- Abstract
Background Complex percutaneous coronary intervention (PCI) is increasingly performed in older adults (age ≥75 years) with stable ischemic heart disease. However, little is known about clinical outcomes. Methods and Results We derived a cohort of older adults undergoing elective PCI for stable ischemic heart disease across a large health system. We compared 12-month event-free survival (freedom from all-cause death, nonfatal myocardial infarction, stroke, and major bleeding), all-cause death, target lesion revascularization, and bleeding events for patients receiving complex versus noncomplex PCI and derived risk estimates with Cox regression models. We included 513 patients (mean age, 81±5 years). Patients receiving complex PCI versus noncomplex PCI did not significantly differ across a host of clinical characteristics including cardiovascular disease features, noncardiac comorbidities, guideline-directed medical therapy use, and frailty. Patients receiving complex PCI versus noncomplex PCI experienced worse event-free survival (80.4% versus 86.8%), which was not significant in adjusted analyses (hazard ratio [HR], 1.38 [95% CI, 0.88-2.16]). All-cause death at 1 year for patients undergoing complex PCI was nearly double that seen for patients receiving noncomplex PCI (10.2% versus 5.9%), and the risk was significant in models adjusted for clinical characteristics (HR, 1.97 [95% CI, 1.02-3.79]). Target lesion revascularization risk was lower for patients receiving complex PCI (2.2% versus 3.5%, adjusted HR), but bleeding events were not statistically different between groups (25.3% versus 20.5%; P =0.19). Conclusions Complex PCI in older adults with stable ischemic heart disease was associated with lower risk of target lesion revascularization but higher all-cause death compared with noncomplex PCI.
