Abstract: Importance: Practice guidelines recommend that clinicians engage patients in treatment decisions and explain atherosclerotic cardiovascular disease (ASCVD) risk but do not describe how to communicate this risk most effectively. Objective: To determine how the ASCVD risk time horizon, outcome, and presentation format influence risk perceptions and treatment preferences. Design, Setting, and Participants: From May 27, 2015, through November 12, 2015, participants from the Patient and Provider Assessment of Lipid Management Registry at 140 US cardiology, primary care, and endocrinology practices were presented 3 independent scenarios (representing the same hypothetical patient) and asked to rate their perceived risk and willingness to take medication to lower risk in light of (1) a 15% 10-year ASCVD event risk, (2) a 4% 10-year cardiovascular disease (CVD) death risk, and (3) a 50% lifetime ASCVD event risk. Exposures: Participants were randomized to receive risk estimates using numbers only, a bar graph, or a face pictogram. Results: Of 3566 eligible participants, 2708 (76.9%) responded (median age, 67 years [interquartile range, 61-76 years]; 280 [10.3%] African American; 1491 men [55.1%]). When shown the lifetime ASCVD risk, respondents were more likely to consider the risk "high to very high" than when presented the 10-year ASCVD risk or the CVD death risk (70.1% vs 31.4% vs 25.7%, respectively; both P?
