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 Arakan Army: India’s Strategic Ally?

Arakan Army

As Bangladesh grapples with economic challenges and rising radicalism, a new crisis along its Myanmar border is contributing to the chaos. The Arakan Army, a formidable ethnic insurgent group from Myanmar, had recently mounted a significant incursion into Bangladesh’s southern regions, allegedly capturing areas along the border. While the development has alarmed Dhaka, it raises questions about whether this is a fortuitous development or a carefully calculated strategy by India to manage instability in its eastern neighbourhood.


Bangladesh’s internal situation has been deteriorating rapidly ever since the toppling of Sheikh Hasina’s government, which was well-disposed towards India. Economic woes, violent atrocities against minorities, and the radical hostility of Islamist groups — particularly those allegedly aligned with Jamaat-e-Islami and Al-Qaeda — have created a toxic mix. The situation is exacerbated by the leadership of Muhammad Yunus, whose policies are viewed as fostering Islamist sentiments. This environment not only destabilizes Bangladesh but poses a direct threat to India, especially in its border states.


Enter the Arakan Army, an insurgent group that has been steadily gaining ground in Myanmar’s Rakhine State. With its control over vast stretches of the Myanmar-Bangladesh border, the Arakan Army’s rise could serve India’s strategic interests in neutralizing the threats emanating from an increasingly unstable Bangladesh. Reports suggest the Arakan Army has declared its opposition to jihadist groups operating in the region, accusing them of atrocities against Buddhists and Hindus and collusion with international terror networks.


This aligns well with India’s broader security concerns. By supporting or tacitly enabling the Arakan Army’s operations, India could achieve multiple objectives, namely curtailing Islamist extremism.


The Arakan Army’s campaign could weaken the influence of radical groups such as the Rohingya Solidarity Army and Arakan Rohingya Salvation Army, which are reportedly using Bangladeshi soil as a base for operations against India. By bolstering the Arakan Army’s control over the Myanmar-Bangladesh border, India could create a buffer zone that reduces the spillover of jihadist violence into its territory.


A destabilized Bangladesh under Yunus’s leadership makes it harder for India to maintain regional stability. The Arakan Army’s presence could give India leverage to counterbalance any anti-India policies emanating from Dhaka.


Speculation is rife about whether India’s National Security Advisor, Ajit Doval, known for his unconventional strategies, is behind this development. India has long maintained strategic ties with various ethnic armed groups in Myanmar, including the Arakan Army. Given the current geopolitical scenario, it would not be surprising if India were providing covert support—logistical or intelligence—to the Arakan Army as part of a larger game plan to safeguard its eastern flank.


Doval’s focus has often been on pre-emptively neutralizing threats rather than reacting to them. Supporting the Arakan Army fits this modus operandi. It allows India to weaken Islamist networks without direct intervention, keeping its hands ostensibly clean while achieving strategic goals.


The Rakhine region, where the Arakan Army has established dominance, holds immense strategic importance. It not only serves as a corridor for China’s Belt and Road Initiative but also impacts India’s connectivity projects like the Kaladan Multi-Modal Transit Transport Project. A weakened Myanmar military and a strengthened Arakan Army could give India greater access and influence in the region, countering Chinese designs.


If Ajit Doval’s fingerprints are indeed on this development, it could go down as one of his most effective manoeuvres — a masterstroke in securing India’s eastern frontier while subtly reshaping the geopolitical balance in South Asia.
