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.

Army chief reviews J&K security after Pahalgam terror attack that killed 26


ree

NEW DELHI: Army Chief General Upendra Dwivedi on Friday reviewed the security situation and ongoing ground operations in Jammu and Kashmir following the Pahalgam terror attack that killed 26 people, most of them tourists.


General Dwivedi joined senior Army commanders for a security review meeting chaired by Lieutenant Governor Manoj Sinha. According to sources, the L-G said those behind the Pahalgam attack must be hunted down and made to pay a heavy price for the brutal act.


Sinha directed the Army Chief to ensure not only that the attackers are brought to justice, but also that operations to dismantle the terror infrastructure and its support system are intensified.


He added that the nation has complete trust in the bravery of the Army, police, and Central Armed Police Forces (CAPFs), and urged them to work together closely to identify and eliminate the perpetrators, enablers, and overground workers (OGWs) involved in the attack.


“Every person behind or supporting the Pahalgam terror attack, no matter where they are or who they are linked to, must be found and held accountable for this cowardly and brutal crime against our people,” Sinha told the Army leadership.


After arriving in Srinagar, General Dwivedi visited Awantipora, the base of the Counter Insurgency Force—Victor, where he was briefed on operations following the attack, a source said. He then moved to the 15 Corps headquarters at Badami Bagh Cantonment and met Lt Gen Prashant Srivastava, the Corps Commander.


The Army Chief was updated on the actions being taken to stop terrorist activity and respond to ceasefire violations by the Pakistan Army along the Line of Control (LoC). Top officers, including the Director General of J&K Police and other senior officials, discussed the current situation and future plans.


General Dwivedi also briefed L-G Sinha at Raj Bhawan, along with Lt Gen MV Suchindra Kumar, GOC-in-C Northern Command, Deputy Army Chief Lt Gen Pratik Sharma, and Lt Gen Srivastava.


On the night before the Army Chief’s visit, there was heavy firing along the LoC. “Around 600 rounds were fired from the Pakistan side at Tutmari Gali in Kupwara. In response, the Indian Army fired about 1300 rounds,” an officer said. “Pakistan troops fired from multiple points along the LoC,” he added.
