Post-MI complications Flashcards
what is the most common cause of death from MI
VF leading to cardiac arrest
which type of MI can cause bradyarrythmia afterwards
inferior MI
affects the AV node causing AV block
what artery supplied the AV node
90% of people its the right coronary artery (AV nodal branch)
when can pericarditis present post MI
in first 48 hours
2-6 weeks later - Dressler’s syndrome
how do you treat pericarditis
NSAIDs
which complication presents as persistent ST elevation and left ventricular failure post MI
left ventricular aneurysm
(wall of the left ventricle is weakened from the damage)
treat with anticoagulation as clots can form in aneurysm leading to stroke
how does left ventricular free wall rupture present post MI
1-2 weeks afterwards
acute heart failure secondary to cardiac tamponade
how do you treat left ventricular free wall rupture
urgent pericardiocentesis and thoracotomy
how does ventricular septal defect present post MI
rupture of ventricular septum
happens in the first week
acute heart failure associated with a pan-systolic murmur
diagnose with echo
how does acute mitral regurgitation present post MI
acute hypotension
pulmonary oedema
early-to mid systolic murmur heard
what causes mitral valve failure after an MI
chord tendinae or papillary muscle rupture
