Myocardial ischaemia is associated with an elevated brain natriuretic pepide level even in the presence of left ventricular systolic dysfunction.

摘要

In three separate populations a consistent finding is that BNP is increased further by myocardial ischaemia even in the presence of LVSD. A disproportionately high BNP for the degree of LVSD might be due to (unsuspected) ischaemia, and a disproportionately low BNP could be useful as a 'rule out' test for ischaemia even in the presence of LVSD.
