Blood pressure lowering as secondary prevention of stroke or transient ischaemic attack

Raised blood pressure is the main reversible risk factor for first and recurrent stroke. Lowering blood pressure reduces the risk of recurrent strokes and cardiovascular events by about 30% per year. Even patients with initial blood pressure in the normal range benefit.

In all patients, after the acute phase of stroke or TIA, start treatment to lower blood pressure (see drug advice). Aim for a systolic blood pressure of 120 to 130 mmHg.
