动态血压心电图同步监测评价高血压患者的无症状性心肌缺血

目的:采用动态血压心电图同步监测评价高血压患者无症状心肌缺血(SMI)发作与左室肥厚(LVH)的关系。方法:我科2002年7月至2004年12月收治的25例存在LVH的原发性高血压患者(LVH组),同期选择与之性别、年龄(±3岁)、吸烟、糖尿病和应用β受体阻滞剂相匹配的无LVH的25例高血压患者作为对照(NLVH组),比较两组患者动态血压和动态心电图结果。结果:(1)即使两组患者在年龄、血脂水平、收缩压和舒张压方面比较差异无统计学意义,LVH组有16例发生了SMI,占64%,而NLVH组有7例发生了SMI,占28%,二者比较差异有统计学意义(P<0.05)。(2)有SMI的患者白天和夜间的心率均较无SMI患者快(P均<0.01),LVH患者白天和夜间的心率均较NLVH患者快(P均<0.05)。(3)LVH组中有8例患者的血压保持正常的昼夜节律,NLVH组中有20例患者的血压保持正常的昼夜节律,二者比较差异具有统计学意义(P<0.01)。结论:(1)即使两组患者在性别、吸烟、糖尿病、是否应用β受体阻滞剂等方面比较差异无显著性,在年龄、血脂水平、收缩压和舒张压方面比较差异无统计学意义,合并LVH的高血压患者仍较N...

Roles of 24h combined ambulatory blood pressure and ECG monitoring in the diagnosis of silent myocardial ischaemia in essential hypertensives

Objective To evaluate the roles of 24h combined ambulatory blood pressure and ECG monitoring in the diagnosis of silent myocardial ischaemia(SMI) and left ventricular hypertrophy(LVH) in essential hypertensives. Methods Twenty-five hypertensive patients with echocardiographic LVH admitted from July 2002 to Dec.2004 were recognized as LVH group and another 25 non-LVH hypertensive patients matched in age, sex, smoking, diabetes mellitus and β-blockers therapy as control group. All were monitored by 24h combin...
