随着我国社会经济的快速发展及医疗水平的持续提高, 老年人的数量和比例不断增加, 冠心病的实际发病人数和患病后得以生存的人数不断增多, 导致二级预防的需求随之扩大。心脏康复以改善患者预后和生活质量为目标, 是冠心病二级预防的个体化策略, 其核心干预措施包括药物、运动、饮食、戒烟和心理等5个方面。本期以预防与康复为主题的数篇研究报告为我国心脏康复策略提供了多方面新的证据。这些新的证据不仅有助于提升临床医师对冠心病患者的非药物干预措施, 如心肺功能评估和指导下的体力活动、合理膳食的指导、戒烟指导和心理问题治疗的重视程度和专业化水平, 也促进我们对新政策和新策略的需求及其合理性和可行性的思考, 从而促进我国冠心病二级预防质量及可及性。

目的探究候鸟高血压患者的迁徙停留时间与其血压控制情况、血压水平之间的关系。方法本研究为横断面研究。在2022年10至11月, 从海南省五指山市社区内招募候鸟高血压患者, 采用结构式调查表收集其自测血压和停留时间。根据自测血压判断血压控制情况是否良好。采用限制性立方样条, 分析候鸟高血压患者停留时间与血压控制情况及自测血压水平之间的关联。结果共纳入362例候鸟高血压患者, 年龄为(69.7±7.0)岁, 男性169例(46.7%), 自测血压收缩压为(129.1±16.2)mmHg(1 mmHg=0.133 kPa), 舒张压为(78.9±10.1)mmHg, 血压控制率为48.1%(174/362), 在五指山的停留时间为7(6, 7)个月。候鸟高血压患者的停留时间与血压控制情况之间存在倒U型关联(总体:P=0.023;非线性检验:P=0.014), 停留时间为7个月时血压控制情况最佳。停留时间与收缩压之间存在着U型曲线关系(总体:P=0.001;非线性检验:P=0.033), 与舒张压之间存在线性负向关联(β=-1.19, P=0.003)。结论与停留时间过短或过长的候鸟高血压患者相比, 在五指山市停留时间在7个月左右的候鸟高血压患者血压控制情况好, 且收缩压低。
