Cardiovascular Disease and Fine Particulate Matter

A Case-Crossover Study between Fine Particulate Matter Elemental Composition and Emergency Admission with Cardiovascular Disease.

BACKGROUND It is generally understood that Fine Particulate Matter (PM2.5) can cause high blood pressure. However, it remains unclear whether there is a relationship between the elemental composition of PM2.5 and cardiovascular disease in emergency department patients. METHODS Crossover design for time stratified cases and conditional logistic regression were used to analyze the correlation b...

AHA Scientific Statement Particulate Matter Air Pollution and Cardiovascular Disease

In 2004, the first American Heart Association scientific statement on “Air Pollution and Cardiovascular Disease” concluded that exposure to particulate matter (PM) air pollution contributes to cardiovascular morbidity and mortality. In the interim, numerous studies have expanded our understanding of this association and further elucidated the physiological and molecular mechanisms involved. The...

Particulate Matter (Fine Particle) and Urologic Diseases

Particulate matter (PM) has been found to damage vital body organs, including the lungs and heart, through vascular damage and oxidative stress. Recently, renal function and chronic urologic diseases have also been found to be related to PM. To investigate this, we reviewed the characteristics of PM related to renal toxicity, including recent studies on the associations of urologic diseases wit...

Hormesis for fine particulate matter (PM 2.5).

The hypothesis of hormesis - that substances that harm health at high exposures can reduce risks below background at low exposures, e.g., if they activate defenses without overwhelming them - becomes important for practical policy making if it holds for regulated substances. Recently, the U.S. EPA concluded that reductions in ambient concentrations of fine particulate matter (PM2.5) in air caus...
