Further research on implanting a baroreceptor stimulation device for resistant hypertension should document patient selection in detail and should specify the devices and techniques used, and any adjunctive therapies. It should describe the changes in blood pressure that are considered to result from baroreceptor stimulation, and those that might be caused by other factors. Outcomes should include the duration of effect of baroreceptor stimulation; device durability; and the complications of hypertension, such as myocardial infarction and stroke.
