Patients in the high\u2010SYNTAX\u20101\u2010group (score\u2009&gt;\u200932) were more often in an acute condition compared to low\u2010SYNTAX\u20102\u2010group (score\u2009\u2264\u200932) including acute myocardial infarction (76.2% vs. 57.4%, <jats:italic>p<\/jats:italic> =\u2009.024), cardiogenic shock (48.2% vs. 14.8%, <jats:italic>p<\/jats:italic> =\u2009.001), or need for mechanical support (36.1% vs. 11.1%, <jats:italic>p<\/jats:italic> =\u2009.001). Survival was predicted by the acute condition including cardiogenic shock (OR 0.06 and 0.05) and myocardial infarction (OR 0.03 and 0.34) in both groups. Performance of the SYNTAX\u20101\u2010score was limited in our patient collective in both groups (c\u2010index 0.65 vs. 0.63) while SYNTAX\u20102\u2010PCI\u2010score performed better (c\u2010index 0.67 vs. 0.67).

Prognosis was best predicted by the acute condition and the EuroScore II. These data suggest that therapy in unstable patients should be guided by clinical condition over the anatomical
