Predictive value of plasma asymmetric dimethylarginine, homocysteine, and high-sensitive CRP levels in occult coronary artery disease: A multidetector-row computed tomography study
Abstract
Multidetector-row computed tomography (MDCT) is an attractive noninvasive imaging modality for detecting coronary atherosclerotic plaques, which may be underestimated by conventional angiography. The aim of our study was to determine the predictive value of plasma asymmetric dimethylarginine (ADMA), homocysteine, and high-sensitivity C-reactive protein (hsCRP) levels for occult coronary artery disease (CAD). Thirty-five patients with angiographically normal coronary arteries (NCA) were consecutively included in our study. They underwent MDCT including indications and were divided into an NCA group (18 subjects, 8 male, 46 ± 8 years) and an occult CAD group (17 subjects, 11 male, 48 ± 9 years), with respect to the presence of coronary plaque. Plasma ADMA, homocysteine, and hsCRP levels were measured in blood samples. Plasma ADMA and homocysteine levels of the occult CAD group were significantly higher than those of the NCA group. A nonsignificant trend was observed for higher serum hsCRP levels in the occult CAD group. Receiver operating characteristics analysis revealed that an ADMA level of > 0.71 μmol/l could predict patients with occult CAD (sensitivity, 76 %; specificity, 67 %). The discriminative power of ADMA in distingui...Continue Reading

Atherosclerosis Disease Progression
Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
