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.

Futuristic cardiology: Fishing a failing heart !
A path-breaking research is coming up from Jhon Paulson school of engineering, Harvard.
It is all about a tiny lab-made bio-hybrid fish that is mechanically engineered with cardiac stem cells. It can generate enough mechanical force that can transform into a biological organ (or assistance)to the heart. Early lab experiments are exciting. We will soon see a stem cell-enriched bio-fish that will dance to the tunes of the cardiac cycle.
(See the video below)

Curve of wisdom in ACS : Open Cath lab doors may mean nothing , if the windows are closed !
“We have a 24/7 cath lab with an open door policy. Our cardiologist arrives at 15 minutes’ notice. Door to balloon time is less than 60-90 minutes”,
“Great, so, you can always offer a successful treatment for STEMI”
“No, that we can never guarantee.”
“Oh, It Is not the answer, I expected”
“I agree, it sounds disappointing, but. truths are less pleasing. What I am trying to say is, there are a number of factors other than the availability of a grand cath lab and agile and effortless hands, that try to reperfuse the myocardium in distress. I ...

“It needs both. obviously”.

Testing times for EBM : NEJM gets ready & begins a new journey
The New England Journal of Medicine (NEJM) the premier journal in medicine originated two centuries ago, in 1811, when John Collins Warren, a Boston physician, along with James Jackson, submitted a formal prospectus to establish the New England Journal of Medicine and Surgery and Collateral Branches of Science as a medical and philosophical journal.
Subsequently, the first issue of the New England Journal of Medicine and Surgery and the Collateral Branches of Medical Science was published in January 1812. In 1921, the Massachusetts Medical Society (MMS) purchased the Journal for US$1 and, in 1928, rename...

Dr Braunwald ’ s Grand rounds on future of cardiology
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.

In AF why the ventricular rate is irregular?
Here is a case report from Dr. Brugada’s group. What is your diagnosis?
Source & Courtesy Sergio Richter, Joseph Brugada et all , 100(1), 154–156. doi:10.1016/j.amjcard.2007.02.067
Whoever diagnosed AF in the above ECG need not feel bad. The rhythm is not AF, though it mimics very closely. In cardiology, especially in electrophysiology, we can get surprises on a daily basis. (Read below)
Why the ventricular rate is irregular in AF?
Atrial fibrillation (AF) may sound like a simple clinical arrhythmia until we ask this delicate question. The traditional and fairly accepted answer is that, AV node w...

Knowledge check in Brugada syndrome : A rapid fire session
A 5-minute session: Answers are my own. Please cross-check.
1. Is Brugada syndrome clinical or ECG diagnosis?
Always clinical. Never get confused on this.
2. Spontaneous type 1 vs Induced Type 1 (from type 2) which carries more risk?
Both are risky since they are close cousins. But, spontaneous type 1 is the dreaded devil.
3. Is Brugada primarily a defect of myocardial depolarization or repolarisation?
Not clear. Often in both. In fact a mismatch between them. (Don’t ask how Na+ Channel defect affects repolarisation !)
4. Is Brugada VT is monomorphic, polymorphic?
Both. What determines m...

An Interaction in IMCU
How is Mr. K, who was shifted from ward 102 ?
Yes sir, It was acute decompensated LV failure, Patient was in impending pulmonary edema. In fact, he developed. He is fine now,
How did he come around? He was too sick I thought.
“Just pushed 60 mg Frusemide IV, luckily he also had good BP, so with an infusion of NTG, titrated Carvedilol a little bit, he came out nicely. I guess it is Ischemic DCM”.
“Good, You have done a nice job”
