This study aimed to assess the effect of St. John＇s wort extract （SWE） on depressive disorder in elderly patients with unstable angina pectoris. Altogether 170 patients who met the set criteria were enrolled in this prospective study. They were randomly divided into SWE group （44 patients）, Deanxit group （44）, psychotherapy group （42）, and control group （40）. The effectiveness of SWE was evaluated by reduced percentage of Hamilton depression （HAMD） scale and reduced frequency of angina pectoris attack, which were measured before and at 12 weeks after the treatment with SWE. The reduced percentages of HAMD scale were 79.5%, 56.8% and 57.1% in the SWE, Deanxit and psychotherapy groups, respectively. Compared with the control, the three groups had significant differences in the percentages （P〈0.001）. The improvement after the treatment was more significant in the SWE group than in the Deanxit or psychotherapy group （P〈0,05）. The improvement of angina pectoris evaluated by the Canadian Cardiac Society Classification was significantly better in the treatment groups （88.7%, 65.9%, 57.1%） than in the control group, and it was marked in the SWE group （P〈0.001）. Angina pectoris attack, its frequencies, durations and electrocardiographic changes were significantly improved in the treatment groups than in the control group （F=6.05, 4.58, 5.12, P〈0.01）. They are markedly improved in the SWE group （P〈0.05）. SWE can improve depressive symptoms more significantly in elderly patients with unstable angina pectoris than Deanxit or psychotherapy, proving that SWE contributes to better treatment of angina attack as well.展开更多
