tion, and Treatment of High Blood Pressure.4 The 2017 guidelines removed the classification of “prehypertension,” added diagnoses of “elevated blood pressure” for systolic blood pressure (SBP)=120 to 129 mmHg with diastolic blood pressure (DBP) <80 mmHg, and reduced the threshold for diagnosing stage I hypertension to SBP=130 to 139 mm Hg or DBP=80 to 89 mm Hg. The treatment recommendation for elevated blood pressure and stage I hypertension, with Atherosclerotic Cardiovascular Dis- ease (ASCVD) risk score <10%, is nonpharmacological, lifestyle-only treatment (see Figure A). An estimated 21% of US adults (≈53 million) meet the 2017 guidelines cri- teria for lifestyle-only treatment, including 12% of adults with elevated blood pressure and 9% who are diagnosed with stage I hypertension but have an ASCVD risk score of <10% (see Figure A, light gray box).5 The 2018 AHA/ACC Guideline on the Management of Blood Cholesterol3 updated the 2013 guidelines.6 This update continues to advocate lifestyle-only approaches for adults 40 to 75 years of age with low-density lipopro- tein cholesterol (LDL-C) >70 mg/dL and low ASCVD risk scores (<7.5%). The update also clarifies that for similarly aged adults with LDL-C >70 mg/dL, intermediate ASCVD risk scores (7.5%–20%), low coronary artery calcium score (<100 Agatston units), and a low burden of other risk fac- tors (eg, LDL-C <160 mg/dL; free from metabolic syndrome, chronic kidney disease, inflammatory diseases, etc), lifestyle- only treatment is an option during the clinician/patient shared decision-making management approach.9 Although an exact figure is not available, we conservatively estimate that ≈28% of US adults (≈71 million) would meet the 2018 Cholesterol Clinical Practice Guideline criteria for lifestyle-only treatment using current US Census data and a report of statin eligibil- ity based on the 2013 cholesterol guidelines.7,8 This approx- imation includes adults 40 to 75 years of age with LDL-C >70 mg/dL and ASCVD risk score <7.5% (see Figure B). This estimate is conservative because it does not include the 9% of US adults (≈23 million) 40 to 75 years of age with LDL-C >70 g/dL but intermediate ASCVD risk scores. These
