The predictive value of white blood cell count on the success of primary percutaneous intervention of the left anterior descending artery in patients admitted with acute anterior wall myocardial infarction.
Background: Epidemiological studies have shown correlations between the white blood cell (WBC) count and the risk of acute myocardial infarction (AMI) and stroke. The risk of AMI is four times as great in patients with WBC counts in the high-normal range (>9000/microl) as it is in those in the low-normal range (<6000/microl). A high WBC count also predicts a greater risk of re-infarction and in-hospital death. ⋯ Multiple logistic dregression analysis demonstrated that low ejection fraction (p=0.01) and high WBC counts (p=0.04) were correlated with failure of angioplasty and referral for an emergency CABG. WBC counts were positively correlated with heart rate (p=0.005), platelet count (p=0.0006), and Hg level (p=0.001). Conclusions: These data suggest that measuring WBC count on admission to the catheterization laboratory for primary angioplasty provides clinically important prognostic information.
