Cardiovascular disease (CVD) is a major cause of death in men and women in the U.S.1 Yet evidence-based strategies can reduce CVD risk, such as lipid-lowering therapy, healthful diet and physical activity, controlling high blood pressure, tobacco cessation and managing diabetes. Aspirin no longer has a role in primary prevention of CVD, especially in older adults.
This module helps primary care clinicians to apply evidence-based practices for the primary prevention of CVD, such as prescribing lipid-lowering therapy, recommending lifestyle interventions, and limiting the role of aspirin. Providing recommendations to prevent a first occurrence of CVD begins by understanding a patient’s CVD risk. A validated tool like the Pooled Cohort Equation (PCE), also called ASCVD Risk Estimator Plus, uses age, sex, race, blood pressure and related treatment, cholesterol, diabetes and smoking status to help determine risk.2
For primary prevention, in most cases the goal of statin therapy does not require achieving a given LDL level, as long as the patient takes the medication.
Risk factors can help determine if a statin is needed for a patient with intermediate risk. A coronary artery calcium (CAC) score may help patients in which risk is not clear decide on a statin. In older patients a CAC score may be less useful.4 See the Evidence Document above for more detailed information.
Older adults (age 75 and older) may still benefit from a statin. Don’t stop or withhold a statin based on age alone.5-7
Plant-predominant diets, such as the Mediterranean diet or DASH diet, can lower CVD risk by 25-30%.8,9 A combination of strength or resistance training and aerobic exercise has a large effect on CVD risk.
Using the 5 A’s can help start the conversation.
1. Assess the patient’s current behaviors and readiness for change.
2. Advise with recommendations tailored to a patient’s risk factors.
3. Agree on SMART goals that have clear links to action.
4. Assist the patient to overcome their own specific barriers.
5. Arrange follow-up with resources and support.
SMART goals provide a structure to create small, actionable goals that help patients change behaviors:
Specific: “What do you want to do?”
Measurable: “How will you know when you’ve reached it?”
Achievable: “Is it in your power to accomplish it?”
Realistic: “Can you realistically achieve it?”
Timely: “When exactly do you want to accomplish it?”
