Background: The aim of this study was to test a relational database including clinical
data and imaging findings in a large cohort of subjects with suspected or known Coronary Artery
Disease (CAD) undergoing stress single-photon emission computed tomography (SPECT) myocardial perfusion imaging.
Methods: We developed a relational database including clinical and imaging data of 7995 subjects
with suspected or known CAD. The software system was implemented by PostgreSQL 9.2, an open
source object-relational database, and managed from remote by pgAdmin III. Data were arranged according to a logic of aggregation and stored in a schema with twelve tables. Statistical software was
connected to the database directly downloading data from server to local personal computer.
Results: There was no problem or anomaly for database implementation and user connections to
the database. The epidemiological analysis performed on data stored in the database demonstrated
abnormal SPECT findings in 46% of male subjects and 19% of female subjects. Imaging findings
suggest that the use of SPECT imaging in our laboratory is appropriate.
Conclusion: The development of a relational database provides a free software tool for the storage
and management of data in line with the current standard.
