metoprolol and oxygen are also given in acute coronary syndromes
Unstable angina is actually no more in ACS. Sir said in latest videos.
And serial rise in cardiac biomarkers is needed for diagnosis of Stemi and nstemi both.
Unstable angina- because cardiac biomarkers are normal .
If cardiac biomarkers would have been raised, then the diagnosis would have been NonSTEMI
Sir metoprolol also increases o2 supply by decreasing force of contraction and aspirin also help to increase the blood flow as we know this is very old patient so chances of mild atherosclerotic plaque may be there.
A is for STEMI
NSTEMI - antiplatelets and anticoagulant is the mainstay
Digoxin is AV node blocker and also an antiarrhythmic drug.
It can itself cause arrhythmia, and nowadays hardly used in heart failure. why would we give that in a case of unstable angina without any sufficient history.
