Reducing personal exposure to particulate air pollution improves cardiovascular health in patients with coronary heart disease.

ABSTRACT:

Background

Air pollution exposure increases cardiovascular morbidity and mortality and is a major global public health concern.

Objectives

We investigated the benefits of reducing personal exposure to urban air pollution in patients with coronary heart disease.

Methods

In an open randomized crossover trial, 98 patients with coronary heart disease walked on a predefined route in central Beijing, China, under different conditions: once while using a highly efficient face mask, and once while not using the mask. Symptoms, exercise, personal air pollution exposure, blood pressure, heart rate, and 12-lead electrocardiography were monitored throughout the 24-hr study period.

Results

Ambient air pollutants were dominated by fine and ultrafine particulate matter (PM) t
