Flashcards in cardiac diagnostics Deck (30):
1

CAD

2

  • indirectly measures cardiac electrical events
  • can be subjective
  • most helpful in acute setting

3

creatine kinase 

  • isoenzyme distributed in anumber of tissues
  • not cardiac specific 
  • used to detect 

4

CK-MB

  • primary source is myocardium

5

troponin

6

differentiate between Troponin T and I

  • T: larger
  • I: smaller 

7

telemetry

8

exercise ECG stress test

9

Nuclear medicine imaging

10

common radioactive element used in nuclear medicine imaging

11

what test is commonly preformed for pre-op or with prior non-diagnostic ECG stress test?

stress echocardiogram 

12

stress echocardiogram

13

US directed at heart to create images of cardiac anatomy

14

indications for transthoracic echo 

15

small US probe placed on a endoscope device down esophagus behind heart

16

transesophageal echo can detect what conditions

17

what is the gold standard for diagnosing CAD

18

cardiac catheterization/angiogram

19

holter monitor

20

event "loop" recorder

21

list risk factors for CAD

  • age
  • gender
  • HTN
  • hyperlipidemia
  • DM
  • tobacco use
  • family history 

22

onset of CK, CK-MB, and troponin?

3-12 hrs

23

duration of CK, CK-MB

24

duration of elevated troponin

less than or equal to 10 days

25

name the three stress tests

  • exercise ECG stress test
  • Nuclear medicine imaging
  • stress echocardiogram 

26

disadvantages of exercise ECG stress test

  • required capable patient
  • does not localize ischemia
  • does not evaluate LV function

27

indications of cardiac catherization/angiogram 

  1. known, suspected CAD
    1. unstable angina
    2. h/o MI with ECG changes
    3. post resuscitation from cardiac arrest
  2. atypical chest pain
    1. when non-invasive stress test reveals high risk of CAD
  3. before valve surgery in patient with chest pain or ECG changes 

28

percutaneous coronary intervention

balloon angioplasty

A image thumb
29

implantable loop recorder

  • subcutaneous monitoring device
  • device automatically activated according to programmed criteria
  • useful in patients with infrequent symptoms 

30

major applications of CT use in heart

  • detection aortic dissection
  • detection of coronary artery calcium deposition as an indicator for atherosclerosis
