Clinical study of ultrasound on vascular endothelial functional status in elderly patients with newly diagnosed in ED

摘要:
目的 应用超声检测初诊中老年阴茎勃起功能障碍（ED）患者的肱动脉血管内皮功能状况。 方法 研究对象选取为2013年12月~2014年9月之间我院收治的44例初诊中老年ED患者，设为研究组，并选取同期的50例健康志愿者作为对照组，采用超声检测两组受检者在静息状态下、反应性充血后、舌下含服硝酸甘油后的肱动脉内径，计算3种状态下2组患者肱动脉内径的变化率。 结果 两组受检者的肱动脉基础内径对比无显著差异（P＞0.05），但研究组患者的反应性充血诱发的肱动脉内径变化率显著低于对照组（P＜0.05），2组受检者舌下含服硝酸甘油后再次进行诱发，结果显示2组受检者的肱动脉内径变化率无显著差异（P＞0.05）。 结论 初诊中老年ED患者的肱动脉内皮功能显著降低，采用超声检测能够有效确定患者的血管内皮功能，尽早发现无症状的心血管疾病，具有较好的临床应用价值。 Abstract:Objective To test the elderly erectile dysfunction(ED)in patients with brachial artery endothelial function status throuh ultrasonic testi. Methods A total of 44 cases of elderly ED patients admitted to our hospital between 2013.12~2014.9 were taked as test group, and 50 healthy volunteers were takedas control group. Subjects were detected using ultrasound at rest By state, after reactive hyperemia, sublingual brachial artery diameter after sublingual nitroglycerin, calculated the rate of change in three states of the two groups were brachial artery diameter. Results The rate of change in brachial artery diameter two subjects of the inner diameter of the brachial artery comparative basis no significant difference (P>0.05), but the reaction of the study group of patients with congestive induced significantly lower than the control group (P<0.05), two groups Evoked again subject sublingual nitroglycerin, two subjects showed brachial artery diameter was no significant difference in the rate of change (P>0.05). Conclusion The brachial artery endothelial function in elderly patients with ED significantly reduced the use of ultrasound to effectively determine vascular endothelial function in patients with early detection of asymptomatic cardiovascular disease, with better clinical value. -
