- Patients with prediabetes should be referred to an effective ongoing support program targeting weight loss of 7% of body weight and increasing physical activity to at least 150 min/week of moderate activity, such as walking.
- Follow up counseling appears to be important for success.
- Metformin therapy for prevention of type 2 diabetes may be considered in those with impaired glucose tolerance (IGT), impaired fasting glucose (IFG), or an A1C 5.7-6.4%, especially for those with BMI > 35 kg/m2, aged <60 years, and women with prior gestational diabetes.
Hypertension leads to elevated risk for myocardial infarction, stroke, eye problems and kidney disease. Often a silent disease, many patients won't know they have high blood pressure until informed by their health care provider.
For patients without diabetes:
- Blood Pressure should be measured at each regular visit or at least once every 2 years if it is less than 120/80 mmHg
- Blood Pressure should be measured while seated after 5 min rest in office
For patients with diabetes:
- Blood Pressure should be measured at each regular visit
- Blood Pressure should be measured while seated after 5 minutes rest in office
- Patients with ;::1 30 or ;;:80 mmHg should have Blood Pressure confirmed on a separate day
DASH (Dietary Approaches to Stop Hypertension) diet
High in whole grains, fruits, vegetables, and low-fat dairy
Low in saturated and trans fat, cholesterol
Weight loss, if applicable
If Blood Pressure ;::140/ ;;:90 mm Hg, drug therapy is indicated
- Combination therapy often necessary
- Treatment should include ACE or ARB
- Thiazide diuretic may be added to reach goals
- Monitor renal function and serum potassium

Abnormal Lipid Metabolism
Inform patients of the health risks of both high LDL cholesterol and low HDL cholesterol, as well as triglycerides. Patients should also be aware that modest weight loss and increased physical activity can have a beneficial effect on lipid management.
- In adults (> 19 years) without diabetes, test at least every 5 years, including adults with low-risk values. Low-risk values are:
- LDL <100 mgdL
- HDL >40 mgdL for men and
- >50 mgdL for women
- Triglycerides <150 mgdL)

Inflammation & Hypercoagulation
Proinflammatory/prothrombotic factors are known to underlie cardiometabolic risk. Inflammation is a major component of atherogenesis and other cardiometabolic problems. Creactive protein (CRP), an emerging marker of inflammation, may provide useful information to assess CVD risk, but trials documenting its clinical utility have not been completed. This may give a more complete picture of risk.
High-sensitivity CRP (hs-CRP) tests may be used to further evaluate patients' underlying risk, especially for patients otherwise at indeterminate risk.
Relative risk categories for hs-CRP levels:
- Low risk <1 mg/L
- Average risk 1-3 mg/L
- High risk> 3 mg/L
Patients with hs-CRP levels in the high end of the normal range have 1.5 to 4 times the risk of having MI than those with CRP values at the low end of the normal range. Weight loss, aspirin and statins have been shown to reduce CRP levels, however, at this point, no controlled prospective trials have shown the benefit of CRP lowering.
More research is needed to establish hypercoagulation as a solid indicator of risk, to determine the positive predictive value of the test, and to standardize assays.

35% of coronary heart disease deaths in the United States can be attributed to an inactive lifestyle, and consistent exercise can reduce CVD risk.
Staying active can:
- Increase insulin sensitivity
- Improve lipid levels
- Lower blood pressure
- Aid weight management
- Improve blood glucose management in type 2 diabetes \ Lower risk of CVD
- Encourage your patients to find ways to fit activity into their daily routine. Examples include taking the stairs, parking further away, taking the stairs instead of elevator, or walking to another bus stop.
- Encourage patients to aim for at least 150 minutes/week of moderate aerobic exercise. This can be broken down into multiple spurts of activity each day. If they are just starting out, encourage them to start with just 5 or 10 minutes, 3x per day and build from there.
- Many patients are motivated by wearing a pedometer and tracking their steps. Encourage them to join a walking group and challenge each other to more and more steps. A good online group exists at diabetes.org/ClubPed

Most patients know smoking is bad for their health, but quitting is often easier said than done. If you have patients who smoke, be sure to emphasize not only the grave dangers of continuing smoking, but also the tremendous benefits of quitting.
- Obtain documentation of history of tobacco use
- Ask whether smoker is willing to quit
- If no, initiate brief, motivational discussion regarding:
- The need to stop using tobacco
- Risks of continued use
- Encouragement to quit, as well as support when ready
- If yes, assess preference for and initiate either minimal, brief, or intensive cessation counseling.
