1

What is the worst risk factor for ischemic heart disease?

Diabetes Mellitus

2

What is the worst risk factor for ischemic heart disease?

Diabetes Mellitus

3

What is the most common risk factor for ischemic heart disease?

Hypertension

4

A patient with coronary artery disease should have an LDL goal of:

5

The involvement of these vessels in CAD is associated with poor prognosis

Left main coronary artery (covers approx. 2/3 of heart)

** a 2 or 3 vessel CAD is worse prognosis

6

ECG in stable angina is....

usually normal

7

Q waves on ECG are consistent with

prior MI

8

How to calculate maximum heart rate

220-age

9

Stress test aims to achieve HR that is....

85% of the max heart rate

10

ECG stress test is considered to be positive (i.e. ischemia is detected) if....

ST segment depression is present

11

Stress test is generally considered positive if patient develops any of the following:

ST segment depression
Chest pain
Hypotension
Significant Arrhythmia

12

Stress echocardiography test evaluates presence of ischemia by detecting....

Wall motion abnormalities

13

How is stress myocardial perfusion imaging conducted?

Via IV administration of radioisotope (Thallium 201) during exercise

***No uptake of the radioisotope in a particular area indicates no blood flow to that area-->Ischemic

14

How do adenosine and dipyridamole function in stress tests?

They cause generalized coronary vasodilation and thus are helpful in perfusion studies. Diseased arteries are already maximally dilated thus receive relatively less blood flow when the entire coronary system is vasodilated.

Via IV administration of radioisotope (Thallium 201) during exercise

***No uptake of the radioisotope in a particular area indicates no blood flow to that area-->Ischemic

27

What pharmacologic agents can be used in a stress test in lieu of exercise?

Adenosine, Dipyridamole, Dobutamine

28

How do adenosine and dipyridamole function in stress tests?

They cause generalized coronary vasodilation and thus are helpful in perfusion studies. Diseased arteries are already maximally dilated thus receive relatively less blood flow when the entire coronary system is vasodilated.

29

Unstale Angina

Chronic angina with increased frequency, duration, or intensity

new onset angina that is severe or worsening

Angina at rest
No ST elevation, no increased cardiac enzymes

30

What is the most accurate method of determining a specific cardiac diagnosis?

Cardiac Catheterization
