脑血流供应依赖于收缩压(Systolic blood pressure,SBP)水平,而心脏血流供应则依赖于舒张压(diastolic blood pressure,DBP)水平,据此我们推测:收缩压变异性(systolic blood pressure variability, SBPV)可能和卒中具有密切相关性,而舒张压变异性(diastolic blood pressure variability, DBPV)可能仅对心血管事件产生影响。
本研究所有数据来源于“血压与卒中临床结局的队列研究”(Blood Pressure and Clinical Outcome in Stroke Survivors, BOSS),BOSS研究为多中心(全国61家医院)、前瞻性、观察性研究,入组病例均为发病7天内的缺血性卒中和TIA患者,均使用统一发放的电子血压计(HEM-4030, OMRON Life Science Co. Ltd, Kyoto, Japan) 行每日2次血压监测,从入院后第1天连续监测至卒中后90天。血压变异性利用标准差和变异系数计算。临床结局定义为卒中后90天的非致死性卒中复发(脑梗死、脑出血)和心血管事件(心肌梗死、心绞痛、冠状动脉支架植入术、心力衰竭、心血管死亡)。采用COX回归模型检测血压变异性与卒中复发的相关性,以logistic回归模型进行血压变异性与心血管事件的相关性分析。
For patients with IS/TIA, stroke recurrence was associated with both SBPV and DBPV; however, cardiovascular events seem to be only related to DBPV.
Of 2325 patients with IS or TIA, 103 (4.43 %) experienced a recurrent stroke and 64 (2.75 %) had cardiovascular events within 3 months. Day-to- day SBPV was only associated with stroke recurrence (BPVSD: OR, 1.72, 95% CI 1.09 to 2.71; BPVCV: 1.86, 95% CI 1.19 to 2.92), but not cardiovascular events (BPVSD: 1.67, 95% CI 0.94 to 2.94; BPVCV: 1.51, 95% CI 0.86 to 2.64). However, DBPV seems to be related to both stroke (BPVSD: 1.60, 95% CI 1.02 to 2.49; BPVCV: 1.53, 95% CI 0.99 to 2.37) and cardiovascular events (BPVSD: 2.48, 95% CI 1.37 to 4.48; BPVCV: 1.92, 95% CI 1.09 to 3.36). Similar results were found at 1 year.
