Environmental Pollutants as Emerging Concerns for Cardiac Diseases: A Review on Their Impacts on Cardiac Health

Biomedicines, Journal Year: 2025, Volume and Issue: 13(1), P. 241 - 241

Published: Jan. 20, 2025

Comorbidities related to cardiovascular disease (CVD) and environmental pollution have emerged as serious concerns. The exposome concept underscores the cumulative impact of factors, including climate change, air pollution, chemicals like PFAS, heavy metals, on health. Chronic exposure these pollutants contributes inflammation, oxidative stress, endothelial dysfunction, further exacerbating global burden CVDs. Specifically, carbon monoxide (CO), ozone, particulate matter (PM2.5), nitrogen dioxide (NO2), sulfur (SO2), pesticides, micro- nanoplastics been implicated in morbidity mortality through various mechanisms. PM2.5 leads inflammation metabolic disruptions. Ozone CO induce stress vascular dysfunction. NO2 cardiac remodeling acute events, metals exacerbate cellular damage. Pesticides microplastics pose emerging risks linked tissue Monitoring risk assessment play a crucial role identifying vulnerable populations assessing pollutant impacts, considering factors age, gender, socioeconomic status, lifestyle disorders. This review explores disease, discussing risk-assessment methods, intervention strategies, challenges clinicians face addressing pollutant-induced diseases. It calls for stronger regulatory policies, public health interventions, green urban planning.

Purpose of review This explores the complex relationship between climate change and cardiovascular health. It examines mechanisms through which impacts risk, highlights recent findings on regional trends, discusses mitigation strategies. Recent Climate significantly contributes to morbidity mortality such as temperature extremes, air pollution, food insecurity. Heatwaves increase risks dehydration, electrolyte imbalance, acute events, while cold spells exacerbate myocardial stress pollution-related risks. Air including fine particulate matter (PM2.5), induces systemic inflammation, endothelial dysfunction, atherosclerosis. Emerging data highlight variations, with urbanization exacerbating in Asia-Pacific Middle Eastern populations, extreme heat challenge resilience Europe Latin America.

The global burden and biomarkers of cardiovascular disease attributable to ambient particulate matter pollution

Journal of Translational Medicine, Journal Year: 2025, Volume and Issue: 23(1)

Published: March 22, 2025

Understanding the evolving patterns of cardiovascular disease (CVD) burden attributable to ambient particulate matter pollution (APMP) is essential. Furthermore, research on underlying mechanisms has mostly been limited laboratory and animal models, with few large-scale population-based studies. Using data from Global Burden Disease Study (GBD) 2021, we analyzed disability-adjusted life years mortality for CVD APMP (measured as [PM]2.5) 1990 2021. We examined shifts in between household air (HAP), regional disparities by socio-demographic index (SDI), predicted trends using a Bayesian age-period-cohort model. Additionally, used UK Biobank (UKB) (metabolomics: 230,000 + participants; proteomics: 50,000 +) identify biomarkers mediating association PM2.5 exposure outcomes, further their biological roles. Metabolic proteomic signatures were constructed regression elastic net predictive performance assessed via time-dependent receiver operating characteristic analysis. Life expectancy was evaluated flexible parametric survival models. Subgroup analysis conducted age, sex, lifestyle, socioeconomic status, genetic susceptibility. In global absolute more than double that 1990, significant disparities. The shifted HAP APMP, 15% cases globally attributed APMP. increased age projected rise through 2030.
