[OP.2C.06] OPTIMAL BLOOD PRESSURE GOAL FOR THE ELDERLY CHINESE

Abstract Objective To investigate the prevalence status of the isolated systolic hypertension (ISH) among the elderly Chinese population and analyze risk factors of ISH. Methods The survey was conducted from September 2015 to September 2016 enrolling 1269 people aging above 80 in the urban community in Chengdu, China. The participants were recruited by using a stratified cluster sampling method. The average blood pressure of an individual was obtained by using a standardized mercury sphygmomanometer to measure the blood pressure twice after a 10-minute seated rest. Results The prevalence of ISH was 53.0% among the elderly population; the ISH was accounted for 82.2% of all hypertension cases. The prevalence of ISH of males and females was 54.7% and 51.5%, respectively, without significant differences (P = 0.25). The prevalence of ISH in the 80–84 group, 85–89 group, and > 90 group were 52.5%, 53.0%, and 60.0%, respectively without significant differences (P for trend = 0.36). Multivariate logistic regression analysis showed that drinking alcoholic, obesity, and heart rate (HR) > 75 beats/min were all positively correlated to the incident of ISH; however, physical exercise was negatively correlated to the occurrence of ISH. Conclusion 53.0% of the elderly Chinese population aged above 80 has ISH. The gender and physical exercise are not the independent risk factor of ISH. But drinking alcoholic, obesity and HR > 75 are significantly related to the occurrence of ISH.

Abstract OBJECTIVE Atrial fibrillation (AF) and hypertension are prevalent chronic disease conditions in the elderly population. In the present cross-sectional study, we investigated the association between blood pressure (BP) and AF in an elderly Chinese population. METHOD Our elderly (≥65 years) subjects were residents recruited from 6 communities in Shanghai from 2006 to 2017. Atrial fibrillation was systematically screened by rest 12-lead electrocardiogram (ECG) or by a handheld single-lead ECG. BP status was defined according to the European hypertension guidelines as optimal, normal, or high-normal BP, and stage 1, 2, or 3 hypertension. RESULT In the 6,966 participants (women 56.0%, mean age: 72.3 years), the prevalence of AF was 3.3%, and the prevalence of hypertension was 58.7% (83.7% treated). In all participants, the association with prevalent AF was negative for systolic BP (odds ratio [OR] per 10-mm Hg increase 0.79, 95% confidence interval [CI]: 0.71–0.88, P < 0.0001) but positive for diastolic BP (OR per 5-mm Hg increase 1.11, 95% CI: 1.02–1.22, P = 0.02). In untreated participants (n = 3,544), the association with prevalent AF was U-shaped for both systolic and diastolic BP, with the nadir at high-normal BP and a significantly higher risk of prevalent AF in optimal systolic BP (OR: 3.11, 95% CI: 1.65–5.85, P = 0.004) and stage 2 or 3 diastolic hypertension relative to the nadir (OR: 8.04, 95% CI: 2.28–28.3, P = 0.001). CONCLUSION In the elderly population, BP shows a complicated relationship with prevalent AF, with high-normal BP at the lowest risk and optimal systolic BP and stage 2 or 3 diastolic hypertension at increased risks.
