Published data about nonagenarians with acute coronary syndrome (ACS) were mainly descriptive and limited by small sample sizes and unadjusted outcomes. We aim to describe the characteristics, management, and the impact of an invasive strategy on major adverse events in elderly patients hospitalized with ACS with focus on the nonagerians. Methods and Results We analyzed data collected as part of the AMI‐OPTIMA study, a cluster‐randomized study of knowledge translation intervention versus usual care on optimal discharge medications in patients admitted with ACS at 24 Canadian hospitals. To determine whether an invasive strategy improved outcomes in the elderly, we used inverse probability weighting to adjust for confounders between patients who underwent invasive versus conservative strategies. Of 4,569 consecutive patients: 2,395 (52%) were 〈 70 years old, 1,031 (23%) were septuagenarians, 941 (21%) were octogenarians, and 202 (4.4%) were nonagenarians. An invasive strategy was associated with reduced in‐hospital all‐cause mortality in all age groups: 1.1% versus 3.8% in patients 〈 70 years old ( P 〈 0.001), 2.9% versus 7.4% in septuagenarians ( P 〈 0.001), 5.1% versus 14.7% in octogenarians ( P 〈 0.001), and 12.0% versus 25.1% in nonagenarians ( P = 0.001). An invasive strategy was also associated with higher thrombolysis in myocardial infarction major bleeds in the nonagenarians (9.0% vs. 2.0%; P = 0.003). Conclusions The reduction in in‐hospital mortality associated with an invasive strategy in elderly and nonagenarians presented with ACS is generating hypothesis and merits further studies to confirm these benefits and to guide clinicians in the management of these high‐risk patients.
