Abbreviations: ACEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin receptor blocker; ASCVD, atherosclerotic cardiovascular disease; BMI, body mass index (calculated as weight in kilograms divided by the height in meters squared); CAC, coronary artery calcium; CCB, calcium channel blocker; CHD, coronary heart disease; eGFR, estimated glomerular filtration rate; HDL-C, high-density lipoprotein cholesterol; MetS, metabolic syndrome; NA, not applicable; PCE, pooled cohort equation; SBP, systolic blood pressure.
SI conversion factors: To convert total cholesterol and HDL-C to millimoles per liter, multiply by 0.0259.
Data are presented as number (percentage) unless otherwise indicated.
P value represents test for differences among 3 main disease groups (diabetes, MetS, and neither condition).
Some patients were taking multiple classes of medications, and the percentages may not represent the total number of patients taking antihypertensive medications.
