CBC
CMP + Mg
Fasting BG/A1C
Lipids
TSH
UA/Microalbumin
BNP
37
Q

What additional testing might you consider in HF?

A
Fasting transferritin
ANA
HIV
Lyme antibody
Cardiac biopsy
38
Q

Which 8 diagnostic tests could be used in HF?

A
ECT EST
Echo stress
Med stress test (Radionuclide perfusion imaging)
Cardiac Cath
Coronary Calcium
Cardiac CT
Cardiac MRI
Impedance cardiography (noninvasive hemodynamic monitoring)
39
Q

What can be helpful in risk stratifying a patient with possible CAD?

A

Coronary Calcium

40
Q

If avoiding a cardiac cath, what test can be used to look for narrowing of arteries?

A

Cardiac CT

41
Q

Not widely available for use in the clinical setting. Test used mainly for research purposes.

A

Cardiac MRI

42
Q

What test can be used to help assess fluid status when making medication adjustments?

A

Impedance cardiography (noninvasive hemodynamic monitoring)

43
Q

Why is polysomnography considered in HF testing?

A

Sleep testing is used b/c obstructive sleep apnea can both cause and worsen symptoms of HF.
