2%硝酸甘油(NTG)软膏的皮肤贴敷应用,长期以来认为是延长 NTG 使用的有效方法。但是每日需多次应用却限制了它的用途。最近试制成功皮肤贴敷改进措施能延长 NTG 24小时的连续应用。本文评价 NTG 贴敷对劳力型心绞痛者运动耐量的影响。方法:14例(13例男性与1例女性)年龄为50～70岁的典型劳力型心绞痛患者,冠状血管造影(n=6)、铊运动试验(n=5)、超声心动图运动试验(n=5)均提示有可逆行节段性灌注或运动时收缩异常。整个试验是在 Godart 自行车测力计上进行, The application of a 2% nitroglycerin (NTG) ointment to the skin has long been considered an effective method of prolonging the use of NTG. However, multiple applications daily limit its usefulness. The recent successful trial of skin patch improvement can prolong NTG 24 hours of continuous application. This article evaluates the effect of NTG sticking on exercise tolerance in patients with exertional angina. Methods: Coronary angiography (n = 6), thallium treadmill test (n = 5), echocardiographic exercise test (n = 5), and treadmill test were performed in 14 patients (13 males and 1 females) n = 5) were all suggestive of reversible segmental perfusion or abnormal contraction during exercise. The whole experiment was carried out on Godart bicycle dynamometer,
