Continuous variables are expressed as the mean±SE or median and IQR with statistical comparisons between patients with ACS and suspected stable angina performed using the Student t test or Mann–Whitney, where appropriate. Categorical variables are expressed as the absolute number of cases and the group proportion (%) with statistical comparisons performed using a χ2 test. Statistical comparisons were performed using the Student t test, Mann-Whitney test or χ2 analysis where appropriate.
LAD, left anterior descending; LCx, left circumflex; PCI, percutaneous coronary intervention; RCA, right coronary artery; SVG, saphenous vein graft.
