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.

Divisive Rhetoric

Updated: Nov 18, 2024

In the lead-up to the November 20 Maharashtra Assembly election, Congress leader Rahul Gandhi has once again stirred the political pot with his assertion at a rally in tribal-dominated Nandurbar that the Bharatiya Janata Party (BJP) allegedly insults India’s tribal communities by referring to them as ‘Vanvasi’ rather than ‘Adivasi.’ The distinction, while seemingly semantic, reveals much about the Congress party’s identity politics and its ongoing struggle to recapture its former relevance.


Gandhi further argued that such terminology is part of a wider effort to undermine the dignity of tribals, whom he claims the BJP fails to treat with the respect they deserve. This debate over terminology obscures more substantive issues at hand, namely, the realpolitik of caste-based appeals and the way they shape India’s political landscape. The Constitution of India, after all, makes no reference to ‘Adivasi’ instead using the official term Scheduled Tribes or ‘Anusuchit Janjati.’


The fixation on these terms, largely meaningless in fact echoes the Congress’ long-standing tendency to play identity politics for electoral gain. Rahul Gandhi has, over time, cultivated a reputation for provocative and divisive rhetoric, which he seemingly wields as a strategy to rouse caste-based tensions within India’s complex social fabric.


For years, Congress has leveraged the socio-economic grievances of Dalits, tribals, and backward classes to build a vote-bank that depends on the fragmentation of India’s social fabric. Gandhi’s continued focus on this issue seems designed not to resolve any real grievance, but to stoke divisions. After all, what significance does this distinction truly carry when both terms reflect the same social realities for India’s tribals?


This posture of ‘tribal defender’ is especially rich coming from Gandhi, given his own background. Rahul Gandhi, after all, is of Italian parentage - his mother, Sonia Gandhi, hails from a family of Italian nobility, and his paternal grandfather was a prominent European diplomat. By any stretch, he is far removed from the tribal communities he claims to champion. Does he really believe that someone with no personal ties to India’s tribal populations can claim to be their saviour?


Gandhi’s emphasis on ‘indigenous’ populations overlooks the complex history of India’s tribal communities. The Aryan Invasion theory, once widely accepted, has been debunked by a number of modern historians and geneticists, who have shown that India’s population evolved over millennia without a distinct ‘invasion.’ Persisting with the ‘indigenous vs. foreign’ narrative is not only historically flawed but a divisive strategy that risks alienating broad segments of India’s diverse population. Gandhi’s focus on caste politics appears designed to fracture the Hindu vote and win back Dalits, tribals, and backward classes. In the end, debates like ‘Vanvasi’ vs. ‘Adivasi’ are storms-in-a-teacup, with Gandhi’s fixation on it distracting from the real economic and social issues facing marginalized communities. Ultimately, this reliance on identity politics underscores the Congress’s failure to craft a unifying narrative for India’s future.
