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.

As the true number of COVID-19 cases and deaths is believed to be higher than reported, a new study suggests that the actual toll of long COVID may also double than the current estimates.
The research, led by Mass General Brigham, found that many long COVID cases remain hidden because current surveillance systems rely heavily on diagnostic codes that fail to capture a large number of patients.
Using a novel AI algorithm, researchers analyzed medical records of nearly 460,000 COVID-19 patients across 58 hospitals in the United States. The findings showed that approximately one in six people — around 16 per cent — developed long COVID, translating to more than 18 million Americans.
The figures are nearly double current estimates and highlight the growing burden of chronic health conditions following COVID-19 infection. The study was published in JAMA Network Open.
“Over 10 million people with long COVID would go entirely undetected by the diagnostic code that health systems and policymakers rely on to track the disease burden,” said corresponding author Hossein Estiri, a faculty member in the Mass General Brigham Department of Medicine.
“The figures we uncovered are almost certainly an undercount,” he added.
Researchers noted that current diagnostic coding systems, including the ICD code U09.9 for post-COVID conditions, identify fewer than 7 per cent of long COVID patients.

The study analyzed electronic health records from 457,950 patients who had previously tested positive for COVID-19 across four US regions — New England, Southeast Texas, Southern California and Western Pennsylvania.
Overall, 16.3 per cent of patients were identified with long COVID, with regional rates ranging from 13.6 per cent to 22.7 per cent.
The researchers also found significant regional differences in long COVID symptoms and related conditions, including varying rates of prediabetes, which is emerging as a possible long-term effect of COVID-19.
The study authors noted that undocumented infections — which became more common after widespread testing declined — were not included in the analysis. Patients without long-term medical records were also excluded, suggesting the actual burden of long COVID could be even higher.
“These patients are not absent from clinical care; they are absent from the diagnostic code that would identify them as long COVID patients,” said lead author Jiazi Tian, a data scientist in the Clinical Augmented Intelligence Group at Mass General Brigham.
“The cardiologist seeing new dysautonomia, the endocrinologist seeing new metabolic disease, the neurologist seeing unexplained cognitive complaints — some of these presentations are long COVID arriving without the label that would connect them to a COVID-19 infection,” Tian added.

Long COVID refers to symptoms that continue for three months or longer after the initial COVID-19 infection.
Common symptoms include:
Researchers say many long COVID conditions are still being studied, and some people may experience multiple symptoms at the same time.

US President Donald Trump this week underwent his third annual medical check-up during his second term and declared that it went “perfectly well”.
Trump, who turns 80 next month, visited the Walter Reed National Military Medical Center for a routine health examination on May 26. The medical check-up, conducted after about 13 months, reportedly lasted around 3.5 hours.
“Everything checked out PERFECTLY,” Trump wrote on social media.
However, neither Trump nor the White House has disclosed detailed medical findings, leading to renewed speculation about the health of the oldest American President.
The concerns come amid visible signs of deterioration observed during several public appearances. These include persistent bruising on his hands, micro naps during public meetings, slurred speech, and frequent factual mix-ups — all of which have raised questions about whether information regarding his health is being withheld.
The White House had earlier explained that the bruises on Trump’s hands were caused by “frequent handshaking” combined with aspirin use.
Doctors have also speculated that his slurred speech may indicate signs of a recent stroke.
Dr. Bruce Davidson, a professor at Washington State University’s Elson S. Floyd College of Medicine, discussed the issue during an appearance on The Daily Beast podcast. He said his interpretation was based on observing Trump’s physical behavior and speech patterns over time.
“Earlier in the year, there was video of him shuffling, and I thought that was weird,” he said on the podcast.
He suggested that such movement patterns can sometimes be seen in patients recovering from strokes.
Despite the speculation, Trump has continued to defend his mental sharpness and cognitive abilities.
“So I’ve taken (a cognitive test), and I’ve aced it all three times, I’ll tell you, because it is a positive thing,” Trump said. “It starts off with an easy question. And by the time you get to the middle, it gets tougher.”
According to a White House summary of Trump’s previous annual medical examination in April last year, he was found to be in “excellent cognitive and physical health”.
“A comprehensive neurological examination revealed no abnormalities in his mental status, cranial nerves, motor and sensory functions, reflexes, gait, and balance. Cognitive function, assessed using the Montreal Cognitive Assessment (MoCA), was normal with a score of 30 out of 30,” White House physician Captain Sean Barbabella wrote.
There were also tests for depression and anxiety, and Trump recorded scores “within the normal range for both,” although exact numbers were not disclosed.
Scans conducted in October also reportedly showed that Trump was in “excellent overall health”.

In a landmark order, the Supreme Court of India has recognized the Right to Trauma Care as an integral part of the Right to Life under Article 21 of the Constitution.
The court issued comprehensive, time-bound directions covering the entire trauma chain of survival — comprising the inter-linked and coordinated chain of survival from the site of injury to definitive hospital care — aiming to strengthen emergency medical response and ensure timely access to trauma care across the country.
The directions, issued in SaveLIFE Foundation & Anr. v. Union of India & Ors., are binding on all 36 States and Union Territories. They cover the full spectrum of traumatic injuries, including:
In its the apex Court stated that “a uniform framework for trauma care, building public awareness, standardization of first aid skills, and proper Good Samaritan laws is required, since the right to trauma care of citizens is an integral part of the right to life enshrined under Article 21 of the Constitution of India.”
India records approximately 4.67 lakh accidental deaths every year from road crashes, falls, burns, drowning, industrial injuries, violence, and disasters.
Of these, road crashes alone account for approximately 1.77 lakh deaths annually. As per the 201st Report of the Law Commission of India, 50 per cent of those killed in road crashes could have been saved had they received timely emergency medical care.
The NITI Aayog-AIIMS Emergency and Injury Care Report (2021) found that at least 30% of all trauma-related deaths in India are attributable to delays in emergency care.
Despite the scale of preventable loss of life, India had no unified, enforceable national trauma care framework. Responses compiled from 34 States and Union Territories and placed before the Court revealed a deeply fragmented system, including inconsistent ambulance standards, unintegrated emergency helplines, absent trauma registries, ungraded hospital facilities, and patchy implementation of centrally mandated schemes.
The petition was filed by SaveLIFE Foundation in October 2024.

The Supreme Court’s directions cover nine domains of the trauma chain of survival. All States and Union Territories are bound by these directions, with compliance to be reported before the Court-appointed monitoring authority.
The Court has also directed that copies of its order be sent to the Chief Secretaries of all States and Union Territories, who are required to submit Action Taken Reports to the Registry of the Supreme Court within the timelines prescribed for each direction.
The matter is expected to be listed after four months for issuance of further directions based on the compliance reports received.
