2.2 Data analysis
Demographic and clinical characteristics of the patients were analyzed.
The diagnosis at admission was divided in three categories: Stable
Angina, Unstable Angina and Myocardial Infarction (NSTEMI/evolved
STEMI). The angiographic characteristics were expressed as the number of
vessels with significant stenoses as well as the SYNTAX score [2].
The perioperative risk was defined by the STS score [7].
The primary outcomes for this study were the proportion of patients
referred to each revascularization modality in the HT and No HT groups
and the time to revascularization from the initial diagnostic coronary
angiography.
