Correlation between blood asymmetric dimethylarginine level and the complications of patients with cardiovascular diseases.

ABSTRACT

This study aimed to investigate the correlation between blood asymmetric dimethylarginine (ADMA) and the complications of patients with cardiovascular diseases through studying the level changes of ADMA, endothelial nitric oxide synthase (eNOS) and NO. Two hundred research subjects with small differences in gender ratio and age, including 50 patients with hypertension combined with myocardial infarction, 50 patients with hypertension, 50 patients with myocardial infarction and 50 healthy normal controls, were enrolled. Relevant basic indexes were measured and recorded; the blood ADMA levels of all the research subjects were detected using high pressure liquid chromatography (HPLC) within the required time. Furthermore, the levels of eNOS and NO were detected using enzyme-linked immunosorbent assay and the relevant information, such as blood pressure, was recorded. The comparison and analysis results of data obtained through detection demonstrated that the subjects in the four groups were well comparable. It was found that the myocardial infarction combined with hypertension group had a much higher serum ADMA level and relatively low levels of eNOS and NO compared to those of the other three groups; the myocardial infarction group and the hypertension group had a much higher serum ADMA level compared to that of the healthy control group and the two groups had much lower levels of eNOS and NO. Moreover, the serum ADMA level was in a positive correlation with the severity of cardiovascular diseases and it showed a significant difference in patients with different severity of hypertension. The change of blood ADMA level can induce acute myocardial infarction as well as the occurrence of cardiovascular disease-associated complications.
