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.

Putin’s Nuclear Gambit in a New Age of Brinkmanship

Updated: Oct 21, 2024

utin’s Nuclear Gambit in a New Age of Brinkmanship

In American filmmaker Sidney Lumet’s 1964 classic ‘Fail-Safe,’ a technical malfunction sends American bombers hurtling towards Moscow, triggering a countdown to nuclear war. As the clock ticks down, both the United States and the Soviet Union are trapped in a desperate struggle to avoid mutual annihilation. The film captures the chilling fear of miscalculation and the terrifying consequences of nuclear brinkmanship - a reality that seems far from fiction once more. This week, Russian President Vladimir Putin issued a stark warning to the West: if Russia were struck with conventional missiles by Ukraine, it could respond with nuclear weapons.

Furthermore, Moscow would consider any assault on it, backed by a nuclear power, as a joint attack - a signal that the risk of escalation has returned to center stage in global affairs. Putin’s warning followed after Ukrainian President Volodymyr Zelensky’s recent impassioned appeal for military support at the United Nations, following which the Russian President unveiled a ‘draft’ nuclear doctrine. Putin and his aides have been indicating a potential shift in Russia’s nuclear doctrine for some time now, the doctrine being the document which governs the deployment of its extensive nuclear arsenal - said to be the largest in the world.

Since the onset of Russia’s full-scale invasion of Ukraine in February 2022, Putin and his inner circle have consistently invoked the specter of nuclear deterrence.

The Kremlin has urged the West to take Vladimir Putin’s latest nuclear threat seriously. In response, U.S. President Joe Biden, while confirming the provision of additional long-range munitions to Ukraine - including the Joint Standoff Weapon (JSOW) – but reiterated the restrictions on using these weapons against Russian targets. During a meeting with Ukrainian President Volodymyr Zelenskyy at the White House, Biden reiterated the U.S. commitment to supporting Ukraine against Russian aggression.

The question is if Putin’s latest gambit is a calculated bluff, like so many of the threats during the Cold War. History offers stark reminders of how easily these games of chicken can spiral out of control. The Cuban Missile Crisis remains the archetypal example of a nuclear standoff. In October 1962, the United States discovered Soviet missiles in Cuba, sparking a tense 13-day confrontation during which the world came terrifyingly close to a nuclear apocalypse.

During the standoff, a Soviet submarine, surrounded by American ships, had nearly launched a nuclear torpedo, only to be stopped by a last-minute intervention from one of its officers

In his definitive account of the Cuban Missile Crisis ‘Abyss’, distinguished historian Max Hastings sharply criticizes Nikita Khrushchev’s decision to send nuclear missiles to Cuba, despite the Soviet leader’s memoirs justifying it as a response to U.S. missiles near Soviet borders. Initially, most American leaders, including US President John F. Kennedy, had backed military strikes, risking nuclear war. However, Hastings credits Kennedy’s restraint -choosing a naval blockade and warning Khrushchev, who withdrew the missiles - as an act of rare statesmanship. He argues that many successors would have chosen war, making Kennedy’s decision pivotal in averting disaster.

But this would not be the last time the world faced such peril. In 1983, NATO’s military exercise ‘Able Archer’ nearly triggered a Soviet pre-emptive nuclear strike.

The war games simulated the escalation of conflict into nuclear warfare, but the Soviet Union, interpreting the drill as a cover for an actual attack, put its forces on high alert. It was the intervention of Oleg Gordievsky, a KGB defector working with British intelligence, that alerted the West to Soviet paranoia, thus preventing a possible Armageddon.

In another instance of the perilous fallout of Cold War brinkmanship, in March 1986, the Soviet nuclear submarine K-219 sank in the Atlantic following a missile tube explosion, raising fears of sensitive nuclear material falling into enemy hands. The U.S. Navy deployed ships to monitor the situation, heightening tensions as both sides grappled with the incident’s implications. While direct confrontation was avoided, the incident starkly underscored the risk of accidental escalation.

Putin’s rhetoric, like Khrushchev’s during the Cuban Missile Crisis, may well be aimed at rattling Western nerves. But the stakes are different now.

The prospect of nuclear escalation is also compounded by the erosion of communication channels between Moscow and the West, given the steady deterioration of relations since the past decade. During the Cold War, hotlines between Washington and Moscow had often played a critical role in defusing crises.

Today, however, the collapse of arms control agreements and the deterioration of diplomatic relations have left the West and Russia without many of the safeguards that once existed. The New START treaty, the last remaining nuclear arms control pact between the U.S. and Russia, is now on shaky ground. Without these structures in place, the risk of miscalculation rises significantly.

Putin’s current posturing bears uncomfortable similarities to these Cold War episodes. His nuclear posturing, like the fictional bombers of ‘Fail-Safe,’ puts the world on a terrifying countdown. Whether the West can steer clear of the same disastrous miscalculations that nearly brought the world to the brink in 1962 and 1983 will depend on cool heads and a renewed commitment to diplomacy in both the US and the European Union. As history has shown time and again, the line between threat and catastrophe is perilously thin.
