摘 要:目的 探讨我国人群长期血压变化及其与心血管病发病风险的关系.方法 入选中国多省市心血管病队列研究(CMCS)中参加1992—1993年和2007年2次心血管病危险因素调查并随访至2013年12月31日的研究对象5752人.根据2次调查中的血压水平进行分组.采用竞争风险模型分析15年血压变化与20年急性心血管事件、急性冠心病事件和卒中事件风险的关系.结果 入选的5752人中基线血压〈130/80 mmHg(1 mmHg=0.133 kPa)、130~139/80~89 mmHg及高血压(收缩压≥140 mmHg和/或舒张压≥90mmHg,或口服降压药物)者分别有2892人(50.3%)、1328人(23.1%)和1532人(26.6%).15年间,基线血压130~139/80~89 mmHg的人群中有870人(65.5%)进展为高血压,279人(21.0%)仍维持在该水平.调整了年龄、性别、体重指数、吸烟、糖尿病、总胆固醇和高密度脂蛋白胆固醇后,与血压一直维持在〈130/80 mmHg的人群相比,15年间血压维持在130~139/80~89 mmHg的人群急性心血管事件、急性冠心病事件和卒中事件发病的风险比(HR)和95%CI分别是2.04(1.16,3.57)、3.29(1.30,8.35)和1.63(0.80,3.33);进展为高血压者急性心血管事件、急性冠心病事件和卒中事件发病的HR和95%CI分别是2.81(1.84,4.29)、3.17(1.43,7.03)和2.71(1.65,4.44).结论 血压长期处于130~139/80~89 mmHg的人群进展为高血压的风险较高,血压长期处于130~139/80~89 mmHg及高血压患者心血管病发病风险也较高,应注意早期预防.Objective To explore the association between long-term changes in blood pressure (BP) levels and the incidence of cardiovascular diseases (CVD). Methods A total of 5752 participants, who participated baseline examination in 1992-1993 and re-examination in 2007, were followed up till December 31, 2013 according to the study protocol of the Chinese Multi-provincial Cohort Study. Participants were stratified by baseline BP and re-examination BP and cross-combined into 9 subgroups. The 20-year incidence of acute cardiovascular events, acute coronary heart disease (CHD) and acute stroke events were analyzed and association between disease incidence and 15-year changes in BP were determined using the competing risk regression model. Results (1) There were 523 CVD events (170 CHD, 373 stroke) during the 20 years follow up. The number of participants with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) of〈130/80 mmHg (1 mmHg=0.133 kPa), 130-139/80-89 mmHg, and hypertension were 2892 (50.3%), 1328 (23.1%) and 1532 (26.6%), respectively. (2) Among participants with baseline SBP of 130-139 mmHg or DBP of 80-89 mmHg, 870 (65.5%) progressed to hypertension and 279 (21.0%) maintained at the same stratum over a 15-year follow up period. (3) After adjustment for age, sex, body mass index, smoking status, diabetes, total cholesterol, and high-density lipoprotein cholesterol at baseline, participants maintained SBP/DBP at 130-139/80-89 mmHg had a higher risk of developing acute cardiovascular events, CHD and stroke with the hazard ratios (HR) and 95%confidence interval (95%CI) of 2.04 (1.16, 3.57), 3.29 (1.30, 8.35) and 1.63 (0.80, 3.33), compared with those who maintained their SBP〈130 mmHg and DBP 〈80 mmHg. Participants whose BP increased from 130-139/80-89 mmHg to hypertension over the follow up period had 2.81-fold (1.84, 4.29), 3.17-fold (1.43, 7.03) and 2.71-fold (1.65, 4.44) higher ris
