We essentially live in our blood vessels and age in our arteries.CAD is the principal  cardio vascular disease, which  God has created in Homo-sapiens to ensure they  do not stay more than “allotted life span” in this planet. Of course , the current generation cardiologists equipped with scientific weapons , have since decided to take the fight directly in the Almighty’s domain .Contrary to the popular medical doctrine, treating an established CAD seems to be easier task than preventing a new onset CAD.

While , arteriosclerosis is a normal aging process, atherosclerosis could be an  aging as well as a distinctive pathological process. However , athero-thrombosis  is a definite pathology of vessel wall .We know at any time atherosclerosis  can transform into  athero-thrombosis  and result in  clinical event depending upon the  triggers and other associated conditions, which we refer to as major or minor  risk factors.

In scientific terms ,

  • Primary prevention  of CAD is preventing first episode of  Coronary  event*(Typically , CSA, STEMI/UA,NSTEMI/SCD,)
  • Secondary prevention  is  prevention  of  second  or subsequent episodes following the first clinical event.(*What if , if  the first event is silent and never known ? )

For all practical  purposes CAD and  coronary atherosclerosis is synonymous. Can we  prevent atherosclerosis in human biological system ?  What are we  supposed to refer to  such a preventive measure , if any ?

We are biased towards obstructive CAD as we often  think it is the  the only form of CAD .Then , how do we diagnose , treat and prevent a minimal non flow limiting plaque , coronary endothelial dysfunction , or  acute coronary erosion that can occur in very early stages of atherosclerosis, in other wise healthy persons.(Routine IVUS ,OCT ? Futile isn’t )

  • Preventing  sub-clinical  CAD  from manifesting  as clinical CAD , is technically   primary prevention”  but still  patho-biologically  secondary prevention.
  • Preventing a CAD in a patient  with peripheral vascular  disease  or preventing CAD in a patient with TIA or stroke is secondary prevention for cerebrovascular disease but  falls within the definition  of primary prevention of  CAD.
  • Then  comes the new semantics :Primordial prevention .This could be same as primary (or another  version of primary prevention ).Primordial prevention is preventing development  the risk factor  itself (Like DM,HT, Dyslipidemia )

So ,whenever , we talk about primary prevention of CAD by Aspirin or Statins ,realize the complexities involved .Before i finish, let me make you  dizzy further with this quixotic one . In a multivessel CAD, as the  atherosclerotic  plaques are scattered across the coronary arteries in various stages of  maturity  , long term Aspirin  following  anterior STEMI has to secondary prevent an event  in LAD territory  . . . but   primary prevent a plaque disruption in RCA territory !

  • 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

  It costs just one Dollor !

Harvard school of Public health has  recently  published some  hard data about  the adverse effects of bad diet habits especially the impact of  soft drinks on long term cardio vascular health.

soft drinks and impact on healthAnother prestigious journal confirms it . . .

risk of soft drinks and coronary artery diseaseThe ultimate journal for the cardiologists Circulation reaffirms it .

soft drinks carbonated and coronary artery diseaseWe  have overwhelming evidence , prolonged use of soft drinks
increase CAD (Like tobacco ). Still , we haven’t added the customary caution on the bottles of these soft drinks ?

Why  ?

My guess would be, there are powerful forces in  modern society that would love to keep  the  threat of diseases high in the  human domain  so that all  stake holders  make a profit .

The poor , World health instigation(WHO)  and various public health forums  simply watch it .If they protest , they are at risk of sucked into the loop of deceit !

Failure to reverse public health hazards  may be a  lesser crime  in modern days  . . . But , here comes  a series of  advertisements in Indian media , that is a strong indicator that human  intellect and the sixth sense  is going nuts !

It suggests , Do you want  ever lasting happiness . . . Drink  it  . . . earnestly believe  in it  . . . and drink again  !

I was also told  a shocking fact that , The beverage war in India has  started and the soft drink giants have heavily Invested to take it into the rural markets .Their aim is to  provide  “health  for all Indians”  by 2020 !

Medical research   often ventures into a directionless and meaningless  exercise with or without intention .The reason is simple , unlike  other fields,  scientists enjoy  the ultimate freedom of expression.
