To determine whether characteristic pathologic alterations in coronary arteries are associated with impending and complicated evolving myocardial infarction, the angiographic and hemodynamic findings in 47 acute coronary patients were compared to those of 49 patients with chronic stable angina. Subtle differences in angiographic and hemodynamic alterations were found in these two groups of patients. These differences were more pronounced in patients with evolving myocardial infarction with less than--15 per cent lactate extraction. The risk of coronary arteriography was surprisingly low. Myocardial metabolic function studies demonstrating less than--15 per cent lactate extraction were considered an indication for emergency coronary arteriography in preparation for contemplated coronary bypass surgery.
为了确定冠状动脉特征性病理改变是否与即将发生的及复杂的进展性心肌梗死相关，将47例急性冠状动脉疾病患者的血管造影和血流动力学结果与49例慢性稳定型心绞痛患者的结果进行了比较。在这两组患者中发现了血管造影和血流动力学改变的细微差异。这些差异在乳酸摄取率低于15%的进展性心肌梗死患者中更为明显。冠状动脉造影的风险出奇地低。乳酸摄取率低于15%的心肌代谢功能研究被认为是进行急诊冠状动脉造影以准备择期冠状动脉搭桥手术的指征。
