In order to study the prognostic value of high-sensitivity C-reactive protein (hsCRP) and lipoprotein (a) Lp(a) in patients receiving emergency percutaneous coronary intervention (PCI) following acute myocardial infarction (AMI), we retrospectively reviewed 118 patients who received emergency PCI following AMI from January 2007 to April 2010. The plasma levels of hsCRP and Lp(a) were determined. The incidence of cardiovascular events was compared between patients with an elevated hsCRP level and those with a normal hsCRP level and between patients with an elevated Lp(a) level and those with a normal Lp(a) level. Results showed that the incidence of cardiovascular events was 52.9% in the hsCRP-elevated group and 18.2% in the hsCRP-normal group displaying a significant difference (P=0.011). However, the incidence of cardiovascular events was 35.3% in the Lp(a)-elevated group and 46.4% in the Lp(a)-normal group and statistical analysis revealed no significant difference (P=0.733). HsCRP, but not Lp(a), can serve as a prognostic factor for patients receiving emergency PCI following AMI. Kako bi se utvrdila prognostička vrednost visokoosetljivog C-reaktivnog proteina (hsCRP) i lipoproteina (a) Lp(a) kod pacijenata podvrgnutih hitnoj perkutanoj koronarnoj intervenciji (PKI) posle akutnog infarkta miokarda (AIM), retrospektivno je analizirano 118 pacijenata podvrgnutih hitnoj PKI posle AIM između januara 2007. i aprila 2010. Određeni su nivoi hsCRP i Lp(a) u plazmi. Upoređena je incidenca kardiovaskularnih događaja kod pacijenata sa povišenim nivoom hsCRP i onih sa normalnim nivoom hsCRP, kao i između pacijenata sa povišenim nivoom Lp(a) i onih sa normalnim nivoom Lp(a). Rezultati su pokazali da je incidenca kardiovaskularnih događaja bila 52,9% u grupi sa povišenim hsCRP i 18,2% u grupi sa normalnim hsCRP, što je ukazalo na značajnu razliku (P=0,011). Međutim, incidenca kardiovaskularnih događaja bila je 35,3% u grupi sa povišenim Lp(a) i 46,4% u grupi sa normalnim Lp(a), a statistička analiza nije otkrila značajnu razliku (P=0,733). HsCRP, ali ne i Lp(a), može poslužiti kao prognostički faktor kod pacijenata podvrgnutih hitnoj PKI posle AIM.
