β乐克治疗不稳定型心绞痛疗效观察

不稳定型心绞痛是介于稳定型心绞痛和急性心肌梗死之间的临床状态，是发生心脏事件的高危对象，故积极地治疗不稳定型心绞痛，对改善病人的预后有重要作用。近年来有报道用β乐克结合硝酸酯类扩冠药物治疗不稳定型心绞痛，能较好地缓解心绞痛症状。现将我院白2003年1月-2004年6月问共收治不稳定心绞痛66例采用β乐克结合常规药物治疗的临床效果总结如下。

升主动脉成形术中期效果分析

Objective Reduction ascending aortoplasty is an alternative procdure to the replacement of the ascending aorts in case of ascending aorta dilation. However,its applicabikity is still under debate.This retrospective study was designed to evaluuate the midterm follow-up of unsupported ascending reduction aortoplasty for of the ascending aorta in petients with aortic valve dis- ease.Methods From October ,1996 to April,2007, a total of 54 patients with aortic valve disease and dilatation of the ascending aorta underwent unsupported reduction aortoplasty in combination with aortic valve replacement at our institution The diameter of the ascending aorta was measyred before and early after sugery and then later between 13 and 96 menths [mean (23 ±16)months] posto- perativeiy using echocardiography.Results Two patients were dead with thean overall perioperative mortality rate was of 3.7%. The reduction aortoplasty decreased the diameter of the aorta from (45.77±6.02) mm p～eope～afive]y to (34.67 ～4.81) mm early after surgery (P<0.01). During follow-up, the diameter d aorta increased from (34.67±4.81) mm early after surgery to (37.65± 6.35) mm after a mean follow-up of (23±16) months (P<0.01), including the diameters are greater than > 45 mm within 5 pa- tients. Aortic stenosis and an early postoperative diameter greater than 40 mm m'e independent risk factors for redilatation. Conchusion Because of the unsatisfied midterm follow-up redilation of unsupported reduction aortoplasty for dilation of the ascending aorta with aortic valve disease, this group of patients needs continued intimate fallow-up or even reoperation. The patients of stenosis is the surtable indication for RAA, and it is necessary to reduce the diameter of aorta to be lees than 40 mm to prevent redilation.

心脏按压有效的指征是什么？

答：心脏按压有效的指征有七个：（1）按压时能摸到大动脉搏动，收缩压大于8．0kPa；（2）病人面色、口唇、甲床及皮肤色泽由灰白转红润；（3）散大的瞳孔又缩小；（4）有呼吸改善或出现自主呼吸；（5）昏迷变浅或出现反射挣扎；（6）有尿液排出；（7）心电图形改善。只要前两项指标出现，就应坚持按压心脏。
