-PE
-Pulmonary HTN -Pneumonia/pleuritis -Pneumothorax |
|
|
What is cardiac oxygen demand?
|
HRxContractilityxAfterload
|
|
|
Until what %stenosis of myocardial blood vessels will maximal bloodflow continue to be achieved?
|
70%
|
|
|
What happens once a vessel is obstructed 70% or more?
|
Ischemia at maximal vasodilation
|
|
|
What should be done in the setting of a new ST elevation or new LBBB?
|
Immediately activate revascularization services or consider thrombolysis if remote.
|
|
|
What drug should be used to reduce cardiac demand immediately after an MI?
|
Beta blockers - metoprolol IV - to reduce HR, contractility, and afterload.
|
|
|
When should metoprolol be used with caution?
|
Hypotension
|
|
|
What is a 2nd line to b-blockers after MI?
|
CCB's
|
|
|
How do Nitrates affect the heart oxygen supply/demand?
|
Demand: decrease preload thus contractility
Supply: decrease afterload by lowering blood pressure |
|
|
In what patients should nitrates be used cautiously? Why?
|
Patients with critical aortic stenosis - these are dependent on preload and you don't want to drop it too much.
|
|
