PM2.5与心血管疾病

一、 可以诱发血管内皮病灶的形成

                             Premature death, especially due to cardiovascular effects

  Breathing in fine particles can cause death by harming the heart and blood vessels.

This includes changes in the way the heart and blood vessels function, which can lead to heart attacks, stroke, cardiac arrest, and/or congestive heart failure

Nonfatal cardiovascular events, such as heart attacks and strokes, as well as increased hospital admissions and emergency department visits for congestive heart failure and ischemic heart disease (reduced blood supply to the heart).
For example, breathing in fine particles can: Trigger inflammation and alter blood vessels, which can include clogging arteries (atherosclerosis) or forming blood clots. These changes can result in a reduction in the supply of oxygen and nutrients to the heart - and subsequently, lead to a heart attack. Alternatively, clogged arteries and clots may prevent blood from getting to the brain, resulting in the brain not receiving enough oxygen to function – and subsequently, lead to a stroke.

除此之外，最近发表在Plos Medicine的研究表明，PM2.5可以使动脉血管壁增厚。

二、 诱发流产

三、增加癌症发病率

四、 肺炎加剧

Respiratory effects in children, such as reduced lung development and the development of chronic respiratory diseases, such as asthma
