A patient with diabetes mellitus and coronary artery disease presented with recurring episodes of worsening angina not associated with angiographic changes. Correlation with blood sugars demonstrated that angina would occur during episodes of hyperglycemia. During cardiac catheterization, coronary vascular responses including coronary flow reserve and responses to atrial pacing were measured with a Doppler flow wire before and following a glucose challenge. Coronary microvascular responses were impaired by hyperglycemia.
一位患有糖尿病和冠状动脉疾病的患者出现反复发作的心绞痛，且心绞痛加重与血管造影变化无关。血糖相关性研究表明，心绞痛会在高血糖发作时出现。在心脏导管插入术中，在葡萄糖激发试验前后，使用多普勒血流导线测量包括冠状动脉血流储备和对心房起搏的反应在内的冠状动脉血管反应。高血糖会损害冠状动脉微血管反应。
