Q

When do you take cardiac enzymes?

A

In the ED, after doing an EKG, for acute chest pain.

Never do cardiac enzymes in an office/ambulatory setting or when the chest pain is chronic or stable.

Q

What is the most accurate test for pneumothorax?

A

Chest x-ray

16
Q

Fever with chest pain suggests which 2 diseases as possible causes?

A

Fever suggests PE or pneumonia as the cause of chest pain.

17
Q

What symptom in the setting of chest pain has the worst prognosis?

A

Shortness of breath

18
Q

When do you do stress testing?

A

When the etiology of chest pain is unclear is uncertain and the EKG is not diagnostic. It requires that you can read the EKG and that the pt can exercise.

19
Q

When is stress testing C/I?

A

If the pt is currently having chest pain.

20
Q

What are some of the causes of EKG abnormalities that make the EKG unreadable?

A

Reasons for baseline EKG abnormalities include:

  • LBBB
  • LVH
  • Pacemaker use
  • Digoxin
21
Q

What are 2 ways to detect ischemia if you cannot read an EKG?

A
  • Nuclear isotope uptake using thallium or sestamibi; decreased uptake indicates dead or hypoperfused myocardium
  • Echocardiographic detection of wall motion abnormalities; decreased wall motion during contraction indicates abnormal myocardium
22
Q

How can you detect ischemia if the pt cannot exercise?

A

Alternate methods of increasing myocardial oxygen consumption are:

  • Persantine (dipyridamole) or adenosine in combination with the use of nuclear isotopes such as thallium or sestamibi
  • Dobutamine in combination with the use of echocardiography; dobutamine will increase myocardial oxygen consumption and provoke ischemia detected as wall motion abnormalities on an echocardiogram
23
Q

What is the most accurate method of detecting CAD?

A

Angiography is used to detect the anatomical location of CAD. It is used to detect the presence of narrowing that is best managed with surgery, angioplasty, or other methods of revascularization.

24
Q

What percent stenosis must a vessel be before clinically significant?

A

Stenosis of less than 50% of the diameter is insignificant. Surgically correctable disease generally begins with at least 70% stenosis.

25
Q

Which medications (3) will lower mortality in chronic angina?

A
  • Aspirin
  • B-blockers
  • Nitroglycerin
26
Q

What is a Holter monitor used for?

A

Holter monitoring mainly detects rhythm disorders (eg atrial fib or flutter, ectopy such as premature beats, or ventricular tachycardia).

Holter monitor does not detect ischemia and is not accurate for evaluating the ST segment.

27
Q

How is nitroglycerin delivered in chronic angina? How is it delivered in acute coronary syndromes?

A

NG can be delivered orally or by transdermal patch in chronic angina.

For acute coronary syndromes, NG is delivered in sublingual, paste, and IV form.

28
Q

When is clopidogrel used?

A
  • Aspirin intolerance such as allergy

- Recent angioplasty with stenting

29
Q

For what 2 conditions are ACEI’s/ARB’s the DOC?

A
  • Low EF / systolic dysfunction

- Regurgitant valvular disease

30
Q

For what 4 diseases, equivalent to CAD, should the goal of LDL be below 100, and for which statins should be used to bring down the LDL if above 100.

A
  • Peripheral artery disease (PAD)
  • Carotid disease (not stroke)
  • Aortic disease (the artery, not valve)
  • Diabetes mellitus
31
Q

Wide splitting of S2 with a loud P2 or tricuspid and pulmonary valve insufficiency; dyspnea; syncope

A

Pulmonary HTN
