Abstract:
:1. Neutrophil function was studied in 10 males presenting with acute myocardial infarction (MI) within 6 h of onset and in 10 normal males. Neutrophil production of platelet-activating factor (PAF), determined by bioassay, that of leukotriene B4 by HPLC, and the activity of an enzyme involved in the synthesis of PAF, acetyltransferase (AT), were measured before and after stimulation with opsonized zymosan and calcium ionophore, A23187. 2. The neutrophil count was significantly raised at presentation in those with MI (8.2 +/- 0.8 vs 2.8 +/- 0.3 (s.e.m.) x 10(9) cells/L, P < 0.001; t-test, 18 d.f.). Production of PAF per neutrophil in response to both stimulants was greater than normal in those with MI (zymosan: 21 +/- 4 vs 12 +/- 1 ng/10(7) cells, P < 0.05; ionophore: 174 +/- 18 vs 113 +/- 11 ng/10(7) cells, P < 0.02) despite normal leukotriene B4 production and depressed AT activity. By 7 days, the neutrophil count had significantly fallen but it remained greater than normal as did PAF production. 3. Acute MI is associated with increased potential for production of PAF by neutrophils which may be important in the pathogenesis of MI.
