The clinician must balance an understanding of a patient s estimated ASCVD risk with potential benefits and ad- verse risk from pharmacological therapy in the context of a risk discussion. To determine the appropriateness of pharmacological therapy after quantitative risk esti- mation in cases that are unclear, risk-enhancing factors or selective use of a coronary artery calcium measure- ment can inform decision-making for cholesterol-low- ering or antihypertensive medication use in intermedi- ate-risk individuals. This primary-prevention guideline strives to pro- vide clinicians with the information they need to help their patients reduce their risk of ASCVD and encour- age them to make healthier lifestyle changes when needed.
