Comorbidities Flashcards
Test for PAD (peripheral artery disease)
ABI (ankle brachial index)
Screening for Depression
Beck depression inventory (BDI)
ABI test
Measure BP in ankle and arm at rest, then repeat after 5 minutes walking in treadmill.
Uses a standard cuff and Doppler on the ankle.
ABI normal results vs. those with PAD
Normal: pressures the same
In PAD: ankle lower than arm (narrowing arteries)
Criteria for performing diagnostic ABI
Intermittent claudication Age over 50 Smoking Hypertension Dyslipidemia Diabetes >10 years
Lower extremity pain during physical activity that subsides with rest
Intermittent claudication
ADA blood pressure goals
<130/80 mmHg for diabetics
Recommendations for blood pressure between 130/80 and 139/89 mmHg in diabetic
Therapeutic lifestyle changes (weight loss, tobacco cessation, and limit sodium).
Recommendations for blood pressure >140/90 mmHg in diabetics
Add medication if either is above this limit, in addition to lifestyle intervention.
Which medication is considered first line for hypertension in diabetes?
ACE inhibitor (or ARB)
What lipid abnormalities are common with Diabetes?
Low HDL and elevated triglycerides
LDL goals for diabetics
<100 mg/dl, or less than 70 mg/dl in those with very high risk.
When should a statin be started in a diabetic?
> 135 mg/dl if no other risk factors. It should be started in ALL patients with any increased CV risk regardless of lipid levels.
What is the DPP?
Diabetes Prevention Program, a large multicenter study demonstrating onset of diabetes could be prevented/delayed when lifestyle modifications are implemented.
Outcome of the healthy eating and increasing physical activity (weight loss) in DPP?
58% decreased risk for developing diabetes
Recommendations based on DPP for preventing or delaying diabetes
- Reduce weight 5 to 7 %
- Low fat/high fiber diet
- 150 minutes exercise/week
Microalbuminuria test: Spot Urine
Measures albumin to creatinine ratio.
Most common method
Normal less than 30 mcg/dl
Microabuminuria test: 24 hour urine
Compares the simultaneous urine and serum creatinine clearance
Microabuminuria test: timed urine
i.e. overnight or 4 hours
What does creatinine clearance estimate?
GFR-glomerular filtration rate
Depends on timed urine sample (usually 24 hours), provides direct method of estimating GFR.
How is SCr used to measure renal function?
Serum creatinine is used to estimate GFR indirectly, calculated on patient age and weight. Subtle changes can herald major loss of renal function.
How is BUN used to measure renal function?
Measures Blood Urea Nitrogen to indirectly measure GFR.
Less sensitive marker of early diabetic nephropathy, used with SCr to monitor renal function on a daily basis, and inexpensive/easy test.
What is microalbumin?
Protein normally absent in urine or in small amounts when kidney function is normal.
Why do the MAU?
Microalbuminuria tests for kidney functions, to detect early microalbuminuria to prevent or delay kidney function.
