Learning targeted IAS puncture in 20 minutes
The main reason for all those jitters, we cardiologists, get every time we puncture the IAS is not due to a lack of expertise and experience perse. There are two more reasons. First and foremost, it is still largely a blind* procedure. (Even in this era, where drones with HD vision shoot one-meter targets from a 1000 KM range )  *TEE and ICE are there, but they rarely give enough confidence.  The second reason is more important and is rectifiable. It is the perception error in our anatomical cognition, that is fed to us from first-year medical school. We are made to believe (at least to people like me ) The right atrium...

Cardiology update: Should mRNA vaccine myocarditis be a contraindication to future COVID-19 vaccinations ?
BY ANISH KOKA Myopericarditis is a now a well reported complication associated with Sars-Cov-2 (COVID-19) vaccinations. This has been particularly common with the messenger RNA (mRNA) vaccines (BNT162b2 and mrna-1273), with a particular predilection for young males. Current guidance by the Australian government “technical advisory groups” as well as the Australian Cardiology Society suggest patients who have experienced myocarditis after an mRNA vaccine may consider a non-mRNA vaccine once “symptom free for at least 6 weeks”. A just published report of 2 cases from Australia that document myopericarditi...

HOST-EXAM trial
This study is definitely hypothesis generating and calls for a multi national, double blind comparison on a larger scale to get a better conclusion on long term antiplatelet monotherapy after PCI with DES.  AUGUSTUS trial A somewhat similar disadvantage for aspirin was suggested in the AUGUSTUS trial among patients with atrial fibrillation and recent ACS or PCI [2]. Adding apixaban to P2Y12 inhibitor resulted in lower bleeding compared with vitamin K antagonist and a lower rate of death or rehospitalization. Addition of aspirin resulted in greater bleeding without any difference in efficacy. 92.6% of the patients...

Can The Tablighi Jamaat ’s Conference be India’s Own Epidemiological Diamond Princess?
By SOMALARAM VENKATESH, MD “It has always been science versus fundamentalism, not science versus religion.” Abhijit Naskar, Biopsy of Religions: Neuroanalysis Towards Universal Tolerance On February 3, 2020, the luxury cruise ship Diamond Princess docked on Japanese shores and was promptly quarantined with 3711 people on board, because a passenger who had disembarked at Hong Kong two days earlier had tested positive for SARS-Cov-2,  or also known as  COVID-19. Passengers & crew members were either repatriated or hospitalized in Japan over the next 4 weeks. In total,, more than 700 of them were ...

The COVID Pandemic: WHO Dunnit?
By ANISH KOKA, MD COVID is here. A little strand of RNA that used to live in bats has a new host.  And that strand is clearly not the flu.  New York is overrun, with more than half of the nation’s new cases per day, and refrigerated 18-wheelers parked outside hospitals serve as makeshift morgues.  Detroit, New Orleans, Miami, and Philadelphia await an inevitable surge of their own with bated breath.  America’s health care workers are scrambling to hold the line against a deluge of sick patients arriving hourly at a rate that’s hard to fathom.  I pause here to attest to the heroic r...

Highly Sensitive Wearable Strain Sensor Uses Light for Detection
Stick-on strain sensors that can accurately measure the flexion of joints, big and small, have turned out hard to make. Piezoresistive devices tend to have a delayed response and are not stable in the long-run, while capacitive sensors are not very s...

Fight Aging! Newsletter, March 25th 2019
This study defines a new clinically relevant concept of T-cell senescence-mediated inflammatory responses in the pathophysiology of abnormal glucose homeostasis. We also found that T-cell senescence is associated with systemic inflammation and alters hepatic glucose homeostasis. The rational modulation of T-cell senescence would be a promising avenue for the treatment or prevention of diabetes.

The Heart of The Matter: Technology In The Future of Cardiology
Sound, rhythm, rate, structure, function – countless features of the heart are measured to keep it healthy for as long as possible. Recently, an army of digital health technologies joined the forces of traditional preventive tools in cardiology to counter stroke, heart attack, heart failure or any other cardiovascular risks. In the future, minuscule sensors, digital twins, and artificial intelligence could strengthen their ranks. Let’s see what the future of cardiology might look like! Fitness trackers, chatbots and A.I. against heart disease Let’s say 36-year-old Maria living in Sao Paulo in 2033 decides one d...
