3D Printed Heart Muscle Beats
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a technique that allows them to 3D print a heart ventricle, that can then go on to beat rhythmically. The technology could allow researchers to creat...

63 year old with " good story for ACS " but negative troponins.....
This was texted to me from a former resident, while working at a small rural hospital, with the statement:" I can ’t convince myself of anything here, but he’s a 63-year-old guy with prior stents and a good story for ACS. " (Chest pain or discomfort)What do you think?Here was my response:" Suspicious for inferior posterior OMI. Get serial ECGs "He then sent a previous from 4 years prior:" This is totally normal, which confirms that the first EKG does indeed represent OMI "Then the patient ' s chest pain resolved and he recorded another:The ST depression in aVL is gone and the T-waves are less hyperacu...

Our OMI Toolbox Application is out now !
We are happy to announce that our " OMI Toolbox " application has just released and ready for your use. As myocardial infarction (MI) and many other diagnoses (for example left ventricular hypertrophy, prior MI etc.) can cause ST-segment elevation (STE) on electrocardiogram (ECG), the distinction between them may be hard and complicated. Furthermore, some ECGs may not meet the STEMI criteria but may still be diagnostic for acute coronary occlusion (ACO). For this purpose, only one set of diagnostic or differentiating criteria (STEMI criteria) is not enough, therefore a bunch of different tools are needed to make a&nbs...

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...

Important blood tests in relation to the heart – Cardiology Basics
Important blood tests in relation to the heart – Cardiology Basics
Here are some important blood tests in relation to the heart. Normal ranges of some of these tests may vary between labs.
Cholesterol is a type of fat found in the blood and has a role in the development of atherosclerosis in the coronary arteries as well as other arteries. Desirable value of total cholesterol in blood is less than 200 milligrams per decilitre.
Triglycerides is another type of fat found in the blood. Desirable value is less than 150 milligrams per decilitre. Very high levels of triglycerides carry a risk of pancreatitis. Calorie restr...

5 Scenarios Of How Your Health Data Can Be (Or Was Already) Stolen
I really don’t want to sound like Aunt Karen, suspecting a culprit hiding behind every bush, but chances are your health data was or will be stolen. This is a strong statement and might sound paranoid. But, as the old joke goes: being paranoid doesn’t mean someone is not after you.
Here we will introduce five general scenarios of how unknown third-party actors can access your health data without your knowledge (and consent). We introduce these to paint a clearer picture of how medical data can change hands and help you prepare to avoid it – as much as possible.

Chest pain, shortness of breath, T wave inversion, and rising troponin in a young healthy runner.
In this study, 40 presumably healthy male marathon runners had their cardiac troponin and other findings measured before and after running a marathon. 39 pts (97.5%) had baseline cTnT values below the reference limit (less than 14 ng/L). 38 pts (95%) of participants had post-marathon cTnT concentration rise above this reference limit. The median post-marathon cTnT was 41 ng/L, and the 95th percentile concentration was 90 ng/L. None reported " cardiac symptoms " after the race.See this single post for many examples of BTWI:Understanding this pathognomonic ECG would have greatly benefitted the patient.More cases involving BT...

Quiz post - which of these, if any, are OMI? What is the South African Flag Sign? Will you activate the cath lab? Can you tell the difference on ECG?
Written by Pendell Meyers, additions and edits by Grauer, Smith, McLarenBelow we have 5 cases of adults (ranging from 40-70 years old) who all presented to the ED with acute nontraumatic chest pain that sounded at least somewhat like potential ACS to the provider. You should look at each ECG and decide if it is OMI, not OMI, or something else.Our goal in this post is to compare and contrast OMIs with false positives that mimic them. In this post we will examine the anterolateral distribution that has been described as the " South African Flag Sign. " (SAFS)It is very hard to describe why an ECG expert can easily...

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...

P2-CHA2DS2-VASc Score
P2-CHA2DS2-VASc score adds additional two points to the CHA2DS2-VASc score for an abnormal P wave axis to predict risk of stroke in atrial fibrillation (AF) [1]. The seminal study was an attempt to identify utility of P wave indices in sinus rhythm to predict the risk of stroke over and above the existing CHA2DS2-VASc score. P wave indices evaluated were prolonged P wave duration, abnormal P wave axis, advanced interatrial block and abnormal P wave terminal force in lead V1. They found that abnormal P wave axis which is an ECG correlate of left atrial abnormality improves the prediction of ischemic stroke. They concluded ...
