of control" and suggested vaccines should be administered in "smaller doses over a longer period of time."
Trump has repeatedly suggested there may be a connection between vaccines and autism, despite overwhelming scientific evidence disproving the claim. He has also argued that the US childhood vaccination schedule should be reduced, raising concerns among public health experts.
"I believe in vaccines, but I don't believe that, you know, you have to have a mandate for all of them," Trump said in a May interview with journalist Sharyl Attkisson. "I really feel that vaccines, if they were given in smaller quantities—they want to cut some out, and that's good, too. I agree with that."
Multiple large-scale studies conducted over the past two decades have consistently found no causal link between childhood vaccines—including the MMR vaccine—and autism spectrum disorder.
Major health organizations, including the World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC), continue to recommend routine childhood immunization as one of the safest and most effective ways to prevent infectious diseases.
