CAD highlights

Question 1

Which coronary artery supplies most of right atria and ventricle?

Answer 1

RCA

Question 2

List 4 branches of the RCA and what they supply

Answer 2

1) SA nodal artery br. – SA node
2) Right marginal br. – RV, apex
3) AV nodal br. – AV node
4) Posterior IV br.: Posterior 1/3 of septum & adjacent ventricles, anastomoses with circumflex br. of LCA

Question 3

What supplies posterior 1/3 of septum & adjacent ventricles and anastomoses with circumflex br. of LCA?

Answer 3

Posterior IV br. of coronary artery

Question 4

List 3 ways to modify risk factors for CAD

Answer 4

Lifestyle:
1) Exercise
2) Weight loss
3) Smoking cessation

Question 5

What should you Rx for stable CAD?

Answer 5

1) Antiplatelets
2) Antianginals
3) Statin (usually high intensity)

Question 6

List 2 antiplatelet that can be used for stable CAD

Answer 6

1) ASA
2) Clopidogrel (Plavix)

Question 7

List 2 antianginal Txs for CAD

Answer 7

1) SL Nitroglycerin (short term relief)
2) B-blockers (long term relief)

Question 8

What is the short acting drug of choice for immediate relief from anginal symptoms?

Answer 8

SL NTG 0.4 mg PRN angina

Question 9

What is the MOA of Ranolazine (antianginal)

Answer 9

Inhibits sodium & calcium current decreasing ventricular diastolic tension and myocardial oxygen demand

Question 10

Why is Ranolazine an alternative to BB or CCB in patients with anginal and hypotension or bradycardia?

Answer 10

No effect on BP or HR

Question 11

What is a well-established MAJOR risk factor for CVD?

Answer 11

Hypertension control

Question 12

Aspirin:
1) Should you use it as secondary prevention for CAD?
2) What abt as primary prevention? (meaning they already have CAD)

Answer 12

1) Secondary prevention: yes
2) Primary prevention: depends, but should do if calculated 10-year risk >10%
