ACS2 Flashcards
Angioplasty superior ti thrombolytics bs
- Better survival and mortality
- Less bleeding
- complications of MI decreased
- Less arrhythmia,less CHF, fewer ruptures of septum, free wall( tamponade)and papillary muscles(valve rupture)
90min of arriving in ED with chest pain
PCI
“Door to balloon time”
Under 90 minutes
Complications of PCI
- Rupture of coronary artery
- Restenosis
- Hematoma at entry site into artery
Most important in decreasing the risk of restenosis of CA after PCI?
Placement of drug-eluting stent( paclitaxel, sirolimus)
PCI=
Angioplasty
For DVT and PE ( VENOUS thrombosis) not Arteries
Warfarin
Restenosis within 6 months of PCI without stent
30-40%
Restenosis within 6 months of PCI with bare metal stent
15-30 %
Restenosis within 6 months of PCI with drug-eluting stent
10%
If contraidications to thrombolitics
Transfer to facility performing PCI
Abs. Contraindications to Thrombolitics
- Major bleeding( bowel= melena, brain)
- Recent surgery (within last 2 weeks)
- Severe HTN> 180/110
- Nonhemorrhagic stroke within last 6 months
NOT an absolute contraindication to the use of thrombolitics
Heme-positive brown stool
Best initial therapy, everyone
Aspirin
All MI undergoing angioplasty and stenting
Clopidigrel
Everyone, effect not dependent on time during admission
Beta blockers
Everyone, benefit best with ejection fraction< 40 %
ACEi/ARBs
Everyone, best with LDL > 100 mg/dl
Statins
No clear mortality benefit
Oxygen, nitrates
After thrombolitics/ PCI to prevent restenosis, initial Tx with NSTEMI and unstable angina
Heparin
If can’t use BB, cocaine-induced pain, Prinzmetal angina
Calcium-channel blockers
In the process if forming clot in CAD= ST depression= unstable angina, after aspirin
Low molecular-weight heparin
Abciximab, Tirofiban,Eptifibitide
Glycoprotein IIb/IIIa inhibitors
- for pt who undergo angioplasty and stenting
* not beneficial in acute ST elevation infarctions
Glycoprotein IIb/IIIa inhibitors
New LBBB or ST elevation within 12 hours
Thrombolitics
Glpr IIb/ IIIa inhibitors
Inhibits platelet aggregation
Reduction in mortality with ST depression, particularly in pts whose troponin or CK-MB rise and then develop MI requiring PCI with stenting
Glycoprotein IIb/IIIa inhibitors
