Material and methods
Patients
A total of 352 patients were included in the study and
divided into two groups. The first group consisted of 217
patients admitted between January 2012 and December
2012 with stable or unstable angina and treated with
percutaneous coronary intervention (PCI group). The second
group consisted of 135 patients admitted between
September 2006 and December 2012 and treated with
peripheral interventions (in the legs, carotid artery, renal
artery, and subclavian artery) (PTA group). Single-vessel
coronary disease was diagnosed when ≥ 70% stenosis
in one of the native coronary arteries was present. Multiple-
vessel coronary disease was diagnosed when ≥ 70%
stenosis were found in at least two native coronary arteries.
Peripheral interventions were performed in symptomatic
patients with critical stenosis. All patients in
both groups had already undergone coronary/peripheral
angiogram before current hospitalisation.
