Abstract
Background— Factors leading differentially to the development of isolated diastolic (IDH), systolic-diastolic (SDH), and isolated systolic (ISH) hypertension are poorly understood. We examined the relations of blood pressure (BP) and clinical risk factors to the new onset of the 3 forms of hypertension. Methods and Results— Participants in the Framingham Heart Study were included if they had undergone 2 biennial examinations between 1953 and 1957 and were free of antihypertensive therapy and cardiovascular disease. Compared with optimal BP (SBP <120 and DBP <80 mm Hg), the adjusted hazard ratios (HRs) for developing new-onset IDH over the ensuing 10 years were 2.75 for normal BP, 3.29 for high-normal BP (both P<0.0001), 1.31 (P=0.40) for SDH, and 0.61 (P=0.36) for ISH. The HRs of developing new-onset SDH were 3.32, 7.96, 7.10, and 23.12 for the normal BP, high-normal BP, ISH, and IDH groups, respectively (all P<0.0001). The HRs of developing ISH were 3.26 for normal and 4.82 for high-normal BP (both P<0.0...
