| ==MI Complications==
| | #REDIRECT [[Myocardial infarction complications]] |
| | |
| ===LV Free Wall Rupture===
| |
| *5-14 days after MI, earlier in thrombolysis pts
| |
| *Leaking of fluid outside can cause tamponade
| |
| **Look for JVD, pulsus paradoxus, diminished sounds
| |
| *Emergent Echo if stable
| |
| *Give IVF and consult CV surgery for pericardiocentesis and thoractomy
| |
| | |
| ===LV Aneurysm===
| |
| *Usually chronic and can persis for >6 wks after MI
| |
| *Tends to occur with ant MI
| |
| *Emergent Echo if stable
| |
| *Treat cardiogenic shock, anticoagulate if mural thrombus
| |
| *Defibrillate ventricular arrythmias
| |
| | |
| ===Septum rupture===
| |
| *3-7 days after MI
| |
| *Blood fills RV
| |
| **Listen for holosystolic murmur
| |
| *Emergent Echo if stable
| |
| *Reduce afterload with vasodilators and consult CV surgery
| |
| *Consider IABP
| |
| | |
| ===Papillary muscle rupture===
| |
| *2-7 days after MI
| |
| *Listen for murmur at apex
| |
| *Emergent Echo if stable
| |
| *Reduce afterload with vasodilators and consult CV surgery
| |
| *Consider IABP
| |
| | |
| | |
| | |
| ==Complications Based on MI Location==
| |
| ===Anteroseptal MI Complications===
| |
| *Look at V2-V4,5
| |
| *CHF/Cardiogenic shock
| |
| **Large area of myocardium involved
| |
| *Bradycardia
| |
| **Bundles thru septum knocked out leading to wide complex
| |
| *Myocardial tissue rupture
| |
| *LV aneursym
| |
| | |
| ===Inferior MI Complications===
| |
| *Look at II, III, aVF
| |
| *Bradycardias and AV block
| |
| **Increased vagal tone
| |
| **Sinus Node supplied by RCA in 60% of patients
| |
| **AV node supplied by RCA in 90% of patients
| |
| *Papillary muscle rupture
| |
| **RCA supplies inferior septum
| |
| **MI + new murmur + CHF think valve injury
| |
| | |
| ===Right Ventricle MI Complications===
| |
| *Inf MI with ST elev III>II, ST elev V1>V2, ST dep V2
| |
| **Lead III and V1 looks most at R side of heart
| |
| *RV mostly supplied by RCA
| |
| *Hypotension most severe complication
| |
| **Volume load
| |
| **AVOID vasodilators, do not give SLNG
