FDA Gives Clearance for Drug to Treat Thrombotic Diseases

DAIC

In the natural, physiological mechanism of clot lysis, while tissue plasminogen activator (tPA) initiates clot lysis, prourokinase completes the dissolution of the fibrin clot. This IND clearance is a significant step toward expanding access to our low-dose fibrinolytic treatment for broader patient populations globally."

Cardiac psychology and ectopic heartbeats

Dr. Sanjay Gupta

This can then become a vicious cycle – if we feel anxious, frightened, or stressed in response to an ectopic beat this can lead to physiological symptoms associated with the stress response including changes to our heart rate. For example, avoiding cardiovascular exercise or activities triggering breathlessness.

What do heart tests tell us?

Dr. Sanjay Gupta

So cardiomyopathies, valve problems, myocarditis and previous heart attacks all cause a problem with the pumping function of the heart. It is also unique because it works using the Doppler effect, you can get not only an anatomical evaluation of the heart but also physiological assessment.
