Abstract
Cardiovascular diseases (CVD) are the leading cause of global non-communicable disease-related deaths. In recent years there has been increasing discussion about the influence of environmental risk factors, including noise and light, on the occurrence and course of these conditions. Recent studies highlight the impact of road traffic noise on an elevated risk of stroke and increased mortality in the course of coronary artery disease (CAD). In the case of threats arising from light pollution, there are more limited published studies; however, these show an increased hospitalization risk associated with CAD. Existing analyses cannot dismiss these environmental factors, highlighting the need for further research. Future studies should investigate not only road traffic noise but also consider railway and aircraft noise. Additionally, research on light pollution should include younger individuals too. In the future, incorporating individual assessments of noise and light pollution exposure, along with the identification of particularly vulnerable groups, could contribute to refining methods of individual risk stratification and implementing new preventive strategies.
