[Serum high-sensitivity C-reactive protein level in patients with coronary heart disease complicating with or without metabolic syndrome].

Objective: To observe the relationship between serum high-sensitivity C-reactive protein (hs-CRP) level and coronary artery lesion in patients with coronary heart disease (CHD) complicating with or without metabolic syndrome.

Methods: CHD was confirmed in 170 out of 227 patients who were admitted into Peking union hospital because of chest pain by coronary artery angiography (CAG). Metabolic syndrome was diagnosed in 79 out of 170 CHD patients (MS group) and the relationship between serum hs-CRP level and coronary lesion was compared to CHD patients without metabolic syndrome (non-MS group).

Results: The number of CHD patients who had type B and C coronary stenosis and the serum level of hs-CRP was significantly higher in MS group than those in non-MS group, especially in patients with the serum level of hs-CRP > 3.5 mmol/L.

Conclusion: For CHD patients complicating metabolic syndrome, hs-CRP is a reliable marker to predict the severity of coronary artery lesion.
