     The greatest discovery in medicine is  “ common sense” and

    “democracy”.           

                       The greatest medical discovery  is the realization that medicine is an constantly evolving science. It needs lot of knowledge to know our ignorance . Common sense has probably saved more lives and reduced suffering in this world than any other single discovery. Note this glaring irony ! It has required a large multi national long term follow  up study (INTERHERT) to prove exercise and physical activity is good for health. Whatever science is teaching us it is we, with our sixth sense have to act appropriately .It is the only defense against the potential exploitation against man kind by various forces.

Another great development is the freedom of expression and democracy in medicine,  for which journals like BMJ, Internet are striving hard . . .

CURRENT   CARDIOLOGY  PRACTICE: EVIDENCE  OR  EXPERIENCE  BASED ?    AN  ANALYSIS OF  ACC/AHA  GUIDELINES.

S. Venkatesan,  Madras Medical College. Chennai

 

If  a  major therapeutic procedure is adviced based on simply by experience or expert opinion  how can we say evidence based medicine is practiced !

 

                                    Evidence based cardiology  is  the  buzz word  in global cardiovascular  health care  organizations. All diagnostic  and therapeutic  interventions are  undergoing  rigorous randomized  trials  for  proof of  efficacy  and  safety. ACC/AHA   have published  management guidelines and it  has been accepted  as de-facto standard of clinical cardiology practice world wide.  In these guidelines  class  1  indication  is defined as Conditions for which there is evidence for and/or general agreement that the procedure is useful and effective. These indications are supported by three levels of evidence.(A,B,C) .It has been observed,   many of the recommendations  in  class 1  were supported by only level  C  evidence. (Expert consensus or  agreement  ). We  analysed how much of todays guidelines is  agreement based  and  how much is evidence based. The  latest  practice  guidelines  of  ACC/AHA   for  Acute myocardial infarction , Unstable Angina and Non–ST-Segment Elevation Myocardial Infarction , chronic  stable angina  ,coronary angiography  were analysed. The  no  of  class 1  indications  were counted  in each set of guidelines  and  each  of the indication were  sub grouped with reference to the  levels of  evidence  to which it was supported. There  were a total  of 210  class 1  indications.

 13.9%   of class 1  indications were based on  level  A evidence.  42.4%  of class 1 indication were based  on Level C  ( agreement  of experts).Though evidence based cardiology   is   considered  to  define  the  standards in  Cardiology  practice  in reality  we lack evidence in most of the situations. 

                                       We  conclude  that  consensus or  agreement  based cardiology  practice is the dominant theme in current   ACC/AHA

Peer review of an article even in major journals never scrutinise the “Aim of  a study ” . However big is the journal,  they seem to bother only about the authors, materials, methods, and statistical analysis.  If only they peer review an article , right from the “Aim of the study” like ,

  • Who asks the research questions?
  • Who  defines the aim of the study ?
  • Who decides which drug to be compared with which drug ?
  • Who steers the steering commitee of a trial ?

If only , we could answer these questions without bias , pharma industry and their  regulators  would have ,  far more better image than what they have now !

A typical example for , the aim of the study  to be  wrong  , is  the “ONTARGET’ study on telmisartan.

Here they ( Who ? ) raised an inappropriate  question of     “Non inferiority” of one drug with other  without any  valid reason to compare these two drugs that will benefit the man kind !

Infective endocarditis  remains a  major cardiac emergency.

Medical management has an initial role and  the many will require some form of surgery

( Mainly valve  replacement). But the surgeons request a realtively stable patients to operate upon as

surgical mortality is high in patients with uncontrolled infection and destabilsed CHF.

Even though there are battery of antibiotics, and volumes of texts written on the medical management

of infective endocarditis the medical therapy fails in bulk of the patients.

We have observed  emprical (Scientific guess work ) therapy has helped many patients .

While rifampicin according to scientific worls it’s useful only in prosthetic valve endocardtis

we have found it quiet useful in all resistant IE patients.

IE being a chronic inflammatory state rifampicin might work 

also as an anti inflammatory or immune   modulator.
