*CCP group includes patients with ACS.
†Exclusion of 19, 15, 20, 10 and 10 patients from analysis in the CCP, ACS, NCCP, NCCP-K and NCCP-U groups, respectively; in total 25 due to loss-to-follow-up and 14 due to in-hospital death.
‡NCCP group is a sum of patients with NCCP-K and NCCP-U.
ACS, acute coronary syndrome; MACE, Major adverse cardiac events defined as a combinations of the following: CABG, coronary artery bypass graft; CCP, cardiac chest pain; NCCP, non-CCP; NCCP-K, NCCP of known origin; NCCP-U, non-cardiac chest pain group of unknown origin; NSTEMI, non-STEMI; PCI, percutaneous coronary intervention; STEMI, ST-elevation myocardial infarction; UAP, unstable angina pectoris.
