目的分析老年高血压患者降压治疗后舒张压对心脑血管事件发生率的影响。方法回顾性分析医院接受高血压治疗240例患者的临床资料,按照患者降压治疗后的舒张压水平分为6个组。所有患者均接受降压治疗,后由专科医师或护理人员按照标准方法对测量上肢血压,取平均值。随访以观察、记录6组患者心脑血管事件发生情况。结果第2组心脑血管事件发生率最低,与第4、5、6组比较差异有统计学意义(P<0.05);与第1、3组比较心脑血管事件发生率有增加趋势,差异无统计学意义(P>0.05)。结论老年高血压患者降压治疗后心脑血管事件发生率会随着舒张压降低而呈现减少趋势,而65~69mm Hg为其最佳的舒张压状态,心脑血管事件发生率最低。
Objective To analyze the effect of diastolic blood pressure on the incidence of cardiovascular events in elderly hypertensive patients after antihypertensive treatment. Methods The clinical data of 240 patients with hypertension admitted to hospital were retrospectively analyzed. The patients were divided into 6 groups according to their diastolic blood pressure after antihypertensive treatment. All patients underwent antihypertensive treatment, followed by a specialist or paramedical measure of upper limb blood pressure according to standard methods, averaging. Follow-up to observe and record six groups of patients with cardiovascular events. Results The incidence of cardiovascular events was the lowest in group 2, which was significantly different from that in groups 4, 5 and 6 (P <0.05). Compared with groups 1 and 3, the incidence of cardiovascular and cerebrovascular events had an increasing trend, and the difference No statistical significance (P> 0.05). Conclusion The incidence of cardiovascular and cerebrovascular events after antihypertensive therapy in elderly patients with hypertension will decrease with the decrease of diastolic blood pressure. However, the optimal diastolic blood pressure is 65-69 mm Hg, and the incidence of cardiovascular and cerebrovascular events is the lowest.
