Determination of Serum Homocysteine and Hypersensitive C-reactive Protein and Their Correlation with Premature Coronary Heart Disease

Abstract

Background: This study aims to investigate the correlation between premature coronary heart disease (pCHD) and both serum homocysteine (Hcy) and hypersensitive C-reactive protein (hs-CRP). Methods: A total of 170 patients with pCHD were enrolled in this study from June 2014 to April 2016 (including 52 patients with stable angina pectoris [SAP], 70 patients with unstable angina pectoris [UAP], and 48 patients with acute myocardial infarction [AMI]), together with 105 healthy controls (CON) selected at the same period, to observe the changes of Hcy and hs-CRP in CHD patients and those with different types of CHD. Results: The levels of serum Hcy and hs-CRP in group pCHD were significantly higher than in group CON (P < .05). The levels of Hcy and hs-CRP in group AMI were significantly higher than in group UAP and group SAP (P < .05). The changes of serum Hcy and hs-CRP were significantly higher in patients with multi-vascular lesions and dual-vascular lesions than in those with single-vascular lesion (P < .05). Conclusion: The levels of serum Hcy and hs-CRP in CHD patients are positively correlated with the severity of CHD, which increase with the increase of lesion count. The combined detection of Hcy and hs-CRP can initially reflect the severity of coronary artery, thus better guiding treatment and predicting prognosis.
