| AAA Screening | |
| Aspirin for prevention of CVD | |
| Acute coronary Syndrome: Etiologies | 1. 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) |
| Troponin | 1. best biomarker for ACS 2. 3-6 hours after infarction 3. stays elevated for 7-14 days 4. not elevated in unstable angina |
| Myoglobin | 1. earliest biomarker - 2 hours -peaks at 8 hours 2. sensitive, not specific - skeletal muscle injury |
| CK-MB | 1. 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. |
| Acute Coronary Syndrome: treatment | 1. 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 |
| UA/NSTEMI treatment: When to do invasive intervention | 1. hemodynamic instability 2. sustained V. tach 3. PCI within 6 months 4. prior CABG 5. high risk score 6 LVEF < 40% |
| ACS: STEMI ECG findings | see Evernote |
