Cards in this deck (9)
- 1AAA Screening
- 2Aspirin for prevention of CVD
- 3Acute coronary Syndrome: Etiologies1. most commonly occlusive thrombus on top of disrupted plaque (50% in only 50% narrowed)
2. spasm at plaque
3. spasm in normal artery
4. inflammation (Kawasaki)
5. cocaine-induced (treat with NTG and CCB) - 4Troponin1. best biomarker for ACS
2. 3-6 hours after infarction
3. stays elevated for 7-14 days
4. not elevated in unstable angina - 5Myoglobin1. earliest biomarker
- 2 hours
-peaks at 8 hours
2. sensitive, not specific
- skeletal muscle injury - 6CK-MB1. remains elevated 36-48 hours
2. early peak (12-18 hrs) is indicative of re-perfusion
3.because of early rise and fall, is better than troponin for reinfarction dx. - 7Acute Coronary Syndrome: treatment1. Fibrinolysis within 12 hours of onset
2. Glycoprotein IIb/IIIa inhibition
3. Percutaneous Coronary intervention (PCI) with stent
4. CABG (emergency) - when PCI not possible - 8UA/NSTEMI treatment: When to do invasive intervention1. hemodynamic instability
2. sustained V. tach
3. PCI within 6 months
4. prior CABG
5. high risk score
6 LVEF < 40% - 9ACS: STEMI ECG findingssee Evernote
