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.

Myocardial infarction (MI) is one of the most common cardiovascular disorders, with an estimated prevalence of 3.8% in individuals aged less than 60 years and 9.5% in those aged over 60 years. MI remains a leading cause of death and is a significant public health concern worldwide.

But a heart attack isn't one single disease with one single mechanism. Being able to classify the type of myocardial infarction quickly can improve diagnosis and treatment.

In view of this, four major cardiac societies—the European Society of Cardiology (ESC), the American College of Cardiology (ACC), the American Heart Association (AHA) and the World Heart Federation (WHF)—have jointly launched the Fifth Universal Definition of Myocardial Infarction.

The Fifth Universal Definition of Myocardial Infarction replaces numerical labels with three clinically meaningful categories.

The new approach aims to help healthcare professionals make more consistent diagnoses and enable patients to understand their condition better.

The new definition also aligns with the International Classification of Diseases (ICD) coding, which captures statistics on the extent, causes and consequences of different diseases.

“People may think of an MI as a heart attack caused by a blocked coronary artery but there are many different causes of MI,” explained ESC Chair, Professor Nicholas Mills from the University of Edinburgh, UK.

“The previous universal definition used a numerical system to categorize the different types of MI but this was not always easy to apply in clinical practice, leading to inconsistencies in diagnosis and treatment. The ESC, ACC, AHA and WHF have worked together to devise an updated and simplified classification system for MI, which aims to address these limitations.”

What Does the Fifth UDMI Mean?

The Fifth Universal Definition of Myocardial Infarction updates the classification to better reflect underlying pathophysiology, align with the clinical evaluation of patients, and incorporate objective diagnostic criteria.

Notably, it could facilitate wider study of less common mechanisms of primary MI, such as spontaneous coronary artery dissection (SCAD), a condition occurring predominantly in women that is currently underdiagnosed.

What Are the 3 New Heart Attack Categories?

The new system considers the underlying cause of MI and aligns the diagnosis with established approaches to clinical evaluation. It recognises that MI occurs in three clinical settings: primary MI, secondary MI and procedure-related MI.

In this updated approach to MI classification, all MIs fit into one of these three clinical categories, and the new document outlines the diagnostic tests and investigations required for each.

1. Primary MI

Primary MI arises spontaneously due to an acute problem in a coronary artery. It is most commonly caused by a rupture of an atherosclerotic plaque, but there are other causes, such as a tear in the coronary wall (spontaneous coronary artery dissection [SCAD]), spasm or a clot.

2. Secondary MI

Secondary MI arises from an imbalance in oxygen supply and demand in the heart caused by another condition, such as very high or very low blood pressure or a very fast heartbeat.

3. Procedure-Related MI

The third setting—procedure-related MI—is one that occurs within 30 days of a cardiac procedure, such as coronary stenting, or a heart operation, such as coronary artery bypass surgery.

“Clinicians often do not use the previous numerical terminology—e.g. type 2 or type 4c—in patient discussions as it is rather complex. With the new approach, we can now talk with patients about the cause of their MI so that they can understand their condition and recognize why the next steps, such as further tests and treatments, are needed,” said ACC/AHA Chair, Professor Kristin Newby from Duke University Medical Center, Durham, US.

US President Donald Trump has announced drug pricing deals with nine more drug makers, including international pharmaceutical companies and smaller biotech firms, as part of his push to make healthcare more affordable.

Currently, US consumers pay nearly three times more for prescription medicines than people in other developed nations. Trump has been pressuring drug makers to bring the prices closer to those paid in other countries.

The latest deals, the White House said in a statement, bring the administration’s total to 26 drug makers. According to Trump, these represent 90% of the domestic pharmaceutical market, while the remaining 10% is “also coming in” and “have no choice.”

Which Companies Signed the Deals?

The latest agreements build on the administration’s broader “most favored nation” (MFN) drug pricing policy.

The White House said the nine companies are:

• Alcon
• Astellas Pharma
• BeOne Medicines
• BridgeBio
• CSL
• Kyowa Kirin
• Sun Pharma
• Teva Pharmaceuticals
• UCB

What Do the Deals Mean?

The White House said the agreements will lower prices on medicines used to treat costly chronic and rare diseases, including hemophilia, Parkinson’s disease, macular degeneration, glaucoma, liver disease, skin conditions and various cancers.

The deals give every state Medicaid program access to MFN prices on products from the nine companies, generating billions of dollars in savings.

The agreements also guarantee MFN pricing for all new innovative medicines the companies bring to market, which the administration says will prevent foreign price controls from benefiting from US pharmaceutical innovation.

$19.6 Billion US Manufacturing Investment

The nine companies have committed to investing at least $19.6 billion collectively in US manufacturing in the near term, according to the White House.

