本研究目的是确定不稳定型心绞痛患者冠状循环血浆血小板衍生生长因子(PDGF)水平是否升高。方法对象是43例均经冠脉造影检查者。分成三组。A组14例不稳定型心绞痛,在导管检查一个月内心绞痛恶化和/或出现休息时心绞痛,但无心肌坏死的酶学证据。B组15例稳定型劳力性心绞痛。C组15例有非典型胸痛而平板试验无缺血表现。三组的年龄、性别、糖尿病、高血压和吸烟史方面匹配。A、B两组的药物治疗相仿。在每例患者
The aim of this study was to determine whether elevated plasma levels of platelet-derived growth factor (PDGF) in patients with unstable angina. Methods Subjects were 43 cases were confirmed by coronary angiography. Divided into three groups. A group of 14 cases of unstable angina pectoris, angina pectoris within one month of catheterization and / or angina at rest, but without enzymatic evidence of myocardial necrosis. Group B, 15 cases of stable angina pectoris. Fifteen patients in group C had atypical chest pain but no evidence of ischemia in the plate test. The three groups matched for age, gender, diabetes, hypertension, and smoking history. A, B two groups of similar drug treatment. In every patient
