Introduction: C-reactive protein (CRP) has come to prominence in the cardiovascular field with the inflammatory hypothesis of atherosclerosis. Many studies evaluated the role of CRP as a prognostic marker in ST-segment elevation myocardial infarction (STEMI). The aim of our work was to study the relation between admission CRP level and the angiographic severity of coronary artery disease in patients presenting with acute ST elevation myocardial infarction. Patients and Methods: Admission CRP was measured for 100 STEMI patients before primary percutaneous coronary intervention (PCI). Complexity of coronary lesion was assessed using both Syntax score and thrombolysis in myocardial infarction (TIMI) flow. Results: Syntax score was significantly higher in the 3rd CRP tertile (20.24 ± 5.6 and P = 0.000), TIMI 0 flow was the highest in the 3rd tertile (24% and P = 0.001). We found a significant positive correlation between Syntax score and CRP and a significant negative correlation between CRP and TIMI flow (P = 0.001 and 0.005, respectively). Receiver operating characteristic curve constructed to determine the sensitivity of admission CRP to determine intermediate to high risk SYNTAX score showed a level ≥8.4 mg/dl as 71% sensitive (area under the curve [AUC] =0.65 and a P = 0.02) and an admission CRP of ≥4.8 mg/dl to be 81% sensitive in determining no or faint antegrade flow (TIMI 0 and 1) (AUC = 0.71. P =0.001). Conclusion: There is a strong positive correlation between admission CRP and the syntax score and TIMI flow in STEMI patients undergoing primary PCI, thus adding CRP to the risk scoring systems used to assess STEMI patients before PPCI can help better risk stratify patients before going into the cath laboratory.
