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.

Hollow Unity

For a country that styles itself the world’s largest democracy, India certainly needs a robust Opposition. In theory, the coming together of parties in the INDIA bloc should be cause for optimism. A chorus of dissent if disciplined, credible and rooted in evidence, can check the excesses of any government. But the noisy march to the Election Commission (EC) office in Delhi was no such moment of principled defiance. It was a performance staged for the cameras and propelled less by democratic conviction than by political opportunism.


In its first major street protest since the 2024 general election, the motley coalition of Congress, Samajwadi Party, Trinamool Congress, the Left and others rallied against the EC’s ‘special intensive revision’ (SIR) of Bihar’s electoral rolls, as well as alleged “vote chori” in the Lok Sabha polls. Some 300 placard-waving MPs in colour-coded party caps marched to NirvachanSadan, clambering over police barricades and shouted slogans before being detained in theatrical fashion before being released two hours later.


It was an arresting spectacle. But what lay beneath the noise was depressingly hollow. Rahul Gandhi, Leader of the Opposition in the Lok Sabha, treated the episode as a veritable ‘coronation moment’ in proclaiming that this was a “fight for the Constitution” and “one man, one vote.” Without verifiable evidence, such slogans ring as tinny as a cracked cymbal.


The EC has already dismissed Gandhi’s allegations as baseless and misleading. Far from engaging with the charges in good faith, the Opposition leaders have sidestepped the Commission’s request to file formal complaints with documentary proof under oath. Officials from Karnataka, Maharashtra and Haryana even wrote to Gandhi personally, inviting him to submit evidence. The invitation remains unanswered.


This is not the conduct of a movement genuinely invested in reforming India’s electoral machinery. It is the choreography of an Opposition that has been listless for months, suddenly discovering that street theatre can mask the absence of a credible legislative or policy alternative. By framing the protest as a moral crusade, Gandhi also sought to elbow out other contenders for leadership within the rickety INDIA bloc while banking on images of hand-holding solidarity to restore the Congress’s waning primacy.


Unity in the Opposition is, in principle, a public good. But unity forged in opportunism, and directed at phantom grievances, corrodes democratic discourse rather than strengthening it. The more the bloc resorts to noisy but evidence-free allegations, the more it invites the government to dismiss legitimate concerns in future as mere political posturing.


Such antics may briefly dominate television coverage, but they do little to inspire confidence in the Opposition’s capacity to govern should it ever return to power. That it was the INDIA bloc’s first real show of unity only underlines how little binds its members beyond the shared hope of dislodging the BJP. The Opposition’s tragedy is not that it lacks causes worth fighting for but that it repeatedly squanders its energy on causes that collapse under scrutiny.
