Risk of Recurrent Stroke

The article by Skajaa et al.1 in this issue of Neurology® examines the risk of stroke recurrence and mortality after first and recurrent strokes among 105,397 patients with a first ischemic stroke (IS) and 13,350 patients with a first intracerebral hemorrhage (ICH) using data from the Danish Stroke Registry from 2004 to 2018. During that time, 10,650 patients had a recurrence following IS and 1,765 had one following an ICH. Notably, the sample was substantially larger than in previous studies on first-time stroke survivors and provides updated estimates of stroke recurrence and mortality in a nationwide population-based study in Denmark. These data are critical to the continued efforts to improve the effectiveness of secondary prevention strategies.
