摘要
目的 探讨血压升高及降低与发生心肌缺血、心律失常之间的关系 ,为临床治疗提供依据。方法 5 6例高血压病患者同步检测 2 4h动态血压 (ABP)和动态心电图 (DCG) ,分析其血压升高及降低与发生ST -T改变、心律失常之间的关系。结果 (1) 6 0 .7% (34例 )轻、中度 (1、2级 )动态高血压和 2 6 .8% (15例 )ABP升高 ,6 4 .3% (36例 )血压昼夜节律消失 ,76 .8% (43例 )呈非杓型ABP曲线 ;(2 )DCG有多种异常改变 ,以ST -T改变 (2 8.6 %、5 1.8% )和房、室性心律失常 (6 7.9%、37.5 % )较多见 ;(3)ST -T改变和房、室性心律失常与ABP最高值及白昼最低值有显著相关性 (P <0 .0 5或P <0 .0 1) ,而与夜间最低值无相关性 (P >0 .0 5 ) ,收缩压、舒张压之间无差异。结论 本组患者 87.5 %血压控制不满意 ,6 4 .3%有心脏等靶器官损害 ,显示血压升高及白昼血压降低与显著ST -T改变和较复杂房。
Objective To evaluate the relation ships between increase or decrease in blood pressure and cardiac ischemia or arrythmia in essential hypertention.Methods In 56 patients with essential hypertension;24-hour blood pressure(BP) and Holter ECG were recorded.Results Slight and moderate increases and marked increase in ABP were found in 34(60.7%) and 15 patients(26.8%),respectirely.ABP curve was of non-dipper-like pattern in 43 patients(76.8%).Circadian rhythms of BP disappeared in 36 patients(64.3%).ST-T changes and arrythmia were found for 37 and 60 person-times respectively;they significantly correlated with highest ABP or lowest day time BP.The patients with non-dipper-like ABC curve had a higher prevalence of ST-T changes or arrythmia.Conclusions In essential hypertension, the extent of increase or decrease in blood pressure is related to cardiac ischemia and arrythima.
