Schizophrenia is a common severe mental disorder with high rate of disability, which seriously affects patients' life.It is necessary to take long-term therapy to control symptoms or prevent recurrence. Studies have found that schizophrenia patients live on average ten to twenty-five years less than others. The main reason for high rates of mortality and disability is the high risk of cardiovascular events.There are few domestic large-scale studys on the risk of cardiovascular events in schizophrenia, thus they have not formed objective tools to assess cardiovascular risk. If this risk can be objectively assessed and predicted at an early stage, it is expected to reduce the risk of cardiovascular events and thus reduce mortality.At present, there are mature tools for assessing the risk of cardiovascular events in patients, such as Framingham, PRIMROSE, etc.The latter is the new tool for assessing cardiovascular events in patients with severe mental disorders. This study used a retrospective cohort design to collect the history of hospitalized schizophrenia patients within 2 years, collect relevant informations about cardiovascular events. The investigators validate the PRIMROSE model in China and explore the risk prediction model of cardiovascular events in schizophrenia patients.
