  • Diabetes , smoking , hypertension , dyslipidemia are the  leading cause of cardiac morbidity and  mortality .
  • Now air pollution the(  passive atmospheric smoking !) is threatening to be a major risk factor .
  • In fact , it has become the  official  cardiac risk factor nominated by WHO !
  • 40 %  of all deaths due to air pollution is due to cardiac events .
  • The surprise element is indoor air pollution is equally injurious .

WHO bulletin  in March 2014

air pollution and cardivascular health

The WHO assessment found the majority of air pollution deaths were linked with cardiovascular diseases.

For deaths related to outdoor pollution, it found:

  • 40% – heart disease
  • 40% – stroke
  • 11% – chronic obstructive pulmonary disease (COPD)
  • 6% – lung cancer
  • 3% – acute lower respiratory infections in children

For deaths related to Indoor pollution, it found:

  • 34% – stroke
  • 26% – heart disease

Coronary artery disease  can be termed  as   “New age plague” afflicting the mankind  !  It  probably has killed ( or Killing ) as  many lives  as   most other diseases  put together.  Why  only a section of  our  population is vulnerable is  not fully  understood .

We are familiar with coronary risk factors for too long  . . . still  . . .

We do not understand why 50% CAD occur in people who have no known coronary risk factor !

There has been propositions and dispositions  of various risk factors .  The latest one is  the  Air pollution. This is quiet interesting,  as air is the staple food of human survival . We  eat , drink ,  (Rather inhale )  about 500 ml /of  air every   3  to 4 seconds  for 24 hours a day for 365 days  , for our life time !

Does the air we breath reach the  largest cardiovascular  organ namely the vascular endothelium ?

Yes definitely  ,  not only it  reaches   the endothelium but also injures it  (When it contains gases other than oxygen  )  .While tobacco  is a well established  endothelium  destroyer , it is no surprise   community smoking ( Air pollution !)  will do the same job  with perfection .

What are the proposed toxins in the air pollution that harm the endothelium ?

It is a mixed  masala gas out there  over  our   polluted cities ! .(Atmosphere,  Industrial, Automative ,Domestic, Human , and other invisible  sources ) We need to analyse further to answer this question authentically .

Though , common sense  is  enough   to establish the  link between air pollution and CAD. We have  lots of evidence coming up  . . .



Further research

We will be shortly reporting our experience with endothelial  function assessment  in traffic police population of our city Chennai  ,India .
