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.

Unchecked Expansion

The Karnataka Waqf Board’s recent claim over Bidar Fort, a protected monument under the Archaeological Survey of India for over seven decades, has sparked alarm and triggered controversy. This development, compounded by similar land disputes in Maharashtra and Telangana, has ignited tensions across southern India. Citizens, conservation authorities and temple trustees alike are increasingly concerned that the Waqf Board’s expansive reach over public, private, and religious lands might not only disrupt land ownership but also escalate communal divides.


The Bidar Fort, a 15th-century historical landmark, was reclassified as waqf property by the Karnataka Waqf Board in 2005, a move that went largely unnoticed until recently. Local authorities, including Bidar’s deputy commissioner and ASI officers, expressed shock at the board’s assertion, especially since ASI has managed the fort for decades. The Waqf board’s inclusion of Bidar’s historically significant monuments under its jurisdiction has raised serious governance concerns, with authorities confirming they were unaware of such claims. Meanwhile, the Waqf Board has also extended its reach to nearby villages like Dharmapur and Chatnalli in Bidar taluk, marking 26 acres under Survey no. 87 in Dharmapur village. These areas, previously outside the board’s scope, have now been reclassified as waqf properties, causing uncertainty among farmers, schools, and local communities.


The board’s actions in Karnataka are part of a broader trend of similar land claims in other states, including Maharashtra and Telangana. In Maharashtra, the Waqf Board’s assertion over 40 acres surrounding the Kanifnath Temple in Ahmednagar had led to a confrontation with temple trustees, who argue that historical records confirm the land’s ownership by the temple. The dispute has escalated as the Waqf Board has installed signs claiming ownership, intensifying tensions. In Telangana, the Waqf Board’s declaration over 750 acres in Malkajgiri district has frozen property transactions across several residential neighbourhoods, with locals decrying the lack of prior notification.


The Waqf Board’s growing reach has stoked fears that these actions are part of a broader, more politically motivated strategy. Intelligence officials warn that the Waqf Board’s claims over properties, spanning agricultural, temple, and residential lands across Karnataka, Kerala, and Tamil Nadu, could fuel secessionist sentiments. The rise in such disputes has led some to see the Waqf Board’s actions as land-grabbing, disproportionately affecting Hindu and Christian communities in these regions.


The increasing influence of the Waqf Board in land ownership could lead to destabilizing communal and territorial rifts. If left unchecked, the Waqf Board’s expanding power could set a dangerous precedent, challenging property rights and communal harmony. It is imperative for the central and state governments to take swift action to prevent these claims from spiralling into a full-scale political crisis.
