Global burden of Cardiovascular disease
• Up to 80% of heart disease, stroke and type 2 diabetes and over a third of the most common cancers could be prevented by eliminating obesity, unhealthy diets and physical inactivity
• Call for commitments at the global and national level to address these risk factors including:
– Control food supply, food information and marketing and promotion of energy-dense, nutrient-poor foods that are high in saturated, trans-fat, salt or refined sugars

*Data available from clinical trials or registries about the usefulness/efficacy in different subpopulations, such as gender, age, history of diabetes, history of prior myocardial infarction, history of heart failure, and prior aspirin use. A recommendation with Level of Evidence B or C does not imply that the recommendation is weak. Many important clinical questions addressed in the guidelines do not lend themselves to clinical trials. Even though randomized trials are not available, there may be a very clear clinical consensus that a particular test or therapy is useful or effective.
†In 2003, the ACC/AHA Task Force on Practice Guidelines developed a list of suggested phrases to use when writing recommendations. All guideline recommendations have been written in full sentences that express a complete thought, such that a recommendation, even if separated and presented apart from the rest of the document (including headings above sets of recommendations), would still convey the full intent of the recommendation. It is hoped that this will increase readers’ comprehension of the guidelines and will allow queries at the individual recommendation level.

• Balance calorie intake and physical activity to achieve or maintain a healthy body weight• Consume a diet rich in fruits and vegetables• Consume whole-grain, high-fiber foods• Consume fish, especially oily fish, at least twice a week• Limit intake of saturated fat to <7%, trans fat to <1% of energy, and cholesterol <300 mg/day by:
– Choosing lean mean and vegetable alternatives– Choosing fat free (skim), 1% fat, and low-fat dairy products,– Minimizing intake of partially hydrogenated fats
• Minimize intake of beverages and foods with added sugar• Choose and prepare foods with little or no salt (AHA 2011 rec. <1500mg/d)• If alcohol is consumed, do so in moderation

Primary Prevention
Women should consume a diet rich in fruits and vegetables; choose whole-grain, high-fiber foods; consume fish, especially oily fish,* at least twice a week; limit intake of saturated fat to <10% of energy, and if possible to <7%, cholesterol to <300 mg/d, alcohol intake to no more than 1 drink per day, and sodium intake to <2.3 g/d (approximately 1 tsp salt). Consumption of trans-fatty acids should be as low as possible (eg, <1% of energy)
*Pregnant and lactating women should avoid eating fish potentially high in methylmercury

Dietary Guidelines
I IIa IIb III
Reduce intake of saturated fats (to <7% of total calories), trans-fatty acids, and cholesterol (to <200 mg per day).
Encouraging consumption of omega-3 fatty acids in the form of fish or in capsule form (1 gram per day) for risk reduction may be reasonable for patients with known CAD.

You Can Now Receive Medicare Reimbursement for Nutrition Counseling
• The Centers for Medicare and Medicaid Services (CMS) has issued a decision memorandum that will allow you to be reimbursed for providing Medicare beneficiaries with intensive behavioral therapy for obesity, defined as a body mass index (BMI) ≥30.
• The agency suggests that more than 30% of the Medicare population will likely qualify for the new benefit.
Intensive behavioral therapy for obesity consists of the following:
• Screening for obesity in adults using BMI measurement calculated by dividing weight in kilograms by the square of height in meters (expressed in kg/m2)
• Dietary (nutritional) assessment• Intensive behavioral counseling and behavioral therapy
to promote sustained weight loss through high intensity interventions on diet and exercise
To be eligible for reimbursement, the counseling should follow the “Five-A’s” format:
• Assess: Ask about/assess behavioral health risk(s) and factors affecting choice of behavior change goals/methods.
• Advise: Give clear, specific, and personalized behavior change advice, including information about personal health harms and benefits.
• Agree: Collaboratively select appropriate treatment goals and methods based on the patient’s interest in and willingness to change the behavior.
• Assist: Using behavior change techniques (self-help and/or counseling), aid the patient in achieving agreed-upon goals by acquiring the skills, confidence, and social/environmental supports for behavior change, supplemented with adjunctive medical treatments when appropriate.
• Arrange: Schedule follow-up contacts (in person or by telephone) to provide ongoing assistance/support and to adjust the treatment plan as needed, including referral to more intensive or specialized treatment.
• Providing that a Medicare beneficiary is obese, competent, and alert at the time that counseling is provided and whose counseling is furnished by a qualified primary care physician, or other primary care practitioner, and in a primary care setting, CMS covers:
• One face-to-face visit every week for the first month• One face-to-face visit every other week for months 2-6• One face-to-face visit every month for months 7-12, if the beneficiary
meets the 3 kg weight loss requirement as discussed below• At the six-month visit, you must reassess the patient’s obesity and
document the amount of weight lost. To be eligible for additional face-to-face visits occurring once a month for an additional six months, patients must have lost at least 3 kg (6.6 lbs) over the course of the first six months of intensive therapy and should be documented in the record. For patients who do not achieve this minimum weight loss during the first six months of intensive therapy, a reassessment of their readiness to change and BMI is appropriate after an additional six-month period.

The term “Psychosocial”
broadly categorizes factors which are:
• Psychologic – e.g, anxiety, depression• Psychosocial – e.g., work stress,
discrimination, emotional support• Social-structural – e.g., socioeconomic
status, social integration, neighborhood effects
Screening for Psychosocial Risk: AHA Science Advisory on Depression
(Lichtman J et al. Circulation 2008)• The recommendations, which are endorsed by
the American Psychiatric Association, include:– early and repeated screening for depression
in heart patients– the use of two questions to screen patients –
if depression is suspected the remaining questions are asked (9 questions total)
– coordinated follow-up for both heart disease and depressive symptoms in patients who have both.

CONCLUSIONS
1)The increasing epidemic of obesity, diabetes, and inadequate attainment of CVD prevention goals necessitates improved efforts at therapeutic lifestyle management.2)Therapeutic lifestyle changes are a crucial and necessary part of any cardiovascular risk reduction effort3)Healthcare providers and facilities need to provide patients with adequate access to lifestyle experts, including registered dietitians, exercise specialists, and stress management personnel to address lifestyle-associated CVD risk in patients4)Recent legislation allowing for wider reimbursement for lifestyle management, medical nutrition therapy in particular, should be a motivation for healthcare providers to ensure that these resources are available.
