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.

For the first time, starting July 1, people in the US will be able to access GLP-1 drugs for weight loss through a new pilot program offered by the federal health insurance program Medicare.

Until now, Medicare covered GLP-1 medications such as Ozempic only for certain conditions like diabetes, but not for weight loss.

The new 18-month Medicare GLP-1 Bridge Program, which will run till the end of 2027, aims to make these high-cost weight-loss medications more accessible to eligible beneficiaries.

According to a KFF analysis of 2023 Part D enrollment data, an estimated 3.8 million Medicare beneficiaries could qualify for the program.

More than 70 per cent of adults in the United States are considered to have obesity or screen as overweight. Studies have proven that GLP-1s are an effective tool in weight reduction, as well as improving other markers of good health, such as blood pressure, lipid profiles, and blood sugar levels.

What Drugs Will Be Covered?

Eligible beneficiaries will be able to access the following GLP-1 weight-loss medications:

• Novo Nordisk's Wegovy injections and tablets
• Eli Lilly's Foundayo tablets
• Eli Lilly's Zepbound KwikPen

The medications will be covered only when prescribed for weight management and when beneficiaries meet the program's medical eligibility criteria.

Who Will Be Eligible?

The program is available only to certain members of Medicare Part D prescription drug plans who want to lose excess weight and maintain weight loss.

Although the program operates outside standard Medicare Part D coverage, beneficiaries can participate only if they are enrolled in:

• An eligible stand-alone Medicare Part D prescription drug plan under Original Medicare, or
• An eligible Medicare Advantage plan that includes prescription drug coverage.

People enrolled in certain less common Medicare plans, including the Program of All-inclusive Care for the Elderly (PACE), may also qualify if they also have a stand-alone Part D plan, Washington Post reported.

According to the Centers for Medicare & Medicaid Services (CMS), most of Medicare's approximately 57 million Part D enrollees are in eligible plans.

However, coverage is not automatic. Providers and pharmacists will identify eligible patients, submit the required forms and obtain prior authorization before treatment can begin. Claims, prior authorization requests and pharmacy payments will be handled by Humana, while Part D plans will not be involved in the process.

How Much Will It Cost?

Eligible beneficiaries will pay a $50 monthly copay for the covered medications.

However, because the program operates outside Medicare Part D coverage:

• The $50 copay will not count toward a beneficiary's Part D deductible.
• It also will not count toward the 2026 Part D annual out-of-pocket spending cap of $2,100.
• The copay is not eligible for the Medicare Prescription Payment Plan, which allows beneficiaries to spread prescription drug costs throughout the year.

What Happens After 2027?

The pilot program is temporary and is scheduled to end in December 2027, unless it is extended.

"It's certainly good news for Medicare beneficiaries who have been essentially shut out of the market for GLP-1s for weight loss if they wanted to use insurance coverage. However, it is a temporary program. It is not a permanent change in Medicare coverage," said Juliette Cubanski, Vice President and Director of Medicare Policy at KFF.

If the program is not extended, beneficiaries who rely on the medications may have to pay higher out-of-pocket prices or discontinue treatment beginning in January 2028, which experts said could lead to weight regain based on current GLP-1 therapies, the Post reported.

A recent study has found that a modified form of vitamin B12 therapy may prove to be a new and promising way to treat glioblastoma, one of the most aggressive forms of brain cancer.

With limited treatment options, patients are usually treated with surgery, radiation therapy, and chemotherapy. Usually, the chance of survival is not bright after diagnosis.

New Vitamin B-12 Compound Shows Promise In Glioblastoma Treatment

Published in the journal Oncoscience, the research study is based on nitrosylcobalamin (NO-Cbl), a vitamin B12-based compound that contains and slowly releases nitric oxide.

The main purpose of the study was to find out whether the vitamin B-12 compound could cross the blood-brain barrier, a protective layer that prevents many medicines from reaching the brain and directly targeting glioblastoma tumors.

The blood-brain barrier is one of the biggest challenges in treating glioblastoma, as it protects the brain from harmful substances, blocking many cancer drugs from reaching tumor tissue.

