Ischemic cardiomyopathy: Why is it, still searching for a definition?
The term Ischemic cardiomyopathy(ICM) was originally coined by Dr. Burch from Tulane University, New Orleans, USA in 1970. For many decades there was skepticism regarding the existence of such entity. WHO classification over the years never included this term. ESC working group of 2008 (Elliott P, European Heart 29(2):270–276) decided not to include CAD as a cause for cardiomyopathy. Even the current MOGES system doesn’t invoke CAD as a cause for cardiomyopathy. But, I am sure, most of practicing cardiologists would agree, there is a need for such an entity.
Why there is much reluctance to diagnose Ische...

Digoxin in Heart failure: Foxglove blossoms again, please don ’ t crush it this time!
William Withering the British Botanist of 18th century now laid to rest in the St Barthomlew Churchyard ,Edgbaston is known for his astonishing isolation of the wonder moelcule Digoxin from Foxglove. (Of course, let us not forget original old lady Ms. Hutton from Shropshire who was treating epidemic dropsy with a concoction of herbal Tea ) He reported this in the seminal paper “An account of Foxglove’ in the year 1750 and subsequently became a fellow of Royal college of science.
(The story of Withering and Digoxin is extensively researched and written by Dr Dennis M, Krikler in a classic review article of 198...

DM cardiology course suffers from a 50% entry block … A NEET angioplasty done.
The most premier course in medicine, DM cardiology just got an entry makeover.
The qualifying mark was lowered to 20% from the current 50th percentile The reason is many private medical college seats went vacant after the Initial counselling in NEET superspeciality exams.
Becoming a cardiologist was a dream come true for those days for us. “You have to read the red covered 3rd edition Brunwald and all clinical chapters from Hurst for two full years” before even to think of writing DM entrance, my senior used to tell me in late 1980s.Yes, life may still be tough in post graduate entrance but, there is an exclus...

Fight Aging! Newsletter, August 12th 2019
We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined.
Mean nonfasting cholesterol concentration was 72...

Master health musings : Where did Alexander the Great, checked his LDL and Chenghis khan recorded his BP ?
A middle-aged man a Biotech engineer, who is just back from his annual health check, sitting in front of me with a deeply anguished face and said “Doctor my LDL is 130mg, and my diastolic BP is 90 mmHg and fasting sugar is 120 mg .I am very much worried about my future”
Wait , let me go through your file, I said ,
Isn’t a serious Issue doctor?
No, its not ,
But , doctor, I have read about ASCOT, SPRINT and HOPE-3 trials. I guess they tell us to keep the LDL, blood sugar and diastolic BP all these three parameters around 80. Isn’t doctor? He went on to add, that his old fashioned family physician ha...

Change and the Case for Being a Medical Conservative:
When my favorite podcaster, the economist Tyler Cowan, asked Dr. Ezekiel Emanuel what nonobvious advice he would give to medical students today, the answer surprised me.
The famous bioethicist said:
I do think that this is probably the most exciting time in American medicine in a century, since really about 1910, 1920. And it causes a lot of anxiety for people, so I want to be sympathetic to that….
…We would prefer no change. But I do think, if you can go with the change, this is a super exciting time when lots of things are changing, and you can have a real positive impact in shaping the future, pr...

Still Negative on Watchman
Many readers have contacted me to ask whether my negative viewson left atrial appendage occlusion with Watchman have changed since 2017.
The short answer is no. My views are even more negative today.
In 2016, I published an editorial on theHeart.org | Medscape Cardiology arguing that this procedure should stop. One of the rebuttals was that it was a blog post, not an academic editorial.
Months later, Andrew Foy, Gerald Naccarelli and I put the same argument into academic-speak and the influential journal Heart Rhythm published it.[1]
I have debated and presented this topic multiple times ...

Kardia Mobile – Smart phone based ECG
Kardia Mobile – Smart phone based ECG
Kardia Mobile (Alivecor, San Francisco, CA, USA) is a smart phone compatible device that allows recording of a single lead ECG [1]. Recently a third sensor has been added to allow 6 lead ECG.
MOBILE-AF trial (Mobile Phones in Cryptogenic Stroke Patients Bringing Single Lead ECGs to Detect Atrial Fibrillation) is evaluating the role of Kardia Mobile in detection of atrial fibrillation in patients with cryptogenic stroke [2]. It is an international multicenter trial of patients with cryptogenic stroke or transient ischemic attacks. Half of the patients will receive the self ECG re...

Tachycardia, fever to 105, and ischemic ST Elevation -- a Bridge too Far
Discussion of Figure-1: As per Dr. Smith — ECG #1 showed marked sinus tachycardia at ~140/minute — with diffuse ST segment elevation.I often find it difficult to determine the precise amount of ST elevation when the heart rate is very fast. For clarity — I ’ve added short horizontal RED lines in Figure-1 to show what I took as the “baseline” for assessing the amount of J-point ST elevation for the 2 ECGs in this figure.It may be especially difficult when there is marked tachycardia to identify the J-point that defines the number of millimeters of ST elevation. T...

“ Myocardial intelligence ” and ability to survive Ischemia !
One popular definition of Intelligence goes something like this “It’s a global capacity of a living organism to deal effectively with environment and live peacefully”
When myocytes are confronted with acute ischemia , they don’t always jitter . It expresses many behavioral pattern.The damage inflicted is variable as the molecular mechanism of ischemic tolerance appears to be a virtue ! This might make much revered time window of myocyte ischemia irrelevant .Each cell has got a unique capacity to survive or die . In chronic ischemia this myocyte intelligence and intention to survive is ...

Some thoughts about Origin , Genesis and Mechanism of palpitation !
Not every one feels the palpitation during tachycardia / Bradycardia /VPDs , Why ?
Palpitation is awareness of one’s own heart beat. It is a complex perception of sensation at cortical level (like dyspnea) . It can occur during physical and mental exertion.However , if it occurs without any physiological reasons , it becomes abnormal. It can mean an abnormally heart in terms of heart rate , rhythm or raise in stroke volume. The first rule of palpitation is both tachycardia and bradycardia can cause it. Tachycardic palpitation is due to valve motion and braducardic palpitation is due to both motion and increased...
