Abstract: Objective To investigate primarily the correlation between depression and prognosis in patients with coronary heart disease(CHD).Methods 246 CHD patients were divided into the depression group and non-depression group.The relation between depression and incidence of short term cardiovascular events was compared.Results The incidence of angina pectoris,ST-segment elevated myocardial infarction,non ST-segment elevated myocardial infarction,congestive heart failure,ventricular tarchycardia,ventricular fibrillation and sudden death in the near future were 75.6%,11.1%,17.8%,26.7%,12.2%,8.9% and 7.8% respectively.Depression was an independent predictive factor of all cardiovascular events.Conclusion CHD patients complicated by depression have a high incidence of cardiovascular events,and the depression is an independent predictive factor of all cardiovascular events.
