BACKGROUND: Orthostatic hypertension is an emerging risk factor for adverse events. Recent consensus statements combine an increase in blood pressure upon standing with standing hypertension, but whether these 2 components have similar risk associations with cardiovascular disease (CVD) is unknown.
METHODS: The ARIC study (Atherosclerosis Risk in Communities) measured supine and standing blood pressure during visit 1 (1987-1989). We defined systolic orthostatic increase (a rise in systolic blood pressure [SBP] ≥20 mm Hg, standing minus supine blood pressure) and elevated standing SBP (standing SBP ≥140 mm Hg) to examine the new consensus statement definition (rise in SBP ≥20 mm Hg and standing SBP ≥140 mm Hg). We used Cox regression to examine associations with incident coronary heart disease, heart failure, stroke, fatal coronary heart disease, and all-cause mortality.
RESULTS: Of 11 369 participants (56% female; 25% Black adults; mean age, 54 years) without CVD at baseline, 1.8% had systolic orthostatic increases, 20.1% had standing SBP ≥140 mm Hg, and 1.3% had systolic orthostatic increases with standing SBP ≥140 mm Hg. During up to 30 years of follow-up, orthostatic increases were not significantly associated with any of the adverse outcomes of interest, while standing SBP ≥140 mm Hg was significantly associated with all end points. In joint models comparing systolic orthostatic increases and standing SBP ≥140 mm Hg, standing SBP ≥140 mm Hg was significantly associated with a higher risk of CVD, and associations differed significantly from systolic orthostatic increases.
CONCLUSIONS: Unlike systolic orthostatic increases, standing SBP ≥140 mm Hg was strongly associated with CVD outcomes and death. These differences in CVD risk raise important concerns about combining systolic orthostatic increases and standing SBP ≥140 mm Hg in a consensus definition for orthostatic hypertension.
