Cold wave triggers spike in cardiac arrests

Mumbai : As winter temperatures go for a spin across the country, hospitals are witnessing a significant surge of around 25-30 pc in cardiac emergencies, a top cardiologist said.   According to Interventional Cardiologist Dr. Hemant Khemani of Apex Group of Hospitals, cold air directly affects how the heart functions.   “Low temperatures make blood vessels tighten.

Cold wave triggers spike in cardiac arrests

Mumbai : As winter temperatures go for a spin across the country, hospitals are witnessing a significant surge of around 25-30 pc in cardiac emergencies, a top cardiologist said.   According to Interventional Cardiologist Dr. Hemant Khemani of Apex Group of Hospitals, cold air directly affects how the heart functions.   “Low temperatures make blood vessels tighten. When the arteries narrow, blood pressure shoots up and the heart has to work harder to push the blood through the stiffened vessels,” said Dr. Khemani.   Elaborating on the direct effects of cold air on heart functioning, he said that low temperatures make blood vessels tighten, when arteries narrow, blood pressure shoots up and the heart must work harder to push blood through stiffened vessels.   Winter also thickens the blood, increasing the likelihood of clot formation and these combined effects create a dangerous ‘demand-supply mismatch’ for oxygen, especially in people with existing heart conditions.   This trend has caused concern among cardiologists as it adds to India’s already heavy cardiovascular diseases burden – with nearly one in four deaths linked to heart and blood vessel problems.   Dr. Khemani said that sudden temperature transitions - from warm rooms to chilly outdoors - can put additional strain on the heart and risks. “This abrupt shift loads the cardiovascular system quickly, raising the risk of a sudden (cardiac) event among vulnerable individuals.”   Lifestyle Patterns Added to these are the changes in lifestyle patterns during winter month that further amplify the danger. Most people reduce physical activities, eat richer foods, and often gain weight all of which combine to raise cholesterol levels, disrupt blood-sugar balance and push up blood pressure.   Complicating matters for the heart are the social gatherings during the cold season that tends to bring higher intake of smoking and alcohol, said Dr. Khemani.   Recommending basic preventive measures, Dr. Khemani said the chest, neck and hands must be kept warm to prevent heat loss, maintain a steady body temperature and reduce the chances of sudden blood pressure spikes, a low-salt diet, home-cooked meals, shot indoor walks post-eating, adequate hydration and at least seven hours of sleep.   He warns against ignoring warning signals such as chest discomfort, breathlessness, unexplained fatigue, or sudden sweating, pointing out that “early medical care can significantly limit heart damage and improve survival.”   The rise in winter heart risks is not unique to India and even global health agencies like World Health Federation and World Health Organisation report similar patterns.   The WHF estimates that more than 20 million people die of heart-related causes each year - equal to one life lost every 1.5 seconds, and the WHO has listed heart disease as the world’s leading cause of death for five consecutive years.   Seniors affected more by winter chills  Cold weather can hit the heart at any age, but the risk is noticeably higher for men aged above  45 and in women after 55, with the highest danger curve in people over 60, and elders with co-morbidities and history of heart diseases.   “People with existing cardiac problems face greater trouble in winter as the heart has to work harder. Even those without known heart disease can sometimes experience winter heart attacks, as chilly conditions may expose hidden blockages or trigger problems due to sudden exertion, heavy meals, smoking or dehydration,” Dr. Khemani told  ‘ The Perfect Voice’ .   However, contrary to perceptions, cold-weather heart issues have no connection to the COVID-19 vaccine, nor is there any scientific evidence linking the two, he assured.

The Diplomat at the Heart of the Indo-Canadian Schism

Updated: Oct 30, 2024

Sanjay Kumar Verma

The story of Sanjay Kumar Verma, hitherto India’s high commissioner to Canada until his abrupt recall, reveals more than a tale of a diplomat caught in a crossfire of geopolitical tension. His journey embodies the complex, often dangerous balance Indian diplomats must maintain as representatives of the world’s largest democracy.


As Indo-Canadian relations hit rock bottom, Verma’s story captures an extraordinary chapter: an attack by extremists in Alberta, accusations of involvement in a murder case, and a rapidly souring relationship between two nations that once shared a vision for mutual progress.


Born in 1965, Verma had a brilliant academic record, overcoming the challenges of a modest background. He graduated from Patna University before pursuing a postgraduate degree in Physics at IIT Delhi. His diplomatic career began in the late eighties, when he joined the Indian Foreign Service. Over the years, he would gain experience in some of the world’s most culturally complex environments. Starting in Hong Kong, he later served in embassies across China, Vietnam, and Turkiye before becoming the Consul General in Milan and, subsequently, India’s Ambassador to Sudan. His ascent through the ranks continued, with stints in Tokyo and the Marshall Islands, before culminating in his role as High Commissioner to Canada.


In Canada, however, Verma found himself on unexpectedly turbulent terrain. India and Canada have long shared a diplomatic relationship that has oscillated between cooperation and contention. Historically, both countries found common ground in their shared status as former British colonies and members of the Commonwealth. The bilateral ties deepened during the early years of Indian independence, as Canada extended development aid to India and welcomed Indian immigrants, who went on to become a vital part of the Canadian multicultural fabric. However, relations strained in the 1980s as Canada became a hub for Sikh separatist movements, especially the Khalistan movement. This tension escalated with the tragic 1985 Air India Flight 182 bombing, which killed 329 people and cast a lasting shadow over bilateral relations.


Indian leaders have voiced frustration over Canada’s perceived leniency toward secessionist groups. Diplomatic exchanges, including those between Verma and Canadian officials, highlight unresolved grievances and new tensions on both sides.


Just before his recall, Verma recounted a harrowing experience of being surrounded and nearly attacked by a group of Khalistani extremists wielding what he identified as a sword and which was distinctly different from the kirpan, a Sikh religious symbol. The ambush took place outside an event meant to foster cultural and business ties between Indians and Canadians. “It came to within inches of my body,” he recalled in a recent interview, describing how local police pushed the crowd back only after they had encircled him.

His wife was by his side, and their alarm was shared by the small contingent of security officers who, perhaps like Verma, had underestimated the reach of hostility.


Verma’s tenure in Canada was marked by his increasingly vocal stance on the plight of Indian students—a population exceeding 300,000—caught, he claimed, in the allure of anti-India extremism caused by economic hardship and ideological manipulation.


His removal from Canada is underscored by Ottawa’s recent claims that Verma was linked to the investigation of Hardeep Singh Nijjar’s killing, a designated terrorist in India. Ottawa’s accusations, first articulated in a pointed speech by Canadian Prime Minister Justin Trudeau, suggested “credible allegations” of Indian involvement, further implicating Verma. India responded swiftly, rejecting the claims as “absurd” and “motivated,” a sentiment echoed by Verma, who dismissed the allegations as a “political farce.”


Despite these exchanges, Verma’s intentions in Canada remained rooted, as he put it, in preserving diplomatic dialogue. But the recall laid bare India’s contention that Canada has provided undue space to anti-India elements under the guise of freedom of speech and assembly—a freedom that, in Verma’s experience, came too close for comfort.


As he returned to Delhi, Verma appeared keenly aware that the bridge between Ottawa and New Delhi would be a difficult one to rebuild. In a final appeal, he expressed a hope that both nations could “restore” a once-promising relationship.
