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.

Gun Violence in America

Updated: Jan 2

Gun Violence in America

On December 16, 2024, tragedy struck Abundant Life Christian School in Madison, Wisconsin, where a 15-year-old student, Natalie Rupnow, fatally shot a fellow student and a teacher before taking her own life. Six others were injured, with two in critical condition. This devastating event is a grim reminder of the United States' ongoing struggle with gun violence, particularly in schools.


A Long History of Gun Ownership in America

The issue of gun violence in the United States cannot be discussed without acknowledging its deep-rooted history of gun ownership. The right to bear arms is enshrined in the Second Amendment of the U.S. Constitution, adopted in 1791, which states: “A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.”


Initially, this amendment was intended to empower citizens to form militias for self-defense during a time when standing armies were distrusted. Over the centuries, however, the interpretation of the Second Amendment has evolved. Today, it is often cited as a justification for individual gun ownership, a concept reinforced by landmark court cases such as District of Columbia v. Heller (2008), which affirmed an individual's right to own firearms for self-defense.


Gun culture is deeply ingrained in American society, with nearly 400 million firearms in civilian hands—more guns than people. This level of accessibility, coupled with a powerful gun lobby led by organizations like the National Rifle Association (NRA), has made significant legislative reform difficult.


Gun Violence in Numbers

According to the Centers for Disease Control and Prevention (CDC), firearms cause approximately 40,000 deaths annually in the United States—equivalent to 109 deaths per day. This figure includes homicides, suicides, and accidental shootings. Among children and teenagers, firearms are now the leading cause of death, surpassing motor vehicle accidents.


School shootings are a particularly horrifying aspect of gun violence in America. Since 1990, there have been over 800 incidents in K-12 schools, resulting in more than 500 deaths and over 1,000 injuries. High-profile tragedies such as the Columbine High School massacre (1999), the Sandy Hook Elementary School shooting (2012), and the Marjory Stoneman Douglas High School attack (2018) have shocked the nation and the world, yet meaningful reforms remain elusive.


A Global Comparison

The United States stands out among developed nations for its high rate of gun violence. In countries like Australia, Canada, and much of Europe, strict gun control measures have significantly reduced firearm-related deaths. For example: By contrast, the firearm-related death rate in the United States is 12.2 per 100,000 people, significantly higher than other developed nations. The prevalence of guns and the lack of uniform gun control laws contribute to this disparity.


Challenges in Addressing Gun Violence

Efforts to reduce gun violence in the U.S. have faced significant obstacles. One of the most notable is the prohibition of federal funding for gun violence research. In 1996, Congress passed the Dickey Amendment, effectively barring the CDC from studying gun violence as a public health issue. Although the funding ban was partially lifted in 2019, its legacy has left the country with a limited understanding of the causes and solutions to gun violence.


Advocates have long called for measures such as:

• Universal Background Checks: Closing loopholes in gun sales to ensure that all firearm purchases are subject to background checks.

• Safe Storage Laws: Requiring gun owners to store firearms securely to prevent unauthorized access.

• Bans on Certain Firearms: Prohibiting the sale of assault-style weapons, which are often used in mass shootings.


The Debate Over Gun Rights and Reform

The debate over gun control in the United States often pits the rights of gun owners against the need for public safety. Opponents of stricter gun laws argue that restrictions infringe on constitutional rights and fail to address the root causes of violence, such as mental health issues. Proponents, however, point to the success of gun control measures in other countries and the overwhelming public support for policies like background checks.


A Way Forward

Despite the challenges, there is growing momentum for change. Grassroots organizations, survivors of gun violence, and some lawmakers are advocating for comprehensive reforms. The Madison school shooting serves as a stark reminder of the urgency of these efforts. As the nation grapples with its gun violence epidemic, it must look to both its history and the experiences of other countries to find a path toward a safer future.
