Rising Cases of Sudden Cardiac Arrest


Team GSRN| New Delhi|14-04-2025
We are witnessing a global rise in cases of sudden cardiac arrest (SCA). It's important to understand that cardiac arrest and heart attack are not the same. Sudden cardiac arrest (SCA) is the sudden loss of all heart activity due to an irregular heart rhythm called ventricular fibrillation., leading to a sudden stop in heart function, breathing, and consciousness. Immediate treatment, such as CPR is given to help revive the patient during a cardiac emergency, whereas heart attack happens when blood flow to a part of the heart is blocked. However, a heart attack can cause a change in the heart's electrical activity that leads to sudden cardiac arrest.
In India, data from the Indian Heart Association (IHA) indicates that over 50% of heart attack deaths occur in people under 50, and 25% in those under 40. Sedentary lifestyles, poor dietary habits, smoking, and rising levels of hypertension and diabetes have compounded the crisis. A Lancet study also revealed that air pollution is an increasingly prominent cardiovascular risk factor in South Asia.
Since the COVID-19 pandemic, doctors around the world have noticed a rise in sudden heart-related deaths. Some research suggests that the virus can damage the heart and blood vessels, even after recovery. Many people who had mild or moderate COVID-19 are now showing signs of heart issues like inflammation, irregular heartbeat, and blood clots, sometimes months later. This has raised serious concerns among health experts, who believe the virus may have long-term effects on the cardiovascular system. As a result, doctors are urging people who had COVID-19 to go for regular heart check-ups, even if they feel fine.

Climate change reshapes global weather patterns: India's 2025 outlook

By Preety Chaudhary| 02 May, 2025 As the climate crisis intensifies, 2025 has emerged as a pivotal year, with India experiencing unprecedented weather extremes that underscore the urgent need for adaptive strategies. India faced an early and intense heatwave in April 2025, with temperatures soaring above 40°C in Delhi and reaching a staggering 46.4°C in Barmer, Rajasthan. Such extremes are becoming increasingly common, attributed largely to human-driven climate change. Meanwhile, the Himalayas recorded their lowest snowfall in 23 years, threatening the freshwater supply for nearly two billion people across Asia. This decline jeopardizes agriculture, hydropower, and drinking water resources in the region. Globally, abrupt temperature shifts rapid transitions between extreme heat and cold have increased, affecting over 60% of the planet. These fluctuations, driven by jet stream changes and soil moisture variations, pose significant challenges to agriculture and infrastructure. Climate ch...

Farmers and Pesticide Exposure in India: A Growing Concern

By Preety Chaudhary| May 4 ,2025 Delhi: Pesticide exposure remains a serious threat to the health and safety of Indian farmers. Recent studies have revealed alarming trends in both awareness levels and the adoption of preventive measures across agricultural communities. A study in Telangana highlighted that farmers are facing a range of health issues, including respiratory problems, skin disorders, and even neurological symptoms, due to unsafe pesticide practices. Many still handle chemicals without adequate protective gear or proper knowledge of safety protocols. In North India, over 55% of farmers reportedly do not read pesticide labels, while nearly 80% remain unaware of bans or restrictions on certain chemicals. The widespread ignorance about personal protective equipment (PPE) further increases their vulnerability. Despite the risks, conventional pesticides continue to dominate Indian agriculture due to their high efficacy, affordability, and long-lasting action. These chemicals a...
