China ST-elevation myocardial infarction Care Project data elements
| Category | Example elements |
| Patient baseline information | Demographics (age, sex, ethnicity, region, occupation, marriage status and medical insurance type). Risk factors (smoking status, BMI, hypertension, diabetes, dyslipidaemia, chronic kidney disease, peripheral artery disease, MI history, stroke history and prior revascularisation). Clinical presentation (blood pressure, heart rate and cardiac function classification). |
| Prehospital information | Patient (symptoms, symptom-onset time and hospital approaching method). EMS (response time, transfer process, first medical contact time, first ECG time, ECG transmission ratio and bypass ED ratio). Non-PCI hospital (hospital approaching method, first medical contact time, admission time, first ECG time, diagnosis time, consent time, reperfusion and other treatment, DI-DO time and transfer process). |
| PCI hospital information | Reperfusion (methods, indication and contraindication, and non-reperfusion reasons). Treatment delay (hospital approaching method, first medical contact time, bypass ED ratio, admission time, first ECG time, catheter lab ready time, consent time, D2B, D2N, FMC2B, FMC2N, total ischaemic time and reasons of delay). PCI procedures (operative route, coronary angiography results, aspiration, culprit vessels, stent and elective PCI). Thrombolytic procedures (thrombolytic agent, dose and outcome). Medications (loading dose DAPT and statin, antiplatelets, β-blockers, statin, ACEI/ARB, GP IIb/IIIa inhibitor and anticoagulant with dose and contraindication information). Laboratory results (troponin, CK-MB, creatinine, HbA1c, fasting glucose, BNP or NT-proBNP, lipid profiles, ECG and UCG). Discharge (diagnosis, in-hospital duration, expense and medications). Outcomes (death, non-fatal reinfarction, non-fatal stroke, revascularisation, mechanical complication and bleeding). |
| Follow-up and management | Presentation status (symptom, cardiac function classification, blood pressure, heart rate and follow-up on-time ratio). Laboratory results (lipid profiles, glucose traits, HbA1c, creatinine, haemoglobin, BNP or NT-proBNP, ECG and UCG). Medications (antiplatelets, β-blockers, statin and ACEI/ARB). Risk factor control rate (blood pressure, lipid, glucose and smoking cessation). Outcomes (death, non-fatal reinfarction, non- fatal stroke, revascularisation, rehospitalisation due to unstable angina pectoris, heart failure or other cardiovascular reasons and bleeding). |
