Italian cardiologists are implementing a One Health approach that connects cardiovascular prevention with environmental protection, highlighting Mediterranean diet benefits alongside emerging 'silent killer' risk factors including air pollution, noise pollution, light pollution, and chemical contamination of land and water. This represents a significant shift from traditional cardiovascular risk assessment that typically focuses on individual lifestyle factors like smoking, hypertension, and cholesterol levels. The environmental health connection acknowledges mounting evidence that pollution exposure contributes substantially to cardiovascular disease burden, particularly in urban populations. While the Mediterranean diet has well-established cardiovascular benefits through anti-inflammatory mechanisms and improved lipid profiles, framing it within environmental sustainability adds a compelling dual benefit narrative. However, this initiative appears more focused on awareness campaigns and screening programs rather than presenting novel research data. The One Health framework, while conceptually sound, requires more rigorous epidemiological evidence to quantify how environmental interventions translate into measurable cardiovascular outcomes. This represents an incremental evolution in prevention messaging rather than a paradigm shift, though the integration of environmental and cardiovascular health could influence future research priorities and public health policy.
