The Chinese STEMI PPCI Registry (CSPR)

The Chinese ST-Segment Elevation Myocardial Infarction Primary Percutaneous Coronary Intervention Registry

The purpose of this study is to develop a risk score to predict the risks of in-hospital major adverse cardiac events in ST-segment elevation myocardial infarction patients treated by primary percutaneous coronary intervention.

The CSPR trial is an observational clinical trial to derive and validate a readily useable risk score to identify patients at high risk of in-hospital major adverse cardiac events in 5594 patients presenting with a ST-segment elevation myocardial infarction and treated by primary percutaneous coronary intervention.

Inclusion Criteria:

1. Age≥18
2. ST-segment elevation myocardial infarction was defined according to the universal definition of myocardial infarction
3. STEMI treated by pPCI

Exclusion Criteria:

1. Patient with heart failure in admission
2. STEMI with symptom-onset-to-balloon time>24h
3. pPCI was not successful or only underwent coronary angiography
4. Killip class ≥II in admission
