There is a scarcity of data on clinical outcomes after intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with multivessel disease and diabetes. The Optimal Intravascular Ultrasound Guided Complex Percutaneous Coronary Intervention study multivessel cohort was a prospective, multicenter, single-arm trial enrolling 1,021 patients who underwent multivessel PCI, including left anterior descending coronary artery using IVUS, aiming to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared the clinical outcomes between those patients with and without diabetes. The primary end point was a composite of death, myocardial infarction, stroke, or any coronary revascularization. There were 560 patients (54.8%) with diabetes and 461 patients (45.2%) without diabetes. The mean age was not different between the 2 groups (70.9 ± 9.7 vs 71.7 ± 10.4 years, p = 0.17). Patients with diabetes more often had chronic kidney disease and complex coronary artery disease, as indicated by the greater total number of stents and longer total stent length. The rate of meeting the OPTIVUS criteria was not different between the 2 groups (61.2% vs 60.7%, p = 0.83). The cumulative 1-year incidence of the primary end point was not different between the 2 groups (10.8% vs 9.8%, log-rank p = 0.65). After adjusting for confounders, the risk of diabetes relative to nondiabetes remained insignificant for the primary end point (hazard ratio 0.97, 95% confidence interval 0.65 to 1.44, p = 0.88). In conclusion, in patients who underwent multivessel IVUS-guided PCI and were managed with contemporary clinical practice, patients with diabetes had similar 1-year outcomes to patients without diabetes.
