Coronary Angiography
The severity of CAD was assessed by two experienced cardiologists using
the SYNTAX score12 . They were blinded to the
patients’ clinical characteristics. The SYNTAX-1 score was calculated
using dedicated software (version 2.11) that integrates the number of
lesions with their specific weighting factors, based on the amount of
myocardium distal and the morphologic features of each lesion.
We isolated and defined two subgroups within our study population: group
1 included patients with nonsignificant CAD (<50% diameter
stenosis); group 2 included patients with significant CAD (≥50%
diameter stenosis) (see Figure 1).
