Categorical variables expressed as frequency (%). VD, vessel disease; LMS, left main stenosis; CAD, coronary artery disease; CAG, coronary angiography; PCI, percutaneous coronary intervention; CABG, coronary artery bypass graft; P2Y12, antiplatelet inhibitors. aRedeemed prescriptions of concomitant medication: from 365 days before until 7 days after discharge. Differences between the groups were found using chi-square test.
