Long COVID cardiac studies: More questions than answers.
BY ANISH KOKA
The NIH recently announced $1.2 billion dollars in funding for research on Long COVID. This is in part because of a faction of scientists that have mined electronic health record databases to find evidence that the long term impacts of COVID on a variety of different organ systems is significant.
I have some concerns when it comes to the cardiac complications discussed related to Long COVID.
One of Dr. Al-Aly’s long COVID papers illustrates the issues with using large datasets to differentiate signal from noise. The authors used the US Department of Veterans Affairs national healthcare datab...

Assessing Heart Function and Fluid Status with Cardiac Scales: Interview with John Lipman, CEO, and Corey Centen, Founder, Bodyport
Bodyport, a medtech company based in San Francisco, developed the Bodyport Cardiac Scale, a set of weighing scales that can non-invasively assess fluid status and heart function. The scales can detect these signals through the feet when a patient ste...

Fight Aging! Newsletter, June 20th 2022
This study showed a negative relationship between the gaps and the number of senescence cells. Moreover, we found a similar reduction in 30-month-old naturally and 7-month-old D-gal-induced aging rats. Given these consistent data from different eukaryotic organisms, it suggests that the Youth-DNA-GAP is a marker of phenotype-related aging degree

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.

It ’s not your heart that’s failing. It’s our medical jargon.
A little over two years ago, my elderly mother was admitted to the hospital. Almost 90, she’d been short of breath for days — uncomfortable, perspiring, unable to sleep properly. Blood tests, a chest X-ray, and an echocardiogram followed, whereupon her doctor pronounced:“You have congestive heart failure, Mrs. Les.” I arrived on the sceneRead more …It’s not your heart that’s failing.

A man in his 50s with acute chest pain and history of prior MI
Written by Pendell MeyersA man in his 50s with prior history of anterior MI with LAD stent presented with acute chest pain similar but more intense than his last MI. He presented around midnight with pain that had started around 9pm the night before. He had taken NTG at home with no improvement, and immediately received morphine on arrival at the ED for severe chest pain (a very bad idea if your accuracy for finding OMI on ECG is low, since ongoing pain will be your last chance to identify those with ongoing untreated OMI).Here is his triage ECG at 0012:What do you think? What is the differential of this ECG?There is sinus...

Missing ECG signs of OMI is associated with early death
Written by Sean Trostel MD, with edits by Smith and MeyersA man in his 80s with history of CAD, MI s/p PCI, HTN, HLD, Afib, and HFrEF, presented with sudden onset, aching, central chest pain radiating to the left arm and shortness of breath that began in the morning, 1 hour prior to arrival to the ED. This was his initial triage ECG, recorded one hour after onset of symptoms, and a baseline ECG below for comparison:What do you think?Baseline on file: This ECG was interpreted as sinus bradycardia with no acute ST or T wave changes compared to prior. Despite the very poor quality and wanderin...

Cardiac failure Info desk : Diuretics never save lives, while Dapagliflozin does it in style !
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”
“Don’t make me embarrassed sir. It is such a routine in our ER.
To make him curious, I asked “Which drug do you think that saved hi...

Basics of hemodynamic evaluation
Though invasive hemodynamic evaluation was pushed to the backstage with the development of Doppler echocardiography, it is again coming to centre stage with newer therapeutic options being available in pulmonary hypertension and heart failure. A basic knowledge of the principles of hemodynamic evaluation is essential to understand cardiac physiology.
Hemodynamic evaluation usually includes both right and left heart catheterization, though in some cases only one may be done. While writing a report of hemodynamic evaluation, it is customary to note the catheter course as it gives valuable complementary information. Catheter...

WTF Health: Early-Stage Med Device Startup Acorai is Turning Smart Phones into Heart Failure Monitoring Devices
By JESSICA DaMASSSA, WTF HEALTH
Acorai is an early-stage medical device startup working with Bayer to improve the way we manage the world’s 65 million patients living with heart failure by using their own smart phones. CEO Filip Peters shows the Acorai device, which is basically an extended smart phone case packed with four different kinds of sensor technologies that work together to measure the pressure inside a patient’s heart, by simply holding their phone against their chest. Of course, the real magic is the algorithm that turns these readings into early detection of a potential incident. How does this stack up ...

INTERMACS classification for advanced heart failure
INTERMACS classification for advanced heart failure was developed as a sub classification for advanced heart failure, typically for those in advanced NYHA (New York Heart Association) Functional Class III and IV. Interagency Registry for Mechanically Assisted Circulatory Support
(INTERMACS) developed this classification with seven clinical profiles and an arrhythmia modifier [1]. This was to allow optimal selection of patients for medical and pacing therapies, cardiac transplantation and mechanical circulatory support.
They found that 80% of current devices are being used in 2 profiles with the highest level of clinical...

Right Heart Catheters
Right heart catheterization was the initial type of cardiac catheterization introduced by Werner Forssmann in 1929, who did self-catheterization [1]. But later, with development of coronary interventions, it became less commonly done. Now there is a renewed interest as it is useful in the evaluation of pulmonary hypertension [2] and heart failure as well as in congenital heart diseases.
Though the catheter used by Forssmann was a ureteral catheter, dedicated right heart catheters came into use later. Cournand catheter is a right heart diagnostic catheter named after the Nobel laureate André Cournand, who shared the Nob...
