title: C-reactive protein as a predictor of cardiac rupture after acute myocardial infarction.
abstract: Although cardiac rupture is the second most common cause of death after ventricular failure in acute myocardial infarction, no diagnosis has ever been made before an episode of clinical compromise, and no significant predictive factors have been described. This study was designed to determine whether high serum C-reactive protein (CRP) levels could predict the incidence of subacute cardiac rupture after acute myocardial infarction. Nine consecutive patients with cardiac rupture were compared retrospectively with 28 consecutive control patients without rupture after acute myocardial infarction. In the rupture group, peak serum CRP levels increased rapidly and markedly after infarction, reaching more than 20 mg/dl on day 2, and persisted at high levels compared with those in the control group. However, the time course and levels of serum creatine phosphokinase were not significantly different between the two groups. High serum CRP levels ( > 20 mg/dl) had a high diagnostic sensitivity (89%) and specificity (96%) for cardiac rupture. Patients with persistently high serum CRP levels, particularly above 20 mg/dl, might have high probability of occurrence of sub-acute cardiac rupture after acute myocardial infarction.
