They were also significantly more likely to have a patient-oriented composite outcome, defined as all-cause death, any myocardial infarction, or any revascularization (HR, 1.44; 95% CI, 1.28-1.63; P < .001).
There was also a significantly higher risk for cardiac death in HIR than in non-HIR patients (HR, 1.95; 95% CI, 1.16-3.29; P = .012).
However, there was no significant association between HIR status and clinically relevant bleeding (HR, 0.84; 95% CI, 0.66-1.06; P = .143).
When the researchers looked at individual ischemic risk features, they found that, on fully adjusted analyses, only two were independent predictors of target vessel failure and the patient-oriented composite outcome.
Having at least three stents implanted was significantly associated with target vessel failure (HR, 1.36; 95% CI, 1.02-1.80; P = .038), and borderline significantly associated with the patient oriented composite outcome (HR, 1.23; 95% CI, 1.00-1.53; P = .056).
Diffuse multivessel disease, especially in diabetic patients, was significantly associated with both target vessel failure (HR, 1.24; 95% CI, 1.02-1.51; P = .035) and with the patient-oriented composite outcome (HR, 1.20; 95% CI, 1.04-1.39; P = .012).
Neither risk feature was significantly associated with clinically relevant bleeding, Dr. Wang noted.
Stratifying the patients by HBR status, the team found that rates of target vessel failure, the patient-oriented composite outcome, cardiac death, myocardial infarction, and definite/probable stent thrombosis were higher in patients with both HIR and HBR than those with neither HIR nor HBR (P < .001).
Further stratifying patients by PRECISE-ADAPT scores – 10 or less indicating very low risk, 11-17 indicating low risk, 18-24 indicating moderate risk, and at least 25 indicating high risk – showed that HIR features had a consistent effect on ischemic and bleeding outcomes, regardless of bleeding risk.
