Cold wave triggers spike in cardiac arrests

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.

Dissanayake’s Win: A Shift Towards Leftist Politics

Updated: Oct 22, 2024

Dissanayake’s Win

Anura Kumara Dissanayake, the left-leaning candidate from the National People’s Power (NPP), decisively won against his primary opposition. The new president, a former trade union leader with an anti-elite stance, campaigned on promises of economic equality, greater state control over resources, and curbing foreign debt dependency. His socialist ideology emphasised nationalising key industries, fostering social welfare programmes, and limiting foreign influence—particularly that of Western nations.

The main contenders in this election included Ranil Wickremesinghe, the incumbent president from the United National Party (UNP), and Sajith Premadasa, the leader of the centre-right Samagi Jana Balawegaya (SJB). Despite fierce competition, Dissanayake’s promise of economic reform and critique of the 2022 economic crisis resonated with the electorate, who are still reeling from the economic shocks. Voter concerns centred on the unresolved debt crisis, unemployment, inflation, and the high cost of living, which dominated the election discourse.

Sri Lanka’s presidential elections have historically been a battleground for competing ideologies and foreign interests. Since gaining independence in 1948, the country has oscillated between socialist-leaning policies and pro-market, right-wing governance. Presidents like Chandrika Kumaratunga and Mahinda Rajapaksa advocated for greater state control, while more recent leaders, including Ranil Wickremesinghe, sought to liberalise the economy. Behind these political shifts is a geopolitical landscape where India and China vie for influence.


Influence of India and China

India has always been a key player in Sri Lanka, due to its geographical proximity and shared cultural heritage. However, China’s involvement has grown in recent years, driven by its Belt and Road Initiative (BRI). Sri Lanka’s strategically located ports, especially Hambantota, have made this island nation a focal point of China’s maritime ambitions. This dynamic has created a delicate balancing act for previous Sri Lankan presidents, requiring them to navigate the competing interests of these two Asian giants.

Economic Crisis and Survival

The so-called Chinese “debt trap” became a major issue during Mahinda Rajapaksa’s presidency. The country borrowed heavily from China to finance infrastructure projects, including the infamous Hambantota Port. These loans, with high interest rates, quickly became unsustainable.

By 2022, Sri Lanka faced an economic meltdown triggered by a foreign exchange crisis and exacerbated by the global pandemic. The country defaulted on its foreign debt for the first time in its history, leading to severe shortages of essential goods, widespread protests, and the resignation of President Gotabaya Rajapaksa.

Sri Lanka managed to recover through a combination of International Monetary Fund (IMF) assistance, temporary relief from creditors, and austerity measures. Yet, the scars of that crisis remain, and the recent election has highlighted lingering discontent among the population, especially over the perception that foreign influence was a key contributor to the economic collapse.


Impact on Indo-Lankan Relations

The election of Anura Kumara Dissanayake could significantly alter Indo-Lankan relations. India, which had strengthened ties with the previous government through economic support and strategic collaborations, may now face renewed competition from China. With Dissanayake’s commitment to reducing reliance on Western and multilateral institutions like the IMF, there are growing concerns that he may lean heavily on China for future financial and infrastructure support. This shift could reintroduce the risks of economic entanglement and sovereignty loss that Sri Lanka faced under the previous Rajapaksa administration.

From India’s perspective, the recent election has created new diplomatic challenges, coinciding with increasing hostility from most other neighbouring countries like Pakistan, China, Nepal, Bangladesh, and the Maldives. Once seen as a potential ally, Sri Lanka may now tilt towards Chinese influence, leaving India diplomatically isolated in the region, with Bhutan remaining its only ally. Given the current situation, it is crucial for the Government of India to focus more on its neighbours. An India surrounded by hostile neighbours will always be at risk, and these risks will escalate as India becomes stronger economically and militarily.


Cautious Optimism for the Future

While it’s too early to make definitive judgements on the trajectory of Sri Lanka’s foreign and domestic policies under the new president, signs indicate Sri Lanka may be heading towards another phase of Chinese influence. However, given the disastrous consequences of previous involvement in China’s debt trap, the new government should tread carefully.

India, for its part, must remain watchful and proactive and continue to focus on diplomatic engagement, economic assistance, and strengthening cultural ties with Sri Lanka to counterbalance China’s financial allure. At the same time, India must recognise the changing political winds and prepare for a future where its neighbours may not always be aligned with its strategic goals. The outcome of this election serves as a reminder that regional stability is fragile, and India’s role in South Asia has never been more crucial.

As Sri Lanka embarks on this new political chapter, the world is watching it closely and cautiously.
