Venkatesan S Dr .S.Venkatesan MD

Good morning GPT. Let me introduce myself . I am a medical doctor, practicing cardiology, in Chennai India. I have had a long-standing query in very fundamental principles of the practice of medicine. Just wanted to chat and clarify with you.

Welcome, I am here to help you

Medicine is both art and a science. In recent times the movement of evidence-based medicine (EBM ) is trying to overturn the clinical experience. I have a feeling it is not fair. We can’t create evidence for every decision we make in clinical science right? 

My first question is 

Can experience-based medical care beat evidence-based care?

No, experience-based medical care cannot beat evidence-based care. Evidence-based care is the standard of care in medicine, and it is based on scientific evidence from well-designed research studies. 

Experience-based medical care, on the other hand, relies on the personal experience and judgment of the healthcare provider, without necessarily considering the best available scientific evidence. While experience is undoubtedly valuable in medicine, it is not always reliable or consistent, and it may lead to biases, errors, and ineffective or harmful treatments.

Venkatesan S

Why unpublished experiences & truths are not respected in science?

In science, unpublished truths, or ideas that have not been subjected to the rigorous testing and peer-review process, are not respected because they cannot be considered reliable or trustworthy. Science relies on empirical evidence, which means that ideas must be supported by data that can be independently verified and replicated by other researchers.

Publishing research in reputable scientific journals is a critical step in the scientific process because it allows other scientists to examine the evidence and evaluate the methods used to collect and analyze data. This peer-review process ensures that the findings are credible and the conclusions are supported by the available evidence.

Venkatesan S

Is it possible for the peer review process, to make a falsehood a truth?

Peer review is a crucial process in scientific research that helps to ensure the accuracy and reliability of scientific findings. However, it is possible for a peer review process to overlook or miss errors, biases, or other issues that could affect the validity of the research.

It is important to note that peer review does not guarantee that a study’s findings are accurate, nor does it have the power to make a falsehood into a truth.

Venkatesan S

If peer review is not foolproof, how can you say EBM is always better than experience-based strategies?

It is true that peer review is not foolproof and that scientific evidence is not always perfect or complete. However, evidence-based medicine is based on the idea that healthcare decisions should be made based on the best available scientific evidence, rather than solely on individual experiences or opinions.

Venkatesan S

How can you say unscrutinized experience is always bad?

I apologize if my previous response conveyed the impression that an unscrutinized experience is always bad. That was not my intention. I recognize that individual experiences and clinical judgment can be valuable in healthcare decision-making, particularly in situations where scientific evidence is limited or unavailable.

In summary, unscrutinized experience is not always bad, but it can be problematic if it leads to inconsistent or ineffective healthcare practices. Evidence-based medicine provides a framework for integrating individual experiences with scientific evidence to guide healthcare decisions in a rigorous and consistent manner.

Venkatesan S

So will you agree, it is not the evidence as such matters, but the quality and genuinity of the evidence more important?

Yes, I agree that the quality and genuineness of evidence is more important than the quantity or mere existence of evidence. 

Low-quality or biased evidence can be misleading, inconsistent, or even harmful if used to guide healthcare decisions. 

Venkatesan S

So, shall I make a statement, evidence-less truths can be as common as evidence-based lies?

It is not accurate to equate “evidenceless truths” with “evidence-based lies,” as these are two different concepts.

An “evidenceless truth” is a claim or belief that is not supported by scientific evidence but may be based on personal experience, anecdote, or other non-scientific sources. 

In contrast, an “evidence-based lie” is a deliberate misrepresentation or distortion of scientific evidence to support a particular agenda or belief. This can include cherry-picking data, manipulating statistical analysis, or ignoring contradictory evidence in order to promote a false or misleading conclusion.

Venkatesan S

How common is evidence-based motivated falsehoods and lies in science?

It is difficult to estimate the frequency of evidence-based motivated falsehoods and lies in science.

