acute cards pt 1 Flashcards
Prinzmetal’s angina
coronary artery vasospasm (not precipitated by atherosclerosis)
treatment w calcium channel blocker
type 1 MI diagnosis
rise/fall of troponin >99th % URL plus one of the following:
- symptoms of acute myocardial ischemia
- EKG changes indicative of new ischemia (new ST/T wave changes or new LBBB)
- new pathologic Q waves
- imaging evidence of new loss of viable myocardium or new regional wall motion abnormality
-ID of coronary thrombus on angiogram
populations that commonly have atypical presentations of MI
women
diabetics
heart failure diagnosis
ESRD
geriatrics
troponin
preferred cardiac biomarker for acute MI
troponin I rises faster than troponin T & is specific to cardiac necrosis
should be obtained in all patients with CP concerning for MI
trend q6 to peak
ACS mgmt
emergency - morphine .1 mg/kg IV (2-4 mg); oxygen, Nitro 0.4 SL; aspirin 162-325 mg PO
B blocker PO within 24 hr of admit
antithrombotic therapy - aspirin, heparin gtt/enoxaparin, clopidogrel
consider nitro gtt
PCI within 90 mins!!!!!
fibrinolytic therapy within 3 hr of symptom onset (if no PCI availability)
CI to fibrinolytic therapy
previous hemorrhagic CVA, other CVA or event within last ear, active internal bleeding, suspected aortic dissection
Post STEMI meds
beta blocker - everyone unless cardiogenic shock, decreased output states, hypotension, or severe asthma
statin - everyone
ACE/ARB - if anterior infarct or LV dysfunction, caution in renal disease
SL nitro before activity
dual anti platelet therapy
dual anti platelet therapy
post STEMI 12 months for high risk & low bleeding risk, <12 mos for high bleeding risk/low ischemic risk
aspirin (81-325 mg PO QD) - reduce morbidity/mortality - indifinite tx
AND
clopidogrel (plavix) OR prasugrel (effient)
-loading dose & maintenance therapy
Dressler syndrome
fever, malaise, fatigue, arthralgias, CP occurring ~2 weeks following PCI or cardiac event
secondary pericarditis w/wo effusion
causes of acute HF
acute valvular (mitral or aortic regurgitation)
MI
myocarditis
arrhythmia
drugs (cocaine, CCB, BB OD)
sepsis
RHF vs LHF
??????
left - s/s of pulm edema (crackles, resp distress, A fib, S3, murmur, pulm congestion on CXR
right - FVE (increased CVP, JVD, edema, ascites, S3/S4, hepato/splenomegaly)
cardinal exam findings of HF
parasternal lift
displaced PMI
diminished S1
S3/S4
CI to LVAD
RV ventricle failure ( cannot support LV flow)
