Cardiovascular dysfunctions Flashcards
Acute Coronary Syndrome
ACS UA NSTEMI STEMI MI
UA
Unstable Angina
- PCI usually not indicated
- Not candidates for thrombosis
NSTEMI
non ST segment elevation MI
ST depression
No thrombolytics
May require PCI
STEMI
ST elevation
**Need prompt reperfusion
Assess for thrombolysis PCI or CABG
- Give tPA?
MI
Sustained Ischemia
Rapid Dx and Management of ACS to reduce complications
O2 ASA NTG 12 lead EKG IV access Serum cardiac biomarkers repeat in 6-12 hrs CXR Hx/Risk assessment
UA and NSTEMI
Fibrinolytic therapy is not recommended (used to break up clots)
1. Assess Risk
Low: prob no PCI
Intermediate: 1 of the following: CP>20 min, T wave inversion, elevated biomarkers, >70yo = Possible PCI
High: Prompt PCI
2. Tx
Assess Risk: Low
No intermediate or high risk features but there is at least one of the following:
new onset of cp not prolonged
nml EKG during cp
nml cardiac biomarkers
Probably NO PCI
Assess Risk: Intermediate
1 of the following; Cp> 20 min T wave inversion Q qaves Elevated cardaic biomarkers Age>70
POSSIBLY PCI
Assess Risk: High
1 of the following: Angina Ischemia at rest CP> 20 min New ST depression recurrent angina CHF s/sx <40% EF SBP <100 HR>100 or less than 60 prior CABG >75 yo
PROMPT PCI
Tx of UA and NSTEMI
- O2, continuous ECG, monitor, IV
- ASA, NTG
- Beta blockers
- IV NTG, MS
- Heparin
- Clopidogrel (plavix), anti-platelets
STEMI
Requires reperfusion
STEMI assess
Assess R/F complications: Adv age, DM Prior MI, A Fib, AVB Mitral Valve dysfunction ST elevation despite reperfusion Anterior MI Incr HR Dec BP Renal insufficiency
STEMI TX
O2, monitor, IV ASA< NTG, MS Fibrinolytic or PCI B Blockers Heparin Plavix ACE-I/ARB MgSo4 Ca 2+ blocker
Possible complications of MI
Arrythmias Rupture: Papillary muscle, ventricular septal or cardiac Papillary muscle dysfunction Ventricular aneurysm Pericarditis HF Pulm Edema Cardiogenic Shock Recurrent ischemia
