Randomized Controlled Trial Clinical Trial
Trial of secondary prevention with atenolol after transient ischemic attack or nondisabling ischemic stroke. The Dutch TIA Trial Study Group.
beta-Blockers prevent vascular events in patients after myocardial infarction and lower blood pressure, the main risk factor for stroke. Hence, we assessed the effects of atenolol on the occurrence of death from vascular causes, stroke, or myocardial infarction and on blood pressure in patients after a transient ischemic attack or nondisabling ischemic stroke. ⋯ Our data neither confirm nor rule out that atenolol prevents important vascular events in patients after transient ischemic attack or nondisabling ischemic stroke, given the modest effect on blood pressure, the restrictions in patient selection, and the limited number of patient-years.
