Cardiometabolic Risk
1
Learning ObjectivesDefine cardiometabolic risk and assess the non-modifiable and modifiable risk factors
Describe methods for early identification and management of the following risk factors:ObesityDyslipidemiaHypertension
Speaker Notes2
Why Focus on Cardiometabolic Risk?A comprehensive approach to patient care
Multiple disease pathways and risk factors are considered to facilitate earlier intervention
Early assessment and targeted intervention are needed to treat and prevent all risk factors associated with cardiovascular diseases (CVD) and diabetes Daly A, Power MA. Medical Nutrition Therapy.

Indonesian Cardiometabolic Risk: CVD EpidemiologyCVDs are responsible for over 17.3 million deaths/year and are the leading causes of death in the world
Indonesian statistics:CVD Mortality Rates: 363-443/100 000 for males and 181-281/100 000 for femalesBurden of CVD (Disability-adjusted Life Year): 3315-4228/100000 for males and 2584-3438/100000 females

Insulin Resistance Syndrome
Cardiometabolic risk identifies individuals at high risk for cardiovascular disease (CVD)
Risk factors include traditional CVD risk factors such as abnormal LDL cholesterol but also include metabolic factors such as abdominal adiposity, insulin resistance, metabolic dyslipidemia (hypertriglyceridemia, low levels of HDL, small dense LDL), hypertension, prothrombic state and proinflammatory state
Identification of these components helps patients make lifestyle changes needed to decrease their risk of developing CVD and diabetes

Factors Affecting Insulin Resistance
Impaired Fasting Glucose (IFG): A condition in which the blood glucose level is between 100 mg/dL to 125mg/dL after an 8- to 12-hour fast.
Impaired Glucose Tolerance (IGT): A condition in which the blood glucose level is between 140 and 199 mg/dL at 2 hours during an oral glucose tolerance test (OGTT).

Associated Risk FactorsFasting Blood Glucose
As prediabetes develops into T2DM, the continued output of glucose and glucose from the intestinal tract leads to hyperglycemia (increased FBG). Simultaneously, insulin resistance is increased (decreased insulin sensitivity) and insulin secretion is reducedT2DM is an independent risk factor for CVD in addition to coexisting conditions like hypertension, dyslipidemia and obesity which are risk factors in themselves

Prediabetes and Diabetes Prevention
Prediabetes Pre-diabetes is an important risk factor for future diabetes and CVD
Recent studies have shown that lifestyle modifications can reduce the rate of progression from pre-diabetes to diabetes
Impaired Fasting Glucose (IFG) and Impaired Glucose Tolerance (IGT)ADA Consensus Statement:Treat IFG and IGT with intensive lifestyle modification
For certain patients with both IFG & IGT and risk factor(s), consider addition of metformin
Nathan D, et al. Impaired Fasting Glucose and Impaired Glucose Tolerance: Implications for Care. Diabetes Care 2007;30:753-9.
Lifestyle modification:5-10% weight loss and moderate intensity physical activity approx 30 mins/day
Risk factors include:6.0%

METHODS:3234 andomly assigned nondiabetic persons with elevated FBG and PPG to placebo, metformin (850 mg twice daily), or a lifestyle-modification program Goals: at least 7 percent weight loss and at least 150 minutes of physical activity/week.RESULTS:The average follow-up was 2.8 years. The incidence of diabetes was 11.0, 7.8, and 4.8 cases per 100 person-years in the placebo, metformin, and lifestyle groups, respectively. The lifestyle intervention reduced the incidence by 58% and metformin by 31%, as compared with placebo Lifestyle intervention was significantly more effective than metformin. To prevent one case of diabetes during a period of three years, 6.9 persons would have to participate in the lifestyle-intervention program, and 13.9 would have to receive metformin.CONCLUSIONS:Lifestyle changes and treatment with metformin both reduced the incidence of diabetes in persons at high riskLifestyle intervention was more effective than metformin.

Screening Screening is conducted on those who have diabetes risks, but do not show any symptoms of DM.
Screening seeks to capture undiagnosed DM or prediabetes so it can be managed earlier and more appropriately.
Mass screening is not recommended considering the costs (usually abnormal results are not followed-up with an action plan).

Standard Values of Random BG and FBG for Screening and Diagnosis of DMNote: For high-risk groups which show no abnormal results, the test should be done every year. For those aged > 45 years without other risk factors, screening can be done every 3 years.Non DMUncertain DMDMRandom Blood Glucose Level (mg/dL)Venous Plasma 90 cmInternational Diabetes Federation.
