Sažetak

Aim To assess the concentration of B-type natriuretic peptide
(BNP) as a predictor of heart failure in patients with
acute ST elevation myocardial infarction (STEMI) who underwent
primary percutaneous coronary intervention (PCI)
with successful and complete revascularization.
Methods Out of a total of 220 patients with acute STEMI
admitted to the Sisters of Mercy University Hospital in
the period January 1 to December 31, 2007, only patients
with acute STEMI undergoing primary PCI who had single
vessel disease and were successfully revascularized were
included in the study. Selected patients had no history of
myocardial infarction or heart failure and a normal or nearnormal
left ventricular ejection fraction (≥50%) assessed by
left ventriculography at admission. Only 58 patients met
the inclusion criteria for the study. Out of those, 6 patients
refused to participate in the study, and another 5 could not
be followed up, so a total of 47 patients were evaluated.
Blood samples were taken for measurement of BNP levels
at admission, 24 hours later, and 7 days later. Patients were
followed up for 1 year. The primary outcome was reduction
in left ventricular ejection fraction (LVEF) to <50% after
1 year.
Results Patients who developed echocardiographic signs
of reduced systolic function defined as LVEF<50% had significantly
higher values of BNP (≥80 pg/mL) at 24 hours
(P = 0.001) and 7 days (P = 0.020) after STEMI and successful
reperfusion. Patients who had BNP levels ≥80 pg/mL after
7 days were 21 times more likely to develop LVEF<50 (odds
ratio, 20.8; 95% confidence interval, 2.2-195.2; P = 0.008).
Conclusion BNP can be used as a predictor of reduced
systolic function in patients with STEMI who underwent
successful reperfusion and had normal ejection fraction at
admission.