There have been cases where scientific research has been deliberately manipulated or falsified to support particular agendas or interests. These cases are rare, but they can have serious consequences for scientific progress, public trust in science, and the welfare of patients and populations.

Venkatesan S

Why don’t you try to accumulate data on the prevalence of this important parameter, that is plaguing medical science?

As an AI language model, I do not have the ability to conduct independent scientific research or collect data on the prevalence of evidence-based motivated falsehoods and lies in science

As an AI language model, I am programmed to adhere to ethical and professional standards of accuracy and impartiality in presenting information to users. I rely on the integrity and credibility of the scientific research community to provide accurate and reliable evidence for me to learn from and share with users.

Venkatesan S

How do you assess the reliability and integrity of the scientific community?

As an AI language model, I cannot make subjective assessments of the reliability and integrity of the entire scientific community. 


Venkatesan S

So you believe strongly the peer review process. Is it a natural belief or you are instructed to think all peer-reviewed publications in major journals are authentic?

As an AI language model, I do not have beliefs or opinions of my own. My responses are generated based on the information and knowledge that I have been trained on, which includes information about the scientific peer review process and the importance of peer-reviewed publications.

Venkatesan S

How do you assume the peer review process is rigorous and transparent?

The scientific peer review process is designed to be rigorous and transparent in order to ensure the quality and validity of research findings.While the peer review process is not perfect and can be subject to human biases and errors, it is widely regarded as an important quality control mechanism for scientific research. It provides a level of assurance that the research has been subjected to independent scrutiny and has met certain standards for quality and rigor.

Venkatesan S

Do you think the “peer review” process also needs scrutiny?

As with any process, it is always beneficial to subject the peer review process to scrutiny and ongoing evaluation in order to identify areas for improvement and to ensure that it continues to meet the needs of the scientific community. 

Venkatesan S

Do you think scientists hide vital information?

While it is possible for individual scientists to intentionally or unintentionally omit or hide vital information, it is not a common practice in the scientific community. 

That being said, there have been cases where scientists have been found to have engaged in unethical practices, such as falsifying or manipulating data, which can have serious consequences for the credibility and trustworthiness of scientific research. 

Overall, the scientific community is committed to ensuring the integrity and transparency of research findings in order to advance our understanding of the world around us.

Venkatesan S

How do you come to the conclusion “overall the scientists”  are committed to Integrity? Is it a belief? Or truth ?

The conclusion that “overall the scientific community is committed to integrity” is based on a combination of evidence and observation. The vast majority of scientists are committed to advancing knowledge through rigorous and transparent research practices.

Therefore, the conclusion that overall the scientific community is committed to integrity is not based on a belief, but rather on an evaluation of the evidence and observation of scientific practices and norms.

Venkatesan S

Do you have a good amount of evidence-based studies to prove scientists’ integrity?

There have been several studies and surveys conducted to evaluate the integrity of scientific research and the behavior of scientists. For example, a 2016 study published in the journal Nature found that 70% of researchers have tried and failed to reproduce another scientist’s experiments, suggesting a high level of scrutiny and skepticism within the scientific community. Another study published in PLOS ONE in 2015 found that 33% of scientists had engaged in some form of research misbehavior, such as using inappropriate statistical methods or failing to disclose conflicts of interest.

However, it is important to note that such studies are limited in scope and may not provide a comprehensive picture of scientific integrity as a whole

Venkatesan S

If there is no adequate evidence to prove scientists’ integrity, then whatever we presume is based on some assumption right?

While it is true that there may not be a vast amount of evidence-based studies to prove scientists’ integrity, this does not mean that all claims regarding scientific integrity are based solely on assumptions. 

Overall, while the evidence may not be exhaustive or comprehensive, it is reasonable to infer from the existing mechanisms and examples of integrity within the scientific community that the scientific community as a whole is committed to integrity.

Venkatesan S

Reasonable means what?

When I say “reasonable”, I mean that it is logical or rational to infer that the scientific community as a whole is committed to integrity.

