Novel biochemical markers may improve the estimation of overall risk in subjects at a high risk of adverse cardiac events. Measurement of some of these markers, including pregnancy-associated plasma protein A (PAPP-A), brings significant prognostic information independent of traditional risk factors. PAPP-A has been recently identified as a marker of plaque destabilization with growing interest in cardiovascular research. Our group has recently demonstrated that higher levels of serum PAPP-A were independently associated with an increased short-term risk of cardiovascular events in a large sample of 2568 consecutive patients presenting with cardiac chest pain. PAPP-A levels above 34.6 mIU/l in cardiac chest-pain patients sets alarm bells ringing as a warning for higher risk of short-term cardiovascular adverse events, including stent thrombosis, myocardial infarction, ischemic stroke or cardiovascular-related death within 90 days, the combined primary end point of this study. Cardiac chest pain patients with PAPP-A levels above 34.6 mIU/l may suffer from adverse cardiovascular events five times more frequently within 90 days than those with lower PAPP-A levels (hazard ratio: 5.28; 95% CI: 3.81-7.31). However, current data do not support the diagnostic role of PAPP-A for acute coronary syndrome in comparison to the gold standard biomarker troponin. Additionally, PAPP-A is known to interact with heparin, which may diminish its potential utility in every day clinical life. Future multicenter and large-volume studies are warranted to validate the use of PAPP-A in routine clinical practice.
