“ Propensity matching ” in medical research : Definitely, not made in Heaven !
It is likely, that the biggest Impact & influence in current medical research may not come from the IQ of our scientists, their concepts, or the sophistication of the laboratory. Then what? Can you guess? It is the man-made mathematic sub-specality called statistics. We are going to either ratify or reject any research work ( on which we toil) based on the quality of numbers we generate. Such is the critical value of this specialty. Just pause a moment, and think over. How much importance do we give to the credibility and “quality of the interpretation” of any study? We have conveniently left it to our este...

New skills in ACS : Lessons from an Immature resident and an Intelligent consultant !
A brief conversation between an elite consultant and his fellow. (Caution: Grade 2 harsh language)
Hey Doc, why is this guy’s name not found in today’s angiogram list? Any Insurance issues?
No sir, he has every requirement. Thrombolysis was very successful, ST has regressed well and it is nearly isoelectric and only T is inverted. His LV function is normal. In fact, I am not able to pick up any WMA.
Aren’t you aware, that being fine is never a contraindication for a PCI ? Which book teach you like that?
No sir, It’s already beyond 48 hrs sir. What is the purpose of know...

Don ’ t try to educate your patients too much.., because
This write up was triggered after encountering a patient who instructed his cardiologist to remove an incidentaly found block in Right coronary artery.
Oftentimes, It is a funny & futile world out there in modern medicine. Revealing the complete truths or accepting ignorance in critical decisions to their patients, make the Doctors feel that, their academic modesty and reputation are at stake.
Still, many patients expect (and think) the doctors to be 100 % transparent and want to understand the nuances of disease better than the doctors themselves. The current fad of online & offline health educat...

Cardiac Holography : Lets get ready to welcome, in our cath lab soon !
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,...

Bifurcation PCI : Physics & Philosophy of DK crush technique
Bifurcation PCI is a modern-day Cardiologist’s fascinating professional adventure within coronary arteries. Of course, the Intention is to do good for the patient. Bifurcation lesions (BFL) are a special subset of lesions, that looks challenging, more because of the potential biological aftermath following the delicate construction of a grade separator at a critical site. Mind you, it’s done within a live flowing artery and subsequently needs lifelong maintenance.
Strategies for BFL

Duroziez ’s murmur : A simple bedside marker of diastolic descending Aortic flow reversal & VTI
Murmurs are audible noises from within the Heart or vascular tree when blood flow loses its laminar flow and becomes turbulent. There are many factors responsible for it (Recall Reynold’s number ).It is obvious, that when there is hyperdynamic circulation, even in physiology one may hear a murmur. Pregnancy is a classical example and Innocent (still murmur) in children is another one.
Duroziez murmur: A brief history
In this post let us dwell on something about a classical murmur that occurs in the peripheral circulation away from the action-packed organ heart. It was originally described by French physician Dr...

Is there Intracellular edema in congestive heart failure ?
I am unable to answer this question confidently even after spending 25 years in the specialty of cardiology. I thought, the answer was yes. Reality is definitely different. Such is the complexity in the biology of the fluid and circulatory systems. The heart’s function doesn’t seem to end with just pumping 6 liters of blood every minute, ultimately, it has to handle a huge load of water as well with delicate coordination with the kidney. (ANP,& RASS feedback). It is fascinating to note, that the heart transforms into a powerful endocrine organ as and when it is necessary.

How is RCA angina different from LAD angina ?
William Heberden first introduced the term angina to the medical community in 1778. His descriptions became immortal. Still, no one would ever know what was the angina-related artery, Heberden was alluding to.
Now, some jobless cardiologist is asking this question after 200 years. How is angina from the LAD system differ from the RCA system? or let me put it another way, How does angina of anterior circulation (LAD) differ from posterior circulation (RCA/LCX)? Though there is distinct hemodynamic profiling of RCAvs LAD ACS, surprisingly, cardiology literature does not answer the chest pain aspect of it. One rare stud...

When to revascularise in stable CAD: A Single slide presentation
This graph is a rare treasure in CAD therapeutics (fished out from essentially meaningless, often dangerous statistical curves littered in chronic CAD literature) that elegantly shows us the complexities involved in the revascularization of ischemic hearts with risks and benefits criss-cross each other. Our job is to identify, that critical point in a given patient’s CAD timeline. To make things difficult, this point is a moving target and makes this delicate clinical exercise truly complicated.

Be happy with the “ H ” Index of Hippocrates
“Publish or perish “
This sound bite is regularly uttered by all academic leads in any university or medical school. I don’t know, why this bothers me. Looking back, many of our mentors & professors never had any great publications. Still, they were extraordinary teachers and wonderful clinicians with great wisdom. They created generations of high-quality doctors who are present all over the globe now. Is scientific publication that important in a doctor’s life? After pondering for quite some time, got a hazy answer to that query in one of my sleepless early morning academic dreams.
