Various approaches for peforming an outpatient coronary angiography

To study the safety and clinical efficacy of an outpatient coronary angiography in various groups of patients according to a 6-year experience of the laboratory of endovascular diagnostic and treatment methods in the outpatient setting of the NMRC of Cardiology.

2166 patients which underwent an outpatient coronary agiography from March 2009 to December 2014 were included. The success criteria was the successful completion of the procedure without the occurrence of major cardiovascular complications (death, transmural myocardial infarction; acute cerebrovascular accident, emergency cardiac surgery).

All 2166 patients included in the study were divided into 2 groups: Group 1 - 1316 patients who were discharged home several hours after the study; Group 2 - 850 patients directed from hospitals without catheterization laboratories with the same-day discharge back to the referring hospital. From a clinical point of view, in the second group there were more severe patients. However, the study was successfully completed in all patients in both groups. There were no major adverse cardiovascular complications during the procedure and within 24 hours. In the 1st group, unplanned hospitalization occurred in 2.1% of cases, the cause of which in 93% of cases was the detection during angiography of a critical lesion ≥70% of the left main coronary artery.

In our work, the incidence of complications was extremely low and not significantly different in both groups of patients. This is due to the fact that in patients with a more severe symptoms underwent a preliminary stabilization of their clinical condition. The introduction of outpatient technologies will optimize the invasive diagnostics and reduce the costs associated with hospitalization.
