to investigate the prostaglandin i2 ( pgi2 ) half-life regulated by high density lipoprotein ( hdl ) in patients with coronary artery disease ( cad ) , we determined the stability of pgi2 and serum apolipoprotein a-i ( apo a-i ) and apolipoprotein a-ii ( apo a-ii ) levels in four age-matched groups of patients : controls ( n = 17 ) , angina pectoris ( n = 18 ) , unstable angina pectoris ( n = 17 ) , myocardial infarction ( n = 19 ) ( acute phase , 3.6 +/- 1.7 hours from onset ; subacute phase , 75 +/- 15 hours from onset in the same patients ) .
