Isolated systolic hypertension (ISH) is common in older adults and is a risk factor for incident heart failure (HF). We examined the association of systolic-diastolic hypertension (SDH) with incident HF and other outcomes in older adults.
In the Cardiovascular Health Study (CHS), 5776 community-dwelling adults≥65years had data on baseline systolic and diastolic blood pressure (SBP and DBP). We excluded those with DBP<60mmHg (n=821), DBP≥90 and SBP<140mmHg (n=28), normal BP, taking anti-hypertensive drugs (n=1138), normal BP, not taking anti-hypertensive drugs, history of hypertension (n=193), and baseline HF (n=101). Of the remaining 3495, 1838 had ISH (SBP≥140 and DBP<90mmHg) and 240 had SDH (SBP≥140 and DBP≥90mmHg). The main outcome was centrally-adjudicated incident HF over 13years of follow-up.
Participants had a mean (±SD) age of 73 (±6)years, 57% were women, and 16% African American. Incident HF occurred in 25%, 22% and 11% of participants with ISH, SDH and no hypertension, respectively. Compared to no hypertension, multivariable-adjusted hazard ratios (HR) and 95% confidence intervals (CI) for incident HF associated with ISH and SDH were 1.86 (1.51-2.30) and 1.73 (1.23-2.42), respectively. Cardiovascular mortality occurred in 22%, 24% and 9% of those with ISH, SDH and no hypertension, respectively with respective multivariable-adjusted HRs (95% CIs) of 1.88 (1.49-2.37) and 2.30 (1.64-3.24).
Among older adults with hypertension, both SDH and ISH have similar associations with incident HF and cardiovascular mortality.
单纯收缩期高血压（ISH）在老年人中很常见，是发生心力衰竭（HF）的危险因素。我们研究了收缩期-舒张期高血压（SDH）与老年人发生HF及其他结局的关联。
在心血管健康研究（CHS）中，5776名年龄≥65岁的社区居住成年人有基线收缩压和舒张压（SBP和DBP）数据。我们排除了舒张压<60mmHg者（n = 821）、舒张压≥90mmHg且收缩压<140mmHg者（n = 28）、血压正常且服用降压药者（n = 1138）、血压正常且未服用降压药但有高血压病史者（n = 193）以及基线时患有HF者（n = 101）。在其余3495人中，1838人患有ISH（收缩压≥140mmHg且舒张压<90mmHg），240人患有SDH（收缩压≥140mmHg且舒张压≥90mmHg）。主要结局是在13年随访期间经中心判定的HF发病情况。
参与者的平均（±标准差）年龄为73（±6）岁，57%为女性，16%为非裔美国人。ISH、SDH和无高血压的参与者中，HF发病率分别为25%、22%和11%。与无高血压相比，ISH和SDH相关的HF发病的多变量调整风险比（HR）及95%置信区间（CI）分别为1.86（1.51 - 2.30）和1.73（1.23 - 2.42）。ISH、SDH和无高血压者的心血管死亡率分别为22%、24%和9%，各自的多变量调整HR（95%CI）分别为1.88（1.49 - 2.37）和2.30（1.64 - 3.24）。
在患有高血压的老年人中，SDH和ISH与HF发病及心血管死亡率的关联相似。
