Flashcards in Myocardial Infarction Deck (10)
What is a STEMI?
A myocardial infarction that illustrates ST elevation on an ECG
What is a NSTEMI?
A myocardial infarction that doesn't illustrate ST elevation on an ECG
What is an unstable angina?
Where there is partial occlusion of a coronary artery that leads to ischaemia that causes pain at rest
What causes a STEMI?
There is a rupture of a coronary plaque which leads to an occlusive thrombus (completely blocking a blood vessel) leading to large amount of ischaemia
What is ST elevation in myocardial infarction indicative of?
This indicates ischaemia
What are Q waves in myocardial infarction indicative of?
Infarction, irreversible myocardial death.
What are the clinical signs and symptoms of acute myocardial infarction?
As a result of ischaemic myocardial injury: chest pain (angina), a 4th heart sound, low grade fever, leukocytosis and raised CRP and troponin I and T release
As a result of autonomic disturbance: tachycardia, sweating and vomiting
What drugs may be given post-MI as a form of secondary prevention?
• Ticagrelor (platelet aggregation inhibitor)
• ACE inhibitors
What are the treatments for NSTEMI?
Anti-coagulants, vasodilators and antiplatelet drugs.
