Ischaemic cardiovascular disease Flashcards
untreated vs treated mortality of cardiogenic shock
90% to 50%
where does cardiogenic shock often occur
acute MI, often with occluded LAD
what are the symptoms of angina
visceral chest pain - may radiate to arm, back, neck, jaw
provoked by exertion and will do away stopping exertion
may be after meals
in diagnosing angina what should also be considered alongside symptoms?
risk factors
if its the symptoms of angina, but not angina what could it be?
reflux peptic ulcer oesophageal spasm nerve or muscular injury pericarditis pleuritic pain
if someone has severe pain that doesnt go away with >10mg morphine what could it be
acute MI
tearing excruciating pain that quickly alleviates could be
aortic dissection
where is a false positive in risk factors common
high risk individuals who are younger
where is a false negative in risk factors common
low risk individuals who are older
who isnt likely to have angina
younger people
pros and cons of angiography
Pro - gold standard, risk stratified, anatomical data
Con - radiation, invasive, contrast may cause renal dysfunction, dissection, stroke
pros and cons of CT angiography
Pro - non invasive, risk stratified, anatomical data
Con - expensive, radiation, angiography more precise
pros and cons of exercise testing
Pro - cheap, risk stratified, reproducible
Con - in older age can be poorly accurate in diagnosis
pros and cons of perfusion scanning
Pro - non invasive, more precise than ETT, risk stratified
Con - radiation, false positives/negatives
in CABG where is the great saphenous vein harvested and where does it go
leg
right coronary artery
