ACS - medsurg 2 Flashcards
what are the 2 conditions that follow under acute coronary syndrome (ACS)
unstable angina & acute MI
when comparing angina pain to MI pain, characteristics of MI would include
-w/o a cause & usually in the early morning d/t cortisol surge
-relieved only by opioids
->20mins
-Sx: diaphoresis, dyspnea, anxiety, dysrhythmias
if someone “drops dead” bc of a heart attack, what was the cause
dysrhythmia
during an MI, how long can cells stand ischemia before cell death occurs
20 minutes
during an MI, how long does it take for the entire thickness of heart muscle to necrose
4-6 hrs
what layer of the heart is affected first during an MI
subendocardium
MI’s are described based on
location of damage (anterior, inferior, lateral, septal or posterior)
what does MI pain feel like
severe, immobilizing chest pain not relieved by rest, position change or nitrates
what is the hallmark sign of a MI
non responsive to nitrates
how might a pt describe their sx during an MI
-persistent
-heaviness, pressure, tightness
-burning
-constriction, crushing
complications of MI
-dysrhythmias
-HF
-cardiogenic shock
-papillary muscle dysfunction
-pericarditis
complications of MI: dysrhythmias
get on tele immediately
-most common comp
-causes pre hospital death
complications of MI: HF
occurs because of reduced pumping action of the heart
complications of MI: cardiogenic shock
loss of BP d/t severe left ventricular failure
complications of MI: papillary muscle dysfunction
leads to new murmur noted
