A 45 year old male smoker presented with chest pain radiating to neck

A 45 year old male smoker presented with chest pain radiating to neck and left shoulder for last 7 days. Examination was significant for resting tachycardia and pericardial friction rub with clear lung fields. ECG showed sinus tachycardia, diffuse ST elevation in all leads except aVR, V1. Troponins were modestly elevated. CBC, ESR, ANA, TFTs, all were normal.

a)      What is the diagnosis (complete diagnosis)

b)      What is the cause of troponin elevation

c)      Would you consider colchicine? If yes then give reason

d)      What are echo Doppler findings of constrictive pericarditis

e)      What is Becks traid

Answers:

a.      Acute MyoPericarditis

b.      Myocardial Involvement

c.       Yes, it reduces risk of recurrence, COPE Trial

d.

2D findings:

Septal bounce
Ventricular interdependence
IVC Plethora

Doppler Findings:

Respiratory variation in mitral and tricuspid flows: In mitral valve inflow peak E velocity decreases by 33% or greater. In tricuspid valve inflow peak E velocity increases by 44% or greater and peak A velocity increases by 38% or greater.
Pulmonary systolic/diastolic (S/D) flow ratio is decreased
Respiratory variation in hepatic vein flow

e. Muffled heart sounds, Hypotension and raised JVP

Learn Echocardiography | Standard Protocol for Performing Comprehensive Echocardiogram | Explained with Images and Videos

If you are just starting to learn echocardiography, you will find that learning the full echo examination protocol will be immensely useful. The full protocol will provide a solid foundation for your career in echo. I personally found that once I could execute the standard protocol flawlessly, I was able to add and refine additional echo scanning skills while deepening my understanding of the purpose of each echo image. The echo protocol illustrated in this article is the same one we currently use for all our patients in the hospital and meets or exceeds the standards of American Society of Echocardiography (ASE) for an adult echocardiography examination. The protocol presented here is meant as a guideline and does not cover every aspect (such as off axis views) of an echo examination. Also other hospitals will probably have slight variations of this protocol depending on the lab's needs, which is normal. This article's main purpose is to provide a solid foundation for ...

𝘼𝙣𝙩𝙞𝙘𝙤𝙖𝙜𝙪𝙡𝙖𝙩𝙞𝙤𝙣 𝘼𝙛𝙩𝙚𝙧 𝙎𝙩𝙧𝙤𝙠𝙚 in Patient with AF and acute IS/TIA European Heart Association Guideline recommends: • 1 days after TIA • 3 days after mild stroke • 6 days after moderate stroke • 12 days after severe stroke Early anticoagulation can decrease a risk of recurrent stroke and embolic events but may increase a risk of secondary hemorrhagic transformation of brain infarcts. The 1-3-6-12-day rule is a known consensus with graded increase in delay of anticoagulation between 1 and 12 days after onset of ischemic stroke or transient ischemic attack(TIA), according to neurological severity based on European expert opinions. However, this rule might be somewhat later than currently used in a real-world practical setting.
