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.

Dangerous Trend

Updated: Oct 22, 2024

In a troubling display of misplaced priorities, several political leaders and parties in poll-bound Jammu & Kashmir, including Mehbooba Mufti’s Peoples Democratic Party (PDP) and the National Conference (NC), have recently shown ‘solidarity’ following the death of Hassan Nasrallah, the militant Hezbollah leader killed in an Israeli airstrike in Beirut. This episode raises a fundamental question: why do sections of India’s political and intellectual elite, who proclaim allegiance to liberal values, often end up pandering to militant causes and championing individuals with a violent, anti-Indian agenda?

Nasrallah, a symbol of Middle Eastern extremism and global terrorism, was responsible for years of violence grounded in hate for Israel and the West. One would expect Indian politicians, especially those claiming to represent the aspirations of Jammu & Kashmir’s beleaguered population, to maintain a prudent distance from such figures.

This is not an isolated instance. For years, prominent members of India’s so-called ‘liberal’ intelligentsia have extended their support to individuals like Yasin Malik, a separatist leader with blood on his hands. Malik’s long record of violence, including involvement in the killings of Indian Air Force personnel, did little to tarnish his image among certain political circles. Even as he was being tried for terrorism, sections of the media and academia feted him as a ‘freedom fighter,’ turning a blind eye to the victims of his crimes.

The double standard is stark when compared to democracies like Israel, where all major parties agree that terrorism is never justified regardless of fierce ideological divisions. This consensus has enabled Israel to decisively deal with its security challenges, even when doing so requires difficult decisions.

Political opportunism still plagues Jammu & Kashmir, where leaders often pander to populist sentiment instead of upholding peace and pluralism. The recent display of solidarity with Nasrallah exemplifies this duplicitous strategy—a cynical bid to appease hardline factions that sympathize with militancy.

It is not just the political class in Kashmir that is at fault. Intellectuals in metropolitan India, many of whom are quick to condemn military excesses or human rights violations by the state, are often conspicuously silent when it comes to acts of terror committed by separatists. They couch their arguments in the language of ‘resistance’ and ‘liberation,’ overlooking the fact that militant leaders like Yasin Malik or Burhan Wani seek not justice but the disintegration of India. India’s leaders must take a page from Israel’s playbook. Terrorism is not an issue that can be tackled with half-measures or soft rhetoric. It requires a resolute stance, not only from the state but also from society at large. Political parties that support or sympathize with terrorists, either overtly or through implicit endorsement, must be called out and held accountable.
