Cardiovascular effects of air pollution

Cardiovascular effects of air pollution.

Air pollution is a heterogeneous mixture of gases, liquids and PM (particulate matter). In the modern urban world, PM is principally derived from fossil fuel combustion with individual constituents varying in size from a few nanometres to 10 microm in diameter. In addition to the ambient concentration, the pollution source and chemical composition may play roles in determining the biological to...

How nutrition might modify the possible effects of air pollution on cardiovascular diseases risk?

Epidemiologic evidence of cardiovascular effects of particulate air pollution.

In the past decade researchers have developed a body of epidemiologic evidence showing increased daily cardiovascular mortality and morbidity associated with acute exposures to particulate air pollution. Associations have been found not only with cardiovascular deaths reported on death certificates but also with myocardial infarctions and ventricular fibrillation. Particulate air pollution expo...

The effects of air pollution on cardiovascular diseases: lag structures.

OBJECTIVE To assess the lag structure between air pollution exposure and elderly cardiovascular diseases hospital admissions, by gender. METHODS Health data of people aged 64 years or older was stratified by gender in São Paulo city, Southeastern Brazil, from 1996 to 2001. Daily levels of air pollutants (CO, PM10, O3, NO2, and SO2) , minimum temperature, and relative humidity were also analyz...

Cardiovascular effects of air pollution: what to measure in ECG?

Epidemiologic evidence indicates that air pollution adversely affects the cardiovascular system, leading to increased cardiovascular morbidity and mortality. However, the mechanisms of such an association are unknown. Although potential mechanisms of deleterious effects of air pollution may involve response of the respiratory system, immunologic response, or coagulation abnormalities, the cardi...
