BackgroundHybrid coronary revascularization (HCR) involves minimally invasive left internal mammary artery to left anterior descending coronary artery grafting combined with percutaneous coronary intervention (PCI) of non-left anterior descending vessels. The safety and efficacy of HCR among diabetic patients are unknown.MethodsPatients with diabetes were included who underwent HCR at a US academic center between October 2003 and September 2013. These patients were matched 1:5 to similar patients treated with coronary artery bypass grafting (CABG) using a propensity score (PS)-matching algorithm. Conditional logistic regression and Cox regression stratified on matched pairs were performed to evaluate the association between HCR and inhospital complications, a composite measure of 30-day mortality, myocardial infarction and stroke, and up to 3-year all-cause mortality.ResultsOf 618 patients (HCR = 103; CABG = 515) in the PS-matched cohort, the 30-day composite of death, MI, or stroke after HCR and CABG was 4.9% and 3.9% (odds ratio: 1.25; 95% CI [0.47-3.33]; P = .66). Compared with CABG, HCR also had similar need for reoperation (7.6% versus 6.3%; P = .60) and renal failure (4.2% versus 4.9%; P = .76) but required less blood products (31.4% versus. 65.8%; P < .0001), lower chest tube drainage (655 mL [412-916] versus 898 mL [664-1240]; P < .0001), and shorter length of stay (<5 days: 48.3% versus 25.3%; P < .0001). Over a 3-year follow-up period, mortality was similar after HCR and CABG (12.3% versus 14.9%, hazard ratio: 0.94, 95% CI [0.47-1.88]; P = .86).ConclusionAmong diabetic patients, the use of HCR appears to be safe and has similar longitudinal outcomes but is associated with less blood product usage and faster recovery than conventional CABG surgery.Copyright © 2014 Mosby, Inc.
