Abstract
To better understand the pathogenesis of the post-cardiac injury syndrome (PCIS) 2 models of cardiac injury were studied. One hundred twenty-nine patients who underwent cardiac surgery and 80 patients with acute myocardial infarction (AMI) were prospectively followed and the levels of anti-heart antibodies (AHA), anti-actin antibodies (AAA) and anti-myosin antibodies (AMA) were determined. In the surgical group, PCIS developed in 27 patients (21%) and incomplete PCIS in 36 (28%). In the AMI group, PCIS did not develop in any patient, but incomplete PCIS developed in 11 patients (14%) (p less than 0.001). The surgical group showed a significantly higher humoral immune response than the AMI group when analyzed for AHA and anti-contractile protein antibodies. After cardiac surgery, AHA developed in 59 patients (46%), AAA developed in 33 (26%) and AMA developed in 49 (38%); in the AMI group, significant levels of AHA, AAA and AMA developed in 16 (20%), 7 (9%) and 13 patients (16%), respectively. These studies show a significant correlation between the PCIS clinical classification and auto-antibodies raised against heart contractile proteins.
