Cardiology

Question 1

for patients with low risk, stable chest pain without known CAD, what two options are reaonable to proceed with for further evaluation?

Answer 1

CAC or exercise stress testing

Question 2

t/f USPSTF found that the harms of screening low risk patients who are asymptomatic with exercise stress testing outweigh benefits

Answer 2

true

Question 3

what calculator should be used to determine need for further testing in a patient with stable chest discomfort with known triggers?

Answer 3

CAD consortium 2 calculator

Question 4

what is the standard criterion for the diagnosis of exercise induced ischemia on stress EKG?

Answer 4

horizontal or downsloping ST segments

Question 5

t/f studies show an inverse relationship between METs achieved on exercise stress testing and mortality

Answer 5

true

Question 6

what are the two chemical forms of stress test?

Answer 6

dobutamine and Lexiscan

Question 7

what two modalities can be used to conduct myocardial perfusion scan?

Answer 7

CT or PET

Question 8

perfusion defects seen on myocardial perfusion imaging that are present with stress but not at rest indicate what?

Answer 8

ischemia

Question 9

on myocardial perfusion imaging, perfusion deficits that present with both rest and stress indicate what?

Answer 9

prior infarction

Question 10

what pathway can be used to risk stratify patients with acute chest pain?

Answer 10

HEART score

Question 11

in a patient with acute chest pain with high risk for ACS, what is generally the next step?

Answer 11

invasive coronary angiography

Question 12

patients with acute chest pain and intermediate risk of ACS without known history of CAD should undergo what?

Answer 12

further evaluation with GXT, MPI or CMR imaging

Question 13

in a patient with stable chest pain at intermediate or high risk without known CAD, in addition to stress echo, MPI, CMR, stress EKG, what other modality for testing may be appropriate?

Answer 13

CTCA

Question 14

a patient without known CAD but with HTN and HLD and 3 months of chest pain has a low CAD consortium 2 risk. what are the two next potential options for evaluation of possible CAD?

Answer 14

CAC score or GXT

Question 15

what is the cutoff for METs needed during stress testing to qualify for exercise stress testing?

Answer 15

at least 5 METS

Question 16

t/f conditions such as COPD, chronic renal insufficiency and inflammatory conditions cause increase in troponin levels

Answer 16

true
