Which elderly patients with cardiogenic shock should be treated with percutaneous coronary intervention?

75 years were enrolled, and of the 28 patients who were randomized to undergo emergency revascularization, only 12 underwent percutaneous coronary intervention (PCI). Because of these small numbers, no conclusions could be drawn about the possible benefit of emergency PCI in this age group. [...]the under-representation of elderly patients in clinical trials means that there is currently a paucity of data (especially with mortality end points) on which to base recommendations for their treatment. Because of the high mortality rate in this age group, it is important that future trials are adequately powered to address these issues.
