Key result
Persons in the top 10% of systolic blood pressure distribution experienced only 21% of all IHD events and 28% of all strokes, demonstrating that blood pressure is a poor screening test.
Why the study?
Are blood pressure and other cardiovascular risk factors effective screening tests for identifying individuals who will develop ischemic heart disease or stroke?
Are blood pressure and other cardiovascular risk factors effective screening tests for identifying individuals who will develop ischemic heart disease or stroke?
Blood pressure and combined cardiovascular risk factors are poor screening tests for predicting IHD and stroke; age and prior cardiovascular events are more effective identifiers of high-risk individuals.

Questions BP-based screening for IHD/stroke; leaves open whether age or prior events better stratify risk in prospective studies.
Law et al. (2004) conducted a review in Ischaemic heart disease and stroke. Blood pressure and cardiovascular risk factor measurement was evaluated on Identification of incident ischaemic heart disease or stroke. Persons in the top 10% of systolic blood pressure distribution experienced only 21% of all IHD events and 28% of all strokes, demonstrating that blood pressure is a poor screening test.
