The relationship between oxidized low-density lipoprotein (Ox-LDL) and C-reactive protein (CRP) in patients with acute coronary syndrome (ACS) is unknown. We, therefore, measured serum levels of Ox-LDL and high-sensitivity (hs)-CRP in 90 ACS patients, 45 stable angina pectoris (SAP) patients, and 66 healthy controls using sandwich ELISA. ACS patients were subdivided into: (1) acute myocardial infarction (AMI; n = 45); (2) unstable angina pectoris (UAP; n = 45) groups. In AMI patients, Ox-LDL (177.5 mmol/l) and hs-CRP (25.40 mg/l) levels were significantly higher (P < 0.01) than in UAP (Ox-LDL:107.5 mmol/l, hs-CRP:10.7 mg/l) and SAP (Ox-LDL:82.3 mmol/l, hs-CRP:2.10 mg/l) patients as well as controls (Ox-LDL:41.4 mmol/l, hs-CRP:1.76 mg/l). Ox-LDL/hs-CRP levels in UAP patients were significantly higher (P < 0.01) than in SAP patients and controls. Importantly, a positive correlation was found between Ox-LDL and CRP (r = 0.622; P < 0.01) levels. Serum levels of total, HDL, and LDL cholesterol did not differ among these patient groups. In conclusion, our data show that Ox-LDL and hs-CRP levels correlate positively in ACS patients, supporting the hypothesis that Ox-LDL and CRP may play a direct role in promoting the inflammatory component of atherosclerosis in these individuals. We suggest that Ox-LDL/CRP elevated levels may serve as markers of the severity of the disease in evaluation and management of ACS patients. |
