Some of the noise bites from a busy cath lab after a  mid noon angioplasty

         Oh’  that  looks bad , whats that projecting !

There is some haziness too ,

            Make sure its not a flap,

  Better to do IVUS or should I OCT ?

           Shall I  post dilate with NCB ?

Should we cover with  another stent ?

           I think we can manage with Tirofiban or Reopro 

Call the chief ! suggested a first year resident,that seemed to be the most reasonable noise bite among all .Yes, the final command came from the chief cardiologist after a 10 second glance over the workstation ,”Guys,  forget it , . . its acceptable  pinching, DAPT will take care of it , just ensure adequate ACT till night , put the next case . . .on table” !

That’s fairly common chat session in any high volume cath centres (Which ended abruptly  in this case with the chief’s uttering)

Does any body know  what the chief meant by  the term pinching ?

  • Is it the  pinch of Intimal fold ?
  • Is it pinch of plaque ?
  • Is it a flap ?
  • Is it a plaque prolapse within the strut ?
  • Or just a evaginated thrombus
  • A subintimal calcium speck ?
  • A longitudinal stent deformation?

Any one knows the histology ? Is there any natural history  study of such pinching ?

Iam afraid no one knows . But common sense tell us it can be anything  between a totally benign entity to  Imminent nidus  for an acute stent thrombosis , depending upon the patient’s destiny and physician’s luck !

How does one make a decision in such an uncertain situation ?

The decision to leave that pinching is taken by any  cardiologist  based on his past experience or  Inexperience or both. Some do IVUS/OCT , many don’t . Whatever the decision  ( empirical or scientific ) its  going to be tentative  and  outcome is any body’s guess.

Final message

Coronary arterial pinching is a dangerous cath lab slang used exclusively by expert Interventional cardiologists , often after a hurried PCI ! It may sound  innocuous .To label a protruding plaque as a “safe pinch”demands heavy courage that is an essential requirement  for a successful Interventional  cardiologist , which most of them are blessed with !

Reference 

1.No Reference as such :There is no specific study about histology of coronary pinching  .Though , IVUS and OCT data are available for various post PCI shadows , it never addresses the issue of pinching specifically as no one is clear about what they mean by it.  Hence ,we are planning to decode this long pending mystery with our own  PINCH-iVUS  study.

2.This article from Circulation Imaging  new generation IVUS could reveal  histology of pinching

Professional competence is defined as doing things, always in the Interest of patients. It’s generally believed small hospitals are not competent enough to treat cardiac emergencies . . .Do you agree with that ? No, Its largely a myth . Do you know there is a absolute  lack of proficiency  threatening to plague our country’s coronary care system. ? It’s the professional  Incompetence by the space age, star hospitals (mis)managed by masters of the noble business. None (am I right ?) of this hospitals either monitor or publish the outcome of their treatment.

Backed by pseudo scientific data , amplified by unrealistic expectations of ill Informed patients , some  hospitals are avoiding Initial emergency treatment of acute MI  , instead they waste time ( load DAPT ofcourse !) in securing the finance  for the costly Invasive procedures or refer them out of their premises if they can’t afford for it.In the ensuing emotional and financial melee many of the ill-fated patients lose vital  time window of thrombolysis as well ! and carry risk of fatality or damaged myocardium.

Every stake holder in the current  coronary care system simply assume the enforced modality  must be far superior because they administer the most modern and costly treatment suggested by few high intensity cared clinical trials originating from west. The wisemen who run the corporate hospitals  never realise medical competence and outcome is not entirely defined by science. Their primitive cognition wouldn’t allow to think beyond business equations either.

Please believe me, time and again, I have witnessed patients reaching Government hospitals  after being shunned away by  big (Some times even medium sized )  hospitals who boast themself only as PCI enabled care. Even if they want to lyse they stock only the Tenekteplace .

I think tragedy  is a lesser word to describe the scenario , where a distressed family is trying to arrange  for a Rs30,000 shot of Tenekteplace when thirty times cheaper still equally efficacious (Rs 1000 Streptokinase)  is concealed from their visibility .The Govt should urgently look into instances of large private hospitals avoiding Govt insurance scheme patients  even in  cardiac emergencies ! To label our poor patients as unaffordable ones is a outright misnomer, rather its the rich hospitals that are “not affordable” to lose profit and treat our countrymen , in a cost effective manner is the reality !

Who is Poor ? You decide.

Two forbidden things in coronary care

 1.Cajoling  and manoeuvring a distressed  family for a primary PCI as a routine treatment  hyping its beneficial effect and underplaying the true advantages of thrombolysis in largely technical jargons is the current norm in most coronary care units.

2.Another issue is , after confused confabulations with the duty medical officer,  if a rare patient family  choose the option of thrombolysis , comes the next googly*.  Many noble minded hospitals do not stock the low-cost and equally efficacious thrombolytic agent and offering  only the costly option to the anxious families when the myocardium is on fire.

Hospitals that  practice these two coronary protocols  need to be shamed and labeled as  “Coronary Incompetent  ” In spite of having 24/7 cath labs.  (Realise , they are just like  any remote rural hospitals , at least  the later can’t be faulted  as they don’t  withhold  a  reperfusion strategy  !)

Final message

I think , mindless proliferation of cath lab based cardiac care , which follow this theme , ie  “Thrombolysis incapable but PCI capable “ are  biggest threat to coronary care in our country ! For the best coronary care for any country ,what we need is efficient prehospital thrombolysis team .We have conveniently forgotten the great study of CAPTIM wherein the ambulance drivers replicated the same effect of primary PCI performed by highly trained cardiologists in modern labs.

In India,  primary health centers which is within  few km reach of entire population  can be designated as static ambulance equivalents  with basic resuscitation facility . If a multipurpose health worker can be trained to lyse, with remote supervision that will accomplish  90 % of what the cathlab guys can achieve ! Selective shifting is suffice.

Postample :  Ofcourse, not doing  pPCI for high risk or complicated STEMI is unscientific and we need to have proper consenting and referring frame-work for such patients.

Counter point : One of my colleagues asked me ? Why do I enjoy attacking the established scientific practices ?  May be I have a problem , yes, but  I think in a  true medical democracy we have right to debate anything , absolute truth is a ongoing journey !
