Jackson M, et al. - Researchers evaluated the link between diabetes mellitus (DM) and left ventricular (LV) function on outcomes following percutaneous coronary intervention (PCI) by analyzing all PCI procedures performed between 2006 and 2013 with LV function and diabetic status recorded in the BCIS-NICOR database. In order to obtain adjusted estimates of clinical outcome by LV function and DM, including DM sub-type, multivariable logistic regression was used. DM was found to be related to increased 30-day mortality for all grades of LV function. In those with normal LV function, DM was seen to have the strongest prognostic impact, which was less evident in patients with severe LV systolic dysfunction.
