Abstract:

Objective To observe the clinical efficacy of Xin’ anning Nasal Drop (XAND, 心安宁滴鼻剂) in treating coronary heart disease with unstable angina pectoris (CHD-UAP). Methods Sixty patients with CHD-UAP were assigned, according to the randomizing number table, to two groups, the control group treated with conventional Western medicine, and the treated group treated with conventional Western medicine plus XAND. The clinical efficacy and the changes of S-T segment in resting EKG and total ischemia burden (TIB) in 24-h dynamic EKG were observed. Results The clinical efficacy, including the effect of angina alleviation, its initiation, and the effect of TCM syndrome score reduction, were significantly superior in the treated group to those in the control group (P<0.05 or P<0.01). The degree and extent of myocardial ischemia were significantly improved in both groups (P<0.01), but the improvement in the treated group was better than that in the control group (P<0.05). Moreover, it was worth mentioning that the immediate effect in the treated group was better than that in the control group, and the reduction of TIB, the improvement in heart rate and myocardial oxygen consumption (immediately after the first administration or by the end of the therapeutic course), and systolic blood pressure after treatment in the former were all superior to those in the latter, showing significant difference (P<0.05 or P<0.01). Conclusion XAND has a quick effect in alleviating angina in patients with CHD-UAP, and it is worthy of furtherstudies and spreading in clinical practice.
