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.

High-Wire Act: Navigating the China Dilemma in Tough Times

Sri Lanka

Anura Kumara Dissanayake’s landslide (and unsurprising) electoral win to the presidency of Sri Lanka introduces a new chapter in the country’s long relationship with China. Known for his Marxist roots and pragmatic leadership, Dissanayake faces the formidable task of navigating this sometimes-schizophrenic relationship with Beijing while safeguarding Sri Lanka’s autonomy.


Sri Lanka’s relationship with China dates back centuries, with early ties marked by the maritime Silk Road. However, modern relations solidified during the Cold War era when Sri Lanka, then Ceylon, sought diplomatic connections that extended beyond Western powers. In 1952, Sri Lanka and China signed the Rubber-Rice Pact, a crucial trade agreement that secured economic ties at a time when Western trade embargoes on China were stringent.


This agreement not only defied Western trade embargoes on China but also laid the groundwork for a relationship that would deepen over subsequent decades.


During the Cold War, Ceylon adopted a non-aligned foreign policy, leveraging relationships with both Western and Eastern blocs. China, under Mao Zedong, saw strategic value in extending its influence into the Indian Ocean, and Sri Lanka was a willing partner, keen on balancing Western and Indian hegemony. These early interactions laid the foundation for a complex relationship characterized by both economic collaboration and strategic caution.


In the decades following the Cold War, China’s economic heft exponentially, and Sri Lanka’s strategic location made it an attractive partner. By the early 2000s, China’s Belt and Road Initiative (BRI) began to reshape this relationship, transforming it from one of balanced diplomacy to one marked by significant economic dependency. The Hambantota Port project, initiated in the late 2000s, exemplified this shift. Initially envisioned as a way to bolster the national economy, it became a cautionary tale when Sri Lanka was forced to lease the port to China on a 99-year agreement after struggling with debt repayment. This event sparked global debate on China’s “debt-trap diplomacy” and underscored the risks of disproportionate reliance on Beijing’s funding.


Incidentally, Dissanayake, who hails from the socialist Janatha Vimukthi Peramuna (JVP), was a vocal critic of such agreements long before he ascended to the presidency. His party, known for its anti-imperialist and anti-capitalist rhetoric, has historically maintained a wary stance toward powerful economic influencers, including China. While Dissanayake has criticized Beijing’s lending practices, he acknowledges the reality that China remains a crucial economic partner. His challenge lies in navigating these contradictory imperatives.


In October 2024, Dissanayake’s first official visit to China as president underscored his approach. During meetings with President Xi Jinping, he secured a key debt restructuring agreement that provided much-needed relief to Sri Lanka’s struggling economy. This move was a testament to Dissanayake’s strategic diplomacy—leveraging ties for immediate economic stability while aiming to maintain Sri Lanka’s sovereignty.


China’s involvement in Sri Lanka extends beyond economic projects; it encompasses strategic interests, including influence over the Indian Ocean’s vital trade routes. The Colombo Port City, another major Chinese-backed venture, represents both opportunity and risk. While it promises job creation and economic stimulus, it also exemplifies Beijing’s expanding footprint in the region, a development that has drawn scrutiny from India and Western nations. For China, having a significant presence in Sri Lanka bolsters its position in a broader geopolitical competition with India and the United States.


The Hambantota Port lease remains a symbol of the challenges Sri Lanka faces. Critics of the deal argue that it compromised national sovereignty and showcased China’s leverage over smaller, indebted nations. Dissanayake, with his deep-rooted political ideology and history of advocating for Sri Lankan independence, must tread carefully to avoid repeating past mistakes. His administration has pledged to review and, where possible, renegotiate terms of existing agreements to better align them with national interests.


For Dissanayake, balancing economic growth and autonomy is a high-wire act. He faces pressure from domestic critics wary of overdependence on China and international observers who question Sri Lanka’s ability to resist Beijing’s geopolitical sway. Dissanayake’s administration has made overtures to other global powers, including India and Western allies, to counterbalance China’s influence. Yet, the reality remains that Chinese investment continues to be a pillar of Sri Lanka’s economic landscape.


The historical trajectory of Sri Lanka’s relationship with China offers important lessons. The Rubber-Rice Pact demonstrated the potential for mutually beneficial agreements that respect sovereignty, but the Hambantota Port lease underscored the perils of over-leverage. The broader historical context also reveals a cycle of reliance and caution that has characterized Sri Lanka’s engagements with larger powers.


Today, Dissanayake’s government must chart a path that maximizes economic gains from China while diversifying partnerships to reduce dependency. One approach Dissanayake is likely to pursue involves increased economic engagement with India, Japan, and other regional stakeholders. By doing so, Sri Lanka could create a broader economic base that mitigates the risks associated with reliance on any single power. However, this strategy demands deft diplomacy to avoid alienating Beijing, which has shown a willingness to flex its economic muscle when challenged.


The stakes for Dissanayake are high. Success would mean steering Sri Lanka toward sustainable growth while maintaining independence in foreign policy—a model that could be instructive for other nations caught between major global powers. Failure, however, could entrench Sri Lanka further in economic vulnerability and geopolitical subordination.


Sri Lanka’s economic landscape has been shaped by a series of pivotal events involving China. From the initial enthusiasm of early trade agreements to the controversies surrounding major infrastructure projects, each era has left its mark on the national consciousness. Dissanayake’s tenure will be measured by his ability to navigate this legacy. His pragmatic approach must balance ideological commitment to national sovereignty with the practical needs of economic survival.


Beyond infrastructure, China’s influence extends into sectors like technology, energy, and tourism. Chinese investments in these areas have fueled growth, but they have also raised concerns about data security, resource control, and local job displacement. Dissanayake’s administration will need to establish clear policies that harness these investments for national benefit while safeguarding strategic interests.


Furthermore, the public’s perception of China has evolved. While earlier generations viewed Chinese partnerships as opportunities, recent years have fostered scepticism due to high-profile cases of debt distress and governance challenges. To win public confidence, Dissanayake must demonstrate transparency in dealings with China, ensuring that agreements are scrutinized for fairness and long-term benefit.


Dissanayake’s presidency is still in its early days, but his approach to China will serve as a litmus test for his broader policy of balancing economic pragmatism with national sovereignty. The world will be watching as Sri Lanka attempts to walk this diplomatic tightrope, where each step could mean the difference between prosperity and peril.
