Coronary angiography (CAG) and percutaneous coronary intervention (PCI) are invasive cardiology procedures associated with important costs and high readmission rates. The CAG and PCI pathway after patient discharge is currently unknown in France.

The aim of this study is to present the one-year readmission and in-hospital mortality results in the French Aquitaine region in 2013.

We analyzed 30-day and one-year all-cause readmission and in-hospital mortality after CAG and PCI using the ACIRA registry of 9 interventional institutions. Readmissions, in-hospital complications, cardiovascular morbidity and mortality are collected from the French medico-administrative databases, during one year after the initial procedure. A probabilistic matching method is used to merge the ACIRA and medico-administrative databases.

Overall, 62.6% of the patients were rehospitalized after one year. In-hospital readmission deaths were 3.5%, including cardiovascular-related deaths in 41.5% of the cases. Moreover, 16.8% of the patients had at least one other CAG or PCI procedure (Table 1).

ACIRA results illustrate the capacity to study the CAG and PCI pathway up to one year following the procedure. We found that in-hospital cardiovascular complications and 30-day all-cause readmission rate after PCI were particularly high. A deeper analysis to explain these high readmission rates is in progress.
