Answer

Introduction

Rapid urbanisation reshapes living patterns through air quality, diets, stress, and mobility, quietly amplifying non-communicable risks. India’s urban pockets now face rising cardiovascular vulnerabilities intertwined with pollution, inequity, and sedentary routines, demanding integrated, heart-conscious city design beyond siloed public health fixes.

Key challenges driving cardiovascular risks

• Air pollution: Persistent PM2.5 exposure drives inflammation, hypertension, and atherosclerosis, elevating urban CVD risk across seasons and neighborhoods. 
• Diet transitions: Processed, salty foods in cities fuel hypertension and metabolic strain, worsening heart outcomes across socioeconomic groups.
  Eg: ICMR finds urban salt intake at 9.2g/day—nearly double WHO’s safe limit (<5gm/day).
• Sedentary lifestyles: Car-centric design, long commutes, and screen time reduce daily activity, raising obesity, diabetes, and hypertension risks. 
• Chronic stress: High-pressure work cultures, gig-economy precarity, and social isolation contribute to stress-driven cardiac events.
  Eg: “Urban heart syndrome” linked to lifestyle stressors.
• Health inequities: Informal workers lack accessible primary care, delaying prevention and early cardiac intervention in dense urban pockets. 
• Heat islands: Rising urban temperatures intensify dehydration, tachycardia, and strain on vulnerable hearts, compounding pollution effects. 

Policy measures for heart‑resilient urban planning

• Clean air action: Tighten NCAP targets, PM2.5 monitoring, and industrial-combustion controls; integrate health co-benefits in planning. 
• Active mobility: Build shaded footpaths, cycling grids, and last-mile transit; incentivise 15-minute city designs to embed daily activity.
  Eg: “Heart-friendly” urban planning prioritising walkability.
• Green buffers: Expand parks, urban forests, and cool roofs to cut heat islands, stress, and blood pressure through restorative spaces. 
• Salt reduction: Mandate front-of-pack warnings, reformulate foods, and run urban salt-awareness campaigns through community kitchens.
  Eg: ICMR initiates community-led salt reduction pilots.
• Workplace wellness: Enforce ergonomics, movement breaks, and stress-screening in corporate and gig platforms; integrate cardiac risk checks. 
• Urban primary care: Strengthen HWC networks, screening camps, and referral chains in slums; deploy mobile clinics for the informal sectors. 

Conclusion

Heart-resilient cities hinge on integrating air quality, mobility, green infrastructure, food environments, and equitable primary care—so urban growth enhances cardiovascular resilience rather than silently eroding it through stress, pollution, and exclusion.
