Abstract
Objective
To observe the effect of Yiqi Yangyin Decoction (益气养阴方, YQYYD) on the quality of life (QOL) of patients with unstable angina pectoris (UAP).
Methods
A total of 108 patients with UAP of qi-yin deficiency syndrome confirmed by coronary angiography were enrolled and assigned to the treated group (treated with YQYYD and conventional therapy of Western medicine) and the control group (treated with conventional therapy of Western medicine), by the use of the PROC PLAN of the SAS 6.12 software, in a prospective, randomized, controlled design. The clinical total effective rate, symptom score, QOL scale [Seattle Angina Questionnaire (SAQ)] and incidence of important clinical events were defined as the observation indices to evaluate the interventional effect of YQYYD on the QOL of patients with UAP of the qi-yin deficiency syndrome.
Results
During the study, three cases dropped out in the treated group, one case dropped out in the control group, and 104 cases, including 51 cases in the treatment group and 53 cases in the control group, finished the trial. After four weeks of treatment, the total clinical effective rates in the treated group and the control group were 80.4% and 75.5% respectively, and there was no obvious difference between them (P>0.05). However, the symptom score of the treated group (9.31±2.02) was significantly lesser than that of the control group (11.62±3.04, P<0.05), and the total score of the QOL scale of the treated group (68.76±5.74) was significantly higher than that of the control group (61.06±3.31, P<0.01). Among those in the treated group physical limitation, angina stability, angina frequency, and treatment satisfaction were significantly ameliorated when compared with the control group after treatment (P<0.05, P<0.01). The incidence of important clinical events in the treated group (3.9%) was lower than that in the control group (5.7%) during the 8-month follow-up period, but the difference was insignificant (P>0.05).
Conclusion
YQYYD could improve the clinical symptoms of patients with UAP of qi-yin deficiency syndrome and greatly improve their QOL.
