An underwriter's guide to cardiac diagnostic testing Flashcards
What are the three factors to be evaluated by testing?
- Ejection Fraction - how well the heart is functioning
- How much the heart is damaged
- Risk of sudden death
How do you determine which test to us?
- accuracy of the test
- cost of the procedure
- risks to the patient
What is a sensitive test?
Will give positive result of condition early on.
What is a specific test?
Only positive for one disease/condition.
What are blood test we can use for cardiac diagnostic?
Lipids
NT-proBNP
Troponins
CPK
AST
LDH
Which CPK is found mostly in the heart?
CPK-MB/CPK-2
Which changes in an EKG are worriesome for someone with known cardiovascular risk?
ST-Segment or T wave
EKG abnormalities are categorized into which five areas?
- heart rate
- heart rhythm
- axis or position of the heart
- cardiac hypertrophy
- myocardial infarction and/or ischemia
What are the echocardiogram report?
- Results of the M-mode exam
- 2-D study
- Doppler flow
When do you usually use a TEE?
Specialized evaluation of congenital cardiac abnormalities or when result of thoracic echocardiogram is suboptimal.
TEE are better for which impairments?
- atrial or ventricular septal defect
- complex valvular heart disease and endocarditis
- atrial enlargement with suspected atrial blood clots
- intracardiac tumours
What are the common criteria to stop a stress test?
- maximum possible performance
- emergence of sign and symptoms
- achievement of predetermined end point
In a stress test, an underwriter should consider?
- type of exercise protocol use
- stage and time exercise were concluded
- max heart and BP rate
- reason of termination
- maximal ST-segment depression and slope of ST-segment depression
- workload measurement
- length of time ST changes persist into recovery phase
- presence of arrhythmias
What are the common abnormal response on a stress test?
- reduced exercise capacity
- changes in BP
- changes in HR
- unusual symptoms
What ST-segment changes are likely related to CAD?
- ST-segment depression at peak exercise is greater than 1-1.5mm
- ST-segment change occurs early in the test
- ST-segment change occurs in multiple rather than in single EKG leads
- ST-depression persists longer than one minute into the recovery phase of the test.