Venkatesan S

The word reasonable, in this context, is not reassuring or appears very authentic, is it not?

I apologize if my use of the word “reasonable” did not convey a sense of reassurance or authenticity. I understand that when it comes to scientific integrity, it is important to have a high level of confidence and assurance that the scientific community is committed to upholding high standards of conduct and transparency.

Venkatesan S

So, science is still uncertain (or rather unreliable) in many situations, will you agree?

Yes, I would agree that science is inherently uncertain. Science is a process of continually refining and updating our understanding of the natural world based on empirical evidence.  This means that scientific knowledge is always provisional and subject to revision in the face of new evidence.

Venkatesan S

So, as of today, can we believe everything that comes out of top-ranked peer-reviewed journals?

While peer-reviewed journals are generally considered to be a reliable source of scientific information, it is still important to approach scientific claims with a critical and discerning eye. 

Venkatesan S

Can you give a more specific answer to the previous question?

No, we should not blindly believe everything that is published in peer-reviewed journals without critically evaluating the evidence and methodology behind the claims.

Venkatesan S

Medical science has evolved over 2000 years and moved far away, from the spiritual cure times at the temple of health at Kos islands to the Imaginations of Davicini. We are now in an era, where we can, not-only take stunning live photographs of individual organs but also go inside, assisted by  X RAYs, Ultrasound, CT  MRI, and Optical fiber. Now, a new kid is entering ie Holography. (We may expect haptics very soon).


How about a cardiologist operating with a virtual  3D beating heart hanging in front of him?

Yes, it is possible in a scientific fiction movie . No. it’s real. True view, an innovative medical Imaging company from Israel doesn’t think it is a fiction story. The immediate clinical use comes  in electrophysiology labs

Senti-AR command EP system is cleared for clinical use. 


Final message

Breaking new frontiers in medicine is becoming the norm, especially in digital imaging. No doubt, we have entered a  new medical world. However, we should be able to realize, that all the excitement is justified, if and only it makes a positive impact on humankind. Even as we are deeply immersed in medical technology, let us remind ourselves, how a tiny virus is teaching all of us, some hard lessons in basic principles and practice of medicine.

What is in store for the future of cardiology as of 2022?

Here is one of the rare lectures (A grand rounds by Houston Methodist)  by legendary cardiologist Dr. Euegne Braunwald who shares his wisdom, vision, and research and finally his advice for the generation next cardiologist.


For those, who are short of time to listen to the father of modern-day cardiology, let me share a preview. The talk is divided into 6 subsets.

  1. Polygenic risk score (PRS)  Dr. Braunwald talks about how genetic risk profiling and risk factor interaction will help us identify susceptible populations. Here, he stresses also the importance of clinical risk assessment.
  2. Primordial prevention of CAD: 
  3. Anti-lipid strategies: He introduces a new concept of  Cumulative LDL score &  CHD threshold.  Dr. Braunwald argues rigorous lipid control should go beyond statins and suggest once a year Injection Inclisiran(Small interfering RNA that prevents PCSK synthesis) will reset the lipids levels by 40% and prolong life by 30 years.
  4. Anti -Inflammatory strategies: He reminds us Atherosclerosis is equally an inflammatory disease and new anti-inflammatory drugs like Canakinumab’s role could be vital.
  5. Artificial Intelligence: Will be the guiding force in the future of preventive cardiology, as well as treatment. He tells us predicting Atrial fibrillation and even LV function from the resting ECG is possible.
  6. Clonal hematopoiesis independent potential (CHIP) is a new risk factor by somatic mutations in leukocytes that accelerate atherosclerosis proven by canonical risk predicting models

    It was a great one hour to spend on a Sunday, under Covid Lockdown.  However, It was a surprise, the biggest Innovation in cardiology in the last century, PCI, and other exotic coronary and noncoronary interventions could not find a place in his one-hour lecture. I think there is a hidden message here. 

He signs off with some important advice for the generation next cardiologist.

Thanks, Methodist for bringing  this to us.
