Hospital readmission rate following percutaneous coronary interventions (PCI) or coronary angiographies (CAG) is a main indicator of quality of care and addresses economic issues. The aim of this study is to quantify the frequency and analyse the types of rehospitalizations and repeat revascularizations during one year after a PCI or a CAG. This information is needed to organize the health care pathway and to identify preventable rehospitalizations.

Inclusion Criteria:

• Patients included in ACIRA Registry : All volunteer adults (≥ 18 years) and French resident patients who underwent PCI and CAG in the interventional cardiology hospitals in the Aquitaine region (France),
• Initial PCI or CAG performed from January 1, 2012 to December 31, 2013,
• Initial PCI or CAG performed in nine interventional cardiology hospitals in the Aquitaine region (France).

Exclusion Criteria:

• Patients who declined to take part of ACIRA Registry,
• Patients resident outside the Aquitaine region (France),
• Patients who died during the initial hospital stay,
• Patients hospitalized for a PCI or a CAG the month preceding the initial procedure including in the ACIRA-Rehosp study.

All volunteer adults (≥ 18 years) and French resident patients who underwent PCI and CAG in nine interventional cardiology hospitals in the Aquitaine region (France), from January 1, 2012 to December 31, 2013.
