Figure 2 Patients with predominant LV failure clinically selected to undergo left heart catheterization and coronary angiography (LH cath) had a lower mortality than those with no LH cath. Patients with no revascularization attempt had higher mortality, with the lowest mortality observed in patients selected to undergo CABG. The CABG group includes 18 patients who underwent CABG post-PTCA; these patients are not included in the PTCA group. The mortality rates for those undergoing early revascularization (within 18 h of shock diagnosis), at a time comparable to the randomized SHOCK Trial, are shown. The median times to PTCA and CABG are 2.8 and 3.9 h, respectively, for those revascularized <18 h post-shock.

*Patients with PTCA or CABG prior to shock are excluded.
