中老年原发性高血压病患者静息心率水平与心脑血管事件的相关性分析

Correlation analysis of resting heart rate with cardiac-cerebral vascular events in middle-aged and elderly patients with primary hypertension

目的:分析中老年原发性高血压患者静息心率水平与心脑血管事件的相关性。方法:对382例原发性高血压单纯并发各种心脑血管事件的患者进行收缩压(SBP)、舒张压(DBP)和静息心率(RHR)测定,并根据RHR的测量结果分为三组(R1组<75次/min,R2组为75～84次/min,R3组≥85次/min),统计各组并发脑出血、脑梗死、心力衰竭、心肌梗死和蛛网膜下腔出血的人数并进行比较。结果:原发性高血压患者并发心脑血管事件发生率随着静息心率水平的升高而增加(P<0.05)。结论:静息心率水平与原发性高血压患者并发心脑血管事件密切相关,是一个重要的危险因素。

Objective： To analyze the correlation between resting heart rate （RHR） and cardiac-cerebral events in the middle-aged and elderly patients with primary hypertension. Methods： 382 elderly primary hypertension patients complicated with various cardiac-cerebral vascular events were determined SBP, DBP and RHR, and divided into three groups according to the level of RHR, R1 group （RHR〈75 beats/min）, R2 group （75 bcats/min〈RHR〈84 beats/min） and R3 group （RHR ≥ 85 beats/rain）. The number complicated with cerebral hemorrhage, cerebral infarction, heart failure, cardiac muscle infarction and subarachnoid hemorrhage in every group was counted and compared. Results： With the increasing of the level of RHR, the incidence of cardiac-cerebral events increased gradually （P〈0.05）. Conclusion： The RHR of patients with hypertension is related to cardiac-cerebral events and is an important risk factor.
