收缩压、脉压与冠状动脉病变程度相关性研究及护理

Study on relativity among systolic blood pressure,pulse pressure and degree of pathological changes of coronary artery of patients and nursing care of them

[目的]探讨冠心病病人脉压(PP)、收缩压(SBP)与冠状动脉病变程度的相关性及护理干预的临床意义。[方法]选择经冠状动脉造影证实的稳定型心绞痛病人135例,测量SBP、舒张压(DBP)、PP,比较PP、SBP与冠状动脉病变支数和狭窄评分的关系。所有观察对象入院后、冠状动脉造影术前,均由护士进行健康教育、术后指导及出院前的依从性教育,观察术前、术中及术后系统的护理干预效果。[结果]PP≥60mmHg的病人冠状动脉狭窄程度及病变支数显著高于PP<60mmHg的病人(P<0.01),SBP、PP随冠状动脉狭窄支数和狭窄评分的增加而逐渐增高,DBP则随冠状动脉狭窄支数和狭窄评分的增加而逐渐降低(P<0.01)。[结论]PP越大,SBP越高,冠状动脉病变程度越重,术前、术中及术后系统的护理干预有非常重要的意义。

Objective：To probe into the relativity among pulse presure （PP）,systolic blood presure （SBP） and degree of pathological changes of coronary artery of coronary heart disease patients and clinical significance of nursing intervention.Methods：A total of 135 patients with stable angina pectoris verified by coronary arteriography were selected.Systolic blood pressure,diastolic blood pressure （DBP） and pulse pressure of all cases had been measured.Relations among PP,SBP,branches of coronary artery with pathological changes and stenosis scores of all cases were compared.All cases were carried out health edication,postoperative guidance and education on compliance before discharge by nurses after admission and before accepting coronary arteriography.And effect of systematic nursing intervention of all cases before,during and after the operation of all cases were observed.Results：Both the degree of stenosis of coronary artery and branches of pathological changes of patients with PP≥60 mmHg were significantly higher than that of those with PP〈60mmHg （P〈0.01）.SBP and PP of patients increased as their numbers of branches of coronary artery stenosis increasing and stenosis scores going up.However,distolic blood pressure of patients was inversely decreased with numbers of branches of coronary artery stenosis increasing and going up of stenosis scores （P〈0.01）.Conlusion：The higher of the PP and SBP of patients,the more severe of coronary artery pathological changes of them.It has very important significance to carry out systematic nursing intervention for coronary artery heart disease patients before,during and after operation.
