The Stenting versus Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) study, is the first stroke prevention trial to compare intracranial stenting with medical therapy and incorporate intensive medical management to the study design. Patients in the study were ages 30 to 80 years old and had experienced a recent transient ischemic attack or another type of non-disabling stroke. All patients participated in a lifestyle modification program focused on quitting smoking, increasing exercise, and controlling diabetes and cholesterol.
The results showed that patients at high risk for a second stroke had a lower risk of stroke and death when treated with aggressive medical therapy than patients who received a brain stent in addition to aggressive medical therapy. The trial seems to indicate that stents are detrimental to patients at high risk of stroke. It was hypothesized by the trial investigators that those with stents would decrease their risk of death.
