Serum complement (C3, C4) levels in Libyan patients with acute myocardial infarction (AMI; 31 patients) and angina pectoris (AP; 11 patients) at the 1st day and 7th day of attack were estimated. A group of 26 healthy Libyans were taken as control subjects (CS). Serum C3 and C4 levels (mean ± SD, mg/dl) were elevated at the 1st day in AMI as well as AP patients (C3Æ AMI1: 154.0 ± 28.5, AP1: 152.0 ± 45.0, CS: 132.0 ± 8.0, ANOVA: p=0.0072; C4Æ AMI1: 38 ± 13, AP1: 37 ± 17, CS: 29 ± 6, ANOVA: p=0.0160). No significant differences for the elevated C3 and C4 levels at the 1st day were observed between the two diseases groups (AMI1 vs AP1Æ C3: p=0.879, C4: p=0.818). At the 7th day, C3 and C4 levels were further elevated in AMI, while they remained at the similar elevated levels in AP (C3Æ AMI 7: 173.1 ± 28.0, AP 7: 149.0 ± 41.0, CS: 132.0 ± 8.0, ANOVA: p=0.0000; C4Æ AMI 7: 46.0 ± 7.0, AP 7: 36.0 ± 15.0, CS: 29.0 ± 6.0, ANOVA: p=0.0000).
