Percutaneous coronary intervention (PCI) is one of the effective treatments for coronary heart disease (CHD), but it may cause stress events since its invasive might lead to various somatization symptoms, and then bring about anxiety, depression and other psychological disorders, thus affecting its curative effect and prognosis. In recent years, due to the extensive development of PCI treatment, such patients are not rare in clinic. It has been proved that anxiety and/or depression and CHD are reciprocal and influenced by multiple factors, but the pathophysiological mechanism is still not clear. With the continuous development of "double-heart medicine" model, clinical workers have paid more attention to the identification and diagnosis of cardiovascular disease complicated with psychological problems. The research progress of clinical diagnosis and treatment of patients with complicated anxiety and/or depression after PCI has been reviewed in present paper, thus provides a reference for the implementation of clinical work.
