how does a myocardial infarction happen?
- blood clot
- stops blood flowing to the heat muscle
- depriving heart muscle of o2
how does a clot form?
-if there are plaques
where are plaques formed?
-lining of the arteries
what is the name of the cardiac enzyme that diagnoses myocardial infarction?
-troponin
why do troponin levels increase?
- increase when cells are damaged
- due to oxygen deprivation
how long is the troponin detectable in the serum?
-6 hours after heart attack
how long does troponin remain in the serum?
14 Hours
when does troponin peak?
12-24 hours
what are the 3 names of the plaques causing a heart attack?
- unstable plaque
- stable plaque
- osclerotic plaque
name the 3 different anti platelets
- Ticagrelor
- cangrelor
- prasugrel
What are the 3 main points for unstable angina?
- symptoms of MI
- no rise in troponin
- no change in ECG - therefore stable angina
what is stable angina like?
- chest pain and discomfort
- narrowing of coronary arteries
what are anti-coagulant drugs?
-drugs that prevent blood clotting
what are antithrombotic drugs?
-prevents formation of thrombus
what are thrombolytic drugs?
-drugs that dissolve blood clots
