Stroke is common, affecting around one in four people over the age of 45 at some time in their lives. Increasing age is a major risk factor for stroke, so the numbers of people suffering a stroke will increase with the ageing population. Primary care teams have a central role in providing effective secondary prevention, but because patients often fall between primary and secondary care, things may be missed. Taking a systematic approach to assessing risk factors, such as blood pressure, and treating them effectively can significantly reduce further stroke risk.
