Connection between air pollution and cardiovascular diseases

From American Heart Association | Aug 11, 2012

     According to Dr. Russel Luepker, Mayo Professor at University of Minnessota, cardiologist and epidimiologist,  air pollutants may cause rapture of plaque in patient with athesclorosis triggering heart attack.  PM 2.5, the invisibile nano particles from combustion engines, enter the lungs, embed in the RBC and eventually irritate the lungs, and the blood vessels around the heart.  (inflammatory effect on the heart and blood vessel.  So, high lipid level is not the sole culprit?)


From Science Daily | June 5, 2012

       Heart patients living in high pollution area were 40% more likely to have second attack, compared to those who do not, according to research of Dr Gariv Gerber of Tel Aviv University School of Public Health.  Those who were exposed to pollution were 35% more likely to die within the 20 year period after the first attack (Whew)

From How Stuff Works - Can Air Pollution affect heart health?

     Yes it does.  When the oxygenated or blood with carbon monoxide, sulfur oxide and other particulates enter heart (left atrium) these affect the heart, in the same manner they affect the lungs. Carbon monoxide, because of its limited oxygen carrying capacity, starves the heart;  particulates from diesel exhaust constricts blood vessel.  Exposure to air pollution also decreases the hearts ability to conduct electrical conduction (from SA to VA node) known as ST segment depresssion

      AHA also says that exposure to air pollution speeds up plaque build up.

     Air pollution causes heart attacks and death, according to study made by Rice University. Researchers investigating heart attacks of 11,677 patients in Houston TX area between 2004 and 2011 showed heart attacks occurence increased by 4.3% during peak pollution
