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.

Pakistan’s missile programme: Strain ties with US, China

Pakistan’s missile programme: Strain ties with US, China

The recent imposition of US sanctions targeting Pakistan’s ballistic missile program has left authorities in Islamabad both shocked and deeply concerned. On Thursday, the US State Department imposed restrictions on several Chinese companies and a research institute accused of supplying critical technology to Pakistan’s missile capabilities.

The sanctions focus on China’s alleged role in supporting Pakistan’s missile programme, with the US accusing the Beijing Research Institute of Automation for Machine-Building Industry of assisting Islamabad in procuring equipment used to test rocket motors for the Shaheen-3 and Ababeel missile systems. These systems form the backbone of Pakistan’s missile arsenal, which is seen as crucial for maintaining a strategic balance in the region, particularly with India.

In addition to the Beijing Research Institute, the US also sanctioned Chinese companies Hubei Huachangda Intelligent Equipment Co., Universal Enterprise, and Xi’an Longde Technology Development Co. A Pakistan-based firm, Innovative Equipment, and a Chinese national were similarly targeted for knowingly transferring equipment restricted under missile technology regulations. According to US State Department spokesperson Matthew Miller, these actions reflect Washington’s commitment to countering missile proliferation and associated procurement activities wherever they occur.

This latest move follows an earlier round of sanctions in October 2023, when three China-based companies were similarly targeted for supplying missile-related items to Pakistan. The cumulative effect of these sanctions has triggered widespread concern within Islamabad. Although Pakistani authorities have not made any formal public statement, sources suggest these sanctions are viewed as a significant blow, especially when Pakistan grapples with severe economic challenges.

China, Pakistan’s long-time ally, has reacted strongly to the sanctions. Liu Pengyu, the spokesperson for the Chinese embassy in Washington, condemned the sanctions as a breach of international law, criticising the US for its “unilateral actions and long-arm jurisdiction.” Liu further stated that China would “firmly protect” the rights and interests of its companies and citizens, signalling that Beijing does not intend to take these measures lightly.

The imposition of these sanctions has reignited debate about US-Pakistan relations. For many in Pakistan, this latest move reaffirms long-standing suspicions about the United States’ reliability as an ally. Despite Pakistan’s significant sacrifices in the US-led war on terror—both in terms of human lives and economic losses—Washington’s actions continue to strain bilateral ties. The view that the US has never been a true friend of Pakistan is gaining traction, particularly among those who feel that Islamabad’s contributions to global counterterrorism efforts have been overlooked.

This growing sentiment has increased scrutiny of Pakistan’s foreign policy approach towards the United States. Analysts and foreign policy experts are asking whether Islamabad’s historical reliance on Washington remains a viable strategy in today’s geopolitical climate. Some suggest the time has come for Pakistan to reconsider its approach and explore a broader range of alliances.

Among the most prominent suggestions is to adopt a foreign policy model similar to India’s. Despite the complex global landscape, India has managed to maintain strong relationships with the United States, Russia, and China simultaneously, allowing it to navigate competing global interests while protecting its national priorities. In contrast, Pakistan’s foreign policy has often been viewed as too dependent on its ties with Washington, leaving it vulnerable to actions such as these latest sanctions.

Conversations with senior government officials reveal mounting pressure within Islamabad’s foreign policy establishment to reassess the country’s strategy. Many argue that if India can successfully balance its relationships with multiple global powers, Pakistan should be capable of pursuing a similar approach. A shift in this direction could help Islamabad mitigate the risks associated with over-reliance on a single ally and open up new diplomatic and economic opportunities.

The current trajectory of US-Pakistan relations appears increasingly uncertain, and the imposition of these sanctions has underscored the need for a strategic recalibration. While Washington continues to wield significant influence on the global stage, Pakistan may find it prudent to cultivate stronger ties with other major powers, such as China and Russia, to create a more balanced and diversified foreign policy.

Such a shift, however, would not be without its challenges. The United States remains a key global player, and its influence over international institutions and financial systems cannot be ignored. Nevertheless, for Pakistan, the risk of continuing to rely on a single, often unpredictable partner may outweigh the potential benefits.

As the debate over Pakistan’s foreign policy direction intensifies, it is clear that the US sanctions have not only impacted the country’s missile programme but have also triggered a broader reassessment of its strategic alliances. For Islamabad, the future likely lies in forging a path that reduces dependency on any one power while simultaneously enhancing its relationships with multiple global actors. This approach could offer greater resilience in an increasingly multipolar world, where flexibility and balance are key to safeguarding national interests.