About The Study

The researchers examined how NO-Cbl affected different types of cancer cells, particularly how it moved through the body of rats with glioblastoma. The results showed that NO-Cbl had an anti-cancer effect on several types of tumors.

Most importantly, the compound was able to cross the blood-brain barrier and accumulate inside glioblastoma tumors in animal studies.

Researchers also found that the compound remained active in tumor tissue for at least 24 hours, delivering nitric oxide directly to cancer cells without affecting normal tissues.

They also tested NO-Cbl in combination with two existing glioblastoma treatments: temozolomide, the standard chemotherapy drug for the disease, and TRAIL, an experimental cancer therapy.

In laboratory-grown glioblastoma cells, the combinations alleviated cancer cell growth much more effectively than any of the treatments used on their own.

About Glioblastoma

A glioblastoma is a fast-growing glioma, a type of tumor that stems from glial cells, which protect nerve cells in the brain and spinal cord.

Glioblastoma can occur at any age but is more commonly found in older adults. The average age at diagnosis is 64.

Public figures among those afflicted include former President Joe Biden's son, Beau Biden, who succumbed to this cancer in 2015. John McCain also passed away in 2018 due to glioblastoma.

According to the MD Anderson Cancer Center, around 12,000 glioblastoma cases are diagnosed in the United States every year. All glioblastomas are grade IV brain tumors, meaning they contain the most abnormal looking cells and are the most aggressive.

About 13,000 Americans are diagnosed with glioblastoma each year, accounting for almost half of all cancerous brain tumors, according to the Cleveland Clinic. More than 10,000 people in the U.S. will succumb to the disease every year, the National Brain Tumor Society reports.

In the light of limited treatment options for glioblastoma, this study is a ray of hope as it shows promise in slowing down the growth of cancer cells by overcoming challenges like treatment resistance.

Heart failure (HF) remains a major global health challenge, affecting more than 64 million adults worldwide.

To improve how the condition is prevented, diagnosed and managed, leading cardiovascular organizations, including the American Heart Association (AHA) and the American College of Cardiology (ACC), have released the "Second Universal Definition of Heart Failure."

The updated definition addresses changes in disease manifestations, diagnostic strategies and the understanding of heart failure's underlying biology. It also aims to establish a unified framework for clinicians, researchers, health systems and policymakers worldwide.

Published on behalf of the ACC, AHA, European Society of Cardiology (ESC) and World Heart Federation (WHF), in collaboration with the Heart Failure Society of America (HFSA), the Heart Failure Association (HFA) of the ESC and the Japanese Heart Failure Society (JHFS), the document updates the First Universal Definition of Heart Failure, released in 2021. It has been published simultaneously in Circulation, Journal of the American College of Cardiology (JACC), European Heart Journal and Global Heart.

What Does The Updated Definition Include?

The prevalence of heart failure continues to rise due to ageing populations and increasing rates of obesity, Type 2 diabetes and high blood pressure.

To better address this growing burden, the new framework introduces several important changes.

• Universal classification of heart failure causes:

• Moving beyond rigid ejection fraction cut-offs:

• Greater emphasis on early detection:

• Recognition that heart failure is dynamic:

• Attention to social and global factors:

Why The New Definition Matters

The revised definition provides a common framework for clinicians, researchers, health systems and policymakers worldwide, helping standardize diagnosis, strengthen research and support more personalized care.

The consensus document will also serve as the foundation for the upcoming American Heart Association/American College of Cardiology Heart Failure Guideline, expected to be published in late 2027.

"Heart failure remains a major challenge that continues to grow globally, and inconsistencies in how it is defined have limited progress in research and treatment. This updated definition provides a clearer, more consistent framework to help clinicians identify risk earlier and guide more personalized treatment approaches that can help improve patient outcomes worldwide," said Mary Norine Walsh, co-chair of the consensus document.

"The new framework recognizes that heart failure is not a static condition. By focusing on stages of disease, underlying causes and disease trajectories—including improvement, remission and recovery—we can better tailor care and advance prevention efforts," she added.
