Air Pollution's Impact On Our Circulatory System

Air pollution is a complex mixture of gaseous and particulate components, each of which has detrimental effects on human health. While the composition of air pollution varies greatly depending on the source, studies from across the world have consistently shown that air pollution is an important modifiable risk factor for significantly increased morbidity and mortality. Moreover, clinical studies have generally shown a greater impact of particulate matter (PM) air pollution on health than the gaseous components. PM has wide-ranging deleterious effects on human health, particularly on the cardiovascular system. Both acute and chronic exposure to PM air pollution is associated with increased risk of death from cardiovascular diseases including ischemic heart disease, heart failure, and ischemic/thrombotic stroke. Particulate matter has also been shown to be an important endocrine disrupter, contributing to the development of metabolic diseases such as obesity and diabetes mellitus, which themselves are risk factors for cardiovascular disease. While the epidemiological evidence for the deleterious effects of PM air pollution on health is increasingly accepted, newer studies are shedding light on the mechanisms by which PM exerts its toxic effects. A greater understanding of how PM exerts toxic effects on human health is required in order to prevent and minimize the deleterious health effects of this ubiquitous environmental hazard. Air pollution is a growing public health problem and mortality due to air pollution is expected to double by 2050.

Air pollution is a major contributor to cardiovascular morbidity and mortality

Air pollution is a complex mixture of gaseous and particulate components, each of which has detrimental effects on human health. While the composition of air pollution varies greatly depending on the source, studies from across the world have consistently shown that air pollution is an important modifiable risk factor for significantly increased morbidity and mortality.

The evidence is particularly strong for outdoor particle pollution exposure. Fine particulate matter (particulate matter with diameters less than 2.5 µm or PM2.5) can increase the risk of cardiovascular events.

Air pollution is a growing public health problem and mortality due to air pollution is expected to double by 2050

Air pollution is a growing public health problem and a leading cause of premature death and disease. According to the World Health Organization (WHO), almost all of the global population (99%) breathe air that exceeds WHO guideline limits and contains high levels of pollutants. Low- and middle-income countries suffer the highest exposures, with 2.4 to 2.6 billion people exposed to dangerous levels of household air pollution from the use of polluting open fires or simple stoves for cooking.

Outdoor air pollution in both cities and rural areas is a major environmental health problem, causing fine particulate matter that results in strokes, heart diseases, lung cancer, and acute and chronic respiratory diseases. Fine particulate matter (PM2.5) is the air pollutant driving the most significant health problems and premature mortality. In 2021, 97% of the urban population was exposed to concentrations of fine particulate matter above the health-based guideline level set by the World Health Organization.

The health impacts of air pollution are far-reaching, affecting every major organ in the body, including the heart and circulatory system. Both acute and chronic exposure to fine particulate matter air pollution is associated with an increased risk of death from cardiovascular diseases, including ischemic heart disease, heart failure, and ischemic/thrombotic stroke. Particulate matter has also been linked to the development of metabolic diseases such as obesity and diabetes mellitus, which are themselves risk factors for cardiovascular disease.

The evidence for the detrimental effects of air pollution on cardiovascular health is extensive. Epidemiological studies have consistently shown a link between particulate matter air pollution exposure and adverse health outcomes, with the first reports dating back to the first half of the twentieth century. More recent studies have shed light on the biological mechanisms by which particulate matter exerts its toxic effects, including inflammation, oxidative stress, atherosclerosis, thrombosis, endothelial dysfunction, hypertension, cardiac remodeling, and arrhythmia.

The impact of air pollution on cardiovascular health is expected to worsen, with mortality due to air pollution projected to double by 2050. Addressing this growing public health crisis requires both policy interventions to reduce air pollution and individual efforts to limit exposure, particularly for those with pre-existing cardiovascular disease.

Reducing the effect of air pollution on public health will require both policy efforts to reduce production of air pollution as well individual efforts to limit exposure, particularly for those with preexisting susceptibility to cardiovascular disease
