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.

Lost on Everest: A Century of Unsolved Mystery

Lost on Everest: A Century of Unsolved Mystery

More than a century ago, a man was asked a question at a lecture he was giving in the United States. The answer to that question defined the closing stages of the golden age of adventure and exploration. The question was ‘Why climb Everest?’. The answer was ‘Because it’s there’. The man who gave this answer defined future generations of mountaineers and gave birth to one of most enduring mysteries of the 20th Century - one which still endures in the 21st, and more importantly remains unsolved.

Lost on Everest: A Century of Unsolved Mystery

The man was George Leigh Mallory, who, along with his young climbing partner Andrew ‘Sandy’ Irvine attempted in 1924 to summit Mount Everest from the treacherous North Face on the Tibetan side. They were seen for the last time on June 8, 1924, a few hundred feet short of the summit. According to Noell Odell, the man who saw them, they were going strong. Then the clouds rolled in and Mallory and Irvine were never seen again.


In 1999, an expedition was launched to try to find the bodies of Mallory and Irvine and the camera carried by Irvine, which carried a roll of Kodak film. Kodak believed the film, preserved by the extreme cold, could still be developed, potentially solving the mystery of whether they reached Everest's summit 29 years before Hillary and Norgay's successful ascent in 1953.


American mountaineer Conrad Anker, part of the team, made an astounding discovery - the body of Mallory sprawled on the


. Although Mallory’s remains were remarkably well preserved, the expedition failed to find the clue that could solve the mystery - the camera. However, other clues suggested Mallory and Irvine were able to summit Everest.


Mallory’s snow goggles were in his pocket, which suggested he (and possibly Irvine) were on their descent. But here, a significant clue was missing - a photograph of Mallory’s wife Ruth. He had promised Ruth if he made it to the summit, he would place her photograph there.


Last month, exactly 100 years on, another expedition came across a foot on the slopes of the North Face. A closer examination of that revealed a name tag - A. Irvine. It was Sandy Irvine’s foot.


The tale of Mallory and Irvine’s 1924 expedition to Everest has continued to fascinate and flummox mountaineers and historians. Mallory was perhaps the best climber of his generation. The 1924 expedition was his third Everest foray. Mallory first visited Everest in 1921, where he discovered a potential route to the summit. In 1922, he and his team reached 27,000 feet - the highest altitude achieved at that time - but a monsoon thwarted their ascent. The expedition ended tragically when an avalanche struck during their descent from the North Col, claiming the lives of seven climbers - the first fatalities on the mountain.


In 1924, Mallory was 37, and he knew that this would be his final chance to conquer Everest. He chose the inexperienced 22-year-old Irvine as his climbing partner. Mallory knew that supplemental oxygen would be key for a successful summit. Irvine was just the man for the job as he knew how to work the rather primitive oxygen apparatus. After going through the motions of establishing camps along the way the pair finally reached the camp from which they would make the final assault. In their path lay the second step - a hundred-foot cliff which they would have to free climb. The second step was the crux of the climb. Today climbers scale it with the help of a ladder. But Mallory and Irvine had to do it in a free climb at 28,000 feet with 7,000 feet drop to the bottom of the mountain. And there lies the heart of the myth (or mystery) - did they do it or not?


But what is it that drove that generation to take these incredible risks? Why do it in face of such overwhelming odds? Why be away from one’s family and home for months and months? The answer perhaps lies in the gruesome experience that the First World War, of ‘The Great War’ of 1914-18 had offered such men. An entire generation had been wiped out in the trenches of Europe and the far-flung corners of the British Empire. For the survivors, it was perhaps a sense to make the most of what life had to offer. Mallory had served in the trenches of the Western Front and saw the carnage of the Somme. The quest for Everest offered a final frontier, a higher purpose. Wade Davis, in his monumental book ‘Into the Silence,’ suggests this pursuit of transcendence was what propelled Mallory and others from his generation.


Mallory and Irvin1e till this day lie on the North Face. But the mystery still demands a final answer.
