Myocardial infarction
1. A hormone of the prostacyclin type released from blood platelets, which induces platelet aggregation and arterial constriction.

Adenosine diphosphate
Serotonin
Thromboxane
Cyclo-oxygenase
Thrombin

2. Lactate dehydrogenase rises ___ hours after an MI and takes ___ hours to peak

1-4, 6-7
3-12, 10-24
3-12, 12-48
8-12, 24-48
2-6, 12

3. An enzyme responsible for formation of important biological mediators called prostanoids. Pharmacological inhibition can provide relief from the symptoms of inflammation and pain.

Thromboxane
Adenosine diphosphate
Serotonin
Cyclo-oxygenase
Thrombin

4. A potent oral antiplatelet agent often used in the treatment of coronary artery disease, peripheral vascular disease, and cerebrovascular disease.

Ramipril
Rosuvastatin
Aspirin
Clopidogrel
Propranolol

5. Widely distributed in the tissues, particularly in the blood platelets, intestinal wall, and central nervous system. Thought to play a role in inflammation similar to that of histamine and it is involved in the genesis of a migrainous headache.

Serotonin
Adenosine diphosphate
Thromboxane
Cyclo-oxygenase
Thrombin

6. CTnT rises ___ hours after an MI and takes ___ hours to peak

1-4, 6-7
3-12, 12-48
2-6, 12
8-12, 24-48
3-12, 10-24

7. A complex of three proteins that is integral to muscle contraction in skeletal and cardiac muscle, but not smooth muscle.

Myoglobin
Troponin
Lactic Dehydrogenase
C-reactive protein
Creatinine Kinase

8. Myoglobin rises ___ hours after an MI and takes ___ hours to peak

2-6, 12
1-4, 6-7
3-12, 12-48
8-12, 24-48
3-12, 10-24

9. Acts as an enzyme, converting the soluble protein fibrinogen to the insoluble protein fibrin in the final stage of blood coagulation. Not normally present in blood plasma.

Serotonin
Thromboxane
Thrombin
Cyclo-oxygenase
Adenosine diphosphate

10. A compound containing adenine, ribose, and two phosphate groups. Occurs in cells and is involved in processes requiring the transfer of energy.

Thromboxane
Thrombin
Adenosine diphosphate
Cyclo-oxygenase
Serotonin

11. Aspirin may be given in pre-hospital MI treatment. How much?

300 mg
30 mg
3 mg
3g
30ng

12. This isomer originates from brain and thyroid, skeletal muscle, and cardiac muscle. Any damage to these tissues causes an increase of the isomer in the serum, which can be used in diagnosis, particularly of myocardial infarction.

Myoglobin
Lactic Dehydrogenase
Troponin
Creatinine Kinase
C-reactive protein

13. A combination of angina, non-ST elevation myocardial infarction, and ST elevation myocardial infarction.

cardiac insufficiency
ischaemic artery disease
coronary artery disease
acute coronary syndrome
heart failure

14. CTnl rises ___ hours after an MI and takes ___ hours to peak

3-12, 12-48
2-6, 12
3-12, 10-24