Astellas, Sun Pharma, Teva and UCB also agreed to donate active pharmaceutical ingredients to the federal government’s strategic reserve, known as SAPIR, aimed at reducing reliance on foreign supplies and preparing for emergencies.

Previous Drug Pricing Deals

Over the past year, the administration reached deals with 17 other drug makers, including Pfizer, Eli Lilly and Novo Nordisk.

Novo Nordisk and Eli Lilly reportedly agreed to price cuts in exchange for making their medicines more widely available through Medicare.

Trump also signed an executive order in May 2025 to revive the MFN policy, calling for prices to be increased outside the US and to “end global freeloading.”

The biggest savings from earlier drug pricing deals have come from weight-loss medicines.

Novo Nordisk and Eli Lilly reportedly agreed to price cuts in exchange for making their medicines more widely available through Medicare.

Will Americans Pay Less?

It remains unclear how many medicines are covered by the new deals or how large the discounts will be, making the potential savings for patients and the government difficult to determine.

The White House did not release details of the agreements, while some companies described certain terms as private. The administration and several companies said the deals will also bring future savings on innovative medicines and expand US manufacturing.

Beyond weight-loss drugs, consumer watchdog Public Citizen has questioned how much price relief Americans are actually receiving from the administration’s agreements, Reuters reported.

Medicaid already receives steep discounts from drug makers under existing law, while most Medicaid beneficiaries pay little out of pocket for prescriptions.

A new Indian Council of Medical Research (ICMR) study based on 20 tertiary-care hospitals has found that patients with drug-resistant bacterial infections face higher mortality, longer hospital stays and substantially higher costs of treatment than those infected with drug-sensitive strains. The study analysed nearly 1.6 lakh hospitalised patients between April 2022 and April 2025.

The findings, published in The Lancet Regional Health – Southeast Asia, focused on four major Gram-negative bacteria: E. coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa. Of 26,213 patients with confirmed infections caused by these bacteria, 61.1% had carbapenem-resistant infections.

ICMR Says India Is Facing A 'Superbug' Crisis

The new study found that mortality was consistently higher among patients with carbapenem-resistant infections. For Klebsiella pneumoniae, mortality was 31.2% among patients with resistant infections versus 23.5% among those with susceptible infections.

For E. coli, the figures were 24.4% versus 17.3%. For Acinetobacter baumannii, mortality was 37.9% versus 32.8%, while for Pseudomonas aeruginosa, it was 28.9% versus 20.2%.

The risk was particularly severe with infections that were resistant to carbapenem, where mortality reached 46.4% to 50.8%.

Drug Resistance Also Comes With A Bigger Treatment Cost

The study also found that antibiotic treatment costs were 1.1 to 2 times higher for drug-resistant infections. Treatment of resistant E. coli, for example, averaged $420 per patient, compared with $211 for susceptible infections.

The corresponding costs were $587 versus $505 for K. pneumoniae, $655 versus $436 for A. baumannii, and $702 versus $510 for P. aeruginosa.

Patients also spent longer in hospital. Those with resistant E. coli infections stayed an average of 23.1 days, compared with 17.8 days for susceptible infections.

“AMR Is No Longer A Distant Threat”: ICMR

Dr Kamini Walia, senior scientist at ICMR and an author of the study, said, “Antimicrobial resistance is no longer a distant threat—it is already costing Indian lives.”

She added. “Our study shows that carbapenem-resistant infections carry substantially higher mortality and treatment costs.”

But Walia stressed that simply developing or prescribing stronger antibiotics is not enough. The answer, she said, is “better infection prevention, timely diagnostics and responsible antibiotic use.”

That is important because every time antibiotics are used, susceptible bacteria can be eliminated while resistant ones survive and multiply. Misuse or incomplete or inappropriate treatment can accelerate that process.

Avoid Delay In Treatment

According to The Times of India, Dr Rahul Pandit, a critical care specialist at H N Reliance Hospital said that Mumbai hospitals are also seeing more patients with carbapenem-resistant infections.

“It takes longer to treat a patient with a drug-resistant infection. Developing a culture, identifying the organism and determining its resistance pattern can take a few days, although molecular diagnostics can help us do this faster,” he said.

When the usual antibiotic no longer works, doctors may need to use combinations of drugs or newer, more expensive medicines.

ICMR Has Been Monitoring AMR For Nearly 13 Years

ICMR has been tracking antimicrobial resistance through its Antimicrobial Resistance Surveillance and Research Network (AMRSN) since 2013. The agency says AMR can lead to prolonged illness, higher healthcare costs and increased mortality, while inappropriate antibiotic use remains one of the major challenges.

ICMR's current priorities include strengthening surveillance, improving infection prevention, expanding rapid diagnostics and developing alternative treatments such as bacteriophages and monoclonal antibodies.
