Table 4 Events and time to first event representing changes in management identified in HES / PEDW inpatient and outpatient data up to 12 months after the index admission in CMR vs. non CMR centres (hospitals A and B vs. hospitals C and D, respectively)

From: Feasibility of identifying important changes in care management resulting from cardiovascular magnetic resonance (CMR) using hospital episode data in patients who activate the primary percutaneous coronary intervention (PPCI) pathway

 

Number of events (%) identified in HES / PEDW up to 12 months after the index admission and number of days (median and IQR) until first event after the index admission

Patient subgroup

New diagnoses (e.g. Takotsubo, myocarditis, pericarditis, endocarditis, coronary spasm)

Changes in medication

Additional diagnostic tests (ECHO, SPECT, PET, IVUS, pressure-wire, radionuclide angiocardiography, CT angiography)

Implantation of devices (CRT or ICD)

Revascularisation (PCI or CABG) within 3 months

Cardiology outpatient appointments (median, IQR)
