PCI in Beijing Friendship Hospital

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to discover the potential risk factors related percutaneous coronary intervention. It aims to stratify the risk of PCI patients and discover the prognostic value of these risk fators.

Detailed Description
-----------------
Coronary heart disease is the main cause of death worldwide. Ischemic heart disease is the most common cause of death. Percutaneous coronary intervention (PCI) is a very effective treatment for coronary heart disease, which can alleviate myocardial ischemia and reduce the mortality of patients with acute myocardial infarction. It is an important measure to treat coronary heart disease at present. However, the study found that the incidence of major adverse cardiac and cerebrovascular event (MACCE) after PCI was more than 10%, which could reach 20-30% in elderly patients. Therefore, the purpose of this study is to investigate the risk factors related to PCI and to intervene or change the treatment strategy as early as possible. Risk stratification was performed in these patients for improving the quality of life of patients, reducing medical costs, and improving the life expectancy of patients. Patients with PCI in Beijing friendship hospital are enrolled.The primary outcome is MACCE and all-cause mortality.
