高血压患者血压昼夜节律与左室舒张功能障碍的关系探讨.pdf

提要

目的:采用美国产 ABMP 型无创性便携式动态血压监测仪对高血压患者进行血
压昼夜节律变化分析,应用心脏超声技术检查高血压患者的左室舒张功能,探讨高血
压患者血压昼夜节律变化与左室舒张功能障碍的关系。
方法:对 70 例高血压患者行动态血压监测,监测受试者的血压昼夜节律,并依
据其血压昼夜节律对高血压患者进行分组。对 70 例高血压患者及 40 例健康者行心脏
超声检查,利用二尖瓣血流频谱和二尖瓣多普勒组织成像测量受试者的各项指标,评
估左室舒张功能。比较高血压昼夜节律各组及对照组的二尖瓣血流频谱和二尖瓣多普
勒组织成像指标,对高血压患者血压昼夜节律变化与左室舒张功能障碍进行相关性分
析。
结果:,高血压昼夜节律各组的二尖瓣血流频谱和二尖瓣多普勒
组织成像指标有明显差异(P<)。2. 高血压患者血压昼夜节律变化与二尖瓣血流
频谱及二尖瓣多普勒组织成像有明显相关性(P<)。
结论:,二尖瓣血流频谱及
多普勒组织成像的多项指标数值有明显差异,提示高血压对心脏的损害。2. 高血
压患者血压昼夜节律变化与左室舒张功能障碍有明显相关性,提示在高血压病发生
发展过程中,“非勺型”患者的左室舒张功能障碍发生率高于“勺型”患者,说明
高血压“非勺型”对心脏损害要重于“勺型”; 血压昼夜节律变化可作为高血压患
者左室舒张功能障碍的独立危险因素。3. 重视动态血压监测及超声心动图检查对
于研究高血压病的发生及发展具有重要意义。

ABSTRACT

Objective:Using the United States ABMP noninvasive portable ambulatory blood
pressure monitoring on the patients with essential hypertension blood pressure circadian
rhythm changes of cardiac ultrasound examination, application in hypertensive patients
with left ventricular diastolic function in patients with essential hypertension, circadian
rhythm of blood pressure and left ventricular diastolic dysfunction of the relationship.
Methods: On 70 cases of hypertension patients by ambulatory blood pressure
monitoring, monitoring of the subjects of the circadian rhythm of blood pressure, and on
the basis of the circadian rhythm of blood pressure in patients with hypertension were
grouped. On 70 cases of hypertension patients and 40 healthy people undergoing cardiac
ultrasound examination, with mitral valve flow spectrum and mitral Doppler tissue
imaging measurements in subjects with indicators, assessment of left ventricular diastolic
function. Comparison of day-night rhythm of blood pressure in eac
