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.

Humble Colossus

Updated: Oct 22, 2024

Ratan Tata, who passed away at 86, was a man who spoke in the measured tones of a diplomat and moved with the quiet grace of a statesman. His impact on India’s industrial landscape was seismic. He wasn’t one for bombast, despite commanding one of the world’s most sprawling conglomerates. This reserved and unassuming leader of the Tata Group led with a sense of dignity and responsibility that increasingly feels like a relic of another age. His death marks not just the proverbial end of an era but the departure of a figure whose rare combination of ambition and humility is difficult to imagine being replicated.


For four decades, Tata guided his family’s company through turbulent waters, not only expanding its reach but redefining what it meant to be an Indian multinational in a globalized world. In the 1990s, as India underwent economic liberalization, many business leaders were uncertain about handling the surge of foreign competition. But Tata saw a different horizon. His acquisitions - Tetley Tea, Corus Steel, and the crown jewel, Jaguar Land Rover - were statements of intent. It proved that India was not just opening its doors to the world, but was ready to claim a seat at the table.


Ratan Tata’s ascent to the helm of Tata Group in 1991 marked a turning point for the group’s business. He transformed the centuries-old, largely domestic conglomerate into a global titan, shaping both the company and India’s economic history Yet, unlike many of his contemporaries, Tata did not appear to lust after power or wealth for its own sake. He understood that the true measure of a corporation was not just its profits, but its purpose.


This sense of corporate responsibility permeated the Tata Group under his stewardship. The Tata trusts, which control a significant portion of the conglomerate, were channelled into education, healthcare and social welfare, long before such initiatives became de rigueur among global corporations. Ratan Tata’s vision of business extended beyond immediate returns. He did not just want to make money - he wanted to build a better India.


In a country where corruption often festers in the corridors of business and politics, Tata stood apart. He was, by all accounts, incorruptible. His refusal to bow to the demands for bribes in the early days of his airline venture was one of the more publicized examples of his moral code, but it was emblematic of a larger ethos that shaped the Tata Group. In the often-unscrupulous world of Indian business, where backroom deals and political patronage are part of the game, Tata’s integrity was legendary. He was a man who did not waver, even when it would have been easier to compromise. His legacy will not be found in gilded skyscrapers or flashy acquisitions, but in the livelihoods improved by Tata’s social initiatives, in the global respect won for Indian business, and in the ideals of corporate governance he upheld until the very end.
