Heart disease is the leading cause of death across Europe, responsible for roughly 45 percent of all deaths each year. Yet the burden is distributed with striking unevenness. In virtually every major European city, cardiovascular mortality rates vary dramatically from one neighbourhood to the next — often by a factor of two or three within distances of only a few kilometres.
This is not purely a matter of individual choices. A growing body of evidence shows that where a person lives shapes their cardiovascular risk through mechanisms that operate independently of behaviour, genetics, or even access to medical care. The neighbourhood itself is a risk factor.
What Researchers Mean by the Neighbourhood Effect
The “neighbourhood effect” in cardiovascular health refers to the measurable impact of residential environment on health outcomes, over and above individual characteristics. Studies consistently find that people in deprived urban areas face significantly higher rates of cardiovascular disease even after controlling for smoking, diet, exercise, income, and other personal risk factors.
A 2019 analysis published in the European Heart Journal examined cardiovascular outcomes across multiple European urban populations and found neighbourhood deprivation independently associated with a 20 to 40 percent increased risk of major cardiovascular events. This held true even among individuals in the same income bracket — the neighbourhood they lived in added risk beyond what their own socioeconomic position alone would predict.
The Built Environment and Cardiovascular Risk
The physical characteristics of a neighbourhood shape heart health in direct ways. Streets without pavements or safe crossings discourage walking. Parks that are poorly maintained or perceived as unsafe reduce physical activity. Urban areas designed around cars rather than pedestrians systematically reduce the incidental daily movement that protects cardiovascular health.
In Madrid, research conducted as part of the HHH Project documented stark differences in the built environment between central and peripheral districts. Southern neighbourhoods like Villaverde and Vallecas had significantly fewer recreational green spaces per capita than wealthier northern districts, and residents reported higher perceived barriers to outdoor physical activity.
Food Environments and Chronic Stress
What researchers call the “food environment” — the density, type, and accessibility of food retail in a given area — differs markedly between affluent and deprived neighbourhoods. Fast food outlets and convenience stores cluster in lower-income areas, while supermarkets with affordable fresh produce are sparser. This pattern, documented in cities from London to Madrid to Edinburgh, shapes dietary patterns in ways that drive cardiovascular risk.
Equally important is chronic stress. Living in a neighbourhood with high crime rates, poor housing quality, noise pollution, and job insecurity imposes a persistent physiological burden. The body’s stress response systems remain activated at low but continuous levels. Over years, this wears down the cardiovascular system — raising blood pressure, promoting inflammation, and accelerating arterial damage.
Access to Healthcare
Proximity to healthcare matters, but it is not simply about distance. Research in the UK and Spain has consistently shown that people in deprived areas are less likely to receive appropriate cardiovascular medications, less likely to attend cardiac rehabilitation after a heart attack, and more likely to present to emergency departments rather than through preventive primary care pathways. The factors driving this include trust in healthcare systems, practical barriers like work schedules and transport, and the cumulative effects of navigating socioeconomic adversity.
The Policy Implication
Understanding cardiovascular disease as a neighbourhood-level phenomenon, not just an individual one, has significant implications for how prevention should be designed. Interventions that focus exclusively on changing individual behaviour — smoking cessation programmes, dietary counselling — have real value but cannot address the structural factors that place some populations at systematically higher risk.
Effective cardiovascular prevention requires attention to the upstream determinants: housing quality, neighbourhood safety, green space equity, the geography of tobacco retail density and alcohol outlets, and the economic conditions that generate chronic stress — a dynamic examined in depth when looking at the social determinants of cardiovascular disease. The evidence from European cities is unambiguous. The postcode a person is born into remains one of the strongest predictors of whether cardiovascular disease will cut their life short.
