1

What does a 12 Lead ECG show you?

A 360 degree view of the heart using 12 viewpoints

2

What are the 2 forms of troponin?

Trop I (elevated for 2 weeks), Trop T (shows small amounts of damage)

3

What is MONA?

Morphine, Nitroglycerin, Oxygen, Aspirin (160-325 mg)

4

Why give morphiene in MI?

Reduce pain/anxiety. Need to be careful with hypotension, hypovalaemia, resp depression

5

Why give Nitro-glycerin in an MI?

Dilates coronary vessels, reduce systemic vascular resistance and preload (careful with hypotension)

6

Why give oxygen in an MI?

70% of ACS pts demonstrate hypoxemia, may limit ischaemic myocardial damage

7

Why give aspirin during an MI? and how much?

Irreversible inhibition of platelet aggregation

8

Additional nursing care post MI?

24 hr bed rest, light diet, continuous assessment/obs, anti-arrhythmic, analgesics, anti-coagulants, patient education (avoid strenuous activity), rehab and continuing education/support

9

What do inotropes do?

Alter the stretch of cardiac and other smooth muscle fibres
A1 + A2 -> vasoconstriction, B1 +B2 _> cause vasodilation and increased HR/contractibility

10

Secondary prevention of MI (behavioural interventions)

Pt education, 30-60 mins Physical activity with risk assessment, stop smoking, diet: fibre, omega 3

11

Meds used in ACS

Antiplatelet agent (aspirin/clopidorgrel), Lipid lowering agent (statin), Antihypertensive agent (Beta blocker, ACE-1, Aldactone

12
