Kalpa De Silva, M.B.B.S., of King's College London, and colleagues conducted a retrospective study involving 660 patients who underwent PCI with previous left ventricular function assessment. Of these, 221 patients had previously undergone coronary artery bypass grafting (CABG). Blinded observers calculated the BCIS-JS before (BCIS-JSPRE) and after (BCIS-JSPOST) PCI, and the extent of revascularization was quantified using the revascularization index (RI; RI = [BCIS-JSPRE − BCIS-JSPOST]/BCIS-JSPRE).
The researchers found that both BCIS-JSPRE and BCISJSPOST scores were directly related to all-cause mortality (hazard ratios [HRs], 2.96 and 4.02, respectively). Other independent predictors of mortality included having a RI of less than 0.67 (HR, 1.99), left ventricular dysfunction (HR, 2.03), and renal impairment (HR, 3.75), in multivariate analysis.
