本文报告12名劳累性心绞痛病人,用随机单盲法比较青心酮和安慰剂对运动耐量和左心室功能的影响。在次极量踏车运动前后记录标测心电图、STI 和心阻抗微分图。结果:与安慰剂比较,青心酮使平均运动时间增加3.7分(P<0.01);标测心电图∑ST 和 NST明显减少(P<0.01);TPR 轻度降低(P<0.05)。提示:青心酮能显著改善心绞痛病人的运动耐量并降低其心肌耗氧。
In this paper, we report 12 patients with exertional angina pectoris who were randomized to single-blind versus placebo for exercise tolerance and left ventricular function. Before and after the second extreme treadmill exercise recorded mapping electrocardiogram, STI and heart impedance differential diagram. Results: Compared with placebo, the CPP increased the mean exercise time by 3.7 points (P <0.01). The ΣST and NST decreased significantly (P <0.01) and the TPR decreased slightly (P <0.05). Tip: Qingxin ketone can significantly improve angina patients exercise tolerance and reduce myocardial oxygen consumption.
