Cardiologists raise red flag: Bengaluru’s pollution fuelling heart attacks

In a concerning revelation, cardiologists from the Cardiological Society of India have raised alarm over the rising number of heart attacks in Karnataka, pointing towards increasing levels of air and noise pollution as contributing factors. A recent study, themed ‘Heart Attack & Air Pollution’, draws a direct link between deteriorating air quality and cardiovascular emergencies.

Data from Bengaluru shows a noticeable spike in pollution levels across several areas. In HSR Layout, the Air Quality Index (AQI) reached 191 on May 16 and further climbed to 192 by May 22. These levels, while not classified as hazardous, indicate persistent exposure to poor air quality that could significantly impact public health, especially among vulnerable groups like senior citizens and those with pre-existing heart conditions.

Experts argue that Bengaluru is not alone in this trend. Several parts of Karnataka are witnessing similar patterns of pollution rise, prompting wider concern. While vehicle emissions remain the primary culprit, multiple other factors are aggravating the situation. Broken and poorly maintained roads have led to slow-moving traffic, which increases both air and noise pollution due to constant honking and vehicle idling.

The city, which houses over 1.5 crore vehicles, is struggling with outdated, smoke-emitting vehicles that continue to pollute the air. Roadside dust, construction debris, and lack of efficient traffic regulation are compounding the issue. These conditions not only deteriorate air quality but also elevate the risk of cardiovascular complications.

Data from the Karnataka State Pollution Control Board confirms this worrying trend. In May, AQI levels in Kengeri and HSR Layout consistently remained high. For instance, May 6 recorded an AQI of 144, May 7 at 130, May 16 at 191, May 22 at 192, and May 31 at 157, figures that represent a steady decline in air quality over the month.

As noise pollution from traffic becomes a chronic problem, residents are left with no reprieve. Cardiologists stress the urgent need for systemic interventions, including better traffic flow, road repairs, stricter emission checks, and public awareness campaigns to reduce the looming risk of pollution-induced heart diseases.
