Question 1

TIMI Risk Calculation

Answer 1

• predicts risk of death or MI in the next 14 days

- risk varies from 5-41%

Question 2

Answer 2

1. diminish coagulability
2. relieve pain
3. decrease workload of the heart

Question 3

What meds are used to diminish coagulability in UA/NSTEMI pts?

Answer 3

• anti platelets: ASA, P2Y12, IIbIIIa inhibitors

- anti coagulants: heparinoids, bivalrudin

Question 10

Prasugrel should be used in what types of pts?

Answer 10

-in high risk MI patients (DM or hx of MI) getting PCI

Question 11

When should IIaIIIb inhibitors be used before PCI?

Answer 11

• DM or STEMI or elevated troponins and low bleed risk

- recurrent pain on ASA, P2Y12, and heparin

Answer 12

-0.4 mg SL q5 minutes for 3 doses

Question 13

When is IV nitro contraindicated?

Answer 13

• hypotension (SBP < 100)
• tachycardia > 100 bpm

Answer 15

• hypotension SBP < 100

- tachycardia > 100 bpm

Question 16

Answer 16

First 24 hours for all patients who do not have:

Answer 19

• hypotension (SBP < 100)
• BL renal artery stenosis
• hx angioedema
• 2 or 3 trimester pregnancy

Question 20

What are the goals of therapy for treating STEMI?

Answer 20

• relieve pain
• re-perfuse
• diminish coagulability

Question 21

When are lytics used?

Answer 21

• given if the 90 minute PCI window is not met

- most effective within 12 hours of symptom onset

Question 22

Absolute CI of Lytics

Answer 22

- ischemic (thrombotic) stroke within 3 months

Question 23

Relative CI of Lytics

Answer 23

• uncontrolled HTN
• current anticoagulant use (warfarin)
• pregnancy
• surgery <3 weeks

Question 24
