BACKGROUND: Previous studies have demonstrated improved outcomes with an early invasive strategy in patients with unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI). However, there are limited data for patients ≥80 years of age in these studies. METHODS: We used the 2003-2010 Nationwide Inpatient Sample databases to identify all patients ≥80 years of age (octogenarians) with UA/NSTEMI. Multivariable logistic regression was used to compare in-hospital outcomes in octogenarians with UA/NSTEMI undergoing early invasive (coronary angiography within 48 hours of admission, with or without revascularization) versus initial conservative treatment. RESULTS: Among 968,542 octogenarians with UA/NSTEMI, 806,902 (83.3%) were managed using an initial conservative approach and 161,640 (16.7%) using an early invasive strategy. Patients in the early invasive group were more likely to be younger, men, white, and had a higher prevalence of smoking, dyslipidemia, obesity, hypertension, known coronary artery disease, carotid artery disease, and peripheral vascular disease. In-hospital mortality was significantly lower in octogenarians in the early invasive group (adjusted odds ratio [OR] 0.76; 95% confidence interval [CI], 0.74-0.78). Early invasive strategy was associated with lower rates of acute ischemic stroke (adjusted OR 0.63; 95% CI, 0.60-0.66), intracranial hemorrhage (adjusted OR 0.60; 95% CI, 0.510.70), gastrointestinal bleeding (adjusted OR 0.63; 95% CI, 0.60-0.65), and shorter average length of stay (5.3 vs 5.8 days, P <.001), but higher cardiogenic shock (adjusted OR 2.14; 95% CI, 2.06-2.23) and total hospital cost (23,584 vs 13,278 USD). CONCLUSION: Compared with an initial conservative approach, an early invasive strategy in octogenarians with UA/NSTEMI was associated with lower in-hospital mortality, acute ischemic stroke, intracranial hemorrhage, gastrointestinal bleeding, and shorter length of stay, but higher cardiogenic shock and total hospital cost.
