该研究的目的是评估作为高血压危险因素的早发型与迟发性高血压症状对后代和心血管死亡的影响。

该研究设计多代、前瞻性队列研究。建立Framingham心脏研究。研究人员对社区住院的两代参与者进行了六十年的连续检查血压测量:3614名具有死亡率数据的第一代参与者和1635名初次非高血压第二代参与者(其父母血压数据已知)。主要研究指标是父母早发型高血压(年龄<55岁)与子代高血压发病率之间的关系。并采用回归分析,分析高血压发病年龄与病例特异性死亡率(心血管死亡)与控制(非心血管死亡)的关系。

结果显示,在第二代参与者中(其中父母单方或双方均有早发性高血压),与父母没有高血压的参与者相比,高血压的风险没有增加;相比之下,高血压危险比分别为2.0(95%置信区间1.2至3.5)和3.5(1.9至6.1)。在第一代死因中,发生1151例心血管死亡(包括630例冠心病)。心血管死亡的几率随着高血压发病年龄的降低呈线性增加(P <0.001)。与非高血压参与者相比,年龄<45岁的高血压发生心血管死亡的优势比为2.2(1.8至2.7),冠状动脉死亡为2.3(1.8至2.9),而年龄≥65岁的高血压发病率较低心血管死亡的1.5(1.2-1.9),冠心病死亡1.4(0.98-1.9)(高血压发病年龄<45岁,年龄≥65岁时差异有显着性差异(P≤0.002))。

结论表明,父母的早发型和非迟发性高血压与后代的高血压密切相关。反之,与晚发型高血压相比,早期高血压发作与有极大可能导致心血管(特别是冠状动脉)疾病的死亡。这些发现表明,在评估个体的高血压风险时,将早发型和晚期发作高血压区分为家族性状是重要的,并且在评估具有明确高血压的成人心血管结局的风险时作为特定类型的血压特征是重要的。
